I am a 52 year old author with a cavernous angioma of the right temporal lobe, slightly overlapping the parietal lobe. I was diagnosed in 2007, even though I went my whole life having what we thought were low blood sugar fits. I take 2,500mg Keppra every day and still have visual aura's, olfactory aura's and absence seizures. My memory is horrible and I am a very nervous and emotional sort of person.
