Feasibility and acceptability of a remote computerized cognitive training employing telehealth in older adults with subjective cognitive complaints.

Introduction
Computerized cognitive training (CCT) represents promising solutions for remote training of cognitive abilities in older people with cognitive decline. In the present article, we tested the feasibility and acceptability of a CCT performed at home via a telehealth platform, with participants connected remotely to a clinician, in comparison to an in-person CCT.Methods
Thirty participants took part in the study. Twelve participants opted for classical in-person training and met a neuropsychologist twice a week for 12 weeks, for a total of 24 30-minute sessions. Eighteen participants opted for the remote home-based training and met with the clinician virtually via a telehealth system at the same frequency and duration. The intervention consisted of a serious-game platform training memory, spatial abilities, and executive functions. All participants underwent a neuropsychological and clinical assessment before and after the training.Results
Results showed a high adherence to training and a strong acceptability in both the remote and the in-person groups. A significant improvement in mental flexibility and planning abilities was observed in both groups (as measured by the Zoo planning test), but no other neuropsychological tests showed improvement.Discussion
This non-randomized study suggests the feasibility and acceptability of the telehealth CCT intervention. When participants are able to select their preferred intervention modality, training adherence and efficacy are comparable between remote and in-person delivery. Future studies should be performed to verify which are the most effective intervention parameters, such as training frequency and duration.
