Watch Twitch (2014) : Full Movie Online Free Twitch follows 18-year-old Kristen Powers as she undergoes genetic testing for the disease that killed her mother. Huntington’s Disease (HD), a neurodegenerative brain disorder, destroys an individual’s ability to walk, talk, think, and reason, eventually leading to death. The film will chronicle the emotional, social and medical journey through this important test, as well as the impact it has on an individual’s future. Twitch explores the science with major Huntington’s Disease experts and activists who will provide deeper insight into the complexities and hopes buried in the disease. Huntington’s has great stigma surrounding it; solving its mystery could potentially lead to the cures of not only HD but also several other neurological illnesses such as Parkinson’s, Alzheimers and ALS. This documentary will highlight the pressures people, especially young adults, face when given the chance to be handed their medical fate.
