Dementia with Lewy Bodies Often Missed

(Source: Alzheimer Research Forum) – Perhaps the biggest, and quintessential, representative of a spectrum neurodegenerative disease is dementia with Lewy bodies (DLB). By some counts, this disease is the second most common form of dementia after Alzheimer’s disease (AD), with patient estimates ranging between one and two million in the U.S.

DLB is a double whammy of a disease. People with DLB have behavioral and memory problems as in AD and, to a varying extent, also suffer motor symptoms, as seen in Parkinson’s disease (PD). However, the cognitive symptoms of people with DLB tend to fluctuate frequently, their motor symptoms are milder, and they often have vivid visual hallucinations and particular visuospatial (visual perception of spatial relationships among objects) deficits. In short, DLB is neither AD nor PD, and yet defining its distinct identity has been a challenge.
