He currently shares his time between research and clinical work (at Eginition Hospital). His clinical work includes seeing elderly patients with dementias and cognitive dysfunction, supervising and teaching of Medical students and Neurology residents.

His research interests have started from the topic of cognitive reserve (i.e. how higher IQ, education, more demanding occupational attainments, or more engagement in cognitive-social-physical leisure - lifestyle activities can help elderly cope better with the damage caused to their brains by Alzheimer’s disease and aging and therefore reduce their risk for dementia and slow down their rates of cognitive and functional decline). More recently, he has developed a special interest in the contribution of diet (in particular composite dietary patterns such as a Mediterranean-type diet and others) and physical activity in dementias and healthy aging.

Dr Scarmeas is the Principal Investigator in studies funded by either the Alzheimer's Association (IIRG) or the NIH-NIA (RO1) and a Co-Investigator in multiple others. His research work has resulted in more than 120 original publications in highly esteemed journals (>5200 citations, H-index = 41) and multiple presentations in internationally acclaimed scientific conferences - meetings. He reviews for more than 120 international scientific journals and international funding agencies including the Alzheimer’s Association, the US National Institute of Health, the European Union Marie Curie programs etc.
