Note: The symptoms are not solely a manifestation of oppositional behavior, defi- ance, hostility, or a failure to understand tasks or instructions. For older adolescents and adults (age 17 and older), at least five symptoms are required.
a. Often fidgets with or taps hands or feet or squirms in seat.
b. Often leaves seat in situations when remaining seated is expected (e.g., leaves his or her place in the classroom, in the office or other workplace, or in other situations that require remaining in place).
0. Often runs about or climbs in situations where it is inappropriate. (Note: In ad- olescents or adults, may be limited to feeling restless.) d. Often unable to play or engage in leisure activities quietly.
6. Is often “on the go," acting as if “driven by a motor” (e.g., is unable to be or un- comfortable being still for extended time, as in restaurants, meetings; may be experienced by others as being restless or difficult to keep up with).
f. Often talks excessively.
g. Often blurts out an answer before a question has been completed (e.g., com- pletes people’s sentences; cannot wait for turn in conversation).
h. Often has difficulty waiting his or her turn (e.g., while waiting in line).
i. Often interrupts or intrudes on others (e.g., butts into conversations. games, or mission; for adolescents and adults, may intrude into or take over what others are doing).
. Several inattentive or hyperactive-impulsive symptoms were present prior to age 12 years.
. Several inattentive or hyperactive-impulsive symptoms are present in two or more set- tings (e.g., at home, school, or work; with friends or relatives; in other activities).
. There is clear evidence that the symptoms interfere with, or reduce the quality of, so- cial, academic, or occupational functioning.
. The symptoms do not occur exclusively during the course of schizophrenia or another psychotic disorder and are not better explained by another mental disorder (e.g., mood disorder, anxiety disorder, dissociative disorder, personality disorder, substance intox- ication or withdrawal).
Specify whether: 314.01 (F90.2) Combined presentation: If both Criterion A1 (inattention) and Crite- rion A2 (hyperactivity-impulsivity) are met for the past 6 months.
314.00 (F90.0) Predominantly inattentive presentation: If Criterion A1 (inattention) is met but Criterion A2 (hyperactivity-impulsivity) is not met for the past 6 months.
314.01 (F90.1) Predominantly hyperactivefimpulsive presentation: If Criterion A2 (hy- peractivity-impulsivity) is met and Criterion A1 (inattention) is not met for the past 6 months.
Specify if: in partial remission: When full criteria were previously met, fewer than the full criteria have been met for the past 6 months, and the symptoms still result in impairment in social, academic, or occupational functioning.
Specify current severity:
Mild: Few, it any, symptoms in excess of those required to make the diagnosis are present, and symptoms result in no more than minor impairments in social or occupa- tional functioning.
Moderate: Symptoms or functional impairment between “mild" and “severe" are present.
Severe: Many symptoms in excess of those required to make the diagnosis, or several symptoms that are particularly severe, are present, or the symptoms result in marked impairment ih social or occupational functioning.
