A neuropsychological evaluation is a comprehensive assessment that measures cognitive functions such as memory, attention, problem-solving, and language skills. This evaluation is typically conducted by a trained professional, such as a clinical psychologist, and involves a series of standardized tests and interviews to understand an individual's brain function and behavior. These evaluations are often used to diagnose conditions like dementia, ADHD, or traumatic brain injury. The results can help guide treatment plans, educational strategies, and rehabilitation efforts, providing valuable insights into how brain health affects daily life and functioning.
