RESUMEN

Somatoform disorder patients show a variety of emotional disturbances including impaired emotion recognition and increased empathic distress. In a previous paper, our group showed that several brain regions involved in emotional processing, such as the parahippocampal gyrus and other regions, were less activated in pre-treatment somatoform disorder patients (compared to healthy controls) during an empathy task. Since the parahippocampal gyrus is involved in emotional memory, its decreased activation might reflect the repression of emotional memories (which-according to psychoanalytical concepts-plays an important role in somatoform disorder). Psychodynamic psychotherapy aims at increasing the understanding of emotional conflicts as well as uncovering repressed emotions. We were interested, whether brain activity in the parahippocampal gyrus normalized after (inpatient) multimodal psychodynamic psychotherapy. Using fMRI, subjects were scanned while they shared the emotional states of presented facial stimuli expressing anger, disgust, joy, and a neutral expression; distorted stimuli with unrecognizable content served as control condition. 15 somatoform disorder patients were scanned twice, pre and post multimodal psychodynamic psychotherapy; in addition, 15 age-matched healthy control subjects were investigated. Effects of psychotherapy on hemodynamic responses were analyzed implementing two approaches: (1) an a priori region of interest approach and (2) a voxelwise whole brain analysis. Both analyses revealed increased hemodynamic responses in the left and right parahippocampal gyrus (and other regions) after multimodal psychotherapy in the contrast "empathy with anger"-"control." Our results are in line with psychoanalytical concepts about somatoform disorder. They suggest the parahippocampal gyrus is crucially involved in the neurobiological mechanisms which underly the emotional deficits of somatoform disorder patients.

RESUMEN

Somatoform disorder patients suffer from impaired emotion recognition and other emotional deficits. Emotional empathy refers to the understanding and sharing of emotions of others in social contexts. It is likely that the emotional deficits of somatoform disorder patients are linked to disturbed empathic abilities; however, little is known so far about empathic deficits of somatoform patients and the underlying neural mechanisms. We used fMRI and an empathy paradigm to investigate 20 somatoform disorder patients and 20 healthy controls. The empathy paradigm contained facial pictures expressing anger, joy, disgust, and a neutral emotional state; a control condition contained unrecognizable stimuli. In addition, questionnaires testing for somatization, alexithymia, depression, empathy, and emotion recognition were applied. Behavioral results confirmed impaired emotion recognition in somatoform disorder and indicated a rather distinct pattern of empathic deficits of somatoform patients with specific difficulties in "empathic distress." In addition, somatoform patients revealed brain areas with diminished activity in the contrasts "all emotions"-"control," "anger"-"control," and "joy"-"control," whereas we did not find brain areas with altered activity in the contrasts "disgust"-"control" and "neutral"-"control." Significant clusters with less activity in somatoform patients included the bilateral parahippocampal gyrus, the left amygdala, the left postcentral gyrus, the left superior temporal gyrus, the left posterior insula, and the bilateral cerebellum. These findings indicate that disturbed emotional empathy of somatoform disorder patients is linked to impaired emotion recognition and abnormal activity of brain regions responsible for emotional evaluation, emotional memory, and emotion generation.

RESUMEN

OBJECTIVES: Somatoform disorder patients demonstrate a disturbance in the balance between internal and external information processing, with a decreased focus on external stimulus processing. We investigated brain activity of somatoform disorder patients, during the processing of rewarding external events, paying particular attention to the effects of inpatient multimodal psychodynamic psychotherapy. METHODS: Using fMRI, we applied a reward task that required fast reactions to a target stimulus in order to obtain monetary rewards; a control condition contained responses without the opportunity to gain rewards. Twenty acute somatoform disorder patients were compared with twenty age-matched healthy controls. In addition, 15 patients underwent a second scanning session after participation in multimodal psychodynamic psychotherapy. RESULTS: Acute patients showed diminished hemodynamic differentiation between rewarding and non rewarding events in four regions, including the left postcentral gyrus and the right ventroposterior thalamus. After multimodal psychodynamic psychotherapy, both regions showed a significant normalization of neuronal differentiation. CONCLUSION: Our results suggest that diminished responsiveness of brain regions involved in the processing of external stimuli underlies the disturbed balance of internal and external processing of somatoform disorder patients. By providing new approaches to cope with distressing events, multimodal psychodynamic psychotherapy led to decreased symptoms and normalization of neuronal activity.

RESUMEN

The aim of this study is to investigate whether there is a difference in the amount of fear of the advancement (progression) and return (relapse) of cancer shown by terminal cancer patients and those in curative therapy. The cohort consists of 291 rehabilitation patients, main diagnoses were colonic/rectal-, breast- and prostate cancer. The patients were questioned using the fear of progression questionnaire (PA-F-KF) and a Five-Item Fear of Relapse/Recurrence Scale. Patients in palliative care and those in curative therapy are equally fearful of the disease progressing. When comparing both groups for fear of relapse however, those patients in palliative care are more anxious. This apparently paradoxical result can be seen as being an expression of the highly debilitating fear experienced by terminally ill cancer patients. Simultaneously, patients try to keep up their hope by unconsciously reinterpreting the actual progress of the disease as being a potential relapse.
