They can disrupt daily life and may lead to difficulties in relationships, work, and self-care. Common types of mental disorders include depression, anxiety disorders, and bipolar disorder. These disorders can arise from a combination of genetic, biological, environmental, and psychological factors. Treatment options often include therapy, medication, and lifestyle changes, which can help individuals manage their symptoms and improve their quality of life.
