About this study

The purpose of this study is to investigate the association of adverse environmental factors, parental psychopathology, family functioning and genetic factors and the response to methylphenidate treatment in children and adolescents with Attention Deficit/Hyperactivity Disorder.

Read the detailed description

Attention Deficit/Hyperactivity Disorder (ADHD) is a chronic disorder, with a worldwide estimated prevalence of 5,29%. It is associated with a high risk of functional impairment in many aspects of the patient´s life, such as academic achievements, peers relationships and physical injuries. There are few studies assessing predictive factors of clinical response to treatment. Different patterns of family functioning, such as high family conflict and low family cohesion might be associated with a poor treatment response, possibly mediating the effects of higher severity af the disorder and/or higher prevalence of comorbidity. Parental psychopathology has been associated with a poorer prognosis and is related with family functioning. Adverse social factors have long been studied and are associated with an increased risk for general mental disease, including ADHD, as well as a poorer prognosis. Different genetic factors have been studied and associated with different aspects of the disorder and different clinical responses to treatments. There are no studies evaluating how those factors interact with each other in a Brazilian population.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Methylphenidate in people with Attention Deficit Disorder With Hyperactivity, run by Federal University of Rio Grande do Sul 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 3 inclusion and 2 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 17 Aug 2009. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

SNAP -IV scores (time frame: 1, 2, 3 and 6 months of treatment). 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 17 Aug 2009.
