What Causes Hallucinations With Parkinson’s Disease

I Had A Hallucination: What Next

Understanding Hallucinations in Parkinson’s Disease

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.

What To Do About Parkinsons Hallucinations

Hallucinations or other signs of Parkinsons psychosis should be discussed with a doctor. Depending on the cause and severity of hallucinations, the person may or may not need treatment. If an infection is the cause, it should be treated accordingly. A doctor may want to change or reduce the dosage of any medications that could cause hallucinations to stop Parkinsons psychosis.

In mild cases of hallucinations, the person may be aware that the images are not real. In these cases, if the hallucinations are not causing any distress, pharmaceutical treatment may not be necessary. Sometimes improved lighting in darkened or shadowy areas may help reduce occurrences.

Sometimes the person may not realize he or she is hallucinating. In these cases, especially if the hallucinations are severe and disturbing, a doctor may recommend adjustments to the persons current Parkinsons medications. However, this could potentially worsen movement-related Parkinsons symptoms. If these symptoms affect the persons quality of life, a doctor may instead recommend antipsychotic drugs, particularly clozapine or quetiapine, which typically help reduce hallucinations without affecting other Parkinsons symptoms.

Parkinsons Disease And Psychosis: Hallucinations Delusions

Parkinsons disease psychosis occurs in around 50% of PD patients. In Parkinsons disease, hallucinations and confusion are relatively common, often occurring as side-effects of Parkinsons medications. These symptoms can also be indicative of Parkinsons disease psychosis, however, so its important to consult your doctor if you think you might be delusional or psychotic. In the meantime, here is everything you need to know about Parkinsons disease psychosis, including symptoms and treatment.

Volunteer To Help Out

Everyday responsibilities like shopping, cooking, and cleaning become much more difficult when you have a movement disorder. Sometimes people with Parkinsons need help with these and other tasks, but they may be too proud or embarrassed to ask for it. Step in and offer to run errands, prepare meals, drive to medical appointments, pick up medications at the drug store, and help with any other day-to-day tasks they have difficulty with on their own.

What Should I Do When My Loved One Is Experiencing A Hallucination

Identifying and Assessing Psychosis in Patients With ...

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 Are They Treated

Your medical team should be aware of non-motor issues, just like your physical symptoms. Internists, neurologists, and psychiatrists together can help determine the right course for each person.

There are antipsychotic medications that are safe and can help to reduce the symptoms of Parkinson’s disease psychosis, but there are even more antipsychotics that are contraindicated for PD.

Let a medical provider know you have Parkinson’s when seeking emergency care or treatment for something by doctors who are not a part of your regular medical team.

There is only one drug, pimavanserin, approved in 2016 by the FDA specifically for PD. It has a mechanism of action that doesn’t block dopamine. This has made it a safer drug for people with Parkinson’s.2

Two other medications, quetiapine and clozapine, that have been used for a longer time, are also considered safe for treating hallucinations and delusions in people with PD.2

Why Isnt There A Greater Awareness Of Parkinsons Disease Psychosis

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. You can find more information on the non-motor symptoms associated with Parkinsons disease here.

Parkinson’s Disease Psychosis

Most patients reported having hallucinations for at least one year, the researchers wrote. A difference noted: Parkinsons patients tended to see images of people and animals not actually present, while dementia patients tended to experience people or presence hallucinations.

Patients were asked about their experiences and interpretations of such hallucinations, their impact on relationships and daily life, and information or support they had asked for or received regarding them.

Caregivers were asked to reflect upon their own reactions and any support they might have received.

All patients were assessed for vision, cognition, and motor function skills.

Differences in the VH experience between persons with dementia and PD were less striking than the overall similarities across conditions at equivalent stages of cognitive and insight impairment, the researchers wrote.

Patients reported disease aspects such as loss of independence and depression as more concerning and difficult than hallucinations, while those with poorer cognitive abilities voiced greater distress with visual hallucinations.

Three overall themes emerged in the study:

An ability to understand and distinguish a visual hallucination from reality called insight by the research team influenced how the threat of such hallucinations was perceived and whether acceptance occurred over time. Reactions to visual hallucinations and coping strategies varied as insights changed with disease progression.

Age And Duration Of Illness

Increased age has been associated with the presence of hallucinations. This might be explained by accerelated sensory loss or age related side effects of medication. One of the main confounders with age is duration of illness when the non-independence of these variables was controlled, Fnelon et alfound that duration of illness was the crucial factor. Grahamet al identified two subgroups of patients with Parkinsons disease experiencing hallucinosis: in those with disease duration of 5 years or less, visual hallucinations were associated with rapid progression of the motor but not the cognitive component of the disease. In the remainder with longer histories, visual hallucinations were associated with postural instability, global cognitive impairment, and the lack of depression. Goetz et al contrasted patients with Parkinsons disease who experienced hallucinations within 3 months of levodopa therapy with those who experienced hallucinations after 1 year of treatment. Diagnoses in the early onset group more often changed to Lewy body or Alzheimers disease. Lewy bodies are present to a greater or lesser degree in all cases of Parkinsons disease and are known to be associated with visual hallucinations.

