Males and females (n=30), between the ages of 18 and 55 years in the chronic stage after TBI who experience deficits in neuropsychological function from TBIs incurred 6 months after the injury, will be recruited from military treatment facilities or civilian clinics when presenting for clinical management of TBI or post-concussive symptoms. 1. Study participants will be evaluated using brain MRI, psychometric measures adapted from the TBI Common Data Elements, attention tests and information about details of the injury and experience of post-concussive symptoms will be recorded. Transcranial magnetic stimulation (TMS) with placebo and with methylphenidate (60 mg by mouth) challenge will be performed to predict a stimulant response. 2. Subjects will be studied with [11C]-raclopride PET in two imaging sessions. One session will be after administration of placebo and the other after methylphenidate, 60 mg by mouth. Both placebo and methylphenidate will be given 60 minutes prior to injection of [11C]-raclopride to allow for peak uptake of methylphenidate in the brain. The binding potential of [11C]-raclopride relative to a non-displaceable reference region (cerebellum), BPND, will be used as a measure of D2/D3 receptor availability. The difference in BPND between methylphenidate and placebo (ΔBPND) is used to measure of tonic DA release. 3. Subjects will then be treated with oral methylphenidate, using a forced titration up to a dose of 30 mg given twice daily for 4 weeks. At that point, the neuropsychologic tests are repeated. Outcome measures: The primary outcome is change in information processing speed during neuropsychologic testing.
