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.
Sleep Disturbances In Parkinsons Disease
In general, research seems to indicate that people with Parkinsonâs disease have more sleep disruptions than similarly aged people without the disease. The most commonly reported sleep-related problems are the inability to sleep through the night and difficulty returning to sleep after awakening, generally referred to as maintenance insomnia. Unlike many older adults, patients with Parkinsons disease often find that they have no trouble initiating sleep, but often wake up within a few hours and find sleeping through the rest of the night to be difficult. People with Parkinsonâs disease also report daytime sleepiness, nightmares, vivid dreams, nighttime vocalizations, leg movements/jerking while asleep, restless legs syndrome, inability to or difficulty turning over in bed, and awakenings to go to the bathroom.
Although all the reasons for these sleep changes are unknown, potential explanations include reactions to/side effects of medications and awakening due to symptoms such as pain, stiffness, urinary frequency, tremor, dyskinesia, depression and/or disease effects on the internal clock.

- Communicate with your care partners and let them know how they can best help you.
They Are Agitated Irritable Or Accusatory
Paranoid hallucinations, and the fears they induce, can make a person with Parkinsons related psychosis hostile. One common example: There can be delusions of sexual jealousy where they feel like their partner is having an affair, even though theyre not, says Barrett. This can be very frustrating for partners who are also caregivers.

Sleep Problems At Later Stages Of Pd
In addition to the conditions already mentioned, during the later stages of PD, you also may experience sleep problems related to higher doses of medications, such as hallucinations.
As many as 33% of Parkinsonâs patients during mid and later stages of the disorder experience hallucinations, related to medication side effects. Hallucinations tend to occur visually rather than hearing them . They are frequently associated with vivid dreams.

Hallucinations In Parkinsons Disease
Hallucinations are seeing, hearing, or feeling something that is not actually there. Most hallucinations experienced in PD are visual, although some people experience auditory, tactile , or olfactory hallucinations. Hallucinations occur when the person is awakenot sleeping or dreamingand can occur at any time of day or night. They can be frightening, for the patient experiencing them as well as their caregiver. Generally, hallucinations are repetitive and last for a short duration.1,3

Could Covid Delirium Bring On Dementia
Illustration by Fatinha Ramos
In her job as a physician at the Boston Medical Center in Massachusetts, Sondra Crosby treated some of the first people in her region to get COVID-19. So when she began feeling sick in April, Crosby wasnt surprised to learn that she, too, had been infected. At first, her symptoms felt like those of a bad cold, but by the next day, she was too sick to get out of bed. She struggled to eat and depended on her husband to bring her sports drinks and fever-reducing medicine. Then she lost track of time completely.
For five days, Crosby lay in a confused haze, unable to remember the simplest things, such as how to turn on her phone or what her address was. She began hallucinating, seeing lizards on her walls and smelling a repugnant reptilian odour. Only later did Crosby realize that she had had delirium, the formal medical term for her abrupt, severe disorientation.
I didnt really start processing it until later when I started to come out of it, she says. I didnt have the presence of mind to think that I was anything more than just sick and dehydrated.
Delirium is so common in COVID-19 that some researchers have proposed making the condition one of the diseases diagnostic criteria. The pandemic has sparked physicians interest in the condition, says Sharon Inouye, a geriatrician at the Marcus Institute for Aging and Harvard Medical School in Boston, who has studied delirium for more than 30 years.
Network Changes And Thalamic Drivers
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.

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 .

Tips For Better Sleep
The best place to start is with your doctor, who may be able to change or adjust your Parkinsonâs medications so that they interfere with sleep less. In some cases, you might be able to take a medication that helps you stay awake during the day so you sleep better at night.
If you have a sleep disorder or depression, other medications may help. Be sure to ask your doctor before taking any over-the-counter sleep medications. Many contain an antihistamine, which can actually make Parkinsonâs symptoms worse.
There are also sleep strategies you can try for yourself:
Stick to a regular sleep schedule. Getting up and going to bed at the same time every day, even on weekends, can help regulate your sleep cycle.
Avoid caffeine for at least six hours before bedtime. That means chocolate as well as coffee, tea, and sodas with caffeine.
Stay active during the day and avoid taking naps. The energy you expend during the day will leave you more tired at night. Complete your exercise regimen at least 3 hours before bedtime to optimize pre-sleep relaxation.
Get outside for some exercise every day. Morning sunshine helps set your biological clock.
Limit fluids in the evening. Avoid drinking a lot of fluid in the hours before bed to cut down on the need to urinate in the middle of the night.
Try a relaxation routine. Get in the habit of treating yourself before bed to a relaxing activity such as a hot bath or shower or a gentle massage.

