What is altered mental status?
The evaluation and management of altered mental status are broad and require careful history and physical examination to eliminate life-threatening situations. Changes in consciousness can be categorized into changes of arousal, the content of consciousness, or a combination of both. Arousal includes wakefulness and/or alertness and can be described as hypoactivity or hyperactivity, while changes in the content of consciousness can lead to changes in self-awareness, expression, language, and emotions [1] [2].
Why is altered mental status important?
Altered mental status is a common presentation. It is important to recognize the early signs of altered mental status, identify the underlying cause, and to provide the appropriate care to reduce patient morbidity and mortality. The differential diagnosis is broad, and health care providers should be aware of this breadth. Underlying etiology can be as subtle as a urinary tract infection and as life-threatening as an embolic or hemorrhagic stroke. This activity outlines the approach toward differential diagnosis, evaluation, and treatment plans for patients presenting with altered mental status.
What is the term for a change in mental status?
Changes in mental status can be described as delirium (acute change in arousal and content), depression (chronic change in arousal), dementia (chronic change in arousal and content), and coma (dysfunction of arousal and content) [2].
What is delirium in psychology?
Delirium is typically an acute confusional state, defined by impairment of attention or cognition that usually develops over hours to days. Some patients may experience rapid fluctuations between hypoactive and hyperactive states, that may be interjected with periods of intermittent lucidity. A nearly pathognomonic characteristic of delirium is sleep-wake cycle disruption, which leads to “sundowning,” a phenomenon in which delirium becomes worse or more persistent at night [3][4].
What is the slow loss of memory and speech?
There are multiple types of dementia, but the most common are idiopathic (also referred to as Alzheimer disease) and vascular dementia. Idiopathic dementia is defined by the slow impairment of recent memory and orientation with remote memories and motor and speech abilities preserved. As the disease progresses, patients exhibit decreased performance in social situations, the inability to self-care, and changes in personality. Vascular dementia is similar to Alzheimer disease, although patients may have signs of motor abnormalities in addition to cognitive changes, and may exhibit a fluctuating step-wise decline, as multiple vascular events have an additive effect on the patient’s function [1][4][3].
What is depression characterized by?
Depression is characterized by personal withdrawal, slowed speech, or poor results of a cognitive test. Patients rarely have a rapid fluctuation of symptoms and are usually oriented and able to follow commands [1][4][3].
Which structure mediates arousal?
The ascending reticular activating system is the anatomic structure that mediates arousal. Neurons of the ascending reticular activating system are located in the midbrain, pons, and medulla, and control arousal from sleep. Metabolic conditions, likely hypoglycemia or hypoxia, can decrease acetylcholine synthesis in the central nervous system, which correlates with the severity of delirium.
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).
What are the three categories of altered mental status?
When a patient presents to the emergency department (ED) with altered mental status, three broad categories of diagnosis should be considered: delirium, coma, and dementia. 1 Altered mental status has many definitions, but fundamentally it involves changes in a person’s alertness, attention, memory, and/or awareness. 2.
How many people in the ED have altered mental status?
An estimated 2% of ED patients will present with altered mental status. Altered mental status will be present in 10% of hospitalized patients and 50% of hospitalized older adult patients. 15 More than 2.6 million older adults develop delirium each year, costing $164 billion in annual healthcare expenditures. 16
What is the definition of mental status?
Mental status, simply put, is how well one’s brain and body are working in sync. When a patient presents to the emergency department (ED) with altered mental status, three broad categories of diagnosis should be considered: delirium, coma, and dementia. 1 Altered mental status has many definitions, but fundamentally it involves changes in a person’s alertness, attention, memory, and/or awareness. 2
When managing acutely altered patients in the ED, the first priority should be deciphering “sick”?
If a patient has abnormal vital signs, act immediately to stabilize the patient. When managing acutely altered patients in the ED, the first priority should be deciphering “sick” or “not sick.” If the patient is critical, stabilize the patient before proceeding to imaging. The diagnosis often is not established until after multiple days of inpatient testing, monitoring, and therapeutic intervention.
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.
Is confusion a cause of altered mental status?
To date, an all-encompassing explanation of altered mental status does not exist. However, certain aspects have been studied. Neurobiology studies have shown that human attention is governed by the “non-dominant” parietal and frontal lobes. Thus, with confusion and inattention, there typically is some molecular, structural, chemical, or electrical dysfunction in these brain regions. 17
Causes of Recent AMS
Causes of recent AMS include primary central nervous system insults, systemic infections, metabolic disturbances, toxin exposure, medications, chronic systemic diseases, and psychiatric conditions ( Table 2).
Evaluation
Changes in consciousness, appearance, behavior, mood, affect, or motor activity are usually apparent by general observation and interaction with the patient.
Prevention
When patients are at risk of AMS, particularly for delirium, nonpharmacologic preventive measures can decrease incidence, especially in those who are hospitalized. 6, 9, 11 The use of multiple measures through a multidisciplinary team approach is most effective.
Treatment
Definitive therapy for AMS is treatment of the underlying causes or the removal of precipitating agents. However, when patients' behaviors threaten themselves or others before a reversible cause can be identified or fully treated, intervention is needed to avoid harm. In these situations, nonpharmacologic interventions are the treatment of choice.
