How Common Is Parkinsons Disease Psychosis
Between 20-40% of people with Parkinsons report the experience of hallucinations or delusions. When followed as the disease progresses over the years, this number increases. The increase does not mean that the hallucinations are persistent across the majority of patients. However, it is important to note that these statistics sometimes include delirium, in which the symptoms are temporary due to medication that needs to be adjusted or infection that needs to be treated, and isolated minor symptoms or minor hallucinations, including illusions, where instead of seeing things that are not there , people misinterpret things that are really there. These are the most common types of psychosis in people with PD, with different studies placing the occurrence between 25-70% of people with Parkinsons. Typically, if the person with PD only has these minor hallucinations, their doctor will not prescribe an antipsychotic medication, though more significant psychosis that requires medication may develop over time. In one study, 10% of those with minor hallucinations had their symptoms resolved within a few years, while 52% saw their symptoms remain the same and 38% saw their psychosis symptoms get worse.
We recommend that people with Parkinsons not use a single percentage to represent the prevalence of hallucinations and PDP. Parkinsons is a complex disease and as it progresses the percentages and risk of symptoms will change.
Demystifying Hallucinations Night Terrors And Dementia In Parkinsons
This two-hour webinar includes extensive discussion about hallucinations, delusions, illusions and other examples of Parkinsons psychosis in Parkinson’s. Presenters: Rohit Dhall, MD, MSPH and Vergilio Gerald H. Evidente, Director, Movement Disorders Center of Arizona in Scottsdale. Pay particular attention to Dr. Rohit Dhalls description of the causes of PD psychosis as well as treatment options and what to discuss with your movement disorder specialist. Dr. Evidente gives a clear description on differences in PD dementia, Alzheimer’s and other dementias.
I Had A Hallucination: What Next
Research has shown that for many people with PD who have them, hallucinations begin after a change in medication, more specifically, an increase in levodopa . Additional factors make a person more likely to experience hallucinations when medications are changed, such as other cognitive problems or memory issues, depression and sleep problems. Dementia also increases the risk of hallucinations and delusions when PD medications are changed. Dementia means cognitive changes whether in memory, judgment or attention that interfere with daily life.
One thing that does not affect the risk of hallucinations is your regular dose of levodopa. Rather, studies show that it is a change in dose an increase in a dose that has been stable that sets off hallucinations.
Tip: Experiencing a hallucination does not mean you are going crazy. Many people recognize that their hallucinations are not real. Do not react to these visions or sounds or engage them dismiss them. Bring up the topic with your doctor immediately.
People with Parkinsons often ask, Is my hallucination a one-time event? A study sought to answer this by tracking 89 people with PD for 10 years. At the beginning, about a third experienced hallucinations. Over time, more participants experienced them. The study found that most people with PD who hallucinate will most likely continue to do so, and over time hallucinations can worsen. Also, after 10 years, most of the participants experienced hallucinations.

What Is Parkinsons Disease Psychosis
As Parkinsons Disease progresses, up to 40 percent of the approximately one million Americans living with the illness will develop psychotic symptoms, primarily hallucinations, but also delusions. These symptoms can be an indication of Parkinsons disease psychosis , but unfortunately, many patients are not diagnosed. Sometimes, the symptoms of PDP are misdiagnosed. Other times, patients and their families may not be comfortable sharing the symptoms with their physician team.
What Are Parkinsons Hallucinations
Symptoms of psychosis occur in up to 50% of people with Parkinsons disease.
Parkinsons disease psychosis is considered a neuropsychiatric condition. This means it involves neurology and psychiatry . While the psychosis involves mental health symptoms, they are caused by Parkinsons disease, which is a disease of the nervous system.
Psychosis in Parkinsons disease comes in two forms:
- Hallucinations: Sensory experiences that are not really happening
- Delusions: False beliefs not based on reality
These symptoms can be debilitating and scary for the people experiencing them. They can interfere with a persons ability to care for themselves and to relate to other people.
Psychotic symptoms in Parkinsons disease are associated with increased caregiver distress, risk of hospitalization and nursing home placement, and healthcare costs.
A study suggests the presence of hallucinations and delusions in people with Parkinsons disease is a predictor of mortality .

