Sudden unexpected death in epilepsy (SUDEP) is the major cause of premature death in epilepsy patients, particularly those with refractory epilepsy. Sudden unexpected death in epilepsy is thought to be related to peri-ictal cardiac dysfunction, respiratory depression, and autonomic dysfunction, albeit the exact etiology is unknown. Sudden unexpected...

Most seizures in critical ill patients are non-convulsive, and some patients may develop non-convulsive status epilepticus (NCSE), a state of continuous or repetitive seizures without convulsions. With the growing use of continuous electroencephalogram (EEG) monitoring in neuro-intensive care units, non-convulsive seizure (NCS) and NCSE are increasingly...

18F-fluoro-deoxyglucose position emission tomography (18F-FDG-PET) has been proven as a sensitive and reliable tool for diagnosis of autoimmune encephalitis (AE). More attention was paid to this kind of imaging because of the shortage of MRI, EEG, and CSF findings. FDG-PET has been assessed in a few small studies and case reports showing apparent abnormalities...
