Description

After informed consent, a structured clinical interview for DSM-5-TR will be conducted using the "Emotional Disorders and Schizophrenia Form for School-Age Children - Current and Lifetime Form DSM-5 - Turkish Adaptation (ÇDŞG-ŞY-DSM-5-T)". The "Sociodemographic and Clinical Data Form" created by the researchers will be completed to obtain sociodemographic and clinical data for the participants. The "Conners Parent Rating Scale-Revised Short Form" and "Conners Teacher Rating Scale-Revised Short Form" will be administered to the group diagnosed with ADHD to determine the severity of the disease, symptoms, and predominant subtypes. After the diagnosis is made and evaluated according to the exclusion criteria, peripheral venous blood will be collected in yellow-capped tubes between 9 and 12 a.m. after a 10-12 hour fast, prior to the routine planned methylphenidate treatment. After being left at room temperature for 10-20 minutes, the blood will be centrifuged at 3000 RPM for 20 minutes, and the serum portion will be collected into Eppendorf tubes and stored at -80 degrees until the samples are analyzed. Three months after starting treatment, blood will be collected and stored in the same manner. After all samples have been collected, the serum samples will be analyzed in a single batch for Interleukin-6 (IL-6), S100B, and Claudin-5 levels using human ELISA kit protocols at the Medical Biochemistry Laboratory of Bakırköy Dr. Sadi Konuk Training and Research Hospital by biochemistry specialist Dr. Hacer Eroğlu İçli. Three months after the start of treatment, the Conners Parent Rating Scale - Revised Short Form and the Conners Teacher Rating Scale - Revised Short Form will be administered again.
