Adolescence
may be late, and difficult for families to cope with. It may also be a difficult
time for the young person, as they see their peers developing physically
and sexually and shooting up in height. Types of behaviour, which occur earlier
in normal children, may appear even more inappropriate when they occur much
later. Adolescence is also a time of greater freedom for the young person
and this all too easily may include freedom of access to food, sweets etc.

Adult Training
Centres provide supported training and employment opportunities
for people with learning disabilities. Some people with PWS may find Adult
Training Centres rather limiting. Activities on offer vary considerably,
and some centres are better at managing the dietary and behavioural needs
of people with PWS than others. You therefore need to check them out thoroughly.
Some of the activities which may be found include:
The special needs and nature of PWS needs to be explained fully to support staff.

Age and the effect
of it on the abilities and progress of people with PWS, has not been studied
because, until relatively recently, life expectancy was limited, and few
people with the syndrome were known over the age of 40. Abnormally high blood
pressure and diabetes have been found to be the major health problems of
older people with PWS, together with obesity, osteoporosis, restrictive lung
disease, oedema and cellulitis. Strokes, heart diseases and cancer do not
appear to be so common.
With greater awareness of the syndrome, older people with PWS are being recognised (a recent case of a British family on holiday in New Zealand led to the diagnosis of a 43 year old woman). Better dietary understanding and management mean that young people can now look forward to a more normal life span (recently, a person with PWS died at the age of 71). There is a general consensus that behavioural problems seem to settle down by the late 20s.

Aggressive
Behaviour is known in people with PWS, and when control is
lost, it can be lost completely. Each person exhibiting it will need to be
handled in a way which is appropriate for them. Sanctions - finding something
that they dislike and threatening them with it - do seem to work. There is
usually a reason for particular behaviour and if detailed records are kept,
an intervention may be found which will modify it. On balance, people with
PWS are volatile.

Alcoholic
Drinks have a high calorie content but some drinks are better
than others. Clearly, lower alcohol drinks are likely to be a better bet
than those with high alcohol content. Low alcohol wines are relatively palatable
now and are also low in calories (typically 45 calories for a small glass).
Spritzers of dry wine (or low alcohol wine) and mineral water or soda provide
a longer drink for relatively few calories. Shandies can be made with diet
lemonade (not easily available but, if the same pub is used regularly, the
landlord may be persuaded to provide it) and this reduces the calorie content.
Going to the pub' can be a very rewarding and helpful socialising experience
for someone with PWS.

Allowances for
people with disabilities and their carers are an entitlement. However,
given the nature of bureaucracy, there may be problems in initially obtaining
allowances. Some parents get disability allowance, others are refused. The
PWSA(UK) can help families with
information
and to fill in forms and to lodge appeals. It is important to claim all those
allowances to which the person with PWS or their carer is entitled, since
these can help to validate the need for services later.

Ambitions are
just as natural in people with PWS as in the rest of the population. But
those who have PWS need counselling and support to realise that some of their
ambitions may be unrealistic. For instance, a person who wishes to become
a vet could be gradually persuaded that helping out at the local animal rescue
centre is just as important; for others, the idea of marriage may require
a great deal of support and advice from social workers, parents, and carers,
and may not be the romantic ideal which they think it is; many will have
to realise that having children will automatically accompany adulthood or
follow marriage.
The situation is not helped by well-meaning people encouraging them to believe that they can achieve anything they want. All people have their dreams; those who have Prader-Willi syndrome have to face a life in which these dreams will less rarely become reality than the dreams of others, and that there are not many, appropriate, alternatives on offer.

Angelman
Syndrome might be considered as a sister syndrome to PWS,
caused as it is, by abnormalities in the maternal 15th chromosome rather
than the paternal. There are a number of
on-line sites providing
information about Angelman Syndrome. It would appear that people with AS
also have poor temperature control and, particularly as young children, may
show a craving for food and eat copiously while remaining thin and wiry!

Behaviour - People
with PWS have some challenging behaviours which appear to be more common
in the syndrome than in people with other learning difficulties. These include
temper tantrums, skin picking, obsessiveness, perseveration and stubborness.
The severity of challenging behaviours varies from one person to another.
It is not known whether this is because of physical, organic or genetic
differences, or because of better or worse behavioural management on the
part of carers. Generally speaking, people with PWS need to maintain their
self-esteem and can do this within a loving, but firm, environment.

