title: [Encephalitis due to measles].
abstract: OBJECTIVE
  We present seven cases of acute encephalitis following measles, which were diagnosed during the epidemic that occurred in Spain in 1986.
  
  
  METHODS
  We studied seven patients diagnosed of encephalitis due to measles. The diagnosis of measles was a made by the presence of a characteristic morbiliform rash and the detection of specific IgM antibodies. The diagnosis of encephalitis was based on the symptoms and the routine examinations of blood, CSF, EEG, CT, ophthalmic exploration and the study of the audiovisual evoked potentials.
  
  
  RESULTS
  The patients were between 5 and 9 years of age. None of them had been previously vaccinated for measles. The symptoms of encephalitis occurred 1 to 12 days after the appearance of the rash and the most frequent symptoms were drowsiness and vomiting. All of the patients had EEG abnormalities that returned to normal 1 to 18 months after the diagnosis. One patient presented CT abnormalities. CSF examination revealed an increase of the cell count in one case. The ophthalmic exploration was normal except in one of the patients which had optic neuritis. There were no abnormalities in the audiovisual evoked potentials. All of the cases showed good evolution. Five years later, all of the patients have had a normal development.
  
  
  CONCLUSIONS
  The correct vaccination of measles can eradicate this disease.
