Depression can be viewed as both a symptom of fibro and a co-morbid condition. Often when a teenager is finally referred to me for fibro he will report a long-standing depression. Childhood onset depression is slippery and often overlooked. Interestingly enough, symptoms of depression in children and teenagers can include vague aches and pains, particularly headaches and back pain often associated with fibro. As a co-morbid condition, depression is virtually indistinguishable from fibro. Chronic pain and illness are depressing. The question may be whether fibro is a symptom of depression or depression a symptom of fibro, or whether they are simply partners. In either case, it is important to note:- Fibro symptoms are known to be alleviated in many cases by SSRIs (like Prozac), SNRIs (like Cymbalta) and other anti-depressant groups– SSRIs can cause detrimental side effects and suicidal ideation- While psychodynamic therapy might help adults with depression, it is not a good therapeutic choice for an adolescent. Go with CBT.- Ritalin can cause or exacerbate depression in teens– A severe depression may require hospitalization In every case, depression should be taken seriously; it’s a serious matter.
