Lewy Body Dementia


Lewy body dementia is an umbrella term for two different types of dementia: dementia with Lewy bodies (DLB) and Parkinson’s disease dementia (PDD).  Lewy body dementia is a progressive, challenging condition, which is thought to be the cause for 10-15% of people with dementia. In the early stages, it is often mistaken for Alzheimer’s disease and can be misdiagnosed. However, it differs from Alzheimer’s in that it can particularly affect the person’s movement (Parkinsonism), and can cause hallucinations, delusions, changes in alertness and sleep disturbances.
