To the Editor:
The article by Sánchez Espinoza et al., published in the Revista Ecuatoriana de Neurología, makes a valuable contribution by addressing the Heidenhain variant of Creutzfeldt-Jakob disease (CJD), highlighting its clinical evolution and the relevance of differential diagnosis regarding other rapidly progressive dementias. This Letter to the Editor complements that discussion by emphasizing the persistent, transmissible, and potentially zoonotic nature of prion diseases in the Latin American context, in light of recent research.
