Our 48 year old daughter has been on depakote and lamictal for seizure control for over ten years. She is severely mentally handicapped and cannot tell us what is bothering her but she seems to be losing the ability to control her legs and at times simply cannot walk. I know from lurking on this forum that lamictal in particular can cause loss of leg control but her neuro doesn't seem to think that that is the cause. It's scaring us to death since she cannot crawl or walk any distance unless we hold her by the shoulders. The deteriation is not linear in that some days she walks fairly well yet may lose almost all control of her legs by the evening. Any ideas? She does have daily lennox gasteau type seizures.
