Alcohol or drug intoxication or withdrawal. A medical condition, such as a stroke, heart attack, worsening lung or liver disease, or an injury from a fall. Metabolic imbalances, such as low sodium or low calcium. Severe, chronic or terminal illness .
Delirium can last for a few days, weeks or even months but it may take longer for people with dementia to recover. In hospitals, approximately 20-30% of older people on medical wards will have delirium and up to 50% of people with dementia . Between 10-50% of people having surgery can develop delirium.
Usually, delirium gets better. In 6 out of 10 (60%) people, the symptoms disappear within six days. Others may continue to experience some symptoms for longer. About 1 in 20 (5%) people may still suffer from delirium more than a month after they first had symptoms.
In the long term, delirium can cause permanent damage to cognitive ability and is associated with an increase in long-term care admissions. It also leads to complications, such as pneumonia or blood clots that weaken patients and increase the chances that they will die within a year. “ Delirium is an emergency.
Help prevent medical problems by: Giving the person the proper medication on a regular schedule. Providing plenty of fluids and a healthy diet. Encouraging regular physical activity. Getting prompt treatment for potential problems, such as infections or metabolic imbalances.
Neuroleptics may be needed if the patient is having distressing hallucinations/delusions or. the patient is very agitated. High potency with low anticholinergic activity. Low dose. Haloperidol or risperdone. Benzodiazepine if delirium is secondary to benzo or alcohol withdrawal.
Treatment for delirium depends on the cause. Treatments may include: Antibiotics for infections. Fluids and electrolytes for dehydration. Antipsychotic drugs include: Haloperidol (Haldol®). Risperidone (Risperdal®). Olanzapine (Zyprexa®). Quetiapine (Seroquel®).
Patients at the end of life develop a number of distressing symptoms . Although delirium is one of the most common neuropsychiatric problems in patients with advanced cancer, it is poorly recognised and poorly treated. Delirium is prevalent at the end of life , particularly during the final 24–48 h.
How to Help a Person with Delirium Encouraging them to rest and sleep. Keeping their room quiet and calm. Making sure they’re comfortable. Encouraging them to get up and sit in a chair during the day. Encouraging them to work with a physical or occupational therapist. Helping them eat and drink.
In contrast to dementia , delirium is typically conceptualized as a reversible process. Delirium is frequently reversible even in patients with advanced illness. However, delirium may not be reversible in the last 24 to 48 hours of life. This is most likely due to irreversible processes including multiple organ failure.
Even though patients who have had delirium may recover , they are still at higher risk of developing cognitive impairment and dementia in the future.
Overall, the most common causes of delirium are the following: Drugs , particularly drugs with anticholinergic effects, psychoactive drugs , and opioids. Dehydration. Infections , such as pneumonia, a bloodstream infection (sepsis), infections that affect the whole body or cause a fever, and urinary tract infections .
What I learned today: How to care for someone with delirium Surround them with familiar objects and people. A clock provides visual stimulus and helps them keep track. Speak in short, clear, simple sentences. Explain, explain, explain. Check that they’ve heard and understood. Answer each time as if it’s the first. Don’t talk over their head or pretend they’re not there.
The main symptoms of delirium tremens are nightmares, agitation, global confusion, disorientation, visual and auditory hallucinations, tactile hallucinations, fever, high blood pressure, heavy sweating, and other signs of autonomic hyperactivity (fast heart rate and high blood pressure).
Observational studies show that the most common drugs associated with delirium are sedative hypnotics ( benzodiazepines ), analgesics ( narcotics ), and medications with an anticholinergic effect. Other medications in toxic doses can also cause delirium.
