Minor cognitive decline

1. Verbal fluency predicts minor cognitive decline in humans (79.5% accuracy, 95% CI [73.2%, 84.9%]).

   “this pattern of relative performance could be used to identify recent decline with 79.5% accuracy, 95% CI [73.2%, 84.9%], even without knowledge of overall performance.”

2. Minor cognitive decline is associated with verbal fluency in humans.

   “having experienced minor cognitive decline in the preceding 12 to 18 months was associated with a pattern of higher performance in fluency relative to performance in six other cognitive domains.”
