Things To Know About Delirium And What You Can Do

1.Delirium is extremely common in aging adults.

Almost a third of adults aged 65 and older experience delirium at some point during a hospitalization, with delirium being even more common in the intensive care unit, where its been found to affect 70% of patients. Delirium is also common in rehabilitation units, with one study finding that 16% of patients were experiencing delirium.

Delirium is less common in the outpatient setting . But it still can occur when an older adults gets sick or is affected by medications, especially if the person has a dementia such as Alzheimers.

What to do: Learn about delirium, so that you can help your parent reduce the risk, get help quickly if needed, and better understand what to expect if your parent does develop delirium. You should be especially be prepared to spot delirium if your parent or loved one is hospitalized, or has a dementia diagnosis. Dont assume this is a rare problem that probably wont affect your family. For more on hospital delirium, see Hospital Delirium: What to know & do.

2. Delirium can make a person quieter.

What to do: Be alert to those signs of difficulty focusing and worse-than-usual confusion, even if your parent seems quiet and isnt agitated. Tell the hospital staff if you think your parent may be having hypoactive delirium. In the hospital, its normal for older patients to be tired. Itsnotnormal for them to have a lot more difficulty than usual making sense of what you say to them.

Fda Approves New Medication For Alzheimer’s

In June 2021, the U.S. Food and Drug Administration approved Aduhelm for treating patients with Alzheimers disease. Aduhelm is the first new drug approved to treat the disease since 2003 as well as the first to specifically target amyloid-beta – the protein researchers widely believe to play a role in the development of Alzheimer’s.

Delirium: Delirium requires immediate treatment by a physician. Since it’s usually caused by a physical illness or infection, medications such as antibiotics often resolve the delirium.

What Is The Difference Between Dementia And Delirium

People suffering from dementia or delirium can present very similar symptoms, which is why the two conditions are often referred to in the same context. The two conditions are as a result of impaired cognitive function and in both cases the person will become confused and disoriented. But although there are many similarities between the two illnesses, there are also some important differences between dementia and delirium, so it can be helpful to gain a greater understanding of the two diseases.

Dementia is normally associated with old age, but although it typically afflicts the older generation, it is actually caused by a number of different degenerative brain diseases and symptoms of dementia can also develop as the result of a stroke or brain injury.

Delirium is a state of mental confusion usually caused by an acute illness or a toxic reaction to drugs. A good example of a delirious state is when a patient is suffering from a fever and begins to hallucinate.

The onset of the symptoms of dementia is usually fairly gradual, with the possible exception of dementia symptoms caused by a stroke, and in some cases the cognitive decline is so slow that the patient can continue to enjoy a productive life for many years. By contrast, the onset of the symptoms of delirium is rapid and they have a definite starting point.

What Are The Causes Of Delirium

What Is The Difference Between Delirium And Dementia ...

Delirium can be caused by changes in a person’s health, such as an infection or a medication change. It can also be caused by things such as constipation, dehydration and pain. Many people will have more than one problem leading to their delirium. Sometimes it is difficult to find the cause.

People with dementia, cognitive impairment, or hearing or vision loss are at an increased risk of delirium.

How Is Delirium Treated

The doctor may request blood and urine tests and will be able to decide on appropriate treatment. They may also want to review any medication that could be contributing to the delirium.

There is also evidence that delirium can be prevented by targeting potential causes. You can mitigate against some of the causes of the confusion, like constipation, dehydration and infection, by ensuring the person stays well hydrated, observes hand hygiene and follows any advice theyre given about wound care and medical devices . If possible, you should also avoid the person moving beds or wards in hospital.

Is Delirium The Same As Confusion

Dementia develops over time, with a slow progression of cognitive decline. Delirium occurs abruptly, and symptoms can fluctuate during the day. The hallmark separating delirium from underlying dementia is inattention. Often, persons with dementia develop delirium while hospitalized.

Likewise, what causes delirium? Delirium can be triggered by a serious medical illness such as an infection, certain medications, and other causes, such as drug withdrawal or intoxication. Older patients, over 65 years, are at highest risk for developing delirium. People with previous brain disease or brain damage are also at risk.

In respect to this, what causes sudden confusion and disorientation?

Two common causes of disorientation are delirium and dementia. Delirium is caused by sudden abnormal brain functioning. Something as simple as a change in surroundings can also trigger delirium. For example, some adults may experience hospital delirium after surgery, or after being in intensive care.

