Neurology & Neurosurgery Clinical Trials

Providing state-of-the-art care for people with brain and nervous system disorders is our most important commitment. As a neurology or neurosurgery patient at Cedars-Sinai, you have access to clinical trials and research aimed at improving testing methods, treatments, quality of life and recovery. These studies are open to people with a broad range of neurological conditions.
