This may include stealing, intentional injury, and forced sexual activity. This disorder is the often a precursor for Anti-Social Personality Disorder in adulthood. Impairments in motor skills, social skills, modulation of emotional response, and response to rewards and consequences are common. One fourth of ADHD children have a significant anxiety component and a fifth with clinical depression. The ADHD often has a low self-esteem contributed by the frequent negative feedback from parents, teachers, and peers.
Depression certainly complicates ADHD, exacerbating pre-existing symptomatology.
Both disorders in children can present with hyperactivity, dangerous impulsive play, oppositionality, defiance, and irritability. However, ADHD is common and Bipolar Disorder relatively rare in children, with an incidence less than a small fraction of a per cent. The key to differentiating the two is that ADHD is chronic and Bipolar Disorder periodic, i.e. there will be usually long time intervals during which a child will do well without interventions. Children with ADHD have a higher percentage of tics than otherwise. Tics are extraneous movements like eye blinks or facial twitches that they cannot control.
