Huntington disease is an inherited disease and affects the brain. You have a 50% of chance of this disease, if one of your parent has this disease. It is caused by mutation in a gene on chromosome four. A blood test will help you in the recognition of this disease. It results from degeneration of neuron nerve cells. This affects the cells in basal ganglia of brain.  This portion of brain controls cognitive ability, emotion and movement. The symptoms include difficulty in walking, speaking, swallowing, muscle co-ordination and poor memory. It also affects the outer surface of brain.
