Physical Exam & Other Testing Methods
Upon seeking expert’s advice on depression, keep in mind that no one test would make depression as a conclusive diagnosis. It will require series of test and exams. Most physicians would usually rule out other serious medical diseases that may have similar presentations as that of depression. Examples of these are thyroid disease and Vitamin D deficiency. First and foremost, the doctor will perform a physical exam with the primary focus on the neurological and endocrine systems. In hypothyroidism, the thyroid glands are underactive which is manifested by irritability, weight gain, cold intolerance and depressive symptoms. Also, many central nervous system disorder and injuries can result in depression. Conditions associated with depression are central nervous system tumors, head trauma, stroke, syphilis and various cancers. Corticosteroid medication such as prednisone usually taken by individuals with asthma, rheumatoid arthritis, and lupus is also a possible culprit for the depression. Similarly, withdrawal from drugs like amphetamines, over the counter appetite suppressants and illegal steroids may cause depressive withdrawal symptoms. MRI and CT scan of the brain might be performed to rule out brain tumors.
