Clinical Focus
Traumatic Brain Injury
Neuropsychiatric evaluation and treatment for the psychiatric consequences of brain injury.
What is it?
Traumatic brain injury (TBI) occurs when an external mechanical force causes brain dysfunction. TBI ranges from mild (concussion) to severe, with approximately 2.8 million TBI-related emergency department visits in the United States annually. The psychiatric consequences of TBI are among the most common and debilitating long-term sequelae, yet they are frequently undertreated because most psychiatrists lack training in the neurological underpinnings of post-TBI behavioral change.
At Bay Area Neuropsychiatry, TBI is a core clinical focus. Dr. Lodhi and Dr. Patel both completed fellowships in behavioral neurology and neuropsychiatry at Stanford. Dr. Lodhi also maintains a forensic psychiatry practice evaluating TBI cases in legal proceedings.
Clinical Presentation
Depression develops in 25% to 50% of TBI patients within the first year. Anxiety disorders, including generalized anxiety, panic disorder, and PTSD, are present in 20% to 40% of cases. Irritability, aggression, and emotional dysregulation are among the most distressing behavioral changes.
Cognitive complaints are nearly universal after moderate to severe TBI: difficulty with attention, working memory, processing speed, planning, and multitasking. These deficits interfere with work and daily functioning in ways that are invisible to others.
Personality changes after TBI are particularly challenging because they alter the person's sense of self. Apathy, disinhibition, loss of empathy, and poor social judgment can result from frontal lobe injury. These changes are neurologically mediated, not volitional. Sleep disturbance affects 30% to 70% of TBI patients and exacerbates nearly every other psychiatric symptom.
Our Approach
The critical question in post-TBI psychiatry is determining what is neurological, what is psychiatric, and what is both. Depression after TBI can be a direct neurobiological consequence of injury to mood-regulating circuits, a psychological reaction to disability, or both simultaneously.
Standard psychiatric practice typically treats post-TBI depression the same way it treats any depression. But the injured brain responds differently to psychotropic medications. Patients with TBI are more sensitive to side effects, particularly cognitive and sedative effects. Medications that are well-tolerated in the general population can worsen cognitive function in TBI patients.
ADHD-like symptoms after TBI present a diagnostic challenge. The attentional deficits and executive dysfunction closely resemble developmental ADHD. Distinguishing pre-existing ADHD (which increases TBI risk) from acquired attentional deficits (caused by injury) requires a detailed pre-injury history.
Treatment Approach
Our evaluation begins with a comprehensive review of injury records, neuroimaging, and neuropsychological testing when available. We assess current symptoms across all domains: mood, anxiety, cognition, behavior, sleep, and pain.
Pharmacotherapy follows neuropsychiatric prescribing principles: start low, go slow, and minimize polypharmacy. We avoid medications with significant cognitive or sedative burden. SSRIs remain first-line for post-TBI depression and anxiety. Stimulants or modafinil may be considered for attentional deficits. We coordinate with neurologists, neuropsychologists, and rehabilitation specialists.
Why This Is Different at Our Practice
Dr. Lodhi and Dr. Patel both completed behavioral neurology and neuropsychiatry fellowships at Stanford, where they received specialized training in post-TBI psychiatry. This level of subspecialty training is rare. The injured brain responds differently to psychiatric medications, and standard prescribing practices must be modified.
Dr. Lodhi also maintains a forensic psychiatry practice evaluating TBI cases in legal proceedings, which means his clinical opinions regarding brain injury are regularly tested in adversarial settings. This forensic experience sharpens the clinical rigor he brings to every TBI evaluation.

Frequently Asked Questions
How soon after a TBI can psychiatric symptoms develop?+
Psychiatric symptoms can develop immediately after a TBI or emerge weeks, months, or even years later. Depression and anxiety frequently appear within the first year. There is no safe period after which psychiatric sequelae can be ruled out.
Why do TBI patients need a neuropsychiatrist?+
The injured brain responds differently to psychiatric medications. TBI patients are more sensitive to sedative and cognitive side effects, and medications safe in the general population can impair recovery. Neuropsychiatrists are trained to prescribe within these constraints and to distinguish neurological from psychiatric symptoms.
Can a mild TBI cause lasting psychiatric problems?+
Yes. While most people recover from mild TBI within weeks, a subset experience persistent depression, anxiety, cognitive complaints, and sleep disturbance. If symptoms persist beyond three months, a neuropsychiatric evaluation is appropriate.
Do you work with attorneys on TBI cases?+
Yes. Dr. Lodhi maintains a separate forensic psychiatry practice for TBI litigation. Clinical treatment and forensic work are kept separate to avoid conflicts of interest.
