A new episode of "Discussions with the Directors" is available on the topic of paraneoplastic testing - when is it appropriate and what is the way ahead. Listen Now!
In this month’s “Virtual Lecture,” Andrew McKeon, M.B., B.Ch., M.D., highlights the rapidly evolving field of autoimmune neurology. The importance of a timely and accurate diagnosis of autoimmune neurological disorders cannot be understated, so it is important that neurologists all understand the patient presentation as well as available testing and treatment options.
This “Specialty Testing” webinar will address the clinical presentations, evaluation (including diagnostic antibody testing), and treatment of autoimmune pediatric CNS disorders, including encephalitides and myelopathies.

This "Specialty Testing" webinar will discuss Cerebrospinal fluid (CSF), which has been used in research on Alzheimer's disease for decades. Only recently, have platforms been developed to standardize measurements across laboratories.
Currently the diagnosis of probable Alzheimer disease (AD) is made based on clinical symptoms, largely by the exclusion of other causes of dementia, with postmortem evidence of AD pathology required to confirm the diagnosis. Two common neuropathologic features found in the brains of patients with AD are the presence of plaques composed of beta-amyloid (Abeta) peptides and intracellular neurofibrillary tangles containing hyperphosphorylated Tau (tubulin-associated unit) proteins.
Divyanshu Dubey, M.B.B.S. gives an overview of this test available through Mayo Clinic Laboratories. He discusses when this testing should be ordered, how this testing compares to other testing approaches, and what clinical action can be taken due to the results of this testing.
Autoimmune encephalitis and myelitis is increasingly recognized as a cause of CNS disease in children and teens. Andrew McKeon, M.B., B.Ch., M.D, gives an overview of this test available through Mayo Clinic Laboratories. He discusses when this testing should be ordered, how this testing compares to other testing approaches, and what clinical action can be taken due to the results of this testing.
In this month’s “Hot Topic,” Divyanshu Dubey, M.B.B.S., discusses how patients with encephalopathy and/or epilepsy of unknown etiology may have an autoimmune or paraneoplastic cause.

This “Specialty Testing” webinar will describe the clinical, radiologic, and serologic characteristics of autoimmune myelopathies and their mimics.
Using advanced technology, scientists at Chan Zuckerberg (CZ) Biohub, Mayo Clinic and University of California, San Francisco (UCSF), have discovered an autoimmune disease that appears to affect men with testicular cancer.
Mayo Clinic Laboratories is the only laboratory in the world to offer testing for a novel form of autoimmune meningoencephalomyelitis. Known as autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy, the condition was identified by Mayo Clinic in 2016. The GFAP antibody test is offered as part of Mayo Clinic Laboratories’ encephalitis and myelopathy evaluations.
Patients with autoimmune myelopathy present with subacute onset and rapid progression of spinal cord symptoms (weakness, gait difficulties, loss of sensation, neuropathic pain, and bowel and bladder dysfunction). Autoimmune myelopathy evaluation of serum and spinal fluid can assist in the diagnosis and aid distinction from other causes of myelopathy (multiple sclerosis, sarcoidosis, and vascular disease). Early diagnosis may assist in diagnosis of occult cancer, prompt initiation of immune therapies, or both.
Antibodies to aquaporin-4 and myelin oligodendrocyte glycoprotein (MOG) are recently described biomarkers seen in a subset of atypical optic neuritis which have revolutionized our understanding of the condition. In this “Hot Topic,” my colleague, Dr. John Chen, will review these advances and how they impact the clinical care of our patients with optic neuritis.
