Use of Methylphenidate in Traumatic Brain Injury

Abstract

OBJECTIVE To review literature regarding the effectiveness of methylphenidate in the management of the cognitive and behavioral changes observed following traumatic brain injury (TBI). DATA SOURCES A literature search was conducted using the following databases: MEDLINE (1966–June 2004); Cochrane Central Register of Controlled Trials, fourth quarter 2004 (1988–June 2004); and International Pharmaceutical Abstracts (1970–June 2004). Methylphenidate and brain injury were the key search terms used. Limits were set to include clinical trial publications, human subjects, and English language. DATA SYNTHESIS Ten clinical trials evaluating the efficacy and safety of methylphenidate in pediatric and adult patients with TBI are reviewed. Improvements in different aspects of cognition and behavior were evaluated before, during, and after treatment with methylphenidate. The results demonstrated that methylphenidate is likely to improve memory, attention, concentration, and mental processing, but its effects on behavior have not been determined. CONCLUSIONS Larger, double-blind, placebo-controlled studies are needed to determine optimal doses, during which phase of recovery to begin treatment, length of treatment, and long-term effects for patients with mild, moderate, and severe TBI.
