What Is Dementia-Associated Psychosis?

Greater than 2 million People have dementia-related psychosis. When you’ve got a cherished one who has dementia, you already know that it may be a scary situation — for each these going by way of it and for his or her caregivers. Once they should take care of psychotic episodes, too, it may be much more unnerving.

“But instead of thinking psychotic features as this taboo, icky subject, I just want people to understand that it’s a normal manifestation of these illnesses. An expected manifestation. A disease talking,” says Pierre N. Tariot, the director of the Banner Alzheimer’s Institute in Phoenix, AZ.

“Your loved one is not ‘crazy.’ They’re ill. Their brain isn’t functioning properly. And we can evaluate that, and we can help you understand that. And we can help relieve the distress — yours and your loved one’s.”

What It Is

To know dementia-related psychosis, it helps to interrupt down the terminology:

Some consultants now check with dementia as “neurocognitive disorder.” However medical doctors nonetheless use the phrase dementia. It is a broad time period that encompasses a variety of situations brought on by adjustments within the mind.


Alzheimer’s illness is, maybe, the best-known type of dementia. However there are others, together with:

  • Lewy physique dementia
  • Frontotemporal dementia
  • Vascular dementia

These situations embody a decline in pondering and problem-solving that always makes every day life and unbiased residing troublesome.

Frequent signs of dementia embody:

  • Reminiscence lapses (forgetting the identify of a cherished one, for instance)
  • A waning consideration span
  • A tough time speaking (utilizing uncommon phrases, for instance, to check with acquainted objects)

Broadly, psychosis is when an individual has hassle determining what’s actual and what’s not. Folks with psychosis might have delusions, like a agency, false perception that somebody’s attempting to kill them. They might even have hallucinations — seeing or listening to one thing or somebody that others do not.

“There’s a tremendous lack of understanding and knowledge about these terms,” says Gary Small, MD, the director of the UCLA Longevity Heart. “Those terms are scary. Dementia sounds pejorative. And a term like psychosis or psychotic is scary, too.

“What I attempt to do is clarify what these issues are, what these phenomena are, and attempt to assist them perceive it.”


As the term might suggest, people with dementia-related psychosis have the decline in thinking and problem-solving skills of dementia, as well as delusions or hallucinations of psychosis. (Delusions are more common.)

All of that can trigger other problems, like:

  • Apathy
  • Anxiety
  • Aggression
  • Sleeplessness
  • Agitation
  • Lack of inhibition



The first step in finding out if your loved one has dementia-related psychosis is making sure that a hallucination or delusion isn’t the result something else. A uterine tract infection, for example, can lead to hallucinations.

Diagnosing dementia-related psychosis is mainly about gathering information; ruling out other causes; and then observing, listening, and asking questions.

“What I do is, I by no means see [people] by themselves,” says George Grossberg, MD, the director of geriatric psychiatry at the Saint Louis University School of Medicine. “I all the time see them a minimum of with a number of — however a minimum of with one — private caregiver or care associate. Normally, it is a partner or an grownup little one.

“I ask them questions about what kinds of things they’re noticing with the loved ones with dementia.”


What might these questions be?

“I might say, ‘It’s been about 3 or 4 months since we’ve seen you and Mom. How are things going?

“‘Have you ever or she observed something uncommon or completely different?

“‘Has Mom maybe either heard or seen things or imagined things that you’re concerned about because you don’t see or hear or imagine them?’

“And that opens up variety of a complete space for them to speak.”

It’s not always easy. Those with dementia may hide their symptoms, for fear of the stigma that often comes with mental health problems. Others — nurses, doctors, professional caregivers — may not pick up on the signs for a variety of reasons. That makes observing, talking, and asking the right questions — for everyone involved — even more important.

“I inform all my trainees, the medical college students and residents, ‘That is detective work,'” says Zahinoor Ismail, MD, the principal investigator at the Ron and Rene Ward Centre for Healthy Brain Aging Research at the University of Calgary.

“You need to look, and also you really should ask for data from all of the sources.”


There is not any treatment for Alzheimer’s and different dementias. So the primary line of therapy for dementia-related psychosis is not medicine or medication.

Actually, typically folks with milder psychosis might not want therapy. If a hallucination or a delusion would not hassle the particular person with dementia, there’s usually no have to deal with it. If it does hassle them, some easy strategies — like ensuring that the surroundings across the particular person with dementia would not set off the episode — will help.

Tariot recalls a woman with dementia who believed someone was in the room with her. In fact, the woman had caught a glimpse of her own reflection. Covering up a mirror lessened her anxieties. In another case where a person thought someone was spying on them, Small says lowering a window shade eased the trouble.

Also effective for some with dementia: Just getting their minds off an episode that may upset them.

“One of the best ways to reply is in a relaxed means, to distract folks,” Small says. “I usually remind them about what it was like when their children have been rambunctious and younger. You’d redirect them, with a sport to play, or so forth and so forth.”


If those kinds of methods don’t work, doctors may opt to prescribe medication. The FDA hasn’t approved any drugs specifically for dementia-related psychosis. Instead, doctors often go “off-label” to prescribe antipsychotic medicines that aren’t specifically for dementia-related psychosis.

“The place [methods that involve drugs] do not work, we do resort to medicines. The issue is the medicines we have had accessible … they only do not work very nicely,” Tariot says. “They’ve, at greatest, a few 1-in-5 probability of serving to sufficient to note, and about an 80 or 90 p.c probability of inflicting hurt.”

Psychosis with dementia can be challenging to diagnose and to treat. But understanding it, realizing its effects on both the person with dementia and those around that person, and using care and compassion in treating it can make things much better for everyone involved.

“I’ve folks ask me on a regular basis, ‘Gee, Dr. Grossberg, I do know you focus on Alzheimer’s illness. How do you do it? Do not you get depressed? Do not you get despondent?'” Grossberg says.

“And I say, ‘No. Simply the other.’ There’s quite a bit that we will do to essentially enhance the standard of life for the [person] and the care companions, to essentially make no matter remaining days they’ve left extra nice and extra comfy. That provides me quite a lot of satisfaction.”
