how long does the test for huntington's take to get results
Hi Jenny,
For the predictive test, this will depend on the genetic service that is doing your test, but it is usually approximately 4 – 6 weeks. This also allows time for the all the pre-result counselling and assessments to be done. Occasionally if the testing team is concerned about the person’s psychological state they may postpone the results until this has improved with treatment and further counselling. Most genetic services try to be flexible and not hold up the process unnecessarily. In most states it is a similar time frame for a diagnostic test, that is, if the person being tested already has symptoms and the test will determine whether HD is the cause of those symptoms.

What is the benefits on apply for life insurance before getting tested for the HD gene as opposed to afterwards?
Angela
Aged 21
Hi Angela,
This is a good question. When you apply for a life insurance, disability or income protection insurance policy you have to answer all the questions honestly. This will include questions about your family history of Huntington’s disease (or another genetic condition) and whether you have had a genetic test. If you have already had the test and it showed you do have the genetic fault that causes HD, you have to declare this when you apply. For most insurance companies this will mean that you won’t be offered an insurance policy. For an exception to this see the section on ‘Insurance’ in the 18+ section of this website. If you apply before you have the test you still have to declare your family history but you won’t be automatically denied a policy when you are at 50% or less risk. However you may have to pay higher premiums (monthly payments) because of your risk. For a more detailed explanation please check out the ‘Insurance’ section (to the left when you click on 18+) on this website.

My mother has the HD gene (early symptoms) and i find it hard 2 live with her as she is extremely emotionally detached. I live in the western/eastern syd suburbs and wanted 2 see a psycologist?
From Alex - Aged 20
Hi Alex,
It can be very difficult to live with someone who has the emotional changes that HD can cause. It is a good idea to find a psychologist for support with these issues. As you may already know there is a scheme you can access through your GP called a Mental Health Care Plan. The GP can refer you to a psychologist who is registered with this plan for Medicare and you can claim a rebate from Medicare for part of the cost of the sessions (up to 6 sessions initially or up to 12 if needed).
In the eastern suburbs of Sydney there is a psychologist, Sue Hawkins, who has the Medicare registration and also has experience with HD and genetic issues. You can find her contact details on www.suehawkins.com
Please contact us again if you have any further questions.

i have a low cag count of 38. But i already have HD. I thought i would have late onset HD because i have a low cag count. what has happened ?
Name: sally capel
Question: i have a low cag count of 38. But i already have HD. I thought i would have late onset HD because i have a low cag count. what has happened ?
For all people at risk of HD, the size of the CAG repeat is a major factor in determining the age at which symptoms appear. That is, the lower the CAG number the later the average age of onset. Conversely, the higher the CAG number the lower the average age of onset.
The key word here is average. To put it another way, if 100 people have a CAG number say of 38 then most will have an age of onset in their older years, but some people will still get HD at a younger age including a few in their 30's and 40's. For this reason, doctors and genetic counsellors can never tell you as an individual when the HD will appear.
The main significance of having a positive result is that one day you might get HD rather than telling you the age of onset. People with a CAG number of 36 to 39 have a less than 100% chance of getting HD and the average age of onset is higher than for people with 40 or more CAG repeats. If the CAG number is 40 or more then the life long chance of getting HD is effectively 100%, but again the age of onset will vary widely from early adulthood to old age.
The CAG number does not influence the initial symptoms of HD, as far as we know. That is, one person with a particular CAG number might first get chorea whereas another person with the same CAG number might develop anxiety & depression.
We don't know why there is so much variation in the age of onset or the initial symptoms. Probably there are other genes, most of which have not been found, that might have an influence on age of onset. Lifestyle might also be important. There is quite a lot of evidence that physical and mental activity in general might delay onset of HD. Physical and mental activity is also fun and is good for health in other ways like keeping your weight down & protecting you from diabetes and high blood pressure. I recommend to my gene positive patients that they exercise for about 20 or 30 minutes three times a week and keep their minds active.

