A neuropsychological evaluation is a comprehensive assessment that measures cognitive functions such as memory, attention, language, and problem-solving skills. It typically involves a series of standardized tests and questionnaires administered by a trained professional, often a clinical psychologist or neuropsychologist. This evaluation helps identify any cognitive impairments or changes in brain function. The results of a neuropsychological evaluation can assist in diagnosing conditions like Alzheimer's disease, traumatic brain injury, or attention-deficit/hyperactivity disorder (ADHD). Additionally, it can guide treatment planning and rehabilitation strategies, providing valuable insights into an individual's cognitive strengths and weaknesses.
