Conceived and designed the experiments: The catecholamine hypothesis of affective disorders: Amarin developed Miraxion to treat Huntington's disease, and expects to start late-stage trials of the drug for that use this year. Judith Warner thought she would find pushy parents and irresponsible doctors behind children on drugs like Ritalin and Prozac.
Interaction of the enantiomers of fluoxetine and norfluoxetine with human liver cytochromes P The literature also implicates distinct anatomical changes in radial glia-like progenitors in this part of the hippocampus  and these regional specific effects could explain part of the discrepancies in literature on FLX effects on neurogenesis.
N-substituted cyclopropylamines as monoamine oxidase inhibitors. Last week, a federal advisory panel urged regulators to warn parents that antidepressant drugs not only increase the risk of suicide in some children, but that most have a poor track record in curing their disease.
Abstract The antidepressant drug fluoxetine Prozac has been increasingly prescribed to children and adolescents with depressive disorders despite a lack of thorough understanding of its therapeutic effects in the paediatric population and of its putative neurodevelopmental effects. Upon chronic SSRI treatment, 5-HT receptor desensitisation is believed to be instrumental in alleviating depressive symptoms . Within the dorsal and ventral hippocampus, the infra- and suprapyramidal blades of the DG further differ in many anatomical, morphological and molecular aspects, with the suprapyramidal blade e.
The effects of chronic FLX on TPH immunoreactivity are indicative of a clear age-at-treatment dependence, with post-hoc tests showing higher TPH expression in adolescent-treated animals and a reduced expression in adult-treated rats. Click through the PLOS taxonomy to find articles in your field. Since little is still known, however, on the effects of chronic SSRI exposure on TPH expression and on neurogenesis markers during adolescence, we here set out to determine whether chronic FLX treatment induces age-dependent and regional-specific effects on proliferation, adult neurogenesis and TPH expression, and notably, whether interaction effects exist.
Immunohistochemistry To study changes in proliferation in the adult brain, Ki immunohistochemistry was used. Accept and close More info. Given the evidence for the functional dissociations between the supra- and infrapyramidal blades and the rostral and caudal subregions of the hippocampus, the location in which adult-generated neurons reside becomes highly relevant. Diazepam Valium is among the most successful drugs from the onset of the psychopharmacological revolution that began during the s.
All experiments were carried out according to the guidelines set forth by Dutch regulations on animal welfare and protection. In the early s, evidence of the role of serotonin 5-hydroxytryptamine or 5-HT in depression began to emerge and the hypothesis that enhancing 5-HT neurotransmission would be a viable mechanism to mediate antidepressant response was put forward.

If this is true, it means the drug should remain continuously present in order to propagate its positive effect on neurogenesis at this age. Serotonin or tenure for the pharmacologist. The underrecognition and undertreatment of depression:
