Cognitive symptoms in primary psychotic transtornos refer to cognitive impairment in any of the following domains: speed of processing, attention/concentration, orientation, judgment, abstraction, verbal or visual learning, and working memory. The cognitive impairment is not attributable to a neurodevelopmental transtorno, a Delirium or other neurocognitive transtorno, or the direct effects of a substance or medication on the central nervous system, including abstinência effects. Ideally, uso of this category should be based on the results of locally validated, standardized neuropsychological assessments, although such measures may not be available in all settings. The rating should be made based on the severity of cognitive symptoms during the past week.
