Mit akar kideríteni a vizsgálat

Autism Spectrum Disorder (ASD) is a pervasive neurodevelopmental disorder that currently affects 1 in 32 children. ASD is characterized by persistent deficits in social communication and restricted, repetitive behaviors. For instance, people with ASD often show great difficulty in recognizing social cues and understanding others' emotions, as well as having a tendency to act inflexibly and inappropriately in social situations, all of which contribute to lifelong social and occupational dysfunctions.To date, there is no cure for ASD. Existing treatments are primarily behavioral or educational based. Although some treatments show positive therapeutic effects in reducing patients' core autistic symptoms, the interventions are often labor- and time-intensive. Recently, a non-invasive painless brain stimulation technique, "transcranial direct current stimulation (tDCS)," has received increasing interest in clinical settings as a potential tool for cognitive enhancement and neurorehabilitation for various cognitive dysfunctions. This study aims to examine the effectiveness of tDCS treatment combined with cognitive training for individuals with ASD. We will study the effect before and after treatment.

A vizsgálat 2 csoportja

• Active-tDCSA vizsgált kezelés

  For the active-tDCS condition, participants will receive a stimulation on the dorsolateral prefrontal cortex, with ramp up and ramp down mode for 30 seconds, eliciting a tingling sensation on the scalp that fades over seconds.

  Kezelés: Active-tDCS with computerized cognitive training

• Sham-tDCSSzínlelt kezelés, összehasonlításként

  For sham-tDCS condition, participants will receive an initial stimulation of a ramp up and ramp down mode for 30 seconds, eliciting a tingling sensation on the scalp. Then the stimulation will be discontinued.
