CFS or depression - what are the differences
Physicians can be very naughty and intellectually lazy when it comes to diagnosing CFS. They are all too willing to label patients as depressed because this leads on to a straightforward and well recognised management protocol, namely, anti-depressants, exercise and, if you are lucky, counselling. Anti-depressants in normal doses will make you worse, as will exercise. Counselling depends on the counsellor: if they do not believe CFS exists then you are well and truly stuffed.
There are clear distinctions between the two conditions, including the following:
1: Exercise: this makes CFS patients much worse but can be positively therapeutic in pure depression. This is the main difference! Also see CFS - Psychological or Physical?
2: Muscle tenderness and pain is common in CFS, and unusual in depression.
3: Response to alcohol and anti-depressants. These almost invariably make CFS patients worse, but depressed patients often get benefits.
4: Sleep disturbance: in CFS, the biological clock is moved on so patients go to sleep late and wake up late in the morning. With depression, one expects to see early morning wakening.
5: Adrenal function. In CFS, this is usually depressed, whereas in depression, there may be associated anxiety, with raised levels of cortisol- see adrenal stress profile.
6: CFS patients often have poor immunity, with recurrent infections. This is not generally a feature of depression.
7: If you can get the tests done, then there will be differences in neuro-psychometric testing, which demonstrate a different type of cognitive disturbance, memory lose and mental agility in both illnesses. Furthermore, SPECT and PET scans demonstrate diminished metabolism in the brain stem, medial and frontal lobes of the cerebral cortex in ME, whilst in depression, diminished metabolism is more widespread and the frontal lobes are chiefly affected.
