These factors include biological predispositions such as genetics, brain chemistry, and neurological functioning, alongside environmental influences like family history, social circumstances, and life experiences. While traumatic life events can certainly contribute to the development or exacerbation of mental health conditions for some individuals, they are not universally the primary cause of most mental illnesses.

Understanding mental health through a biopsychosocial model highlights the multifaceted nature of mental illness. This model considers biological factors (such as genetic vulnerability), psychological factors (like personality traits and coping strategies), and social influences (including life stressors and support systems).
