What Are The Types Of Parkinsons Hallucinations
Hallucinations can affect any of the five senses:
- Sight . Seeing something that isnt there, such as insects crawling on the walls or a deceased relative.
- Hearing . Hearing voices or sounds that arent real.
- Smell . Smelling an odor that isnt there, like cookies baking or a skunks spray.
- Feeling . Feeling imaginary things, like bugs crawling on your skin.
- Taste . Having a strange taste in your mouth that isnt from something youve eaten or a medical condition.
Some people sense the presence of a person or an animal nearby. Others see real objects transform into other things for example, a vase changes into a dog.
Its more common to have hallucinations at night, when the darkness creates shadows. Hallucinations can last anywhere from a few seconds to a few minutes.
Early in the disease, most people with Parkinsons psychosis have insight, which means they understand that what theyre experiencing isnt real. Later in the disease, often people lose insight and believe that what they see, hear, or feel is real.
What Is Parkinson’s Disease
Parkinsons disease occurs when brain cells that make dopamine, a chemical that coordinates movement, stop working or die. Because PD can cause tremor, slowness, stiffness, and walking and balance problems, it is called a movement disorder. But constipation, depression, memory problems and other non-movement symptoms also can be part of Parkinsons. PD is a lifelong and progressive disease, which means that symptoms slowly worsen over time.
The experience of living with Parkinson’s over the course of a lifetime is unique to each person. As symptoms and progression vary from person to person, neither you nor your doctor can predict which symptoms you will get, when you will get them or how severe they will be. Even though broad paths of similarity are observed among individuals with PD as the disease progresses, there is no guarantee you will experience what you see in others.
Estimates suggest that Parkinsons affects nearly 1 million people in the United States and more than 6 million people worldwide.

What Is Parkinson’s Disease?
Dr. Rachel Dolhun, a movement disorder specialist and vice president of medical communications at The Michael J. Fox Foundation, breaks down the basics of Parkinson’s.
Testing For Parkinsons Disease
There is no lab or imaging test that is recommended or definitive for Parkinsons disease. However, in 2011, the U.S. Food and Drug Administration approved an imaging scan called the DaTscan. This technique allows doctors to see detailed pictures of the brains dopamine system.
A DaTscan involves an injection of a small amount of a radioactive drug and a machine called a single-photon emission computed tomography scanner, similar to an MRI.
The drug binds to dopamine transmitters in the brain, showing where in the brain dopaminergic neurons are.
The results of a DaTscan cant show that you have Parkinsons, but they can help your doctor confirm a diagnosis or rule out a Parkinsons mimic.

Exploring Seven Recently Approved Parkinsons Treatments
Remarkably, in the last five years, seven new medications have been approved for the treatment of the motor symptoms of Parkinsons disease , with two approved in 2020. Thats exciting progress! And while it is great to have so many choices, the various options can be confusing so today I will describe these new medications and their uses.
Using Alternative Medicine For Parkinsons Disease
Conventional medicine and alternative therapy have not been found to stop the progression of Parkinsons disease. If youre interested in using alternative medicine as part of your Parkinsons disease treatment program, talk to your healthcare provider about which alternative therapies might be helpful for you. Self-treating or avoiding or delaying standard care can have serious consequences.

How Do Doctors Diagnose Parkinsonism
No single test exists for doctors to diagnose Parkinsonism.
A doctor will start by taking a persons health history and review their current symptoms. They will ask for a medication list to determine if any medicines could be causing the symptoms.
A doctor will likely also order blood testing to check for underlying potential causes, such as thyroid or liver problems. A doctor will also order imaging scans to examine the brain and body for other causes, such as a brain tumor.
Doctors can perform a test that tracks the movement of dopamine in the brain. This is known as the DaT-SPECT test.
The test uses radioactive markers designed to track dopamine in the brain. This allows a doctor to watch the release of dopamine in a persons brain and identify the areas of the brain that do or do not receive it.
Because Parkinsonism does not respond to typical treatments and can have a variety of symptoms, doctors can have difficulty coming to a quick diagnosis. It may take time for doctors to rule out other conditions and begin to make treatment recommendations.
How Can Caregivers Support Their Loved Ones
Caring for someone who sees, hears, or believes things that arent real can be very difficult. Try to be as patient and calm as you can.
Avoid arguing with the person. If they still have insight, gently explain that what theyre seeing isnt real. Tell anyone who cares for or visits your loved one what to expect, and how to respond.
Stay in close contact with the persons doctor. If their symptoms dont improve, ask whether they need a medication adjustment.
Check whether the person needs hearing aids or glasses. Poor hearing or vision can sometimes lead to hallucinations. It can also help to turn on bright lights at night, to prevent the shadows that may trigger visual illusions.
Secure any dangerous objects, and keep pathways in the home clear to prevent falls and injuries. If you ever feel like the person is a risk to themselves or others, call their doctor.

