How do individuals with altered mental status present?
· Altered mental status (AMS) is a very common emergency case, but the exact etiology of many AMS patients is unknown. Patients often manifest vague symptoms, thus, AMS diagnosis and treatment are highly challenging for emergency physicians. The aim of this study is to provide a framework for the assessment of AMS patients.

What is altered mental status?
• Altered mental status is a common presentation in the emergency department (ED). There are many causes of altered mental status, and often the exact cause is not apparent in the ED. The role of the ED provider is to stabilize the patient, treat causes that are rapidly reversible (hypoglycemia, hyperthermia/hypothermia) and initiate diagnostic testing and treatment for life-threatening causes (trauma, intracranial lesions, sepsis).
When obtaining a history from an altered patient, the initial goal should be to determine why the patient was brought to
When obtaining a history from an altered patient, the initial goal should be to determine why the patient was brought to the ED. EMS can provide clues to the etiology. The more history EMS can provide, the better. Family members or caretakers can provide a timeline of when the patient was “normal” and the transition to the present altered state, in addition to any pertinent prior history.
What is delirium in mental health?
Delirium, also known as an acute confusional state, is a transient disorder characterized by impaired attention, perception, thinking, memory, and cognition. Delirium can be thought of as acute brain failure and is the final common pathway of multiple mechanisms. 3 According to the official definition in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), delirium involves a disturbance in attention and awareness that is acute and tends to fluctuate. 4 This can include a disturbance in attention or a change in an additional cognitive domain. Delirium can be caused by either somatic or medication factors, and it usually develops over the course of a few days. Sleep-wake cycles may be disrupted, and symptoms tend to be worse at night. Levels of alertness may be reduced, and activity levels may fluctuate rapidly. 1
What is the best treatment for delirium in older patients?
Patients can pose a risk to themselves since they often are a fall risk and pick at tubes and lines because they are confused and agitated. For many years, delirium in the inpatient and emergency setting has been treated with antipsychotic medications, such as haloperidol, quetiapine, ziprasidone, and other first- and second-generation antipsychotics. Pharmacological management is especially common at night and in the ED when there is not enough medical staff to watch patients and, therefore, medication is deemed necessary.
How to diagnose elevated ICP?
One new technology that can be considered for use in an altered mental status patient is point-of-care ultrasound to diagnose increased ICP. Ultrasound is an easy and rapid way to diagnose increased ICP when more advanced tests are not available. Various causes of increased ICP, including head injury, spontaneous intracranial bleeds, metastatic tumors, and more, can contribute to altered mental status. Unfortunately, papilledema on physical exam is difficult to diagnose. Many emergency medicine physicians do not believe in their ability to perform this exam well, and it is even more difficult to perform on an unconscious, intubated, or paralyzed patient. Further, papilledema seen on funduscopic exam is a delayed PE manifestation of elevated ICP. A high-frequency, linear ultrasound probe can be used to measure a normal optic nerve sheath diameter (ONSD), which should be less than 5.0 mm, typically measured 3 mm posterior to the globe bilaterally. The average of two measurements should be used to correlate with ICP. When the ONSD average is greater than 5 mm, suspect elevated ICP. 37 While the bedside exam is very specific, it is not sufficiently sensitive to rule it out. Therefore, when positive, the diagnosis is made. When negative, further testing still is warranted.
Why is neurologic exam important?
A thorough neurologic exam is paramount when examining any altered patient because focal findings suggest structural abnormalities. Pupils and extraocular movements also are important when assessing for various toxidromes. Asking the patient to walk when feasible is a valuable aspect to the physical exam, since different types of ataxia may suggest various differential diagnoses from stroke to toxicological causes, ingestions, and even toxic levels of therapeutic medications.
What is the importance of documentation in an emergency medical case?
When an emergency physician cares for a patient who is acutely confused, altered, violent, or presents a danger to himself/herself, family, or healthcare workers, the physician will need to treat without informed consent. This can present a potential legal issue if appropriate precautions are not taken. Proper documentation during these cases is essential. There have been numerous cases for which physicians were acting in the best interest of a patient, but because of failed documentation, the physician and hospital were sued. Having another physician present during these decisions and, further, having that physician document in the chart “I agree” with the necessary precautions taken, can be extremely supportive if legal action is taken at a later date. 38 When the patient’s family members are present, explaining to them the pros and cons, and need for intervention, and further documenting this discussion and their support are essential. 38 If the physician is unable to obtain consent for treatment for whatever reason, it is crucial to document three factors: the intervention is emergent; consent could not be obtained; and the intended treatment was specifically for the benefit of the patient. 39 A classic case in which the physician was protected by appropriate documentation is Craig L. Miller v. Rhode Island Hospital et al. 40 In this case, the patient was intoxicated, violent, and deemed to not have capacity to perform informed consent. He had an invasive diagnostic procedure performed, and then sued the hospital for acting against his wishes. The hospital was not held responsible.
