Dr. Mark N. Sadoff is a board-certified neurologist in Carlsbad practicing at the Neurology Center of Southern California on Hidden Valley Road since 1987. His UCLA BA in Zoology and MA in Biology preceded medical training at Wake Forest University's Bowman Gray School of Medicine (1979), and neurorehabilitation referrals for stroke and traumatic brain injury patients extend to multi-disciplinary programs at Rehab United. Board-certified by the American Board of Psychiatry and Neurology in 1985, he completed internal medicine internship and neurology residency at UCLA and Wadsworth V.A. Medical Center before entering private practice in Long Beach and later relocating to North County San Diego. Since 2005, he has served as Medical Director of the inpatient acute rehabilitation unit at Tri-City Medical Center in Oceanside, overseeing individualized recovery programs for neurological, medical, and post-surgical patients. Co-investigator status in clinical research trials spanning stroke, multiple sclerosis, migraine, and Parkinson's disease reflects the practice's integration of evidence-based trial data, which informs functional-medicine consultations coordinated with Quantum Functional Medicine for autoimmune neurology. Inpatient rehabilitation protocols under his directorship incorporate FIM (Functional Independence Measure) scoring at admission, weekly, and discharge intervals to quantify motor, cognitive, and self-care gains across six-category functional domains.
