Do You Hallucinate With Parkinson’s

Delusions From Parkinsons Disease

Hallucinations and Parkinson’s with Dr. Friedman

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.

Hallucinations And Delusions In Parkinsons Disease

It might be surprising to learn that 20 to 30 percent of people with Parkinsons disease will experience visual hallucinations. While typically not a symptom of PD itself, they can develop as a result to a change in PD medication or as a symptom of an unrelated infection or illness. It is important to know the signs of hallucinations and how to manage them.

Hallucinations and other more severe perceptual changes can be distressing to family often more so than to the person experiencing them. For the well-being of people with PD and caregivers, it is important to identify hallucinations as early as possible and take steps to reduce them.

The following article is based on the latest research and a Parkinsons Foundation Expert Briefings about hallucinations and delusions in Parkinsons hosted by Christopher G. Goetz, MD, Professor of Neurological Sciences, Professor of Pharmacology at Rush University Medical Center, a Parkinsons Foundation Center of Excellence.

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.

  • Behavior: Anxiety, agitation, reports of abnormal or unusual symptoms, extreme concern regarding symptoms, frequent visits with the clinician.
  • Do People Die From Parkinson’s


    PD does not directly kill patients people with PD die from other causes, not from PD itself. Two major causes of death for those with PD are falls and pneumonia.

    People with PD are at higher risk of falling, and serious falls that require surgery carry the risk of infection, adverse events with medication and anesthesia, heart failure, and blood clots from immobility.3

    Pneumonia is a common cause of death, and those with PD are at risk for aspiration pneumonia.3 People with PD often have problems with swallowing, so the risk of aspirating food or drink, or having food or drink going down the wrong pipe is higher. In PD, the person may not be able to cough up the food or drink they aspirated, and it can remain in the lungs, eventually causing an infection.3 Even with general pneumonia, when coughing is weakened, as in PD, the mucus and other material that needs to be coughed up isnt able to be expelled, and this makes effective treatment of pneumonia more difficult in those with PD.

    Can Hallucinations Be Treated

    The treatment for hallucinations consists primarily of removing any existing medical cause, especially reducing or stopping any triggering pharmacological cause for example by reducing a dose or discontinuing treatment with a certain drug. If the increase in motor symptoms then becomes troublesome, a return to the earlier anti-Parkinsons drug may be considered, but with the addition of an atypical neuroleptic drug.

    Most neuroleptics can worsen Parkinsons and are forbidden when treating people with the condition. Medications for dementia can also reduce the incidence of illusions and hallucinations when there is underlying cognitive impairment. Parkinsons treatments are developing fast and it is likely that we will see even more effective ways of avoiding and treating hallucinations in the coming years.

    The most important thing is to report hallucinations to your doctor or nurse, and to discuss if they should be treated in some way.

    Selfcare For The Person With Parkinsons

    • Join a Parkinsons support group if you dont already belong to one. Talk about your experiences, ask for help if you need it and share whats worked and not worked for you.
    • Offer to have coffee with someone you know has been newly diagnosed and offer them support and encouragement.
    • Make time to exercise and get out in nature every day.
    • Communicate frequently with your doctors and discuss the possibility of tweaking your medications if your symptoms become worse.
    • Rest when you need it.
    • Plan a day trip or a vacation and get away from your normal surroundings.
    • Take control where you can and keep authoring your own story.
    • Practice meditation or yoga or Tai Chi to relax and calm your mind.
    • Start a new project that youre excited to work on every day.
    • Communicate with your care partners and let them know how they can best help you.

    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|A term used to describe a group of brain disorders that cause a broad complex of symptoms such as disorientation, confusion, memory loss, impaired judgment and alterations in mood and personality.] 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.

    Minor Hallucinations Common Impactful In Parkinson Disease

    Hallucinations and Parkinson’s with Dr. Friedman

    More than 1 in 3 patients with Parkinson disease were found to experience minor hallucinations, which were linked with worse quality of life and poor sleep outcomes.