my dad has huntingtons disease and my grandad did and do did his dad, does this mean it only gets passed on through the males in my family or do i still have a chance if im a girl?
Name: Kirsten
Age: 15
Question: my dad has huntingtons disease and my grandad did and do did his dad, does this mean it only gets passed on through the males in my family or do i still have a chance if im a girl?
Huntington's Disease is inherited in an autosomal dominant fashion. This means that each child of a person carrying the HD gene has a 1 in 2 or 50% chance of inheriting the gene. Men and women are equally likely to inherit the gene.
The fact that your dad, grandfather & great grandfather all had HD is a fluke. That is, the women of the family have been lucky. You are at a 1 in 2 risk of inheriting the gene from your dad. So are your brothers & sisters. If you or one of your brothers & sisters has the gene all the otters are still at a 1 in 2 risk of inheriting the gene also. That is, the 1 in 2 risk applies to each child regardless of the gene status of other family members.
My mother, elder brother and younger sister all had or have huntingtons. As I am 52 and show no signs can I presume I am free of the desease?
The only way to be certain of your gene status and hence whether or not you might one day get HD is to have the gene test. As someone with first degree relatives with HD you are at a 1 in 2 or 50% statistical risk of inheriting the gene. Most people who are gene positive develop symptoms by their early 50's, but some get symptoms in their older years. We don't really understand why there is so much variation in the age of onset
Andrew
Does HD usually occur earlier in the next generation if the mother is the carrier of the gene?
Susie Aged 65
Typically people with the Huntington's Disease (HD) gene get symptoms from late 30s to mid-50s, although any age of onset is possible from childhood to old age. The size of the CAG repeat count does not reliably predict the age of onset in most cases.

Could you please clarify the question? Who in the family (e.g. grandparent, uncle, aunt, parent, etc) is gene positive for HD?
Do fraternal/identical twins still have a 50/50 chance of testing positive for HD - or is it a case of if one has it, the other definitely will too?
Name: Jacob
Age: 16
Question: Do fraternal/identical twins still have a 50/50 chance of testing positive for HD - or is it a case of if one has it, the other definitely will too?
If twins are TRULY identical, then if one is gene positive the other will have the gene also.
If twins are non-identical, then each twin is at an independent 50/50 risk of inheriting the gene. That is, one could have a different gene test result than the other. For example, one might be gene positive & the other gene negative. It might also be the case that both might be gene positive but have different sized CAG repeat expansions. Both might of course be gene negative.
In terms of predictive testing, if one member of an identical twin pair tested positive for HD then I would recommend that the other considered getting counselling to help them work out what the result might mean to him or her.
There has been one case, of Australian identical twins, who presented differently. That is, identical twins cannot assume that HD will behave in exactly the same way in both twins. Also, the psychological impact of being gene positive might be different in each twin. These subtleties are why I'd recommend that the second identical twin might see a counsellor

I know that people who suffer from HD have a shorter life expectancy. I just don't know why that is ... what do they die from, exactly? How long do you have, from the onset of symptoms?
Rachel (18) has just sent in a question.
Name: Rachel
Age: 18
Question: I know that people who suffer from HD have a shorter life expectancy. I just don't know why that is ... what do they die from, exactly? How long do you have, from the onset of symptoms?
The answer to these 2 questions are not as straight forward as they might seem.
In general people with HD become very disabled at about 10-15 years from the onset of symptoms. However, the rate of progression is very variable and so some people become very disabled well before this & some many years later. I general, the older a person is when they get symptoms the slower the disease progression. Thus, people who first get HD symptoms in old age (say over 65) might have a normal life expectancy. However, since most people get symptoms when they are younger than this for most people life expectancy is reduced.
In my experience, the commonest causes of death are pneumonia and trauma from falling.
Pneumonia can occur when the wallowing muscles become weak & so saliva, fluids & food can trickle into the lungs and cause an infection. This is why it’s important that people with HD see a speech pathologist and when needed their diet is modified. For example, fluids can be thickened & food cut up finely or minced. Changing the diet this way reduces the risk of chest infections & allows the person with HD to get enough nutrition.
Falls are common in HD & can be very heavy. This can result in severe injuries like a broken leg or a fractured skull.
The other major cause of death in HD is suicide. This is a very upsetting thing for families, and for doctors & nurses. There is a lot we can do to help people who are suicidal to get rid of these awful thoughts and make them happy & safe again. Anyone who feels that they might want to harm themself or who has a relative who they think might be suicidal should go to their doctor or ring Lifeline or their local Huntington’s Association to get help. Everyone who looks after HD families is happy to help an individual in distress.

