Hi all, I want to share my concerns, hope you can tell me if this is possibly some form of paraphasia or aphasia.

He can speak and write normally most of the time. Sometimes with more difficulty, but don’t we all. He is above average intelligent, though he has noticed some cognitive issues, but all very minor.

However, he has periods when, especially when tired, he uses wrong words.

It is often a noun, and most of the time it is a noun that sounds a bit similar.
Like saying “Can you get me the candle, candle....cradle....c....c..... card”

He squints, closes his eyes a bit, and physically pushes the word out, kind of like a stutter. He knows the word isn’t right, he know’s candle or cradle isn’t want he wants to say and he gets frustrated. After a few misses and some focusing he does find the right word.

“Will you please look at the water, w-w, wa...winter.”
He pointed at the window and get’s a bit frustrated.
“W...window!” And sighs and laughs.

Sometimes it’s a verb, that too similar sounding, mostly starting with the same letter(s).

Mind, it doesn’t happen daily, so it’s a bit hard to tell docs about. However, we as his family, do know it isn’t normal or just “tired”.
Is this a form of (par) aphasia and if so, which one?

I’ve read about paraphasia but that seems more like it’s saying “apple” or “fruit” when wanting to say “pear”.
