What is Dementia with Lewy bodies?
Dementia with Lewy bodies (DLB) is a type of dementia that shares symptoms with both Alzheimer’s disease and Parkinson’s disease. It may account for 10-15 per cent of all cases of dementia. DLB can be diagnosed wrongly and is often mistaken for Alzheimer’s disease. This section describes the symptoms of DLB and how it is diagnosed, as well as the treatment and support available.
DLB is sometimes known by other names. These include Lewy body dementia, Lewy body variant of Alzheimer’s disease, diffuse Lewy body disease and cortical Lewy body disease. All these terms refer to the same condition.
