Experience of Keppra - yes, the rage! We couldn’t cope with the rage. Nobody told us about vitamin B.
Ime of DD, many of the drugs cause some sedation. The consultant neurologist told us, that epilepsy is really an over-excitable brain. The drug’s function must be then, to calm it down. Unfortunately, we don’t seem to be able to select which part of the brain’s functioning is calmed down - it often seems to include some tiredness/sleepiness/lack of alertness, whatever you want to call it.
Sodium valproate can increase appetite and aggression, among other side effects (and iirc cognitive slowing).
Clobazam can cause sedation and aggression. Works very well on seizures though, but it is prescribed as an adjunct, not a first line drug.
Lamotrigine made DD veer between hyper or depressed.
Zonisamide slows down thinking, and can have a dreadful effect on language.
You pay your money and make your choice of the side effects! (Well, they will try the first line drugs for a couple of seizures; you won’t get a choice of the expensive branded versions of drugs like zonisamide, rufinamide, lacosamide, etc at this stage)
Has anybody told you the importance of a routine of three good meals a day; good sleep, exercise, activity (rather than boredom or too much screens) and reducing stress if possible? None of these are a non drug alternative way to control epilepsy - if a drug has been prescribed, it’s needed. However, hunger, tiredness, inactivity, stress, pain, etc can be triggers for seizures and you might as well try to reduce the number of provoked seizures - you need to keep a seizure diary, to try to identify triggers.
