What is dementia with Lewy bodies (DLB)?

ANSWER

Lewy bodies are microscopic deposits of a protein that form in some people's brains. They're named after the scientist who discovered them.

If someone you know gets DLB, it's because these deposits have formed in the part of the brain called the cortex.
