What to know about Lewy body dementia

Lewy body dementia (LBD) is a type of dementia that affects cognitive and motor skills.

LBD affects 1.4 million people and their families in the United States. It is the third most common form of dementia after multiple sclerosis and Alzheimer’s disease.

LBD is a progressive disease caused by abnormal deposition of a protein called alpha-synuclein in the brain.

According to a trusted source, the National Institute on Aging (NIA), in a healthy brain, alpha-synuclein plays an especially important role in synapses. With LBD, Lewy bodies form in synapses. This causes nerve dysfunction and death.

Lewy bodies can also affect a person’s mental abilities, mood and behavior by causing changes in brain chemicals.

Both types are caused by the same changes in the brain. Although the initial symptoms are different, people with both types of LBD eventually experience similar symptoms.
