Current theories explaining the causes and treatments of mental disorders include biological perspectives, which focus on genetic and neurological factors, as well as social-cognitive perspectives, which consider the influence of environmental factors and cognitive processes. These theories help psychologists understand why people develop conditions like depressive disorders and bipolar disorder, leading to more effective treatment strategies. Additionally, the medical model approach views psychological disorders as mental illnesses with physical causes that can be diagnosed and treated. Biopsychosocial approach combines biological, psychological, and social factors in understanding mental health issues. These theories guide therapists in providing appropriate interventions to alleviate suffering and prevent future occurrences of psychological disorders.