Brain Research on
the effect of PWS on the brain is taking place (Hammersmith Hospital), but
progress is slow because of the difficulty in obtaining post-mortem brains.
Donating the body of someone close to you for medical research may be more
difficult than donating organs to save or improve a life, but brain research
does offer the possibility of greater understanding of the neurology of PWS
and the possible future alleviation of some of the symptoms. The PWSA(UK)
has set up a brain donor database in collaboration with researchers and welcomes
enquiries about brain donation. 1t is not thought that PWS can be cured by
brain surgery at this time.

Case
Conferences need to be approached seriously to obtain the
appropriate provision of services for the person with PWS. If you feel
intimidated at facing a panel of professionals you can always take someone
to support you. Advice or help may be available from the PWSA(UK).
There is always the problem of injuring a child's self esteem on these occasions and, perhaps, a case for holding a preliminary meeting, at which the child is not present, which will give all concerned a chance to iron out any problems. [In one case a support group, consisting of the doctor involved with the case and the worker taking on the role of advocate, had been formed. They discussed the client's problem, and admitted that they did not realise how traumatic the situation was for him. They asked if they should go to meetings for him, in order to state his case. It would depend on him trusting them, and taking responsibility for other areas of his life, however. He was asked to keep his weight stable, and in fact lost a little weight, and his behaviour improved. Recently he was persuaded to attend a meeting, just to collect praise. He was uneasy at this, but the strategy did seem to be working].

College of Further
Education courses for those with Special Needs are increasingly

constraints of the person with PWS; temptation could be removed, for example,
if lunch boxes were kept locked away until needed. The learning disabled
young person is entitled to free education until the age of 25. Residential
education is a possibility but the rules for funding are more difficult.

Communication
problems are present for most people with PWS: problems with
speech,
perseveration,
and of understanding. Young people with PWS may not be listening to what
someone else is saying, concentrating instead on what they want to
say. It is important to focus their attention. Speech therapy is about more
than just articulation and should be considered for young people with PWS.
Return to Home Page |

Communicating the
problem is essential. Telling the child about PWS should be
done as early as possible, and acceptance of the condition part of everyday
life. With older children, who have not been told, introduce the subject
gently, possibly around membership of the Association and receipt of
communications from it. All professionals dealing with the child (medical,
educational and welfare) must be made aware of the condition. Good communication
between parents and professionals is essential. An example was given of hospital
staff being told that a child was to be kept on a low-calorie diet and totally
ignoring this, because the child was quite slim. As a consequence the child
gained several pounds during the hospital stay.

Control can be
central to some of the behavioural problems in PWS. Children with the syndrome
may resent their lives being controlled by others, and this is particularly
so as they grow older and reach adulthood. As much control as is safe must
be vested in the person. It must be very difficult for an adult to know that
they are being continually watched, even spied upon, and their basic everyday
needs, as it were, restricted.

Counselling
may be very helpful for parents to come to terms with the diagnosis in the
early years. This requires a specialised approach following a lot of trianing.
Professional counsellors should be used. Parent to parent support may be
available through the PWSA(UK) in some areas.
In teenage and later years, counselling may be helpful for the person with PWS, themselves, to come to terms with their syndrome and with the problems it causes in their lives. Counselling youngsters about diet is difficult. Saying, "Eating too much may make you ill or kill you" may have little effect, as the continuing success of the tobacco industry indicates. Pointing to the availability of more stylish clothes for the slimmer person or the greater ease of participating in physical activities may be a better bet. At the 1997 conference in Coventry, adults with PWS stated clearly that they found emphasis on the risk of an early death unsettling and unhelpful.

Dentists may refuse
to take NHS patients but your Health Authority should be able to refer you

have consequences for teeth & gums. Hormone treatment may alter the normal
course of growth and development and this may too have oral consequences.
Reported problems include micrognathia (small jaw) which may lead to crowding
and subsequent referral to an orthodontist, hypoplastic enamel leading to
enamel attrition, which may be treated with a suitable coating, unusual and
sticky saliva, and poor dental hygiene, which can be improved with instruction
from a dental hygienist.

