Fatigue describes a state of tiredness (which is not sleepiness), exhaustion[1] or loss of energy.[2][3]

Fatigue (in the medical sense) is sometimes associated with medical conditions including autoimmune disease, organ failure, chronic pain conditions, mood disorders, heart disease, infectious diseases, and post-infectious-disease states.[4] However fatigue is complex and in up to a third of primary care cases no medical or psychiatric diagnosis is found.[5][6][7]

Fatigue (in the general usage sense of normal tiredness) often follows prolonged physical or mental activity. Physical fatigue results from muscle fatigue brought about by intense physical activity.[8][9][10] Mental fatigue results from prolonged periods of cognitive activity which impairs cognitive ability, can manifest as sleepiness, lethargy, or directed attention fatigue,[11] and can also impair physical performance.[12]
