Alcohol-induced mood transtorno is characterised by mood symptoms (e.g., depressed or elevated mood, decreased engagement in pleasurable activities, increased or decreased energy levels) that develop during or soon after intoxicação com or abstinência from alcohol. The intensity or duration of the symptoms is substantially in excess of mood disturbances that are characteristic of Alcohol intoxicação or Alcohol abstinência. The amount and duration of alcohol uso must be capable of producing mood symptoms. The symptoms are not better explained by a primary mental transtorno (e.g., a Depressive transtorno, a Bipolar transtorno, Transtorno esquizoafetivo), as might be the case if the mood symptoms preceded the onset of the alcohol uso, if the symptoms persist for a substantial period of time after cessation of the alcohol uso or abstinência, or if there is other evidence of a pre-existing primary mental transtorno com mood symptoms (e.g., a history of prior episodes not associated com alcohol uso).
