The effects of lifelong bilingualism on white matter integrity in dementia


  • Bilingual individuals demonstrate less white matter disintegration and later dementia onset.

Why this matters

  • Dementia is a neurodegenerative disorder that results in cognitive decline and memory deterioration in affected individuals. It has been suggested that bilingualism may enhance cognitive functioning and delay the onset of dementia.

  • Understanding the effect of bilingualism on key regions of the brain linked to the brain’s memory circuity may inform new methods to prevent or delay the development of dementia.
