What is Limbic Encephalitis?

Limbic encephalitis is a rare brain inflammation affecting memory- and emotion-related regions of the brain (hippocampus, amygdala, cingulate cortex). It can be autoimmune or paraneoplastic (cancer-associated).

Acute or subacute onset of short-term memory loss, behavioral changes, psychiatric symptoms, and seizures is typical. Antibodies (such as anti-Hu, anti-Ma2, LGI1, GABA-B) may be directed against specific antigens.

Significant improvement is achieved in some patients with early diagnosis and appropriate immunomodulatory therapy. The underlying cancer should be sought in paraneoplastic forms.
