F90.2, Attention-deficit/hyperactivity disorder (ADHD), combined type, is a neurobehavioral disorder primarily diagnosed in childhood but may persist into adulthood.It is characterized by a persistent pattern of inattention and hyperactivity-impulsivity that interferes with functioning in multiple settings (home, school, work, social).Diagnosis requires the presence of at least six symptoms of inattention and six symptoms of hyperactivity/impulsivity, each persisting for at least six months, to a degree inconsistent with developmental level and negatively impacting daily functioning.Symptoms of inattention may include difficulty sustaining attention, disorganization, forgetfulness, and distractibility. Symptoms of hyperactivity/impulsivity can manifest as excessive fidgeting, interrupting others, difficulty waiting one's turn, and excessive talking. Treatment typically involves a combination of medication (stimulants, nonstimulants, or antidepressants depending on age and presentation), behavioral therapy, and other supportive interventions.

Example 1: A 9-year-old boy presents with significant difficulties in school, including inattention during lessons, disruptive behavior, interrupting classmates frequently, and difficulty completing assignments. He also exhibits hyperactivity, including excessive fidgeting and restlessness. His teacher and parents report similar behavior at home., A 25-year-old adult reports a lifelong history of difficulty focusing at work, impulsivity leading to poor decision-making in finances, and problems with maintaining relationships.They also experience significant restlessness and difficulty relaxing., A 15-year-old girl is referred for evaluation due to academic underachievement, despite average intelligence.
