A neuropsychologist is a professional who studies the relationship between the brain and behavior. They assess and treat individuals with brain injuries, neurological disorders, or cognitive impairments. By using various tests and evaluations, neuropsychologists can identify specific areas of brain function that may be affected, helping to guide treatment and rehabilitation. In their work, neuropsychologists often collaborate with other healthcare providers, such as neurologists and psychiatrists, to develop comprehensive care plans. They may also conduct research to better understand how different brain conditions impact cognitive abilities and emotional well-being, contributing to advancements in the field of neuropsychology.
