Effects of Cathodal tDCS on Executive Functions in Autism

Status Recruiting

Clinical Trial Summary

It's an interventional, prospective and monocentric pilot study concerning adult patients with autism without mental retardation.

The primary outcome is to assess the effects of cathodal transcranial direct current stimulation (tDCS) on the left dorsolateral prefrontal cortex (DLPFC) on the executive functions of patients with autism without mental retardation or with Asperger syndrome.

The secondary outcomes are to evaluate the safety of this treatment and to evaluate its impact on impaired social communication and on restricted or repetitive behaviors.

Clinical Trial Description

The patients concerned by the study are aged 20 to 50 years old. They meet ICD-10 criteria for autism without mental retardation or Asperger syndrome and they have adaptive capacity and autonomy complaints. They stable treatments for at least 4 weeks prior and during all the study and no history of tDCS. Women of childbearing age with no adequate contraception, pregnant or lactating women are excluded.

This is an interventional, prospective and monocentric pilot study. The patient is informed about the clinical study during the psychiatric consultation. The patient is provided with a cooling-off period of several days. During the inclusion visit, the executive functions of the patient are assessed (WSCT, Stroop, TMT A and B and verbal fluency test). If 2 pathological tests are found among all measured scores: administration of ISDC and EC2R (interview of the person accompanying) and planning of the first tDCS session 15 days later. If no pathological test is found : study exit.

The treatment consists in 10 sessions of cathodal tDCS applied over the left dorsolateral prefrontal cortex (DLPFC) at 2mA. Each session lasts 15 minutes. They are 2 sessions per day.

Ten days after the end of tDCS treatment, patients are assessed for executive functions and behavioral dysexecutive functions (EC2R and ISCD). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
