title: Central periodic breathing during sleep in acute ischemic stroke.
abstract: OBJECTIVE
  It has been suggested that central periodic breathing during sleep (CPBS) may develop in unilateral supratentorial stroke without cardiopulmonary disease and disturbed consciousness. Not many data existed about such patients.
  
  
  METHODS
  Of 31 patients with first-ever stroke, we report 3 patients with CPBS in the absence of cardiopulmonary and vigilance disturbances. Patient assessments included polysomnography, MRI and echocardiography. Nocturnal breathing was reassessed after 1 to 3 months.
  
  
  RESULTS
  The patients had ischemic strokes in the left cingulate cortex, left insula and right paramedian thalamus. They were fully conscious when submitted to sleep recordings and lacked overt cardiovascular dysfunctions (ejection fractions=67%, 48%, 65%). CPBS was present during 18% to 24% of sleep. In all patients, breathing improved during stroke recovery.
  
  
  CONCLUSIONS
  CPBS may be present in strokes involving autonomic (insula) and volitional (cingulate cortex, thalamus) respiratory networks. As such, CPBS partly resolves within weeks.
