Dr. Claassen’s research focus is to understand brain-behavior relationships in the context of the diagnosis and treatment of neurodegenerative diseases. His research studies assess therapeutic outcomes in neurodegenerative disorders, using innovative cognitive neuroscience and neuroimaging tools. In Parkinson disease, he examines how dopaminergic medications can alter behavior, and his current studies address cognitive changes that account for impulsive compulsive behaviors. His research uses multimodal imaging studies, including assessments of blood flow (arterial spin labeling), resting state BOLD connectivity, MR spectroscopy, and Positron Emission Tomography, as well as novel cognitive neuroscience tools assessing medication effects on risk, reward-learning, and impulsivity.
