Attention-Deficit/Hyperactivity Disorder Combined in Adults

ICD-10 code: F90.2

Attention-Deficit/Hyperactivity Disorder (ADHD) affects 30-50% of adults who had ADHD in childhood.

Approximately 5% of adults in the U.S. have some form of ADHD.

There are three types of ADHD that can occur:

  • ADHD Predominantly Inattentive Presentation
  • ADHD Predominantly Hyperactive Presentation
  • ADHD Combined Presentation
Approximately 1.1% of U.S. adults display ADHD, Combined Presentation.

These disorders are characterized by difficulty regulating attention and behavior. Symptoms are divided into two categories of inattention and hyperactivity-impulsivity. Adults with ADHD, Predominantly Hyperactive Presentation may talk excessively, exhibit restlessness, have difficulty waiting in line, and frequently interrupt others. In contrast, those with ADHD, Predominantly Inattentive Presentation might have difficulty sustaining attention on tasks or activities, struggle with organization, and often lose needed materials. Adults with ADHD, Combined Presentation show both inattentive and hyperactive-impulsive symptoms.

Adults with ADHD show a persistent pattern of inattention and/or hyperactivity and impulsivity that is present in multiple settings. These behaviors result in disruption in social, occupational, and/or family settings and impair one’s functioning in these areas of life. Although historically considered a condition of childhood, ADHD is now recognized as a chronic condition, with many individuals with ADHD in childhood continuing to show symptoms into adulthood.
