Managing Psychotic Symptoms In Parkinsons Disease

Any psychotic symptoms, such as hallucinations, delusions, or paranoia, that are experienced by a person with PD should be reported to a doctor, even if the symptoms are not bothersome. Managing these symptoms may include reducing or withdrawing the use of PD medications that may be causing the symptoms or adding an antipsychotic medication.1,2

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.

What Is A Delusion

A delusion is a thought or belief that is not based on reality, as opposed to a hallucination which involves seeing, hearing, tasting or feeling things that do not exist.

People who experience delusions may be convinced that they are true, even though they are irrational – for example paranoia – that someone is trying to cause them harm or that there is a conspiracy against them. Delusions can be difficult to overcome, particularly if they involve a carer or other close contact, as they may provoke suspicion, mistrust or jealousy and so strain relationships. Severe delusions can cause anxiety or irritability, especially if the person finds it difficult to tell whether things are real or not.

Some people with Parkinson’s experience a mixture of delusions, hallucinations and illusions which may make them feel confused and impact on daily life.

Other Symptoms Of Parkinsons Disease

Psychosis in Parkinsons  why it happens to your patients ...

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:

What Are Hallucinations Like With Parkinsons

Hallucinations are when you see, hear, or feel things that arent actually there, explains Jennifer S. Hui, M.D., a neurologist with Keck Medicine of University of Southern California in Los Angeles. They can run the gamut in terms of how they manifest in different people with psychosis. In Parkinsons psychosis specifically, hallucinations tend to share some common characteristics.

Typically, hallucinations in Parkinsons patients are very specific, explains Ling Pan, M.D., clinical assistant professor of neurology and neurosurgery at NYU Langone Health in New York City. They are visual hallucinations, often of small animals or objects, strangers in the home, or seeing family members who arent there, whether living or deceased.

Earlier on in the disease, visual hallucinations may be milder. They may be more like illusions, rather than a fully formed hallucination, she adds. For example, patients may see a shape morphing on the floor or think they see something passing by them.

While researchers still dont know why psychosis can occur with Parkinsons, medications for the condition can sometimes play role. If we are treating with dopamine agonists, these can sometimes lead to hallucinations and be a culprit in worsening that symptom if you are already prone to it and if your Parkinsons disease is enough to cause that symptom to manifest, says Dr. Hui.

Families Often See The Signs First

Often, loved ones or close family members may notice the signs of psychosis in Parkinsons disease first. Diagnosis is based on history, often with patients families reporting that symptoms are occurring, says Dr. Hui. To confirm the diagnosis, your doctor will consider a variety of diagnostic criteria, such as which specific symptoms are present and when they began, as well as ruling out other potential causes, according to a study in Parkinsons Disease.

What Are The Primary Motor Symptoms Of Parkinsons Disease

Hallucinations with Parkinson’s

There are four primary motor symptoms of Parkinsons disease: tremor, rigidity, bradykinesia and postural instability . Observing two or more of these symptoms is the main way that physicians diagnose Parkinsons.

It is important to know that not all of these symptoms must be present for a diagnosis of Parkinsons disease to be considered. In fact, younger people may only notice one or two of these motor symptoms, especially in the early stages of the disease. Not everyone with Parkinsons disease has a tremor, nor is a tremor proof of Parkinsons. If you suspect Parkinsons, see a neurologist or movement disorders specialist.

How Commonly Do Parkinsons Disease Patients Develop Psychosis

Psychosis in Parkinsons disease generally comes in two forms: hallucinations or delusions . When hallucinations occur, they are mostly visual . Sometimes, they can be threatening, but this is less common. Auditory hallucinations are rare in Parkinsons disease and if they do occur, they are usually accompanied by visual hallucinations.

Delusions are usually of a common theme, typically of spousal infidelity. Other themes are often paranoid in nature Because they are paranoid in nature, they can be more threatening and more immediate action is often necessary, compared to visual hallucinations . It is not uncommon that patients actually call 9-1-1 or the police to report a burglary or a plot to hurt them.

