Cognitive domains assessed included immediate and delayed episodic memory (Wechsler Memory Scale-Third edition; Logical Memory; Visual Reproduction; Rey Auditory Verbal Learning Test), processing speed (Trail Making Test A), executive functioning (Trail Making Test B; Delis-Kaplan Executive Functioning Scale \u2013 Sorting), and visuospatial ability (Rey-Osterrieth Complex Figure copy).<\/jats:p><\/jats:sec><jats:sec id=\"S1355617721000692_as3\"><jats:title><jats:bold>Results:<\/jats:bold><\/jats:title><jats:p>The PPAOS patients were cognitively average or higher in the domains of immediate and delayed episodic memory, processing speed, executive functioning, and visuospatial ability. Patients with AOS-PAA performed more poorly on tests of immediate and delayed episodic memory and executive functioning compared to those with PPAOS. For every 1 unit increase in aphasia severity (e.g. mild to moderate), performance declined by 1\/3 to 1\/2 a standard deviation depending on cognitive domain. The degree of decline was stronger within the more verbally mediated domains, but was also notable in less verbally mediated domains.<\/jats:p><\/jats:sec><jats:sec id=\"S1355617721000692_as4\"><jats:title><jats:bold>Conclusion:<\/jats:bold><\/jats:title><jats:p>The study provides neuropsychological evidence further supporting the distinction of PPAOS from primary progressive aphasia and should be used to inform future diagnostic criteria.
