Neuropsychologist is a broader label covering several distinct roles, all concerned with the relationship between the brain and behaviour, but doing quite different work day to day. Most people searching for this title are actually looking for a clinical neuropsychologist, who assesses and treats people whose thinking has been affected by injury or illness, adults in the main.
Different neuropsychologists, different work
Paediatric neuropsychologists apply the same assessment approach to children, where the central questions are usually about development and school rather than return to work or independent living. Cognitive neuropsychologists work mainly in research, using patterns of impairment to understand how the healthy brain organises thought in the first place, and rarely see clients directly. Forensic neuropsychologists prepare expert assessments and reports for courts, often in cases involving brain injury, capacity, or the reliability of a defendant's or witness's account.
What they have in common
Across all of these variations, a neuropsychologist is a psychologist rather than a medical doctor, and in the UK is usually registered with the Health and Care Professions Council with further specialist training on top of core psychology qualifications. If you are looking for assessment or support following a brain injury or neurological diagnosis, it is worth checking which of these strands a particular practitioner works in, since the day-to-day work differs considerably between them.
