Prior to George Floyd’s death, Officer Thomas Lane reportedly said, “I am worried about excited delirium or whatever” to his colleague, Officer Derek Chauvin.1 For those of us who frequently work with law enforcement and in correctional facilities, “excited delirium” is a common refrain. It would be too facile to dismiss the concept as an attempt by police officers to inappropriately use medically sounding jargon to justify violence. “Excited delirium” is a reminder of the complex situations faced by police officers and the need for better medical training, as well as the attention of research on this commonly used label.
Many law enforcement facilities, in particular jails that receive inmates directly from the community, will have large posters educating staff on the “signs of excited delirium.” The concept is not covered in residency training programs, or many of the leading textbooks of psychiatry. Yet, it has become common parlance in law enforcement. Officers in training receive education programs on excited delirium, although those are rarely conducted by clinicians.
In our practice and experience, “excited delirium” has been used by law enforcement officers to describe mood lability from the stress of arrest, acute agitation from stimulant or phencyclidine intoxication, actual delirium from a medical comorbidity, sociopathic aggression for the purpose of violence, and incoherence from psychosis, along with simply describing a person not following direction from a police officer.
Our differential diagnosis when informed that someone was described by a nonclinician as having so-called excited delirium is wider than the Diagnostic and Statistical Manual (DSM). In addition, the term comes at a cost. Its use has been implicated in police-related deaths and brutality.2 There is also concern of its disproportionate application to Black people.3,4
Nonetheless, the term “excited delirium” can sometimes accurately describe critical medical situations. We particularly remember a case of altered mental status from serotonin syndrome, a case of delirium tremens from alcohol withdrawal, and a case of life-threatening dehydration in the context of stimulant intoxication. Each of those cases was appropriately recognized as problematic by perceptive and caring police officers. It is important for police officers to recognize these life-threatening conditions, and they need the language to do so. Having a common label that can be used across professional fields and law enforcement departments to express medical concern in the context of aggressive behavior has value. The question is: can psychiatry help law enforcement describe situations more accurately?
As physicians, it would be overly simple to point out the limited understanding of medical information by police and correctional officers. Naming many behaviors poses significant challenges for psychiatrists and nonclinicians. Examples include the use of the word “agitation” to describe mild restlessness, “delusional” for uncooperative, and “irritable” for opinionated. We must also be cognizant of the infinite demands placed on police officers and that labels must be available to them to express complex situations without being forced to use medical diagnosis and terminology for which they do not have the license or expertise. It is possible that “excited delirium” serves an important role; the problem may not be as much “excited delirium,” the term itself, as the diversion of its use to justify poor policing.
It must be acknowledged that debates, concerns, poor nomenclature, confusing labels, and different interpretations of diagnoses and symptoms are not unusual things in psychiatry, even among professionals. In the 1970s, the famous American and British study of diagnostic criteria,showed that psychiatrists used the diagnosis of schizophrenia to describe vastly different patients.5 The findings of the study were a significant cause of the paradigm shift of the DSM in its 3rd edition. More recently, the DSM-5 field trials suggested that the field of psychiatry continues to struggle with this problem.6 Nonetheless, each edition of the DSM presents a new opportunity to discuss, refine, and improve our ability to communicate while emphasizing the importance of improving our common language.
Emergency physicians face delirious patients brought to them from the community on a regular basis. As such, it makes sense that they have been at the forefront of this issue and the American College of Emergency Physicians has recognized excited delirium as a condition since 2009.7 The emergency physician literature points out that death from excited delirium also happens in hospitals and is not a unique consequence of law enforcement. There is no accepted definition. Reported symptoms include agitation, bizarre behavior, tirelessness, unusual strength, pain tolerance, noncompliance, attraction to reflective surfaces, stupor, fear, panic, hyperthermia, inappropriate clothing, tachycardia, tachypnea, diaphoresis, seizure, and mydriasis. Etiology is suspected to be from catecholaminergic endogenous stress-related catecholamines and exogenous catecholaminergic drugs. In particular is the importance of dopamine through the use of stimulants, specifically cocaine. The literature makes some reference to management, including recommendations aimed at keeping patients on one of their sides, using de-escalation techniques, and performing evaluation in quiet rooms.
We certainly condone and commend efforts to understand and define this condition in the medical literature. The indiscriminate use of “excited delirium” to represent all sorts of behaviors by nonmedical personnel warrants intelligent, relevant, and researched commentary by physicians. There are several potentially appropriate ways forward. First, psychiatry may decide that excited delirium is not a useful diagnosis in the clinical setting and does not belong in the DSM. That distinction in itself would be potentially useful to law enforcement officers, who might welcome the opportunity to create their own nomenclature and classification. Second, psychiatry may decide that excited delirium is not a useful diagnosis in the clinical setting but warrants a definition nonetheless, akin to the ways homelessness and extreme poverty are defined in the DSM; this definition could take into account the wide use of the term by nonclinicians. Third, psychiatry may decide that excited delirium warrants a clinical diagnosis that warrants a distinction and clarification from the current delirium diagnosis with the hyperactive specifier.
At this time, the status quo doesn’t protect or help clinicians in their respective fields of work. “Excited delirium” is routinely used by law enforcement officers without clear meaning. Experts have difficulty pointing out the poor or ill-intended use of the term without a precise or accepted definition to rely on. Some of the proposed criteria, such as “unusual strength,” have unclear scientific legitimacy. Some, such as agitation or bizarre behavior, often have different meanings to nonphysicians. Some, such as poor clothing, may facilitate discrimination. The current state allows some professionals to hide their limited attempts at de-escalation by describing the person of interest as having excited delirium. On the other hand, the current state also prevents well-intended officers from using proper terminology that is understood by others as describing a concerning behavior reliably.
We wonder whether excited delirium is an important facet of the current dilemma of reconsidering the role of law enforcement in society. Frequent use of “excited delirium” by police officers is itself a testament to their desire to have assistance or delegation of certain duties to other social services, such as health care. In some ways, police officers face a difficult position: Admission that a behavior may be attributable to excited delirium should warrant a medical evaluation and, thus, render the person of interest a patient rather than a suspect. As such, this person interacting with police officers should be treated as someone in need of medical care, which makes many interventions – including neck compression – seemingly inappropriate. The frequent use of “excited delirium” suggests that law enforcement is ill-equipped in handling many situations and that an attempt to diversify the composition and funding of emergency response might be warranted. Psychiatry should be at the forefront of this research and effort.
