PHOENIX -- Jodi Arias' psychologist diagnosed her with a form of Post Traumatic Stress Disorder (PTSD), to explain her memory problems.
Arias claims she shot her ex-lover, Travis Alexander, in self defense in 2008, but cannot remember stabbing him 27 times, slitting his throat, or dragging him into the shower.
Arias' defense team says her 'fog,' as she calls it, is the result of PTSD.
Cesar Gamez, who runs North Phoenix Counseling, says PTSD can come and go with patients.
"It's not an excuse, but can be used as an explanation," Gamez told 3TV.
"You can certainly be exposed to PTSD by being exposed to trauma, whether you're the victim, aggressor, or innocent bystander," Gamez said.
Still, Arias' diagnosis is causing a stir among veterans.
Twitter and blogs are full of veterans who are suffering from PTSD, claiming Arias diagnosis is "nauseating" and "offensive."
"It's insulting if someone's using it as an excuse," Iraq War Veteran Steve Crowley told 3TV.
Crowley created www.heroranch.com and posts podcasts about various veteran topics.
"I can understand why a lot of veterans could be really angry. They throw the PTSD card out for something like [the Arias case], and it lessens it for us," Crowley said.
Arias' trial resumes Monday.
