Anxiety and fear serve adaptive functions and include wide-ranging subjective, physiological, behavioral, and cognitive responses. When these reactions are present chronically, and to a heightened degree that generalizes to signals beyond those that are objectively dangerous, one sees emergence of clinical anxiety disorders. Historically, anxiety disorders have been conceptualized as disruptions in fear processing, though more recent accounts also highlight changes in emotional reactivity beyond fear and deficits in emotion regulation. In this chapter, we review the neural circuitry relevant for fear processing and for emotional reactivity and regulation more broadly. We then review neuroimaging studies of social anxiety disorder, specific phobia, generalized anxiety disorder, panic disorder, and posttraumatic stress disorder. We highlight areas of overlap between disorders as well as disorder-specific perturbations.

Anxiety disorders are the most common psychiatric disorders among adults in the United States.

The treatment literature for anxiety disorder has grown tremendously since the 1980s, and both psychotherapy and medications may prove beneficial for people with anxiety disorders.

Anxiety disorders are the most common mental disorders in childhood and adversely affect the functioning of children in various important areas of their life. According to contemporary international research, girls seem to be more prone to the appearance of anxiety disorder. This survey was conducted on a sample of 461 pupils of grades E and F in urban and semi-urban areas of Greece and confirmed the findings of corresponding international studies. In particular, it was found that gender significantly affects the occurrence of specific phobia (fear of bodily injury), generalized anxiety disorder, panic-agoraphobia, social phobia and separation anxiety. Typically, girls appeared to have higher levels of anxiety in various events in their lives. It has been shown that early detection and early intervention, along with the strengthening of counseling parents, contribute significantly to the smooth psychosomal development of children with anxiety disorders.

Chapter 7 summarizes the epidemiology, clinical characteristics, and evidence for pharmacological treatment options of generalized anxiety disorder, panic disorder, agoraphobia, specific phobia, and social anxiety disorder. With regard to the pharmacological management, serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) represent the well-established first-line medication for generalized anxiety disorder (GAD), panic disorder, agoraphobia, and social anxiety disorder. In GAD, also the calcium channel modulator pregabalin can be regarded as evidence-based treatment option. In simple cases of specific phobia, however, the initiation of a pharmacotherapy is not recognized as standard treatment according to international treatment guidelines and psychotherapeutic interventions should be preferred. Besides illustrating the pharmacological treatment options, we described the actualized diagnostic criteria for anxiety disorders established in the newly introduced fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V).

BackgroundStructural models of emotional disorders propose that anxiety disorders can be classified into fear and distress disorders. Sources of evidence for this distinction come from genetic, self-report and neurophysiological data from adults. The present study examined whether this distinction relates to cognitive processes, indexed by attention bias towards threat, which is thought to cause and maintain anxiety disorders.MethodDiagnostic and attention bias data were analysed from 435 children between 5 and 13 years of age; 158 had principal fear disorder (specific phobia, social phobia or separation anxiety disorder), 75 had principal distress disorder (generalized anxiety disorder, GAD) and 202 had no psychiatric disorder. Anxious children were a clinic-based treatment-seeking sample. Attention bias was assessed on a visual-probe task with angry, neutral and happy faces.ResultsCompared to healthy controls, children with principal distress disorder (GAD) showed a significant bias towards threat relative to neutral faces whereas children with principal fear disorder showed an attention bias away from threat relative to neutral faces. Overall, children displayed an attention bias towards happy faces, irrespective of diagnostic group.ConclusionsOur findings support the distinction between fear and distress disorders, and extend empirically derived structural models of emotional disorders to threat processing in childhood, when many anxiety disorders begin and predict lifetime impairment.
