Correlation of Factor Scores in Processing Speed and Verbal Memory with 18F-ASEM VT in Hippocampus of Patients with Recent-Onset Psychosis*
| Neuropsychological domain | Partial correlation coefficient (r) |
| Processing speed | 0.73† |
| Attention and working memory | 0.62 |
| Verbal memory | 0.75† |
| Visual memory | 0.63 |
| Ideational fluency | 0.67 |
| Executive functioning | 0.53 |
↵* After controlling for effect of age. Of 11 patients who underwent 18F-ASEM PET, 10 patients (5 with NP and 5 with AP) completed the neuropsychological battery because it was added after the first patient participant. Factor scores were generated as averages of standardized scores from tests within each of 6 cognitive domains. Hippocampal 18F-ASEM VT values were estimated using data from images that were corrected for partial-volume effects.
