Patient: On February 17, the patient had symptoms of a cold and fever and was seen at a local hospital. During the visit the patient drank alcohol and developed swollen hands and feet and purple spots. Then he started to show abnormal behavior, babbling and mentioning the same thing over and over again, and memory loss. His appetite decreased significantly and his temper began to flare. At first, he was treated at Inner Mongolia Mental Health Center, but his condition worsened. The doctor suspected encephalitis and recommended the patient to go to Inner Mongolia Hospital for lumbar puncture examination, and the test results were critical. The doctor of Inner Mongolia Hospital initially diagnosed encephalitis, and then carried out nearly 15 days of treatment for encephalitis, but the effect was not obvious, and the patient kept saying he had a headache. The patient’s mental symptoms became more severe. During the treatment of encephalitis, the doctor analyzed that the encephalitis was not serious, and the EEG and CT were normal, but the patient’s symptoms just did not improve. The patient was slightly improved by the medication, but it was unstable, and sometimes he had headache symptoms. Now the patient is recuperating at home but relying on medication to maintain. I hope you can help us analyze what the patient’s illness is and what kind of tests we need to do to confirm the diagnosis. Thank you and I look forward to your reply. Guangzhou Brain Hospital Psychiatry Department Yang Mingzhe: The possibility of encephalitis is higher, EEG and lumbar puncture are of great significance, but it depends on the timing of the examination. Patient: Thank you very much for your reply I would also like to ask you: what is the most appropriate time for the examination? The patient has been recovering at home for two months, but there are still tantrums, which are controlled by psychotropic drugs. Is this a sequel to encephalitis? What should be the treatment? Should I treat this as schizophrenia or encephalitis? Finally, I would like to thank you again for your reply. Yang Mingzhe, Psychiatry Department, Guangzhou Brain Hospital: This problem is slightly complicated, you should seek professional medical consultation and analyze the specific situation. I don’t know the patient’s status, and giving advice may be misleading. I reckon the sequelae of encephalitis are likely. Patient: Thank you, doctor. Yang Mingzhe, Psychiatry Department, Guangzhou Brain Hospital: OK.
