Have you ever wondered why Paul says you are saved if ye keep in memory the Gospel? Does that mean forgetting it could cost you salvation?
But look at the problem Paul is actually correcting. In verse 12, some among the Corinthians were saying there was no resurrection of the dead. Paul is not talking about dementia, brain injury, or ordinary forgetfulness. He is calling believers back to the Gospel he preached, especially the resurrection.
And notice what he later says. In verses 14 and 17, if Christ were not risen, their faith would be vain. That explains the warning far better than saying a saved person must maintain perfect memory for life.
The context matters. Keep in memory is about holding to the Gospel Paul preached, not keeping your brain perfectly functional.
A believer can suffer memory loss without losing eternal life. Forgetting the Gospel does not make you unsaved, and it does not prove you were never saved.
