Behavioral neurologists explore the intersection of brain function and behavior, focusing on how neurological diseases impact cognition, emotion, personality, and language. They diagnose and manage disorders like Alzheimer’s disease, frontotemporal dementia, aphasia, and other cognitive-behavioral syndromes linked to brain dysfunction. Through careful neurological exams and neuropsychological testing, they assess attention, memory, executive function, and emotional regulation. These specialists help differentiate between psychiatric and neurologic causes of behavioral changes. They collaborate extensively with psychiatrists, neuropsychologists, and geriatricians to form comprehensive treatment plans. Behavioral neurologists are actively involved in research on neural circuits underlying behavior and the development of biomarkers for early cognitive decline. Their contributions are vital in advancing therapies that target not just biological pathology but also the lived cognitive experience. As populations age, behavioral neurologists are key to addressing the rising prevalence of dementia and guiding families through its complex care demands.
