Can Parkinson’s Disease Cause Hallucinations

Selfcare For The Person With Parkinsons

Understanding Hallucinations in Parkinson’s Disease
  • 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 or 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.

The Cause Of Parkinsons Delusions And Hallucinations

Some risk factors associated with the development of psychosis in Parkinsons disease include:

  • Age: Parkinsons disease usually occurs in people over age 60.
  • Duration and severity of Parkinsons disease: Psychosis is more common in advanced or late-stage Parkinsons disease.
  • Later onset: Occurring later in life
  • Hyposmia: A decreased sense of smell
  • Cognitive impairment: Problems with thinking, including trouble remembering, difficulty learning new things, difficulty concentrating, problems making decisions that affect everyday life
  • Depression: People who have both depression and Parkinsons disease are at a greater risk of developing psychosis.
  • Diurnal somnolence: Daytime sleepiness
  • REM sleep behavior disorder: A sleep disorder in which you physically act out dreams; involves making vocal sounds and sudden, often extreme, arm and leg movements during REM sleep
  • Visual disorders: Impaired vision
  • Severe axial impairment: Speech, swallowing, balance, freezing of gait
  • Autonomic dysfunction: Impairment of the autonomic nervous system , which controls involuntary or unconscious actions such as heart rate, breathing, body temperature, blood pressure, digestion, and sexual function
  • High medical comorbidity: The existence of more than one condition or illness in the same person at the same time; with Parkinsons disease, may include conditions such as dementia, depression, and sleep disorders

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.;

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 .

Types Of Hallucinations In People With Parkinsons Disease

10 early warning signs of Parkinson

Hallucinations involve the five senses: sight, smell, touch, hearing, and taste.

People with hallucinations have sensory experiences that feel real to them, but are not actually happening and are not apparent to anyone else.

Types of hallucinations include:

  • Auditory: Hearing things
  • Gustatory: Tasting things

For people who experience Parkinsons-related hallucinations, the hallucinations are usually visual. They are typically non-threatening, but less commonly they can be of a threatening nature.

Often people with Parkinsons disease psychosis see small people or animals, or;loved ones who have already died. They are not interacting with them, just being observed.

Auditory hallucinations are more common in people with schizophrenia, but can happen with Parkinsons disease. With Parkinsons disease, auditory hallucinations are usually accompanied by visual hallucinations.

More specific types of hallucinations experienced by people with Parkinsons disease include:

Practical Tips For Caregivers Of People With Parkinson’s Psychosis

This 2-page tip sheet has bullet point suggestions for what to do if the person you care for experiences hallucination, delusions or confusion, or becomes agitated or aggressive. ;In addition, there are tips for how to best be prepared for a doctors appointment when you bring this behavior to the attention of your medical team.

Common Causes Of Hallucinations

Hallucinations most often result from:

  • Schizophrenia. More than 70% of people with this illness get visual hallucinations, and 60%-90% hear voices. But some may also smell and taste things that aren’t there.
  • Parkinson’s disease. Up to half of people who have this condition sometimes see things that aren’t there.
  • Alzheimer’s disease. and other forms of dementia, especially Lewy body dementia. They cause changes in the brain that can bring on hallucinations. It may be more likely to happen when your disease is advanced.
  • Migraines. About a third of people with this kind of headache also have an “aura,” a type of visual hallucination. It can look like a multicolored crescent of light.
  • Brain tumor. Depending on where it is, it can cause different types of hallucinations. If it’s in an area that has to do with vision, you may see things that aren’t real. You might also see spots or shapes of light. Tumors in some parts of the brain can cause hallucinations of smell and taste.
  • Charles Bonnet syndrome. This condition causes people with vision problems like macular degeneration, glaucoma, or cataracts to see things. At first, you may not realize it’s a hallucination, but eventually, you figure out that what you’re seeing isn’t real.
  • Epilepsy. The seizures that go along with this disorder can make you more likely to have hallucinations. The type you get depends on which part of your brain the seizure affects.

