Dementia, Delirium & When to Seek Medical Care. Interview with Dr. Lisa Frank- Part 1 (Ep #028)
Dec 04, 2019
One of the most complicated situations families that I work with are faced with has to do with older adults with dementia developing a delirium.
Is the dementia worsening? Or is it a delirium? It's so hard to tell.
In this week’s episode, I am delighted to interview my best friend, Dr. Lisa Frank to talk with us about dementia, delirium, and when to seek medical care.
This is the first of a 3-part interview with Psychiatrist, Dr. Lisa Frank.
In this interview, Dr. Frank explains the difference between dementia and delirium and talks about the signs that you should be aware of that would indicate that your loved one needs medical care. She also gives an overview of what to expect in the Emergency Room with your loved one with dementia, who may also have delirium. And, we talk about the important role that families play.
Lisa Frank, MD is a board certified psychiatrist with special interests in geriatric psychiatry, trauma, and mood disorders. Dr. Frank has practiced in a variety of clinical settings, including inpatient psychiatry units, partial hospitalization programs, and outpatient. She has served as Medical Director for two acute psychiatric inpatient units and is a former faculty member of both Morehouse School of Medicine and Emory University School of Medicine, both in Atlanta, GA. Dr. Frank currently works in a community mental health care setting.

FAQs about Delirium
In addition to what is shared in the video, I wanted to share answers to some of the most frequently asked questions I get about delirium
What is delirium?
Delirium is an acute medical problem often resulting in changes in cognitive function and mentation (e.g., the way the brain thinks, remembers, processes information, etc). It can create problems in thinking and cause confusion.
For example: An older adult who typically knows where they live and the day of the week may suddenly NOT know! Or, a person with dementia who is usually agreeable to receiving assistance from caregivers like with taking medications or bathing, may suddenly refuse care, and may even become agitated.
Delirium usually comes on very quickly. Like within hours or a few days.
What's the difference between dementia and delirium?
Sometimes it can be hard to tell the difference between dementia and delirium because so many of the symptoms overlap.
One of the distinguishing characteristics of delirium is that the onset of symptoms is sudden and is very different from how the person with dementia typically is.
Dementia, on the other hand, is a chronic degenerative illness, meaning that the decline in cognitive function and ability typically happens slowly over time.
Because symptoms of delirium and dementia can be similar, so much so that even doctors don't even get it right, it's essential that you help your aging parents communicate with their doctors by sharing what your loved one is like at baseline (what they typically look like with dementia) and how the current symptoms you are noticing are different. This will give the doctor clues about the need to evaluate for delirium. Your participation is essential in helping doctors to make an accurate diagnosis.
What are the common signs and symptoms of delirium in older adults?
There are many signs and symptoms of delirium and to complicate matters, they can change throughout the day (palm to forehead). For example, there may be times, like mid-morning where your loved one seems typical and then in the evening, symptoms worsen. Symptoms tend to be worse during the evening and nighttime when it's dark and things look less familiar.
And, here's where things get even more complicated! Say your loved one at baseline experiences "sundowning" and then they have a delirium on top of it and their sundowning seems worse. In this case, it can be really hard to tell if it's sundowning or if there is a medical change- like delirium, leaving you in a real bind!
Here's where knowing your loved one's typical presentation with dementia AND knowing the signs and symptoms of delirium are really important (the information below is an excerpt from the Mayo Clinic website description of Delirium*- it's really good so here you go)
Reduced awareness of the environment
This may result in:
An inability to stay focused on a topic or to switch topics
Getting stuck on an idea rather than responding to questions or conversation
Being easily distracted by unimportant things
Being withdrawn, with little or no activity or little response to the environment
Poor thinking skills (cognitive impairment)
This may appear as:
Poor memory, particularly of recent events
Disorientation — for example, not knowing where you are or who you are
Difficulty speaking or recalling words
Rambling or nonsense speech
Trouble understanding speech
Difficulty reading or writing
These may include:
Seeing things that don't exist (hallucinations)
Restlessness, agitation or combative behavior
Calling out, moaning or making other sounds
Being quiet and withdrawn — especially in older adults
Slowed movement or lethargy
Disturbed sleep habits
Reversal of night-day sleep-wake cycle
These may appear as:
Anxiety, fear or paranoia
Irritability or anger
A sense of feeling elated (euphoria)
Rapid and unpredictable mood shifts
What are the common causes of delirium in older adults?
