Meet the Cognitive and Behavioral Neurology Team

We are a multidisciplinary group with specialists in behavioral neurology, neuropsychiatry, geriatric psychiatry, neuropsychology, and social work. Our team is well-positioned to provide patients with the best possible care.

Behavioral Neurology

Focuses on diagnosis and treatment of patients with neurodegenerative diseases and neurobehavioral syndromes that impair cognition and function (e.g., Alzheimer disease, dementia, disorders of cognition, memory attention, and language). Integrates neurologic, medical, and neuropsychological information to formulate a comprehensive treatment plan.
