Many of the antiseizure I'm aware of are described as having the potential for behavior altering side-effects. I am curious about this.
- Is there something about the chemistry of the brain that frequently makes anticonvulsants also psychoactive? Does it have to be this way?
- Maybe the anticonvulsant drug profiles are like this because much more money is invested in R&D for psychoactive drugs used in psychology than is invested in R&D for epilepsy drugs. And, during the R&D process the anticonvulsant property of a drug is discovered as being the side effect of the drugs whose main property is psychoactivity. And this might be why the anticonvulsants being sold are psychoactive?
Viagra was discovered during R&D into high blood pressure. Viagra does lower high blood pressure. Viagra also has a side effect. People take Viagra for the side effect.
So, might it be like:
During R&D into psychoactive drugs, Zonisamide was discovered to have the side effect of elevativing the seizure threshold. Zonisamide is psychoactive. Zonisamide also elevates the seizure threshold as a side effect. People take Zonisamide for the side effect?
Is it understood why anti-epileptic drugs are always mood altering? Is it chemical? a product of the R&D cycle? a simple correlation that a person with the disease might be more emotional?
