Huntington\u27s Disease and Its Effect on the Brain

Huntington\u27s disease is a neurodegenerative disease that leads to gradual extensive brain damage, especially in the striatum and the cerebral cortex. Initial symptoms are cognitive difficulties, loss of motor contra and sudden mood imbalances. Cognitive function slowly declines into dementia, coupled with behavioral and psychiatric problems. Sufferers die within 20 years due to illness complications: a fall, pneumonia, or heart disease (Walker, 2007). This paper reviews the principle biological cause of the disease, its effect on the brain, diagnosis, and treatment
