Abstract:
 
Sexual dysfunction is not only a common symptom in major depression but also a frequent side-effect of antidepressant medication, mainly of the selective serotonin reuptake-inhibitors (SSRI) that are often prescribed as a first line treatment option. Despite of the increasing incidence and prescription rates, neuronal mechanisms underlying SSRI-related sexual dysfunction are poorly understood and investigations on this topic are scarce. Neuroimaging techniques, mainly functional magnetic resonance imaging (fMRI), provide a feasible approach to investigate these mechanisms since SSRI-related sexual dysfunction is most likely related to central nervous processes. This review summarizes the recent literature regarding the basic clinical findings and imaging correlates of antidepressant-related sexual dysfunction linking brain regions and networks potentially involved two phases and subcomponents of sexual processing and antidepressant action. In particular, fMRI studies on SSRI antidepressants including paroxetine and SNRIs including bupropion are highlighted.

Conclusion:
 
Recent investigations focusing on antidepressant-related sexual dysfunction could demonstrate that neural networks and subcomponents of sexual processing are affected specifically according to the drugs' impact on neurotransmission. Whereas serotonergic drugs like SSRIs led to decreased activation in reward and emotional networks, dopaminergic medications led to enhanced activations within these brain regions, thus, providing evidence and neural correlates for the clinical observation of SSRI-related sexual dysfunction that is absent under dopaminergic drugs. Although further research is necessary, neuroimaging studies thus could link clinically observed antidepressant-related sexual dysfunction to a plausible explanatory neurobiological model. Moreover, it seems reasonable that these approaches may not only be helpful for the selection of specific drugs according to their receptor profiles but also for developing new medications.[/size]

put in Journals format
3 months on 10mg Citalopram (Aug thru Oct '12)

Quit CT after 100mg 2-day binge violently ill w/brain zaps

Nov '12 nasty WD including PSSD so I reinstated at 10mg

2 month taper from Dec '12 thru Jan '13

Feb '13 2nd WD even worse w/every possible SE at once

Coping w/PSSD and Anhedonia ever since

zenzeno, thanks for finding this.

It's unlikely neuroimaging will show anything intelligible about complex hormonal processes, particularly if psychiatry is doing the driving.

 

This study is yet another "this technology is promising" study. It didn't find anything.