Why do I have to wait months to get a test to tell me I may have HD
Jamie (30) has just sent in a question.
Name: Jamie
Age: 30
Question: Why do I have to wait months to get a test to tell me I may have HD and with that limited time. Two months for first appointment,upto three for second and again for the third for testing?
Hi Jamie, thanks for your question. Yes I know the waiting times for testing can be frustrating, and they vary between genetic services depending on how booked up their appointments are. It is recommended as part of the international protocol for predictive testing for HD that there is some time between the first and second appointments, to allow further time for thinking about the decision, perhaps seeing a private counsellor, and in some cases, to organise things like life or income protection insurance. Having said that I think there should be some flexibility within the protocol to adapt to each person and their circumstances. At the first appointment it would be worth trying to see if you can negotiate a shorter waiting time, based on your age and preparedness for the test, and any other factors you think may be relevant. The decision to have the test carries enough stress without the added stress of imposed time frames. Hopefully the professionals you are seeing will be open to discussing these issues with you.

Age: 26
Question: If HD runs in our family but my mother doesn't have the gene do i have a chance of being a carrier of the gene?
Hi woomill,
No if your parent is gene negative (doesnt have the gene) then you will also be gene negative (not carry the gene)
If a parent is gene positive (they carry the gene) then the child has a 50% chance of also having the gene.
My boyfriends mum died of hd at around 40, I was just wondering as it seems to be a trend in the family that only the women have recieved it is it possible that there is a trend?
HD is an autosomal dominant genetic disorder. That is, each child or sibling (brother or sister) of someone with HD has a one in two or 50:50 risk of inheriting the gene. What this means is that if someone with HD has 10 children then on average 5 will inherit the gene and 5 won’t. However, there will be some families where less than half of the children will inherit the gene and some others where more than half of the children will inherit the gene.
Men and women are at equal risk of inheriting the gene.
The only certain way to know of if someone has the gene is to have a gene test.
If most of those in a particular family who get HD are women then this is just bad luck for them and good luck for the men of the family. If your boyfriend’s mum had HD then he is at a one in two or 50:50 risk of inheriting the gene even though he’s a man.

Hi. my boyfriends mum has got hd but he is adament he doesn't want to get tested but i have a baby with him..is there any way i can find out if my baby has got it or not?

Name: Stacey
Age: 19
Question: Hi. my boyfriends mum has got hd but he is adament he doesn't want to get tested but i have a baby with him..is there any way i can find out if my baby has got it or not?
Hi Stacey,
Thanks for your question. Firstly, regarding your boyfriend’s decision not to be tested, the majority of people at risk choose not to be tested, mainly because they are worried about the emotional effects if the test result predicts that they will develop HD, and there is still no treatment to prevent it. It is a very personal decision and it is good to support whatever decision an at risk person makes with regard to testing. I assume that your boyfriend is still young so hopefully with all the research (including trialling treatments) that is going on worldwide an effective treatment will eventually be found. This will change most people’s decision about not being tested, as it is a different matter if something can be done to prevent HD developing. This will also make a difference to the situation regarding testing of children. At the moment, as there is no preventive treatment, there is a worldwide agreement not to test children at parent’s request. As most adults decide not to be tested, it is also important to preserve the child’s right to make his or her own decision about being tested, when they are old enough to comprehend the implications of this decision (usually 18 or older). In your situation another problem would be that if your child is tested and found to have the HD gene change, this would also be the result for your boyfriend, which he doesn’t want to know. This would be an extremely difficult ‘double whammy’ situation to handle, so it is best to leave things as they are, and try to live with the uncertainty, which I know is difficult. At the moment your child has a 25 % chance of having the HD gene, which also means a 75% chance of not having the HD gene. It is also difficult to believe that there will not be substantial improvements in treatment for HD, and hopefully even a prevention or cure, by the time your child reaches the age when most people develop HD (late 30s – mid 40s).
If you would like to discuss your situation with a genetic counsellor you could contact the HD Association in your state to find out the contact details for your nearest genetic counselling service.

