The role of transcranial direct current stimulation in patients with moderate cognitive decline

Cognitive decline comes with a significant change in cognitive
performances. This change affects several cognitive domains, such as
memory, attention, executive functions, perception, language, and
psychomotor functions. The recent confirmation that neurogenesis occurs
in the adult brain lead to hypothesize that non-invasive transcranial direct
current stimulation (tDCS) might have a therapeutic potential in treating
neurodegenerative diseases. The purpose of this study was to evaluate the
effect of anodal tDCS on cognitive and neurophysiological functions inpatients with moderate cognitive impairment (MCI). Ten participants
with moderate cognitive impairment underwent ten daily sessions of 2
mA tDCS over the left frontotemporal cortex. A pre-test-post test-follow
up design was used to analyze the change in performance. Cognitive and
neurophysiological assessments were administered before and after the
tDCS sections. Results suggest that tDCS can improve cognitive and
neurophysiological performance of patients with moderate cognitive
decline
