Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 14 to 79 years
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: The experimental group will consist of adults with autism (n=40). Participants will be 18-79 years of age, diagnosed with autism by independent clinicians and confirmed by formal assessment (e.g., CDI, ADOS, Bayley, Sensory Profile), and with receptive and expressive vocabulary levels of ≥ 3 years age-equivalent, as assessed by standardized measures. Additionally, the Autism Diagnostic Interview will be administered to caregivers in order to appropriately identify specific areas (regarding speech, language and cognition) in which participants are experiencing the most difficulty.

Who may be able to join

  • Clinical diagnosis of autism or related conditions
  • Identified language deficit(s) and/or other cognitive or behavioral impairments (which will be specific to each sub-study)
  • Adequate ability to perform the research tasks set for the individual's particular level of performance

Who cannot join

  • Peripheral blindness or deafness
  • Any implanted metal device (precludes use of tDCS)
  • Any implanted cardiac pacemaker

About this study

Official title: The Use of Transcranial Direct Current Stimulation (tDCS) to Improve Communicative Efforts, Speech, Language and Related Cognitive Functions in Individuals With Autism

This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve certain mental abilities, such as speech, language and other efforts at communication in individuals with autism.

In this research, battery powered device is used to deliver very weak electrical current to the surface of the scalp while participants are involved in tasks aimed at training or measuring communicative efforts, speech, language or related cognitive functions. Our aim is to find out whether tDCS will improve these mental abilities.

Read the detailed description

Participants in the study will be asked to do the following things:

  • Grant permission for the researchers to view medical/psychological and/or educational and/or speech records associated with the diagnosis of low-functioning autism.
  • Complete a questionnaire and provide a health history.
  • Complete evaluations by our study team to assess the diagnosis and gain a clearer understanding of the participant's current functioning.
  • Give permission to audio and video-tape test sessions for later scoring and observation.
  • Give permission to audio or video-tape in the classroom or home environment using non-intrusive audio-visual recording devices.
  • Complete several tasks and training interventions that involve such things as learning new words or pictures, saying words out loud, or naming objects.
  • Participate in an eye tracking study while completing a task on the computer which involves wearing a headband, attached by a velcro fastener, which contains a magnetic sensor. This equipment allows us to track the position of the head in order to record more accurate measurements. It is used with eye tracking equipment which measures the gaze on a set point on a computer screen. The equipment poses no risk and is non-invasive.
  • Participate in computerized tasks while monitoring brain responses that are a direct result of a thought or perception. In order to monitor these responses, electrodes would be placed over various points on your scalp. The electrodes will record the on-going activity of the brain; it does not produce or introduce any electrical activity. The equipment poses no risk and is non-invasive.
  • Wear electrodes that will be placed on the scalp with a large rubberized band. These electrodes will administer very weak electrical current (tDCS) from a battery powered device for 20 to 60 minutes.

The experimental sessions will last about 1 hour and participants may be asked to have more than one testing session in a day or to return for additional sessions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Picture naming accuracy

    Oral naming of visually-presented pictures, measured in terms of accuracy. (Note: this task may not be included in the final design, nor given to all subjects)

    Measured: 10 minutes

  2. Picture naming speed

    Oral naming of visually-presented pictures, measured in terms of speed (milliseconds). (Note: this task may not be included in the final design, nor given to all subjects)

    Measured: 10 minutes

Questions about this trial

What is this clinical trial studying?

An observational study of Autism Spectrum Disorders, run by Johns Hopkins University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Picture naming accuracy (time frame: 10 minutes). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2023.
