Body stability is controlled by the postural system and can be affected by fear and anxiety. Few studies have addressed freezing posture in psychiatric disorders. The purpose of the present study was to assess posturographic behavior in 30 patients with social anxiety disorder (SAD) and 35 without SAD during presentation of blocks of pictures with different valences. Neutral images consisted of objects taken from a catalog of pictures, negative images were mutilation pictures and anxiogenic images were related to situations regarding SAD fears. While participants were standing on a force platform, similar to a balance, displacement of the center of pressure in the mediolateral and anteroposterior directions was measured. We found that the SAD group exhibited a lower sway area and a lower velocity of sway throughout the experiment independent of the visual stimuli, in which the phobic pictures, a stimulus associated with a defense response, were unable to evoke a significantly more rigid posture than the others. We hypothesize that patients with SAD when entering in a situation of exposure, from the moment the pictures are presented, tend to move less than controls, remaining this way until the experiment ends. This discrete body manifestation can provide additional data to the characterization of SAD and its differentiation from other anxiety disorders, especially in situations regarding facing fear.  相似文献

The tremor in patients with anxiety was supposed to be an enhanced physiological tremor. However no detailed clinical and electromyographic examination of tremor in patients with anxiety has been published. It has been also supposed that propranolol or benzodiazepines may influence the tremor The aim of this investigation was to establish the clinical and electromyographic pattern of tremor in patients with anxiety and to compare the effects of propranolol and alprazolam treatment. One hundred and twenty patients with tremor and generalized anxiety disorder were investigated. Tremor was scored clinically by the Webster Tremor Scale. Electromyographic examination of tremor activity from antagonistic hand muscles was performed. Sixty patients were treated with alprazolam and propranolol, in an open, crossover design, while the other sixty patients received no particular treatment for the tremor The patients were randomly assigned to treatment with propranolol, alprazolam, or received no tremor treatment. Our results revealed a postural and kinetic tremor with characteristics of an enhanced physiological tremor. Tremor involved only upper limbs and no other body parts. Treatment with propranolol or alprazolam had similar favorable effect on tremor. In conclusion tremor in generalized anxiety disorder is an enhanced physiological tremor The kinetic tremor disturbs patients and particular tremor treatment with propranolol or alprazolam should be applied.  相似文献

Background and Objectives The line bisection error to the left of the true center has been interpreted as a relative right hemisphere activation, which might relate to the subject''s emotional state. Considering that patients with generalized anxiety disorder (GAD) or treatment-resistant depression (TRD) often have negative emotions, we hypothesized that these patients would bisect lines significantly leftward. Methods We tried the line bisection task in the right-handed healthy volunteers (n = 56), GAD (n = 47) and TRD outpatients (n = 52). Subjects also completed the Zuckerman - Kuhlman Personality Questionnaire, the Zuckerman Sensation Seeking Scales, and the Plutchik-van Praag Depression Inventory. Results GAD patients scored highest on the Neuroticism-Anxiety trait, TRD patients scored highest on depression, and both patients scored lower on the Sociability trait. Patients with GAD also bisected lines significantly leftward compared to the healthy subjects. The Frequency of the bisection error was negatively correlated with Disinhibition-Seeking in the healthy subjects, and with Total sensation-seeking and Experience-Seeking in GAD patients, while the Magnitude of the line bisection error was negatively correlated with depression in TRD patients. Conclusions The study suggests a stronger right hemispheric activation, a weaker left activation, or both in the GAD, instead of TRD patients.  相似文献

Generalized anxiety disorder (GAD) has harmful effects on physical and mental health and quality of life. Coloring therapy has been reported to have a positive effect on improving patient anxiety and depression. But there are no reported clinical trials examining their effectiveness as a treatment for GAD. This study was planned to evaluate the effectiveness of coloring therapy combined with conventional therapy in improving anxiety, depression, and positive and negative emotions with GAD. This randomized controlled study comprising 88 GAD patients was selected for intervention in different wards. The control group (n = 45) was given conventional antianxiety medication and physical therapy, and the experimental group (n = 43) received coloring therapy combined with conventional therapy. The Self‐Rating Depression Scale, Self‐Rating Anxiety Scale (SAS), Hamilton Depression Scale, Hamilton Anxiety Scale (HAMA), and Positive and Negative Affect Scale were assessed in both groups before and 3 weeks after the intervention. After the intervention, there were statistical differences in intra‐ and inter‐group comparisons of anxiety, depression, and positive and negative mood scales in the experimental and control groups (p < .05). The minus in anxiety/positive emotions pre‐ and postintervention in the experimental group was statistically significant compared to that in anxiety/positive emotions pre‐ and postintervention in the control group (HAMA: d = 1.45, 95% confidence interval [CI] (0.34, 2.57), p = .011; SAS: d = 3.87, 95% CI (1.73,6.00), p = .001; positive: d = 1.76, 95% CI (0.17, 3.34), p = .030). The minus in depressive/negative emotions pre‐ and postintervention in the experimental group was not statistically significant compared with that in depressive/negative emotions pre‐ and postintervention in the control group (p > .05). For GAD patients, adding coloring therapy based on conventional drug therapy and physical therapy can not only reduce depression and negative emotions but also have better effects on reducing anxiety and improving positive emotions than conventional therapy.  相似文献

The objective of the present study was to evaluate memory performance in tasks with and without affective content (to confirm the mood congruency phenomenon) in acutely admitted patients with bipolar I disorder (BD) and major depression disorder (MDD) and in healthy participants. Seventy-eight participants (24 BD, 29 MDD, and 25 healthy controls) were evaluated. Three word lists were used as the memory task with affective content (positive, negative and indifferent). Psychiatric symptoms were also evaluated with rating scales (Young Mania Rating Scale for mania and Hamilton Depression Rating Scale for depression). Patients were selected during the first week of hospitalization. BD patients showed higher scores in the word span with positive tone than MDD patients and healthy controls (P = 0.002). No other difference was observed for tests with affective tone. MDD patients presented significantly lower scores in the Mini-Mental State Exam, logical memory test, visual recognition span, and digit span, while BD patients presented lower scores in the visual recognition test and digit span. Mood congruency effect was found for word span with positive tone among BD patients but no similar effect was observed among MDD patients for negative items. MDD patients presented more memory impairment than BD patients, but BD patients also showed memory impairment.  相似文献

Previous functional neuroimaging studies found that the amygdala and other limbic regions may play a substantial role in social anxiety disorder (SAD). However, more widely distributed large-scale brain systems may be involved in cognitive processing in SAD patients when confronted with social situations. We employed functional MRI (fMRI) to investigate local brain activation of patients with SAD (n=6) and healthy controls (HC, n=9) during cognitive work. During fMRI scanning, subjects performed a social situation task using a block design paradigm in which the task and control trials were performed by turn. The patients with SAD showed higher anxiety levels during scanning in all social situations. The HC group showed greater common activation in the posterior cingulate cortex (PCC), cuneus, occipital gyrus, and cerebellum. Although the patients with SAD showed activation patterns similar to that of the HC group, they showed comparatively significant decreased activation in the left cerebellum, left precuneus, and bilateral PCC. The present study demonstrates that SAD may involve dysfunction of a broad neuronal network including the limbic system, parieto-posterior cortex and cerebellum. The findings contribute to previous findings that revealed abnormal activities of emotion-related regions including the amygdala and insular cortex during facial perception in SAD.  相似文献
