Summary

This study will examine the possible effects of tDCS (Transcranial Direct Current Stimulation) treatment to the left DLPFC on cognitive functions which were found to be deficient amongst ADHD patients. The study will include 100 subjects, 50 of whom diagnosed with ADHD. Subjects will complete the ASRS questionnaire to measure ADHD symptoms severity. Next, subjects will complete a series of cognitive tasks, after which they will receive either tDCS treatment or a sham treatment. Finally, subjects will repeat the cognitive tasks. Later that day, a telephonic follow up will take place. ADHD symptoms will be assessed again the next day.

Conditions

• Transcranial Direct Current Stimulation

Interventions

Type	Name	Description
DEVICE	Transcranial Direct Current Stimulation	To stimulate the left DLPFC, the anode electrode will be placed over F3 and the cathode will be placed over F4. Each stimulation will be applied for 20 min at 2mA intensity.
DEVICE	Sham	For the sham treatment, stimulation will be stopped after 30 seconds. Current will be renewed five times throughout the session for 2 seconds each time, to mimic the tDCS stimulation.
