Are we any closer to finding a blood test or cure for Chronic Fatigue Syndrome than say a few years ago?
Not much advance in terms of a blood test.
In terms of a cure, I don't think there has been much progress either. Although there are a number of ME/CFS treatments that can often improve ME/CFS.
Treatments which have a track record of helping ME/CFS and are used by various ME/CFS doctors, or which have been shown effective in studies, include:
B12 methylcobalamin injections (or transdermal B12 oils)
Methylation protocol
Low-dose naltrexone
Oxymatrine (immunomodulator for enterovirus ME/CFS)
Inosine (good add-on immunomodulator with oxymatrine)
Epivir (for enterovirus ME/CFS)
Valcyte (for HHV-6 or cytomegalovirus ME/CFS)
Valtrex or Famvir (for EBV ME/CFS)
GcMAF injections (antiviral immunomodulator)
Tenofovir (antiviral immunomodulator)
Nexavir (porcine liver extract, an antiviral immunomodulator)
Ampligen (antiviral immunomodulator, but hard to get and expensive)
IVIG (expensive)
Interferon beta (antiviral immunomodulator, expensive and benefits usually do not last)
Piracetam (good supplement for brain fog)
Nimodipine (good drug for brain fog and brain blood flow)
Methylphenidate (stimulant drug for brain fog and fatigue)
Dichloroacetate (supplement for brain fog, fatigue and pain, boosts mitochondria)
Modafinil (stimulant drug for brain fog)
Moclobemide (dopamine-boosting drug for fatigue)
Pyridostigmine (reduces or eliminates PEM)
D-ribose (to speed up PEM recovery)
Dichloroacetate (improves fatigue and brain fog)
Probiotics and prebiotics (if there are gut issues)
Rifaximin (for IBS or gut dysbiosis)
