Dr. Benjamin Elder is a Professor of Neurosurgery, Orthopedics, and Biomedical Engineering at the Mayo clinic. He has an interest in better understanding idiopathic normal pressure hydrocephalus (iNPH). In collaboration with a team of neurologists, neuroradiologists, neuro-ophthalmologists and biomedical engineers, Dr. Elder is investigating improved imaging and functional diagnostic tests for the diagnosis and characterization of iNPH. Additionally, his group is working to develop new tools to assess and optimize the gait apraxia in patients with iNPH, and explore the clinical and functional outcomes of patients treated with CSF diversion procedures. Dr. Jeremy Cutsforth-Gregory is an Associate Professor of Neurology at the Mayo Clinic in Rochester, Minnesota, working in the Division of Neurologic Education, where he completed his medical training and joined the staff in 2016. His clinical practice and research interests span general neurology education, autonomic disorders, and abnormal CSF dynamics. He is a founding member and director of the CSF Dynamics Clinic, collaborating across multiple departments to advance understanding and treatment of low and high CSF pressure disorders.