Diabetes can occur
in people with PWS although the incidence is not known. The usual cause of
diabetes in PWS is obesity.
Return to Home Page |
Back to the Top |
Diagnosis is
easier and more likely now that diagnostic criteria are available to all
paediatricians in the UK. Although it may appear that the number of children
being diagnosed is increasing, the truth may well be that this is probably
due to increased awareness of the syndrome. Despite the fact that some
paediatricians may be reluctant to 'label' a child, early diagnosis is thought
to be essential from the dietary point of view. An additional advantage of
early diagnosis is that parents can then get a 'framework' for the rest of
their lives, and the young person can grow up with an appropriate life style.
There is still a chance of having an undiagnosed person with PWS in any large group of people, e.g. a school. Relatively recently the Association came across a 44 year old man, who had only been diagnosed six months before.
Diagnoses must be given promptly and with sensitivity. They have been known to have been given over the telephone, with minimal supporting information, or found out by reading the baby's notes at the foot of the bed. Parents have been given out-of-date information, emphasising only the problems and possible worst case scenario, photocopied from medical textbooks. This is not appropriate. The importance of early diagnosis cannot be emphasised too much. There are still occasions when it is difficult to get a firm diagnosis. This affects access to support services, and makes it harder to convince other professionals that there is, indeed, a problem.

Diet is for life,
not just for a while. Those who are taught about their eating problems, and
the need for self-discipline, whilst at home, appear to have more self-discipline
when they leave home.
It sometimes pays to give the person with PWS a small portion of what everyone else is having. In fact, this can form a useful behavioural strategy, allowing the person with PWS to share (albeit in a limited way) with their family and peers.
Return to Home Page |

Dietary
Management is an essential fact of life for those with PWS.
Some youngsters appear not to conform to the stereotype and can cope better
with appetite, so there may be varying degrees of desire ranging from mild
to acute. It is possible that hereditary factors may come into play, or that
families with a tendency to obesity may well produce children who become
obese. Whatever the case, it is important that dietetic advice is sought
from the weaning stage.
Food is a central part of family life, and it is important to educate the child about the necessity for diet, from an early age, e.g., "If you eat too much, you won't be able to run about." Some parents have found that 'conditioning' from an early age works.
Children with PWS love to talk about food and the next meal. They like to think about it, talk about it, prepare it, and, of course, eat it. They are quick to realise the significance of actions relating to food. The fact that they are able to 'cue in' to these actions would seem to indicate that they might be able to be 'cued' in to other things.
Pre-school opportunity groups may not always recognise the problem of controlling food intake. If a parent insists that biscuits are put away during the session, does this affect the rights of other participating children? Solutions might include the provision of a 'special' biscuit for children who had PWS or enrolling the assistance of participating parents by giving them a short talk about the condition.
Some parents feel guilty about locking away food. There is a need for independence in food selection - a need to build in choice and decision making, although full independence is unlikely. Be creative, provide suitable food from which the choice may be made. It has been suggested that a high fibre diet makes the stomach feel more full but, as far as we know, this has not been shown to work.
Remember people with PWS prefer eating to drinking and it may be necessary to remind them to have a drink occasionally. Diet drinks are fine, with one to two bottles a week as a guide. Fruit juice does contain calories and acid (which can harm teeth, and which is also present in cola) and should be counted in the daily calorie intake..
It is always better if the child can be educated to get used to smaller amounts of food. Since the person with PWS seems not to experience feelings of satiety, it is better to educate them to use other cues for an appropriate amount to eat - for example the visual appearance on the plate. No drugs have been found successful in the suppression of appetite in PWS, and if they were, they would be unlikely to overcome the rigid and stubborn personality traits.
Problems can occur with stealing and foraging, and on outings. Delays to expected meal times can cause tantrums.
Early diagnosis of the syndrome is essential. Everyone caring for the person needs to be educated about their special dietary needs and that includes the person with PWS. The PWSA(UK) has produced a number of guides including Food and Health, and Notes for dietitians. To many people, who are affected by the syndrome, the word 'diet' is like a red rag to a bull. We may need to start using alternative terminology, e.g. 'healthy eating' or 'nutrition' and avoid talking about 'reducing' meal size or 'dieting'. A video film, charting weight loss, can be a source of pride and motivation and daily weighing with the weight plotted on a simple line graph may help to encourage the individual.
Distraction may take the mind off food, or it may not, depending on the individual. Some individuals can seem to forget about food when they are involved in an activity they enjoy, sometimes for surprising lengths of time.
Cookery lessons, and food preparation in general, are issues that need to be considered carefully, particularly in relation to independence and rights. Supervision and control are probably necessary. In school, Food Technology teachers must be made aware of the situation and expected to tailor recipes to be low calorie.

