Why Does Parkinson’s Cause Hallucinations

I Had A Hallucination: What Next

Parkinson’s Disease Psychosis

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 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.

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.

Treatment And Management Of Hallucinations

You should discuss any hallucinations or delusions with your doctor, or Parkinsons nurse if you have one, so that all treatment options can be considered.

In mild cases no specific action may be required and simple reassurance that the images, sensations or sounds are harmless may be all that is needed.

How Can I Get Help

3 Causes of Psychosis in Parkinson

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.

Treatment Not A Must Early On

Typically, people with PD who develop psychosis dont do so until five to 10 years into their disease course, Dr. Hui says. For some, particularly early on, mild psychosis symptoms may be manageable without treatment. If the hallucinations are very mild and fleeting, we may not treat it if the patient is aware it is not real and can pretty much ignore them, she explains. We start treating when hallucinations become more severe or scary, like seeing attackers, or thinking someone is breaking in, and it interferes with activities of daily living or is emotionally distressing.

Recognising And Verifying Signs Of Hallucinations In Those Living With Dementia

It can be difficult to know when a person with dementia is experiencing perceptual difficulties or hallucinations. It can appear that a person is experiencing hallucinations where there may be some other explanations. For instance, if the person is claiming to have a strange or unpleasant taste in their mouth it could be that theyre overdue a dental check-up or, if they wear dentures, that they are causing discomfort or are ill-fitting. It could even be due to the particular brand of toothpaste that theyre using. When it comes to visual or auditory perception, the person may need a hearing or sight check and in addition, it should be confirmed that any equipment they use, such as glasses or hearing aids, are clean and functioning. As pointed out by Dementia UK, practical actions such as these constitute simple ways to help prevent misperceptions and hallucinations.

In such circumstances, it may be helpful for you to face the person and explain that youll go first to show them that its safe. Reassuring the person while holding their hands and slowly walking backwards will hopefully help them to begin crossing the perceived obstacle with you. Maintaining eye contact and vocally reassuring the person should help them to trust what youre saying and encouraging them as you progress should mean that the incident will be quickly forgotten. It is important to explore potential reasons for different signs of hallucinations and to seek medical advice where necessary.

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 Causes Psychosis In Parkinsons

What are the causes of Parkinson’s disease? Are there disorders that have similar symptoms?

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

Types Of Hallucinations In People With Parkinsons Disease

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:

Showing Up As Your Best Self

Caring for someone with a progressive condition like Parkinsons disease can be challenging. Hallucinations only add to the stress of caregiving, especially if the person youre caring for doesnt have insight into what theyre experiencing.

The more you understand about your loved ones condition, the easier itll be to care for them. Talk to their doctor and read up on Parkinsons disease so youre better equipped to respond when hallucinations occur.

Dont forget to take care of yourself as well. Take regular breaks from caregiving to relax and do the things you enjoy. By tending to your own needs, youll have more energy to devote to your loved one.

Selfcare For The Person With Parkinsons

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.

The Bottom Line On Pd Psychosis

While it can be tricky to balance treating your motor symptoms of Parkinsons disease with treating symptoms like psychosis, working closely with your health care team can help you find the right combination of medications and lifestyle management skills for you. And remember: As with many aspects of this disease, early intervention is best. Psychosis in Parkinsons disease is something that, as providers and family members, important to screen for early on so we can monitor it, says Dr. Pan.

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.

Depression, Anxiety and Psychosis in 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

Talk About Your Hallucinations And Delusions

Your hallucinations or delusions can be distressing for those around you. They may be unsure how to react so let them know what you are going through and how best they can help you. They will be more able to support you if you share your experiences with them, particularly if you know what the most common triggers are and what can be done to make the hallucinations or delusions go away.

Counselling can sometimes be helpful, particularly if the hallucinations or delusions strain relationships. Your doctor will be able to advise on the available types of counselling.

How To Care For Someone Who Experiences Delusions

If the person youre caring for experiences confusion or delusions, heres what you can do in the moment:

  • Stay as calm and patient as you can and remember that this belief has nothing to do with you and only with what is going on in their mind
  • Remove any objects in the room that could pose a danger to them or to anyone else
  • Clear space so there are no tripping hazards and its easy for the person to move around
  • Do not try to reason with the person or convince them why their belief is false
  • Reassure them that everything is going to be okay
  • If the person becomes aggressive, minimize your movements and remain calm
  • Ask the person to talk to you about what they are feeling and really listen to them so they dont feel threatened
  • If you feel like you or they are in danger, call 911

Here are a few actions you can take once the delusion has passed:

  • Inform their doctor immediately
  • Educate others who may care for the person how to handle the situation if it happens
  • If the person is open to it, discuss it with them and ask them to explain what the experience is like for them and if theres anything different you could do next time
  • Seek expert advice if you feel like you need support in managing these episodes

What Is A Hallucination

A hallucination is a perception of something that does not actually exist. This may be visualised, heard, felt, smelled or tasted. Hallucinations are sometimes confused with illusions, which are distortions of a reality rather than something that is purely imagined – as with hallucinations.

Visual hallucinations: In Parkinson’s, hallucinations are most commonly visual and may be in black and white, in colour, still or moving. Often the images involve small animals and children. They may disappear quickly or may last for some time.

Auditory hallucinations: auditory hallucinations are less common. These generally involve hearing voices or other familiar sounds. Auditory hallucinations can also be part of a depressive symptomatology.

Tactile hallucinations: hallucinations may be tactile, that is, you may feel a sensation, like something touching you.

Smell and taste hallucinations: less commonly you may feel that you can taste something you havent eaten, or you may smell something that is not present, such as food cooking or smoke.

Usually hallucinations are not threatening or distressing. If you hallucinate you may be unaware that your perceptions are not real, and sometimes imagined images or sensations can be comforting. But hallucinations can also be distressing and you may feel threatened or frightened and may need reassurance and comfort from those around you.
