Background: Executive dysfunction is well established in patients with traumatic brain injury, and in schizophrenia. However, assessments of executive function in psychosis following traumatic brain injury (PFTBI) are limited, inconsistent, and often do not reflect the patterns of deficits demonstrated in traumatic brain injury (TBI) and schizophrenia. Methods: A battery assessing executive function was administered to dually diagnosed PFTBI patients that measured mental inhibition and switching, processing speed, and attention. The battery comprised of the Stroop Task, the Trail Making Test, and the Attention subtest of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Performance was compared with three other cohorts: patients with traumatic brain injury, schizophrenia, and healthy controls. Results: Significant executive dysfunction was shown by patients with PFTBI on all measures. PFTBI patients further demonstrated the poorest performance relative to all three comparison cohorts. Conclusions: These data present novel evidence of substantially impaired executive function across four task types in dually diagnosed PFTBI patients, both relative to health, and the impairments of their brain-injured, and psychotic, counterparts. The data suggest that TBI and presence of psychosis have an additive influence on executive function deficits.
