A Northwestern University study identified 'superagers', older adults (80+) who exhibit markedly better cognitive function compared to their peers. To qualify, participants had to recall at least 9 out of 15 words on a verbal learning test, with only about 10% of cognitive normal seniors meeting this criterion. Out of 290 participants, 101 were classified as superagers, averaging 90 years old, and despite varied health conditions, they reported stronger social connections. Neuroimaging revealed unique brain characteristics, including a thicker anterior cingulate cortex and fewer tau tangles, indicating potential insights into neurodegeneration and memory preservation.