My partner is 28, and has recently began severe twitching and strong jerking movements as he is drifting off to sleep (the only time this is evident), i have convinced myself these are HD symptoms? Are there benefits in early diagnosis? He has not tested
Jessica - 28 years old
This question raises a number of important issues .I will answer them in point form for the sake of clarity:
1) Leg twitches & jerks when someone at risk of HD drifts in or out of sleep: Although this could be chorea, it is much more likely to be a normal variant. People often twitch, sometimes quite violently when they drift in or out of sleep. However, to be certain of this it would be best to be assessed by a doctor
2) When to get genetic testing: The only good time to have predictive testing for HD is when the at risk person is ready for it. This is a very individual thing and it also has massive implications for partners. Working out what to do & when to do it is very stressful. In my experience one of the times when a person at risk of HD might want testing is when they are planning to have a family. If you as a couple are considering PGD then you have 2 options. Firstly, your partner could have gene testing and if he is found to be gene positive then consider PGD. Secondly, if he doesn’t want to have gene testing, but you are not willing to have gene positive child then you can still use PGD. These are obviously very difficult & complex issues. One option might be for you and your partner to see us at the Predictive Gene testing clinic, not for gene testing, but to have a talk about the issues which you face & to get the information which need. We often have people in your situation ringing to get advice or coming to see us for advice, but without any requirement to have gene testing.
All the best for the future
I am interested in knowing more about getting life/funeral insurance. I read online as part of this website that Virgin money is offering a "quick and easy option" and that one of your representatives made contact to confirm this includes people at risk o
Deb (29)
Hi Debbie
Thanks for your question! Having a parent with HD doesn't qualify you as having a pre existing medical condition but life insurance companies will also ask questions about family medical history which require's you to state information about HD and then they use it as a reason not to insure. This is why pre-symptomatic people have had so much trouble. The reason we are excited about the Virgin quick and easy option as is that it appears to be the first product that does NOT ask you any questions about anything related to HD or your family, so you can get life insurance. Regarding your question about the definition of accident, I can see why you are concerned, but your question is really technical and either the insurance companies themselves or perhaps your own legal advice would be the best place for more info?
Cheers, Tony and the HD Space team
I am wondering whether l should be tested for HD. My grandmother had HD, my mother has been tested and has CAG repeat of 39, which l understand places her in the gray area. So basically l am wondering where this places myself.
Bron age 35
Bron is at a 1 in 2 risk of inheriting the HD gene from her mum. Your mum’s CAG repeat number is in the grey zone. If you inherit the HD gene then you are also likely to have 39 CAG repeats.
Whether you want to be tested for the HD depends on you & your needs. Everyone is different.
It’s important to remember that if you have inherited the gene then you could still get symptoms of HD. People with a CAG repeat in the grey zone have a less than 100% chance of having symptoms & often they get HD well into adulthood.

Hi Meaghan,
I'm sorry to hear about your friend - is she a similar age to you? If so that is very
young to have HD. I think the best things you can do are to learn as much as you can
about HD (from the internet/websites like this one, and from your local HD Association)
and to listen to any problems or concerns your friend may want to talk about. You can
encourage her to get medical help (if she doesn't have this already) - again your local
HD Association will give you the contact details for the nearest HD specialist and
team. You can also help her in practical ways if she needs it, like helping with her
shopping, reminding her about paying her bills etc. Just being a friend, going out for
coffee and spending time with her is also very important. The HD Association can send
you a booklet about the ways HD can affect a person's thinking and behaviour, so you
know why she may be behaving in certain ways due to the illness. For example, people
with HD often have trouble remembering day to day things like appointments and paying
bills, and have trouble planning things they need to do, and carrying out a plan. So
they often need reminding of things (in a nice way of course!).
I hope this information is helpful but if you have any other questions please ask!

Hi Kathy,
It sounds like you are dealing with a very difficult situation for the whole family and
particularly for your mother. It is definitely a situation for which you need
professional assistance, preferably from a specialised HD service. There may be
medication that can modify your father's abusive behaviour, and a specialist and social
worker may be able to arrange some residential respite care to give your mother a break
and to do a thorough assessment of your father's behaviour and moods. Sometimes it
takes a bit of trial and error to get something that works, which is frustrating for
all concerned. If you are already in contact with an HD service I would encourage you
to let them know of this latest development. But if you are not linked to an HD service
you need to contact the HD Association in your state and ask who you can be referred to
for assistance.
I hope this is of some help.

