Definition of Delirium
Delirium refers to a sudden and severe disturbance in mental abilities, which include perception, attention, memory, thinking, and consciousness. It is classified as a mental disorder and is often characterized by confusion, disorientation, and a rapid onset of symptoms. Delirium is typically a temporary condition that arises due to an underlying medical condition, such as infection, drug intoxication, or withdrawal, and it generally resolves once the underlying cause is treated.
Symptoms of Delirium
The symptoms of delirium can vary widely depending on the underlying cause and individual factors. However, some common signs and symptoms include:
- Disturbances in consciousness, ranging from mild confusion to complete disorientation
- Fluctuations in alertness and attention, with periods of hyperactivity followed by extreme lethargy
- Impaired thinking and reasoning abilities, including difficulty organizing thoughts and solving problems
- Disrupted perception, such as hallucinations or illusions
- Emotional disturbances, including agitation, irritability, or depression
- Sleep disturbances, such as insomnia or excessive drowsiness
- Physical symptoms, such as tremors, sweating, or increased heart rate
Causes of Delirium
Delirium can be caused by various medical conditions, infections, and substances. Common causes include:
- Infections, such as urinary tract infections, pneumonia, or sepsis
- Drug or alcohol intoxication or withdrawal
- Metabolic imbalances, including electrolyte disturbances or liver or kidney failure
- Neurological disorders, such as strokes, brain tumors, or head injuries
- Severe pain or trauma
- Prolonged sleep deprivation or disrupted sleep patterns
Treatment of Delirium
The treatment of delirium involves addressing the underlying cause and providing supportive care to manage symptoms. Depending on the situation and severity, treatment may include:
- Identifying and treating the underlying medical condition, such as infections or metabolic imbalances
- Adjusting medications that may be contributing to delirium

It is crucial to promptly diagnose and treat delirium to prevent complications and ensure a full recovery.
