Examines a brain‑aging clock study linking lifelong language experience to graded differences in neural aging within a multilingual cohort.
Key Takeaways
- Brain‑aging clock was trained on 728 individuals' MEG connectivity profiles
- Two, three, and four languages corresponded to roughly 6, 7, and 13 years younger brains
- Higher language proficiency and earlier second‑language acquisition were linked to greater brain‑age delay
