A question about a health problem i had.

Patient: 3 years ago my mouth crooked in one night.i couldn’t speak clearly.i was 35.i thought it was a stroke, but my parents took me to a psychiatric clinic where i stayed for 1 month and a half and i recovered.during that time i was taking 10 pills per day.now i stopped medication and i feel ok.but i always fear it may happen again…is it possible?was it a neurological incident or else?i thank you in advance.
