Did any popes exhibit symptoms of mental illness (dementia, Alzheimer, etc.)while ruling into their old age?

If so, was it ever acknowledged and was anything done to mitigate potential damages to the church?

The one documented incident of this that I know of falls within the 20 year rule of this sub.

was anything done to mitigate potential damages to the church?

This could be asked as a theological question, but that is also not appropriate for me to answer here.

Sorry I couldn't be more helpful.
