Analysis suppression

Analysis suppression is a distinct decrease in a person's overall ability to process information [1] [2] [3] and logically or creatively analyze concepts, ideas, and scenarios. [4] The experience of this effect leads to significant difficulty in contemplating or understanding basic ideas in a manner which can temporarily prevent normal cognitive functioning.

Analysis suppression is often accompanied by other coinciding effects such as sedation, thought deceleration, and emotion suppression. It is most commonly induced under the influence of heavy dosages of antipsychotic compounds [1] [2] [4] , and is associated with long term use of such drugs [5] like quetiapine, haloperidol, and risperidone. However, it can also occur in a less consistent form under the influence of heavy dosages of dissociatives, cannabinoids [3] , and GABAergic depressants [6] .
