The Inheritance (2014)

This haunting, personal film offers a firsthand perspective on the hereditary neurodegenerative Huntington’s Disease. The condition typically shows up in mid-adult life, and DNA testing has shown Wellington film editor and screenwriter Bridget Lyon is likely to fall prey. She and her husband, director Jeff McDonald, are forced to face the disease’s horrors head-on while watching her mother’s deterioration.

Unfortunately the movie The Inheritance is not yet available on HBO Max.
