CNTNAP2 and dementia: A recent study demonstrates that 16-38% of patients with AIE, especially when associated with anti-NMDAR-IgG, anti-LGI-1-IgG, anti- gamma aminobutyric acid-B receptor-IgG (GABABR-IgG) and anti-Contactin-Associated Protein-Like 2 (Caspr2) auto-Abs, might mimic dementia, also manifesting additional clinical features, such as epileptic seizures and psychiatric symptoms.