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 Causes Psychosis In Parkinsons

Currently, there is not a clear understanding of the exact cause of Parkinsons disease psychosis, although certain brain chemicals and receptors are believed to play a role. In general, the condition is believed to be caused by either one of the following:

Side effect of dopamine therapy:

Although an exact causal relationship has not been established, some believe that this condition may be a side effect of dopaminergic therapy .2Dopaminergic therapy increases dopamine levels, helping improve motor symptoms in patients with Parkinsons disease. However, increasing dopamine levels can also cause chemical and physical changes in the brain that inadvertently lead to symptoms such as hallucinations or delusions.

Natural outcome of the disease:

This condition can be triggered by changes in the brain that occur regardless of taking dopamine enhancing medication. Some of these changes occur naturally as Parkinsons disease progresses.2

What Types Of Hallucinations Can People With Parkinsons Experience

Parkinson

Visual hallucinations are the most common in Parkinsons disease. Auditory hallucinations occur mainly in depression. Tactile or olfactory sensations are unusual.

Often the symptom starts with lively dreams, then illusions, then hallucinations at night-time. After that hallucinations can also appear in the day. Initially the patient understands that the experience is a hallucination, but if things progress it becomes difficult to say what is real and not.

Further progression could mean that the hallucinations become scary, and patients can develop confusion or delusions . Auditive hallucinations are seldom linked to Parkinsons.

Mild hallucinations do not need to impact life very much, and can even be experienced as entertaining in some cases. But when the hallucinations become more pronounced and it is difficult to differentiate them from reality, they can have a big effect.

Parkinsons Disease Psychosis: Hallucinations Delusions And Paranoia

As part of Parkinsons Disease and its treatment, hallucinations, illusions, delusions, suspiciousness and paranoid behaviors occur in over 50% of patients. In this 1-hour webinar Dr. Christopher Goetz suggests lifestyle changes, medication adjustments and a recently FDA approved drug to specifically treat psychosis in Parkinsons Disease.

What Treatments Are Available For Parkinsons Psychosis

Your doctor may first reduce or change the PD medication youre taking to see whether that reduces psychosis symptoms. This is about finding a balance.

People with PD may need higher doses of dopamine medication to help manage motor symptoms. But dopamine activity shouldnt be increased so much that it results in hallucinations and delusions. Your doctor will work with you to find that balance.

Dr. Evidente gives a clear description on differences in PD dementia, Alzheimers and other dementias.

Predictive Factors And Pathophysiology

Psychosis in Parkinson’s Disease Patients

Minor hallucinations/illusions

Patients with isolated minor hallucinations/illusions differed from patients without hallucinations only by the presence of more depressive symptoms on the CES-D rating scale, suggesting that depressive symptoms are a facilitating factor. Indeed, depression may sometimes trigger or aggravate hallucinations associated with deafness or ocular pathology . However, when we analysed depression according to CES-D cut-off scores, the difference between the Parkinson’s disease patients with minor hallucinations/illusions and those with no hallucinations was not significant. Interestingly, hallucinations involving the deceased spouse have been reported in up to half of widowed persons, with a higher frequency in the elderly . In the present study, the `presence’ was that of a deceased relative in only three cases bereavement cannot therefore explain the bulk of the cases.

Dopaminergic agents and other treatments

In the present study, non-hallucinators were more likely to be on anticholinergics or selegiline than patients with hallucinations. A similar paradoxical, negative association between anticholinergics and hallucinations was found by Sanchez-Ramos and colleagues . This reflects the recommendation whereby the use of these drugs in patients with cognitive impairment is avoided because of the well-known risk of cognitive worsening and/or hallucinations in this population.

Section Header Managing Psychosis With Medication

Dont keep hallucinations or delusions a secret from your doctor. Medications — or changes to the medications you take — can help manage Parkinsons psychosis.

Streamlining your meds. The first thing your doctor may want to do is stop or lower your Parkinsons medication dose. They may boost dopamine levels in your brain. That improves motor symptoms but can also cause changes in your emotions or the way you act.

Antipsychotics. These medications balance your brain chemicals. Only a few are considered safe for people with Parkinsons disease. These include quetiapine and clozapine .

Pimavanserin . Another antipsychotic, this first-in-class drug was approved by the FDA in 2016 to treat hallucinations and delusions in Parkinsons disease linked with psychosis.

If you see a doctor who isnt part of your usual care team — say, in the emergency room or an urgent care setting — tell them you have Parkinsons disease and what medications you take for it.

Abstract

1. Introduction

Nonmotor symptoms have an important impact on quality of life in PD patients and their caregivers and are largely recognized as such by a growing number of health care providers . Psychosis is recognized as one of the most frequent and disabling nonmotor symptoms in PD with prevalences of 20% up to 70% in advanced stages of the condition . Its relevance is such that it has even been named as the main feature of one of the seven proposed nonmotor subtypes of PD described by Sauerbier et al. . In this review we aim at providing an up to date practical approach to psychosis in PD, with especial emphasis on clinical subtypes and pathophysiological mechanisms underlying this condition with the aim of leading to better intervention strategies in the nearer future.

2. Defining PD Psychosis

2.1. History

Currently, under various searching terms on psychotic symptoms in PD, including the terms hallucinations, psychotic symptoms, illusions, delusions, and misperceptions among others, over 4000 articles and reviews can be found, dated back as far as 1945 in the current literature , being the first description found in a book published in 1921.
