Delirium is a state of acute confusion and altered mental status that can occur due to various underlying causes. Identifying and managing the underlying cause is crucial in the Management of Delirium. Here are some common causes of delirium and possible management strategies:
- Medications:
- Management: Review and adjust medications, discontinue or replace medications causing delirium, and monitor for improvement.
- Infections (e.g., urinary tract infections, pneumonia):
- Management: Treat the underlying infection with appropriate antibiotics, ensure adequate hydration, and provide supportive care.
- Metabolic disturbances (e.g., electrolyte imbalances, hypoglycemia, liver or kidney dysfunction):
- Management: Correct the underlying metabolic abnormalities, restore electrolyte balance, and manage organ dysfunction as appropriate.
- Substance withdrawal or intoxication:
- Management: Provide supportive care, manage withdrawal symptoms, ensure a safe environment, and consider referral for substance abuse treatment if needed.
- Sleep deprivation:
- Management: Optimize sleep hygiene, provide a quiet and comfortable environment, and promote a regular sleep-wake cycle.
- Acute neurological conditions (e.g., stroke, head injury, seizures):
- Management: Treat the underlying neurological condition, provide supportive care, and involve specialists as necessary.
- Hypoxia (inadequate oxygen supply):
- Management: Identify and correct the underlying cause of hypoxia, ensure adequate oxygenation, and monitor for improvement.
- Acute pain or discomfort:
- Management: Assess and manage pain or discomfort appropriately, consider non-pharmacological approaches, and provide analgesics as needed.
- Psychological stress or emotional distress:
- Management: Provide reassurance and emotional support, address underlying stressors if possible, involve mental health professionals if needed.
- Surgical procedures or anesthesia:
- Management: Optimize postoperative care, manage pain and discomfort, ensure proper hydration and nutrition, and monitor for resolution of delirium.
It is important to note that the management of delirium should be individualized based on the underlying cause and the patient’s specific needs. Prompt recognition and treatment of the underlying cause, along with supportive care, are key elements in the management of delirium. Consulting with a healthcare professional is advised for an accurate diagnosis and appropriate management plan.

Types of Delirium
There are different types of delirium based on the cause or contributing factors. Here are some of the common types:
- Hyperactive Delirium: In hyperactive delirium, individuals may appear agitated, restless, or hyperactive. They may exhibit behaviors such as irritability, hallucinations, delusions, and restlessness. This type of delirium is more noticeable and easier to identify.
- Hypoactive Delirium: Hypoactive delirium is characterized by a decrease in motor activity and responsiveness. Individuals may appear lethargic, withdrawn, or apathetic. They may have slowed speech, decreased movement, and decreased alertness. Hypoactive delirium can be easily overlooked or mistaken for depression or other conditions.
- Mixed Delirium: Mixed delirium refers to a combination of hyperactive and hypoactive features. Individuals may exhibit periods of agitation and restlessness followed by periods of lethargy and decreased activity. The symptoms can fluctuate rapidly and unpredictably.
- Medication-Induced Delirium: Certain medications, especially those with psychoactive properties, can induce delirium as a side effect. These may include sedatives, anticholinergic drugs, opioids, benzodiazepines, and some antiepileptic medications. Delirium caused by medication may present with any combination of hyperactive, hypoactive, or mixed features.
- Withdrawal Delirium: Delirium can occur during the withdrawal phase of substance abuse, particularly with alcohol, benzodiazepines, and barbiturates. Symptoms can include tremors, anxiety, confusion, hallucinations, and autonomic hyperactivity.
- Postoperative Delirium: Postoperative delirium can occur after surgery, especially in older adults. Factors such as anesthesia, pain medications, sleep disruption, and underlying medical conditions can contribute to the development of delirium in the postoperative period.
- Delirium due to Medical Conditions: Delirium can be a result of various medical conditions, such as infections (e.g., urinary tract infections, pneumonia), metabolic disturbances (e.g., electrolyte imbalances, liver or kidney failure), neurological disorders (e.g., stroke, brain tumors), and systemic illnesses (e.g., sepsis, organ failure).
It’s important to note that these types of delirium are not mutually exclusive, and an individual can exhibit symptoms from more than one type simultaneously. The specific type and presentation of delirium may vary depending on the underlying cause, individual characteristics, and other contributing factors.
