The study is designed to determine the diagnostic efficacy of the visual assessment of SPECT scans in differentiating between probable dementia with Lewy Bodies (DLB) and non-DLB dementia subjects determined by the clinical diagnosis of an independent expert consensus panel used as the standard of truth.

Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • Sensitivity and specificity of DaTSCAN SPECT scans in differentiating between probable dementia with Lewy Bodies (DLB) and non-DLB dementia subjects.

Secondary Outcome Measures:
  • Accuracy, positive predictive value and negative predictive value of DaTSCAN SPECT
  • Semi-quantitative analysis of the striatal uptake ratios of DaTSCAN SPECT images.
  • Impact of DaTSCAN SPECT analysis on the confidence of diagnosis.
  • Findings in relation to probable, possible and no-DLB.
  • Efficacy analysis at 12-month follow-up period.
  • Safety profile

Estimated Enrollment: 326

Ages Eligible for Study:   55 Years to 90 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects must be adults between 55 to 90 years of age with an established diagnosis for dementia in accordance with DSM-IV criteria and have to fulfil at least one of the following: The ICC criteria for probable and possible DLB, the National Institute of Neurological and Communicative Disorders and Stroke and Alzheimer Disease and Related Disorders Association (NINCDS-ADRDA) for Alzheimer’s Disease (AD), or the National Institute of Neurological and Communicative Disorders and Association Internationale Pour la Recherche et l’Enseignement en Neurosciences (NINCS-AIREN) for Vascular Dementia (VaD).

Exclusion Criteria:

  • Subjects are not eligible if they have a Mini Mental State Examination (MMSE) score of <10 and use medication known or suspected to interact with the striatal uptake DaTSCAN to the dopamine transporter.
  • Furthermore subjects are not eligible if they were diagnosed with idiopathic Parkinson’s Disease (PD), with persistent severe depression, normal pressure hydrocephalus, multiple system atrophy, cortico-basal degeneration or Huntington’s Chorea Disease.
