National Institute of Neurological Disorders and Stroke. For other people, recovery may take years. IVIG offers an important advantage of being unlikely to make an infectious encephalitis worse. While the exact mechanism of AIE is unknown, current literature suggests that autoimmune antibodies target synaptic proteins leading to widespread inflammation.[1].

They will include a constellation of neuropsychiatric symptoms, lab studies, neuroimaging, and EEG. Intracellular antibodies (those that are INSIDE the cell and involve aggressive T-cell responses targeting the neuronal brain cells) are mostly mediated by cytotoxic CD8+ T cells that cause functional and structural neuronal damage and this is why there is a likelihood that a response to immunotherapy is not seen in these patients. AIE commonly presents as new onset of memory loss, psychosis, altered mental status, or seizures, with the presentation taking place over a few weeks to three months. Classical fasciobrachial dystonic seizures. The first-line conventional treatments of autoimmune encephalitis consist of steroids, intravenous immunoglobulin (IVIG), plasma exchange .