Education
about the syndrome is necessary for parents, carers and professionals
and for the person themselves.
The choice of school is paramount and while it may seem at first to be a choice between mainstream, special or residential school, it is probably more important to make sure that the school chosen has a calm atmosphere and a caring philosophy, one that values every individual in the school and not just the academic and sporting high fliers.
A Statement of Educational Needs should be sought and advice taken in arriving at it. Remember, it is the needs of the child that are supposed to be addressed, and therefore the Statement should consider more than just academic needs - the child with PWS also needs to be taught dietary management and social and living skills. More detailed notes are available on the subject of the education of the child with PWS.

Employment for
people with PWS is complicated by their craving for food, their inflexibility
and, at times, their unyielding determination to do things their way.
A few are able to get part-time employment, and one or two are known to be
in full-time employment but for most them the answer appears to be some form
of supported employment such as Adult Training Centres (see above).
One young girl had proved to be very good at dressing and changing babies and young children, but had spent more time talking to adults about them than playing or working with the children.
Office work had been tried by one student who already had a couple of GCSEs, but she was easily distracted by other things happening in the office, and stopped what she was doing. She would also refuse to carry out a task, if she did not feel like doing it. One other young man does work in an office where they are sympathetic to his needs.
One girl had a job in a staff canteen, but this was not an appropriate placement as the temptation to eat left-over food was too great.
One young man had a job with a small builder but lost it when he stole the other workers' lunches.
However, one young woman has a job chopping wood for the community in which she lives, which gives her a sense of importance.
One person helps with a milk round - employment with exercise, perfect!
Employers must know what they are taking on, when they employ somebody who has PWS. They should be given a contact number and asked to ring immediately there are problems or the placement will break down, and the blow to the employee's self esteem will be crippling. Some local authorities are setting up Work Assessment Centres to take disabled people and see if they can find work in the community.

Exercise is even
more desirable for those with PWS than for most of us. Exercise not only
burns up calories but also increases muscle mass, which then burns further
calories. Weight loss will not necessarily be immediate since muscle weighs
more than the fat it initially replaces. Exercise may vary from a fifteen
minute walk to a cardio-vascular workout in a sports centre. Exercise with
weights may be ill-advised before bone growth is complete, and advice must
first be taken from an endocrinologist or paediatrician.

Exclusion from
physical exercise because of weight, or from contact with food because of
the need to restrict intake, may lower self-esteem and lead to poor self-image.
Worse still, is exclusion from the company of peers because of poor social
skills or odd behaviour, and this can lead to strong feelings of loneliness
and misery.
There is always a danger that in our concern to care for and protect learning disabled people, we may ourselves exclude them from taking as appropriate a role as possible in society. For example, we may restrict their participation in decision making about their lives, or we may discourage boy friends or girlfriends because of our own inability to handle the issue of sexuality (one young woman at the Coventry conference expressed considerable anger that she and her boyfriend with PWS, who has since died, were prevented from marrying).
The PWSA(UK) is increasingly trying to include people in its organisation and decision making and in the services it provides.

Failure to Thrive
is common during the first stage of the syndrome. Feeding problems are common:
newborns often have very poor suck; they may fail to awake for feeding sessions
and when woken may appear listless and disinterested. Often this leads to
inadequate intake of energy and nutrients and results in poor weight gain.
Sometime after the age of one year this failure to thrive gives way
to the second stage of PWS - a seemingly insatiable, indiscriminate appetite.

