ST. PAUL, Minn. — Minnesota could become the next state to ban police officer training on “excited delirium,” a term that has been rejected by major medical associations in recent years as pseudoscience used to justify deaths in law enforcement custody.
Police officers invoking excited delirium during fatal interactions, such as in the murder of George Floyd, have generated a wave of criticism over the term’s legitimacy in the United States. Colorado and California both passed laws prohibiting its use among emergency responders since October, with more state legislatures poised to follow suit.
Minnesota’s DFL-led House of Representatives passed a broad public safety bill last month with a provision to legally ban the state’s police licensing board from providing, certifying or reimbursing training on excited delirium. There is currently no companion bill in the Senate, so it remains to be seen whether the ban will be codified into law as both chambers negotiate final language in the last weeks of the session, ending May 20.
Excited delirium usually refers to a person possessed by a potentially deadly form of agitation, sometimes abetted by drug abuse, with symptoms of aggressive behavior, profuse sweating, public nudity, mouth foaming and superhuman strength. In 2021, the American Medical Association released a public statement opposing the diagnosis as “a manifestation of systemic racism.” The American Psychiatric Association followed with a similar rejection, and the National Association of Medical Examiners now says it should never be cited as a cause of death.
“Right now there’s not a single medical association that upholds excited delirium as legitimate,” said Dr. Altaf Saadi, a neurologist at Massachusetts General Hospital who has called for the end of the term’s use in the United States.
Bill author Rep. Jessica Hanson, DFL- Burnsville, declined an interview request for this story. In a committee hearing last month, Hanson described excited delirium as a diagnosis “rooted in anti-Black racism.”
“The term excited delirium appeared out of thin air in Florida in the 1980s,” Hanson said. “It has no basis in science, no functional meaning in medicine and no clear diagnostic criteria nor symptomatology.”
Minnesota’s statewide police union has taken a neutral position on the bill, said Leslie Rosedahl, spokeswoman for the Minnesota Police and Peace Officers Association. Excited delirium has previously been banned in training for Minneapolis police by order of Mayor Jacob Frey.
A doctor in Miami first used the term in 1981 to describe a drug smuggler who died after a bag of cocaine ruptured in his digestive tract. The tear sent a “flood of cocaine” into the man’s body, and in the hours before he died, “his behavior became so dangerous that he had to be restrained by six hospital attendants,” according to an article in medical journal Psychology Medicine.
In the 1990s and 2000s, doctors and medical examiners began to use the term more broadly, often to describe people who died in custody of police or in jails, including after the use of a stun gun.
In the medical community, paramedics and police often encounter agitated, erratic people who are difficult to calm and may pose a danger to themselves or others. Critics say excited delirium has become a vague umbrella term to describe a wide array of unrelated causes, used to justify use of force and sometimes delaying appropriate medical recourse for a person in duress.
“The medical support for this diagnosis crumbled,” said Dr. Jennifer Brody, an internal medicine and addiction specialist who teaches at Harvard Medical School. “There’s just no medical grounds to stand on.”
In the past five years, two high-profile cases of people dying in police custody brought new attention from the mainstream medical community to excited delirium.
In 2019, Elijah McClain died after police in Aurora, Colo. restrained him in a chokehold and paramedics injected him with an overdose of the sedative ketamine. The 23-year-old Black man had been walking home from buying iced tea, apparently dancing to music on his headphones, when a neighbor called 911 to report he was acting “sketchy.” Afterward, the paramedics, who have since been convicted of criminal negligence, said they believed McClain was suffering from excited delirium.
The next year, Minneapolis police officer Derek Chauvin killed Floyd by kneeling on his neck. In a federal civil rights trial, three officers convicted in Floyd’s death testified extensively that they believed Floyd may have been suffering from excited delirium. Officer Alex Kueng said he believed the condition could cause Floyd to “spring back to life” and become a threat once again, even after he was unresponsive. In a separate trial, Chauvin’s attorney argued his client was acting as a “reasonable police officer” watching for signs of excited delirium.
The Minneapolis police department’s previous training told officers that excited delirium was an extreme form of agitation that manifests as superhuman strength, bizarre speech and aggressive conduct. A training slideshow, shown to the jury, featured an image of officers pinning a man with their knees to subdue him, similar to how Chauvin pinned Floyd. Lane, who mentioned excited delirium on the scene, said he was taught to restrain people in such condition in order to “keep a person from thrashing, hold them in place.”
Saadi said she hadn’t heard of excited delirium before these cases, which prompted her to review the science behind it.
“It’s a convenient diagnosis, because on one hand it can be used to justify police brutality, and on the other hand it can also be used to explain sudden death in police custody,” she said. “That’s how we saw it was being used —in both ways.”
