“…Consistent with the findings from somatoform pain disorder patients (Stoeter et al, 2007), the present study showed that increased FCS was in the right ITG in the patient group compared to the control group. More specifically, neuroimaging data support the linking of the temporal lobe to alexithymia (Aust et al, 2014;Deng et al, 2013). Alexithymia is defined as difficulty in describing subjective feelings, and distinguishing between feelings and bodily sensations of emotional arousal.…”

Background: Evidence of brain structural and functional alterations have been implicated in patients with somatization disorder (SD). However, little is known about brain functional connectivity in SD. In the present study, resting-state functional magnetic resonance imaging (fMRI) and graph theory were used to obtain a comprehensive view of wholebrain functional connectivity and to investigate the changes of voxel-wise functional networks in patients with SD.Methods: Twenty-five first-episode, medication-naive patients with SD and 28 age-, sex-and education-matched healthy controls (HCs) underwent resting-state fMRI. The graph theory approach was employed to analyze the data.Results: Compared to the HCs, patients with SD showed significantly increased functional connectivity strength in the right inferior temporal gyrus (ITG). There is a significant positive correlation between the z-values of the cluster in the right ITG and Hamilton Anxiety Scale scores. Conclusions:Our findings indicate that there is a disruption of the functional connectivity pattern in the right ITG in first-episode, treatment-naive patients with SD, which bears clinical significance.

“…It is related to emotion dysregulation (Stasiewicz et al, 2012) and health-related quality of life (von Rimscha et al, 2013). It occurs in up to 50% of psychiatric patients, such as those suffering from depression or somatoform pain (Fukunishi et al, 1992;Burba et al, 2006), and in about 8% of the general population (Honkalampi et al, 2009;Karukivi et al, 2010;Deng et al, 2013). Twin studies established that a large portion of individual differences in alexithymia can be attributed to genetic factors, with heritability of 30-42% (Honkalampi et al, 2009;Karukivi et al, 2010;Deng et al, 2013).…”

A study associating the serotonin transporter promoter region (5-HTTLPR) in serotonin transporter gene (5-HTT) with alexithymia (Kano et al, 2012) demonstrated that, compared with individuals carrying the SS/LS genotype, individuals with the LL genotype registered higher scores on Toronto Alexithymia Scale (TAS-20) which is a commonly used self-report instrument assessing alexithymic characteristics (Bagby et al, 1994).…”

“…Neuroimaging studies have shown that alexithymia is related to structural differences in emotional systems of the brain (Borsci et al, 2009;Laricchiuta et al, 2014), as well as to altered patterns of regional brain activity during the processing of emotional stimuli (Deng, Ma, & Tang, 2013;Duan, Dai, Gong, & Chen, 2010;Heinzel et al, 2010), mentalizing (Moriguchi et al, 2006), and imagery (Mantani, Okamoto, Shirao, Okada, & Yamawaki, 2005). There is evidence for a genetic contribution alexithymia (Theorell, Lennartsson, Mosing, & Ullen, 2014), as well as for environmental causes.…”

Alexithymia is characterized by deficits in the ability to identify, differentiate, and describe emotions-abilities that are of importance for social interactions, well-being, and, consequently, also for health. The aim of this study was to investigate whether achievements in cultural activities are associated with alexithymia. Participants from the Swedish Twin Registry were 2,279 men and 3,152 women in the ages 27 to 54. Cultural achievement was measured with the Creative Achievement Questionnaire (CAQ) in which participants estimate their achievement in the domains writing, music, visual arts, theater, and dance on a 7-point scale. Alexithymia was measured with the Toronto Alexithymia Score (TAS 20). In sex separated, age, and educationadjusted multivariate analyses, nonpractitioners, amateurs, and professionals in the 5 different CAQ domains were compared with regard to alexithymia scores. For both men and women, achievement in writing and music contributed statistically and independently of one another to a low alexithymia score. In addition, achievement in visual arts contributed independently to low alexithymia score in men and achievement in theatre to low alexithymia score in women. Total creative achievement was calculated as a sum score across domains, and the distribution divided into tertile groups. These groups were compared with regard to alexithymia scores. Large tertile differences were found in both sexes. The results show differences between modalities and cumulative effects of multiple creative achievements.
