Condensed from Huntington's Disease: Hope Through Research Huntington's disease (HD) results from genetically programmed degeneration of brain cells, called neurons, in certain areas of the brain. This degeneration causes uncontrolled movements, loss of intellectual faculties, and emotional disturbance. HD is a familial disease, passed from parent to child through a mutation in the normal gene.
Huntington's disease is an inherited disease of the brain. There is no cure, but much can be done to help families. The disease damages some of the nerve cells in the brain, causing deterioration and gradual loss of function of areas of the brain. This affects movement, cognition (perception, awareness, thinking, judgement) and behaviour.
