Unraveling The Neurobiological Mechanisms And Therapeutic Challenges In Anxiety Disorders: A Comprehensive Review
Year: 2024
Type: article
Abstract: This comprehensive review explores the complex neurobiological underpinnings of anxiety disorders and the challenges associated with developing effective pharmacological treatments. The article examines the roles of key neurotransmitter systems, including serotonergic and GABAergic pathways, in anxiety regulation. It discusses the involvement of the hypothalamic-pituitary-adrenal (HPA) axis and its dysregulation in anxiety disorders. The review also addresses the molecular mechanisms underlying the therapeutic effects of antidepressants and anxiolytics, with a focus on the adenylate cyclase-cAMP-protein kinase A signaling cascade and its impact on gene transcription. Additionally, it explores the potential of novel targets, such as neuropeptide systems and glutamatergic receptors, in anxiety treatment. The article highlights the limitations of current preclinical models and the difficulties in translating promising compounds into clinically effective therapies. It concludes by emphasizing the need for a multidisciplinary approach to overcome the challenges in anxiety drug development and to address unmet medical needs in this field.
