Article Synopsis
  • Psycho-behavioral studies indicate that sympathetic skin responses (SSR) correlate with emotional reactions, particularly in patients with Social Anxiety Disorder (SAD), who show heightened SSR linked to empathy and alexithymia.
  • The study involved SAD patients and a control group, utilizing various scales and tests to measure social anxiety, depression, emotional understanding, and SSR in response to visual emotional stimuli.
  • Results revealed that SAD patients exhibited more SSR to negative stimuli and had higher rates of alexithymic traits, suggesting that these factors could amplify their sympathetic sensitivity, necessitating further research for effective treatment approaches.

Objective: Patients with obsessive compulsive disorder (OCD) have inferior social functioning compared to healthy controls, but the exact nature of these social deficits, and the underpinning mechanisms, are unknown. We sought to investigate social functioning in patients with OCD by measuring their involuntary/spontaneous processing of social cues using a specifically designed test, which might reveal deficits in these patients that explicit voluntary tasks do not detect.

Methods: The sample of the study consisted of an OCD group (n = 25) and a control group (n = 26).

The objective of the present study was to compare brain activation in patients with obsessive-compulsive disorder (OCD) who received pharmacotherapy (selective serotonin reuptake inhibitor (SSRI) or a SSRI-risperidone combination) with that in healthy controls using (99m)Tc-hexamethyl propyleneamine oxime (HMPAO) brain single photon emission tomography (SPECT). Twelve OCD patients achieving clinical response (seven SSRI responders, five patients responded to SSRI plus risperidone) underwent post-treatment SPECT scan. The baseline regional cerebral blood flow (rCBF) was significantly reduced in a large part of the cerebral cortex and the left cingulate gyrus in OCD patients compared with controls.
