It has now been more than a month since former President Donald Trump was nearly killed by a would-be assassin's bullet that barely missed his head and miraculously only grazed his right ear as he spoke on stage at an outdoor campaign rally in Pennsylvania.

Yet, while the relatively minor and superficial injury to his ear may be almost fully healed by now, it is suspected by some that Trump has not yet fully recovered psychologically from the near-fatal incident and may be suffering from post-traumatic stress disorder, or PTSD, according to the Daily Mail.

That suspicion reportedly stems from concerns of some allies that Trump has been acting strange in a "self-destructive spiral" since the shooting -- including allegedly repeatedly watching the video clip of himself narrowly dodging an almost certain death on July 13.

Trump may be suffering psychological trauma from shooting

Vanity Fair's Gabriel Sherman -- a known fabulist to be taken with a grain of salt, to be sure -- reported this week that he is hearing concerns from some of former President Trump's allies and campaign staffers that he is "sabotaging" his own campaign and "choosing to lose" by way of his own actions.

One possible reason for Trump's supposed errant behavior is that he continues to deal with the psychological trauma of the assassination attempt that occurred in Butler, Pennsylvania last month.

"He’s been watching that seven-second clip of how close he was to getting shot right in the head -- over and over and over again," an unnamed elected Republican described as close to the campaign allegedly told VF. "He may actually legit have PTSD."

That theory was perhaps bolstered by the claimed comments of an unnamed campaign official, who allegedly told the outlet that Trump's "been through a lot" and continues to dwell on the shooting incident that nearly ended his life.

Of course, while Vanity Fair's devoutly anti-Trump Sherman is well-known for making up negative things about the former president, he may actually be correct here, as PTSD is a very real thing.

PTSD is a legitimate cause for worry

According to the National Institute of Mental Health, post-traumatic stress disorder is a psychological condition that may develop for some people following a particularly "shocking, scary, or dangerous event," including things like experiencing or witnessing "a physical or sexual assault, abuse, an accident, a disaster, or other serious events."

It has likely been too soon since the attempted assassination for Trump to be formally diagnosed with PTSD, but some of the symptoms that might result in such a diagnosis include repeatedly re-experiencing the incident -- such as constantly rewatching the video clip -- avoidance of certain things that may remind a victim of the trauma, and notable negative changes to one's behavior, cognition, and mood.

There are a range of therapeutic and medical treatments for PTSD, and it seems safe to presume that Trump's closest allies and family are keeping a close eye on him for signs that such treatments may prove necessary if, in fact, he is suffering psychologically from his brush with death.

Possibility of psychological injuries remains a concern

This isn't the first time that the topic of PTSD in connection to the attempted assassination of former President Trump has been raised, as CNN's chief medical correspondent, Dr. Sanjay Gupta, made note of that possibility in an article he wrote less than a week after the shooting incident.

While the physician acknowledged that Trump appeared to be fine physically, by all accounts, it was the unknown and unseen potential psychological injuries that he was still somewhat concerned about, especially given that those mental injuries sometimes take a while to fully develop and be displayed.

"In the chaos that immediately follows being shot, these psychological impacts don’t always manifest," Dr. Kenji Inaba, a trauma surgeon at the University of Southern California, told CNN. "It can come up later on, and it’s something that we always need to be acutely aware of."
