EARLY-COGN^3 - Smart Digital Solutions for EARLY Treatment of COGnitive Disability: a Neuropsychological, Neurophysiological and Neurobiological Perspective in Chronic Neurological Diseases - PNRR-MCNT2-2023-12377069

60 subjects with MCI, SCC, PD will be recruited from IRCCS Istituto Centro San Giovanni di Dio, Fatebenefratelli, Brescia, Fondazione Don Carlo Gnocchi - ONLUS, Milan and IRCCS Centro Neurolesi Bonino Pulejo, Messina. Patients will include both male and female subjects affected by CND: PD (Hoehn \& Yahr\<3), MCI (with CDR scale≤0.5, MMSE ≥24) and SCC (Subjective Cognitive Complaints). All patients will undergo treatment sessions of 45 minutes, 3 days a week for 5 weeks: * 30 subjects will be assigned to the tele@cognitive group that will receive home-based cognitive telerehabilitation activities with an innovative digital solution for remote rehabilitation of cognitive difficulties according to the digital therapy delivery model; * 30 subjects will be assigned to the Active Control Group (ACG) that will receive home-based unstructured cognitive stimulation. The two groups will be matched for sex, age, education and performance in the MoCA test. All study participants will be administered a multidimensional assessment by an experienced neuropsychologist at baseline (T0), at post-treatment assessment (T1, 5 weeks from T0) and at 3-month follow-up (T2). In addition, participation in the research involves blood sampling and application of Transcranial Magnetic Stimulation (TMS) before (T0) and after (T1) treatment.
