Alzheimer's disease (AD), one form of dementia, is a progressive, degenerative brain disease. It affects memory, thinking, and behavior. Memory impairment is a necessary feature for the diagnosis of this or any type of dementia. Change in one of the following areas must also be present: language, decision-making ability, judgment, attention, and other areas of mental function and personality. The rate of progression is different for each person. If AD develops rapidly, it is likely to continue to progress rapidly. If it has been slow to progress, it will likely continue on a slow course.

Is it possible for paranoid schizophrenia to appear late in life? A 70-year-old male diagnosed with Alzheimer?s disease at age 64 is now experiencing severe psychotic symptoms, which are now being considered more psychiatric than physical. Is it common for Alzheimer?s disease to cause a person to exhibit such severe psychosis or is it more likely that his problem is of a psychiatric nature and the Alzheimer?s disease is a misdiagnosis?

The condition was first described by Frederick Lewy in 1941 when he described Lewy bodies, which are abnormal inclusions in the cytoplasm (components of a cell outside the nucleus) of cells found in patients who had Parkinson ' s disease (PD).
