Attention deficit hyperactivity disorder
Attention deficit hyperactivity disorder (ADHD) is a "behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood."[1][2][3]
ADHD occurs in adults also.[4]
There are significant adverse socioeconomic outcomes from ADHD.[5][6]
Etiology/cause
Twin studies suggest 76% of ADHD is inherited.[7] Abnormalities of biogenic amine receptors may contribute to ADHD.[7]
The relationship between childhood bipolar disorder and attention deficit hyperactivity disorder is uncertain.
Treatment
Several stimulant drugs are effective.[8] Stimulant drugs work by blocking the dopamine transporter.[2] However, these drugs may increase cardiac complications.[9]
