The goal of this clinical trial is to learn if an integrated protocol using multifocal non invasive brain stimulation and brain recording combined with cognitive training is effective in treating cognitive and affective symptomatology in patients with mild cognitive impairment and early stages of dementia. The main questions it aims to answer are:

The global prevalence of dementia is expected to continue to rise. Recent estimates forecast that the number of people with dementia worldwide will increase to 152 million cases in 2050. This calls for the development of effective prevention and treatment strategies. Recently, the benefits of non-pharmacological interventions for the intervention in dementia and its preclinical conditions are being explored. Within this contex, transcranial direct current stimulation (tDCS), represents a safe and straightforward approach to modulate brain excitability with the potential to reduce symptomatology in individuals with dementia and Mild Cognitive Impairment (MCI).
The objective of this study is to evaluate a protocol for the treatment of the cognitive and affective symptoms in dementia and MCI with several specific novel features.
First, the protocol adopts multifocal stimulation of relevant brain structures involved in the genesis of the symptoms. While previous studies focused on specific areas in the frontal and temporal cortex in separate treatment conditions, the present study employes multifocal tDCS over such structures to strengthen distribution of direct current over the left fronto-temporal network, and to possibly boost the achievable outcomes.
Second, to address the issue of heterogeneity of stimulation effects, the study combines electrophysiological measures (EEG) with brain stimulation to monitor the effect of brain stimulation following specific polarities, also considering possible individual differences in response to stimulation. Such a protocol would allow identifying responders (and non responders) to stimulation, thus targeting individuals which may benefit (or not) from a given intervention.
Third, the study will further explore the variability in response to brain stimulation raised by previous studies, considering the relationship between some demographic and psychological factors with clinical and electrophysiological outcomes. Previous studies have shown a buffering effect of age and education on global cognitive response following brain stimulation, and a relevant association of cognitive functioning with cognitive reserve. The contribution of these variables will be explored in the study to provide a more complex interpretation of either positive or null effects associated with the intervention.

Real multifocal tDCS will be delivered with an intensity of 2.0 mA over 8 electrodes positioned over the frontal and temporal areas in the left hemisphere according to the international 10/10 EEG system. The overall duration of stimulation will be set at 20 minutes.
Also known as: transcranial Direct Current Stimulation
Sham multifocal tDCS will be delivered with an intensity of 2.0 mA over 8 electrodes positioned over the frontal and temporal areas in the left hemisphere according to the international 10/10 EEG system. The overall duration of stimulation will be set at 30 seconds.
Also known as: transcranial Direct Current Stimulation
During the two cycles, all participants will undergo traditional cognitive stimulation therapy, involving paper-and-pencil exercise and computerised activity on several cognitive domains including memory, attention, and executive functions (duration 30-40 minutes) .
Montreal Cognitive Assessment (MOCA; Santangelo et al., 2015).
MOCA is a brief neuropsychological tool for screening global cognitive functioning specifically designed for MCI and early stages of dementia. The score ranges 0-30; the higher the score the higher the level of general cognitive functioning.
Time frame: The test will be used to monitor cognitive functions before the first cycle (T1, at week 0) and at the end of the first (T2; at week 4) and second cycle (T3; at week 8) of the intervention. Each cycle is 28 days.
Frontal Assessment Battery (FAB; Appollonio et al., 2005).
FAB is a screening neuropsychological battery for evaluation of executive functioning. Total score ranges 0-18; the higher the score, the higher the level of executive functioning.
Time frame: The test will be used to monitor cognitive functions before the first cycle (T1, at week 0) and at the end of the first (T2; at week 4) and second cycle (T3; at week 8) of the intervention. Each cycle is 28 days.
Free and Cued Selective Reminding Test (FCSRT; Frasson et al., 2011).
FCSRT is a neuropsychological tool designed to assess episodic memory domain. The test provides separate scores for free, cued and total immediate recall (scores 0-36), and scores for free, cued and total delayed recall (scores 0-12); the higher the scores, the higher the memory performance
Time frame: The test will be used to monitor cognitive functions before the first cycle (T1, at week 0) and at the end of the first (T2; at week 4) and second cycle (T3; at week 8) of the intervention. Each cycle is 28 days.
Stroop Colour and Word Test (Caffarra et al., 2002).
The Stroop Test is a neuropsychological test assessing cognitive interference and inhibition. The test provides two measures, i.e. overall number of errors and time to complete the test, with lower scores indicating better performance.
Time frame: The test will be used to monitor cognitive functions before the first cycle (T1, at week 0) and at the end of the first (T2; at week 4) and second cycle (T3; at week 8) of the intervention. Each cycle is 28 days.
Geriatric Depression Scale (GDS; Galeoto et al., 2018).
GDS is an evaluation tool to diagnose older adult's depression. This questionnaire is designed for the older person and defines his/her degree of satisfaction, quality of life, and feelings. The total score ranges 0-30 with higher scores indicating higher levels of depression.
Time frame: The test will be used to monitor affective symptoms before the first cycle (T1, at week 0) and at the end of the first (T2; at week 4) and second cycle (T3; at week 8) of the intervention. Each cycle is 28 days.
EEG Power Spectrum
EEG data will be separated into two-second epochs after they are cleared of noise. Power spectrums of these data will be obtained in the delta, theta, alpha, beta and gamma frequency bands. Each epoch will be analyzed by Fast Fourier Transform (FFT, Fast Fourier Transform). Maximum peaks will be determined in the delta (0.5-3.5 Hz), theta (4-7 Hz), alpha (8-13 Hz), beta (15-28 Hz) and gamma (28-48 Hz) frequency bands. These values will be used in statistical analysis for each person and electrode.
Time frame: EEG recordings will be performed before and after the first (at week 0), eight (at week 4), ninth (at week 5) and sixtheenth (at week 8) intervention sessions. The scale will be completed by caregivers. Each intervention cycle is 28 days.
Independence in Everyday Life - ADL
Activities of Daily Living (ADL) Scale. The ADL refers to activities concerning care of one's own body, such as bathing, toileting, dressing and eating. The score ranges 0-6, with higher scores indicating higher levels of independence.
Time frame: The scale will be used to monitor symptoms before the first cycle (T1, at week 0) and at the end of the first (T2; at week 4) and second cycle (T3; at week 8) of the intervention. The scale will be completed by caregivers. Each cycle is 28 days.

The IADL refers to activities to support daily life within the home and community, such as financial management, housekeeping, shopping for groceries, making telephone calls, and taking medication. The score ranges 0-8, with higher scores indicating higher levels of independence.
