In simple words: Predominantly hyperactive-impulsive type of attention deficit hyperactivity disorder (ADHD) is a mental health condition, mainly present in children, marked by excessive activity and impulsiveness for over six months. This impacts their daily routines at home, school, and social interactions.Kids with this type of ADHD have trouble sitting still, interrupting, and paying attention. While no cure exists, treatments like medication and therapy can help manage symptoms.

This condition, primarily affecting children, involves excessive hyperactivity and impulsivity lasting more than six months. Symptoms include impatience, fidgeting, inability to play quietly, excessive talking, difficulty focusing, disorganization, forgetfulness, interrupting others, and intrusiveness. Diagnosis requires meeting specific criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders. Treatment can include medication (stimulants, non-stimulants, or antidepressants), behavioral therapy, family/group therapy, skills training, and stress management.

Example 1: A 7-year-old boy constantly fidgets in class, interrupts the teacher, and has difficulty completing tasks. He struggles to wait his turn and often acts impulsively., A 10-year-old girl talks excessively, has difficulty playing quietly, and frequently leaves her seat during class. She struggles with organization and forgetfulness., An adult diagnosed with ADHD in childhood continues to experience hyperactivity and impulsivity, impacting their work and relationships.

Documentation should include detailed observations of the individual's behavior at home, school, and social settings.It should also describe the duration and severity of symptoms, impact on daily life, and any previous interventions. Medical history, clinical assessments, and interviews with parents, teachers, and other relevant individuals should also be documented.

** It's important to distinguish F90.1 from other subtypes of ADHD, such as predominantly inattentive type (F90.0) and combined type (F90.2).The predominantly hyperactive-impulsive presentation is characterized by a more pronounced display of hyperactivity and impulsivity, with less emphasis on inattention symptoms.
