AB  - Sleep  comprises  roughly  one-third  of  an  adult’s  life.  It  is  an  active  physiological  process  with  wide  effects  on  health.  Poor/insufficient  sleep  has  the  potential  to  aggravate  any  disease  and  many  diseases  impact  sleep.  Therefore,  an  understanding  of  sleep  and  sleep  disorders  is  essential  for  the  practice  of  neuropsychiatry.  Sleep  disorders  epitomize  neuropsychiatry,  capturing  the  overlap  between  altered  brain  networks,  behavior,  and  cognition.  Sleep  deprivation  impairs  almost  all  cognitive  functions,  and  evidence  has  rapidly  accumulated  implicating  amount  and  quality  of  sleep  in  disturbances  of  memory  processing  and  consolidation.  Furthermore,  sleep  disorders  contribute  to  the  morbidity  of  both  psychiatric  and  neurological  disease.  The  likelihood  of  having  sleep  problems  increases  with  the  number  of  psychiatric  diagnoses,1  and  parasomnias  are  more  common  in  psychiatric  populations.2  Sleep  disturbance  is  now  a  well-recognized  common  consequence  of  traumatic  brain  injury  (TBI)  across  all  levels  of  TBI  severity,3  and  sleep  disruption  is  also  prevalent  in  neurodegenerative  disorders.4  Sleep  disorders  (e.g.,  obstructive  sleep  apnea  [OSA],  REM  behavior  disorder  [RBD],  other  parasomnias)  should  be  carefully  considered  in  patients  with  a  variety  of  cognitive  and  behavioral  presenting  complaints.  This  chapter  will  review  the  basics  of  sleep  physiology,  our  present  understanding  of  the  purpose  of  sleep,  and  briefly  review  sleep  disorders.