    Minor hallucinations were found to be the most common psychotic symptom in patients with Parkinson disease , in which those affected reported reduced health-related quality of life and greater sleep symptom burden. Findings were published in Behavioural Neurology.

    Although PD psychosis affects up to 75% of patients throughout the disease course, researchers highlight that prevalence of psychotic symptoms, including minor/major hallucinations and delusions, are typically understated and are not fully considered as key characteristics of the condition.

    In fact, findings of a recent study showed that just 11% of caregivers reported having been educated by a physician on PD psychosis, with more respondents learning from personal research.

    Minor hallucinations deserve widespread attention because it is the most frequent and earliest type of psychotic phenomenon in PD and occurs even before the onset of motor symptoms, said the researchers. Minor hallucinations might also be an early predictor of a severe psychotic and cognitive state.

    Participants answered a series of clinical assessment questionnaires, with results of the Movement Disorders Society Unified Parkinsons Disease Rating Scale Part I leveraged to classify patients into eight strata:

    Parkinson’s Hallucinations Paranoid Thoughts & Delusions

    A psychotic episode typically involves seeing people and objects that are not there , hearing noises that dont exist and delusions . Delusions typically take the form of paranoid thoughts, such as a patient believing a that family member or friend has poisoned their food or that their spouse is cheating on them.

    During the later stages of PD, these episodes may cause the patient to become more confused and affect their connection with reality. For example, a loved one with PD may no longer be able to distinguish personal experiences from the those of the outside world. Typically, psychosis does not develop until several years after ones initial diagnosis of Parkinsons, but keep in mind that there are other conditions that may mimic the symptoms of PD psychosis. Delirium and various forms of dementia can be confused with PD psychosis and vice versa.

    Psychotic symptoms can be extremely disturbing to the person experiencing them and can create a challenging situation for all who are involved in providing care.

    Medications Used For Treating Psychosis

    Antipsychotic agents are designed to balance abnormal chemical levels in the brain. Up until the 1990s, the use of antipsychotics in PD was controversial because the drugs used until that time work by reducing excess dopamine. This alleviated psychosis but caused dramatic worsening of PD motor symptoms.

    Fortunately, medications that are better tolerated by people with PD are now available. Today, there are three antipsychotic medications considered relatively safe for people with PD: quetiapine , clozapine and the newest agent, pimavanserin . They cause limited worsening of PD while treating hallucinations and delusions.

    If there is no underlying medical condition, changes to lifestyle may lessen the frequency of hallucinations. Getting enough sleep and avoiding drugs and alcohol can reduce their frequency. If hypnagogic hallucinations cause disrupted sleep or anxiety, a doctor might prescribe medication.

    How Can You Tell If Someone Is Hallucinating

    Sometimes the person may appear to be hallucinating, but there is another cause . The following tips can help to identify hallucinations:

    • Hallucinations differ from misperceptions or misidentifications. Listen to what the person is describing, and check if anything could be causing what they are experiencing. For example, if they describe a swarm of insects, and there is a busy pattern on a carpet, it may be a misperception. By changing or covering the carpet, the misperception may stop.
    • If the person seems to be having auditory hallucinations , arrange to have their hearing checked. If the person wears a hearing aid, check that it is working properly at the right setting, and encourage them to wear it. The person may be having problems with their hearing, rather than hallucinating.
    • If the person seems to be having gustatory hallucinations , make sure they are getting regular dental check-ups to rule out other causes such as tooth decay or denture cream. For more information see Dental care and oral health.

    All About Hallucinations In Seniors With Dementia

    By Ben Isaac 9 am on December 31, 2020

    Many people think dementia mostly just causes memory loss, but this complex neurological condition can also cause unusual symptoms such as hallucinations. These hallucinations can include seeing, smelling, or hearing things that arent there, and theyre most common in seniors with dementia due to Alzheimers, Parkinsons, or Lewy bodies. Not all seniors experience hallucinations, but its important for dementia caregivers to know the signs and how to manage the symptoms. If your senior loved one experiences dementia-related hallucinations, there are a few things you can do to address the situation and maintain his or her wellbeing.

