Biography

About Aaron Ritter, MD

Aaron Ritter, MD, Associate Staff, Neuropsychiatry and Behavioral Neurology

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.

    Industry Relationships

    Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

    To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

    As of 9/8/2020, Dr. Ritter has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

    Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities. Click here to view a listing of instances where Cleveland Clinic has identified a Public Health Service (PHS)-Reportable Financial Conflict of Interest and has put measures in place to ensure that, to the extent possible, the design, conduct and reporting of the research is free from bias.
