There is no single cause for mental disorders

What causes mental illness?

:

Biological perspective

Factors such as genetics, neurobiology, and hormonal responses can influence psychopathology.

Psychological perspective:

Dysfunctional thoughts, feelings, and behaviors can lead to psychopathology.

Sociocultural perspective

Social and cultural factors can influence how we think about abnormal behavior.

Many theorists recognize the need for a biopsychosocial viewpoint that acknowledges that biological, psychological, and social factors all interact and play a role in psychopathology and treatment (Hooley er al, 2019).
