Abstract
Introduction: The aim of the present study was to investigate the effect of transcranial stimulation of different brain areas on the working memory and attention of the elderly.
Methods: The present study is a quasi-experimental study with a pretest-posttest design. The statistical population of the present study included elderly people aged 60-70 years in Mashhad. For this purpose, 72 people were selected using the available and purposive sampling method and after obtaining written consent, they were randomly assigned to one of six groups: cerebellar tDCS stimulation and cerebellar sham, dorsolateral prefrontal tDCS stimulation and dorsolateral prefrontal sham, primary motor cortex tDCS stimulation and primary motor cortex sham. The tools used in this study were the Cambridge Neuropsychological Assessment Test Automated Battery (CANTAB) scale and the tDCS device. The pretest of the working memory and attention scale was taken from the subjects. Then, stimulation was performed in the aforementioned areas for 2 weeks, 5 times a week, and for 20 minutes. After the intervention, the posttest of the working memory and attention scale was taken from the subjects again. The data was analyzed using the statistical method of analysis of covariance.
Results: The results of this study showed that there was a significant difference between the effects of tDCS stimulation conditions on the working memory and attention of the elderly; this difference was in favor of the cerebellar tDCS group (sig=0.001).
