Burn-out syndrome
It is rare to find information on burn-out (or exhaustion syndrome) as a medical condition in text books. There is no standard definition of it. Since it is not possible to identify it using imaging techniques or laboratory testing, it has been assumed that the condition does not actually exist as such. At the same time, it puts a tremendous burden on the sufferer. He or she feels burnt out and has physical and mental symptoms which include tiredness, physical weakness, poor concentration, difficulty sleeping and listlessness.
Burn-out syndrome is a physical and mental reaction to usually persistent or serious stress which has exhausted the individual's capacity to regulate the body. The symptoms generally develop gradually over an extended period of time, and this is why they are often not noticed until they have reached an advanced stage.