What Are Parkinsons Disease
Delusions are false beliefs that are not based on reality. These beliefs are fixed. People experiencing them are unlikely to change or abandon these beliefs, even when presented with evidence that they are false.
Delusions experienced by people with Parkinsons disease are usually of a common theme. These may include:
- Spousal infidelity
- Thinking that people are stealing their belongings
- Thinking people are trying to harm them
- Thinking people may put poison in their food
- Thinking people are switching out or substituting their medications
- Other beliefs based on paranoia
Delusions From Parkinsons Disease
Delusions affect only about 8 percent of people living with PD. Delusions can be more complex than hallucinations. They may be more difficult to treat.
Delusions often start as confusion that develops into clear ideas that arent based on reality. Examples of the types of delusions people with PD experience include:
- Jealousy or possessiveness. The person believes someone in their life is being unfaithful or disloyal.
- Persecutory. They believe that someone is out to get them or harm them in some way.
- Somatic. They believe they have an injury or other medical problem.
- Guilt. The person with PD has feelings of guilt not based in real behaviors or actions.
- Mixed delusions. They experience multiple types of delusions.
Paranoia, jealousy, and persecution are the most commonly reported delusions. They can pose a safety risk to caregivers and to the person with PD themselves.
PD isnt fatal, though complications from the disease can contribute to a shorter expected life span.
Dementia and other psychosis symptoms like hallucinations and delusions do contribute to increased hospitalizations and increased rates of death .
One study from 2010 found that people with PD who experienced delusions, hallucinations, or other psychosis symptoms were about 50 percent more likely to die early than those without these symptoms.
But early prevention of the development of psychosis symptoms may help increase life expectancy in people with PD.

Who Is At Risk For Psychosis
Theres no predicting with certainty which patients with Parkinsons disease will go on to develop symptoms like hallucinations or delusions. A number of risk factors both internal and external- are associated with the condition.Some of these risk factors include: age, duration and severity of Parkinsons disease and the taking of dopamine therapy.3-6
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.

Treatments And Outcomes Of Dip
DIP is generally treated by cessation of the offending drugs. Patients who cannot stop taking antipsychotic drugs because of their psychiatric diseases, such as those with schizophrenia or major depressive disorders, may be switched to atypical antipsychotics that have a lower risk of EPS. People who are prescribed dopamine antagonists due to simple GI disturbance, headache, dizziness, or insomnia should stop taking the offending drugs as soon as possible. Anticholinergics including trihexyphenidyl, benztropine, amantadine, and levodopa have been empirically tested for their ability to relieve symptoms of DIP, but this has produced no clear evidence of their effects in DIP patients.,,,,
Changes In Nerve Network Of Brain May Cause Presence Hallucinations
My first experience with hallucinations was terrifying not for me at first, but for my husband, who watched it happen.
We were on a cruise, and my anti-nausea medications interacted with my Parkinsons medications, resulting in two episodes. The first occurred in the middle of the ship around tons of people. I was sitting in the theater waiting for a show to start when my husband walked up and asked me to scoot over a seat. I told him that my mom was sitting there and had just walked over to the bar to get a drink. He was very confused because my mom was not with us on the trip.
Later that night, I had another episode. While my husband was sleeping, I tore apart our room, thinking I was packing. He woke up and asked, What are you doing? I told him that we had to go pick up our dog from doggy day care. After a few moments of total confusion, he reminded me that it was the middle of the night and we were in the middle of the ocean. He also told me that our dog was safe at my parents house and not at day care.
To learn more about Parkinsons hallucinations, I spoke with Andrea Frost, whose brother has the disease. She shared the following story with me:
I also talked with Alan Tobey, a 77-year-old living with Parkinsons, who said:

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.

Visual Hallucinations According To The Duration Of Parkinson’s Disease
The prevalence of hallucinations of all types and of visual hallucinations in the 3 months preceding inclusion in the study increased with the duration of Parkinson’s disease . We compared the characteristics of the patients with and without hallucinations among those with a short history of Parkinson’s disease and those with a long history . The results are shown in Table 7. Visual hallucinations had been present for a mean of 0.8 years in the patients with short-duration Parkinson’s disease and for 2.4 years in the patients with long-duration Parkinson’s disease . However, eight patients with long-duration Parkinson’s disease and one patient with short-duration Parkinson’s disease could not remember the year of onset of visual hallucinations. In both groups, patients with formed visual hallucinations were older and were more likely to be demented, according to DSM criteria, than non-hallucinators. The MMP score was lower in patients with visual hallucinations, although the difference reached significance only in patients with long-duration Parkinson’s disease. Patients with visual hallucinations had a more severely affected motor state than non-hallucinators in the long-duration group only.
How Can I Get Help
First and most importantly, if you find yourself experiencing symptoms such as hallucinations or delusions, speak out. It is essential to talk about your full range of Parkinsons disease symptoms with your treatment team. A dialogue among patients, care partners, and physicians is a critical component of the effective management of your condition.
