There are many causes of neurological deafness, which may be due to drug poisoning, meningitis, trauma, etc. Some of them can be recovered, while some cannot be completely recovered. 1. Drug poisoning: If it is caused by drug poisoning, such as aminoglycoside antibiotic drugs, it will easily lead to toxic damage to the nervous system, which will lead to damage to the auditory nerve, resulting in neurological deafness, if the drug is stopped early and cooperate with the doctor’s treatment, it is possible to recover, but if the damage to the auditory nerve is serious, it can’t be completely recovered. 2. Meningitis: For neurodeafness caused by meningitis, most of them are severe deafness, which is not easy to recover. 3. Trauma: If neurodeafness is caused by trauma, for example, head trauma caused by hematoma compression, early and early treatment, it is possible to recover, but if the damage involves the auditory nerve, even through surgical treatment may not be able to recover completely. Once nerve deafness occurs, we should go to the hospital as soon as possible to clarify the cause and extent of the disease, and cooperate with the doctor to take active treatment.
