Do Not be Afraid: Novel Approaches to the Treatment of Anxiety Disorders

Abstract

Introduction

Anxiety disorders (AD) are associated with significant morbidity and often are chronic and resistant to the treatment. A fascinating aspect of AD is the interplay of genetic and experiential factors. It is stablished that abnormal genes predispose to pathological anxiety states; however evidence clearly indicates that traumatic life events and stress are also etiologically relevant. The behavioral theories of anxiety postulates that anxiety is a conditioned response to a specific environmental stimulus. There may be two ways to neutralize fear conditioning either by facilitating a process called extinction or by blocking a process called reconsolidation.

Objectives

Review novel approaches to the treatment of AD.

Aims

To update on treatment for AD.

Methods

A literature search was performed on PubMed database.

Results

Cognitive behavioral therapies use exposure techniques, in which the patient has to confront the fear-inducing stimuli in a safe environment in order to facilitate the fear extinction. The therapy is often context-specific, so one way of strengthen extinction learning is by boosting NMDA receptor activation, either with direct acting agonists (D-cycloserine) or with indirect glycine enhancing agents (selective glycine reuptake inhibitors). Memory reconsolidation is based on the notion that memories are dynamic rather than stable. Reactivation of a memory can return it to a labile state from which it must be reconsolidated. Blocking reconsolidation is a therapeutic opportunity of update and alter the memory, weakening traumatic memories. Beta-blockers and opioids may disrupt this process.

Conclusions

Psychotherapy and psychopharmacology may have a synergistic role in AD treatment.
