Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study will investigate the effect of 20 min of 2mA anodal transcranial direct current stimulation (tDCS) in combination with 45 min of standard occupational therapy in 20 children diagnosed with mild to moderate attention deficit hyperactivity disorder. Children will undergo 10 weekly consecutive sessions of their standard occupational therapy of which 5 consecutive sessions of active and 5 consecutive sessions of sham tDCS will be randomly assigned by employing a double-blind cross-over design. The standard occupational therapy will be administered by an occupation therapist while the tDCS will be performed by qualified research staff.
Intervention code [1] 290705 0
Treatment: Devices
Comparator / control treatment
Randomised trial of sham versus active stimulation in a double-blind cross-over procedure. The current on- and offset of tDCS usually creates a tingling sensation over 30 seconds at the beginning of the stimulation. Only receiving the stimulation for 30 seconds will create the same sensation and will be used for 5 consecutive sessions as sham stimulation.
Control group
Placebo

Outcomes

Primary outcome [2] 293795 0
Changes of impulsivity will be assessed by the results of a stop-signal task and compared between active versus sham stimulation
Timepoint [2] 293795 0

Summary
Brief summary
Applying a mild electrical current to the head is known to improve brain functions related to attention and learning without causing significant adverse side effects other than a mild local skin irritation at the stimulation site. The current study investigates stimulation effects whilst children - diagnosed with mild to moderate attention deficit hyperactivity disorder - undergo their regular occupational therapy.
