Symptoms Related To Brain Function Are Different
There is some overlap, but in general, the overall cognitive symptoms that people experience with Parkinsons disease dementia and Alzheimers are different. Alzheimers mainly affects language and memory at the outset, whereas Parkinsons affects problem-solving, speed of thinking, memory, and mood.6
Unlike in Alzheimers disease, people with Parkinsons-related dementia often experience hallucinations, delusions, and paranoid thoughts. Both conditions can lead to depression, anxiety, and sleep disturbances.4,6
What Is Parkinson Disease
Parkinson disease is a movement disorder. It can cause the muscles to tighten and become rigid This makes it hard to walk and do other daily activities. People with Parkinsons disease also have tremors and may develop cognitive problems, including memory loss and dementia.
Parkinson disease is most common in people who are older than 50. The average age at which it occurs is 60. But some younger people may also get Parkinson disease. When it affects someone younger than age 50, it’s called early-onset Parkinson disease. You may be more likely to get early-onset Parkinson disease if someone in your family has it. The older you are, the greater your risk of developing Parkinson disease. It’s also much more common in men than in women.
Parkinson disease is a chronic and progressive disease. It doesn’t go away and continues to get worse over time.
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:

Dementia Is A Greater Risk Factor In Parkinsons Disease
Overwhelming stress, cardiovascular illness, and negative reactions to the Parkinsons disease medicine levodopa can all raise the chance of dementia. Dementia is uncommon in patients who have Parkinsons disease before the age of 50, regardless of how long they have had the disease.
It is crucial to remember that Parkinsons disease dementia can proceed at different rates in different people. While there are no treatments to slow the rate at which PDD damages brain cells, medicines can assist to alleviate symptoms. Self-help techniques can also help you live a full and meaningful life for as long as feasible.
Pdd: A Type Of Dementia Caused By Parkinsons Disease
Parkinsons disease dementia is a brain illness that affects some persons with Parkinsons disease, but not all. The diseases destruction of brain cells can result in memory loss as well as other cognitive abilities like problem-solving and thinking speed. These mental and behavioral shifts might have an impact on your daily life, independence, and relationships.
There is at least a yearand generally 10 to 15 yearsbetween the Parkinsons diagnosis and the start of dementia in people who do get dementia due to Parkinsons disease. The Alzheimers Association believes that 50 percent or more of persons with Parkinsons disease may acquire dementia at some point, while there are a number of risk factors that influence the likelihood of acquiring symptoms:
Patients with Parkinsons disease who have hallucinations, excessive daytime sleepiness, or significant motor control deficits are more likely to develop dementia.
Dementia is more likely in persons who are older when they first develop Parkinsons disease.

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.
Palliative Care In Dementia
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 .

Is Dementia A Symptom Of Both
One of the biggest similarities between PD and LBD is dementia. Some studies have found that approximately 78 percent of PD patients will eventually develop dementia.4 More specifically, almost half of Parkinsons patients will develop a certain type of dementia called Parkinsons Dementia, usually 10-15 years after their initial PD diagnosis.3 People with Parkinsons Dementia commonly experience poor memory and concentration, slowed thinking, confusion, depression, emotional changes, delusions, and visual hallucinations.
Parkinsons dementia is different than LBD, mainly in which symptoms occur first . Patients with Parkinsons Dementia will first show Parkinsons motor symptoms, followed by dementia many years after diagnosis. Conversely, LBD patients will first show dementia symptoms and may show motor symptoms later.3

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.

Building A Lewy Body Dementia Care Team
After receiving a diagnosis, a person with LBD may benefit from seeing a neurologist who specializes in dementia and/or movement disorders. Your primary doctor can work with other professionals to follow your treatment plan. Depending on an individual’s particular symptoms, physical, speech, and occupational therapists, as well as mental health and palliative care specialists, can be helpful.
Support groups are another valuable resource for people with LBD and their caregivers. Sharing experiences and tips with others in the same situation can help people find practical solutions to day-to-day challenges and get emotional and social support.
Lewy Body Dementia: A Common Yet Underdiagnosed Dementia
While its not a household word yet, Lewy body dementia is not a rare disease. It affects an estimated 1.4 million individuals and their families in the United States. Because LBD symptoms can closely resemble other more commonly known disorders like Alzheimers disease and Parkinsons, it is often underdiagnosed or misdiagnosed. In fact, many doctors or other medical professionals still are not familiar with LBD.

