Huntingtons+Disease

1. What is Huntington's Disease?
==Huntington's Disease is the declining of brain cells, called neurons, in a certain area of the brained causing uncontrollable movements, loss of intellectual facilities, and emotional disturbance. It is passed from the parent to the child, each child has a 50-50 chance of getting Huntington's Disease (HD). Anyone who inherits the disease will sooner or later develop the disease. Some symptoms of HD are mood swings, depression, irritability or trouble driving, learning things, remembering facts, and or making a decision.==

2. Is There a Treatment?
==Physicians prescribe a number of medications to control the emotional and movement problems. Tetrabenazine has been approved by many to cure the movement problems of HD. It is the first drug approved to be used in the US to treat the disease. It is very important for people with HD to maintain physical fitness, for those who tend to be more active do better than the ones who don't.==

==Huntington's Disease is a dominant inherited disease. That means that a person only has to inherit one of the genes from the parent to get HD. So people who have Huntington's disease have a 50% chance of passing it on the their child. A gene called huntingtin is just slight larger than the normal size. It is a result of an abnormal expansion of a repeated section in the DNA of the gene.==
