Autoimmune Encephalitis After Herpes Simplex Virus Encephalitis
A recent study showed that about 25% of patients with herpes simplex encephalitis develop neurological symptoms three to six weeks after the infection, pointing toward an autoimmune process with different neurological and psychiatric symptoms. Anti-neuronal antibodies, such as anti-N-methyl-D-aspartate receptor antibodies, have been found in this post-viral autoimmune encephalitis presentation.

Treatable Causes of Rapidly Progressive Dementias
Many cases of rapidly progressive dementia are caused by prion diseases and have no effective treatments. But, with the greater awareness of the presentation for autoimmune encephalitis, these disorders make up an increasing percentage of presenting cases and can be aggressively and successfully treated. The STAM3P score helps to identify potentially treatable cases of this disorder.
