Delirium induzido por outra substância psicoativa especificada, incluindo medicamentos
CategoryDefinition
Delirium induced by other specified psychoactive substance 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 a specified psychoactive substance. The amount and duration of use of the specified substance 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 the use of the other specified substance or medication. This judgment depends on establishing that:
- The specified substance and the amount and duration of its use or withdrawal from the specified substance 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 substance.
- 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 substance.
- The diagnostic requirements for 6D70.2 Delirium Due to Multiple Etiological Factors are not met.
