Table 1.
Neuropsychological test results at baseline and one-year follow-up. Summary of raw scores and corresponding Z-scores (or percentile ranks) for key cognitive domains, demonstrating progression of memory, executive, language, and visuospatial impairments over one year. N/A indicates that the test was not administered at follow-up because the patient was too cognitively impaired to complete it. Word list recognition Z-score at follow‐up could not be calculated due to false positives. Abbreviations: WMS-R = Wechsler Memory Scale-Revised