Lewy Body Dementia Vs Parkinsons Disease Dementia
Diagnoses of Lewy body dementia include dementia with Lewy bodies and Parkinsons disease dementia. Symptoms in both of these diagnoses can be similar.
Lewy body dementia is a progressive dementia caused by abnormal deposits of a protein called alpha-synuclein in the brain. Lewy bodies are also seen in Parkinsons disease.
The overlap in symptoms between Lewy body dementia and Parkinsons disease dementia include movement symptoms, rigid muscles, and problems with thinking and reasoning.
This seems to indicate that they could be linked to the same abnormalities, though more research is needed to confirm that.
The later stages of Parkinsons disease have more severe symptoms that may require help moving around, around-the-clock care, or a wheelchair. Quality of life can decline rapidly.
Risks of infection, incontinence, pneumonia, falls, insomnia, and choking increase.
Hospice care, memory care, home health aides, social workers, and support counselors can be a help in later stages.
Parkinsons disease itself isnt fatal, but complications can be.

Causes And Risk Factors
PD is idiopathic, meaning that a doctor does not know why a person has the condition. However, according to Johns Hopkins Medicine, early-onset Parkinsons disease has links to genetic inheritance from a parent.
Researchers have identified several risk factors that may make a person with Parkinsons disease more likely to experience dementia.
These risk factors include:
- advanced age at time of diagnosis
- experiencing excessive daytime sleepiness
- hallucinations before the onset of other dementia symptoms
- having a specific Parkinsons symptom that causes a person to have difficulty starting to take a step or to halt mid-step while walking
- a history of mild thought impairment
- more severe movement impairment symptoms than most people with Parkinsons disease
However, researchers do not know why some people with Parkinsons disease develop cognitive difficulties as well as movement problems.

Can Parkinsons Dementia Be Reversed
No specific cure has been identified for Parkinsons Disease Dementia. Rather, treatments have been aimed at reducing the symptoms of dementia and helping the patient maintain a high quality of life. Doctors treating patients of PD Dementia generally prescribe medications such as:
- Antidepressants
- Cholinesterase inhibitors
- Clonazepam and L-dopa
Serotonin reuptake inhibitors are known to reduce depression symptoms. The ones widely prescribed by doctors include:
Cholinesterase inhibitors help reduce the effects of cognitive decline in people with dementia whereas Clonazepam helps enhance sleep quality. L-dopa helps reduce movement issues caused by PD but runs the risk of making confusion and dementia symptoms worse.
Doctors treating PD Dementia patients may also prescribe antipsychotic drugs but generally do so with caution, the reason being these reduce psychotic episodes but increase Parkinsons symptoms. The use of these drugs may also cause increased confusion and change in consciousness. For the record, Pimavanserin and Nuplazid have been identified as effective antipsychotic drugs.

Coping With Dietary Problems
Many people with Parkinsons experience various eating and dietary problems, such as constipation, chewing and swallowing difficulties, and upset stomach. The following tips can help you minimize the symptoms.
If you suffer from constipation Drink lots of water and eat fiber-rich foods, including beans, brown rice, whole grains, and fruit.
If you have trouble chewing or swallowing food Cut foods into smaller portions to avoid choking and to encourage digestion, and remain upright for 30 minutes after eating.
If youre struggling with fatigueLimit the amount of sugar youre eating. Also avoid alcohol and caffeine, especially before bed, as they can reduce the quality of your sleep.
If you take levodopa Dont eat meat or other protein-rich foods for at least 30-60 minutes after taking levodopa, as protein blocks your bodys ability to absorb the medication.
If your medication gives you an upset stomach Take your medication with a full glass of water and a small non-protein based snack, such as a piece of toast or fruit.
Some Parkinsons disease medications need to be taken promptly at specified times before or after eating, so it can also help to establish a regular routine for meal and medication times.

