Risk factors for suicide
Overview
Plain-Language Overview
The risk factors for suicide are characteristics or conditions that increase the likelihood of a person attempting or dying by suicide. These factors affect the mental health and overall well-being of individuals, often involving the brain's emotional regulation and stress response systems. Common risk factors include mental illnesses such as depression and anxiety, substance abuse, and experiences of trauma or significant life stressors. Social isolation and lack of support networks also play a critical role. Understanding these factors helps identify individuals who may be at higher risk and informs prevention efforts.
Clinical Definition
Risk factors for suicide refer to a set of biological, psychological, and social variables that increase the probability of an individual engaging in suicidal behavior. The core pathology involves dysregulation of neurotransmitter systems (e.g., serotonin), impaired stress response mechanisms, and underlying psychiatric disorders such as major depressive disorder, bipolar disorder, and schizophrenia. Additional contributors include substance use disorders, chronic medical illnesses, and a history of previous suicide attempts. Environmental and psychosocial stressors, including childhood abuse, social isolation, and access to lethal means, further elevate risk. These factors collectively disrupt cognitive and emotional processing, leading to increased suicidal ideation and behaviors with significant morbidity and mortality.
