A forensic neuropsychological evaluation is a specialized form of psychological assessment that aims to identify and understand the cognitive, emotional, and behavioral effects of brain injury, defect, or disease within a legal context. The evaluation typically involves the administration and interpretation of a comprehensive battery of tests, including measures of intellectual functioning, attention, memory, language, perception, and executive functioning. The evaluation also includes interviews with the individual (plaintiff, defendant, or disability claimant) as well as interviews with relevant collateral sources (e.g., spouse/partner, parent, adult child, co-worker, etc.)
 

The primary goal of a forensic neuropsychological evaluation is to determine the presence or absence of cognitive, emotional and/or behavioral impairment. If impairment is observed, the forensic neuropsychological evaluation will help determine whether that impairment is the product of a pre-existing condition or the result of injury, defect, or disease relevant in a particular case. A forensic neuropsychological evaluation will also include an assessment of symptom and performance validity to assess the impact of feigning or malingering. 
 

The process of a forensic neuropsychological evaluation typically involves an in-depth review of records (medical, mental health, educational, legal, etc.). The evaluator should also take into account cultural and demographic factors, sexual orientation and gender identity, as well as any prior medical or psychological history
 

The results of a forensic neuropsychological evaluation are typically presented in a comprehensive report that includes a detailed description of the individual's cognitive strengths and weaknesses. The report will also include opinions concerning the psycho-legal questions relevant in a particular matter. These psycho-legal matters may involve a variety of criminal and civil capacities; criminal responsibility; mitigation at sentencing; or issues concerning negligence or responsibility for injury in civil cases.
