Stroke can result in sequelae such as deviation of the mouth, slurred speech, hemiplegia, numbness of extremities, coughing when drinking water, hoarseness, and difficulty swallowing. If the stroke affects a smaller area or is not located in a critical area, recovery tends to be better. However, if the infarct is large or occurs in a critical area like the brainstem, sequelae may persist, with partial function recovery possible within about three to six months.
