Attention-Deficit/Hyperactivity Disorder (ADHD) is a common childhood disorder that can continue through adolescence and adulthood. Symptoms include higher than normal levels of impulsivity and inattention that impair an individual's ability to function properly in various settings like school or work. Studies show a greater number of boys being diagnosed with ADHD compared with girls, with male to female ratios reported to range from 3:1 to 9:1, dependent on the study setting (general population or clinics). There are three distinct subtypes of ADHD: predominantly inattentive type (ADHD-I), predominantly hyperactive-impulsive type (ADHD-H), and combined type (ADHD-C). Common comorbidities include learning disabilities, oppositional defiant disorder, conduct disorder, obsessive compulsive disorder, tic disorders, substance use disorders, anxiety disorders, bipolar disorder, and depression. Genetic studies have conclusively demonstrated that genetic influences play a role in the etiology of ADHD. Order a copy of this report @ http://www.reportsnreports.com/purchase.aspx?name=752985 .
