What are the causes of mood disorders, such as depression and bipolar disorder? Mood disorders like depression and bipolar disorder arise from a combination of genetic, biological, environmental, and psychological factors. Genetics play a crucial role, as individuals with a family history of mood disorders are at higher risk. Neurochemical imbalances, particularly in serotonin, dopamine, and norepinephrine levels, contribute to mood instability. Additionally, chronic stress, trauma, hormonal changes, and substance abuse can trigger or worsen symptoms. Environmental factors such as social isolation, financial stress, or major life changes also impact mental well-being.
