Depression is highly treatable but it can't be attended to if it isn't diagnosed! Without exception, everyone feels sad, lonely, and upset from time to time. But clinical, or major, depression is a mental illness marked by persistent, debilitating feelings of sadness. In fact, for U.S. citizens ages 15 to 44, major depression is the leading cause of mental disability! Because of this, doctors have developed specific, effective methods testing for and diagnosing depression. Doing so starts with a physical examination. A physician may ALSO order laboratory tests of blood and urine during this exam. Although there is no specific "test" for depression, urine and blood work will allow the doctor to identify any major health concerns that may contribute to signs of the illness. For example, he'll look for conditions like hypothyroidism, which is caused by an under active thyroid gland. The physician will also want to ensure that symptoms aren't due to side effects from any medications or illegal drugs. After ruling out physical health problems, a doctor will complete a diagnostic evaluation. During this conversation, he'll ask inquire about a family history of depression and other mental illnesses. The physician will then ask whether the patient experiences persistent sad, anxious, or empty moods. He'll also want to know if the patient has lost pleasure in previously enjoyable activities and people. An affirmative answer to either of these questions is required for a diagnosis of depression to be made. Additionally, the patient must have at least FIVE more depressive symptoms, as dictated by the American Psychiatric Association. These symptoms include physical changes, like fatigue and decreased energy, sleep disturbances, changes in appetite and/or weight and recurrent bodily complaints, like aches and pains or digestive upset. The symptoms ALSO be emotional and mental. Decreased memory and concentration, poor self-image or self-esteem, feelings of hopelessness and pessimism, and feelings of guilt. If a patient experiences some or all of these over a period of AT LEAST two weeks, a doctor will likely make a diagnosis of depression. Being diagnosed with a mental illness can be disheartening and frightening, but with treatment, depression is a HIGHLY curable condition! For this reason, it's vital to see a medical professional if you're experiencing signs of clinical depression.
