Do You Get Dementia With Parkinson’s Disease

What Are The Surgical Treatments For Parkinsons Disease

Murat Emre, MDS 2019 Dementia in Parkinson’s disease (PDD)

Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.

How Do I Prevent Falls From Common Hazards

  • Floors: Remove all loose wires, cords, and throw rugs. Minimize clutter. Make sure rugs are anchored and smooth. Keep furniture in its usual place.
  • Bathroom: Install grab bars and non-skid tape in the tub or shower. Use non-skid bath mats on the floor or install wall-to-wall carpeting.
  • Lighting: Make sure halls, stairways, and entrances are well-lit. Install a night light in your bathroom or hallway and staircase. Turn lights on if you get up in the middle of the night. Make sure lamps or light switches are within reach of the bed if you have to get up during the night.
  • Kitchen: Install non-skid rubber mats near the sink and stove. Clean spills immediately.
  • Stairs: Make sure treads, rails, and rugs are secure. Install a rail on both sides of the stairs. If stairs are a threat, it might be helpful to arrange most of your activities on the lower level to reduce the number of times you must climb the stairs.
  • Entrances and doorways: Install metal handles on the walls adjacent to the doorknobs of all doors to make it more secure as you travel through the doorway.

Tip : Whatand Howyou Eat Can Make A Difference

Theres no specific Parkinsons disease diet, but by adjusting your eating habits, you can help protect your brain. Diets that are good for your heart tend to also be good for brain health. Eating habits such as those promoted in the Mediterranean diet can help reduce inflammation, protect neurons, and promote better communication between brain cells.

Primarily, its important to eat plenty of fruit and vegetables, cut down on sugary foods and refined carbs, reduce fried and processed foods, and boost your intake of healthy fats and home-cooked meals. High protein meals may also help to benefit your brain chemistry.

Managing The Effects Of Parkinsons Disease

Currently there is no cure for Parkinsons disease but UK and international research is ongoing.

With Parkinsons disease the interventions are focused on support, management of the changes, working with the person and their family to ensure they can live as well as possible with the condition. The physical effects of Parkinsons disease can be managed by:

  • adapting the home environment so any trip hazards are removed and risks minimised
  • a referral to Speech and Language Therapy if there are speech or swallowing problems
  • a referral to a physiotherapist if there are movement issues
  • a referral to an occupational therapist for aids and devices that may help around the house

If the person with Parkinsons has significant communication or cognitive issues they can be reduced by:

  • reviewing the medication given for Parkinsons as this may be worsening the cognitive symptoms
  • speaking slowly and clearly if understanding and thought processes are slowed
  • reducing distractions
  • giving time for communication it may take longer to respond
  • asking questions to narrow down the answer, give choices or use yes/no cards or picture cards the person may have word finding difficulties as well as needing longer to respond
  • using a mobile phone, tablet or electronic communication aid
  • avoid unfamiliar or noisy places as they can cause distress
  • providing a routine and activities that the person enjoys and feels comfortable with

Palliative Care In Dementia

A novel tool to help gain deeper insight into Parkinsons ...

The first evaluated palliative care program specific to dementia was described in 1986 . The volume of research has grown exponential after 2000 . There are few randomized controlled trials, and therefore, there is still little evidence on effectiveness . However, many western countries have funded observational studies resulting in numerous publications describing patient, family and professional caregiver needs .

Research specific to dementia is important because the course of the disease is highly variable and uncertain. Because of the progressive dementia, patients themselves often cannot remain involved in decision making. Also, health services and changes such as transfer to a hospice, do not necessarily represent optimal care for people with dementia . Palliative care in dementia needed a clear conceptualization, and the European Association for Palliative Care along with experts agreed to a distinct concept in terms of eleven domains, different from usual palliative care .

What Are The Symptoms Of Parkinson’s Disease Dementia

Cognitive impairment in Parkinson’s disease may range from a single isolated symptom to severe dementia.

  • The appearance of a single cognitive symptom does not mean that dementia will develop.
  • Cognitive symptoms in Parkinson’s disease usually appear years after physical symptoms are noted.
  • Cognitive symptoms early in the disease suggest dementia with Parkinsonian features, a somewhat different condition.

Cognitive symptoms in Parkinson’s disease include the following:

  • Loss of decision-making ability
  • Loss of short- and long-term memory
  • Difficulty putting a sequence of events in the correct order
  • Problems using complex language and comprehending others’ complex language

Persons with Parkinson’s disease, with or without dementia, may often respond slowly to questions and requests. They may become dependent, fearful, indecisive, and passive. As the disease progresses, many people with Parkinson’s disease may become increasingly dependent on spouses or caregivers.

Major mental disorders are common in Parkinson’s disease. Two or more of these may appear together in the same person.

The combination of depression, dementia, and Parkinson’s disease usually means a faster cognitive decline and a more severe disability. Hallucinations, delusions, agitation, and manic states can occur as adverse effects of drug treatment of Parkinson’s disease, this might complicate the diagnosis of Parkinson’s dementia.

