By the time Alzheimer disease (AD) has reached its end stage, the brain is riddled with plaques, tangles, cavities, and fissures and has lost a substantial percentage of its weight. However, most people living with AD are not yet at this stage and still have a good portion of working neurons with which they can learn, be creative, and enjoy life, said John Zeisel, PhD, a sociologist who focuses on the therapeutic effects of residential environment design among patients with the disorder (Zeisel J et al. Gerontologist. 2003;43:697-711).
