Now a recent study demonstrates an important way that this is so.
Reduced levels of BDNF – described as a nerve repair agent – were recently found in Chronic Fatigue Syndrome and multiple sclerosis. The levels found – less 25% of normal – were stunningly low, and this suggested that neuron functioning was taking a real hit in both these disorders. Given the nerve damage found in MS, that result was expected for MS – but not in ME/CFS.
A recent Fibromyalgia BDNF study seems to portray a very different disorder.
