Attention deficit hyperactivity disorder
When diagnosed in adults, presenting symptoms include inattention, restlessness, and impulsivity, but also involve emotional dysregulation (angry outbursts, low threshold of frustration), and executive dysfunction (trouble organizing and completing tasks, missing appointments or deadlines). Hoarding symptoms may be present in up to 25% of adults with ADHD.
Management of ADHD involves treatment of coexisting psychiatric, medical, or neurologic disorders, behavioral and pharmacologic interventions, psychotherapy, counseling, and family support. Clinicians should screen for bullying, as intervention can decrease the risk for future psychiatric symptoms.
A 2018 study has shown that in states with an age cutoff at September 1 for kindergarten entry, children born in August were significantly more likely to receive a diagnosis of ADHD than children born in September.
