Hallucinations And Delusions In Parkinsons Disease
This blog post is based on the latest research and a Parkinsons Foundation Expert Briefing about hallucinations and delusions in Parkinsons. After an explanation of what hallucinations and delusions are, there are tips for what to do, how to minimize these behaviors through lifestyle changes, and medication treatment options.
Etiology Of Psychotic Symptoms
PD is characterized by the loss of dopaminergic neurons with cell bodies residing in the substantia nigra pars compacta with resultant decreased dopamine release in the basal ganglia. The etiology of psychosis is less understood and may involve dysfunctional dopaminergic and serotonergic, and possibly cholinergic, pathways. Indeed, drugs that block dopaminergic receptors can cause extrapyramidal symptoms.
Risk factors for PDP include: exposure to dopaminergic medications, advancing age, increasing impairment in executive function, dementia, increasing severity and duration of PD, comorbid psychiatric symptoms such as depression and anxiety, daytime fatigue, sleep disorders, visual impairment, and polypharmacy . The presence of psychosis in patients with PD is a strong predictor of institutionalization. A study comparing PD patients still living at home with those in nursing care facilities found a 16-fold higher likelihood of hallucinations in the institutionalized group . Another review of a population of PD patients with psychosis found that after 2 years, hallucinations were linked to dementia , nursing home placement or death .

Pathophysiology Of Pd Psychosis
The precise pathophysiology of visual hallucinations in PD remains unclear however, neuropathological and structural imaging studies have provided some insight regarding the type and distribution of pathologic change associated with these phenomena. Neuronal loss in multiple brain regions, with associated LBs containing alpha-synuclein, is the principle pathological finding in Parkinsons disease . However, characteristic Alzheimers disease pathology can be found in the brains of patients with PD and is associated with earlier onset of dementia . Cognitive impairment is a risk factor for visual hallucinations, and concomitant AD pathology has been linked with the phenomena .
Dopamine cell loss in the substantia nigra is a required feature for the pathological confirmation of PD, but this is not the earliest affected area . According to Braaks hypothesis, LBD pathology begins in the olfactory regions and lower brain stem , progresses to the midbrain substantia nigra , and then to the basal forebrain, hypothalamus, thalamus, and hippocampus before spreading to higher-order cortical association areas . The evolution of visual hallucinations in PD has been conceptualized to mirror this spreading pathology with minor experiences indicating brainstem pathology, formed visual hallucinations with insight indicating basal forebrain involvement, and multimodality hallucinations with associated loss of insight and delusions indicating widespread cortical LBD pathology .
What Future Medications May Be Available For Parkinsons
There are numerous studies investigating new treatments for Parkinsons disease.
There has been new information about the role of autoimmunity and T-cells in the development of Parkinsons disease, possibly opening the door to a role for biologics.
Stem cells are also being investigated as a treatment option for Parkinsons disease.

New Drug Shows Promise In Treating Parkinson’s Disease Psychosis
Off-label drugs have been used to manage psychotic-related symptoms in Parkinson’s disease patients, but they worsen motor symptoms by reducing dopamine levels. Nuplazid is the only FDA-approved drug that treats Parkinson’s disease psychosis without impairing motor function.
Parkinson’s disease is a progressive neurodegenerative condition marked by bradykinesia, rigidity, tremor, and postural instability. While therapeutic advances have been made to improve motor-related symptoms, many older adults affected by this disease also develop Parkinson’s disease psychosis . Psychotic symptoms such as hallucinations and delusions develop in more than 50% of PD patients and can lead to severe impairments in cognitive, behavioral, and emotional function.1
PDP Drives Nursing Home Placement According to the Parkinson’s Disease Foundation, 1 million people have been diagnosed with PD in the United States, and between 7 million and 10 million people worldwide have the condition. Hallucinations and delusions drive the nursing home placement and hospitalization of patients diagnosed with PDP, says Jason Kellogg, MD, chief of staff at Newport Bay Hospital in Newport Beach, California.
He adds that the delusions and hallucinations observed in PDP tend to be more dramatic in nature. For instance, these patients are usually high-functioning, well-dressed men and women. But their hallucinations are quite striking because they have delusions of persecution and visual hallucinations.

