L'OMS affirme que jusqu'a 45% du risque de demence pourrait etre prevenu ou retarde

Resume large: L'OMS souligne des facteurs modifiables comme tabac, alcool, inactivite, isolement, pollution et maladies chroniques. Ce qui est confirme: The story is based on World Health Organization, with the source link and date preserved from the Spanish edition. Ce qui reste incertain: Follow-up depends on later source updates, technical papers, national implementation or mission milestones depending on the topic. Pourquoi cela compte: This localized edition keeps the editorial method visible: confirmed facts, context, uncertainty and source traceability.
