Brain tumor/seizures

  About 4 1/2 yrs ago I had been diagnosed with menigitis (meningitis). At that time they  noticed
  that I had a abnormality which was later diagnosed as a low-grade glioma.
  In the past 4 1/2 years I have had numerous MRIs and CTs and a steriotatic
  cranionomy.  I have severe daily H/As and have recently been diagnosed as
  having ocipital neuroliga.  Next week I will be having a cryo??? done, get the
  nerves frozen.  My question to you, however, is that recently I have been having
  these twitches, or full body jerks, mostly at night but sometimes during the day.
  I have had an EEG done, the diagnosis was that I had a tendency for seizures.
  Is there any relationship to the possible seizures(twitching) and the growth
  of the tumor.  Most importantly should I worry?  I have taken antiseizure
  meds in the past, but I am not taking any now.
  Thank you in advance for your response.
  
=======================================
I think there is unlikely to be a relationship, when whole body jerks
( myoclonic jerks) are associated with seizures they are part of a generalized epilepsy tendancy, this may show as spkies and slow waves on the EEG.
Brain tumors on the other hand cause the other type of epilepsy, focal epilepsy, in which the seizure origionates in one specific part of the brain, this would not cause generalized whole body jerks.
The answer really depends on what type of epileptic tendancy your EEG showed, if it showed changes related to the glioma then there is probably no connection, if it showed changes consistent with a generalized epilepsy then there is more likely to be a connection.
I suggest that you ask the person who performed the EEG this question and this should put your mind at rest.
