The Diagnosis

A real diagnosis describes a person so that they can be helped. This one describes a person so that what was done to them need not be explained. “Excited delirium” appears in no edition of the DSM; the American Medical Association rejected it in 2021; Canada’s Braidwood Inquiry, after hearing the evidence, called it a blind alley. And still it is taught to paramedics, written into a provincial drug protocol, and spoken at the scene of deaths in police custody — almost always after the force, almost always over a Black or racialized man, almost always as the thing that makes the rest unremarkable. Watch what the word does, not what it claims to be. It does two things. It puts a needle in an arm, and it takes a death off the books.

§01 — The word with two jobs

Most of the laundering this series documents converts something raw into something filed: a police want into a judge’s signature, a continuing regime into administrative law. “Excited delirium” is the same move compressed into a single clinical-sounding phrase that does two jobs in one breath. Forward, it licenses an intervention: a person is declared to be in a deadly medical state, so they must be subdued and sedated — for their own good. Backward, it explains an outcome: if that person then dies, they died of the condition, not of the restraint, the prone hold, the blows, or the drug. The same two words that authorize the force also absorb its result.

• P1 Agitation can be a real medical emergency. A person in genuine delirium can be in danger, and rapid sedation can, in the right hands, save a life. The case concedes this in full (§05).
• P2 For a diagnosis to do medical work, it must be a defined, recognized condition, assessed clinically — not a label applied at a scene to behaviour the assessor finds alarming.
• P3 “Excited delirium” is not that. It is in no diagnostic manual; it was rejected by the Braidwood Inquiry, by the AMA, and by most Canadian coroners; it is applied at the scene, by police and paramedics, disproportionately to Black men in restraint — and it was coined, as §02 shows, to explain away homicides.
• P4 So the phrase is offered as a medical fact while doing non-medical work: it licenses the injection and launders the death. That some agitation is genuinely a medical emergency does not make “excited delirium” a diagnosis — and using the real phenomenon to license the manufactured category is the laundering.

Counter: a word that arrives after the force, and mostly in the autopsy and the defence, is not describing what happened. It is dressing it.

§02 — Born in a morgue

The honest place to begin is the category’s birth, because its first act was a laundering and its first assumption was a racial one. Beginning in 1981, in Miami, the bodies of more than a dozen Black women — many of them sex workers — were found dead, partly undressed, with small amounts of cocaine in their systems. The Miami-Dade deputy medical examiner, Dr. Charles Wetli, who had just coined the term, ruled that they had died of “excited delirium” from cocaine and sexual activity — in his own words, “the male of the species becomes psychotic and the female of the species dies in relation to sex.” The deaths were, in other words, filed as a syndrome of the women’s own bodies. They were not: they had been murdered, one after another, by a serial killer, and the category had simply absorbed them as a medical curiosity.primary

The theory was racial from the start. Wetli publicly maintained that something like “seventy percent of people dying of coke-induced delirium are black males, even though most users are white,” and speculated the cause “may be genetic.” That is not a clinical finding; it is a belief about which bodies are built to die. The phrase should have died with the Miami murders. Instead, carried by training material and expert testimony, it migrated from the autopsy table to the street — from explaining deaths after the fact to authorizing force before it.analysis

The diagnosis’s first patients were a serial killer’s victims. It was invented to keep a death from being read as a killing.

Counter: a category that begins by mistaking murder for medicine has shown you, at its origin, exactly what it is for.

§03 — The blind alley

Canada did not have to take anyone’s word about this. It held a public inquiry. After Robert Dziekanski died in 2007, having been stunned with a conducted-energy weapon by RCMP officers at Vancouver’s airport — and after the Mounties speculated he had died of “excited delirium” — the Braidwood Inquiry took evidence on the term itself. Commissioner Thomas Braidwood’s conclusion was unambiguous: excited delirium is not a recognized medical or psychiatric condition; it is, in the inquiry’s framing, a blind alley — “a convenient way to avoid tough scrutiny of police practices that may contribute to death.” The diagnosis, examined under oath, did not survive contact with the evidence.primary

Nor is that one judge’s view. “Excited delirium” appears in no edition of the Diagnostic and Statistical Manual; the American Medical Association formally rejected it as a diagnosis in 2021, and the emergency-physicians’ body that had once lent it cover withdrew that support. By 2023, of the Canadian provincial coroners’ and chief medical examiners’ offices that answered the question, only New Brunswick said the term could still be cited as a cause of death. A category that the relevant institutions — a Canadian inquiry, the doctors’ associations, almost every Canadian coroner — have ruled is not a thing is the category on which a needle and an acquittal still rest.primary

Counter: when the only people who still need the word are the ones whose conduct it excuses, the word is not a diagnosis. It is a defence.

