My Boyfriend Takes Medicine For Seizures From Strokes He Had

my boyfriend takes medicine for seizures from strokes he had and i beleive he is having mild seizures that he is not aware of. Staring into space, grinding his teeth, continuous swallowing due to excess saliva, sometimes almost choking on saliva and then drooling a bit. at the end, puts his head down and is tired. has no idea what happened. When I ask if he is ok, no answer.