    Treatment Options For Pd Psychosis

    Joseph H. Friedman, M.D.: Hallucinations and Parkinson’s

    Treating psychosis is truly a challenge. Unfortunately, only 10 to 20 percent of people with PD psychosis actually inform their doctor of their symptoms. Dr. Dewey speculates that stigma and fear of embarrassment prevent many patients from seeking help.

    When new symptoms of any kind arise, it is crucial to make a doctors appointment to discuss the issue. A physician will first try to determine whether there is an underlying illness that could be causing psychotic behaviors. Treating the underlying cause is one of the simplest ways of minimizing these episodes.

    When there is no other identifiable source, doctors often turn their attention to the medications that the patient is taking. Gradually decreasing the dosage of dopamine-enhancing medication may reduce psychotic symptoms, but the obvious trade-off is that the persons motor function is likely to deteriorate more rapidly. Balancing risks and benefits is a delicate and complicated process that often involves a three-step approach, including assessment and planning, adjusting or reducing any medications, and initiating antipsychotic therapy.

    Medical research produces discoveries continually, so keeping an ongoing dialogue open with your loved ones doctor should be a priority. Finding the best balance of treatment is crucial for optimum care and quality of life.

    Phenomenology Of The Hallucinations

    Minor hallucinations/illusions

    We grouped together in this category three types of phenomena. The most frequent type was presence hallucinations . The patient had the vivid sensation of the presence of somebody either somewhere in the room or, less often, behind him or her. In all cases, the presence was that of a person, and in one case it was also occasionally the presence of an animal . In seven cases, the presence was that of a relative . In all the other cases the presence was unidentified. The presence hallucinations were commonly as vivid as a hallucinated scene and were described as a `perception’. For instance, one patient said: `the image is behind me’, a second said: `I see someone arriving I turn back but nobody is there’, a third said: `I take a look I don’t see anything, but it is engraved in my mind’, and another said: `I have the impression that my mother is always there, that she is about to come into sight’. The passage hallucinations consisted of brief visions of a person or an animal passing sideways. If an animal was seen, the species was almost invariably specified , and in two instances it was a dog previously owned by the patient. Illusions occurred in nine patients . In five cases the illusion consisted of the transformation of an object into an animal .

    What Is Parkinson’s Psychosis

    Parkinsons disease psychosis is a common and very disabling non-motor feature of this disease. It is considered a neuropsychiatric condition, since it deals with mental health symptoms caused by a disease of the nervous system . “Parkinson’s patients have a substantial risk of eventually developing this problem, says Richard B. Dewey Jr., MD, professor of Neurology and Neurotherapeutics and Director of the Clinical Center for Movement Disorders at the University of Texas Southwestern Medical Center.

    Indeed, 50 percent of people with PD will experience an episode of psychosis at least once, usually in the form of a visual hallucination. Caregivers and patients alike often wonder what happens in the body to cause this debilitating symptom and how it can be prevented or minimized.

    Medications To Help Treat Parkinsons Disease Psychosis

    Your doctor might consider prescribing an antipsychotic drug if reducing your PD medication doesnt help manage this side effect.

    Antipsychotic drugs should be used with extreme caution in people with PD. They may cause serious side effects and can even make hallucinations and delusions worse.

    Common antipsychotic drugs like olanzapine might improve hallucinations, but they often result in worsening PD motor symptoms.

    Clozapine and quetiapine are two other antipsychotic drugs that doctors often prescribe at low doses to treat PD psychosis. However, there are concerns about their safety and effectiveness.

    In 2016, the approved the first medication specifically for use in PD psychosis: pimavanserin .

    In clinical studies , pimavanserin was shown to decrease the frequency and severity of hallucinations and delusions without worsening the primary motor symptoms of PD.

    The medication shouldnt be used in people with dementia-related psychosis due to an increased risk of death.

    Psychosis symptoms caused by delirium may improve once the underlying condition is treated.

    There are several reasons someone with PD might experience delusions or hallucinations.
