The effect of Transcranial Direct Current Stimulation(TDCS)on cognitive problems in children and adolescents with attention deficit hyperactivity disorder

Determining the effect of cranial direct current stimulation (TDCS) on the cognitive problems of children and adolescents with attention deficit hyperactivity disorder

A clinical trial with a control group, double-blind, phase 3, on 44 patients. which random number table was used for randomization

Children and adolescents with ADHD referred to the clinic are included in the study. After obtaining informed consent, they are divided into intervention and control groups based on the random number table. In the first session, n-back, stroop and digit recall tests are performed for all patients. The intervention group, in addition to drug treatment, is treated for 10 sessions. tDCS is administered with an intensity of 1 milliamperes for 20 minutes, and in the sham control group, tDCS is added as a placebo to drug therapy. In the last session, all children and teenagers will be tested with stroop, n-back and digit span tests.

44 children and adolescents with ADHD, their age is between 7 and 18 years, their IQ is more than 80, and it has been 3 months since their drug treatment, and they have good compliance and cooperation, were included in the study. Exclusion criteria include IQ, having a pacemaker, having a history of ECT and tDCS, having a history of seizures and facial-cranial deformity.

Intervention group: tDCS sessions with an intensity of 1 mA andal in the left frontal area for 20 minutes and 2-3 sessions per week. Control group: sham tDCS sessions in the same area and the same number of sessions with the same duration as the tDCS group.

Investigating the effect of tDCS on cognitive problems including executive functions, working memory and attention in children and adolescents with ADHD

For the random allocation of cases to two groups A and B according to the number of interventions, blocks of four were considered. By using the sealed envelope site, blocks were created and a random sequence of blocks was created. The sequence created is shown below. created were assigned to the groups. A closed envelope was used to hide the allocation. After entering the plan and signing the consent form, the patients received the envelope and went to the clinic to perform the test. Only the person performing the test of the type of test Done was aware. Block sizes: 4 Actual list length: 44 block identifier, block size, sequence within block, treatment

The study is a two-way blind study, the shape of the device, the intensity of the applied current and the duration are the same in both tDCS and sham groups. The patient and their clinical caregiver and the analysts are not aware of what treatment they have undergone and the intervention of tDCS or The sham is applied with the help of the project's associate psychologist

The total individual participants' data and the results of the study after the deidentification of the individuals are shared.