How Is Age Related To Pdd

Both PD and PDD are more common with increasing age. Most people with PD start having movement symptoms between ages 50 and 85, although some people have shown signs earlier. Up to 80% of people with PD eventually develop dementia. The average time from onset of movement problems to the development of dementia is about 10 years.

What Are The Symptoms Of Parkinsons Disease

Symptoms of Parkinsons disease and the rate of decline vary widely from person to person. The most common symptoms include:

Other symptoms include:

  • Speech/vocal changes: Speech may be quick, become slurred or be soft in tone. You may hesitate before speaking. The pitch of your voice may become unchanged .
  • Handwriting changes: You handwriting may become smaller and more difficult to read.
  • Depression and anxiety.
  • Sleeping disturbances including disrupted sleep, acting out your dreams, and restless leg syndrome.
  • Pain, lack of interest , fatigue, change in weight, vision changes.
  • Low blood pressure.

How Is Parkinson Disease Diagnosed

What is Parkinson’s Disease?

Parkinson disease can be hard to diagnose. No single test can identify it. Parkinson can be easily mistaken for another health condition. A healthcare provider will usually take a medical history, including a family history to find out if anyone else in your family has Parkinson’s disease. He or she will also do a neurological exam. Sometimes, an MRI or CT scan, or some other imaging scan of the brain can identify other problems or rule out other diseases.

Treating Movement Symptoms In Lewy Body Dementia

LBD-related movement symptoms may be treated with medications used for Parkinson’s disease, called carbidopa-levodopa. These drugs can help make it easier to walk, get out of bed, and move around. However, they cannot stop or reverse the disease itself. Side effects of this medication can include hallucinations and other psychiatric or behavioral problems. Because of this risk, physicians may recommend not treating mild movement symptoms with medication. Other Parkinson’s medications are less commonly used in people with LBD due to a higher frequency of side effects.

People with LBD may benefit from physical therapy and exercise. Talk with your doctor about what physical activities are best.

Is Parkinsons Disease Inherited

Scientists have discovered gene mutations that are associated with Parkinsons disease.

There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.

Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.

Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.

How Is Parkinsons Disease Treated

There is no cure for Parkinsons disease. However, medications and other treatments can help relieve some of your symptoms. Exercise can help your Parkinsons symptoms significantly. In addition, physical therapy, occupational therapy and speech-language therapy can help with walking and balance problems, eating and swallowing challenges and speech problems. Surgery is an option for some patients.

Alzheimers Vs Parkinson’s Disease Dementia

Everything You Need to Know About Parkinsons Disease ...

The dementia of Parkinsons disease has some similarities to the dementia of Alzheimers disease. And there are some differences, too. Alzheimers disease causes dementia slowly over time, while the dementia of Parkinsons disease often develops more quickly and dramatically.

The symptoms of Parkinsons dementia can come and go from day to day, while the symptoms of Alzheimers dementia will not go away.

Lewy Body Dementia Research

Many avenues of research are being explored to improve our understanding of LBD. Some researchers are working to identify the specific differences in the brain between the two types of LBD. Others are looking at the disease’s underlying biology, genetics, and environmental risk factors. Still other scientists are trying to identify biomarkers , improve screening tests to aid diagnosis, and research new treatments.

Scientists hope that new knowledge about LBD will one day lead to more effective treatments and even ways to cure and prevent the disorder. Until then, researchers need volunteers with and without LBD for clinical studies.

NIH and other groups help people learn about clinical trials and studies and find research opportunities near them. Visit the following websites for details:

Causes Of Parkinson’s Disease

Parkinson’s disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain.

Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinson’s disease.

Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.

Coping With Alzheimers And Parkinsons Disease

Living with both Alzheimers disease and Parkinsons disease is extremely challenging. The dementia of Alzheimers combined with the movement effects of Parkinsons can make self-care especially difficult.

Rivastigmine is the only medication that is specifically approved for the treatment of Parkinsons dementia. Additionally, you may need medication for the motor symptoms of Parkinsons disease and medication to help with other symptoms, such as dry skin.

Behaviors Seen In Parkinsons Disease Dementia

Parkinsons Disease Dementia

As dementia progresses, managing disorientation, confusion, agitation, and impulsivity can be a key component of care.

Some patients experience hallucinations or delusions as a complication of Parkinsons disease. These may be frightening and debilitating. Approximately 50 percent of those with the disease may experience them.

The best thing to do when giving care to someone experiencing hallucinations or delusions from Parkinsons disease dementia is to keep them calm and reduce their stress.

Take note of their symptoms and what they were doing before they exhibited signs of hallucinating and then let their doctor know.

This element of the disease can be particularly challenging for caregivers. Patients may become unable to care for themselves or be left alone.