Other Causes Of Parkinsonism
“Parkinsonism” is the umbrella term used to describe the symptoms of tremors, muscle rigidity and slowness of movement.
Parkinson’s disease is the most common type of parkinsonism, but there are also some rarer types where a specific cause can be identified.
These include parkinsonism caused by:
- medication where symptoms develop after taking certain medications, such as some types of antipsychotic medication, and usually improve once the medication is stopped
- other progressive brain conditions such as progressive supranuclear palsy, multiple systems atrophy, and corticobasal degeneration
- cerebrovascular disease where a series of small strokes cause several parts of the brain to die
You can read more about parkinsonism on the Parkinson’s UK website.
New Medications For Off Time
A number of new medications approved recently are designed to reduce OFF time. These medications fall into two major categories:
- Medications that lengthen the effect of a carbidopa/levodopa dose
- Medications that are used as needed if medication effects wear off
Well give specific examples below. In general, new medications that extend the length of a carbidopa/levodopa dose are used if OFF time is somewhat predictable and occurs prior to next dose. New medications that are used as needed are most beneficial when OFF time is not predictable.
New medications that lengthen the effect of a dose of carbidopa/levodopa
- Istradefylline is an adenosine A2A receptor antagonist which was approved in the US in 2019 as an add-on therapy to levodopa for treatment of OFF time in PD. Unlike many of the other medications, it has a novel mechanism of action and is the first medication in its class to be approved for PD. It acts on the adenosine receptor, which modulates the dopaminergic system, but is not directly dopaminergic. The drug was developed in Japan and underwent clinical trials both in Japan and in the US.
- Opicapone is a catechol-O-methyltransferase inhibitor that is taken once a day. It was approved in the US in 2020 as an add-on therapy to levodopa for motor fluctuations.

Deep Brain Stimulation Surgery For Parkinson’s Disease At Ucla
If you’ve been diagnosed with Parkinson’s, your doctor will first prescribe medication. There are many drugs available that improve symptoms, but they have many side effects, including nausea, hallucinations and impulsive behavior. Some patients respond well to medications for years before seeing side effects. In these patients, the drugs may start to wear off quickly, or they may become extremely sensitive to the drugs and experience too much movement
Deep brain stimulation is a surgical option available to patients who are intolerant of medications or who experience serious side effects. This procedure involves implanting electrodes, or wires, deep inside the brain to change irregular brain activity. As a result, it improves motor function in patients with Parkinson’s disease. It is used more often to treat Parkinson’s disease than any other movement disorder.
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 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 .
Whats The Outlook For People With Vascular Parkinsonism
Vascular Parkinsonism is a chronic condition, meaning it will always be with you. But unlike PD, it doesnt necessarily have to progress or worsen over time.
Symptoms of vascular Parkinsonism can remain steady for years if an individual maintains a healthy lifestyle and works closely with a healthcare professional to manage key risk factors. Still, because the condition is caused by vascular disease, those with vascular Parkinsonism are more likely to have cardiovascular issues, such as heart disease, that can reduce life expectancy.
While the life expectancy for someone with PD may be as long as for someone without the condition, the outlook for a person with Parkinsonism in any form isnt as encouraging. Compared to the general population, those with Parkinsonism tend to have a somewhat reduced life expectancy, especially if the condition sets in prior to age 70.

How Does This Condition Affect My Body
Parkinsons disease causes a specific area of your brain, the basal ganglia, to deteriorate. As this area deteriorates, you lose the abilities those areas once controlled. Researchers have uncovered that Parkinsons disease causes a major shift in your brain chemistry.
Under normal circumstances, your brain uses chemicals known as neurotransmitters to control how your brain cells communicate with each other. When you have Parkinsons disease, you dont have enough dopamine, one of the most important neurotransmitters.
When your brain sends activation signals that tell your muscles to move, it fine-tunes your movements using cells that require dopamine. Thats why lack of dopamine causes the slowed movements and tremors symptoms of Parkinson’s disease.
As Parkinson’s disease progresses, the symptoms expand and intensify. Later stages of the disease often affect how your brain functions, causing dementia-like symptoms and depression.

Initial motor deficit is detected at 3 wk and deteriorated further 6 mo after treatment. Decrease of TH-immunoreactivity in the substantia nigra, associated with significant loss of substantia nigra neurons Persistent reduction in the levels of striatal terminal DA, its metabolites and uptake Murine inclusion bodies immunoreactive to a-synuclein and ubiquitin contain lipofuscin and lysosomal structures. Morphologically, these inclusion bodies resemble those detected in the cortex of PD. striatal levels remain low. The loss of DA neurons in the substantia nigra 6 mo after treatment is estimated to be at least 60 .

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:
Stages of Parkinsons disease
How Common Is Parkinson’s
About 1 in 500 people have Parkinsons. Most people develop it between 55 to 65 years of age.
- Parkinsons is most common in older people. About 1 in 100 people over the age of 60 are diagnosed with Parkinsons.
- Parkinsons in people younger than 60 years of age is known as early-onset Parkinsons. Of people diagnosed with Parkinsons, about 1 in 20 are younger than 40 years.
- In rare cases, Parkinsons-like symptoms can occur in children and teenagers. This is known as juvenile parkinsonism and is considered to be a separate condition to Parkinsons.
There is a very small increase in Parkinsons risk in people with family/whnau who have Parkinsons.

Diagnosis And Management Of Parkinsons Disease
There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.
No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.
People can manage their Parkinsons disease symptoms through:
- seeing a Doctor who specialises in Parkinsons
- multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
- deep brain stimulation surgery .
Medications For People With Parkinsons Disease
Symptoms of Parkinsons disease result from the progressive degeneration of nerve cells in the brain and other organs such as the gut, which produce a neurotransmitter called dopamine. This causes a deficiency in the availability of dopamine, which is necessary for smooth and controlled movements. Medication therapy focuses on maximising the availability of dopamine in the brain. Medication regimes are individually tailored to your specific need. Parkinsons medications fit into one of the following broad categories:
- levodopa dopamine replacement therapy
- dopamine agonists mimic the action of dopamine
- COMT inhibitors used along with levodopa. This medication blocks an enzyme known as COMT to prevent levodopa breaking down in the intestine, allowing more of it to reach the brain
- anticholinergics block the effect of another brain chemical to rebalance its levels with dopamine
- amantadine has anticholinergic properties and improves dopamine transmission
- MAO type B inhibitors prevent the metabolism of dopamine within the brain.
