Stimulant-induced mood transtorno including amphetamines, methamphetamine and methcathinone 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 or abstinência due to stimulants. The intensity or duration of the symptoms is substantially in excess of mood disturbances that are characteristic of Stimulant intoxicação or Stimulant abstinência. The amount and duration of stimulant 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 stimulant uso, if the symptoms persist for a substantial period of time after cessation of the stimulant 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 uso of stimulants).