What Is Parkinsons Disease And How Does It Affect You
Parkinsons disease is a degenerative central nervous system ailment caused by nerve cells in the brain releasing insufficient amounts of the neurotransmitter dopamine, which controls movement. It usually begins slowly, on one side of the body, as a minor tremor in one hand, for example.
Trembling may spread to both sides of the body as the condition progresses, and it may be accompanied by additional symptoms such as muscle rigidity, slowness of movement, and a loss of balance and coordination. While there is no cure for Parkinsons disease, the symptoms can be managed with drugs and other treatments.
While motor functions are disrupted in the majority of Parkinsons disease symptoms, not everyone suffers all of them, including the most prevalent ones like tremors. The rate at which the disease progresses also differs substantially from one person to the next.
Lack of energy, pain, and changes in mood and memory are all symptoms that some people experience as a result of the disease. As the disease develops, some people will develop Parkinsons disease dementia , which includes memory loss and other cognitive impairments.
A Parkinsons disease diagnosis can be incredibly upsetting for you and your family. You might be concerned about what the future holds and how you will cope. The possibility of having Parkinsons disease dementia will further heighten these fears.
What Is Parkinsons
Parkinsons disease is a condition that affects the brain and nervous system. As many as one in five hundred people in the UK are affected, with the disease causing progressive problems with stiffness, shaking and slow movement. This is because nerve cells in the brain that produce an important chemical messenger called dopamine, steadily die off, leading to symptoms getting worse and worse with time.

What Is The Self
Protein in the diet may affect the absorption of levodopa, the major medication used to treat Parkinsons disease. Fluctuations in the level of levodopa may worsen some behavioral and cognitive symptoms. A low-protein diet may reduce fluctuations in dopamine levels. In some patients with these fluctuations, dietary changes can improve symptoms. However, it is important to ensure that the person is getting adequate calories and other nutrients.
People with Parkinsons disease should remain as active as possible. Physical therapy helps the person maintain mobility.
In general, people with Parkinsons disease plus dementia should no longer drive vehicles. Movement problems may prevent quick reactions in hazardous driving situations. Certain medications, especially those given to treat symptoms of dementia, may make them less alert. However, this should be determined on an individual basis and in compliance with the laws of the state.

Symptoms And Mortality Of Parkinsons Disease With Dementia
Parkinsons disease turns into Parkinsons disease with dementia at least one year after the initial diagnosis, well after those PD symptoms above become apparent. As PD becomes PDD, the following symptoms start to appear: Anxiety, depression, and irritability Delusions Paranoia Inability to process visual information Hallucinations Memory loss
While people with Parkinsons have only slightly higher mortality rates than people without the disease, mortality rates significantly increase for people with PDD. In other words, someone with PDD is more likely to die sooner than someone who has Parkinsons without dementia. The disease is not fatalyou cannot die from Parkinsonsbut mortality rates increase because falls and accidents become more likely. Add dementia and it becomes dangerous, making caregiving, or finding the right assisted living or memory care home , more important.

Pdd Signs And Symptoms
The following are some of the most common indications and symptoms of Parkinsons disease dementia:
- Memory and attention problems
- Visual hallucinations are a common occurrence.
It is critical to have yourself or a loved one checked out if you detect any of the following signs and symptoms. But do not make hasty judgments. Anxiety, a lack of desire, and slower thinking are common cognitive impairments in people with Parkinsons disease. These signs do not always indicate dementia.
How Is Parkinson Disease Treated
Parkinson disease can’t be cured. But there are different therapies that can help control symptoms. Many of the medicines used to treat Parkinson disease help to offset the loss of the chemical dopamine in the brain. Most of these medicines help manage symptoms quite successfully.
A procedure called deep brain stimulation may also be used to treat Parkinson disease. It sends electrical impulses into the brain to help control tremors and twitching movements. Some people may need surgery to manage Parkinson disease symptoms. Surgery may involve destroying small areas of brain tissue responsible for the symptoms. However, these surgeries are rarely done since deep brain stimulation is now available.

Study Selection And Characteristics
Electronic searching retrieved 1552 records, and 14 more were identified from hand searching. Excluding duplicates and non-human studies, 1519 records underwent preliminary screening 84 were potentially relevant and were read in full. In all, 40 of these were discarded, in most cases due to the lack of relevant detail or PD cases with dementia. Ultimately, 44 articles involving 41 study groups were included . Inter-rater agreement was 96.8% at initial screening, and 93.6% at the full-text stage.
Significant predictors of dementia in Parkinsons disease by multivariable regression
One study of 104 cases used receiver operating characteristic curves to predict dementia in PD, and found that mean cortical Lewy body score alone was the best predictor 0.80, 95% CI 0.720.88). However, another study of 56 cases indicated that diagnostic accuracy was improved by the addition of indicators of amyloid- and tau pathology .
Only one study found that cognitive scores were unrelated to any measure of -synuclein, amyloid- or tau pathology, though the Lewy body score predicted the annual rate of cognitive decline. The best predictor of annual decline was a summated score incorporating both Lewy and Alzheimer pathologies of the prefrontal cortex, according to a study that used multiple backward regressions.
