Top aide Huma Abedin warned the Clinton campaign team in a 2015 e-mail that Hillary was “still not perfect in her head” and would have to “stick to notes” during an event.

The e-mail is among thousands hacked from Clinton campaign chairman John Podesta’s account that have been released by WikiLeaks.

The exchange came at the end of a discussion among staffers about how Clinton would address then-GOP candidate Jeb Bush’s use of Super PAC money to fund his campaign.

“Yes. If she feels need to address Jeb directly — would suggest the pivot,” Clinton’s director of communications, Jennifer Palmieri, wrote, referring to the remarks the team was preparing.

Abedin responded, “She’s going to stick to notes a little closer this am, still not perfect in her head”

It was unclear whether Abedin was referring to a serious ailment.

Clinton’s opponents have speculated that she still may be feeling the effects of a concussion suffered in December 2012, after which she was hospitalized with a blood clot near her brain.
