What are the main symptoms?
Chronic fatigue of more than 6 months of evolution is characterized by:
· Myalgias
· Muscle weakness
· Post-extertional fatigue
· Impaired short-term memory and concentration
· Sleep disorder
· Headache
· Slight fever
· Odynophagia (painful swallowing)
· Arthralgias
· Dizziness and vertigo
What are its causes?
Based on a genetic predisposition, there would be a triggering agent (usually a viral infection) that would launch a series of immunological changes with the release of substances called “cytokines” which would be the cause of the symptoms of chronic fatigue.
