Medications Under Consideration For Fda Approval For Hallucinations

Dementia Caregiving Hallucinations or Delusions

To date, there is no medication that has FDA approval to help against hallucinations and delusions in Alzheimers patients. In the last year, Pimavanserin completed Phase 3 clinical trials and applied for FDA approval. Nuplazid is already FDA approved for Parkinsons disease to help with symptoms of hallucinations and delusions. Nuplazid is different from what is currently available by the way it functions and its side effects. This medication targets a specific serotonin receptor in the brain that causes a chemical reaction and reduces delusions and hallucinations. Additionally, scientists are also proving that by affecting serotonin receptor 5-HT2A, amyloid-beta levels decrease. Amyloid-beta proteins form clumps in the brain of Alzheimers patients causing brain cells to die.

When will Pimavanserin be on the market? It is estimated as early as August 2022 Pimavanserin could be FDA approved for hallucination and delusions in Alzheimers patients. This is dependent on its clinical trials proving its effectiveness. It was denied approval for Alzheimers use in 2021 because the FDA said the clinical trials didnt back up the claim of its medical benefit. The company resubmitted the drug application and its clinical trials and the FDA agreed to review all the data again and make a new decision in the beginning of August.

Stage : Moderately Severe Dementia

When the patient begins to forget the names of their children, spouse, or primary caregivers, they are most likely entering stage 6 of dementia and will need full time care. In the sixth stage, patients are generally unaware of their surroundings, cannot recall recent events, and have skewed memories of their personal past. Caregivers and loved ones should watch for:

  • Delusional behavior

Is It Really A Hallucination

First make sure that what youre dealing with is a hallucination caused by dementia and not simply the result of:

Eye sight problems

Dementia can affect sight and vision in many different ways. For example, a person with dementia might mistake a reflection in the mirror for an intruder or think people on TV are in the room with them. They could also have problems recognising familiar faces or become wary of familiar environments, for example, a shiny floor might look wet, a shadow in a corner might look like a hole.So before assuming theyre having a hallucination, arrange a sight test with an optician and make sure each room in the home is well lit and dementia friendly.

Other health issues

A kidney or bladder infection, alcohol, and certain medications can also cause confusion and lead to hallucinations.

Common Types Of Hallucinations

About 20 percent to 40 percent of people with PD have experienced hallucinations or delusions . Fortunately, not all hallucinations are scary or disturbing. Sometimes, they can be hardly noticeable, like for one member who wrote, I have infrequent hallucinations that are shadows in my peripheral vision. They startle me. But I can live with them if they dont get worse.

Lewy bodies can cause visual hallucinations of strange shapes, animals, or people. In addition, you may smell, hear, or feel things that are not there. For example, one member said, About a year ago, I could smell bacon cooking. We do not have bacon in the house. It finally went away.

Hallucinations may even be pleasant, like for one member who described her first experience. In my living room, I saw a little boy covered in fur. It lasted a good eight seconds, vivid and defined. I wasnt startled, just curious. I absolutely believed it was real until it vanished. My neurologist asked, Did it frighten you? and I replied, No, in fact, I wish the little furry boy would return!

Hallucinations are a sign of potential worsening symptoms of Parkinsons and should not be encouraged, even if they seem like a positive experience. Let your doctor know right away if you start to see or hear things that are not there.

Antipsychotics And Increased Risk Of Mortality For Elderly Patients With Dementia

Why people with dementia don

Available antipsychotics are used off-label to treat hallucinations, delusions, aggression, and agitation in patients with dementia.31,32,36 As noted previously, no antipsychotic medications are currently approved for the treatment of dementia-related psychosis, and all antipsychotics carry a Boxed Warning indicating that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.30 The US Food and Drug Administration conducted an analysis of 17 placebo-controlled trials that demonstrated an approximate 1.6- to 1.7-fold increase in mortality with the use of atypical antipsychotics by elderly patients with dementia-related psychosis compared to placebo-treated patients.30 The majority of the deaths appeared to be either cardiovascular or infectious in nature.30

In What Stage Of Dementia Are Hallucinations And Delusions Most Likely To Occur

The type of dementia most associated with hallucinations is Lewy body dementia. This affects about 1.4 million people in the U.S. and is the third-most-common type of dementia . People with Lewy body dementia will often see colorful people or animals that arent actually present, often for a few minutes at a time. This is more likely to occur in the early stages of the disease than later. People with Lewy body dementia often have hallucinations early and then, as they enter the middle stages, the hallucinations will go away completely as other symptoms, like problems walking, get worse.

People with Alzheimers disease have been shown to sometimes have hallucinations, as with patients of Parkinsons disease with dementia. This is rarer, however, and delusions are much more common with these illnesses. Both hallucinations and delusions in people with Alzheimers often occur in the late-middle to later stages of the disease.

