00:00Scientists in the Netherlands may have found a clue about why some brains resist Alzheimer's.
00:05The research comes from the Netherlands Institute for Neuroscience and was published in CellStemCell.
00:11Senior author Evgenia Salta says around 30% of older adults who develop Alzheimer's disease never experience its symptoms.
00:19The team studied brain tissue from the Netherlands Brain Bank.
00:22They compared people with no detectable brain pathology, patients with Alzheimer's dementia, and resilient people.
00:29Resilient people had Alzheimer's changes but stayed mentally sharp.
00:33Immature neurons were found in all groups, in donors with an average age over 80.
00:38In resilient people, those cells showed signs of survival and damage protection with lower inflammation signals.
00:45The researchers caution that this is based on tissue data patterns.
00:48The study does not show these cells prevent dementia, and practical treatments remain a distant possibility.
