What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • tDCS activeDevice

    Stimulation will be performed with the anode placed over the right DLPFC, and the cathode placed on the left DLPFC. The applied electric current will be 2mA and is going to be applied for 20 minutes. The electrodes have a size of 35cm ² each and will be covered by sponges soaked with saline.

  • tDCS shamDevice

    For the sham tDCS, the same setting will be used. However, the current is going to be applied for only 30 seconds, not being able to induce effects on neuronal excitability.

What is being measured

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

  1. Change in scores obtained in ASRS scale.

    This scale is used to access symptoms improvement in ADHD patients, is a self repor scale.

    Measured: Autcome measure assesments: day 1 (pre-intervention), day 5 (post-intervention), 1 and 4 weeks later (accompaniment).

Secondary outcomes (2)
  1. Change in scores obtained in CGI scale.

    This scale is used to access clinical improvement in ADHD patients,

    Measured: Autcome measure assesments: day 1 (pre-intervention), day 5 (post-intervention), 1 and 4 weeks later (accompaniment).

  2. Change in scores obtained in Sheehan disability scale

    Measured: Autcome measure assesments: day 1 (pre-intervention), day 5 (post-intervention), 1 and 4 weeks later (accompaniment).

Questions about this trial

What is this clinical trial studying?

A study testing tDCS active in people with Attention Deficit Hyperactivity Disorder, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.

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 5 inclusion and 13 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 25 Feb 2016. 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 Brazil. 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. Some participants in this study may receive a placebo. 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?

Change in scores obtained in ASRS scale. (time frame: Autcome measure assesments: day 1 (pre-intervention), day 5 (post-intervention), 1 and 4 weeks later (accompaniment).). 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 25 Feb 2016.
