AB  - Fatigue  is  one  of  the  most  common  symptoms  in  clinical  medicine.  It  is  a  prominent  manifestation  of  a  number  of  systemic,  neurologic,  and  psychiatric  syndromes,  although  a  precise  cause  will  not  be  identified  in  a  substantial  minority  of  patients.  Fatigue  refers  to  the  subjective  human  experience  of  physical  and  mental  weariness,  sluggishness,  low  energy,  and  exhaustion.  In  the  context  of  clinical  medicine,  fatigue  is  most  typically  and  practically  defined  as  difficulty  initiating  or  maintaining  voluntary  mental  or  physical  activity.  Nearly  everyone  who  has  ever  been  ill  with  a  self-limited  infection  has  experienced  this  near-universal  symptom,  and  fatigue  is  usually  brought  to  medical  attention  only  when  it  is  either  of  unclear  cause,  fails  to  remit,  or  the  severity  is  out  of  proportion  with  what  would  be  expected  for  the  associated  trigger.