Some ways to make caregiving easier include:

  • sticking to a normal routine whenever possible
  • being extra comforting after any medical procedures
  • limiting distractions
  • using curtains, nightlights, and clocks to help stick to a regular sleep schedule
  • remembering that the behaviors are a factor of the disease and not the person

Managing Sleep Disorders In Lewy Body Dementia

Sleep problems may increase confusion and behavioral problems in people with LBD and add to a caregiver’s burden. A physician can order a sleep study to identify any underlying sleep disorders such as sleep apnea, restless leg syndrome, and REM sleep behavior disorder.

REM sleep behavior disorder, a common LBD symptom, involves acting out one’s dreams, leading to lost sleep and even injuries to individuals and their sleep partners. Clonazepam, a drug used to control seizures and relieve panic attacks, is often effective for the disorder at very low dosages. However, it can have side effects such as dizziness, unsteadiness, and problems with thinking. Melatonin, a naturally occurring hormone used to treat insomnia, may also offer some benefit when taken alone or with clonazepam.

Excessive daytime sleepiness is also common in LBD. If it is severe, a sleep specialist may prescribe a stimulant to help the person stay awake during the day.

Some people with LBD have difficulty falling asleep. If trouble sleeping at night persists, a physician may recommend a prescription medication. It is important to note that treating insomnia and other sleep problems in people with LBD has not been extensively studied, and that treatments may worsen daytime sleepiness and should be used with caution. Sleep problems can also be addressed by avoiding lengthy naps, increasing daytime exercise, and avoiding caffeine, alcohol, and chocolate late in the day.

Difference Between Parkinsons Disease Dementia And Dementia With Lewy Bodies

Technically, the difference between these two conditions lies in how quickly the cognitive difficulties and hallucinations develop in relation to the movement issues. In DLB, the cognitive difficulties and hallucinations develop much sooner in the disease course than in PDD, sometimes even prior to the movement difficulties. Because of the similarities between PD, PDD, and DLB, current thinking in the medical community is that they should be viewed as related diseases which fall along a continuum of Lewy body disorders.

Rem Sleep Behavior Disorder Risk Factors

Risk factors associated with an increased likelihood of developing REM sleep behavior disorder include:

  • Being a male over the age of 50. Women, on the other hand, are seeing more diagnosis of RBD when they are under the age of 50
  • Having a neurological disorder like Parkinsons disease or Lewy body dementia
  • Having a chronic sleep disorder
  • Taking certain medications like antidepressants
  • Withdrawal from drugs or alcohol

What Are The Parkinson’s Disease Dementia Criteria

Nomenclature of Lewy body diseases. Parkinsons disease ...

Many people with Parkinson’s disease experience cognitive changes , but not all of them develop full-blown dementia. So at what point does Parkinson’s disease cause dementia?

On average, Parkinson’s disease dementia happens about 10 years after a person first starts having movement problems.

“It happens many, many years after someone has developed Parkinson’s,”Lynda Nwabuobi, MD, assistant professor of clinical neurology at Weill Cornell Parkinson’s Disease and Movement Disorders Institute, tells Health. “It can be around 10 to 15 years.”

In fact, if someone shows signs of dementia early on in their Parkinson’s diagnosis , it could be that they were misdiagnosed out of the gate. “They might have dementia with Lewy bodies,” Dr. Nwabuobi explains.

Timing is the main factor in Lewy body dementia versus Parkinson’s disease dementia. While the two can look very similar, the dementia symptoms occur before motor symptoms in Lewy body dementia, and in Parkinson’s disease the reverse is true.

“If you look at the brain, it’s difficult to distinguish them,” Dr. Litvan says. “But clinically, they are different.”

Parkinsons Disease Lewy Body Dementia And Rem Sleep Behavior Disorder Related

Written byMohan GarikiparithiPublished onOctober 21, 2015

Recent research has found that Parkinsons disease, Lewy body dementia and REM sleep behavior disorder are all related. When we are asleep our body goes through different sleep phases, the deepest of which is known as rapid eye movement, or REM. During normal REM our body becomes temporarily paralyzed, and this is where we beginning dreaming. People with REM sleep behavior disorder do not become paralyzed and instead act out their dreams. This can be quite dangerous, not only for the individual, but for others around them as well.

Benjamin L. Walter, M.D., director of the Parkinsons and Movement Disorders Center at University Hospitals Case Medical Center, said to Neurology Advisor, Normally, during REM sleep, reduced serotonergic activity in the brain leads to atonia or loss of muscle tone through action in a network involving brainstem nuclei including the locus subcoeruleus and magnocellularis nucleus. In RBD, this mechanism is dysfunctional, possibly due to pathology in this circuit, and there is not loss of tone during REM sleep.

It has been found that RBD and neurological disorders are related. In fact, up to 60 percent of Parkinsons disease patients suffer from RBD and between 80 to 100 percent of Lewy body dementia patients suffer from the sleep disorder as well.
