Platelet Function in Mood Disorders: Interplay, Clinical Implications, and Future Perspectives - A Narrative Review

Mood disorders, encompassing major depressive disorder and bipolar disorder, present complex etiologies involving neuroanatomical, neurotransmitter, and inflammatory mechanisms. Recent research explores the role of platelets, traditionally associated with hemostasis, in the pathophysiology of mood disorders. We examine neuroanatomical insights, neurotransmitter dysregulation, and the link between inflammation and mood disorders, emphasizing the complex nature of mood disturbances. Emerging evidence of altered platelet function in mood disorders and the therapeutic potential of antiplatelet agents and serotonin reuptake inhibitors are discussed. While personalized medicine holds promise, further research is needed to fully comprehend this evolving field. This review offers comprehensive insights into mood disorder diagnosis, intervention, and pathophysiology. In this review, a comprehensive literature search was conducted using databases such as PubMed, Scopus, and Web of Science. The search focused on articles published from 2000 to 2023, using keywords like "platelet function," "mood disorders," and "neurotransmitter dysregulation." We included studies that specifically investigated the role of platelets in mood disorders, encompassing various study designs and population demographics.
