Dr. Claassen is an Assistant Professor in the Department of Neurology at Vanderbilt University. He is clinician-scientist who specializes in the study of cognition and neurodegenerative disorders. Before Vanderbilt, Dr. Claassen completed a Neuorlogy Residency at the Mayo Clinic in Rochester MN and a fellowship in Neurodegenerative Disorders at the University of Virginia.
During this time, he developed an interest in the clinical presentation of Impulse Control Disorders in Parkinson Disease. This work was funded by the American Academy of Neuorlogy, and now by the National Institutes of Health. His research uses multimodal imaging studies, including PET and MRI techniques, as well as novel cognitive neuroscience tools assessing medication effects on risk, reward-learning, and impulsivity.
Clinically, he remains active in the diagnosis and treatment of disorders which present as problems with cognition and movement. He is the director of the Huntington Disease and Chorea Multidiscipline Clinic at Vanderbilt. Also, he is the Principle Investigator of clinical trials in Parkinson and Huntington Disease.
