A 29-year-old man is referred to the PMHNP eight months after sustaining a moderate traumatic brain injury (TBI) in a motor vehicle accident. He sustained a frontal lobe contusion with loss of consciousness lasting approximately 30 minutes. He reports new-onset irritability, impulsivity, emotional lability, difficulty with executive planning, and social disinhibition that his wife describes as a 'complete personality change.' He also endorses depressed mood, anhedonia, and difficulty concentrating. He has no pre-injury psychiatric history. Neuropsychological testing reveals deficits in executive function, working memory, and processing speed. The PMHNP evaluates this neuropsychiatric presentation. Which of the following most accurately reflects the assessment considerations for psychiatric symptoms following moderate TBI?
