The comorbidity of anxiety-related disorders and insomnia: An analysis of mechanisms

Abstract

Anxiety is a common epidemiological mental disorder that includes Generalized Anxiety Disorder (GAD), panic disorders (PD), and phobias; its causes include anxiogenic genes and the living environment; insufficient or low sleep quality can trigger and intensify anxiety disorders. Neurotransmitters play an essential role in operating our bodys crucial functions, such as emotional regulation and sleep, so much neuroimaging evidence suggests they are critical to forming anxiety and insomnia. Previous longitudinal studies suggest that insomnia is a significant index and predictor of mental health and, therefore, can also be generated from mental disorders due to their comorbidity. This short review will posit the formation of insomnia caused by the presence of anxiety disorders in patients with both insomnia and anxiety symptoms. This review further discusses some therapies that enhance and improve sleep quality among insomnia problems. It mostly debates the thesis that anxiety is the driving factor and precedes insomnia and its related neuropathological developments that can be highlighted from neurotransmitter systems and sleeping models such as the hyperarousal model. Overall, it is significant that individuals with anxiety-related disorders have lower sleeping qualities that cause functional impairment and lower subjective living qualities.
