First I am so sorry for your loss. I am not aware of any statistics re suicidality and the AEDs. Each med comes with it's own adverse reactions discovered during trials. Vimpat has been used in the UK much longer than in the US and is too new for that info to be known I think. I do know with the AEDs and with other meds like antidepressants, it is always suggested to watch for signs of suicidality because no one really knows how a med will affect a person. Those around the patient will reconize differences in behavior and emotions first I would think; changes in sleep patterns, appetite, energy, outlook such as apathy, no desire etc. Also you mentioned several meds that she was on. Lots of meds and too much can cause seizures too. Not only does each med have its own effects The combination of the drugs has concomitant effects as well. I wish she had gone to an epileptologist at a Comprehensive Center since she had had surgery and was still having seizures on so many meds. Again I am sorry for your loss. Tattoo
