Role of Transcranial Direct Current Stimulation (tDCS) in Patients With Attention Deficit Hyperactivity Disorder (ADHD)

Role of Transcranial Direct Current Stimulation (tDCS) in Patients With Attention Deficit Hyperactivity Disorder (ADHD)

The purpose of this study is to determine whether transcranial direct current stimulation (tDCS) is effective in the treatment attention deficit hyperactivity disorder (ADHD).

Randomized, double-blind Controlled Clinical Trial

Subjects Adults (between 18 and 59 years of age) with ADHD who meet the inclusion criteria and who agree to participate in the study Will recruit from advertisements and clinical referrals to a PRODAH

Active tDCS Anode - right DLPFC Cathode - left DLPFC Electric current is 2mA - Current is applied for 20 min

Sham tDCS Same assembly is used Current is applied for 30 sec

Both groups 5 stimulation sessions on consecutive days

Following tools at Baseline, 1st week, 2 st week, 3st week and 4st week Adult ADHD Self-Report Scale (ASRS) SDS - Sheehan Disability Scale CGI - Clinical Global Impression
