ICD-11 Criteria for Attention Deficit Hyperactivity Disorder (ADHD) 6A05
Attention deficit hyperactivity
disorder is characterised by a persistent pattern (at least 6 months) of
inattention and/or hyperactivity-impulsivity that has a direct negative impact
on academic, occupational, or social functioning. There is evidence of significant
inattention and/or hyperactivity-impulsivity symptoms prior to age 12,
typically by early to mid-childhood, though some individuals may first come to
clinical attention later. The degree of inattention and
hyperactivity-impulsivity is outside the limits of normal variation expected
for age and level of intellectual functioning. Inattention refers to
significant difficulty in sustaining attention to tasks that do not provide a
high level of stimulation or frequent rewards, distractibility and problems
with organisation. Hyperactivity refers to excessive motor activity and
difficulties with remaining still, most evident in structured situations that
require behavioural self-control. Impulsivity is a tendency to act in response
to immediate stimuli, without deliberation or consideration of the risks and
consequences. The relative balance and the specific manifestations of
inattentive and hyperactive-impulsive characteristics varies across individuals
and may change over the course of development. In order for a diagnosis to be
made, manifestations of inattention and/or hyperactivity-impulsivity must be
evident across multiple situations or settings (e.g., home, school, work, with
friends or relatives), but are likely to vary according to the structure and
demands of the setting. Symptoms are not better accounted for by another
mental, behavioural, or neurodevelopmental disorder and are not due to the
effect of a substance or medication.

6A05.0 Attention deficit hyperactivity disorder, predominantly inattentive presentation
All definitional requirements for
attention deficit hyperactivity disorder are met and inattentive symptoms are
predominant in the clinical presentation. Inattention refers to significant
difficulty in sustaining attention to tasks that do not provide a high level of
stimulation or frequent rewards, distractibility and problems with
organisation. Some hyperactive-impulsive symptoms may also be present, but
these are not clinically significant in relation to the inattentive symptoms.
6A05.1 Attention deficit hyperactivity disorder, predominantly hyperactive-impulsive presentation
All definitional requirements for
attention deficit hyperactivity disorder are met and hyperactive-impulsive
symptoms are predominant in the clinical presentation. Hyperactivity refers to
excessive motor activity and difficulties with remaining still, most evident in
structured situations that require behavioural self-control. Impulsivity is a
tendency to act in response to immediate stimuli, without deliberation or
consideration of the risks and consequences. Some inattentive symptoms may also
be present, but these are not clinically significant in relation to the
hyperactive-impulsive symptoms.
6A05.2 Attention deficit hyperactivity disorder, combined presentation
All definitional requirements for
attention deficit hyperactivity disorder are met. Both inattentive and
hyperactive-impulsive symptoms are clinically significant, with neither
predominating in the clinical presentation. Inattention refers to significant
difficulty in sustaining attention to tasks that do not provide a high level of
stimulation or frequent rewards, distractibility and problems with organisation.
Hyperactivity refers to excessive motor activity and difficulties with
remaining still, most evident in structured situations that require behavioural
self-control. Impulsivity is a tendency to act in response to immediate
stimuli, without deliberation or consideration of the risks and consequences.
6A05.Y Attention deficit hyperactivity disorder, other specified presentation
6A05.Z Attention
deficit hyperactivity disorder, presentation unspecified