It is quite possible for a person to have more than one cause for delirium.
For example: I commonly see older adults with both dehydration and urinary tract infections (UTIs). And this makes sense! If we are dehydrated, we are more likely to develop a urinary tract infection. Then, add on new medications, and the person might have dehydration, a UTI and a medication that they are not tolerating well, or that is interacting with another medication.
In some cases, your loved one may even be hospitalized, being treated for a delirium, but doctors may struggle to pinpoint a cause.
Here's an overview* of common causes of delirium:
Certain medications or drug toxicity
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
Fever and acute infection, particularly in children
Urinary tract infection, pneumonia or the flu, especially in older adults
Exposure to a toxin, such as carbon monoxide, cyanide or other poisons
Malnutrition or dehydration
Sleep deprivation or severe emotional distress
Surgery or other medical procedures that include anesthesia
Why are older adults more likely to get delirium?
Delirium is more common in older adults! And here's why! Simply put, older adults are at risk of delirium due to a decreased cognitive reserve, meaning the brain has less ability to compensate to physiological changes as we get older. But, not only does the brain have less reserve as we age, the same is true for our organs. So, when there are changes to an older adult's physiology (like dehydration, a virus, or an infection), the older body is very sensitive to these changes and becomes more vulnerable to delirium.
This is why if you're caring for aging parents, you should be aware of some of the signs and symptoms, as well as some of the common causes, so that you know how to prevent a delirium from happening in the first place. Helping your loved one to stay well-nourished, for example, is a great prevention strategy! (Easier said than done- am I right?)
Delirium is also more common under the following situations that disproportionately affect older adults:
When a person is in the hospital, especially while they are in the Intensive Care Unit (ICU)
When a person is recovering from surgery where general anesthesia is used
When a person is living in a nursing home or skilled nursing facility
Brain disorders such as dementia, stroke or Parkinson's disease
When a person has had delirium episodes in the past, they are more vulnerable to them again
When a person has visual or hearing impairment
When a person has multiple medical problems
Why are people with dementia more likely to get delirium?
Having dementia actually puts folks at greater risk of developing delirium. And this makes sense! Dementia is a medical condition in the brain. The brain is already compromised, so when there is another issue in the body (like pain or metabolic imbalances) the brain will have a harder time coping and will be more vulnerable to a delirium. Plus, people with dementia may have difficulty communicating when they are in pain or experiencing discomfort, even stating when they are thirsty or hungry, and as a result, a problem may start without any warning.
How can I prevent delirium in my aging parents?
Delirium is hard on the brain and can create lasting changes in older adults AND people with dementia, so prevention is key! Here are some tips for preventing delirium:
Promote good sleep habits
Help your loved one remain calm and well-oriented
Help prevent medical problems or other complications by following medical recommendations for managing chronic conditions, like diabetes, heart disease, COPD, etc.
Help your loved one stay hydrated and nourished.
Help you loved experience a good quality of life, like having sunlight and fresh air, activities. Even a schedule can help.
Why is it so important that I get my loved one to a doctor if they have delirium?
Delirium is a medical emergency and it is critical that you get your loved one medically evaluated and treated! Early diagnosis and treatment of delirium is essential! Here's why!
The longer the person lives with an untreated delirium, the sicker they will get. Delirium also increases risk of death.
The longer a person lives with untreated delirium, their health may experience lasting negative changes, even after the delirium gets treated.
The longer an older adult lives with an untreated delirium, the greater their risk of developing dementia.
The longer an older adult lives with an untreated delirium, the more likely they are to move to a skilled nursing facility or nursing home.
The longer an older adult lives with an untreated delirium, the more medical treatment they will need and the more costly the care becomes.
The longer an older adult lives with an untreated delirium, the greater the caregiver burden!
