Dr. Elissaios Karageorgiou

Dr. Elissaios Karageorgiou was born in Glasgow and raised in Athens, where he graduated from Athens College and completed both his MD and PhD at the National and Kapodistrian University of Athens. He has trained and worked in leading academic medical centers across the U.S., including the University of Minnesota, UCSF, and Stanford.
He began his research career as a post-doctoral associate at the Brain Sciences Center at the University of Minnesota, studying encephalographic brain patterns in health and in disorders such as Alzheimer’s disease, multiple sclerosis, and schizophrenia under the mentorship of Dr. Apostolos P. Georgopoulos. He later completed his Neurology residency at the University of Minnesota, where he also served as Associate Chief Resident for Research and Education.
Dr. Karageorgiou then joined the Memory and Aging Center at the University of California San Francisco, completing a Behavioral Neurology fellowship and participating in the Atlantic Fellows program for Equity in Brain Health. He went on to complete a second clinical fellowship in Sleep Medicine at Stanford Sleep Medicine Center, making him uniquely trained to diagnose and treat conditions at the intersection of sleep and cognition.
Returning to Greece, he established the Sleep & Memory Center at the Neurological Institute of Athens—the first center globally to organically combine Behavioral Neurology and Sleep Medicine. His work integrates clinical practice, research, and education through a truly interdisciplinary team including experts in neurology, psychology, and social work.
