Aphasia after open-heart surgery is a common complication. Depending on the type, aphasia can be divided into named aphasia, motor aphasia, sensory aphasia, and mixed aphasia. Depending on the type of aphasia, rehabilitation treatment options are different. Recovery is generally slow, and partial speech function may be restored through treatment in a regular rehabilitation hospital. There are some oral medications that can help restore speech function and achieve simple communication, but the effect is less precise. To sum up, it is still recommended to go to a regular rehabilitation hospital or rehabilitation center for speech function training to improve the quality of survival.
