Brains of People With Chronic Fatigue Syndrome Offer Clues About Disorder - New York Times: Well (2014) is one of many ME/CFS articles by David Tuller.[1]

The images document neuroinflammation which causes many neurological symptoms experienced by patients.

Plainly seen is the result of neuroinflammation's impact on the brain.

Brain imaging studies mentioned in article[edit | edit source]

  • 2014, A Japanese PET scan study looked at neuroinflammation in 9 patients with ME/CFS and 10 controls. They measured a protein expressed by activated microglia, and found that values in the cingulate cortex, hippocampus, amygdala, thalamus, midbrain, and pons were 45%–199% higher in ME/CFS patients than in healthy controls. The values in the amygdala, thalamus, and midbrain positively correlated with cognitive impairment score, the values in the cingulate cortex and thalamus positively correlated with pain score, and the value in the hippocampus positively correlated with depression score.[4][1]

Myalgic encephalomyelitis[edit | edit source]

Myalgic encephalomyelitis (ME) was the original name for chronic fatigue syndrome (CFS); the names are often used interchangeably or with the acronym ME/CFS.[5] The name Myalgic Encephalomyelitis was coined by the Lancet journal following the 1955 Royal Free Hospital outbreak, [6] although it is often wrongly attributed to Melvin Ramsay.[7][8][9] and is a portmanteau of several of the key signs and symptoms of the disease: myalgic (muscle pain), encephalo (brain), myel (spinal cord), itis (inflammation).[10] The central nervous system (brain and spinal cord) are inflamed.[10]

  • Myalgic adj. - of or relating to myalgia. (muscle pain).[11]

Criteria defining ME, CFS, and ME/CFS[edit | edit source]

Patients that meet the International Consensus Criteria (ICC) defining ME are usually more severely impaired than patients that meet the Canadian Consensus Criteria (CCC) defining ME/CFS, or the minimum core symptoms needed to diagnose patients with Systemic Exertion Intolerance Disease (SEID); also an ME/CFS criterion. Researchers believe all patients meeting these criterion, including Fukuda criteria (with post-exertional malaise "option") defining CFS, are experiencing brain inflammation.[15][16]
