Types of Altered Mental Status
Altered mental status can manifest in different ways, with three main types recognized in medical practice: delirium, dementia, and psychosis.
Delirium: Delirium is a sudden change in mental function and is considered a medical emergency. People with delirium may experience disorientation, distraction, and exhibit unusual behaviors. It is a reversible condition and often occurs as a result of an underlying illness or medication side effects.
Dementia: Dementia is a progressive disorder that causes a decline in mental function, primarily affecting older adults. It leads to difficulties in daily life, including memory loss, trouble thinking, and changes in behavior. In advanced stages, individuals may lose awareness of their identity and surroundings.
Psychosis: Psychosis is a temporary condition where a person loses touch with reality. It can be caused by a medical condition, such as a brain tumor or infection, or as a side effect of certain medications. People experiencing psychosis may have disturbing thoughts, and they may see or hear things that are not real.

Causes of Altered Mental Status
Altered mental status can be caused by a range of factors, including central nervous system issues, adverse reactions to prescription drugs, infections, and various other causes. The brain is a complex organ, and any disruption in its normal functioning can result in changes in mental function and behavior. Let’s take a closer look at some of the main causes of altered mental status:
Central Nervous System Issues
The central nervous system, which includes the brain and spinal cord, plays a crucial role in our mental function. Any problems or disorders affecting this system can lead to altered mental status. Conditions such as brain hemorrhages, brain tumors, hepatic encephalopathy, obstructive hydrocephalus, seizures, and strokes can all cause changes in awareness, cognition, and behavior.
Adverse Reactions to Prescription Drugs
Sometimes, altered mental status can occur as a side effect of certain prescription medications. Drugs like antiseizure medications, corticosteroids, sedatives, and sleeping pills have been known to cause cognitive impairment, confusion, and other mental changes in some individuals. It’s important to closely monitor the use of these medications and consult a healthcare professional if any abnormal mental symptoms arise.
Infections can also contribute to altered mental status. Certain infections, such as meningitis, pneumonia, and urinary tract infections, can affect the brain and nervous system, leading to symptoms like confusion, delirium, and disorientation. It’s crucial to seek prompt medical attention if you suspect an infection may be causing changes in mental function.
In addition to central nervous system issues, adverse drug reactions, and infections, there are numerous other factors that can contribute to altered mental status. Metabolic disorders like dehydration, hypoglycemia, hyponatremia, hypothermia, hypothyroidism, and hypoxemia can all affect brain function and lead to changes in mental status. Traumatic brain injuries, drug overdoses or withdrawals, and shock are also known to cause alterations in consciousness and cognition.
It’s essential to remember that altered mental status is a symptom of an underlying condition, rather than a specific disease in itself. Identifying and addressing the root cause is crucial for effective diagnosis and treatment.

Common Symptoms of Altered Mental Status
Altered mental status can present with a wide range of symptoms, such as altered consciousness, confusion, hallucinations, and mood and mental health issues. These symptoms can vary in severity and may be indicative of different types of altered mental status.
Altered consciousness is a common symptom, which may include being in a coma or experiencing a state of reduced awareness. Confusion is another hallmark symptom, with individuals experiencing difficulty thinking clearly and being disoriented in time and place. Memory problems, including forgetfulness and amnesia, may also occur, affecting an individual’s ability to recall information and events.
Hallucinations, both visual and auditory, are another potential symptom of altered mental status. Individuals may perceive sights or sounds that are not actually present, which can be distressing and disorienting. Delusions, or strongly-held beliefs that are not based in reality, may also be present, further contributing to the altered mental state.
Other Symptoms and Mood and Mental Health Issues
In addition to the aforementioned symptoms, altered mental status can also manifest as slow responses to questions or stimuli, incoherent or nonsensical speech, and mood and mental health issues. Mood disturbances may include agitation, irritability, anxiety, depression, emotional outbursts, euphoria, and social withdrawal. These changes in behavior and emotions can significantly impact an individual’s daily functioning and quality of life.
It is important to note that the presence of these symptoms does not necessarily indicate a specific underlying cause of altered mental status. The diagnostic process involves a comprehensive evaluation to determine the underlying cause and appropriate treatment.

Understanding and recognizing these symptoms is crucial in identifying and addressing altered mental status. If you or someone you know experiences any of these symptoms, it is important to seek medical attention for a proper diagnosis and appropriate treatment.
Diagnosing Altered Mental Status
Diagnosing altered mental status involves a thorough evaluation that includes reviewing the individual’s medical history, conducting a physical examination, and, in some cases, ordering additional tests. The goal of this process is to determine the underlying cause of the changes in mental function and develop an appropriate treatment plan.
During the evaluation, healthcare providers will typically start by asking the patient (or their loved ones) about their medical history, including any pre-existing conditions, medications they are taking, and any recent changes in their health. This information helps provide important clues about potential underlying causes of the altered mental status.
Next, a comprehensive physical examination is conducted to assess the patient’s overall health and look for any signs of underlying medical conditions that may be contributing to the altered mental status. The examination may include assessing the patient’s airway, breathing, circulation, and neurologic function.
In some cases, additional tests may be necessary to further evaluate the individual’s condition. These tests can include blood tests to check for infections, metabolic imbalances, and other abnormalities, as well as imaging studies such as CT scans or MRI scans to assess the brain for any structural abnormalities or signs of injury. If a specific cause is suspected, specialized tests may be ordered, such as EEG (electroencephalogram) to evaluate brain activity or lumbar puncture to analyze the cerebrospinal fluid.

A comprehensive evaluation that includes a thorough review of medical history, physical examination, and appropriate testing is essential for accurately diagnosing the underlying cause of altered mental status. This information is crucial for developing an effective treatment plan and providing the best possible care for individuals experiencing changes in mental function.
Management and Treatment of Altered Mental Status
The management and treatment of altered mental status depend on the underlying cause and may involve the administration of antibiotics, changes in medications, intravenous fluids, surgical interventions, or the use of supplemental oxygen. The goal is to address the specific factors contributing to the altered mental state and provide appropriate care to improve the individual’s condition.
If the altered mental status is caused by an infection, such as meningitis or pneumonia, antibiotics may be prescribed to target the underlying bacterial or fungal pathogens. These medications help combat the infection and reduce inflammation in the brain, restoring normal mental function.
Changes in Medications
In some cases, altered mental status may be a result of adverse reactions to certain medications. If this is the case, healthcare professionals may recommend adjusting or changing the medications being taken. This can help alleviate the symptoms and restore mental clarity.
In situations where the altered mental status is due to dehydration or electrolyte imbalances, intravenous fluids may be administered. This helps restore proper hydration and electrolyte levels, which can improve brain function and alleviate confusion or disorientation.
In certain cases, altered mental status may be caused by conditions that require surgical intervention, such as brain hemorrhage or obstruction leading to increased intracranial pressure. Surgery may be performed to remove the hemorrhage or relieve the pressure on the brain, allowing for the restoration of normal mental function.
If the altered mental status is due to low levels of oxygen in the blood (hypoxemia), supplemental oxygen may be provided. This helps increase oxygen levels in the body, improving brain function and cognition.
It is important to note that the specific management and treatment approach for altered mental status will vary depending on the individual’s unique circumstances and the underlying cause of the condition. Therefore, it is crucial to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan.
