A depression screening quiz typically asks whether the test-taker is experiencing various symptoms such as loss of appetite, changes in sleep, feelings of hopelessness and lack of interest in activities, according to WebMD. The test also asks the taker to specify how long the symptoms have been present.
Individuals experiencing clinical depression exhibit a variety of mental and physical symptoms, but the symptoms vary from person to person. For example, some patients experience a loss of appetite, while others develop an increased appetite, according to WebMD. Mental symptoms can include a sad mood; the loss of interest in activities that the patient used to enjoy; feelings of hopelessness, worthlessness or guilt; an inability to concentrate; or thoughts of suicide. Physical symptoms often include a lack of energy, in addition to changes in appetite, weight or sleep habits. Doctors diagnose depression when the patient has been experiencing several of these symptoms for an extended period of time.
As of 2015, current treatments for depression include drug therapy, psychotherapy and exercise, explains WebMD. In many cases, patients combine these treatments for optimal results. When the patient is experiencing severe depression and doesn't respond to these treatments, doctors may treat depression with electroconvulsive therapy, transcranial magnetic stimulation or vagus nerve stimulation.