Question: Is shaking in the hands a symptom? What if it is shown as early as my age?
Shaking in the hands is not usually seen in Huntington's Disease, but is seen in many
other conditions. Some of these are very common. If you are concerned then you should
see your family doctor (general practitioner)for a check up and advice. Also,
Huntington's Disease is very rare at 19 which makes another cause of the tremor unlikely

my dad has hd and i asked th school counselor if there was anyone else that has a parent with hd but she said that i was the only one! i have no idea what to tell my friends because they don't know about my dad. what should i do?!
Hi Regan, I'm sorry this answer has taken a long time but I have been away. I think you
could start by telling your friends that your Dad is not well, and that he has an
illness that affects his brain, which causes parts of his body and his mind not to work
properly. You would need to say that there is no cure for the illness and that it gets
worse slowly, but that some of the symptoms can be treated with medications to keep him
as good as possible. You can say that he will need a lot of looking after, from both
the family and from special carers that can come and help him at home. If you feel
confident you can tell them it is a genetic illness, caused by a mistake in one gene,
which he would have got from one of his parents.
Two other things you can do are to give your friends the website address for OurHDSpace
and then they can look up the information they want to on that. Also you can contact
the HD Association in the state where you live (the phone numbers are on the website)
and ask them to send you some written information (in NSW there is a booklet called
'Fact Sheet for Teenagers' which explains HD in plain English and not too many words),
which you can give to friends to read.
I hope this information is helpful. If not let us know and we will try to help further.

getting geneticly tested
Sarah (25) has just sent in a question.
Name: Sarah
Age: 25
Question: Hi! I am thinking about getting geneticly tested (my mum has huntingtons disease). I don't know if I should tell my mum though. She is currently displaying symptoms of the disease and when I hypothetically asked her what she would think if I decided to get tested, becuase I'm getting to the age of thinking about starting a family, she said I was too young and started saying ridiculous statements that didn't make any sense- about how I could just genetically test my child and not me. She did say she would want to know I was doing the test though. I don't know what I should do, to tell my mum I'm going to do the test or not. I'm worried she will break down if it's positive and I'm not sure if she can take it emotionally, because I'm not sure if her thinking is 100%, but is it morally wrong if I don't tel her and I have to live with the guilt of decieving her. This is hard because I've grown up with HD my whole life but it is never talked about, it's almost something that has become shameful, which is sad. I'm worried how my result will impact my immediate family, especially my mum. Sorry this is so long! Thank you.
Hi Sarah, this is a difficult issue that a lot of people at risk struggle with when
they are thinking of having the predictive test, whether to tell their parent who has
HD. It is understandable to not want to add stress and worry to a parent, either while
waiting for the result or, as you say, if it is positive. It is not morally wrong to
not tell your parent, because who you tell is completely your decision, and you are
only trying to protect her. On the other hand being open about it can allow you to
receive support, and parents (even with HD) are often stronger than you think. The fact
that your Mum has said she would want to know perhaps indicates that she would be OK.
Regardless of whether you decide to tell her, it is recommended to tell someone in the
family, or a friend, so you have support during the testing. It is not a good idea to
do the test without telling anyone. Regarding telling a parent with HD. obviously there
are pros and cons whichever way, and it would be good to see a genetic counsellor or
social worker in your area who specialises in HD/predictive testing, for a discussion
and counselling on this and other issues, before going ahead with the test.
By the way your Mum was sort of correct when she said you can get your (unborn) child
tested without being tested yourself. There is a technique, called PGD exclusion
testing, which can be done using IVF and preimplantation genetic diagnosis (PGD) in
which the embryos are created, then tested NOT for the HD gene, but for the chromosome
4 markers that can distinguish which side of the family (on your side) the chromosome 4
has come from. It would require a blood sample from (ideally) both of your parents, as
well as you and your partner. Any embryos that have a chromosome 4 from your Mum's side
of the family would be excluded ie not used to start a pregnancy, as there is a 50%
chance that that chromosome has the HD gene. So that way you can be confident that the
child will not have the HD gene, while not having to find out whether you have the HD
gene. You can get more information about the PGD process from the website of Sydney IVF
- www.sydneyivf.com
I hope this information is helpful and I would encourage you to contact your local
genetic counselling service for help to sort out your dilemma.

