Why does topamax (topiramate) cause memory problems& fatiguing is my dose high 25mg 2x a day? Can it cause permanent problems? Is it safe?

Yes it is safe. Topamax (topiramate) can cause fatigue early stage of taking it and may go away after few days, same goes for memory problems. If the side effects persist, you should discuss with your doctor and he/she may change your med or reduce the dose. It does not cause permanent problems with long term use.
Due to actions. Topamax (topiramate) blocks a glutamate pathway in the temporal lobe important for short term memory, and in fact, is dosage dependent, and if you are experiencing side effects at such a low dose, unlikely that you will do well if dose pushed into therapy range. Talk to your doctor. Yes, indeed reversible and safe, but may not be best drug for you!

How common are side effects like memory loss and other neuro problems in Topamax (topiramate)? How severe are they? Are they reversible?

What should I do about my husband's mood swings, short term memory loss from being on topiramate and having sleep apnea and grand mall seizures?

Mood swings. Have reevaluated by your neurologist who may want your husband sen by a psychiatrist.
Very complicated. Phenobarbital can worsen sleep apnea. Topiramate and Phenobarbital and sleep apnea can all affect memory loss. Keppra, (levetiracetam) topiramate, and phenobarbital, do not prevent mood swings. Keppra, (levetiracetam) in fact, could cause profound suicidal depression with and without hallucinations. Basically, it sounds like your husband's care is being managed by a neurologist and you need to get a psychiatrist involved and also a sleep medicine specialist. Best wishes.

Topamax (topiramate) substitute for weekly migraines w/no weight gain&memory loss side effects? Tylenol, NSAIDs&neurontin dont work. On trileptal, klon, &wellbutrin now

Weekly migraine. Most people would not take a medicine every day to prevent a migraine that occurs once per week. Unless that migraine lasts several days. Substitutes for topamax (topiramate) could be propranolol, magnesium, or valproate perhaps. Normally wellbutrin and propranolol are not used together, in case the mood worsens. Why are you using trileptal? Your side effects may occur due to medicine interactions.
