title: Hypothalamic abnormalities and Parkinsonism associated with H1N1 influenza infection.
abstract: OBJECTIVE
  To describe a case of a young adult with severe H1N1 influenza illness associated with hypothalamic abnormalities and post-influenza parkinsonism.
  
  
  METHODS
  Case report.
  
  
  METHODS
  A 22-year-old woman with H1N1 influenza infection developed encephalopathy followed by diverse hypothalamic dysfunction manifestations, sleeplessness, and persistent parkinsonian features.
  
  
  RESULTS
  CSF analysis, brain imaging and EEG ruled out hypoxic brain injury or other illnesses.
  
  
  CONCLUSIONS
  A number of viruses have been associated with both acute and chronic parkinsonism. A link between parkinsonism and influenza viruses is somewhat controversial. This is the first reported case of parkinsonism following an H1N1 influenza infection.
