Diagnosis of Depressive Disorder

Reading time: 2 min

Despite the efforts by the scientific community to find a test that would enable an accurate diagnosis to be made with objectivity, depressive disorders, at the moment, do not have any specific technique available useful for making this diagnosis.

CT, MRI or scan cancelled or unnecessary

At the moment, none of the imaging tests that are used to “see” the brain (CT scan, scanner, magnetic resonance, radiography, SPECT, PET, functional magnetic resonance, the electroencephalogram [EEG], blood analysis—including serotonin and/or lithium—, or genetic studies using saliva or mucosa from the mouth) are useful for diagnosing depressive disorders.

Doctor talking to a patient

The only relevant information source for the diagnosis of this illness, is the clinical interview with the patient (and, often, with a close relative). It is also important to highlight that the use of scales and clinically structured interviews cannot ensure the infallibility of the diagnosis.
