Hallucinations And Rem Sleep Disorders In Parkinson’s Disease
At timestamp 1:58 in this recording of Thrive: HAPS 2020 Caregiver Conference, you will find a one hour talk by neurologist Joohi Jimenez-Shahed, MD. In it she delves into what REM sleep behavior disorder is and is not, and the distinctions between hallucinations, delusions, and delirium. Managment options for RBD and hallucinations are included.
How Is Psychosis Managed
The urgency of treatment will depend on the type and characteristics of psychosis. Sometimes, when the hallucinations are mild and benign, and insight is retained, it is best that the Parkinson regimen be kept as is. However, when a patient is experiencing more threatening paranoid delusions, then more aggressive treatment is warranted .
The management of psychosis includes:

Side Effects And Problems With Levodopa
In the early days of taking levodopa, you may feel sickness or nausea. In most people this will pass as your body adjusts to the medication.
Overtime as Parkinsons progresses the levodopa dose will need to be adjusted. Many people will become more aware that symptoms sometimes return between doses of medication. This is called wearing off and is a sign your dose needs to be adjusted.
As levodopa is absorbed through the gut, constipation or other stomach problems may impact on uptake of the medication. In some people who have had Parkinsons for sometime extra involuntary movements can occur. Your neurologist will be able to help adjust medications to minimise dyskinesia.
Other side effects may include:
- Confusion
- Psychological changes
- Sleepiness, fainting or dizziness
Side effects of levodopa can sometimes be improved by changing your dose, the form of the drug or how often you take it. If this doesnt work, other types of drug may be combined with levodopa.
Speak to your GP or specialist about the right treatment for you.

How Anticholinergics Are Used
These medications are older and are not used very often for Parkinsons today. Sometimes they are prescribed for reducing tremor and muscle stiffness. They can be used on their own, especially in the early stages of your Parkinsons when symptoms are mild, before levodopa is prescribed.
Anticholinergics can also be used with levodopa or a glutamate antagonist. They are taken as tablets or as a liquid.

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.
When Should I See My Healthcare Provider Or When Should I Seek Care
You should see your healthcare provider as recommended, or if you notice changes in your symptoms or the effectiveness of your medication. Adjustments to medications and dosages can make a huge difference in how Parkinsons affects your life.
When should I go to ER?
Your healthcare provider can give you guidance and information on signs or symptoms that mean you should go to the hospital or seek medical care. In general, you should seek care if you fall, especially when you lose consciousness or might have an injury to your head, neck, chest, back or abdomen.

Psychosis: A Mind Guide To Parkinsons
Can be downloaded as a PDF or ordered the Parkinson’s Foundation online store. This 40-page booklet is a thorough guide to all aspects of Parkinsons psychosis, including symptoms, causes, treatment options, coping strategies for both the family and person experiencing the psychosis, and a chapter on tips for caregivers.
What Medications And Treatments Are Used
Medication treatments for Parkinsons disease fall into two categories: Direct treatments and symptom treatments. Direct treatments target Parkinsons itself. Symptom treatments only treat certain effects of the disease.
Medications
Medications that treat Parkinsons disease do so in multiple ways. Because of that, drugs that do one or more of the following are most likely:
Several medications treat specific symptoms of Parkinson’s disease. Symptoms treated often include the following:
- Erectile and sexual dysfunction.
- Hallucinations and other psychosis symptoms.
Deep brain stimulation
In years past, surgery was an option to intentionally damage and scar a part of your brain that was malfunctioning because of Parkinsons disease. Today, that same effect is possible using deep-brain stimulation, which uses an implanted device to deliver a mild electrical current to those same areas.
The major advantage is that deep-brain stimulation is reversible, while intentional scarring damage is not. This treatment approach is almost always an option in later stages of Parkinson’s disease when levodopa therapy becomes less effective, and in people who have tremor that doesnt seem to respond to the usual medications.
Experimental treatments
Researchers are exploring other possible treatments that could help with Parkinsons disease. While these arent widely available, they do offer hope to people with this condition. Some of the experimental treatment approaches include:

Who Is At Risk For Psychosis
Theres no predicting with certainty which patients with Parkinsons disease will go on to develop symptoms like hallucinations or delusions. A number of risk factors both internal and external- are associated with the condition.Some of these risk factors include: age, duration and severity of Parkinsons disease and the taking of dopamine therapy.3-6
Parkinsons Disease Psychosis: The What When Why And How
Psychosis is a psychiatric term used in neurology to refer to a spectrum of abnormalities. Parkinsons disease psychosis is where people experience hallucinations or delusions. Hallucinations is seeing, hearing, or smelling things that dont exist. With tactile hallucinations, one can feel a presence that isnt there. Delusions are believing something that is not true, like that a spouse is being unfaithful or caregivers are stealing. In this one-hour talk, movement disorder specialist Christopher Goetz, MD, focuses on hallucinations and spends a little time on delusions.

