Are Smart People Grumpier' 10, 2006 -- Grumpy and brainy may go together in older folks; but young people tend to be more open and friendly if they're bright, researchers report Neuroticism didn't appear linked to intelligence test scores at any age This was not so for the older group (61-89).

So this study doesn't represent a cross section of older adults Speaking of memory, the researchers also noticed that short-term memory test scores were better for the over-60s who scored high on conscientiousness and openness.
