Serotonin Reuptake Inhibitor Citalopram Inhibits GnRH synthesis and Spermatogenesis in the Male Zebrafish.
Abstract Selective serotonin reuptake inhibitors (SSRIs) are widely used antidepressants for the treatment of depression. However, SSRIs cause sexual side effects such as anorgasmia, erectile dysfunction and diminished libido which are thought to be mediated through the serotonin (5-hydroxytryptamine, 5-HT) system. In vertebrates, gonadotropin-releasing hormone (GnRH) neurons play an important role in the control of reproduction. To elucidate the neuroendocrine mechanisms of SSRI induced reproductive failure, we examined the neuronal association between 5-HT and GnRH (GnRH2 and GnRH3) systems in the male zebrafish...

Dissociable Effects of Serotonin and Dopamine on the Valuation of Harm in Moral Decision Making.
Abstract An aversion to harming others is a core component of human morality and is disturbed in antisocial behavior [1-4]. Deficient harm aversion may underlie instrumental and reactive aggression, which both feature in psychopathy . Past work has highlighted monoaminergic influences on aggression [6-11], but a mechanistic account of how monoamines regulate antisocial motives remains elusive. We previously observed that most people show a greater aversion to inflicting pain on others than themselves . Here, we investigated whether this hyperaltruistic disposition is susceptible to monoaminergic control. We...

Improving response inhibition systems in frontotemporal dementia with citalopram
Disinhibition is a cardinal feature of the behavioural variant of frontotemporal dementia, presenting as impulsive and impetuous behaviours that are often difficult to manage. The options for symptomatic treatments are limited, but a potential target for therapy is the restoration of serotonergic function, which is both deficient in behavioural variant frontotemporal dementia and closely associated with inhibitory control. Based on preclinical studies and psychopharmacological interventions in other disorders, we predicted that inhibition would be associated with the right inferior frontal gyrus and dependent on serotonin....

Role of the serotonin transporter gene locus in the response to SSRI treatment of major depressive disorder in late life
It has been suggested that the serotonin or 5-hydroxytriptamine (5-HT) transporter (5-HTT) and its gene-linked polymorphic region (5-HTTLPR) are selective serotonin reuptake inhibitor (SSRI) response modulators in late-life depression (LLD), and particularly in late-life major depressive disorder (MDD). Previous studies differed in design and results. Our study aimed to investigate the solute carrier family 6 (neurotransmitter transporter and serotonin) member 4 (SLC6A4) gene locus, encoding 5-HTT and SSRI treatment response in late-life MDD.

The effects of gestational stress and SSRI antidepressant treatment on structural plasticity in the postpartum brain - a translational model for postpartum depression.
Abstract Postpartum depression (PPD) is a common complication following childbirth experienced by one in every five new mothers. Although the neural basis of PPD remains unknown previous research in rats has shown that gestational stress, a risk factor for PPD, induces depressive-like behavior during the postpartum period. Moreover, the effect of gestational stress on postpartum mood is accompanied by structural modifications within the nucleus accumbens (NAc) and the medial prefrontal cortex (mPFC) - limbic regions that have been linked to PPD. Mothers diagnosed with PPD are often prescribed selective serotonin r...

Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) for the prevention of tension-type headache in adults.
CONCLUSIONS: Since the last version of this review, the new included studies have not added high quality evidence to support the use of SSRIs or venlafaxine (a SNRI) as preventive drugs for tension-type headache. Over two months of treatment, SSRIs or venlafaxine are no more effective than placebo or amitriptyline in reducing headache frequency in patients with chronic tension-type headache. SSRIs seem to be less effective than tricyclic antidepressants in terms of intake of analgesic medications. Tricyclic antidepressants are associated with more adverse events; however, this did not cause a greater number of withdrawals....

A targeted pharmacotherapy is complicated by the underlying cognitive impairment and physical comorbidities. The current review focusses on recent evidence on the use of antidepressives and antipsychotics for psychotic disturbances, agitation and depression in dementia and analyzes currently published randomized controlled clinical trials and meta-analyses. The evidence on the use of antipsychotics for different indications favors risperidone, with lower evidence lev...

Repeated ketamine administration redeems the time lag for citalopram's antidepressant-like effects
Publication date: Available online 18 March 2015 Source:European Psychiatry Author(s): G.-F. Zhang , W.-X. Liu , L.-L. Qiu , J. Guo , X.-M. Wang , H.-L. Sun , J.-J. Yang , Z.-Q. Zhou Current available antidepressants exhibit low remission rate with a long response lag time. Growing evidence has demonstrated acute sub-anesthetic dose of ketamine exerts rapid, robust, and lasting antidepressant effects. However, a long term use of ketamine tends to elicit its adverse reactions. The present study aimed to investigate the antidepressant-like effects of intermittent and consecutive administrations of ketamine on chronic unpre...

Cloning and Serotonergic Regulation of RING Finger Protein38 (rnf38) in the Brain of Medaka (Oryzias latipes)
Publication date: Available online 12 March 2015 Source:Neuroscience Author(s): Shogo Moriya , Nazmina Bahadur Khel , Ishwar S. Parhar Serotonin (5-HT) is a key regulator of mood and sexual behaviours. 5-HT reuptake inhibitors have been used as antidepressants. RING finger proteins have been associated with 5-HT regulation but their role remains largely unknown. Some RING finger proteins are involved in the serotonergic system, therefore, we speculate that the gene expression of rnf38 might be regulated by the serotonergic system. In the present study, we aimed to identify the full length sequence of medaka (Oryzias lati...

Vitamin C as an adjuvant for treating major depressive disorder and suicidal behavior, a randomized placebo-controlled clinical trial
Conclusion: Adding vitamin C to citalopram did not increase the efficacy of citalopram in MDD patients. Vitamin C plus citalopram is as effective as placebo plus citalopram for treating adult patients with suicidal behavior. No serious adverse effect for this combination was identified during this trial.Trial registrationThis trial was registered at http://www.irct.ir. The registration number of this trial was: IRCT201312263930N31. Date registered: 5 July 2014. (Source: Trials)
