Abstract
ADHD (Attention deficit hyperactivity disorder) is mostly defined as a group of predominantly genetically determined neurobiological dysfunctions affecting ability to focus and sustain attention, adapt the activity requirements of the area and control impulses. These deficits appear to be the three basic areas of ADHD symptoms: inattention, hyperactivity and impulsivity.
DSM 5 classifies it as a lifelong disorder. In 8o% of cases, the symptoms of ADHD persist into adolescence and up to 6o% of adolescents have difficulties associated with ADHD in adulthood.
Adult patients with ADHD report on inner restlessness, suffering from attentional and emotional dysregulation, disorganization and behavioral difficulties which can be derived from the impairment of executive functions. The diagnostic process of ADHD requires a comprehensive examination by a qualified professional and should include not only the current symptoms but also evaluation of academic and behavioral history from childhood to adulthood.
Psychiatric comorbidities are frequent; studies report values between 60-70%. Differential diagnosis is complicated due to the fact that many of the symptoms of ADHD can be covered with comorbid disorders: major depression, borderline personality disorder, conduct disorder, substance abuse disorders and addiction.
