Autoimmune encephalitis

How is autoimmune encephalitis diagnosed?

Diagnosis of autoimmune encephalitis can be made when all three of the following criteria have been met:

1. Subacute onset (rapid progression of less than 3 months) of working memory deficits (short-term memory loss), altered mental status, or psychiatric symptoms

2. At least one of the following:

• New focal CNS findings
• Seizures not explained by a previously known seizure disorder
• CSF pleocytosis (white blood cell count of more than five cells per mm3)
• MRI features suggestive of encephalitis

3. Reasonable exclusion of alternative causes

A team of leading autoimmune encephalitis researchers have established diagnostic criteria for these conditions. View the full position paper, entitled A Clinical Approach to Diagnosis of Autoimmune Encephalitis.
