| Summary: | <p><strong>Objective</strong> To study the clinical and laboratory features and diagnosis of the patient with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. <strong>Methods</strong> The data of clinical features, laboratory findings, and radiological manifestations of 3 patients with anti-NMDAR encephalitis were reviewed and analyzed. <strong>Results</strong> Of the 3 patients, 2 were male and one was female. The age was from 33 to 34 years (33.30 years on average). Main symptoms included headache in 2 cases, psychiatric symptoms and speech disorder in 3 cases, different levels of movement disorder in one case and hallucinations in one case. The results of MRI examination revealed gyri swelling, abnormal signal and demyelination of temporal lobe. The EEG showed focal or diffuse slow waves. All cases were confirmed to have the disease by detection of anti-NMDAR antibodies. Both the white blood cell count (3 cases) and protein quantification (2 cases) elevated. No tumor was detected in any of the patients. All patients were coued after receiving immunotherapy with methylprednisolone and human immunoglobulin. <strong>Conclusions</strong> Anti-NMDAR encephalitis is a severe but treatable disorder. The syndrome is highly recognizable clinically and can be confirmed with the demonstration of anti-NMDAR antibodies. Timely diagnosis and treatment may yield a favorable prognosis.</p><p> </p><p>doi: 10.3969/j.issn.1672-6731.2014.07.005</p>
