Definition:
Lewy Body Dementia (LBD) is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain. These changes can lead to problems with thinking, movement, behavior, and mood.
Dementia with Lewy bodies may have a pattern of decline similar to Alzheimer's Disease. Alertness and severity of cognitive symptoms may fluctuate daily. Visual hallucinations, muscle rigidity, and tremors are common. LBD is one of the most common causes of dementia.
