Genetic study of Lewy body dementia supports ties to Alzheimer’s and Parkinson’s diseases

In a study led by National Institutes of Health (NIH) researchers, scientists found that five genes may play a critical role in determining whether a person will suffer from Lewy body dementia, a devastating disorder that riddles the brain with clumps of abnormal protein deposits called Lewy bodies.
