What is this condition?
Huntington's disease is a hereditary disease in degeneration of the brain Which cortex and basal ganglia causes chronic progressive chorea (involuntary Movements) and Mental Deterioration, ending in dementia. Usually Huntington's disease strikes persons ages Between 25 and 55 (the average age is 35), however, 2% of cases in children OCCUR, and 5% as late as age 60. Usually death results 10 to 15 years after onset, from suicide, congestive heart failure, or pneumonia.
What Causes it?
The cause of Huntington's disease is unknown. Because this disease is a genetic trait Transmitted as common to men and women, Either sex can transmit and inherit it. Each child of a parent With This disease has a 50% chance of Inheriting it, however, the child Who does not inherit it can not pass it on to his or her own children.

Huntington's disease can be detected by positron emission tomography and DNA analysis.Diagnosis is based on a characteristic clinical history: progressive chorea and dementia, early onset in middle age (35 to 40), and confirmation of a genetic link. Computed tomography scan (Commonly Called a CAT scan) and magnetic resonance imaging (MRI Commonly Called an) Demonstrate brain atrophy. Molecular genetics may detect the gene for Huntington's disease in people while they're still at-risk symptom-free.
How is it Treated?