Families need
to be fully educated about the syndrome and committed to supporting the
appropriate restriction placed on the person with PWS. Existing relations
(grandparents, uncles, aunts etc.) and new relations (step parents, in-laws)
need help to come to terms with the syndrome and information to understand
it. One grandparent understood that his granddaughter with PWS could not
have regular presents of ordinary chocolate, but failed to appreciate that
diabetic chocolate may lack sugar but still contains fat. The PWSA(UK) has
now published a special leaflet for
grandparents,
and encourages them to become members of the Association and to attend
conferences.

Family Life
and relationships can be radically altered by the inclusion of a member with
PWS. It is even more important that parents present a united front in dealing
with the child with PWS, than it is in raising their other children.
The needs of the other children in the family do need to be remembered and addressed, as do the needs of each parent. One brother recounted how he never had any money, or went shopping alone, because his elder sister had PWS, and this had set the precedent. Brothers and sisters need to be informed about the condition that their sibling has - considerable concern at being uninformed and uninvolved in planning for their disabled sibling has recently (Oct. '97) been the subject of a sibling chat forum.
It is important to appreciate the stress that may be caused to a family which has a member with PWS. Although, superficially, the child may not appear to be particularly handicapped, or difficult to care for, they can be a chronic burden and occasionally the difficulty in caring for them becomes intolerable; there should be provision for Respite Care (the PWSA(UK) may be able to advise on this). The PWSA(UK) Local Group can have its place and value in offering family support. Where none exists, parents should consider starting one, or pairing up with another family to provide a friend for their child and to exchange ideas or respite care. Sometimes, parents attending local support groups do find it depressing at first, but often begin to feel the value of the support offered after several meetings.

Feeding Problems
immediately after birth are typical (found in 93% of cases according to the
Pediatric Database). It is common for feeds in the early weeks to be by tube
and even for parents to take their babies home from hospital tube feeding
them, once they are confident to do so themselves.

Food
Labelling may still need improving but is better year by year
and better in the UK than in some other countries. Supermarket shopping for
the family with PWS becomes a completely new experience, particularly in
the early days, as every purchase needs to be examined for fat and sugar
content.

Funding, or rather
lack of it, can be a barrier to the provision of suitable services for the
person with PWS. Be sure to claim the Allowances to which you and the young
person are entitled. Funding for the 19-21+ age group, for respite care,
and for educational and permanent residential care, may be slow and difficult
to obtain. Planning and early application is recommended.

The Future needs
to be thought about and planned for from an early age. As soon as possible,
involve siblings and other family members. In particular, planning for when
the child leaves school should start by the age of 14, to give plenty of
time to ensure that the correct support is in place. Every child with a Statement
of Educational Needs should have a Transition Plan prepared shortly after
their 14th birthday as part of the Statementing process.

Guilt is not an
appropriate feeling for parents of a child with PWS. Some parents do experience
enormous feelings of guilt about their child's handicap, blaming themselves
for its occurrence but, the truth is, that nothing they could have done would
have prevented it from happening. Diagnosis not only brings with it a better
understanding of the problems, and information about how to deal with them,
but may help parents who feel that their child's behaviour or condition was
due to some fault of theirs, to shed their sense of guilt.

Holidays are not
a break from food supervision and a secure environment. Parents may be wary
about sending their children away because experience shows that, despite
the willingness of the organisers to implement dietary requirements, weight
will creep up in many cases. Making sure that teachers and youth leaders
or other organisers are fully informed of the seriousness of the dietary
restrictions will certainly help. Being prepared to send along diet drinks,
artificial sweeteners, or other special foods may help. The PWSA(UK) may
be able to help with lists of holiday accommodation which has experience
of people with PWS or with people with learning difficulties in general.
When funding is available, the PWSA(UK) does organise BREAK holidays for
young people with PWS.

Hypotonia, or
weak muscle tone, and floppiness at birth is one of the diagnostic
characteristics of PWS. This floppiness is often so pronounced initially
that the ability to suck is reduced to the extent that the baby will require
tube feeding for the first few days or weeks of life. Physical milestones
such as sitting, standing and walking are much delayed with the infant typically
first walking after the age of two.

