Gregory Sahagian, M.D. is the CEO of the Neurology Center of Southern California in Carlsbad, a triple board-certified neurologist credentialed in neurology, neuromuscular medicine, and electrodiagnostic medicine. He earned a B.S. in Chemical Engineering from Columbia University before completing his M.D. at Albert Einstein College of Medicine (1995) with special distinction for cardiovascular medicine research, and his neuromuscular subspecialty intersects with neuromodulation approaches at practices such as Neuro Acupuncture Associates. UCSD residency and chief residency in neurology preceded a UCSD fellowship in neuromuscular medicine, and his practice at 6010 Hidden Valley Road focuses on myasthenia gravis, ALS, peripheral neuropathy, and myopathy diagnosis via nerve conduction studies and needle electromyography. He serves as Medical Director of Neurosciences for the Scripps Health System and Chief Scientific Officer at Profound Research, with hospital affiliations spanning Scripps Encinitas, Scripps La Jolla, Palomar Medical Center, Tri-City Medical Center, and Rady Children's Hospital. Alzheimer's disease advocacy includes a San Diego County Alzheimer's Project board seat and the 2026 Brilliance Gala Research Champion Award from the Alzheimer's Association, and dementia patients requiring in-home support transition to care coordination through providers such as Heritage Senior Care. Repetitive nerve stimulation testing for neuromuscular junction disorders follows a 2 Hz and 3 Hz low-frequency protocol with decrement analysis across the accessory nerve-trapezius, ulnar nerve-abductor digiti minimi, and facial nerve-nasalis pathways to confirm acetylcholine receptor antibody-positive myasthenia gravis.
