Chronic fatigue syndrome
Chronic fatigue syndrome is generally characterized by extreme fatigue that lasts for at least six months, cannot be fully explained by an underlying medical condition, worsens with physical or mental activity, and does not improve with rest. Symptoms are not homogeneous, and almost every patient has a unique and fluctuating constellation of symptoms. It is also known as myalgic encephalomyelitis or chronic fatigue immune dysfunction syndrome.
