Delirium induced by multiple specified psychoactive substances including medications
Delirium induzido por múltiplas substâncias psicoativas especificadas, incluindo medicamentos
CategoryDefinition
Delirium induced by multiple specified psychoactive substances 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 multiple specified substances. The amount and duration of use of the multiple specified substances must be capable of producing delirium. The symptoms are not better explained by a primary mental disorder, by use of or withdrawal from a substance other than those specified, or by another health condition that is not classified under Mental, behavioural and neurodevelopmental disorders. Note that this diagnosis applies only to those situations in which delirium is present but it cannot be determined which of multiple psychoactive substances is the cause of the delirium. In cases of multiple psychoactive substance use in which more than one specific substance can be identified as a cause of the delirium, the corresponding specific substance-induced delirium diagnoses should be given instead.
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 the use of multiple specified substances. This judgment depends on establishing that:
- The specified substances and the amount and duration of their use or withdrawal from the specified substances is known to be capable of producing Delirium; and
- 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 the use of the specified substances.
- The duration or severity of the symptoms is substantially in excess of the characteristic syndrome of Substance Intoxication or Substance Withdrawal due to the specified substances.
- The diagnostic requirements for 6D70.2 Delirium Due to Multiple Etiological Factors are not met.
