Summary

Alzheimer's disease (AD) is characterized by a progressive decline in cognitive functions, interfering with autonomy and independence. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM 5), mnemonic dysfunction in AD must be related to aphasia, apraxia, agnosia, or changes in executive function. The clinical picture of the disease can be described as mild, moderate and severe. In the mild phase, the patient is disoriented and with difficulties in thinking, in later stages memory lapses become more intense and frequent. The symptoms of apraxia, aphasia and agnosia appear, causing a noticeable impact on the performance of simple daily activities, and neuropsychiatric and behavioral symptoms are expressed. Existing pharmacological treatments for AD treatment are able to minimize the symptoms of the disease, but are not able to promote cure. Therefore, studies have sought to better understand non-pharmacological strategies, aiming at optimizing the benefits of using the drug. Studies have suggested that tDCS promotes significant effects on cognitive processes assessed through cognitive tasks, not only in healthy individuals but also in clinical populations. Cognitive training (TCog) has similarly shown excellent results in the treatment of cognitive deficits due to AD. Thus, the present study aims to investigate when (before, during or after) the tDCS should be applied to potentiate the effects of TCog in people with AD by comparing four protocols of application of neurostimulation associated with TCog.

Conditions

  • Alzheimer Disease

Interventions

OTHER

tDCS associated with Tcog

2mA-intensity aETCC will be applied to the left dorsolateral prefrontal cortex (CPFDL) region for 20 min, three times a week (every other day) over a one-month period, totaling 12 sessions. In each session activities aimed at stimulating cognition will be applied over the 20 minutes.