Does delirium fluctuate?

Fluctuation. The appearance of delirium symptoms can fluctuate significantly and frequently throughout the day. While people with dementia have better and worse times of day, their memory and thinking skills stay at a fairly constant level during the course of a day.

  • problems with perception
  • having hallucinations or delusions
  • alternatively, being quiet, drowsy and lethargic

HPMQ – Dementia vs. Delirium

Individuals can also experience both types of delirium together. Symptoms of delirium usually improve in a few days to weeks, depending on any underlying medical conditions.

According to the Cleveland Clinic, delirium happens more often in older adults and hospitalized patients. Hospital delirium can affect 10% to 30% of those patients.

Additionally, those with high-risk health condition may develop delirium: 80% of people who are at end of life those who have had surgery 70% of those in intensive care 60% of people over age 75 in nursing homes 30% to 40% of those who have HIV and 25% of people with cancer.

It is sometimes difficult for health care providers to pinpoint the exact cause of the delirium. Some known causes are alcohol/drug toxicity reactions to pneumonia sepsis or urinary tract infections changes in environment dehydration medications thyroid issues hospitalization kidney or liver failure insomnia and pain.

A physician will look for changes in the individual to determine a diagnosis of delirium. An example of such changes is if someone is displaying noticeable changes in focus and has a rapid onset of thinking problems, which change during the course of the day. The physician will also perform a physical exam as well as blood and urine tests and possible imaging tests such as X-rays, CT or MRI scans.

What Causes Delirium In Hospitals

Delirium is more likely to develop when patients are in intensive care, heavily sedated, and on ventilators up to an 85% chance.

Its also common when patients are recovering from surgery and with something as simple as a urinary tract infection.

Unfortunately, once the delirium starts, it can last for months.

What Is Treatment And Support For Delirium

Delirium is treated first by addressing the medical problem that have caused it. For example, if the person has low blood oxygen or low blood sugar levels these will be corrected quickly. If the person has an infection they may be given antibiotics. If they are in pain, constipated or not passing urine then these will be treated. Doctors will also review the persons medication and stop any non-essential drugs that may be linked to delirium. Staff will make sure the person is supported to eat and drink regularly.Delirium will usually improve if its cause is found and treated.A supportive and calm environment can also help someone recover from delirium. Nursing staff, and visiting family and friends, can all help by:

Doctors wont normally give someone medication to treat delirium, because there is very little evidence that drugs help. Drugs should be considered only if the persons behaviour poses a risk of harm to themselves or others, or if hallucinations or delusions are causing the person severe distress. In either case a doctor may try a low dose of a sedative or an antipsychotic for a few days.

Delirium In People With Dementia

Distinguishing between delirium or dementia is important however, a more difficult task may be identifying delirium in someone who already has dementia. According to a study by Fick and Flanagan, approximately 22% of older adults in the community with dementia develop delirium. However, that rate skyrockets to 89% for those who have dementia and are hospitalized.

Knowing how to identify delirium in someone who is already confused is critical for appropriate treatment and a faster recovery. Delirium superimposed on someone with dementia also is connected with a more than double mortality risk compared to those with delirium or dementia alone.

Pearls And Other Issues

Dementia Vs Delirium / Understanding And Treating Delirium ...
  • The terms delirium and dementia are different entities yet are used interchangeably due to their overlapping features.
  • Delirium is an abrupt onset of reduced orientation to the environment in contrast to dementia, a gradual neurodegenerative process leading to the disturbance in the core features, and attention is affected much later in the disease course.
  • Some exceptions to point #2 are sudden-onset cognitive decline with vascular dementia and gradual onset delirium with chronic aspirin exposure.
  • Dementia is a precipitating factor for the development of delirium in elderly patients, and also delirium is an independent risk factor for the development of dementia.
  • Delirium can be preventable and reversible, whereas dementia is not reversible except in normal pressure hydrocephalus and in the case of pseudodementia resulting from B12 deficiency, thyroid disorders, syphilis, and depression.
  • Delirium can be superimposed on dementia due to multiple etiologies. Therefore it requires a thorough workup for the diagnosis.
  • Unlike delirium, patients with dementia tend to have a state of wakefulness, and the baseline deficits tend to be fixed.
  • Delirium can signify some serious underlying medical condition and can be fatal in the elderly population. Early recognition and risk stratification can help improve the outcome.

