For every half an egg on average that someone consumed per day over those 22 years, there was a 10% lower risk of Alzheimer's.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

There was a clear and consistent association with more egg consumption and lower rates of Alzheimer's dementia.
Eggs get vilified every day because of their cholesterol content. What we know is that that cholesterol is good for your brain and the choline in the eggs is clearly and consistently associated across studies with lower rates of dementia like Alzheimer's.
At the end of the study, the men who had eaten three or more eggs per day clearly had a much lower risk of Alzheimer dementia.
In the other study, eating 2 or more eggs per week was associated with a 47% reduction in Alzheimer's disease risk over a nearly 7-year follow-up period.
In one study, a higher egg intake was associated with less of a decline in verbal fluency among women during a 4-year period, with those consuming 5 or more eggs per week experiencing the greatest benefit.
an analysis of brain samples from participants who died during the study revealed that consuming 1 or more eggs per week reduced the odds of having a pathological diagnosis of Alzheimer’s disease by up to 49%—indicated by the presence of fewer plaques and neurofibrillary tangles.
