All too common. Despite our best efforts, even the most detailed neuropsychological battery does a very poor job at detecting certain categories of cognitive changes -- especially in patients who were above average at baseline.

I'm a neurosurgeon and we commonly advise our patients: Even after a "perfect" or minimal surgery without any evidence of periprocedural stroke or complication, you may not ever be the same again. Sometimes it takes months for these changes to be noted, sometimes it's only even noticed by family members. Odd word finding difficulties, perception changes, memory/concentration issues; the gamut is endless. As we say, no one's the same when the air hits your brain.