Ways To Respond When Someone Is Experiencing Dementia Hallucinations

1. Determine if a response is neededThe first step is to determine whether the hallucination is bothering your older adult.

If its pleasant, you might not want to respond or call attention to it.

Just know and accept that its a dementia symptom and thankfully isnt causing distress.

If the hallucination is upsetting them or causing them to do something unsafe, then its time to quickly step in to provide comfort or redirect to a safe activity.

2. Stay calm and dont argue or try to convince using logicWhen someone is having a dementia hallucination, its important to stay calm and avoid contradicting them.

What theyre seeing is a dementia symptom and is very real to them.

Trying to explain that it isnt real simply wont work because of the damage that dementia has caused in their brain.

In fact, knowing that you dont believe them might make them even more upset and agitated.

If theyre calm enough to explain, it may also help to understand what theyre seeing. Listen carefully and try to pick up clues to what theyre seeing.

But keep in mind that dementia damage in the brain may affect their ability to use the correct words. For example, they could unintentionally say cabbages when they mean green cushions.

3. Validate their feelings and provide reassuranceBe careful not to dismiss your older adults experience.

Brushing off what theyre seeing by saying something like, Dont be silly, theres nothing there, is likely to upset them.

When This Happens What Do We Do

Hallucinations and delusions in patients with dementia

If you are a caregiver and your loved one is seeing bugs that you do not see, or accusing you of stealing something, it is human nature to respond with What bugs? or I didnt steal anything. Remember though, that your loved ones behaviors are likely coming from changes in the brain related to the Alzheimers or dementia. Becoming dismissive, defensive or arguing your point will not be effective.

Measurement Of Chat Ache And Bche

ChAT activity was assayed using an assay designed by Dr. Darreh-Shoris group at the Karolinska Institutet, as previously described in detail . The assay was performed on 384-well plates. The wells were coated overnight at 4°C with 100l of monoclonal anti-ChAT diluted 1:250 in 1× coating buffer per well except for wells which would later be used for the choline standards. After 5 washes with TBS, the samples , standards and blanks were loaded. Samples were denatured by incubation at 99°C for 3×8min 30s in a PCR machine. Ten microlitres of each sample was loaded in triplicate. Blanks consisted of dilution buffer alone. The reference standard for ChAT concentration was a pooled brain homogenate which had been prepared with 10× vol of each buffer. There were 7×2-fold dilutions of the pooled homogenate, starting with a dilution of 1:2. The choline standards for ChAT activity consisted of 8×2-fold dilutions of choline, with choline standard C1=50M. Fifty microlitres of each choline standard was loaded in triplicate. Forty microlitres of cocktail A was added to each sample/pooled homogenate/blank well. cocktail A was prepared as 4× of final concentrations and contained 10M choline chloride, 50M acetyl-CoA, 7mM acetyl phosphate and 1 unit/ml phosphoacetyltransferase in TBS buffer.

Supporting A Person Who Is Experiencing Hallucinations

If the person you care for regularly hallucinates, make an appointment for them to see their GP.

Make sure the person has regular medication reviews with a pharmacist or GP as new medications, or the combination of their medications, can be a cause of hallucinations. See further down this page for a list of information to take when you visit the GP.

Stage : Mild Cognitive Impairment

Clear cognitive problems begin to manifest in stage 3. A few signs of stage 3 dementia include:

  • Getting lost easily
  • Noticeably poor performance at work
  • Forgetting the names of family members and close friends
  • Difficulty retaining information read in a book or passage
  • Losing or misplacing important objects
  • Difficulty concentrating

Patients often start to experience mild to moderate anxiety as these symptoms increasingly interfere with day to day life. Patients who may be in this stage of dementia are encouraged to have a clinical interview with a clinician for proper diagnosis.

Coping With Hallucinations In Elderly Dementia Patients

Study results

When it comes to handling a seniors hallucinations, Marion Somers, Ph.D., author of Elder Care Made Easier: Doctor Marions 10 Steps to Help You Care for an Aging Loved One, suggests joining them in their version of reality. Ask the dementia patient about what they are experiencing as if it is real so you can more effectively defuse the situation. Refrain from trying to explain that what they are seeing or hearing is all in their head. Otherwise, youre going to aggravate them, and you dont want to increase the level of agitation, Somers advises.

Reassure them by validating their feelings. Say something like, I see that youre upset. I would be upset if I saw those things, too. Tell them that they are safe with you and you will do everything in your power to help them feel secure.

A comforting touch, such as gently patting their back, may help the person turn their attention to you and reduce the hallucination, according to the Alzheimers Association. You also can suggest that they move to a different room or take a walk to get away from whatever may have triggered the experience.

Hallucinations arent just a symptom of Alzheimers disease, either they are also very common in seniors with Lewy body dementia. Furthermore, poor eyesight, hearing loss, certain medications, dehydration and urinary tract infections can all contribute to hallucinations.

