Study Description

The aim of this study is to determine whether the effectiveness of the home-based therapy program "Attexis" can be augmented with another home-based procedure, tDCS treatment, in order to achieve even higher improvement rates in the treatment of ADHD in the future. Before the actual start of treatment with Attexis, the presence of an ADHD diagnosis (ICD-10: F90.0) is checked by qualified medical staff at Medbo Regensburg. If the screened patient then meets the other inclusion criteria for Attexis and tDCS, he or she will be randomly assigned to either the intervention group (receives access to both Attexis and tDCS) or the placebo group (receives access to both Attexis and placebo tDCS). Based on the study by Schlechter et al. (2023), it is planned to treat patients receiving (placebo) tDCS treatment with 60 sessions (2mA, 20 minutes per day) by stimulating the left DLPFC. As patients will have a three-month access to Attexis, it is planned to administer the additional (placebo) tDCS treatment at the same time. As soon as a patient registers for the study, the safety aspects and inclusion/exclusion criteria for tDCS treatment are also checked in an initial interview after the ADHD diagnosis has been verified. The patient is then randomly assigned to one of the two study arms. A suitable appointment is then arranged for the patient to be admitted to the device. About 60 minutes are scheduled for the explanation and instruction of the tDCS device. During the appointment, an initial trial treatment is carried out so that the patient can get used to the treatment. All subsequent home-based treatments are carried out from Monday to Friday (each lasting 20 minutes) with video observation during the first week of treatment. For the sessions via teletherapy, software approved for clinical use (CLICKDOC version 5.9.1, La-Well Systems GmbH, CompuGroup Medical SE & Co. KGaA, Bünde, Germany) is to be used. At the end of the tDCS treatment, a final consultation will be arranged, which will take about 45 minutes. A follow-up (clinical ratings and attention test) will be carried out after 3 months.
