Hi There, Twenty minutes could certainly be a timeframe for seizure activity - Complex partial seizures can impair consciousness and involve automatic movements and lake of responsiveness. She may be on a new medication that lowers seizure threshold or perhaps some small infarct has created a node? I would also DEFG (don t ever forget glucose) hypoglycemia can present with agitation and altered mental state. Other possibility is a hypotensive episode due to carcinoid - is she flushed? Well, these are just a few thoughts... Hope you get to the bottom of it.
