Study Information

In collaboration with approximately 10 centers that specialize in Lewy body dementia (LBD) and dementia, we will recruit a total of 80 individuals for the study. 40 subjects with suspected MCI-DLB and 40 with suspected MCI-AD will be recruited. All subjects will be enrolled into a 12 month longitudinal study where skin biopsies will be performed at 3 sites on each patients at 12 month intervals (baseline and 1 year). Detailed quantified examination, cognitive evaluation, history, and questionnaires will be performed at each visit and will be reviewed by a central panel of disease experts to confirm the diagnosis.

Subjects enrolled in the study will have baseline evaluations and follow up visits at 12 months to define any changes to clinical diagnosis. Skin biopsies will be repeated at the 12 month follow up visit to determine the rate of P-SYN accumulation over time and rates of nerve fiber degeneration within punch skin biopsies.

 

Inclusion Criteria:

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

Exclusion Criteria:

  2. Clinically active coronary artery or cerebrovascular disease
  3. Current smoker or alcoholism
  4. History of allergic reaction to local anesthesia (for biopsy collection)
  5. Use of anticoagulants (aspirin or Plavix alone is allowed)