What Should I Do When My Loved One Is Experiencing A Hallucination
Most importantly, dont try to convince your loved one that what theyre experiencing isnt real. Theyll feel like youre putting down an experience that seems authentic to them.
Once a person has lost insight, itll be very difficult to convince them that what theyre experiencing isnt happening. Trying to argue with them may agitate and even enrage the person. Making them anxious could cause their hallucinations to get worse.
Instead, talk to the person gently and reassuringly. You might say something like, I understand that you see a dog in the corner of the room. Everything is going to be OK. Youre safe. You might even say that the dog must have left already.
Remember that the person cant control what theyre experiencing. Try to be as sympathetic as you can when you talk to them.
One approach that can help is to turn on all the lights in the room. Hallucinations are more likely to happen in dimly lit areas, and this can be caused by disease-related changes that affect the eyes.
Then, have the person really focus on what theyre seeing. That may reset their brain and help them see whats actually in front of them.
If the person doesnt have insight, try a distraction. Move them to a different room. Turn on the TV or play a game they like.
Try to keep your loved one as calm as possible. If they become very agitated or violent, call their doctor or 911.
How Delusions May Affect You
When delusions are mild, the person with Parkinsons may know what is happening and can be helped to overcome their false beliefs. A GP or specialist may just monitor the situation.
However, when delusions make people suspicious and distrusting, they can cause problems in relationships, medications and treatments.
With a serious delusion, there is a chance the person could accuse your partner or a family member of something they havent done. They may no longer be able to tell whether things are real or not, which can make them feel very anxious or irritable.
Some people with Parkinsons experience a mixture of hallucinations and delusions. This could lead them to feeling confused and can have an impact on day-to-day life.

What Causes Parkinsons Disease Psychosis
Parkinsons is a brain disorder associated with a loss of dopamine-producing nerve cells deep inside the brain. Dopamine is a neurotransmitter that helps regulate the bodys movement, and it also allows us to think clearly and regulate our emotions. When you try to replace the dopamine thats been lost in a person with Parkinsons, it can cause the system to get out of whack which can impact thinking, how visual things are processed and more. Parkinsons disease psychosis is therefore typically a side effect of the disease itself or the medications used to manage it.
As a result, its an ongoing balancing act for Parkinsons doctors to prescribe enough dopamine to control a person with Parkinsons motor symptoms, but not so much that the person experiences hallucinations and/or delusions.
Attitudes Of Care Partners Toward Medications For Parkinsons Disease Psychosis
Category:Parkinsons Disease: Psychiatric Manifestations
Objective: To explore attitudes regarding use of medications among care partners of individuals with Parkinsons disease psychosis.
Background: Parkinsons disease psychosis is a highly morbid manifestation of PD and negatively impacts the quality of life of both patients and their care partners . Effective therapies for PD psychosis exist, but some carry significant risk. Understanding CP attitudes regarding medications for PD psychosis could help inform healthcare provider discussions and promote shared decision-making regarding their use.
Method: This was a mixed-methods study. Prompted online journaling activities and structured telephone interviews were conducted with CPs of patients with PD psychosis, identified via Fox Trial Finder. Using common themes from journaling and telephone interviews, a survey was then developed and administered to caregivers of PD patients participating in the online study Fox Insight. The survey included the Neuropsychiatric Inventory , Caregiver Burden Inventory , and a multiple-choice questionnaire regarding attitudes on medications.

Risk Factors And Conceptual Models For Visual Hallucinations In Pd
Several disease-related and other factors have been linked to visual hallucinations in PD. The presence of visual hallucinations is associated with the duration of PD , older age, disease severity, and the presence of motor fluctuations . Other established risk factors include female sex , visual impairment , cognitive impairment , REM sleep behavior disorder , autonomic dysfunction , depression , apathy , and anxiety . A bidirectional association between visual hallucinations and cognitive impairment has been observed in PD, with the presence of minor visual hallucinations often preceding any significant cognitive decline and visual hallucinations representing a risk factor for later development of PD dementia .
Studies of the etiological basis of visual hallucinations in PD psychosis have focused on both the role of individual risk factors and the interrelationships between multiple factors. Explanatory models have emphasized dysfunction of components of attentional and perceptual processing or dream imagery intrusion with dopaminergic and other medications as likely playing a modulating role .
Dysfunctional attentional network interactions have also been demonstrated in DLB , which may be associated with the generation of visual hallucinations . In addition, thalamo-cortical dysfunction, with decoupling between thalamic nuclei and the DMN, has been proposed to underly psychosis in DLB and PD .

