BACKGROUND: Patterns observed with electroencephalography (EEG) for @entity1 who have @entity198 are usually known as generalized nonspecific @entity75 . The aim of this study was to investigate the presence of a special EEG pattern for @entity1 with @entity198 and to explore features related to this special and uncommon pattern. METHODS: EEG monitoring was performed for every @entity1 aged >15 years with @entity198 who was hospitalized between December 2011 and March 2014. Clinical characteristics and EEG recordings were collected and evaluated. RESULTS: Fifty-two @entity1 with @entity198 were enrolled in our study with a 2-h median EEG recording time, and extreme beta brushes (EBBs) occurred in 17 @entity1 (32.7%). Its presence was not significant regarding gender, age, @entity146 medication use, EEG rhythmic disorganization (P > 0.05). Nevertheless, among the @entity1 with EBBs, nine @entity1 (52.9%) had @entity302 that had a significant detection rate (P < 0.05); moreover, the cerebrospinal fluid (CSF) or serum of 15 @entity1 (88.2%) with EBBs was positive for antibodies (P < 0.05). Four @entity1 (23.5%) who had EBB had corresponding regional distributions on neuroimaging scans. The EBBs completely correlated with the regional distributions of spike discharges for four @entity1 . CONCLUSION: EBB is a special EEG pattern for @entity1 with @entity198 , especially those with @entity302 or who have antibody-positive CSF/serum, and should be considered in clinical practice.
