Which type of ADHD is characterized primarily by lack of attention?

The type of ADHD characterized primarily by a lack of attention is known as the Predominately Inattentive Type. Individuals with this type often struggle with maintaining focus, following through on tasks, and organizing activities. They may frequently become easily distracted and have difficulty sustaining attention in conversations or on work tasks. This can manifest in children as an apparent daydreaming or seeming to not listen when spoken to directly, as well as missing details and making careless mistakes.

In contrast, other types of ADHD address different symptoms. The Combined Type includes both inattentive and hyperactive-impulsive symptoms, while the Predominately Hyperactive-Impulsive Type focuses primarily on hyperactivity and impulsivity without the significant inattentive symptoms. The term "Compulsive Type" does not align with established ADHD classifications, as it is not recognized in the diagnostic criteria for ADHD.
