A Diagnostic Test for Dementia With Lewy Bodies

This study is testing a diagnostic tool called the Syn-One Test, which looks for a protein called alpha-synuclein in a skin biopsy. The goal is to better distinguish between two conditions that are often confused: early Alzheimer's disease and Lewy body dementia. This is a diagnostic accuracy study, not a treatment trial, so no experimental drugs are involved.

You may qualify if

  • Men and women 50 to 85 years of age
  • Clinical diagnosis of mild cognitive impairment, and a presumed etiology of DLB or AD at enrollment

You're excluded if

  • Clinical evidence of severe peripheral vascular disease (Fazekas score of ≥ 3, or a large vessel stroke of ≥ 2 cm, history of ulceration, poor wound healing, vascular claudication)
  • Clinically active coronary artery or cerebrovascular disease
  • Current smoker or alcoholism
  • History of allergic reaction to local anesthesia (for biopsy collection)
  • Use of anticoagulants (aspirin or Plavix alone is allowed)
  • Significantly impaired wound healing or history of scarring or keloid formation