§04 — The injection

The forward job is not hypothetical, and it is not only American. In Ontario, the Advanced Life Support Patient Care Standards have carried a ketamine directive — 5 mg per kilogram, intramuscular, introduced in 2018 — for severe agitation, the indication once labelled “excited delirium” and since renamed in the directive itself toward “hyperactive delirium.” Ketamine is a powerful dissociative anaesthetic with a known rate of stopping people’s breathing. The category, in other words, is wired directly to a syringe: declare the state, give the dose. And the declaration is made by the people holding the person down, often before any real assessment.primary

The clearest specimen is across the border but structurally identical: in Aurora, Colorado, in 2019, Elijah McClain — twenty-three, unarmed, walking home — was stopped by police, restrained, and, after paramedics declared “excited delirium” without taking his pulse or speaking to him, injected with 500 mg of ketamine, a dose far beyond his body weight. He suffered cardiac arrest and died. The point is the sequence: the diagnosis came from the people restraining him, the dose followed the diagnosis, and the death followed the dose — and then the same phrase stood ready to explain it. The injection and the exoneration are the same word, used twice.primary

Declare the state, give the dose. The hand that holds the person down writes the diagnosis that sedates them.

Counter: a medical emergency is something a clinician finds by examining a patient. A label applied by the people restraining someone, to justify restraining them, is the opposite of an examination.

§05 — The strongest case for the word

The case is only worth making against its best opponent, so here it is, fairly. Severe agitation is real and can be lethal: a person in a genuine hyperactive delirium — from stimulants, withdrawal, metabolic crisis, psychosis — can overheat, exhaust their heart, and die, and they can be a danger to themselves and others in the meantime. Paramedics and emergency staff face such patients, and rapid sedation, competently dosed and monitored, can be the intervention that keeps someone alive long enough to be treated. None of that is in dispute, and a case that pretended otherwise would be lying. There are clinicians who argue, in good faith, that abandoning the label throws out a real and dangerous syndrome with the discredited name.

But notice what the strongest defence actually licenses. It licenses treating a genuinely sick person — assessed, dosed for their weight, monitored, in a setting where the person’s safety is the goal. It does not license a phrase applied by police to a person they are restraining, before assessment, as the reason to inject them; it does not license a coroner using it to close a use-of-force death; and it certainly does not rehabilitate a term coined to misfile murders. The real phenomenon argues for careful medicine. “Excited delirium,” as deployed, is the use of that real phenomenon’s authority to license something else. The gap between the two is the laundering.

Counter: “sometimes agitation is a medical emergency” is true, and is not a defence of the word. It is the borrowed credibility the word is spending.

§06 — The exoneration

The backward job is the one that keeps the word alive, and it is the one to handle with the most care, because it touches verdicts. The pattern is consistent and it is on the record. After Robert Dziekanski’s death, “excited delirium” was the explanation reached for — until the inquiry set it aside. After Abdirahman Abdi, a 37-year-old Black man in mental-health crisis, died following a violent 2016 arrest in Ottawa, the term circulated in the account of his death; the officer charged in the case, Constable Daniel Montsion, was acquitted of all charges in 2020, and the Ottawa police later settled a civil suit with the Abdi family. And in the McClain case, the paramedics were convicted in 2023 — and then, in June 2026, an appeal court reversed the homicide convictions over a jury-instruction error and ordered new trials, while upholding one paramedic’s assault conviction; prosecutors said they would appeal. The point here is narrow and it is not a verdict on any of those proceedings: it is that the same category that licensed the force is the category that, again and again, is present when the force is found to require no answer.primary

This is the move the series named in Case 20 · The Echo — where the verification step becomes the laundering step — and in Case 34 · The Apology, where the accountability arrow gets turned around. A death produces a process; the process meets a word that has already converted the death into a medical event; and the process, finding a medical event, finds nothing to adjudicate. The category does not need to win every case. It only needs to be in the room, doing to the question of responsibility what it did to the body: dissolving it.

Counter: relitigate nothing, and the pattern still stands — a death, a word, and a process that keeps arriving at the same place the word pointed.

§07 — The diagnosis, named

Strip it to the structure. There is a phrase that is not a diagnosis — not in the manuals, not in the inquiry’s findings, not in the doctors’ associations, not in almost any Canadian coroner’s office. And yet the phrase is kept, because it is useful in exactly the way a diagnosis is not. It travels with the people who restrain and sedate, and it does their two hardest jobs for them: it makes the injection look like care, and it makes the death look like nature. It was born misfiling the murders of Black women as a syndrome of their own bodies, and it carries that original function still — to relocate the cause of a racialized death from what was done to a person into something wrong with them. That relocation is the laundering. The word is the wash.

It makes the injection look like care, and the death look like nature. The cause moves from what was done to a person into something wrong with them.

The case keeps its limits in plain sight. It does not say agitation is never a medical emergency; §05 grants that it is. It does not re-try Constable Montsion, who was acquitted, or pronounce on the McClain appeal, which is unresolved; it reports the record as the record stands. It does not claim a single coordinating hand; the power of the word is that it needs none — a coroner here, a protocol there, a defence lawyer somewhere else, each reaching independently for the same convenient phrase. What it does claim is what Canada’s own inquiry already found: that “excited delirium” is a blind alley, and that a society which lets a blind alley stand in for a cause of death has agreed not to look down the street the death actually came from. So when a person dies in restraint and a clinical-sounding phrase arrives to make it medical, ask the question the word exists to prevent: not what was wrong with them, but what was done to them, and who is the word protecting now.