What Happens In Pdd
People with PDD may have trouble focusing, remembering things or making sound judgments. They may develop depression, anxiety or irritability. They may also hallucinate and see people, objects or animals that are not there. Sleep disturbances are common in PDD and can include difficulties with sleep/wake cycle or REM behavior disorder, which involves acting out dreams.
PDD is a disease that changes with time. A person with PDD can live many years with the disease. Research suggests that a person with PDD may live an average of 57 years with the disease, although this can vary from person to person.

What Is Parkinsons Disease
Parkinsons disease is a condition where a part of your brain deteriorates, causing more severe symptoms over time. While this condition is best known for how it affects muscle control, balance and movement, it can also cause a wide range of other effects on your senses, thinking ability, mental health and more.
What Can I Expect If I Have This Condition
Parkinsons disease is a degenerative condition, meaning the effects on your brain get worse over time. However, this condition usually takes time to get worse. Most people have a normal life span with this condition.
You’ll need little to no help in the earlier stages and can keep living independently. As the effects worsen, youll need medication to limit how the symptoms affect you. Most medications, especially levodopa, are moderately or even very effective once your provider finds the minimum dose you need to treat your symptoms.
Most of the effects and symptoms are manageable with treatment, but the treatments become less effective and more complicated over time. Living independently will also become more and more difficult as the disease worsens.
How long does Parkinsons disease last?
Parkinsons disease isnt curable, which means its a permanent, life-long condition.
Whats the outlook for Parkinsons disease?
Parkinson’s disease isn’t fatal, but the symptoms and effects are often contributing factors to death. The average life expectancy for Parkinson’s disease in 1967 was a little under 10 years. Since then, the average life expectancy has increased by about 55%, rising to more than 14.5 years. That, combined with the fact that Parkinson’s diagnosis is much more likely after age 60, means this condition doesn’t often affect your life expectancy by more than a few years .

Drugs For Parkinsons: The Shocking Side Effects
There are 2 main categories of drugs for Parkinsons Disease, and both have powerful side effects: levodopa, which makes many patients shaky with dyskinesia, and dopamine agonists, which can make turn people into gamblers, sex addicts or hit them with sleep attacks including when theyre driving. This is the story of DA.
At least 1 million people in the US and an estimated 10 million worldwide live with Parkinsons, making it the second most common neurodegenerative disorder . Parkinsons disease, a disorder of the central nervous system, is caused by a degeneration of nerve cells in certain parts of the brain that produce a neurotransmitter called dopamine. Dopamine, commonly known for its role in controlling the brains reward and pleasure center, is partly responsible for starting a circuit of messages that coordinate normal movement.
In the absence of dopamine, the neurons called dopamine receptors in the brains striatum are not adequately stimulated. In simple language, as a persons brain slowly stops producing dopamine, a person has less and less ability to regulate his or her movements, body, and emotions. The result is impaired movement with tremors, slowness, stiffness or balance problems. Lesser known symptoms include depression, apathy and dementia.

Parkinsons Disease And Initial Motor Symptoms
What has been assumed to be primarily a dopamine deficiency in PD is better viewed as a disruption of multiple monoaminergic systems, with dopamine disruption dominating the motor symptoms and serotonin taking a dominant position in Parkinsons disease psychosis .
The classic tale of neurodegeneration in Parkinsons begins with the loss of 50% to 80% of nigral neurons. This stage is when the first traditional motor symptoms appear .
As early motor symptoms become unmanageable, patients are often prescribed levodopa and carbidopa to help restore the dopaminergic tone of the nigrostriatal pathway.
- Levodopa is a dopamine precursor, as likely to be metabolized outside the brain as inside.
- Carbidopa, and other enzyme inhibitors , delay the conversion of levodopa, allowing more of it to pass the blood-brain-barrier for conversion in the brain.
Once in the brain, the exogenous dopamine is used just like the endogenous neurotransmitter, not only resupplying the nigrostriatal pathway and reducing motor symptoms but affecting other residential monoaminergic systems, especially those involved in PDP.
While individuals with late-onset Parkinsons are more susceptible to developing psychotic symptoms, PDP in younger patients can emerge acutely and is associated with concurrent Lewy body dementia.2
What Are The Symptoms
The best-known symptoms of Parkinson’s disease involve loss of muscle control. However, experts now know that muscle control-related issues aren’t the only possible symptoms of Parkinson’s disease.
Motor-related symptoms
Motor symptoms which means movement-related symptoms of Parkinsons disease include the following:
Additional motor symptoms can include:
- Blinking less often than usual. This is also a symptom of reduced control of facial muscles.
- Cramped or small handwriting. Known as micrographia, this happens because of muscle control problems.
- Drooling. Another symptom that happens because of loss of facial muscle control.
- Mask-like facial expression. Known as hypomimia, this means facial expressions change very little or not at all.
- Trouble swallowing . This happens with reduced throat muscle control. It increases the risk of problems like pneumonia or choking.
- Unusually soft speaking voice . This happens because of reduced muscle control in the throat and chest.
Non-motor symptoms
Several symptoms are possible that aren’t connected to movement and muscle control. In years past, experts believed non-motor symptoms were risk factors for this disease when seen before motor symptoms. However, theres a growing amount of evidence that these symptoms can appear in the earliest stages of the disease. That means these symptoms might be warning signs that start years or even decades before motor symptoms.
Non-motor symptoms include:

