Huntington's disease

Huntington’s disease is a fatal genetic disorder that causes deterioration of a person’s physical and mental abilities during their prime working years and has no cure. Several women convicted in the Salem Witch Trials were suspected of witchcraft due to symptoms of Huntington's disease. In 2002, a woman named Carol Carr killed her two adult sons in a nursing home after she couldn't see them suffer from Huntington's disease anymore. She was sentenced to 5 years and she served 2. After release, she was told if her third son started developing symptoms she was barred from being his caregiver. A year later he was diagnosed and she had to watch her only child suffer from a distance, unable to help him.
