Estudo liga memória excepcional de superidosos a maior número de neurônios novos

(Folha de S.Paulo - Em cima da hora - Principal / 2026-03-11 10:00)

Resumo objetivo:
Um estudo publicado na Nature revela que os "superidosos" (pessoas com 80+ anos e memória equivalente à de indivíduos 30 anos mais jovens) possuem aproximadamente o dobro de neurônios novos no hipocampo em comparação com idosos de memória normal. A pesquisa associa essa neurogênese preservada a características genéticas e epigenéticas únicas, que podem conferir resiliência ao envelhecimento cerebral. Além disso, o trabalho reforça a plasticidade cerebral mesmo em idades avançadas e oferece evidências biológicas sobre a capacidade de geração de neurônios na vida adulta.

Principais tópicos abordados:
1. A relação entre neurogênese no hipocampo e a preservação excepcional da memória em "superidosos".
2. O debate sobre a plasticidade cerebral e a capacidade de gerar novos neurônios na idade adulta.
3. As diferenças quantitativas e qualitativas (genéticas/epigenéticas) nas células neuronais entre grupos de idosos com cognição normal, comprometida, Alzheimer e superidosos.
