Overview

Dementia with Lewy bodies (DLB) is a type of progressive dementia that is the second most common form of neurodegenerative dementia after Alzheimer's disease. It is caused by the buildup of alpha-synuclein protein (Lewy bodies) in brain cells, affecting movement, thinking, and behavior.

Symptoms

Symptoms include fluctuating attention and alertness, recurrent visual hallucinations, Parkinsonian symptoms (rigidity, slow movement, tremors), REM sleep behavior disorder, and cognitive impairment affecting memory and problem-solving.

Causes

The exact cause is unknown, but it involves the accumulation of Lewy bodies in the brain. Genetic and environmental factors may play a role. It shares features with both Alzheimer's and Parkinson's disease.

Treatment

There is no cure. Treatment focuses on managing symptoms and may include cholinesterase inhibitors for cognitive symptoms, medications for Parkinsonian symptoms, and strategies to manage hallucinations. Physical therapy and occupational therapy are also beneficial.
