Study on the progress of three pathways in anxiety disorders

Abstract

An overview is presented in this review, which delves into the neural pathways associated with anxiety disorders. The emphasis is placed on the amygdala and prefrontal cortex circuit, the GABAergic pathway, and the serotonin pathway. The amygdala-prefrontal cortex circuit is essential to processing fear and making decisions; anxiety disorders have been linked to disruption in this circuit. The GABAergic pathway, characterized by the release of GABA and inhibition of neuronal activity, is implicated in anxiety through its role in regulating neuronal excitability. Altered GABAergic function is associated with various anxiety disorders. The serotonin pathway, involving the release of serotonin and modulation of mood and stress responses, is also involved in anxiety disorders. Medications targeting these pathways can help modulate the circuits and alleviate anxiety symptoms. Awareness of these pathways is still limited, though, because anxiety is a complicated illness influenced by a number of factors. The main goals of future research should be the development of individualized treatment plans for anxiety disorders and better clarifying the processes of dysregulation.
