Methylphenidate (Ritalin) and Memory/Attention in Traumatic Brain Injury (TBI)

Summary

Traumatic brain injury (TBI) is a significant public health problem, with 1.5-2.0 million Americans injured each year. Cognitive deficits, particularly in the domains of memory and attention are frequently the source of lingering disability after TBI and a source of enormous distress to the injured individuals and their family/caregivers. To date, interventions to ameliorate chronic cognitive deficits have been directed at either pharmacological interventions or cognitive rehabilitation. We propose to (1) To compare the efficacy of three interventions: memory and attention training (MAAT), methylphenidate, and memory/attention training in combination with methylphenidate and (2) use functional MRI (fMRI) to characterize changes in activation of the neural circuitry of memory and attention due to MAAT alone, methylphenidate alone, and MAAT in combination with methylphenidate. This is a two by two design with medication (methylphenidate/placebo) and cognitive therapy (Memory and Attention Training (MAAT) or an Attention control intervention) as possible interventions. Using a randomized, placebo-controlled, double-blind design, 200 individuals with persistent cognitive deficits 6-12 months after MTBI will be randomized to receive a six week trial of either (1) MAAT and placebo, (2) MAAT and methylphenidate (0.3 mg/kg BID), (3) attention control intervention and methylphenidate (0.3 mg/kg BID), or (4) attention control intervention and placebo. Symptom distress, attention and memory performance, and activation patterns of the neural circuitry of attention and memory while undergoing fMRI will be characterized at baseline, and after the four treatment conditions. This study will provide important information on three interventions for the most disabling sequelae of an enormous public health problem. Further, it will help to clarify underlying neural mechanisms and suggest additional treatment possibilities.