What Are The Symptoms Of Psychosis

Parkinson’s Minute: Psychosis

Two of the most prominent symptoms are hallucinations and delusions.7 Hallucinations involve seeing, hearing, experiencing or sensing things that are not really there. Delusions are false beliefs that are not based in reality. In describing symptoms of Parkinsons disease psychosis, patients may use such common terms as: seeing things, paranoia, flashbacks, nightmares, false beliefs, or not being in touch with reality.8

How To Avoid Dip

The incidence rate of DIP has proved difficult to assess, due to the prevalence of misdiagnosis as PD. Older people and women are at higher risk of DIP, and genetic factors may also play a role.2

The only way to develop DIP is by taking a prescription drug that impacts the brains dopamine system. If you dont take those drugs, you cannot develop it.

Unfortunately, in some cases, DIP is misdiagnosed as PD. Researchers discovered that 6.8% of patients diagnosed with PD were later reclassified as having DIP.3 This mistake is particularly harmful since doctors may prescribe drugs to manage PD symptoms instead of stopping the drug thats causing DIP.

Discontinuing the responsible drug most often ends DIP. However, in some cases, the symptoms persist. In others, the parkinsonism continues to worsen along a track consistent with PD. Researchers have postulated that in these cases the drugs unmasked PD, which may have otherwise gone unexpressed.

Synopsis

If you dont take a prescription drug that causes DIP, then you cannot develop it. People experiencing DIP can usually end it by discontinuing the medication that caused it, but for some people, the symptoms persist or worsen.

Parkinsons disease affects approximately 1 million people in the United States, and more than half of patients with PD will develop Parkinsons disease psychosis at some point in the course of their disease.1,2 The presentation of this condition is distinct from that of other psychotic conditions.3 It may include a range of symptoms, predominantly visual hallucinations, as well as auditory hallucinations and delusions.4-6 Less common symptoms may include olfactory and tactile hallucinations.4 These symptoms tend to increase in severity over time.7

Establishing a Diagnosis of PDP

PDP: Contributory Factors

Factors contributing to PDP may be classified as intrinsic or extrinsic. Extrinsic factors may include medications and environmental factors, whereas intrinsic factors include comorbid conditions, disease progression, and neurochemical abnormalities associated with neurodegeneration.8,11-13 In characterizing the extrinsic and intrinsic factors associated with PDP, it is important to note that NUPLAZID is approved only for treatment of the hallucinations and delusions associated with PDP.14

How Hallucinations May Affect You

Psychosis in parkinsons disease

Hallucinations can be mild or they can be quite frightening, especially when you dont realise that the things you see or hear arent real. Some people will be aware that they are hallucinating, and some wont be. Some people might prefer to tolerate a relatively harmless hallucination, rather than reduce their medication and possibly have an increase in their physical symptoms.

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.

Other Symptoms Of Parkinsons Disease

There are numerous Parkinsons disease symptoms, some related to movement and some unrelated. In addition to hallucinations and delusions, people may experience other non-motor symptoms, such as poor sleep and vision problems, which often contribute to the development of hallucinations.

Other non-motor Parkinsons disease symptoms include:

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.

Why Isnt There A Greater Awareness Of Parkinsons Disease Psychosis

Parkinsons Disease Psychosis: Hallucinations, Delusions & Paranoia

Its not uncommon for people with Parkinsons disease psychosis to remain silent about their experiences.2,4,9 In fact, only 10% to 20% actually report their symptoms to their physicians.4-9 Work continues to be done to raise awareness of this condition.

It is estimated that about 50% of people with Parkinsons will, at some point, experience hallucinations. They can affect younger people but are more often associated with those who are older and have had Parkinsons for some time.

Hallucinations experienced early in Parkinsons may also be a symptom of the condition dementia with Lewy bodies; so it is important to let your doctor know if hallucinations begin at an early stage.

Parkinsons itself can be a cause of hallucinations and delusions, but very often they are a side effect of certain medications used to treat the condition. Not everyone who takes Parkinsons medications will experience hallucinations and delusions though. This varies from person to person and is often related to the particular type of medication and dosage.

Other factors may also be involved such as underlying illness, memory problems, sleep difficulties and poor eyesight.

How To Talk To Someone With Hallucinations Or Delusions

  • It is usually not helpful to argue with someone who is experiencing a hallucination or delusion. 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.
