Alterations in voxel based morphometry and resting state functional connectivity in men with compulsive sexual behavior disorder in the Sex@Brain study.
Aim: Compulsive Sexual Behavior Disorder (CSBD) is a new category in ICD-11. Research examining underlying brain mechanisms is sparse. Research into neurobiological differences can be helpful in advancing the possibilities of new diagnostic approaches and therapeutic methods. The present study aimed to examine brain matter volume and resting state functional connectivity (rs-FC) in CSBD.
Methods: Structural and rs-FC magnetic resonance imaging and data from questionnaires were collected in 30 men with CSBD and 32 age- and education-matched controls. Whole brain voxel based morphometry (VBM) and seed based rs-FC in a-priori defined seeds were analyzed.
Results: Structural analyses showed that men with CSBD had significantly increased gray matter volume in the right cerebellum, middle occipital and superior frontal lobe. No differences in rs-FC could be detected when using these brain structures as seed regions in rs-FC. In contrast, literature based rs-FC analysis revealed decreased rs-FC between the right orbital middle frontal cortex (mOFC) and the right gyrus rectus, as well as between left pallidum and right post/precentral gyrus in men with CSBD. In the left amygdala we observed increased rs-FC with precuneus in this group. In addition, most of these measures correlated with symptom severity.
Conclusion: Structural findings may underscore the idea that the cerebellum plays an important role in sexual arousal and CSBD. Perhaps, a simultaneous activation of the left amygdala and the precuneus reflects a constant sexual occupation of men with CSBD. Furthermore, lower connectivity between mOFC and gyrus rectus in CSBD may support the assumption that sexual stimuli are evaluated more positively because inhibition is decreased.
期刊介绍:
The aim of Journal of Behavioral Addictions is to create a forum for the scientific information exchange with regard to behavioral addictions. The journal is a broad focused interdisciplinary one that publishes manuscripts on different approaches of non-substance addictions, research reports focusing on the addictive patterns of various behaviors, especially disorders of the impulsive-compulsive spectrum, and also publishes reviews in these topics. Coverage ranges from genetic and neurobiological research through psychological and clinical psychiatric approaches to epidemiological, sociological and anthropological aspects.
