the important thing to know is does he had a documented intracranial infection ? meaning : did they did Lumber puncture ? and what was the results of the analysis and culture of the cerebrospinal fluid?
early convulsions in meningitis usually suggest a good prognosis unless it was a devastating
bacterial meningitis which can affect the vision, hearing and can cause mental retardation as well , and sometimes is associated with convulsions .
EEG can be normal in 30 % of patients who has convulsions , and it doesn't exclude it .
the most important next step is doing
MRI scan of the brain , to exclude congenital malformation , inflammatory changes following meningitis.
a video showing these Jerks is very important in diagnosis , because some infants can exhibit Benin
myoclonus Jerks during sleep and is considered normal .
so the following is needed :
- brain MRI
- video documenting the Jerks.
- if a documented meningitis was there , then should do hearing test ( aquestic emission)
I hope this was helpful
