About Aaron Ritter, MD

Aaron Ritter, MD, Associate Staff, Neuropsychiatry and Behavioral Neurology as well as the Director of Clinical Trials at the Cleveland Clinic Lou Ruvo Center for Brain Health.

Dr. Ritter treats adult Neurological patients and also leads the clinical Research Department by conducting urgently needed trials to advance the prevention, early detection, and treatment for Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, and Huntington’s disease.  With more than 50 drugs and diagnostic trials being conducted at the Center, the Lou Ruvo Center for Brain Health is one of the largest and most active clinical research facilities for memory disorders in the country.

Dr. Ritter initially joined the Cleveland Clinic Lou Ruvo Center for Brain Health in July 2014 as a clinical fellow in Behavioral Neurology and Neuropsychiatry. Dr. Ritter comes to Las Vegas from Tucson following completion of his internship (in pediatrics) and three year residency (in psychiatry) at the University of Arizona.

At the University of Arizona, Dr. Ritter was involved in research projects looking at the neurocircuitry of emotional disorders, the effect of hypothyroidism on mood states, and psychiatric presentations of neurodegenerative disorders. He received two research awards from the University of Arizona for his work on these projects. In addition, Dr. Ritter developed a strong interest in medical education. Following completion of his internship, he received a distinguished teaching award that recognized him as one of the top three “resident educators” out of a pool of more than 600 residents and fellows.

During his two year clinical fellowship at the Lou Ruvo Center for Brain Health, Dr. Ritter received further training in diagnosing and treating neurodegenerative disorders such as Alzheimer’s disease, frontotemporal dementia, dementia with Lewy bodies, and chronic traumatic encephalopathy.
