Suicide is a serious public health issue that affects people all around the world. Suicidal behaviour varies by gender, age group, geographic region, and sociopolitical context, and is associated with a variety of risk variables, implying aetiological heterogeneity. Although no effective algorithm for predicting suicide exists in clinical practise, better awareness and comprehension of clinical, psychological, sociological, and biological aspects may aid in the identification of high-risk people and therapy choices. Treatments for mental diseases that are psychotherapeutic, pharmacological, or neuromodulatory can often prevent suicidal conduct; also, regular follow-up by mental health services of people who attempt suicide is critical in preventing future suicidal behaviour.
