[Age and gender aspects of attention-deficit hyperactivity disorder].

Attention-deficit hyperactivity disorder (ADHD) is a syndrome with onset in childhood which persists at least partially in about 60% of afflicted individuals. Core symptoms include inattention, hyperactivity, and impulsivity. Additional psychopathology with disorganized behavior and emotional dysregulation is common in adulthood. The vast majority of adults affected also present psychiatric comorbidities. There is severe impairment of everyday life and quality of life. Developmental psychopathologic changes, age-related comorbidity, and functional and psychosocial problems associated with ADHD must be taken into account during the diagnostic process. Regarding clinical subtypes of ADHD according to DSM-IV and particularly gender differences, knowledge about these factors in adults with ADHD is limited.
