Expert Video - What are the stages of Alzheimer's disease?

Richard Isaacson, MD, directs the Alzheimer's Prevention Clinic at Weill Cornell Medicine and NewYork-Presbyterian Hospital. In this video, he explains the stages of progressive brain decline in Alzheimer's disease from pre-clinical through mild cognitive impairment (MCI) to Alzheimer's dementia, including its phases. He discusses how cognitive function changes at each stage and how the stage of Alzheimer's disease someone has will determine the care and treatment they need.
