Stimulant-induced delirium including amphetamines, methamphetamine or methcathinone
Delirium induzido por estimulantes, incluindo anfetaminas, metanfetamina ou metcatinona
CategoryDefinition
Stimulant-induced delirium including amphetamines, methamphetamine and methcathinone is characterised by an acute state of disturbed attention and awareness with specific features of delirium that develops during or soon after substance intoxication or withdrawal or during the use of stimulants. The amount and duration of stimulant use must be capable of producing delirium. The symptoms are not better explained by a primary mental disorder, by use of or withdrawal from a different substance, or by another health condition that is not classified under Mental, behavioural and neurodevelopmental disorders.
Diagnostic Criteria
Essential (Required) Features:
- All diagnostic requirements for 6D70 Delirium are met.
- There is evidence from history, physical examination, or laboratory findings that the neurocognitive disturbance is caused by the direct physiological consequences of stimulant use. This judgment depends on establishing that the course of the Delirium (e.g., onset, trajectory of symptoms, eventual remission with elimination of the substance from the body) is consistent with causation by stimulant use.
- The duration or severity of the symptoms is substantially in excess of the characteristic syndrome of Stimulant Intoxication or Stimulant Withdrawal.
- The diagnostic requirements for 6D70.2 Delirium Due to Multiple Etiological Factors are not met.
Note: See 6D70 Delirium for other CDDR sections, including Additional Clinical Features, Boundary with Normality (Threshold), Course Features, Developmental Presentations, Culture-Related Features, and Boundaries with Other Disorders and Conditions (Differential Diagnosis).
