Hallucinations And Delusions In Parkinsons

Some people with Parkinsons may experience hallucinations or delusions. This means that they may see, hear, smell or taste things that arent there, or have thoughts and beliefs that arent based on reality.

Hallucinations and delusions are more common in people who have had Parkinsons for a long time, though they can affect both younger and older people.

These symptoms may be caused partly by Parkinsons and partly by some Parkinsons medication.

Whilst medications for hallucinations and delusions are available they often only have limited effect in Parkinsons.

Pharmacologic Therapies For Gait And Balance Dysfunction

New : Get the most of your medication

With disease progression, PD patients may develop abnormalities in posture, balance, and gait, which stem from complex interrelated mechanisms involving cortical and brainstem motor circuitry and cognitive dysfunction. Such symptoms cause cumulative impaired mobility, functional deterioration, and poor HRQoL . Gait and balance impairment is challenging to treat due to poor response to dopamine replacement . This unmet therapeutic need has led to exploration of nondopaminergic pathways and neural substrates as potential targets for drug development, and include the A2AR antagonist istradefylline the cholinergic pathway agents varenicline, TAK-071, and rivastigmine noradrenaline uptake inhibitors atomoxetine and methylphenidate and high-dose vitamin D supplementation .

Safinamide Negative Side Effects

Because of negative side effects, 3.7 percent of participants taking safinamide dropped out of clinical trials as compared with 2.4 percent of those taking a placebo.

Common adverse effects observed during these clinical trials included the following:

  • jerky or fragmented motions

Of these symptoms, dyskinesia was about twice as common in people taking safinamide as compared with those not taking it .

Less common but more serious adverse effects include the following:

  • worsening high blood pressure
  • visual hallucinations and psychotic behavior
  • falling asleep during the day
  • serotonin syndrome
  • problems with impulse control or compulsive behavior
  • fever and confusion

Here are some drugs that you shouldnt take if youre also taking safinamide:

  • certain antidepressants
  • cyclobenzaprine
  • St. Johns Wort

Although people with kidney impairment can take safinamide, those with severe liver problems should not take the drug.

What Future Medications May Be Available For Parkinsons

There are numerous studies investigating new treatments for Parkinsons disease.

There has been new information about the role of autoimmunity and T-cells in the development of Parkinsons disease, possibly opening the door to a role for biologics.

Stem cells are also being investigated as a treatment option for Parkinsons disease.

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 Parkinsons, 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.

Promising New Medication For Parkinsons

Parkinson’s Disease and Medication: Whats New?

NLX-112 has shown promising results in the lab for reducing dyskinesia caused by the medication Levodopa, which is a common and distressing side effect of current Parkinsons medications. Dyskinesia causes involuntary movements that can affect various parts of the body, making simple, everyday tasks like tying your shoelaces difficult.

The clinical trial aims to assess whether NLX-112 is safe and well-tolerated by people suffering from Parkinsons who also experience dyskinesia. It will also analyse how the drug can reduce dyskinesia and other non-motor symptoms such as depression and disturbed sleep.

Adrian Newman-Tancredi, PhD, DSc, Chief Executive Officer of Neurolixis, commented: We are delighted that this important trial is now underway, and the first participant has been recruited. The pandemic has made getting to this point more challenging and time-consuming than wed hoped, but were now keen to make up for lost time. If recruitment to the study progresses smoothly, we are hopeful that we will have results to share by late 2022.

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.

Full List Of Medications Approved For The Treatment Of Parkinsons Disease In The Usa

Below is a full list of Parkinsons medications that have been approved to treat Parkinsons in the United States. This material is intended to provide you with information. It should not be used for treatment purposes, but rather as a source for discussion with the patients own physician. Work with your physician to determine which medications are best for you, and know the risks and benefits of each.

Patients Should Seek A Medication Review At Least Annually


There have been several exciting recent developments in the realization of advanced treatment options and new medications for Parkinsons disease. From surgical treatments to drug development to a pump that infuses medication to patients throughout the day, individuals with Parkinsons disease may benefit from the latest developments for treatment of PD.

Most patients with Parkinsons disease can be adequately treated the first several years after the disease has begun presenting symptoms with medications that deliver levodopa, used alone or in combination with carbidopa. Later in the disease, individuals with PD may consider highly effective surgical treatments such as Deep Brain Stimulation and/or other medications or combinations of medications to manage their symptoms.

Trey Eskew, a physicians assistant who has treated patients at Neurology Solutions Movement Disorders for the past six years, said that many patients arent aware of the new PD medications that have become available, including several that were released in 2015.

Here are some facts and findings about the latest PD medications.

Current Parkinsons Treatments Cant Slow Down Onset Of Disease

Parkinsons is a long-term degenerative disorder of the central nervous system, which mainly the area of the brain that controls movement leading to a slow onset of symptoms including tremors, rigidity and slow movement.

More than 10 million people worldwide are estimated to be living with Parkinsons disease, according to the US-based Parkinsons Foundation, with the Parkinsons News Today website saying it affects 1,900 per 100,000 among those aged over 80,

Typically, by the time people are diagnosed with the condition, they have already lost between 70% and 80% of their dopamine-producing cells, which are involved in co-ordinating movement.

While current treatments mask the symptoms, there is nothing that can slow down its progression or prevent more brain cells from being lost.

As dopamine levels continue to fall, symptoms get worse and new symptoms can appear.