The
Incidence of
PWS is thought to be about 1:15,000 to 1:20,000 live births. There appear
to be areas where there are very few known cases, and areas where there are
relatively many. This is thought to be linked to levels of awareness and
experience in professionals, e.g. teaching hospitals would seem to have pockets
of greater incidence around them. Not all families join the Association,
so it is not possible to say, with any certainty, whether cases are evenly
distributed across the country or not. Race or sex are not thought to be
variables in the incidence of PWS.

Identity Cards
for people who have PWS can be obtained from the PWSA(UK). These can be used
if they get into trouble or have an accident. They may help to explain the
craving for food is so strong that shoplifting, for example, is not seen
as mere delinquency.
Return to Home Page |
Back to the Top |
Independence
may never truly be achieved by the person with PWS. It seems that, inevitably,
independence leads to overeating and weight gain, which in its turn leads
to lack of independence due to want of mobility, and poor health. Intervening
to restrict the diet, while not offering true independence, may offer a greater
opportunity for physical independence and better social integration. No longer
having to take personal responsibility for resisting food, may allow the
person with PWS to feel a great BURDEN has been lifted from their shoulders.
In a life threatening situation, independence is not a priority.
When IQ is relatively high in people with PWS, they are aware of what they can and cannot do, so some degree of independence is essential, but total independence is probably not feasible. It is wise to be realistic about what can be achieved. Proper placement and proper daytime placement, i.e. sheltered, supported living, may be a good alternative to independence. We are not aware of anyone with PWS who has lived totally independently for more than a couple of years at a time successfully.
Social workers often disagree with parents about the degree of independence which a post 16 year old with PWS can have. This can lead to the risk of relaxation of strict control of food and food buying. A parallel with diabetes is relevant. Both are life threatening conditions, and no one queries that a diabetic should have a restricted diet. However, it is true to say, that a diabetic can usually cope with restricting their own diet. In addition, if a diabetic takes the wrong food, the effects are immediate, and easily detected; with PWS the effects are longer-term and harder to control. If you find yourself in conflict with a Social Service department that appears not to understand the true nature of PWS, the PWSA(UK) may be able to help as an informed mediator.

Information
about the syndrome is becoming easier to find. It should be spread as widely
as possible. Ideally, everyone who comes into contact with the person with
PWS should be educated about it. If you maintain a Web page, please put a
link to our home page on it.
Return to Home Page |

Intelligence
and Comprehension are not the same. People with PWS may record IQs in the
normal range but the spread of their abilities is mixed. People with PWS
may often appear more able to cope than they really are. Conversely, when
exhibiting traits of perseveration or inflexibility and stubbornness, they
can appear much more limited than they really are.
The IQs of people with PWS are an imprecise measure of their true ability, because of the uneven scatter of abilities in the measures used to arrive at a global IQ figure. Most children with PWS have some learning disabilities although a significant number, perhaps as many as half, fall within the normal or borderline range. Several people with PWS have gained GCSEs.
Return to Home Page |

Isolation is
the lot of many children with learning disabilities due to the accompanying
poor social skills. Inevitably, the management of PWS will serve to further
isolate the child from its peers (it may be beneficial to allow the odd forbidden
food in social situations). Temper tantrums, perseveration, and inflexibility
all contribute to peers isolating the child with PWS. Social skills need
to be taught and should be included on the child's Statement of Educational
Needs.
Isolation can also be experienced by people with PWS of all ages, since they may experience feelings of being the only person with PWS. It is good for them to meet others with the syndrome, and to realise that they are not entirely alone. If they do not meet others at local groups, the annual conference may be the only opportunity for them to share experiences and problems with others with the syndrome. It can be argued that the only person who really understands someone with PWS is another person with PWS, the only true peers are others with PWS. (During a break at the Coventry conference (1997) a group of teenagers and young adults eagerly shared experiences of being called names and strategies for dealing with it; a problem shared does not disappear but it does help to know that you are not the only person to suffer it).
Parents, too, may feel isolated, because there are so few families in any one area who have a child who has PWS. The unsociable aspect of the eating disorder can make parents feel isolated from the rest of society.
Return to Home Page |
Back to the Top |
Leisure
Activities are limited by the child's practical skills. Give
thought to what they can do. People with PWS seem to enjoy sedentary
activities such as sewing, jigsaws, word puzzles, solitaire etc. Many seem
to enjoy board games and card games (possibly because of the structured 'rules'
that go with them). Such games provide an opportunity to join others within
a structured setting. It may be difficult for them to take part in activities
with peers (causing further isolation) because they lack natural physical
skills and physical co-ordination. Parents and schools should consider spending
time (which may be considerable) helping them to acquire simple ball skills,
learning to swim and cycle and skate, and to roll a ball down 10 pin bowling
alley lane, or to acquire a basic ability at whatever the latest craze is.
To take the pressures off parents and the rest of the family, enquire about befriending schemes from your local Social Services department or Council for Voluntary Service. The aim of these schemes is to provide a volunteer for a few hours each week to befriend the person, take them on outings, or just sit and chat.

