Brief Summary:

In this pilot study the investigators shall prospectively in a blinded fashion evaluate with Aβ PET in patients committed to shunt surgery and then investigate the relationship of these biomarkers with outcome on gait, cognition and urinary control improvement in the short term (3 months) and long term (1 year). The imaging agent will be provided by AVID.

Furthermore the study will standardize imaging studies using florbetapir F 18 PET to provide information on amyloid burden.

Criteria

Inclusion Criteria:

  2. History of alcohol or substance abuse or dependence within the past 2 years (DSM IV criteria).
  3. Participation in clinical studies involving neuropsychological measures being collected more than one time per year.
  4. Exclusion for amyloid imaging with 18F -AV-45: Current or recent participation in any procedures involving radioactive agents such that the total radiation dose exposure to the participant in any given year would exceed the limits of annual and total dose commitment set forth in the US Code of Federal Regulations (CFR) Title 21 Section 361.1.
  5. Clinically significant hepatic, renal, pulmonary, metabolic, or endocrine disturbances as indicated by history, which in the opinion of the investigator might pose a potential safety risk to the participant?
