Young People affected by Huntington’s Disease



What causes Huntington’s Disease?
Huntington’s Disease affects a person’s brain, caused by a fault in a specific part of that person’s DNA. DNA is like a book of instructions for your body on how to function; each specific instruction is called a gene. There is one gene, called the huntingtin gene, which everyone has, but in people that develop HD their particular instruction has been written down wrong, so it is not carried out properly. So in a person with the faulty huntingtin gene, their cells function incorrectly, especially their brain cells, which is why they experience lots of different symptoms.

HD is hereditary which means that each child of someone who has HD has a 50% chance of also getting HD. People can get HD at any age, but it usually happens in people between the age of 30 and 50 years old.

What are the symptoms of HD?
There are three main types of symptoms that people with HD get. 
1) Symptoms that affect their movements, for example they have involuntary movements and problems with balance and walking.
2) Symptoms that affect their thinking and memory
3) Symptoms that affect their behavior, for example making them angry or sad, or making them act a certain way that isn’t how they usually act.

Every HD patient experiences different symptoms, some worse than others, and all starting at different times. 

What treatments are available for HD?
There is currently no cure for HD, but scientists all over the world are working hard to try and find one. There are some treatments for certain symptoms of HD, for example medication to help with their movement symptoms, or to improve their mood.
