I'm wondering if the light therapy will be useful for ME though? I had a traumatic brain injury in an accident but after having ME for 20 off years. Previously used a light box to try and help the ME but it didn't and I found that the morning photo-phobia and other normal for me symptoms were so intense that I was worse off.
Having ME on top of other things (like the brain injury) makes recovery hard from anything.
My ME started with an acute viral onset and fever/delirium.
It could be that acute viral onset causes brain injury. It really does seem strange to me that the symptoms of brain injury sound so similar, CFS is often triggered by EBV, and we're increasingly aware of the role EBV can play in brain injury for MS.
I had a mate who only semi-recovered from glandular fever, got in a car crash, and two years later developed lots of symptoms which were dismissed as psychosomatic. A couple of years later he was diagnosed with a brain injury, and put on an appropriate rehabilitative programme.
It could be that our brains can manage a certain amount of damage, but the more it adds up, the more things go wrong - particularly if you're being told by your doctors that your problems are just deconditioning, and you'll return to full health if you just work through it.
(Not the I'm saying this is the 'cause' of CFS, but I personally expect that neurological damage that directly results from certain viral infections and the bodie's response to them is likely to be significant for a lot of patients).
