These disorders can impact an individual's ability to function in daily life and can vary in severity from mild to severe. Common psychiatric disorders include depression, anxiety disorders, bipolar disorder, schizophrenia, and eating disorders. Research in this area focuses on understanding the causes, symptoms, and treatment options for these conditions, as well as developing interventions to improve the lives of those affected by psychiatric disorders.
