Cerebral infarction generally does not directly cause sudden deafness, but it can cause speech and hearing comprehension disorders.
Cerebral infarction is a clinical syndrome that affects neurological function due to ischemic and hypoxic necrosis of brain tissue. Depending on the location of the infarcted blood vessel, the clinical manifestations vary, but generally does not directly cause sudden deafness.
When the infarction is in the middle cerebral artery, complete aphasia or Wernicke’s aphasia (also known as auditory aphasia) occurs, which is characterized by severe hearing comprehension disorders, i.e., the patient is unable to understand his/her own speech or the speech of other people even though he/she has normal hearing.
Seek medical attention as soon as possible after the onset of symptoms of cerebral infarction. Prompt treatment is likely to improve the prognosis.
