Which psychiatric disorder is most commonly diagnosed, yet least commonly treated?

Depression is the psychiatric disorder that is most commonly diagnosed yet least commonly treated. This situation arises due to a variety of factors, including stigma, lack of awareness regarding treatment options, and the tendency for individuals to minimize or overlook their symptoms.

Many people experiencing depression may not seek help due to feelings of shame or a belief that they can cope on their own. Additionally, healthcare systems may not always adequately screen for depression during routine visits, leading to underdiagnosis and undertreatment. Even when diagnosed, some individuals may not receive appropriate therapy or medication due to barriers such as healthcare access, cost, or a lack of mental health resources.

In contrast, bipolar disorder, Alzheimer's disease, and various forms of dementia, while significant concerns, tend to be more overtly recognized in clinical settings. Treatments for these conditions often involve structured care plans and support systems that may not be as readily established for depression. Furthermore, current awareness campaigns and education may enhance recognition and treatment adherence for these other disorders compared to depression.
