According to the 2017 data of World Health organization approximately 800 million individuals commit suicide annually. After understanding that psychiatric disorders start the inflammation process by suppressing the brain, a number of studies using neutrophil/lymphocyte ratio, platelet/lymphocyte ratio and monocyte/lymphocyte ratio have been conducted. Platelet/lymphocyte ratio, neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio and other hemogram parameters may be a marker in predicting suicide. In addition, the determination of the relationship between these inflammatory markers and the cyclicity/seasonality of suicide can provide a basis for preventive mental health measures.
