“…In the cohort of 200 patients with bipolar affective disorder the mean age of onset was approximately 30 years, which is consistent with other reports in the literature (Winokur et al 1969;Petterson, 1977;Loranger & Levine, 1978). The mean age of onset, however, can be a misleading statistic which obscures the wide range and skewed distribution of the age of onset.…”

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.

“…Clinical data are shown in Table 1, which includes information about both the first (derivation) and second (cross-validation) groups. The diagnostic groups differed in age, in a manner consistent with published data for age of onset of endogenous (ED) (Angst et al 1973;Loranger and Levine 1978) and nonendogenous (Spicer et al 1973) depression (ND).…”

“…The diag nostic groups differed in mean age, though not in age range. The difference in mean age was consistent with published data for median age of onset of unipolar and bipolar affective disorder (Angst et a!, 1973;Loranger and Levine, 1978), and with data for non endogenous depression (Spicer eta!, 1973).…”
