Bilingualism has been shown to contribute to increased resilience against cognitive aging. One of
the key brain structures linked to memory and dementia symptom onset, the hippocampus, has
been observed to adapt in response to bilingual experience – at least in healthy individuals.
However, in the context of neurodegenerative pathology, it is yet unclear what role previous bilingual experience might have in terms of sustaining integrity of this structure or related behavioral
correlates. The present study adds to the limited cohort of research on the effects of bilingualism
on neurocognitive outcomes in Mild Cognitive Impairment (MCI) using structural brain data.
We investigatewhether bilingual language experience (operationalized as language entropy) results
in graded neurocognitive adaptations within a cohort of bilinguals diagnosed with MCI. Results
reveal a non-linear effect of bilingual language entropy on hippocampal volume, although they
do not predict episodic memory performance, nor age of MCI diagnosis.