Unfortunately, psychosis occurs in up to 40% of Parkinsons disease patients . In the early stage of Parkinsons disease psychosis, the patient often still has a clear understanding and retains their insight, but this tends to worsen over time and insight may eventually be lost. At later stages, patients may be confused and have impaired reality testing that is, they are unable to distinguish personal, subjective experiences from the reality of the external world. Psychosis in Parkinsons disease patients frequently occurs initially in the evening, then later on spills into the rest of the day.

Pd Medications May Lead To Psychosis

If Parkinsons disease is primarily a movement disorder, then why might psychosis occur? For some people, PD drugs may be the culprit, causing unwanted neurological effects. Many of our medications can exacerbate and cause psychosis, explains Dr. Hui. Many Parkinsons meds work by increasing dopamine in the brain, which can help with movement symptoms of PD. But that same dopamine can also stimulate areas in the brain that lead to psychosis symptoms like hallucinations and delusions, according to the Michael J. Fox Foundation for Parkinsons Research.

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

Network Changes And Thalamic Drivers

Ask the MD: Parkinson

Visual hallucinations have fascinated neurologists and neuroscientists for many years, with their tantalisingly rich and often narrative detail. Due to their transient nature, they have been challenging to investigate, with no clear mechanism found, but many theories have been proposed. Previous models for visual hallucinations considered them as cortical release phenomena, where spontaneous activity occurs in the absence of visual stimuli. Alternative models suggested that hallucinations arise due to incorrect binding of objects into visual scenes.

Advances in computational modelling and network neuroscience have opened up approaches to understanding the brain in new ways. Recent models suggest that Parkinsons hallucinations could arise due to a shift in dominance of difference networks. Specifically, there is thought to be a breakdown in those networks directed to attention and perception, and overactivity of the default mode network ,, a large-scale network that becomes activated during rest, and in day dreaming and mind-wandering. Indeed abnormal levels of default mode network activation are seen in patients with Parkinsons hallucinations.

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.

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.

Diagnosis And Treatment Of Hallucinations

First, your doctor needs to find out what’s causing your hallucinations. They’ll ask about your medical history and do a physical exam. Then they’ll ask about your symptoms.

They may need to do tests to help figure out the problem. For instance, an EEG, or electroencephalogram, checks for unusual patterns of electrical activity in your brain. It could show if your hallucinations are due to seizures.

You might get an MRI, or magnetic resonance imaging, which uses powerful magnets and radio waves to make pictures of the inside of your body. It can find out if a brain tumor or something else, like an area that’s had a small stroke, could be to blame.

Your doctor will treat the condition that’s causing the hallucinations. This can include things like:

  • Medication for schizophrenia or dementias like Alzheimer’s disease
  • Antiseizure drugs to treat epilepsy

How Caregivers Can Cope With Parkinsons Related Psychosis

As a caregiver, you might struggle to cope when your loved one insists that their hallucination or delusion is real. That said, you dont have to fight every battle. When reasonable, it might be better to not always contradict your loved one when the hallucinations or delusions are fairly fixed, because that can just become a point of contention and argument that increases the stress for both the patient and caregiver, says Barrett.

For example, if your loved one is falsely accusing you of cheating or stealing from them, you might want to correct them. But if they mistake a lamp for an animal or see a monkey in the backyard and they arent bothered by it, resist the urge to correct them just for the sake of correctness. If they want to know, Is that real or not? then of course you can clarify, says Barrett. But if theyre not bothered or upset by their hallucinations, its OK sometimes to just let it be.

However, if the psychosis is bothersome and interfering with your loved ones care, help them talk with their doctor about treatments that could help.

And above all else, remember to take care of yourself. Research published in 2015 in Parkinsonism & Related Disorders shows that psychosis is particularly burdensome for caregivers of people with Parkinsons disease. If thats the case, dont hesitate to lean on others, such as your family members or hired help, for support.

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

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.
