“…While Puccinini et al 9 previously reported an association of older age and aberrant motor behaviors, we observed the opposite effect in the univariate and multivariable logistic regression analyses of the MCI and pooled samples. We were also unable to confirm the association between older age and psychosis reported by two previous studies 8, 9 and found the opposite association across all three samples in the univariate but not the multivariable analyses.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…In contrast to past studies (Hirono et al, 1998;Harwood et al, 1999;Bassiony et al, 2000), age, APOE e4 status, AD diagnosis, and poorer health did not predict delusions. Increased dementia severity predicted hallucinations but decreased the odds of depression; the former finding is consistent with that of Bassiony et al (2000), and the latter is consistent with Lyketsos et al (2000) and Aalten et al (2005). AD decreased the odds of agitation, disinhibition, and depression; the latter is (Payne et al, 1998;Groves et al, 2000).…”

“…This result is in keeping with most previous studies [5][6][7]. We also found an increase of psychosis with increasing age, which has been already reported [5,7,10].…”