Do Hallucinations Go Away
Some visual hallucinations are so mild they might not even register on a conscious level, Dr. Ramdhani says. For instance, you may see a shadow thats not there, or glimpse something in your peripheral vision that clears when you turn your head. For some people, those may go away on their own, especially with a change in medication. In more advanced stages, though, these hallucinations may occur along with delusions, which means a false belieflike thinking your spouse isnt your real partner. Dr. Ramdhani says this can happen due to cognitive impairment, such as dementia.
Memory Problems And Dementia
Research shows that hallucinations and delusions often happen when someone with Parkinsons also has problems with memory, thinking problems or dementia.
If you experience hallucinations at an early stage of Parkinsons, it could be a sign of another medical condition, such as dementia with Lewy bodies.

Hallucinations And Delusions In Pd
Hallucinations and delusions are collectively referred to as psychosis.
Visual hallucinations are the most common type of hallucination. In a visual hallucination, someone sees things that are not actually there. There can also be auditory and olfactory hallucinations. Often hallucinations are not alarming to the person experiencing them.
Delusions are when there is an alternative view of reality: an entire irrational story is created. Paranoia is a common type of delusion. Capgras delusions are a specific type of delusion where the person believes that a spouse, adult child, or other family member has been replaced by an imposter.
Dopamine Agonist Withdrawal Syndrome
If you suddenly stop taking dopamine agonists, this can lead to dopamine agonist withdrawal syndrome, which can cause symptoms such as depression, anxiety or pain.
Any withdrawal from Parkinsons drugs needs to be done in a tapered way, under the supervision of a health professional.
Speak to your specialist for advice.

Hallucinations And Rem Sleep Disorders In Parkinsons Disease
At timestamp 1:58 in this recording of Thrive: HAPS 2020 Caregiver Conference, you will find a one hour talk by neurologist Joohi Jimenez-Shahed, MD. In it she delves into what REM sleep behavior disorder is and is not, and the distinctions between hallucinations, delusions, and delirium. Managment options for RBD and hallucinations are included.
How Commonly Do Parkinsons Disease Patients Develop Psychosis
Psychosis in Parkinsons disease generally comes in two forms: hallucinations or delusions . When hallucinations occur, they are mostly visual . Sometimes, they can be threatening, but this is less common. Auditory hallucinations are rare in Parkinsons disease and if they do occur, they are usually accompanied by visual hallucinations.
Delusions are usually of a common theme, typically of spousal infidelity. Other themes are often paranoid in nature Because they are paranoid in nature, they can be more threatening and more immediate action is often necessary, compared to visual hallucinations . It is not uncommon that patients actually call 9-1-1 or the police to report a burglary or a plot to hurt them.
Unfortunately, psychosis occurs in up to 40% of Parkinsons disease patients . In the early stage of Parkinsons disease psychosis, the patient often still has a clear understanding and retains their insight, but this tends to worsen over time and insight may eventually be lost. At later stages, patients may be confused and have impaired reality testing that is, they are unable to distinguish personal, subjective experiences from the reality of the external world. Psychosis in Parkinsons disease patients frequently occurs initially in the evening, then later on spills into the rest of the day.

How To Talk To Someone With Hallucinations Or Delusions
- It is usually not helpful to argue. Avoid trying to reason. Keep calm and be reassuring.
- You can say you do not see what your loved one is seeing, but some people find it more calming to acknowledge what the person is seeing to reduce stress. For example, if the person sees a cat in the room, it may be best to say, “I will take the cat out” rather than argue that there is no cat.

First Drug Approved For This Indication
WASHINGTON The FDA has approved pimavanserin for the treatment of hallucinations and delusions associated with psychosis experienced by some people with Parkinsons disease, the agency announced Friday.
Hallucinations or delusions can occur in as many as 50% of patients with Parkinsons disease at some time during the course of their illness, the FDA said in a press release.
Hallucinations and delusions can be profoundly disturbing and disabling,Mitchell Mathis, MD, director of the Division of Psychiatry Products in the FDAs Center for Drug Evaluation and Research, said in the release. Nuplazid represents an important treatment for people with Parkinsons disease who experience these symptoms. It is the first drug approved for this indication, the FDA noted.
In a 6-week clinical trial of 199 participants, Nuplazid was found to be superior to placebo in decreasing the frequency and/or severity of hallucinations and delusions without worsening Parkinsons diseases primary motor symptoms.
The drug has a Boxed Warning advising of an increased mortality risk associated with the use of these drugs to treat older people with dementia-related psychosis, which would be an off-label use.
In clinical trials, the most common side effects reported by participants taking Nuplazid were swelling usually of the ankles, legs, and feet due to peripheral edema nausea and confused state.
