Lewy body dementia (LBD) is a mental disorder associated with the deposition of alpha-synuclein in Lewy bodies in the brain. Lewy body dementia is the second most common progressive cognitive impairment after Alzheimer’s disease. The incidence rate of Lewy body dementia increases with age and is 15-20% worldwide. Recent research has indicated that Lewy body dementia is far more prevalent than previously thought.

It turns to the important role nurses and nursing assistants have in caring for people with Lewy body dementia.
