We provide evidence that GAD is associated with disrupted white-matter coherence of posterior right hemisphere regions, which may partly sustain the impaired cognitive regulation of anxiety. Future diffusion imaging investigations are expected to better elucidate the communication between the parietal cortex and other right hemisphere regions in sustaining the cognitive processing of social and emotional stimuli in patients with GAD.
Background: It is possible to find an organic cause just for 1/3 of patients admitted to hospital with chest pain [1]. For the other 2/3 we are dealing with Unexplained Chest Pain [2]. Many studies demonstrated that in a high percentage of people that suffer of UCP there are mental disorders and unfavourable social and psychological factors [3,4,5]. Aim: The aim of this study was to estimate prevalence and to outline the psychological, social, anxious, depressive and somatoform state of patients admitted to emergency ward. Method: We recruited 319 patients, 169 treated in Udine´s Emergency ward for chest pain and a control group of 150 patients that went to their family doctor with other symptoms. Each of them completed self-administered tests searching socio-demographic characteristics, anxiety, depression, somatization, alexithymia, stress factors and child abuse. After 3 months we selected, using the hospitals database, patients that had confirmed diagnosis of UCP. Results: Prevalence of UCP in patients treated in Udine's emergency room was 45,5% (n77). We found a statistically significant difference between patients with UCP and control healthy group in the somatization subscale of SCL90 (χ2=18,2; p< 0,0001) and anxiety subscale of HADS (χ2=21,5; p< 0,0001). Conclusions: A high percentage of hospitalized patients in the emergency ward for chest pain did not receive diagnosis of an organic pathology. It's possible to find in these patients a greater tendency to somatization and presence of anxiety symptoms. This data is in line with what recent literature shows.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