What Tests Will Be Done To Diagnose This Condition
When healthcare providers suspect Parkinsons disease or need to rule out other conditions, various imaging and diagnostic tests are possible. These include:
- Blood tests .
- Positron emission tomography scan.
New lab tests are possible
Researchers have found possible ways to test for possible indicators or Parkinsons disease. Both of these new tests involve the alpha-synuclein protein but test for it in new, unusual ways. While these tests cant tell you what conditions you have because of misfolded alpha-synuclein proteins, that information can still help your provider make a diagnosis.
The two tests use the following methods.
- Spinal tap. One of these tests looks for misfolded alpha-synuclein proteins in cerebrospinal fluid, which is the fluid that surrounds your brain and spinal cord. This test involves a spinal tap , where a healthcare provider inserts a needle into your spinal canal to collect some cerebrospinal fluid for testing.
- Skin biopsy. Another possible test involves a biopsy of surface nerve tissue. A biopsy includes collecting a small sample of your skin, including the nerves in the skin. The samples come from a spot on your back and two spots on your leg. Analyzing the samples can help determine if your alpha-synuclein has a certain kind of malfunction that could increase the risk of developing Parkinsons disease.
How Should This Medicine Be Used
Rivastigmine comes as a capsule and solution to take by mouth. It is usually taken twice a day with meals in the morning and evening. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any part you do not understand. Take rivastigmine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will start you on a low dose of rivastigmine and slowly increase your dose, not more than once every 2 weeks.
Rivastigmine may improve the ability to think and remember or slow the loss of these abilities but does not cure Alzheimers disease or dementia in people with Parkinsons disease. Continue to take rivastigmine even if you feel well. Do not stop taking rivastigmine without talking to your doctor.
If you are taking rivastigmine oral solution, ask your pharmacist or doctor for a copy of the manufacturers instructions for use. Carefully read these instructions. Always use the oral dosing syringe that comes with rivastigmine solution to measure your dose.Talk to your doctor or pharmacist if you have questions about how to measure your dose of rivastigmine solution.

Number Of People Affected
Parkinsons disease is thought to affect about 2 percent of Americans over 65. Of those, about 50 to 80 percent will go on to develop Parkinsons-related dementia.1 The Parkinsons Foundation estimates that nearly 1 million Americans will be living with Parkinsons by 2020. The disease affects 1.5 times more men than women.7
Approximately 5.8 million Americans are currently living with Alzheimers disease. That number is expected to increase to 14 million by 2050.8 There is little difference between numbers of men and women who develop Alzheimers, but there are more women with the disease, because women tend to live longer than men.3
First Drug Approved For This Indication
WASHINGTON The FDA has approved pimavanserin for the treatment of hallucinations and delusions associated with psychosis experienced by some people with Parkinsons disease, the agency announced Friday.
Hallucinations or delusions can occur in as many as 50% of patients with Parkinsons disease at some time during the course of their illness, the FDA said in a press release.
Hallucinations and delusions can be profoundly disturbing and disabling,Mitchell Mathis, MD, director of the Division of Psychiatry Products in the FDAs Center for Drug Evaluation and Research, said in the release. Nuplazid represents an important treatment for people with Parkinsons disease who experience these symptoms. It is the first drug approved for this indication, the FDA noted.
In a 6-week clinical trial of 199 participants, Nuplazid was found to be superior to placebo in decreasing the frequency and/or severity of hallucinations and delusions without worsening Parkinsons diseases primary motor symptoms.
The drug has a Boxed Warning advising of an increased mortality risk associated with the use of these drugs to treat older people with dementia-related psychosis, which would be an off-label use.
In clinical trials, the most common side effects reported by participants taking Nuplazid were swelling usually of the ankles, legs, and feet due to peripheral edema nausea and confused state.
