Living with Limbic encephalitis

A group of autoimmune brain conditions that cause inflammation in memory-related brain areas.

Understanding Limbic encephalitis

Limbic encephalitis is a group of autoimmune conditions marked by inflammation of the limbic system and other parts of the brain.

The main sign is severe trouble with short-term memory. Symptoms can also include confusion, psychiatric symptoms, and seizures. They usually develop over weeks or months, but may develop over a few days. It is often linked to an underlying tumor, but some cases never have one found.
