Cognitive and Physical Home-rehabilitation by Information and Communications Technology. Games for Older Adults Active Life (GOAL)

30 patients will be allocated in the treatment arm (Telerehabilitation program, GOAL group) by randomization. Randomization will be applied with a ratio of 1:1.

The Telerehabilitation program is conceived as a combined protocol to train both cognitive and physical domains. Participants will be requested to perform the cognitive training three times weekly and physical training two times weekly, on alternate days. The subject will access the Telerehabilitation contents by using a web application configured on a touchscreen notebook, that will be provided to each participant by the research institute.

Physical exercises are going to be chosen according to adaptive physical activity model, and each session will be made up of eleven exercises, divided in three categories: warm-up, strengthening and stretching/relaxation. The participants will perform the exercises according to instructions received in a sequence of videos. Every session will last 30 minutes.

Cognitive training will be based on BrainHQ exercises (BrainHQ, Posit Science,USA) which are characterized by adaptive control of the difficulty levels. The chosen exercises aim to train different cognitive domains including: attention, executive function, memory, processing speed, reasoning, and visuospatial memory. Each session will last 20 minutes, and will include four different types of exercise.

While enrolled in the 8 weeks program, participants will also be requested to wear an actigraph. The actigraph will be placed on the non-dominant arm and will be used to monitor daily activity and sleep quality.

At the end of the tele-rehabilitation program, participants will undergo a final assessment.

Inclusion criteria

• Age between 65 and 80 years old
• Agreement to participate, with signature of the informed-consent form
• Availability of a caregiver/study partner, who agrees to support the participant through the GOAL program. Participant and caregiver are not required to live together
• Mini Mental State Examination (MMSE) score >24 The participant should present a mild cognitive impairment (MCI) in absence of secondary causes of dementia (hypothyroidism untreated or treated with a therapy that has been revised in the previous 6 months, vitamin B12 or folate deficiency), assessed through a blood test.

In case of MCI due to Alzheimer Disease (AD), additional inclusion criteria are:

• Hachinski Ischemic Score ≤4
• Absence of secondary causes of dementia confirmed by a neuroimaging examination (TC scan or encephalic MRI), Fazekas score <2
• Biomarker of neuronal damage (PET with 18f-fluorodeoxyglucose, MRI with hippocampal volumetric assessment or levels of t-tau and p-tau in the cerebrospinal fluid) or biomarkers of Aβ deposition (Amyloid-PET or levels of A> 42 in the cerebrospinal fluid) consistent with MCI due to AD

In case of MCI due to Vascular Cognitive Impairment, additional inclusion criteria are:

• Hachinski Ischemic score > 4
• Fazekas score >=2
• Presence of at least one of the following conditions, as assessed by TC scan or encephalic MRI

• Multiple lesions in the white matter consistent with cerebral small vessel disease
• Lacunar status
• Multi-infarct encephalopathy with ischemic multiple lesions in the cortical region, in the basal ganglia and white matter

Exclusion criteria

• Unreliable communication (eg, foreign language or aphasia)
• Severe visual or auditory deficit, not reversible, to the extent that it compromises the interaction with the operator and the usage of ICT instrumentation.
• Presence of neurological and/or psychiatric disorders (Hamilton scale >12) that might interfere with cognitive status
• Left-handed individuals
• Level of education <3 years
• History of substance abuse (nicotine excluded)
• Having relapsing systemic disease and presence of major head trauma

• Frank dementia
• MMSE <24
