The question of how long encephalitis can be cured depends on the severity of the encephalitis. In general, patients with mild viral encephalitis can be cured after 4-6 weeks of treatment. In the case of severe viral encephalitis, there will be some sequelae and treatment will take longer, leaving behind some cognitive impairment and personality changes. In addition, for autoimmune encephalitis, the treatment will take longer for heavy patients and will also leave sequelae. In mild encephalitis, after 1-2 months of treatment, the patient’s symptoms can be significantly improved and sometimes even cured. However, encephalitis, especially autoimmune encephalitis, is prone to recurrence, and treatment will take longer to last, with hormones and immunosuppressants being taken for 1-2 years even after discharge from the hospital. Be sure to take your medications under the guidance of your doctor and never stop taking them at random.