The Latest Treatment For Parkinsons Disease

Inbrija is the latest treatment for Parkinsons disease. It was approved by the Food and Drug Administration in late 2018 after two decades of research and development. Inbrija is a new form of levodopa that allows systemic delivery of the medication through inhalation, allowing higher doses of medication to enter the bloodstream.

This new drug from Acorda Therapeutics will treat the intermittent symptoms of OFF episodes on demand and comes in the form of a powder capsule and inhaler. Inbrija is the first and only inhaled levodopa medication to be approved for Parkinsons disease by the FDA. It is available by prescription through your doctor.

The Michael J. Fox Foundation helped to fund the early development of this new treatment for Parkinsons disease due to the impact OFF periods have on patients lives.

Hallucinations And Rem Sleep Disorders In Parkinsons 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 Common Is Parkinsons Disease Psychosis

Trial of new treatment for Parkinson’s disease | 7.30

Between 20-40% of people with Parkinsons report the experience of hallucinations or delusions. When followed as the disease progresses over the years, this number increases. The increase does not mean that the hallucinations are persistent across the majority of patients. However, it is important to note that these statistics sometimes include delirium, in which the symptoms are temporary due to medication that needs to be adjusted or infection that needs to be treated, and isolated minor symptoms or minor hallucinations, including illusions, where instead of seeing things that are not there , people misinterpret things that are really there. These are the most common types of psychosis in people with PD, with different studies placing the occurrence between 25-70% of people with Parkinsons. Typically, if the person with PD only has these minor hallucinations, their doctor will not prescribe an antipsychotic medication, though more significant psychosis that requires medication may develop over time. In one study, 10% of those with minor hallucinations had their symptoms resolved within a few years, while 52% saw their symptoms remain the same and 38% saw their psychosis symptoms get worse.

We recommend that people with Parkinsons not use a single percentage to represent the prevalence of hallucinations and PDP. Parkinsons is a complex disease and as it progresses the percentages and risk of symptoms will change.

Medication For Parkinsons Disease

Once the doctor diagnoses Parkinsons disease, the next decision is whether a patient should receive medication, which depends on the following:

  • The degree of functional impairment

  • The degree of cognitive impairment

  • Ability to tolerate antiparkinsonian medication

  • The advice of the attending doctor

No two patients react the same way to a given drug, therefore, it takes time and patience to find an appropriate medication and dosage to alleviate symptoms.

Important Points About The New Medications

With multiple new medications available for the treatment of PD, there is more hope than ever that Parkinsons symptoms can be successfully managed for many years. A few things to consider:

  • For people whose symptoms are difficult to control, these new treatments are welcome additions to what was previously available and many people with PD have been using these new medications with significant benefit.
  • On the other hand, many of the newly-approved medications have the same mechanisms of action as older medications so they are not breaking new ground in treating symptoms.
  • In addition, for some people, the effect on symptoms may be mild or not substantial.

These caveats may mean that your physician has not suggested a medication change for you. It is also important to note that despite all the new medications, carbidopa/levodopa remains the most potent medication to treat the motor symptoms of PD.

If your doctor does choose to try one of the new options, there may be multiple paths that your doctor can take when contemplating a medication adjustment. Often trial and error is the only way to determine the best medication regimen for you, so you may need to practice some patience as you work together with your doctor to determine what works or doesnt work.

What New Treatments Are Being Developed

Thanks to the progress weve already made, new treatments are being tested in clinical trials that have the potential to slow, stop or even reverse Parkinsons.

These include:

  • stem cell therapies, which aim to use healthy, living cells to replace or repair the damage in the brains of people with Parkinsons
  • gene therapies, which use the power of genetics to reprogramme cells and change their behaviour to help them stay healthy and work better for longer
  • growth factors , which are naturally occurring molecules that support the growth, development and survival of brain cells.

And were developing treatments that aim to improve life with the condition, including new drugs that can reduce dyskinesia.

Abbvie Submits New Drug Application To Us Fda For Investigational Abbv

Parkinsons disease, treatments and symptoms.
  • If approved, ABBV-951 will offer patients the first continuous subcutaneous delivery of carbidopa/levodopa prodrugs
  • Submission is supported by Phase 3 study that demonstrated patients had significant increases in hours of “On” time without troublesome dyskinesia, compared to oral immediate-release carbidopa/levodopa

NORTH CHICAGO, Ill., May 20, 2022 /PRNewswire/ — AbbVie today announced that it has submitted a New Drug Application to the U.S. Food and Drug Administration for ABBV-951 for the treatment of motor fluctuations in patients with advanced Parkinson’s disease .

The submission is based on results from a Phase 3, head-to-head, randomized and controlled clinical trial demonstrating statistically significant improvement in “On” time without troublesome dyskinesia compared to oral immediate-release carbidopa/levodopa .

ABBV-951 is designed to provide a first-of-its-kind, 24-hour, continuous subcutaneous delivery of CD/LD. Compared to oral CD/LD, it offers the potential for improvement in motor fluctuations in patients with advanced Parkinson’s disease, a progressive and chronic neurological disorder resulting from the loss of dopamine-producing brain cells,1 which primarily manifests with tremor, muscle rigidity, slowness of movement and difficulty with balance. In PD, patients and their healthcare providers share the same goal: to extend the amount of “On” time, referring to the period when symptoms are well controlled without dyskinesia or involuntary movements.
