The prevalence and global health burden of dementia including Alzheimer's disease (AD) is rising, while patients living in remote and underserved areas face significant challenges in reaching specialized care. Telemedicine offers a valuable solution in bridging this widening gap, by providing equal and timely access to tertiary-specialized centers. Accumulating evidence highlights that most parts of the remote neuropsychological and neurological evaluation are feasible, with patients, healthcare professionals and caregivers being generally satisfied with this means of care. Herein, we provide an updated overview of the available evidence on the use of telemedicine for patients with cognitive disorders, focusing on the different applications and settings, the remote, video-based neurological and neuropsychological assessment, current recommendations, non-pharmacological interventions, as well as legal and ethical considerations. Based on the literature review and our three-year experience in the “Specialized Outpatient Clinic of Memory, Dementia and Parkinson's disease through the National Telemedicine Network” in the Aiginition University Hospital of Athens, we propose a brief guide for assessing patients with cognitive impairment via telemedicine and suggest future research directions for the more effective and appropriate use of telemedicine in dementia assessment and care.
