Ages Eligible for Study:   50 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria DLB:

  • Male or female > 50 years of age
  • Meet the diagnostic criteria for probable DLB as established by the DLB Consortium (McKeith et al., 2005)

Inclusion Criteria AD:

  • Male or female > 50 years of age
  • Meet the NINCDS criteria for probable AD and have a Mini Mental State Examination (MMSE) score at screening between 10 and 24 inclusive

Inclusion Criteria PD:

  • Male or female > 50 years of age
  • Have probable PD according to the following criteria (Gelb et al., 1999):

    • Presence of 2 of the following 3 features: rest tremor, rigidity, bradykinesia;
    • Documented history of a sustained (>6 months) improvement to Levodopa (L-DOPA) or a dopamine agonist
    • Absence of atypical clinical features or other possible signs or symptoms suggesting another cause of parkinsonism such as a history of frequent falls as a prominent early feature, localized brain lesion(s) or neuroleptic use
    • Asymmetric onset
  • A diagnosis of PD made within the 4 years prior to enrollment

Normal subjects:

  • Are males or females > 50 years of age
  • Have a MMSE score > 29, and are cognitively normal on the psychometric test battery at screening
  • Have no signs or symptoms of clinically meaningful parkinsonism

Exclusion Criteria:

  • Have a history or current diagnosis of other neurologic disease
  • Have evidence of clinically significant cerebrovascular disease
  • Have evidence from MRI or other biomarker studies that suggests the presence of a CNS pathology other than that associated with the study diseases
