Hovedbudskap
Legemidler er utløsende årsak til ca. en tredel av tilfellene av delirium hos eldre
De aller eldste, personer med degenerative hjernesykdommer eller alvorlig akutt sykdom er mest utsatt
Antikolinerge legemidler, midler som påvirker andre transmittorsystemer, cerebral metabolisme eller midler som gir hyponatremi eller urinretensjon, kan utløse delirium
Legemidler som er kjent for å kunne utløse delirium bør vurderes seponert eller gitt i redusert dose