Fiona

how can you tell if your clumsiness and forgetfulness are a symptom to the disease or just personality traits that might have been picked up between parent and child?
From Tam Aged 24
This is a very difficult issue for people living with the risk of Huntington’s disease (HD). In my experience most people at risk of HD worry about whether or not they have symptoms. On occasions they can get very stressed about concerns that they might have symptoms.
The commonest cause of forgetfulness is not dementia or HD, but anxiety & stress. Sleep deprivation is also a common cause of forgetfulness. The forgetfulness in both cases is due to poor concentration and attention which results in difficulty in focussing. Living with HD is stressful and that stress might be enough to make you forgetful.
Clumsiness is common (the doctor writing to you has it in spades and he doesn’t come from a HD family). If you don’t have definite chorea (twitching involuntary movements) then the risk of clumsiness being due to HD is low.
Tam, I gather that you are 24 years old. HD can occur at any age, but most people don’t get symptoms until they are in their late 30’s or older. That is, the chance s of you having symptoms of HD aren’t zero, but they’re very low. If you’re really worried then you should see your GP to talk about what to do. Sometimes the best way to handle worries like this is to get a check up & have the chance to get expert advice.

what is considered a high cag repeat number
Asked by Jill who is 16 years old.
If the CAG repeat number is 40 or more, then one day the person will get symptomatic Huntington’s disease (HD). The typical age of onset is from late thirties to mid-fifties. In general, the higher the CAG repeat number the earlier the age of onset.
If the CAG repeat number is between 36 and 39, then there is a less than 100% chance that the person will develop HD and the age of onset of symptoms is often in the sixties or seventies or even older.
It’s important to remember that the exact repeat number doesn’t reliably predict either the age of onset or the symptoms a person might get. That is, no doctor or genetic counsellor will be able to tell a gene positive person when she or he will get symptoms.
It’s difficult to say what is and what is not a high CAG repeat number given that it doesn’t reliably predict when HD will appear or how it will behave. I guess most doctors would say that if the CAG number was above 50 then that was high. However, if someone does have a CAG repeat number like that then it doesn’t mean that they will inevitably get HD early.

I suggest that you start with whoever made the diagnosis – was it a paediatric neurologist, and was it in a children’s hospital? If so you can ask if there is a social worker you could speak with, who could help you make a plan for your daughter’s care. You could also contact the HD Association in your state and ask what services are available for you and your family. A children’s hospital or HD service should be able to connect you with a team of professionals who can help at various stages, such as a speech pathologist, dietitian, physiotherapist and occupational therapist. Your granddaughter’s neurologist should also be able to prescribe various medications that can help with some of the symptoms. You can also use the HD Australia forum – www.hdaustralia.org - to learn from other families who have dealt with juvenile HD. There is also a website based in England that might provide some good information and support –www.jhdfamilies.co.uk – as you will certainly need support for yourself as a carer. But the most important thing is to find local professionals who have some knowledge of HD and juvenile HD who can get to know your family and support you along the way with whatever you may need. Please let us know if you have any problems finding this support.’
My dad and brother have HD, I havent had the test done yet, but if i was to test myself and it comes out negative would it end there or will my children be at risk?

If you are gene negative then you cannot get Huntington’s disease and you can’t pass it onto your children. That is, if a person is gene negative then all their descendents are safe.
Each person has one in two (50%) risk of inheriting the gene from a gene +ve person. That is, you have a 50% risk of inheriting the gene, regardless of the fact that your brother has HD

Is there anyway of knowing if someone is faking having HD?

Question: Is there anyway of knowing if someone is faking having HD?
This is a very, very difficult question to answer. There are a number of reasons why this is so.
Firstly, the major symptoms of HD (chorea, anxiety/depression & memory problems) are non-specific and occur in lots of other conditions and also in people who do not have a neurological disease. In particular, anxiety & depression are very common throughout the community. It is thought that up to 30% of adults at any one time have significant anxiety or depression. It can also be very difficult to pick early HD from alcohol abuse or heavy marijuana use.
Secondly, there is no scientific consensus as to how to diagnose early HD and it is now realised that emotional or cognitive symptoms can precede the onset of chorea by years.
I have never met anyone who I have felt is faking HD. However, I have seen people who have genuinely believed they have had HD when they haven’t. Most times this occurs because they are anxious or depressed for another reason and have then assumed that they must have HD.
Much more commonly, we see people with definite symptoms of HD who are in a state of denial. This can be very difficult for families & carers, but generally it is still possible to help the patient and his or family.
If there is a possibility that someone might have HD then it is probably best that they see an expert on the disease.
It is also very, very important to recognise that being gene positive for HD is not the same as having HD. People are born with the gene, but rarely get symptoms until well into adult hood. Why it takes decades for the gene to cause brain damage & then symptoms is unknown. However it may be that regular physical exertion and mental activity delays the onset of symptoms. That is, being a couch potato is not a good lifestyle for those at risk of HD. Regular exercise is also fun and has lots of other health benefits.

