This is the second published case report of Lleuprolide acetate for depot suspension (LD)-induced mania. Both reports detail a patient with a prior psychiatric history of both depressive and hypomanic episodes. While depression is a predictable and documented side effect of LD and menopause (especially in those with a previoushistory of symptoms), manic reactions are rare and unexplained. Possible causative mechanismsbehind the LD-induced manic episodes are discussed, and we suggest that patients with a single previous hypomanic episode are at risk for LD-induced mania.  相似文献

Children differ in how quickly they reach linguistic milestones. Boys typically produce their first multi‐word sentences later than girls do. We ask here whether there are sex differences in children’s gestures that precede, and presage, these sex differences in speech. To explore this question, we observed 22 girls and 18 boys every 4 months as they progressed from one‐word speech to multi‐word speech. We found that boys not only produced speech + speech (S+S) combinations (‘drink juice’) 3 months later than girls, but they also produced gesture + speech (G+S) combinations expressing the same types of semantic relations (‘eat’ + point at cookie) 3 months later than girls. Because G+S combinations are produced earlier than S+S combinations, children’s gestures provide the first sign that boys are likely to lag behind girls in the onset of sentence constructions.  相似文献

Phantom contours are a visual illusion that can define regions with distinctive boundaries when no real surrounding edges exist. Spatial-frequency sensitivity is known to vary reliably across the visual-processing pathways, as does temporal-frequency sensitivity. Given that the effect of temporal frequency on phantom-contour detection has been previously established, and that the relationship between spatial frequency and temporal frequency is known, two experiments were designed to measure the highest level of spatial frequency that would still allow reliable pattern detection at different temporal frequencies by using the phantom-contour paradigm. The results revealed that phantom-contour detection is impaired when the stimulus has a high spatial-frequency content and that phantom-contour perception is supported by low spatial frequencies.  相似文献

Cognitive models of social anxiety disorder (SAD) posit aberrant beliefs about the social self as a key psychological mechanism that maintains fear of negative evaluation in social and performance situations. Consequently, a distorted self-view should be evident when recalling painful autobiographical social memories, as reflected in linguistic expression, negative self-beliefs, and emotion and avoidance. To test this hypothesis, 42 adults diagnosed with SAD and 27 non-psychiatric healthy controls (HC) composed autobiographical narratives of distinct social anxiety related situations, generated negative self-beliefs (NSB), and provided emotion and avoidance ratings. Although narratives were matched for initial emotional intensity and present vividness, linguistic analyses demonstrated that, compared to HC, SAD employed more self-referential, anxiety, and sensory words, and made fewer references to other people. There were no differences in the number of self-referential NSB identified by SAD and HC. Social anxiety symptom severity, however, was associated with greater self-referential NSB in SAD only. SAD reported greater current self-conscious emotions when recalling autobiographical social situations, and greater active avoidance of similar situations than did HC. These findings support cognitive models of SAD, and suggest that autobiographical memory of social situations in SAD may influence current and future thinking, emotion, and behavioral avoidance.  相似文献
