I can only speak for myself, but my mum (54) started having fits about 9 months ago, after having AD for about 1 1/2 years. Obviously we were concerned, but the home's GP said that with AD patients, often they can suffer from small seizures or mini strokes. She is now on anti-convulsent medication and that seems to have sorted things out. Having read other posts on the forum about fits, other people seem to relate to this problem and say it is not uncommon. Hope this helps.
My husband takes Myoclonic jerks they were strong jerks. One the day of his first seizure he took 2 very strong jerks just before the seizure. I've been told they don't know when and if he will take another but there is a high possibility when the Dementia progresses. The seizure ended him in hospital as it took him all day to come around from it. He has deteriorated after the seizure. He was on medication for the jerks so its be doubled now. I've been told if he takes another he will be back in hospital. Looks like its part of the slippery slope.
