“Background: Depersonalization disorder (DPD) entails distressing alterations in self-experiencing. However, it has long been recognized that depersonalisation symptoms occur in other disorders, particularly anxiety and panic. One strand of research proposes that depersonalization phenomenology arises through altered autonomic arousal in response to stress. Sampling and Methods: We sought to examine profiles of anxiety symptoms through a secondary data analysis of individual items and factor subscales on the Beck Anxiety Inventory Torin 2 in vivo (BAI), comparing two relatively large patient samples with DPD or with a variety of anxiety conditions, respectively. The DPD sample (n = 106) had a lower overall BAI

score than the combined anxiety disorders group (n = 525). Results: After controlling for this as well as for potential confounders such as age and gender, the DPD group presented significantly lower scores on the panic subscale, marginally lower scores on the autonomic

Selleck AZD5153 subscale and significantly higher scores on the neurophysiological subscale of the BAI. Conclusions: These differences imply similarities between the cognitive components of DPD and anxiety disorders while physiological experiences diverge. The findings encourage future research looking at direct physiological measures and longitudinal designs to confirm the mechanisms underlying different clinical manifestations of anxiety. (C) 2014 S.

“Purpose of studyTo discuss studies in humans and animals revealing the ability of foods to benefit the brain: new information with regards to mechanisms of action and the treatment of neurological and psychiatric disorders.Recent findingsDietary GSK923295 in vitro factors exert their effects

on the brain by affecting molecular events related to the management of energy metabolism and synaptic plasticity. Energy metabolism influences neuronal function, neuronal signaling, and synaptic plasticity, ultimately affecting mental health. Epigenetic regulation of neuronal plasticity appears as an important mechanism by which foods can prolong their effects on long-term neuronal plasticity.SummaryThe prime focus of the discussion is to emphasize the role of cell metabolism as a mediator for the action of foods on the brain. Oxidative stress promotes damage to phospholipids present in the plasma membrane such as the omega-3 fatty acid docosahexenoic acid, disrupting neuronal signaling. Thus, dietary docosahexenoic acid seems crucial for supporting plasma membrane function, interneuronal signaling, and cognition. The dual action of brain-derived neurotrophic factor in neuronal metabolism and synaptic plasticity is crucial for activating signaling cascades under the action of diet and other environmental factors, using mechanisms of epigenetic regulation.”
