Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

This study will investigate the effects of methylphenidate on sleep in adults with Attention Deficit/ Hyperactivity Disorder (ADHD) using polysomnographic parameters.

This study will consist of a six-week open-label treatment period with an extended duration methylphenidate (OROS MPH) followed by subsequent monthly visits for 24 months in a large sample of youths aged 12-17 who meet Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for ADHD. The researchers hypothesize that OROS MPH treatment will be associated with low rates of cigarette smoking in ADHD youth.

The purpose of this study is to compare the safety and efficacy of two doses of dexmethylphenidate to two doses of an approved, long-acting, marketed medication for ADHD (MPH) and placebo in children ages 6-12 diagnosed with ADHD.

The relationship between brain volume and sensory integration in children and adolescence with attention deficit hyperactivity disorder and autistic spectrum disorder; comparative study

The primary aim of this study is to assess the predictability of treatment response to stimulants in adults with ADHD using functional magnetic resonance This study will be a six-week, open-label study including adults ranging from age 18-55 with ADHD.

The purpose of this study is to establish a new Chinese children's speech and language norm by obtaining the latest data of speech and language development of children aged 2 ~ 6 from different regions in China. At the same time, the overall development level and group differences of speech and language in Chinese children aged 2 to 6 years, and the influencing factors of speech and language development in Chinese children aged 2 to 6 years were also discussed.

This study is designed to test if the medical-education-community collaborated intervention can reduce the symptoms of children with Attention deficit hyperactivity disorder (ADHD) compared to routine clinical care. Investigators will also evaluate if the intervention will positively affect organizational skills and academic achievement compared to controls.
