People who suffer from stress or emotional instability during childhood or at any period in life may develop chronic fatigue syndrome (CFS), a severe health disorder, according to recent studies.
CFS is a complicated condition that causes a person to become so lethargic that he or she can't perform normal tasks. The condition is difficult to diagnose. It affects between 400,000 and 900,000 American adults.
AdvertisementChristine Heim from Centers for Disease Control and Prevention and Emory University, Atlanta, compared 43 individuals with CFS to 60 without CFS. Everyone underwent a medical examination and provided their medical history, and were interviewed to detect psychiatric disorders, according to Newswise wire.
In the final analysis, it was found individuals with CFS had higher overall trauma scores than those without CFS. Exposure to trauma increased the risk of CFS between three and eight times, depending on the type; emotional neglect and sexual abuse during childhood, the researchers said.
In the second study, Kenji Kato from Karolinska Institutet, Stockholm, Sweden, assessed 19,192 Swedish twins born between 1935 and 1958.
Kato found that individuals whose lives were stressful were 64 to 65 percent more likely to develop CFS.
