The purpose of this study is collect clinical information, brain imaging scans, and biological samples from people with dementia with Lewy bodies. The information and samples collected will be analyzed for discovery of new biomarkers (biological signs) of DLB. People with mild cognitive impairment associated with Lewy body dementia are also needed.

This trial is testing an experimental drug, nelotanserin, to determine if it is safe and effective in treating visual hallucinations in people with Lewy body dementia.

A clinical study of an investigational medication, nelotanserin, is now recruiting. Research participants who have dementia with Lewy bodies (DLB) plus REM sleep behavior disorder (physically acting out dreams during sleep) are needed.

The aim of this study is to develop better biomarkers for diagnosis and treatment of Lewy body disorders.
