OBJECTIVES To evaluate the effect of deep brain stimulation of the subthalamic nucleus (STN-DBS) on alexithymia, a deficit in affective regulation, comparing patients with Parkinson's disease (PD) submitted to STN-DBS (DBS group) to PD patients not yet treated with STN-DBS (pre-DBS group) and to healthy participants (C group). METHODS We recruited 27 consecutive STN-DBS PD patients, 38 consec...

In the present study, we investigated whether inter-individual differences in vagally mediated heart rate variability (vmHRV) would be associated with inter-individual differences in empathy and alexithymia. To this end, we determined resting state HF-HRV in 90 individuals that also completed questionnaires assessing inter-individual differences in empathy and alexithymia. Our categorical and d...

BACKGROUND To investigate the possibility if alexithymia could be used as a predictor of attempted suicide among patients suffering from post-traumatic stress disorder. SUBJECTS AND METHODS The study was based on 127 veterans from the 1991-1995 war in Croatia. All the patients involved in this study were previously diagnosed with PTSD. The questionnaires (socio-demographic questionnaire, Miss...

Being exposed to fear signals makes us feel threatened and prompts us to prepare an adaptive response. In our previous studies, we suggested that amygdala (AMG) and premotor cortex (PM) play a role in the preparation of the observers' motor response required by the situation. The present experiment aimed at assessing how interindividual differences in alexithymia--a personality trait associated...

Alexithymia refers to difficulty in identifying and expressing one's emotions, and it is related to disturbed emotional regulation. It was originally proposed as a personality trait that plays a central role in psychosomatic diseases. This review of neuroimaging studies on alexithymia suggests that alexithymia is associated with reduced neural responses to emotional stimuli from the external en...

AIM Alexithymia is associated with limited cognitive processing of emotions by an individual suffering from recurrent urticaria and alexithymia and makes them focus on somatic manifestations of emotional arousal and on poorly controlled compulsive reactions to negative stimulation. Alexithymia is considered to be a personality trait, which, along with other factors, predisposes individuals towa...

Previous research on trichotillomania (TTM) has demonstrated an emotion regulation function of hair pulling behavior. One condition that can impede the regulation of emotions is alexithymia. The present study aimed to explore the relationship between the degree of alexithymia and the severity of hair pulling behavior in individuals with TTM. Multiple strategies were used to recruit a sample of ...

According to the social motivation hypothesis of autism, individuals with high levels of autistic traits experience reduced levels of reward from social interactions. However, empirical evidence to date has been mixed, with some studies reporting lower levels of social reward in individuals with Autism Spectrum Disorder (ASD), and others finding no difference when compared to typically developi...

Both Emotional Cascade Theory and Linehan's Biosocial Theory suggest dysregulated behaviors associated with Borderline Personality Disorder (BPD) emerge, in part, because of cycles of rumination, poor emotional recognition and poor emotion regulation. In this study we examined relationships between rumination, alexithymia, and emotion regulation in predicting dysregulated behaviors associated w...

Considering that impaired coping with stress is closely linked with emergence of stress-sensitive disorders most notably in alexithymic individuals, we conducted the first study examining stress-related autonomic reactivity in alexithymic pain disorder patients. Twenty-one pain disorder patients with high and an equivalent patient group with low alexithymia scores were exposed to three types of...
