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 . Click here to search: Click here to view current  trials seeking patient volunteers:  Dyslexia & ADHD Trials ClinicalTrials.gov    is   a   Web-based   resource   that   provides   patients,   their   family   members,   health   care   professionals,   researchers, and   the   public   with   easy   access   to   information   on   publicly   and   privately   supported   clinical   studies   on   a   wide   range   of   diseases and   conditions.   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.   Conduct   basic   and   advanced   searches   of   clinical   study   records;   browse   studies;   and   search studies by topic,    country, or region.
