ADHD-PI

Also written as: ADHD-PI — Attention-Deficit/Hyperactivity Disorder Predominantly Inattentive

Attention-deficit/hyperactivity disorder predominantly inattentive presentation, characterized primarily by attention difficulties without hyperactivity.

Full Definition

ADHD-PI represents one of three presentations of attention-deficit/hyperactivity disorder, where the individual meets criteria for inattention but not hyperactivity-impulsivity. Children with this presentation often appear dreamy, forgetful, and disorganized, frequently losing things and having difficulty sustaining attention to tasks or activities. They may be overlooked in classroom settings because they don't exhibit disruptive behaviors typical of the combined or hyperactive-impulsive presentations. This presentation was formerly known as ADD (attention deficit disorder) without hyperactivity. Diagnosis requires six or more symptoms of inattention persisting for at least six months.

Usage

Usage note: Use current DSM-5-TR terminology; avoid outdated 'ADD' designation.
