Scientists discover why some brains resist Alzheimer's
Researchers are investigating why some individuals with Alzheimer's pathology do not exhibit cognitive decline, focusing on the role of immature neurons in the brain. This study explores the potential for adult neurogenesis to provide cognitive resilience against neurodegenerative disease.
Why it matters
Understanding the mechanisms of cognitive resilience could lead to breakthrough therapeutic strategies for treating or preventing dementia.
Some people remain mentally sharp even though their brains contain the biological changes associated with Alzheimer's disease. A new study from the Netherlands Institute for Neuroscience suggests that the answer may lie in how a rare group of brain cells, called immature neurons, responds to damage. The findings offer new insight into cognitive resilience, the brain's ability to continue functioning despite disease.
