Causes
By Mayo Clinic staffThe cause of Lewy body dementia isn't known, but the disorder may be related to Alzheimer's or Parkinson's disease.
- Lewy bodies contain a protein associated with Parkinson's disease.
- Lewy bodies often are found in the brains of people who have Parkinson's and other rare dementias.
- People who have Lewy bodies in their brains also have the plaques and tangles associated with Alzheimer's disease.
Some scientists have suggested there's a Lewy body variant of Alzheimer's disease. Conversely, Lewy body dementia and Alzheimer's simply may coexist in some people.
