Agnus isn't a Star Fleet Officer.I guess they don't do psych evaluations in this future since her undiagnosed issues has put the entire mission at risk.
She's a Scientific Consultant whose work FOR Star Fleet was shut down right at the height of her accomplishments with Brophy.
(it's surprising how much can be ignored when results are the only goal)
She was essentially twiddling her thumbs when Picard approached her.
Also, Picard was not working for Star Fleet when he did approach her, so he didn't have the usual over abundance of info to work with.
