Diagnosis of AE on clinical basis confirmed by pediatric study

Experts in the field of AE came together in 2016 to establish a set of clinical diagnostic criteria to be used early in the course of disease (Graus et al). This was developed so that patients might be diagnosed with suspected AE and treated promptly, while still awaiting test results or in areas where antibody …

From VGKC to LGI1 and Caspr2 encephalitis: The evolution of a disease entity over time

Science Direct has published an article by authors van Sonderen, M.W.J. Schreurs , P.W. Wirtz , P.A.E. Sillevis Smitt, and M.J. Titulaer that a wide variety of clinical syndromes has been associated with antibodies to voltage-gated potassium channels (VGKCs).

Lancet Neurology publishes paper on brain imaging and diagnosis of autoimmune encephalitis

It is often difficult to clinically diagnosis autoimmune encephalitis because patients’ symptoms can be so widely varied. In the Sept. 2016, issue of The Lancet Neurology, Francesc Graus and colleagues proposed an initial diagnostic work-up relying on conventional neurological evaluation and standard diagnostic tests such as MRI, CSF sampling, and EEG. This approach would enable clinicians to make …

Listing of known autoimmune encephalitis antibodies published by Perelman School of Medicine at the University of Pennsylvania

We get a lot of questions about known AE antibodies.  Identification of antibodies on a cellular level has led to a reclassification and renaming of many diseases. Note that many people who have AE are antibody negative, which most in the medical community agree is because all antibodies simply have not yet been discovered. The Center for Autoimmune Neurology …

The Lancet publishes first broadly accepted criteria for diagnosing autoimmune encephalitis

Today The Lancet released an important paper from Dr. Dalmau et al., providing the first broadly accepted criteria for diagnosing autoimmune encephalitis. Included in the paper are guidelines for diagnosing anti-body negative AE, a frustratingly difficult subset of AE cases to diagnose and thus treat. Many of the paper’s authors attended the International Symposium on Autoimmune …
