Neuropsychology in the Courtroom

Full course description

Defendants in criminal cases increasingly state that they do not have any memory for the offence. This raises the question whether this is always a valid defence. Moreover, defendants and witnesses with traumatic brain injury, those who have taken recreational drugs such as cannabis, and/or who are intoxicated are becoming more common in legal settings. But how accurate are their statements? And how should they be assessed?

Criminal courts are becoming increasingly aware of the unique and important contribution neuropsychological assessment may have to mental health evaluations in forensic practice. As a result, neuropsychologists are being asked to prepare reports in both civil and criminal cases: physical/psychological injury cases, and competency assessment (competency to stand trial and criminal responsibility). The neuropsychological evaluation is typically based on multiple sources of information (case files, medical files, neuropsychological assessment, etc.). The most difficult part of the assessment is often the interpretation of the neuropsychological evaluation within the legally relevant criteria. Because every expert witness in the courtroom will sometimes be confronted with neuropsychological issues, it is important to have basic knowledge on brain structure and function, brain-behavior relationships, neuropsychological assessment and legal issues related to neuropsychology. Moreover, the use of high-tech brain imaging techniques in defendants, to explain or underscore specific theories on brain-behaviour relationships, is becoming increasingly common nowadays. But what is the value of such brain images in individual defendants? Given the increased demand for experts in the courtroom, it is desirable to have expertise in this particular field.
