Lewy bodies are clumps of protein that can form in the brain. When they build up, they can cause problems with the way your brain works, including your memory, movement, thinking skills, mood, and behavior. These problems can keep you from doing everyday tasks or taking care of yourself, a condition called dementia.
Lewy body dementia (LBD) is one of the most common types of dementia, after Alzheimer’s disease. It usually happens to people who are 50 or over. There are two types:
-Dementia with Lewy bodies often starts when you have a hard time moving your body. Within a year, you start to have thinking and memory problems that are similar to Alzheimer’s disease, along with changes in behavior. You also might see things that aren’t there, called hallucinations.
-Parkinson’s disease dementia first causes movement problems. The trouble with memory happens much later in the disease.
