LEWY BODY DEMENTIA
Lewy body dementia is a form of dementia that occurs because of abnormal deposits of a protein called alpha-synuclein inside the brain's nerve cells. These deposits are called "Lewy bodies," after the scientist who first described them. The deposits interrupt the brain’s messages. Lewy body dementia usually affects the areas of the brain that involve thinking and movement. Why or how Lewy bodies form is unknown.
Lewy body dementia can occur by itself, or together with Alzheimer's disease or Parkinson's. It accounts for 5-15% of all dementias.