I am getting tested next month for HD. I have no symptoms but I am ready to start a family, so it is crucial to know. I just got married last month. My question is what kind of life insurance do I get. There is such a big debate between whole and term. I
the other day i was looking on the internet and found out that there are natural minerals that HD patients are missing how come the doc's don't give them the minerals
Asked by jill (16)
Jill,
To my knowledge there are no mineral deficiencies in HD. Could you send me more information?
Andrew Churchyard
Jill,
Just wondering if what you were reading may have been in regards to vitamins/suppliments?
Cheers

Please ask another question if you need more help

Asked by Jessica (18)
Jessica there are Genetic Counsellors who you can contact in regards to testing. Here are a few contacts below. They will be able to steer you in the right direction, depending on where you live.

Asked by Meg (15)
I'm considering being tested for HD but need to sort out my life insurance first. Is there any insurance companies that you recomend?
Asked by Tom, Aged 26.
I'm considering being tested for HD but need to sort out my life insurance first. Is there any insurance companies that you recomend. I have been struggling to find one that will insure me because my father past away from HD. Any help would be much appreciated.
Hi Tom
To try to obtain life insurance, disability insurance or income protection insurance when at 50% risk it is best to go through an insurance broker who can try to secure the best policy, rather than contacting separate insurance companies one after another. The broker we recommend is called Special Risk Managers - telephone 1300 665 356.
Cheers Fiona
Further to Fiona's response Tom, if you have a read of the 18+ section under Insurance there is some info regarding Insurance companies and how we think you should respond regarding testing questions. Also, if asked whether you are planning to be tested for HD, it is best not to answer 'yes' to this question as then the broker/company will want to postpone offering a policy until you are tested and know the result. However the reason for obtaining insurance PRIOR to being tested is that you will not be able to get this type of insurance if you test positive. It is best to answer 'not sure' or 'not at this time' or something similar. IT IS AN UNFAIR QUESTION ANYWAY as people at risk chop and change their minds on this, so an answer one day is not necessarily valid for the next day. (The Our HD Space team)
My sister is gene positive with a repeat count of 39. I understand this as being a low number. If i test positive as well will my number be similar or are they totally unrelated?
Asked By Ross, 38
The answer to this question depends, to some degree, on who was the gene positive parent. That is, the answer will be a little complicated.
If Ross inherits the gene (a 50% or 1 in 2 chance) then most likely he will have the same or very similar repeat count as his sister.
However, if inheritance is from the father, there is a small chance the repeat number will increase whereas this is less likely if inheritance is from the mother.
It is also important to remember that if the repeat number is less than 40 then the average age of onset of symptoms will be greater than if the repeat count was 40 or more. There will also be a less than 100% chance of developing symptoms of HD

i want to help with trying to find a cure for hd. altho my grades are not great and im not shure i will be able to get a doctor dagree. can i still help
Asked by Kyle aged 15
There is heaps you can do to try to find a cure Kyle! Doctors and Scientists need money to pay for their research. They wont find a cure without it. You can help by raising awareness of HD and even perhaps raise some money that you can give to the scientists to help find a cure. Have a read of our 'take action' part of the site for some ideas. You could hold a sausage sizzle or a casual clothes day at school for a gold coin donation. Check out this guy www.hoopathon.com in the USA. BJ started this when he was about 10 years old with his family.

My friends say my nanna is weird...i dont think she is weird, she is my nanna...but i feel embarrased sometimes, what do i do?
Asked by Kirri aged 10
When people have Huntington's disease they behave differently from other people - they may walk or talk in a different way, they may have funny jerky movements and find it difficult to sit quietly. People who don't understand that the person has an illness may laugh or tease you. You need to tell them that your nanna has an illness that affects her brain and that is why she is different, and she can't help being the way she is.
