What is Huntington's disease?

1. A viral infection

2. A genetic brain disorder

3. A form of autism

4. A type of intellectual disability

The correct answer is: A genetic brain disorder

Huntington's disease is classified as a genetic brain disorder that is characterized by the progressive degeneration of nerve cells in the brain. This deterioration affects various functions such as movement, cognition, and emotional control. The disease is hereditary, meaning it is passed down through families and is caused by a mutation in the HTT gene, which leads to the production of an abnormal protein that gradually causes neuronal cell death. Individuals with Huntington's often experience symptoms such as involuntary movements, loss of coordination, cognitive decline, and psychiatric issues, which typically emerge in mid-adulthood. Understanding Huntington's disease as a genetic condition highlights the importance of family history and the role of genetic testing when assessing risk for future generations. This comprehension is crucial for rehabilitation counselors, who must effectively support clients dealing with the implications of this hereditary condition.
