More Information

My research life started in the field of cognitive impairments, dementia, neurodegeneration, and Alzheimer''''s disease. As my PhD. thesis, under the supervision of Dr. Seyed-Mahdi Khaligh-Razavi, I studied and searched for any difference in the brain of the healthy subjects, those with mild cognitive impairment and mild Alzheimer''''s disease with applying task-based functional MRI. fMRI was acquired while subjects were doing an ultra-rapid visual animacy categorization task called the Integrative Cognitive Assessment (ICA) test (Khaligh-Razavi, 2019, Scientific Reports). Before entering the Ph.D. program, I got my medical degree at the Tehran University of Medical Sciences (TUMS). Following graduation, I spent two years of medical practice in the emergency department of Qom pediatric central hospital; immediately after that participated in the Ph.D. exam in neuroscience and joined the Institute for Research in Fundamental Sciences, School of Cognitive Sciences. From the beginning of my Ph.D. thesis, my clinical and academic lives have been merged together to work more specifically in clinical cognitive neuroscience. I am now active in the area of research by using neuroimaging in the early stages of Alzheimer''''s disease, and prevention, early detection, cognitive, neuropsychological, and behavioral assessment, and management of geriatrics.
