Huntington’s disease
Description:
Huntington’s disease is a disorder that attacks the nervous system. It causes uncontrollable muscle movements and spasm. It also causes severe dementia until the death of the infected person.

Inheritance:
A person will inherit Huntington’s when they get the Huntingtin gene from there parents. There’s not a 100% chance that the child will inherit the disease its only a 50% chance they will receive it. There are also no carriers for this disease its either you have it or you don’t.




Symptoms:
The symptoms of Huntington’s don’t show up until the infected person in in there late teen or twenty’s. Some of the symptoms of this disease are memory loss, change in personality, uncontrollable twitching or muscle movements and severe dementia. Once the symptoms show there is very little time before the disease takes its course.

Diagnosis:
this disease is diagnosed by testing the DNA of the person who is thought to be infected. Once someone starts to show symptoms doctors and scientists would then look into their DNA for any mutations. The mutation for Huntington’s occurs on the gene IT-15, if this gene is mutated you have the disease.



Treatment:
There is no way to cure Huntington’s but the goal of the treatment is to slow down the progression of the disease and make it easier to live with. There are medications, such as dopamine, that reduce jittering. There is some evidence that Co-enzyme Q10 may slow down the disease but there is no proof.




Research:
Since there is no way to stop or slow the disease down doctors and scientists are doing tests on people with the disease to see if they can find a way to cure or at least slow the disease. At this moment there no solid cure in sight.





Additional Facts:
This disease attacks the nervous system and the mutation occurs on the IT-15 gene. It also causes severe dementia and depression. There are some medications to make it easier to deal with but none to stop it. Only one out of thirty-thousand people get this disease and it is mostly found in the United States. The disease was first described by Dr. George Huntington in 1872.
