What is Ηuntingtons Disease
Huntington's disease (HD) is a genetic disorder, a nerve disease that affects the nervous system causing it to degenerate. This has an immediate effect on muscle coordination which leads to psychiatric problems. The disorder usually appears in mid-adult life, between 35 and 44 years of age
Ηuntington Disease Symptoms
The most common symptoms linked to this nervous system disease are changes in behavior (irritability, paranoia etc), abnormal movements (fast, sudden, sometimes wild jerking movements mainly of the arms, legs and face and sometimes of other body parts) and finally progressing dementia (memory and judgment loss etc). In most cases changes in the person’s behavior occur before the deterioration in movement. The disease can affect both men and women, because it is characterized as an autosomal dominant mutation (chromosome 4). If one of the parents has Huntington disease, their offspring have a 50% chance of inheriting the defective gene. If a child gets the gene from both his or her parents, they will have the disease at some point in their life. And they will also pass it on to the next generation.
Huntingtons Disease Treatment
Unfortunately, there is no cure for Huntingtons at the time being. The only thing doctors can do is to slow down the development of the symptoms for as long as possible.
Therefore, preimplantation genetic diagnosis seems to be the only way to prevent this disease from passing on to the next generation.
