Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with autism (level 1 or level 2) and also adults without autism as a comparison group. It tests brain stimulation over the cerebellum.

Age
18 years or older
Sex
All sexes can join
Disease stage
For autistic adults: autism confirmed by the Autism Diagnostic Observation Schedule, DSM-5 severity level 1 or level 2. Level 3 cannot join.
Earlier treatment
Cannot join if in another clinical trial within one month, or taking drugs that raise seizure risk or antiepileptic drugs.

Main reasons for not taking part

  • Severe neurological disorders, especially epilepsy
  • Metal implants such as a pacemaker or medication pump
  • Severe psychiatric disorders or suicidal thoughts within one year
  • Pregnancy
  • Cannot have MRI or EEG

About the trial

What the trial wants to find out

This study aims to establish a personalized theta burst stimulation (TBS, an advanced variant of repetitive transcranial magnetic stimulation, rTMS) protocol considering autistic idiosyncrasy (interindividual variability).

The 2 groups in the trial

  • Autistic adultsTreatment being tested

    Eligible participants are adults diagnosed with autism who meet the inclusion criteria of the study.

    Treatment: Theta Burst Stimulation (TBS, an advanced variant of repetitive transcranial magnetic stimulation)

  • Typically developing adultsExisting treatment, for comparison

    Eligible participants are typically developing adults who meet the study's inclusion criteria.

    Treatment: Theta Burst Stimulation (TBS, an advanced variant of repetitive transcranial magnetic stimulation)

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
