Specifically altered brain responses to threat in generalized anxiety disorder relative to social anxiety disorder and panic disorder
BACKGROUND Despite considerable effort, the neurobiological underpinnings of hyper-responsive threat processing specific to patients suffering from generalized anxiety disorder (GAD) remain poorly understood. The current functional magnetic resonance imaging (fMRI) study aims to delineate GAD-specific brain activity during immediate threat processing by comparing GAD patients to healthy control...
متن کاملEvidence for disturbed cortical signal processing and altered serotonergic neurotransmission in generalized anxiety disorder.
BACKGROUND Current pathophysiological concepts of generalized anxiety disorder (GAD) assume a disturbed exteroceptive sensory system. Furthermore, central serotonergic neurotransmission has been shown to play an important role in anxiety disorder. Cortical signal processing as measured by auditory evoked potentials (AEPs) may reflect the integrity of the exteroceptive sensory system. Because a ...

The present study population includes all state universities, Islamic Azad Universities of Tabriz students a...
متن کاملCortical functional activity in patients with generalized anxiety disorder
BACKGROUND The neurological correlates of Generalised Anxiety Disorder (GAD) are not well known, however there is evidence of cortical dysregulation in patients with GAD. The aim of the study was to examine cortical functional activity in different cerebral regions in patients with GAD using electroencephalogram (EEG) nonlinear analysis to evaluate its contribution of anxiety severity. METHOD...
متن کاملDiminished autonomic neurocardiac function in patients with generalized anxiety disorder
BACKGROUND Generalized anxiety disorder (GAD) is a chronic and highly prevalent disorder that is characterized by a number of autonomic nervous system symptoms. The purpose of this study was to investigate the linear and nonlinear complexity measures of heart rate variability (HRV), measuring autonomic regulation, and to evaluate the relationship between HRV parameters and the severity of anxie...
