- <i>Background and Purpose:</i> Pharmacotherapy aimed at stroke rehabilitation through direct central nervous effects may be assumed to work in a similar way for language recovery and sensory-motor recovery. Some data suggest that antidepressant drugs could be beneficial also for functional improvement. This prompted us to investigate whether regression from aphasia after acute stroke could be enhanced by antidepressive drug therapy. <i>Methods:</i> We randomised 90 acute stroke patients with aphasia to either 600 mg moclobemide or placebo daily for 6 months, within 3 weeks of the onset of stroke. Aphasia was assessed prior to treatment and at 6 months, using Reinvang’s ‘Grunntest for afasi’ and the Amsterdam-Nijmegen-Everyday-Language-Test (ANELT). <i>Result:</i> The degree of aphasia decreased significantly at 6 months, with no difference between the moclobemide- and the placebo-treated groups. Multivariate regression analysis including treatment group, activities of daily living, aetiology of stroke, ANELT, and Reinvang’s coefficient at baseline, and neurological deficit confirmed these results. In all, 13 in the moclobemide and 10 in the placebo group stopped taking the study medication. No further change was found in the 56 aphasic patients followed up for another 6 months with no medication. <i>Conclusions:</i> Compared to placebo, treatment with moclobemide for 6 months did not enhance the regression of aphasia following an acute stroke.

- In humans, the volatile C19-steroids androsta-4,16-dien-3-one (AND) and estra-1,3,5(10),16-tetraen-3-ol (EST) have been shown to modulate autonomic nervous system responses, and to cause hypothalamic activation in a gender-specific manner. Using two conditioning paradigms, the authors here show that pigtail macaques and squirrel monkeys of both sexes were able to detect AND and EST at concentrations in the micromolar and mM range, respectively. Male and female spider monkeys, in contrast, differed markedly in their sensitivity to these two odorous steroids, with males not showing any behavioral responses to the highest concentrations of AND tested and females not responding to the highest concentrations of EST. These data provide the first examples of sex-specific bimodal distributions of olfactory sensitivity in a nonhuman primate species.
