Chronic Fatigue

What Is Chronic Fatigue?

Chronic fatigue is a state of pronounced exhaustion that persists for at least six months without an apparent cause.

Symptoms can be neurological, muscular, immunological, or psychiatric in nature.

It is estimated that this syndrome affects fewer than one in 200 people, and its cause remains mysterious to this day.

Chronic fatigue syndrome (CFS) is defined as a set of symptoms characterized by intense and nearly constant exhaustion that arises without an apparent cause or underlying pathology. The individual is so fatigued that they lack the energy to perform simple daily tasks such as getting out of bed in the morning, even after a good night’s sleep, grocery shopping, or even maintaining personal hygiene. In severe cases, this condition can significantly impact the individual’s social and professional life, and they may lose their autonomy.

This syndrome has also been referred to as neurasthenia, post-viral fatigue syndrome, chronic mononucleosis, yuppie flu, Lake Tahoe disease, or myalgic encephalomyelitis (ME). Chronic fatigue was recognized as a serious neurological disease by the WHO in 1992.


Chronic fatigue is characterized by:

  • Intense fatigue lasting for more than 6 months.
  • Malaise after physical exertion.
  • Non-restorative sleep.
  • And at least one of the following signs:
    • Impaired cognitive function, including executive and visuospatial functions, memory, attention, and social cognition.
    • Orthostatic intolerance, meaning intolerance to the upright position.

Additional manifestations can include sleep disturbances, heart rhythm issues, muscular pain, neurological symptoms, respiratory problems, ear-nose-throat issues, urinary-genital symptoms, and gastrointestinal problems.
