Anticuerpos Anti-Titina en Encefalitis Autoinmune: ¿Casualidad o Causalidad? A propósito de un caso

Autoimmune Encephalitis, are an emerging condition, characterized by the sudden onset of psychotic or depressive symptoms “de novo”, refractory seizures or epilepsy, or rapidly progressive dementias. The autoimmune encephalitis are associated to various triggered phenomena as a previous viral infections among others; it’s related to the presence of antineuronal and/or onconeuronal antibodies, and there must be studied when autoimmune encephalitis is suspected. It is very important to develop a presumptive and early diagnosis, since steroid therapy –on opportunity time– can change its evolution towards clinical improvement. We present a patient with autoimmune encephalitis, and positive anti-Titin antibodies (usually presents in thymoma and myasthenia gravis) not associated with known neoplasia, and with a good response to steroids.
