What causes Limbic encephalitis ?
What causes limbic encephalitis? In many patients limbic encephalitis is a paraneoplastic syndrome, which is most commonly associated with small cell lung cancer (SCLC), breast cancer, testicular tumors, teratomas, Hodgkin's lymphoma, and thymomas.  Out of the various cancers linked to limbic encephalitis, the typically associated tumors are SCLC, which are present in about 40% of patients that have the paraneoplastic form of limbic encephalitis.  Seminoma are present in 25% of patients.  At a lower rate, nearly any other tumor may be associated.  Limbic encephalitis can also occur in the absence of cancer such as in the case of an viral infection and systemic autoimmune disorders.  The underlying cause of limbic encephalitis is probably an autoimmune reaction which is brought about by cancer, tumors, infections, or autoimmune disorders.
