is increasingly recognized
Many cases of encephalopathy previously considered infectious are now recognized to have an autoimmune cause. In fact, based on a recent Mayo Clinic study, autoimmune encephalitis was found to be as common as infectious encephalitis.1

When to consider testing
Consider autoimmune testing for patients presenting with new-onset encephalopathy (non-infectious or metabolic) and one or more of the following:
Our autoimmune encephalopathy evaluation is part of an evolving approach to testing for autoimmune neurological disorders using phenotypic-specific evaluations that include multiple antibodies known for their disease association.
Beyond the Test Result
Greg Widseth was suddenly hit by a rare disease that prompted his immune system to attack his brain cells, resulting in as many as 60 seizures a day. Special blood and spinal fluid tests developed by Mayo Clinic Laboratories confirmed that Widseth had antibodies known to target certain brain cells.
For people with encephalitis, rapid treatment of their acute brain inflammation is critical for avoiding devastating physical and cognitive deficits. But appropriate treatment requires identifying the culprit causing the symptoms.
Andrew McKeon, M.B., B.Ch., M.D., gives an overview of the autoimmune encephalopathy evaluations. He focuses on when the tests should be ordered, how this testing improves upon previous approaches, and what clinical action the results enable.
