The current study seeks to evaluate cognitive behavior therapy for insomnia (CBT-I), a non-medication treatment, in recent TBI patients compared to a sleep education control intervention. Patients will participate in CBT-I treatment (or sleep education treatment) weekly for six weeks, and will have a 3-months follow-up visit in order to examine the efficacy and time course of treatment. In addition, participants will complete several self-report questionnaires in order to examine sleep and neuropsychiatric symptoms throughout treatment.
