The main objective of this project is two-fold 1. to develop a Dual-Task training exploiting the potentiality of the 360° technology in terms of interactivity and ecological validity 2. to investigate its efficacy in improving the cognitive functioning in a randomized clinical trial for 2 different populations: subjects with subjective memory complaints and mild cognitive impairment. Specifically, participants will follow an integrated training including 2 phases: 1)in-hospital rehabilitation, where subjects will be provided sessions of the training in immersive modality; 2)at-home rehabilitation, where older adults will be asked to perform at home the non-immersive version of the training using a tablet. Expected outcome is an improvement in cognitive functioning (assessed with a complete neuropsychological battery) after the training, thus advancing literature about non-pharmacological interventions in the preclinical stages of dementia along with innovative technical instruments.