Life
Expectancy may be stated in older publications as late teens,
early twenties, with death occurring due to complications associated with
obesity (heart failure, diabetes). The situation today is much more optimistic,
with life expectancy largely depending on dietary management.
Despite early diagnosis, some parents have expressed the opinion that dietary management is not worth the effort, and that their children should be happy even if it shortens their life; however, it must be doubted that children who are grossly overweight and being teased and finding it difficult to get around, are happier than those whose weight is kept under control. Unmanaged, life expectancy is almost certainly short (20-30 years); managed, it is considerably longer and there is every expectancy that many of the current people with PWS will eventually draw their pensions. The oldest person we know of was aged 71 years at death.

Locks on kitchen
doors and cupboards are used by some families to control the access which
the person with PWS has to food. Some people with PWS feel much more comfortable
with this arrangement since it takes the responsibility and continual temptation
away from them.
Digital locks are significantly more expensive but very much more convenient, since no key is required and every member of the family who is old enough to remember the code has access.

Lying seems to be

Marriage is a
goal for many people with PWS but for most may be unrealised. However, as
the present generation of young people with PWS advance into adulthood it
is goal which will need to be addressed. Parents may be frightened or reluctant
to face the issues of sexuality and marriage for their disabled child and
perhaps should be reminded that the idea of marriage may be for companionship
and belonging, not sex (since hormone deficiencies may mean that there is
little if any sex drive present).
Although we do know of one or two people with PWS who have married, they have not been able to have children. One woman with PWS publicly expressed her continuing regret and anger at being prevented from marrying her boyfriend who has since died. Legally, and surely morally, the adult with PWS is as entitled as any one else to enter into a contract of marriage, provided that they understand the nature of marriage and the responsibilities that go with it.

Memory in people
with PWS can be almost phenomenal. Cases have been known of people being
able to recall the route of a journey, many years after it had taken place.
Care must be taken, therefore, when giving instructions; what goes in tends
to stay in, and may be difficult to modify. [It isn't wise to argue with
someone with PWS about something which happened three years ago last Wednesday
- you will lose]. Long term memory for people and places is good; short term
memory for abstract concepts and instructions is much weaker, so that academic
memory in people with PWS can be poor, with what appears to have been learned
today, forgotten tomorrow.

temptation for people with PWS, since it is easily exchanged for food, and

undesirability of the person with PWS accumulating large sums in bank accounts,
which might ultimately affect state benefits to which they are entitled.

Nystagmus is
a complex condition which manifests itself in the form of involuntary movement
of the eyes, normally from side to side, which can seriously reduce vision.
Nystagmus has a number of causes and is usually a symptom of an underlying
problem in the neural pathways behind the eye.
The effects of Nystagmus vary from person to person but for many depth perception is reduced, leading to poor hand-eye co-ordination. People with Nystagmus may need more time to see and identify things: scanning ability is reduced which may slow reading speeds (perhaps requiring examination boards to allow extra time). Although many people with Nystagmus can read small print if they are close enough to it or use a visual aid, clear, large print should be provided.
The Nystagmus Action Group has a telephone Hotline on (01392) 72573.

Obsessive
Behaviour is part of the syndrome. Typical compulsive behaviours
include cutting paper into little pieces and doing jigsaws, word searches
etc. Obsession with time is possibly linked to poor short-term memory.
Perseveration (see below) is one form of obsessive behaviour. Obsessive behaviour
can be deflected by making a joke of the situation, or, where a particular
item is involved (e.g. a chair), playing a game like Musical Chairs, involving
that chair. Some parents pick up on each occasion when the word is used,
others set a time limit on discussion of a topic.

