A Clinical Neuropsychologist is a specialized psychologist who focuses on understanding how brain function affects behavior and cognitive abilities. They assess and diagnose conditions related to brain injuries, neurological disorders, and cognitive impairments through various tests and evaluations. These professionals often work with patients who have experienced trauma, strokes, or diseases like Alzheimer's or Parkinson's. By interpreting test results, they help develop treatment plans and rehabilitation strategies to improve patients' quality of life and cognitive functioning.
