although there are known, effective treatments for depression, fewer than half of those affected in the world (in some countries, fewer than 10%) receive such treatments. Barriers to effective care include a lack of resources, lack of trained health care providers, and social stigma associated with mental disorders. Another barrier to effective care is inaccurate assessment. Even in some high-income countries, people who are depressed are not always correctly diagnosed, and others who do not have the disorder are occasionally misdiagnosed and prescribed antidepressants.
