Dementia with Lewy bodies

Dementia with Lewy bodies is a less common type of dementia. It is closely related to both Alzheimer’s disease and Parkinson’s disease. Lewy bodies are tiny clumps of protein that develop inside nerve cells.

How quickly dementia with Lewy bodies’ gets worse varies from person to person. Home-based help will usually be needed, and some patients will eventually need care in a nursing home. The average survival time after diagnosis is similar to that of Alzheimer’s disease – around 6 to 12 years. But this is highly variable and some people live much longer than this.

Dementia with Lewy Bodies (DLB) 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 means roughly 100,000 people in the UK are likely to have this form of dementia.
