NCT03273062

Brief Summary

This is a follow-up study for an ongoing open label trial conducted by the Sheppard Pratt-Lieber Research Institute utilizing the catechol-O-methyl-transferase (COMT) inhibitor Tolcapone to evaluate its effects on cognition and neuropsychiatric symptoms in patients with brain injuries (BI). In this study, investigators will conduct a double-blind, placebo-controlled clinical trial utilizing a crossover design to study the effects of two weeks of Tolcapone 200mg administered three times a day (total of 600mg/day) on cognitive performance. Physical, emotional, cognitive and social functioning will also be evaluated through participant and proxy report. The investigators are planning to randomize a total of 12 patients with a history of acquired brain injury (BI).

Outcome Measures

Primary Outcomes (1)

  • NIH Toolbox Fluid Cognitive Battery

    This battery is a measure of cognitive performance derived from a battery of five cognitive assessments.

    Administered on the 14th day of Tolcapone or Placebo treatment (i.e. during each Outcome Measures Visit).

Secondary Outcomes (2)

  • TBI Quality-of-Life Measurement System

    Administered prior to the start of Tolcapone oe Placebo treatment (i.e. during each Pre-Study Visit) and on the 14th day of Tolcapone or Placebo treatment (i.e. during each Outcome Measures Visit).

  • Frontal Systems Behavior Scale

    Administered prior to the start of Tolcapone oe Placebo treatment (i.e. during each Pre-Study Visit) and on the 14th day of Tolcapone or Placebo treatment (i.e. during each Outcome Measures Visit).