Terminal Delirium near the end of life
Terminal delirium, also known as agitation at the end of life or terminal restlessness, is a condition that can occur in individuals who are in the final stages of a life-limiting illness. It is characterized by acute confusion, restlessness, and agitation. Terminal Delirium can be distressing for both the individual experiencing it and their loved ones.
Here are some key points to understand about terminal delirium:
- Causes: The exact cause of terminal delirium is not fully understood, but it is believed to be a result of multiple factors. These factors may include metabolic imbalances, medication side effects, underlying disease processes, infections, organ failure, and inadequate pain or symptom management.
- Symptoms: Terminal delirium can manifest in various ways. Common symptoms include confusion, disorientation, restlessness, agitation, hallucinations, delusions, rapid mood swings, incoherent speech, and altered sleep patterns. It is important to note that each individual may experience a unique combination of symptoms.
- Duration: Terminal delirium is typically a transient condition and may last for hours to days. However, it can be distressing for the individual and their loved ones, as the person may be unable to communicate their needs or express their discomfort effectively.
- Management: Managing terminal delirium requires a holistic approach. It involves addressing the underlying causes, providing supportive care, and ensuring comfort. Pain and other distressing symptoms should be managed effectively. Medications such as antipsychotics, sedatives, and opioids may be prescribed to alleviate agitation and promote calmness. Non-pharmacological interventions, such as creating a calm and familiar environment, providing reassurance, and facilitating presence of loved ones, can also help manage delirium.
- Communication and support: Although the individual experiencing terminal delirium may have difficulty communicating verbally, it is important to continue providing emotional support and reassurance. Being present and maintaining a calm presence can help reduce distress. Communication through touch, gentle gestures, and maintaining a soothing environment can be beneficial.
- Emotional impact: Terminal delirium can be emotionally challenging for both the individual and their loved ones. It is essential to seek support from healthcare professionals, hospice or palliative care teams, counselors, or support groups. These resources can provide guidance, comfort, and assistance in coping with the situation.
It’s worth noting that terminal delirium is a complex condition, and its management may vary depending on the specific circumstances and individual needs. Healthcare professionals with expertise in palliative care can provide the most appropriate guidance and support during this time.
Delirium Symptom Management
Symptom management of delirium involves addressing the underlying causes and providing supportive care to minimize distress and maximize the patient’s comfort. Delirium is a state of acute confusion and altered mental function, often resulting from an underlying medical condition, medication side effects, or drug or alcohol withdrawal. Here are some approaches to symptom management:
- Identify and treat the underlying cause: The first step is to identify and address the root cause of delirium. This may involve conducting diagnostic tests, reviewing medications, and treating infections, metabolic imbalances, or other medical conditions.
- Environment modification: Create a calm and quiet environment for the patient. Minimize noise, bright lights, and other sources of sensory overload. Orient the patient to their surroundings and maintain a consistent daily routine.
- Reassurance and emotional support: Patients with delirium often feel anxious, agitated, or disoriented. Provide reassurance, calm communication, and emotional support to help reduce their distress. Maintain a reassuring presence and offer comfort measures.
- Medication review: Review the patient’s medications to identify any potentially causative or exacerbating drugs. Adjustments may be necessary, such as reducing dosages or discontinuing medications that may contribute to delirium.
- Symptom-specific interventions: Treat specific symptoms associated with delirium. For example:
- Agitation or restlessness: Non-pharmacological approaches like gentle reorientation, distraction, and relaxation techniques should be attempted first. If necessary, medications like low-dose antipsychotics may be used cautiously.
- Sleep disturbances: Promote a regular sleep-wake cycle, minimize disturbances during nighttime hours, and consider non-pharmacological sleep aids before resorting to medications.
- Pain management: Identify and manage any sources of pain, as uncontrolled pain can contribute to delirium. Use appropriate pain management strategies and consider non-opioid analgesics when possible.
- Fluid and nutrition management: Ensure the patient remains adequately hydrated and nourished. Address any fluid or electrolyte imbalances and provide a well-balanced diet, taking into consideration any dietary restrictions or medical conditions.
- Mobilization and physical activity: Encourage early mobilization and engagement in physical activity as tolerated. This can help maintain muscle strength, prevent complications, and promote overall well-being.
- Family involvement and education: Involve the patient’s family or caregivers in the care process. Educate them about delirium, its causes, and symptom management strategies. Their understanding and support can help alleviate stress and contribute to a more positive patient experience.
It’s important to note that the management of delirium should always be done under the supervision of a healthcare professional who can evaluate the specific needs and circumstances of the individual patient.
