Patients with cerebral infarction become hoarse after the onset of the disease, mainly because of the damage to the central nervous system leading to dysarthria. The human body’s pronunciation is carried out by the fine control of the nervous system over the muscles of the throat. If cerebral infarction directly or indirectly causes the fine innervation function of the nervous system to the throat muscles to be impaired, dysarthria occurs, which will affect the tone and clarity of pronunciation, i.e., hoarse voice. If the cerebral infarction is mild or the infarcted area is not large, the symptoms of hoarseness may be gradually reduced or even completely disappeared by improving cerebral vascular circulation, nutritive nerves, rehabilitation training and other therapeutic methods. However, if the area of infarction is large, or the critical part of the infarction occurs, the symptoms of hoarseness will be difficult to return to normal. Hoarseness of voice in patients with cerebral infarction may also be related to other factors, such as problems with the vocal cords in the throat. It is recommended that the patient consult a doctor in time to clarify the cause and then treat the symptoms.
