Ongoing research and clinical trials about interventions and medications are constantly being conducted to explore treatments for Dyslexia, ADHD, ADD and Learning Disabilities. Find out about results of ongoing clinical trials or clincial trials looking for volunteer participants at ClinicalTrials.gov .

The Web site is maintained by the National Library of Medicine at the National Institutes of Health (NIH). Information on ClinicalTrials.gov is provided and updated by the sponsor or principal investigator of the clinical study. Studies are generally submitted to the Web site (that is, registered) when they begin, and the information on the site is updated throughout the study. In some cases, results of the study are submitted after the study ends. This Web site and database of clinical studies is commonly referred to as a "registry" and "results database." ClinicalTrials.gov includes information about medical studies in human volunteers. Most of the records in ClinicalTrials.gov describe clinical trials (also called interventional studies). A clinical trial is a research study in which human volunteers are assigned to interventions (for example, a medical product, behavior, or procedure) based on a protocol (or plan) and are then evaluated for effects on biomedical or health outcomes. ClinicalTrials.gov also includes records describing observational studies and programs providing access to investigational drugs outside of clinical trials (expanded access). ClinicalTrials.gov does not contain all clinical studies conducted in the United States because not all studies are required by law to be registered, such as observational studies and trials that do not study a drug, biologic, or device (see FDAAA 801 Requirements for more information). However, the rate of registration has increased over time as more policies and laws requiring registration have been enacted and as more sponsors and investigators voluntarily register their studies. ClinicalTrials.gov was made available to the public on February 29, 2000 and the results database was released in September 2008. Once a study is registered on the site, it is not removed. The full history of changes made to a record can be accessed by viewing the archival version of the record on the ClinicalTrials.gov archive site. Searching ClinicalTrials.gov does not require registration or personal identification. Because ClinicalTrials.gov is a government Web site, it does not host, or receive funding from, advertising or the display of commercial content. Each ClinicalTrials.gov record presents summary information about a study protocol and includes the following: • "Disease or condition • "Intervention (for example, the medical product, behavior, or procedure being studied) • "Title, description, and design of the study • "Requirements for participation (eligibility criteria) • "Locations where the study is being conducted • "Contact information for the study locations • "Links to relevant information on other health Web sites, such as NLM's MedlinePlus® for patient health information and PubMed® for citations and abstracts for scholarly articles in the field of medicine. • "Some records also include information on the results of the study, such as: • "Description of study participants (that is the number starting and completing the study and their demographic data) • "Outcomes of the study • "Summary of adverse events experienced by study participants • "Find and view clinical studies.