What is altered mental status?
Altered mental status (AMS) represents a broad spectrum of disease processes, making treatment modalities equally broad and varied. If the cause for AMS is found, the prehospital care providers will then transition to that more-specific protocol. However, emergency medical service (EMS) providers have limited time to evaluate these undifferentiated patients. Therefore, guidelines for assessment and initial treatment prior to arriving at an emergency department (ED) are essential. The prevalence of AMS in the prehospital care setting is not well known given the limited research in this area. One California county found 27% of all EMS patients had an abnormal Glasgow Coma Scale (GCS).1ED data report AMS at a prevalence between 1–10% of visits.2–4Prehospital protocols and treatment recommendations for AMS vary widely across the U.S.5We provide a summary of available evidence for prehospital assessment and treatment of patients with undifferentiated AMS and additionally evaluate consistency across California protocols.
What causes AMS in elderly?
Another cause of AMS is hypoxia , especially in the elderly population, which can be evaluated with pulse oximetry and may be considered the fifth vital sign.16,17A similar point-of-care test is the pulse CO-oximeter. When looking at studies that compared Rad 57 (a type of pulse CO-oximeter) to the gold standard blood test, the evidence was conflicting, with wide ranges of precision and accuracy found.18–20Since CO poisoning is not a common cause of AMS and since pulse CO-oximeter’s clinical accuracy remains unclear, we do not currently recommend evaluating for CO poisoning in the undifferentiated AMS patient.
When was the AMS protocol reviewed?
The clinical protocols were reviewed during the months of November 2016 and July 2017.

Older adults may have AMS after changes in their medicines, heart attacks, or hip fractures. Infections, such as urinary tract infections or pneumonia, can also increase the risk for AMS. A medical history of high blood pressure, heart problems, diabetes, or psychiatric illness increases the risk for AMS.
What is the challenge of diagnosing a patient with a change in mental status?
Diagnosing a patient with a change in mental status can be a daunting challenge in the Emergency Department (ED). Some presentations are clear; a patient who is postictal after a seizure or a diabetic patient who is hypoglycemic. At times the clinical picture is more subtle and not easily identified. Enlisting historical data from multiple sources and maintaining a high index of suspicion is necessary to detect the behavioral marker of potentially catastrophic pathology.
What is an AMS patient?
The “AMS” label may be applied to a patient who is postictal or perhaps a patient who has dementia. Because the varied presentations that can range from global CNS depression to confusion to the other extreme, agitation, it is important to be clear with terminology on how we describe a patient’s mental status.
What does AMS mean in medical terms?
Unfortunately, there is no classic presentation for a patient with AMS. The terms, “Altered mental status” and “altered level of consciousness” (ALOC) are common acronyms, but are vague nondescript terms. The same can be said about terms such as lethargy or obtundation. Both represent some level of decreased consciousness but are more subjective descriptors than true objective findings. The “AMS” label may be applied to a patient who is postictal or perhaps a patient who has dementia. Because the varied presentations that can range from global CNS depression to confusion to the other extreme, agitation, it is important to be clear with terminology on how we describe a patient’s mental status.
Why do we use diagnostic tests?
Generally, diagnostic testing is used to rule in or rule out items on your differential diagnosis and should not be ordered in a “shot-gun” fashion . In the case of a patient with an undifferentiated AMS presentation, however, liberal use of diagnostic studies is frequently necessary because of the breadth of the differential diagnosis and the high stakes involved in delaying appropriate treatment.
What is the abcdef approach?
The “ABCDEF approach” provides a good opportunity to check for quickly reversible causes of AMS. Ideally this should happen as the patient is being placed on a monitor and IV access is being established.
What does lack of movement on one side of the body night mean?
Pay attention to spontaneous movements. Lack of movement on one side of the body night indicate stroke while lack of movement below a certain level of the body could indicate an acute spinal cord syndrome. If there is any suspicion of trauma the cervical spine should be stabilized.
How is differential diagnosis determined?
Initial diagnostic maneuvers are primarily determined by the history and physical exam findings. These clues will allow you to build a working differential diagnosis based on the major categories that cause. Often presumptive treatment is begun at this point (see below). Diagnostic imaging and laboratory tests are ordered to narrow down or confirm the differential diagnosis. Remember, in Emergency Medicine, diagnosis and treatment is a dynamic process. As treatment is initiated, it is important to frequently reassess the patient. How are they responding to the interventions? Their response is often what cinches the diagnosis or reminds us to look in a different direction.
