Lewy Body Dementia: Symptoms & Signs

Lewy body dementia is one of the most common causes of dementia after Alzheimer disease. Lewy bodies are abnormal clumps of protein that form within the brain. There are two types of Lewy body dementia, known as dementia with Lewy bodies and Parkinson disease.

Signs and symptoms of Lewy body dementia are similar to those of other types of dementia, with a few exceptions. Lewy body dementia does not cause the same extent of short-term memory loss as Alzheimer dementia. However, Lewy body dementia often causes hallucinations, which do not occur until late in the disease course of Alzheimer disease. Other associated signs and symptoms of Lewy body dementia include movement-related problems like

• tremor,
• shuffling walk, and
• slowed movement.
