ABSTRACT
Objective:
To investigate the clinical features of patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis misdiagnosed as mental disorder, improve the early diagnosis rate and reduce misdiagnosis.Methods:
The clinical data of patients with anti-NMDA receptor encephalitis diagnosed at the First Affiliated Hospital of Zhengzhou University from 2012 to 2018 were collected. Patients misdiagnosed as mental disorders were screened out. Their psychiatric symptom characteristics, disease course characteristics, imaging and laboratory findings, treatment and prognosis were retrospectively analyzed.Results:
A total of 121 cases of anti-NMDA receptor encephalitis were collected, and 43 cases of mental disorders were screened out. Sixteen of the 43 patients (37.2%) had prodromal symptoms, and all the patients had psychiatric behavioral abnormalities (100%), including 32 cases (74.4%) of seizures, 13 cases (30.2%) of decreased level of consciousness, 21 cases (48.8%) of involuntary movements, 15 cases (34.9%) of decreased memory, 8 cases (18.6%) of speech dysfunction, and 8 cases (18.6%) of other neurological symptoms (central hyperventilation, autonomic dysfunction). Memory loss was observed in 15 cases (34.9%), speech dysfunction in 8 cases (18.6%), other neurological symptoms (central hypoventilation, autonomic dysfunction) in 8 cases (18.6%), and various symptoms may appear simultaneously or successively in the same patient. Thirty-eight cases had complete resolution of symptoms or only minor physical impairment, and 5 cases had recurrent admissions with mental abnormalities and seizures. The recurrence rate accounted for 11.6% (5/43).Conclusions:
The clinical manifestations of anti-NMDA receptor encephalitis are complex and varied. Most of them have mental behavior abnormalities as the first symptom, which is easily misdiagnosed as mental disorder and delayed treatment will lead to prolonged disease course and poor prognosis.
