Give a detailed description of the Huntington disease.
Huntington’s Disease (HD) is a genetic disease of the nervous system in which the nerve cells in the brain start degrading. It is hereditary and this means it is transmitted from a person who is the carrier of the defected gene to his children.
The disease is severe in nature but often remains undetectable during the early stages of life. In fact, most affected persons show clear symptoms of this disease after mid-40s. Some typical symptoms are loss of thinking or cognitive powers, general incapacity of body balance (hence, problems with walking), psychological disturbance, loss of memory and identification abilities etc. Depression is common in such patients and so this gives rise to a disturbed social life. Centers for special type of counseling for such people are also available.
The genetic science has advanced to the level that we can detect the disease in much earlier stages, even before the primary symptoms become evident. But, unfortunately there is no cure for the disease as of now, and all people suffering from this disease die after the symptoms reach an advanced stage.
