About this trial

The study is designed to characterize the clinical, neuropsychological, polysomnographic, and neuroimaging findings among subjects with Alzheimer's disease, Lewy Body dementia, and Parkinsons' Disease.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Subjects must meet the standard clinical criteria of the syndromes of interest

All subjects must have enough cognitive abilities to complete study procedures, which will be operationally defined as having a Mini Mental State Examination (MMSE) score greater or equal to 10.

Subjects must be on stable cognitive and psychoactive medication regimen for the preceding four weeks of enrollment.

Subjects must have a responsible study partner that either lives with them or is in regular contact with them at least 4 out of 7 days per week.

Disqualifiers

Any other condition (other than the primary diagnosis), which in the opinion of the investigators might contribute to the syndrome of dementia or complicate its assessment.

active medical disorder that could preclude participation in this protocol

Women who are pregnant or are breast feeding

severe renal impairment as defined by glomerular filtration rate (GFR) less than 30 (may have increased radiation exposure with the DaTscan).

Trial population

Subjects must have a clinical diagnosis of either Alzheimer's disease, Lewy Body Dementia, or Parkinson's disease.