Signs And Symptoms Of Dementia With Lewy Bodies

Dementia with Lewy bodies can be confused with other forms of dementia, but it also has features of a psychiatric nature such as hallucinations and delirium.

The primary sign of DLB is a progressive decline in cognitive functions such as memory, thinking, and problem-solving. The decline in cognitive function is enough to affect your ability to work and perform normal daily activities. Although memory may be affected, it isn’t usually as impaired as in someone with Alzheimer’s disease .

DLB is generally diagnosed when at least two of the following features are also present with dementia:

  • Fluctuations in attention and alertness. These fluctuations may last for hours or days. Signs of these fluctuations include staring into space, lethargy, frequent drowsiness, and disorganized speech. These fluctuations have been referred to as “pseudodelirium,” because they are similar to delirium.
  • Visual hallucinations. These hallucinations recur and are very detailed. While the hallucinations may be upsetting to someone observing them, they generally don’t bother the person experiencing them. About 80 percent of people with DLB have visual hallucinations.
  • Movement symptoms consistent with PD. These movement symptoms include: slow movement, rigidity, and falls. Tremors may also be present, but not as pronounced as in a person with PD with dementia.

Additional signs and symptoms seen in DLB include:

The symptoms of DLB may resemble other conditions. Always see your doctor for a diagnosis.

Making Sense Of The Science

PD and LBD often occur simultaneously, leading some members of the medical community to consider Parkinsons as part of a group of similar diseases that fall under the umbrella of Lewy body disorders. Technically, Lewy bodies are clumps of alpha-synuclein proteins that can accumulate in various parts of the brain and brain stem.

The location of Lewy bodies determines how they may affect the body, for example:

  • Brain cortex Planning, multitasking, navigation, memory problems, anxiety, agitation, and delusions
  • Brain stem Constipation, depression, sleep problems, fluctuations in blood pressure, and body temperature
  • Substantia nigra Movement symptoms, including resting tremors, shuffling walk, and slowness

Dementia with Lewy bodies can also happen in people without PD who have cognitive issues but no dysfunction in body movement. Although it often goes underdiagnosed, scientists estimate that about 1.4 million Americans have some form of LBD. Similar to Parkinsons, people with LBD have low levels of the neurotransmitters dopamine and acetylcholine. Risk factors for LBD include being male, over age 60, and having a family history of PD or LBD.

Why Does Dementia Cause Delusions Hallucinations And Paranoia

When healthy nerve cells in the brain begin to degrade and cease to connect with other cells in the brain, the symptoms of dementia that often include delusions, paranoia or hallucinations will begin to appear. In general, people will lose a certain percentage of neurons as they grow older, but seniors who suffer from dementia will suffer a higher percentage of cell loss than normal. Dementia is usually found in seniors, and those aged 85 and up are more likely to have at least some form of the condition. That being said, there are many seniors who live well past the age of 90 and will never experience any form of dementia. A specific form of dementia, frontotemporal disorders, is typically experienced by middle-aged people as opposed to seniors.

Dementia is used as a catch-all term for a series of conditions and diseases that present with an overall decline in certain functions. A decline of language, memory, basic thinking skills, and the ability to solve problems are the main symptoms. Dementia sufferers also often experience what is called Sundowners Syndrome. Memory loss is one of the most notable side effects of dementia, and Alzheimers disease is the leading cause of dementia in senior citizens.

Lewy Body Dementia Hallucinations: What To Know

Dr. Allen Power: Delusions and Hallucinations in Dementia

When most people hear the word dementia, they think of Alzheimers disease. Although Alzheimers is one of the most common types of dementia, it is not the only type. The second most likely kind of dementia is caused by a buildup of proteins in the brain, known as Lewy bodies. When Lewy bodies accumulate, they can lead to symptoms of hallucinations and other cognitive and nervous system problems. People living with Parkinsons disease are more susceptible to Lewy body dementia compared to the general population. They may experience mild or severe cognitive symptoms that typically progress over time. Living with a rapid eye movement sleep behavior disorder is also a risk factor for acquiring LBD.

Here is what you should know about LBD if you or a loved one has PD.

What Are Hallucinations

A hallucination is an experience of something that is not really there. It can involve any or all of the senses.

Visual hallucinations are the most common type experienced by people with dementia. They can be simple or complex .

People with dementia are often thought to be hallucinating when in fact they are simply mistaken about what they have seen .

Stage : Mild Dementia

At this stage, individuals may start to become socially withdrawn and show changes in personality and mood. Denial of symptoms as a defense mechanism is commonly seen in stage 4. Behaviors to look for include:

  • Difficulty remembering things about one’s personal history
  • Disorientation
  • Difficulty recognizing faces and people

In stage 4 dementia, individuals have no trouble recognizing familiar faces or traveling to familiar locations. However, patients in this stage will often avoid challenging situations in order to hide symptoms or prevent stress or anxiety.
