[Bilingualism as a factor in the protection of Alzheimer's disease: a systematic review].

CONCLUSIONS: The aforementioned studies have found a delay at the time of diagnosis or at the onset of clinically significant symptoms, between 4.5 years and 7 years; thus, bilingualism could be considered a contributing factor of the cognitive reserve and as a consequence a probable protection factor to prevent or slow the onset of AD and its subsequent progression.
