2019-04-09 2020-01-03 Antibodies directed against the 65-kD isoform of GAD (GAD65) are encountered at high titers (≥20 nmol/L) in a variety of autoimmune neurologic disorders including stiff-person (Moersch-Woltman) syndrome, autoimmune cerebellitis, brain stem encephalitis, seizure disorders, and other myelopathies. Magnetic Resonance Imaging in a Case With GAD65-Positive Autoimmune Limbic Encephalitis Rachael Gardnera, Rajesh Rangaswamyb, Yen-Yi Peng a, c Abstract With the increased availability of laboratory tests, glutamic acid de-carboxylase (GAD) antibody-positive limbic encephalitis has become an emerging diagnosis. The myriad symptoms of limbic Autoimmune encephalitis is seen in a broad age range but most commonly affects young people. The annual incidence of encephalitis is up to 12.6 per 100,000 individuals [1, 6, 7], 20–30% of whom have an underlying autoimmune etiology [6, 7].One recent population-based study found the prevalence of autoimmune encephalitis as 13.7 per 1000,000 individuals, comparable to all infectious Antiglutamic acid decarboxylase 65 (GAD65) antibody-associated epilepsy. Glutamic acid decarboxylase (GAD) antibody-associated encephalitis causes both acute seizures and chronic epilepsy with predominantly temporal lobe onset. This condition is challenging in diagnosis and management, and the incidence of GAD antibody (Ab)-related epilepsy could GAD65-Associated Limbic Encephalitis One autoantibody associated with limbic encephalitis (LE) targets intracellular neuronal antigens (IAg) (GAD65 receptor) and three others target the neuronal surface antigens (SAg) (NMDA [N-methyl-D-aspartate) receptor, VGKC [voltage-gated potassium channel]-complex, and AMPA [α‐amino‐3‐hydroxy‐5‐methylisoxazole‐4‐propionic acid] receptor). The course of GAD 65 antibody‐associated encephalitis is longer than other autoimmune encephalitides.
