RT Journal Article SR Electronic T1 Case report of the treatment and experience of mental disorders due to chronic viral encephalitis JF General Psychiatry JO Gen Psych FD BMJ Publishing Group Ltd SP e100340 DO 10.1136/gpsych-2020-100340 VO 34 IS 1 A1 Mingming Zheng A1 Ran Bi A1 Yezhe Lin A1 Cuizhen Zhu A1 Daomin Zhu YR 2021 UL http://gpsych.bmj.com/content/34/1/e100340.abstract AB Viral encephalitis is a common clinical condition. Its clinical manifestations are variable and include neurological symptoms and psychiatric abnormalities, which makes clinical diagnosis and treatment difficult. To date, there are only a few reported cases on mental symptoms of chronic viral encephalitis. We present a case of a 16-year-old male patient who was previously hospitalised and diagnosed with schizophrenia and treated with aripiprazole 15 mg/day but failed to respond. The patient was then given antiviral therapy and recovered after 2 weeks. Clinicians should be aware of the possbility that chronic mental disorders could be caused by viral encephalitis. In the future, diagnosis of chronic functional mental disorders should include viral encephalitis in the differential diagnosis.
