An undated old family portrait of the Reisweig family provided by Gary Reiswig is seen in New York July 13, 2011. Reisweig's family has a rare form of Alzheimer's disease that has stricken 10 of his 14 aunts and uncles shown in the photo, including Gary's father and his only brother and sister in the prime of their lives. The family has dominantly inherited Alzheimer's disease which is rare, and afflicts the young. In his family, symptoms can appear in the early 40s. Some 35.6 million people worldwide have Alzheimer's, the most common form of dementia. Drugs only help symptoms; none can arrest Alzheimer's, which costs $604 billion a year globally to treat.