Oestrogen is
the female hormone, and artificial forms can be given to stimulate the onset
of periods, or to regularise their occurrence, which may help the young woman
with PWS to feel more normal. As people with PWS are looking forward to a
more normal lifespan, there is concern arising about the risk of osteoporosis
due to lack of natural oestrogen production and this may also be treated
with artificial oestrogen supplements.

Pain threshold in
people with PWS may be high and can mask acute physical symptoms of illness,
e.g. appendicitis. There have been reports of a person collapsing from a
burst stomach ulcer before mentioning pain and of another having a chicken
bone stuck horizontally in their throat and then complaining of "discomfiture".
The high pain threshold means that serious illness can be difficult to diagnose
and that there is a danger from using very hot water unsupervised. Pain and
temperature control are also controlled by the hypothalamus, and the degree
of damage to the hypothalamus will be reflected in the degree of irregularity
in these controls. Pain can be complained of as an attention seeking ploy.

Parties can be
a source of distress for people with PWS. Many will have enjoyed few if any
experiences of being invited to parties and yet they see their peers being
invited to parties regularly, further emphasising their separateness. When
invited to and attending parties, the sight of everyone else stuffing their
faces with clearly desirable foods, while the person with PWS nibbles their
carrot and low calorie yoghurt, may reinforce feelings of isolation and the
unfairness of life. One strategy is to allow the person with PWS small portions
of party food on the understanding that other meals that day will
be lower in calories to compensate.

Periods and the
onset of menstruation varies widely amongst women with PWS. In rare cases
this is early, but the vast majority do not experience periods until their
late teens or their twenties (one person is reported to have started periods
at the age of 35). Some women do not have periods at all. Even when menstruation
occurs, it is likely to be scanty and/or irregular. Oestrogen (above) can
be used to bring about the onset of menstruation. The absence of periods
indicates the possibility of low natural production of hormones and this
could put the person at risk of osteoporosis (above) in later life.

is easy to lose. It is easy for parents to focus on the 'can't dos' rather

Physical
Activities are unlikely to be popular with people with PWS.
Poor muscle tone is a feature of the syndrome and this, together with poor
co-ordination, can lead to physical problems and a dislike of physical
activities. However, physical activities burn calories and physical exercise
(see below) should be taken.
Return to Home Page |
Back to the Top |
Physical
Disabilities include hypotonia (poor muscle tone - see above),
poor balance and lack of co-ordination and, if overweight, lack of energy
and stamina. Shape of mouth and palate combined with the hypotonia can make
it difficult to eat certain foods, and this may need to be taken into
consideration when diet is drawn up. Many younger children find it difficult
to blow their nose.
Small hands and feet are common, due to lack of growth hormone. Typically, a woman with PWS will take a size 1-2 shoe, and a man a size 3-5 shoe. Minor abnormalities and differences in length of legs and feet are relatively common.
Return to Home Page |
Back to the Top |
Physical
Exercise is extremely important, even if it is not at the
same level as that experienced by other teenagers. It helps diet by burning
calories and improving muscle mass. Many young people with PWS have poor
balance, and find stairs difficult, therefore exercises on apparatus, like
wall bars, may be very difficult. Initially, start with activities they can
do and move on from there. Exercise bicycles are very useful, and this can
be done at home, even while watching TV, and exercise cycles can and do improve
balance. One girl, who was having difficulty learning to cycle aged 14 due
to problems with balance, learned to cycle in an afternoon after six months
using an exercise bicycle..
The difficulties can cause PE classes to be a focus for behavioural problems. An individual programme of aerobics, or exercising to music, may be one way of dealing with the problem. Suggested exercises for young people can be found in LR Greenswag and RC Alexander's Management of Prader-Willi Syndrome. These exercises use skateboards, which can be used to lie on, and shaped foam blocks, for rollovers. Help will be needed, and a reinforcer at the end, e.g. a star towards an agreed goal. Local fitness clubs offer a "trendy", fashionable way of taking exercise and the cardio-vascular equipment is particularly suitable. Exercise with weights should be avoided until growth is finished or unless approved by paediatrician or endocrinologist.