    What Side Effects Do Delirium Treatments Have

    Antipsychotic drugs come with some side effects, although researchers are working on developing drugs that cause fewer side effects. Side effects are more common in older adults and can include:

    • High illness and death rates.
    • Stroke.
    • High-than-normal pulse rate with irregular heartbeats .

    Benzodiazepines can cause:

    Dementia Delirium And Alzheimers Disease

      Understanding the differences between these terms can be considered a first step in understanding what may be going on with you, a family member, a friend, or colleague.

      Dementia is often incorrectly used as an interchangeable term for Alzheimers disease. Dementia is a generic term, rather like saying car or fever. What type of car? Why is there a fever?

      Dementia in simplest terms is a term used for a group of approximately 130 or more cognitive disorders. Those disorders can result in problems with: memory, judgment, using and understanding the language, problems and deficiencies in motor activity, and problems with recognizing objects and people. It can also include difficulty with executive function which is the ability to plan, organize and think in the abstract. These disorders are a result of the death of neurons or permanent damage to the neurons.

      Dementia is generally of a gradual onset. Unless the dementia is one of the types that can be reversed dementia is a progressive illness that, at this time has no known cure. There are treatments available to alleviate some of the symptoms for a certain time period, such as behavioral therapies, and medications. Alzheimers disease is the most common form of dementia.

      Obtaining an accurate diagnosis is critical to understanding the prognosis, obtaining treatment and planning for the future.

      • People who have had surgery.
      • 80% of people who are at the end of life.
      • 70% of people in intensive care units .

      Dr Jose R Maldonado: Delirium & Dementia, Two Sides of the Same Coin

      Itâs normal to feel scared or overwhelmed when you care for someone with delirium. Even things you do to help can upset them. It can also cause them to do things that are unsafe for you and them.

      It can be hard to know if or when delirium may cause someone to get aggressive. To keep your loved one from hurting themselves or others, take away or lock up anything in the home that could be used as a weapon. If they get physically violent, stop what youâre doing and back away. Call for help if you need to.

      Remember that delirium may cause a person to say or do things that are rude or hurtful, but itâs not something they can control.

      How Is Delirium Different From Dementia

      Delirium is different from dementia. But they have similar symptoms, such as confusion, agitation and delusions. If a person has these symptoms, it can be hard for healthcare professionals who dont know them to tell whether delirium or dementia is the cause. When a person with dementia also gets delirium they will have symptoms from both conditions at once.There are important differences between delirium and dementia. Delirium starts suddenly and symptoms often also vary a lot over the day. In contrast, the symptoms of dementia come on slowly, over months or even years. So if changes or symptoms start suddenly, this suggests that the person has delirium.Dementia with Lewy bodies is an exception. This type of dementia has many of the same symptoms as delirium and they can vary a lot over the day.

      Other symptoms of dementia

      Dementia can cause a number of different symptoms. Here we explain some of these changes and suggest practical ways to manage them.

      • taking multiple medications
      • having already had delirium in the past.

      Enhancing Healthcare Team Outcomes

      Delirium, dementia and depression: What is the difference ...

      Differentiating delirium and dementia is critically important and can be challenging in many cases. Delirium is a common occurrence in elderly patients and is often overlooked in the elderly due to concurrent history of dementia. The two are distinct pathologic processes with different management and prognoses. Delirium suggests serious medical issues and usually carries a poor prognosis.

      Interprofessional teamwork, including an emergency room provider, neurologist, neuropsychologist, geriatrician, and intensivist, is warranted. Besides, pharmacists, physical and occupational therapists, nursing, and case management staff also play a vital role. Pharmacists play an important role by providing us with important information about pharmacokinetics and potential drug interactions requiring frequent monitoring. Physical and occupational therapists help with mobility and structured activities to focus patients. The role of the nursing staff is pivotal in taking care of all the basic needs of demented patients. Social workers play a significant role by getting the providers in touch with their family and during transitions of care.

      Some of the barriers that may hinder clinical improvement are failing to distinguish the two early on or identifying superadded delirium in a demented patient. Therefore a holistic and integrated approach via an interprofessional team can lead to early recognition and risk stratification, improving patient outcomes.
