CHRONIC FATIGUE SYNDROME is a condition whose causes are still not fully understood. It can result from various causes that may have little similarity with each other, yet the symptoms that are observed may be similar.

CHRONIC FATIGUE SYNDROME : AN OVERVIEW

Chronic fatigue syndrome is a condition of persistent debilitating fatigue that produces severe distress apart from interfering with working as well as daily activities.
