Neuropsychological and Neurophysiological Effects of Cognitive Stimulation in Patients With Alzheimer's Disease and Mild Cognitive Impairment
December 20, 2018 updated by: Carlo de Lena, University of Roma La Sapienza
A Randomized, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy of a Non-Pharmacological Intervention of Cognitive Stimulation in Subjects With Alzheimer's Disease and Mild Cognitive Impairment: The Brain Stimulation Project.
The present study aims to evaluate the effect of cognitive stimulation (CS) in participants with a diagnosis of moderate and mild Alzheimer's disease (AD) and mild cognitive impairment (MCI) compared to control subjects not receiving any non-pharmacological interventions.
Treated participants will receive a structured CS consisting of a wide range of activities aimed at the general improvement of social functioning and the maintenance of cognitive functions.
The study consists of a 24-week treatment phase and a follow-up period of 24 weeks.
During the treatment period, patients will receive two CS sessions a week.
At baseline, all the participants undergo an extensive neuropsychological evaluation and a neurophysiological assessment aimed at studying the frequency of spontaneous blinking (blink rate) and cortical excitability and synaptic plasticity by means of the transcranial magnetic stimulation (TMS).
Neuropsychological and neurophysiological evaluations will be repeated at the end of the treatment (week 24) and at the end of the follow-up period (week 48) in order to evaluate short- and long-term effects of CS.
The hypothesis of this research is that CS may improve cognition and the neurophysiological parameters studied in treated participants compared to those untreated.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: moderate AD-experimental
Experimental Intervention: The CS shall be carried out in groups (5-7 participants), twice a week.
Each session lasts 90 minutes.
CS sessions begin with a training for temporal and spatial orientation in which participants are asked to recognize and recall the date and the place with the help of some environmental aids (calendars, clocks, pictures and maps).
Then the participants complete an array of cognitive tasks for memory, attention, language, visuo-spatial functions and executive functions.
These tasks range from individual paper-and-pencil exercises to verbal-learning exercises that have to be solved by the group.

CS consists of a wide range of structured activities aimed at the general improvement of social functioning and the maintenance of different cognitive functions.
It is a non-specific in-group approach that places particular emphasis on social interactions.

Experimental: mild AD-experimental
Experimental Intervention: the same of the "moderate AD-experimental" arm

The extent of facilitatory-Paired Associative Stimulation-induced effects on MEP amplitude ranges from 120% to 160%, while inhibitory-Paired Associative Stimulation may induce a reduction of muscle-evoked potential amplitude that ranges from 60% to 90%.
