ABSTRACT.Dementia is a neurological disorder that affects memory, thinking, orientation, and other important functions of the brain; telemedicine is a part of the healthcare delivery system involving diagnosis and consultation over telecommunications devices such as mobile phones and computers. In this review, we assessed the impact, accessibility, and possible improvements in telemedicine in dementia treatment. Regarding the use of telemedicine in the treatment, we evaluated its impact on the management of the disease (i.e., diagnosis and follow-up). We also evaluated studies on the current improvements and accessibility of telemedicine in dementia treatment. The review findings showed that it is effective in diagnosing patients, monitoring their progress during treatment, and providing caregiver support. However, studies have revealed a lack of accessibility and improvement in telemedicine among the elderly, particularly in West African countries. Finally, lasting solutions were provided to address the problems in the review permanently.
