title: The effect of telemedicine on cognitive decline in patients with dementia.
abstract: Introduction Telemedicine has the advantage of providing medical resources in rural areas, but few studies have been conducted to investigate its efficacy in dementia care, compared to face-to-face care. This study evaluated the effectiveness of telemedicine in relation to cognitive changes in patients with dementia. Methods We evaluated cognitive changes over time, according to care modality, in 188 patients with dementia who were registered at our university-based dementia clinic. We followed 98 patients using telemedicine services and 90 patients who attended the dementia clinic in person. Patients in the telemedicine group also visited a public health center located in a rural area about 50 km from the dementia clinic. Results Changes in the mean annualized Mini-Mental State Examination (MMSE) score were not significantly different between the telemedicine group and the face-to-face dementia clinic group ( p = 0.291), with changes of 0.60 and 1.03 points, respectively. However, cognitive decline was significantly lower in the telemedicine group for the less severe initial cognitive performance subgroup than more severe cognitive performance subgroup ( p = 0.049), with changes of 0.62 and 1.59 points, respectively. Higher initial Clinical Dementia Rating (CDR) scores, MMSE scores, and age were found to be independent predictive factors of subsequent cognitive changes, as indicated by mean annualized MMSE scores. Discussion These findings suggest that telemedicine may be a useful alternative to face-to-face clinical visits for management of dementia in patients who are located in rural areas.