What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms
Exercise: Exercise helps improve muscle strength, balance, coordination, flexibility, and tremor. It is also strongly believed to improve memory, thinking and reduce the risk of falls and decrease anxiety and depression. One study in persons with Parkinsons disease showed that 2.5 hours of exercise per week resulted in improved ability to move and a slower decline in quality of life compared to those who didnt exercise or didnt start until later in the course of their disease. Some exercises to consider include strengthening or resistance training, stretching exercises or aerobics . All types of exercise are helpful.
Eat a healthy, balanced diet: This is not only good for your general health but can ease some of the non-movement related symptoms of Parkinsons, such as constipation. Eating foods high in fiber in particular can relieve constipation. The Mediterranean diet is one example of a healthy diet.
Preventing falls and maintaining balance: Falls are a frequent complication of Parkinsons. While you can do many things to reduce your risk of falling, the two most important are: 1) to work with your doctor to ensure that your treatments whether medicines or deep brain stimulation are optimal and 2) to consult with a physical therapist who can assess your walking and balance. The physical therapist is the expert when it comes to recommending assistive devices or exercise to improve safety and preventing falls.
Common Causes Of Hallucinations
Hallucinations most often result from:
- Schizophrenia. More than 70% of people with this illness get visual hallucinations, and 60%-90% hear voices. But some may also smell and taste things that arent there.
- Parkinsons disease. Up to half of people who have this condition sometimes see things that arent there.
- Alzheimers disease. and other forms of dementia, especially Lewy body dementia. They cause changes in the brain that can bring on hallucinations. It may be more likely to happen when your disease is advanced.
- Migraines. About a third of people with this kind of headache also have an aura, a type of visual hallucination. It can look like a multicolored crescent of light.
- Brain tumor. Depending on where it is, it can cause different types of hallucinations. If its in an area that has to do with vision, you may see things that arent real. You might also see spots or shapes of light. Tumors in some parts of the brain can cause hallucinations of smell and taste.
- Charles Bonnet syndrome. This condition causes people with vision problems like macular degeneration, glaucoma, or cataracts to see things. At first, you may not realize its a hallucination, but eventually, you figure out that what youre seeing isnt real.
- Epilepsy. The seizures that go along with this disorder can make you more likely to have hallucinations. The type you get depends on which part of your brain the seizure affects.

Characteristics Of Pd Tremors
The tremors of PD characteristically occur at rest, stop with voluntary action, and recur again after you hold your new position for a few minutes. PD tremors can affect the hands, arms, face, jaw, legs, and/or feet, and are often slightly more prominent on one side than the other.
The tremor almost always begins in the hand before affecting other parts of the body, and it usually looks like you are rolling a pill between your thumb and index finger. Thats why its called a pill-rolling tremor.
A pill-rolling tremor is the most common type of PD tremor, but shaking tremorswhich may involve the hands or other areas of the bodycan also occur.

What Triggers Psychosis In Parkinsons Disease
Psychosis in Parkinsons disease is believed to be due to long term use of parkinsonian medications especially dopaminergic and anticholinergic drugs . However, significant medication exposure is no longer a pre-requisite in Parkinsons disease psychosis . The continuum hypothesis states that medication-induced psychiatric symptoms in Parkinsons disease starts with sleep disturbances accompanied by vivid dreams, and then develops into hallucinations and delusions, and ends in delirium. However this theory is now being challenged .

I am a very active person, but deep fatigue must be addressed with rest. Taking a day to rest is not in my nature. It makes me feel like a sloth. Yet, when deep fatigue hits me, the best remedy is to do just that take the day off! I limit myself to one day of physical rest, very rarely two days . I also find that the mind must rest with the body. Getting the mind to a quiet place is the practice of meditation, in whatever form suits the moment. At the height of deep fatigue, meditation can be very difficult, but not impossible. At times, it has taken me four hours to quiet my mind and body to get rejuvenating rest.
But there is a caution here: Be wary of using rest as an excuse to procrastinate. In another column, Ill address the link of scenario looping to set-shifting issues and difficulty initiating new tasks. Basically, getting off the sofa can be problematic if I stay there too long. Perhaps this seems contradictory to my history as a highly active person, but that is the nature of PDs nonmotor effects. Once off the sofa, I make myself shift into a physical task, followed by a short rest and then some type of mental task. There is always some resistance to overcome to do this to get off the sofa but the rest is absolutely necessary to stop the deep fatigue.
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.

Why Do Parkinsons Patients Sleep So Much
Parkinsonâs patients experience difficulties with their sleep due to the disease itself and the medications that treat it. This can lead to increased sleepiness during the day.
Parkinsons disease can cause problems with sleep, and the medications used to treat it can cause even more. Difficulties sleeping during the night can cause daytime sleepiness, and the medications can also cause drowsiness. This disruption to the circadian rhythms can lead to more frequent, lower quality sleep.
