Neurobiological Underpinnings to Hypersexual Disorder

"* Structural MRI (T1 weighted)~* Diffusion Tensor Imaging (DTI)~* resting state functional MRI (rs-fMRI)~* functional MRI (fMRI): Brain activity will be measured in response to sexual images (visually evoked sexual arousal; processing of sexual stimuli), and importantly during a phase when these stimuli are anticipated (neural correlates of wanting and desire; reward anticipation)."

"We will administer neuropsychological tests assessing objective measures for~* intelligence (Ravens Matrices)~* impulsivity and risk-taking behavior (Balloon Analogue Risk Task)~* inhibitory control (Stop Signal Task)."

Administered questionnaires include anxiety and depression symptoms (MADRS, HADS, GAD), drug use (AUDIT, DUDIT), attention deficits (ASRS), impulsivity (BIS-11), reward seeking behavior (BIS/BAS), sexual orientation, (hyper)sexual behavior, desire and compulsivity aspects (HDSI, HBI, SCS, SDI, SIS/SES).

Blood samples will be taken for routine health assessment, measurement of sex hormonal levels, HPA-axis function test (dexamethasone suppression), and potential DNA extraction and (epi)genetic profiling.
