Abstract:
This study evaluated neurocognitive functioning in 26 youth with Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS) and primarily obsessive-compulsive disorder (OCD) symptoms. Marked impairment in visuospatial recall memory (as assessed using the Rey-Osterrieth Complex Figure Test) was observed in spite of average to above-average performance on academic and other neurocognitive measures. Group A beta-hemolytic Streptococcus titer elevations were associated with worse performance on tasks of neurocognitive and executive ability (Stroop Color-Word Interference Test), visuospatial memory, and fine motor speed (finger tapping) as well as elevated obsessive-compulsive symptom severity.
