Huntington’s disease is an inherited disease that causes degeneration of brain cells. According to Mayo Clinic, “Huntington’s disease is caused by an inherited defect in a single gene”.
It usually starts showing symptoms during someone’s 30s or 40s, but it can also appear around 20 years old when it’s called juvenile Huntington’s disease.
The damaged brain cells can easily affect one’s everyday life because of the variety of symptoms. It can cause serious movement disorders, like muscle contractures, uncontrolled eye movements, difficulty speaking, but also cognitive and psychiatric disorders.
People with Huntington’s disease might have problems learning new information, difficulty organizing, lack of awareness. They might also suffer from fatigue, insomnia, and irritability.
