Evaluating Multifocal Non-Invasive Brain Stimulation and Cognitive Training to Improve Symptoms in Mild Cognitive Impairment and Early Dementia

What this Trial Is About

Researchers are evaluating whether a combined approach using multifocal non-invasive brain stimulation and brain recording with cognitive training can help reduce cognitive and emotional symptoms in people with mild cognitive impairment and early dementia. The study aims to understand if this treatment affects cognition and depression symptoms, and how factors like education and cognitive reserve influence outcomes. It also investigates brain activity measures to identify who responds best to the treatment. Participants will receive two treatment cycles involving either real or placebo multifocal transcranial direct current stimulation tDCS over the left frontal and temporal brain areas, twice a week for two months each cycle. Along with the brain stimulation, all participants will undergo cognitive training involving exercises targeting memory, attention, and executive functions. The study uses a crossover design where each participant experiences both real and placebo stimulation cycles. During the trial, participants will complete detailed cognitive and mood assessments before treatment and after each cycle, including tests like the Montreal Cognitive Assessment and Geriatric Depression Scale. EEG brain recordings will monitor brain activity at specific sessions. Caregivers will provide information on daily living activities. The study measures changes in cognition, mood, and functional independence over an 8-week intervention period with regular evaluations.
