Parkinson’s is one of the most common—and destructive—neurodegenerative diseases in the world. In the United States, more than a million people will be diagnosed with the disorder each year, resulting in the loss of motor functions, cognition and memory. In a study published in Nature Medicine, principal investigator at MIT Jameel Clinic Dina Katabi and her fellow researchers trained an AI bot to observe and analyse a sleeping patient’s breathing patterns to detect neurodegenerative disease. The bot can also detect how severe a person’s Parkinson’s is, allowing doctors to tailor treatments to a person’s needs.
