Rational anti-rage drug

Keppra aka levetiracetam is a seizure drug. I am not sure how these things are discovered but the target is some brain receptor with uncertain function; see link. Keppra has the unusual side effect of predisposing to rage; see link. This is not combativeness with confusion like someone drunk, but just short temperedness. A weird side effect.

Maybe the protein targeted by this drug (something called SV2A) is important for rage. Maybe the people with rage problems have some deficit in quantity or function of this, or in people who have rage problems for other reason (eg dementia) increased SV2A function might help with that. I propose that a drug could be designed to bind SV2A to do the reverse of keppra. One would expect such a drug in excess might also lower seizure threshhold which would not be good.

If this does not bring beanangel out of the woodwork nothing will.
