Clinical Trial Summary

Background: Transcranial direct current stimulation(tDCS) has been used to improve cognitive functions in healthy young adults.

Purpose: To investigate the effect of TDCS application on different cortex regions on cognitive function.

Methods: Sixty individuals aged 18-30 were included in the study. The participants were randomly divided into the left dorsolateral prefrontal cortex (Left DLPFC Group)(n=20), the right posterior parietal cortex (Right PPC Group)(n=20), and the sham group (Sham Group)(n=20). tDCS was applied for 20 minutes on weekdays for 2 weeks. The participants were evaluated in terms of cognitive functions with Neuropsychometric Test Battery before and after treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Neuropsychiatric Test Battery	It is a test battery for getting detailed information about general cognitive status.	3 weeks
Primary	Beck Depression Scale	It measures the symptoms seen in depression such as emotional, cognitive and motivational. It includes 21 items determine a behavioral feature related to depression. Items are numbered from 0 to 3. The goal is to objectively break down the degree of symptoms.; The total score of all answers is calculated as follows: 0 to 9 points: Minimally depressive symptoms 10 to 16 points: Mild depressive symptoms Between 17 and 29 points: Moderate depressive symptoms Between 30 and 63 points: Severe depressive symptoms	3 weeks
