NewMexiKen was going to blog about this yesterday but I was too tired. From a report in the Los Angeles Times:
Chronic fatigue syndrome, often dismissed as the imaginings of depressed and whiny people, is caused by genetic mutations that impair the central nervous system’s ability to adapt to stressful situations, according to a major new study by the Centers for Disease Control and Prevention.
Small changes in many of the genes in the brain prevent the nervous system from rebounding from everyday stress and from less frequent, stronger pressures, eventually triggering a cascade of molecular responses that leave the patient severely debilitated, researchers reported Thursday in 14 separate papers in the journal Pharmacogenomics.
