What Can I Expect If A Loved One Or I Have Lewy Body Dementia
Each persons experience with Lewy body dementia is unique to them. How slowly or quickly the disease progresses is impossible to know, but may be influenced by your general health and any existing conditions you may have.
Because LBD is a progressive disease, difficulties with mind and body functions get worse over time. Currently, theres no known way to stop the progression of the disease.
However, theres always hope. Research on dementia with Lewy bodies, Alzheimers disease and Parkinsons disease with dementia are ongoing. New medications are being developed and new treatment approaches are being investigated.
Can Gene Therapy Help Prevent Dementia In Patients Having Parkinsons Disease
The efficiency of gene therapy can still be said to be in its infancy stage. Ongoing human and animal trials of gene therapy are still going on. They involve methods to insert genes in the neuronal cells in order to reduce Parkinsons disease symptoms by causing these cells to produce dopamine. Since researches are still going on, it is not very clear if such therapy actually prevent Parkinson disease and dementia associated with it till now.
Dementia Can Be Treated Through Medication But Its Progression Will Continue
Some of the problems caused by dementia are treatable, but there are no medications that slow the progression of this problem, just as there are no treatments that slow the progression of the rest of the Parkinsons Disease syndrome. We often use the same medications that are used in Alzheimers disease to improve concentration and memory, although only one, rivastigmine, has been approved by the Food and Drug Administration for dementia in PD. Most experts believe that each of the Alzheimer drugs are about as useful in dementia in Parkinsons Disease as they are in Alzheimers, which, unfortunately, is not great. As with all medications used in PD, whether for slowness, stiffness, tremor, depression or sleep disorders, if the medication is not helpful, one should either try a higher dose or stop it. Since the drugs used to treat dementia take several weeks to work, and the dose often requires increases, the family needs to allow a reasonable time period, usually around two months, to decide if it is helpful or not. Obviously this needs to be discussed with the prescribing doctor.
There is a lot of research being done to better understand and better treat dementia in PD.

Is Parkinson’s A Form Of Dementia
Parkinson’s disease is not a form of dementia and it often develops completely independently of dementia. However, you may have heard the term “Parkinson’s dementia” – this refers to a form of dementia that only affects people with Parkinson’s. The important distinction is that not everyone with Parkinson’s develops this.
What is the link between Parkinson’s disease and dementia?
Signs And Symptoms Of Pdd
Common signs and symptoms of Parkinsons disease dementia include:
- Poor memory and concentration
- Visual hallucinations
If youve noticed some of the above signs and symptoms in yourself or a loved one, its important to get them checked out. But dont jump to conclusions. People with Parkinsons often experience cognitive changes such as anxiety, lack of motivation, and slowed thinking. These symptoms do not automatically mean dementia.

What Causes Parkinson Disease
Parkinson disease arises from decreased dopamine production in the brain. The absence of dopamine makes it hard for the brain to coordinate muscle movements. Low dopamine also contributes to mood and cognitive problems later in the course of the disease. Experts don’t know what triggers the development of Parkinson disease most of the time. Early onset Parkinson disease is often inherited and is the result of certain gene defects.
What Is Parkinsons Disease
Parkinsons disease is a condition in which a part of the brain called the substantia nigra loses nerve cells. This loss of nerve cells results in a reduction of a substance called dopamine which is important for the regulation of movement of the body. As the dopamine levels decrease the persons movements become slower. Most people with a diagnosis of Parkinsons do not go on to develop dementia although about a third will, usually in the later stages. This is known as Parkinsons disease with dementia and may also be referred to as Lewy body dementia.
It is estimated that Parkinsons disease affects about 1 in 500 people and it is currently thought that it may be due to a combination of genetic and environmental causes. About one fifth of people diagnosed with Parkinsons disease are under 40 years old but it is more common in the over 50s.

What Is Aggressive Parkinsons Disease
As written above, Parkinsons dementia aggression is that form of Parkinsons which makes the patient exhibit aggressive behavior. They vent out their aggression either verbally or physically, in the various forms that have been written above. Besides verbal and physical outbursts, PD Dementia patients are also prone to hallucinating caused by the medication administered. Hallucinations in PD Dementia patients primarily occur because of the effects of dopaminergic agents for motor symptoms.
Loss of dopamine neurons in the ventral tegmental area is one of the likeliest of all neuropathological causes as changes in serotonin and norepinephrine systems are not. For the uninitiated, the ventral tegmental area is the origin of the mesolimbic dopaminergic projection. Plenty of studies have gone into analyzing the cause behind the aggression in PD Dementia patients. Depression in PD Dementia patients has been identified due to changes in the medial frontal cortex and the anterior cingulate. Akinetic-rigid variants have been found in patients showing signs of major depression.
Parkinson’s Dementia And Dementia With Lewy Bodies
“Both of these types of dementia involve abnormal protein deposits called Lewy bodies forming in brain cells. Because they are so similar, you may hear both of them being called Lewy body dementia.”
According to Fletcher, the symptoms of Parkinson’s dementia and dementia with Lewy bodies can be very similar. These include both motor and cognitive symptoms:
Physical symptoms could include:
“However, the order in which movement and mental symptoms appear is different,” adds Fletcher. “If there have been motor symptoms for at least one year before dementia symptoms occur, specialists will often give a diagnosis of Parkinson’s dementia.
“If dementia symptoms occur before or at the same time as motor symptoms, specialists will usually give a diagnosis of dementia with Lewy bodies.”

How Is Parkinsons Disease Dementia Diagnosed
No single test can diagnose Parkinsons disease dementia. Instead, doctors rely on a series or combination of tests and indicators.
Your neurologist will likely diagnose you with Parkinsons and then track your progression. They may monitor you for signs of dementia. As you get older, your risk for Parkinsons dementia increases.
Your doctor is more likely to conduct regular testing to monitor your cognitive functions, memory recall, and mental health.
Caring For Someone With Parkinsons
Caring for someone with Parkinsons disease or dementia can be a rewarding as well as challenging experience. It will likely involve adapting to new challenges over time as the disease progresses or new symptoms emerge.
Become informed. Learn as much as you can about Parkinsons disease and Parkinsons disease dementia and how it is likely to affect your loved one specifically, given their health history, age, and lifestyle.
Communicate openly and provide reassurance, especially in the early stages following diagnosis, that Parkinsons disease is only slowly progressive in most patients and that your loved one can still live a full life.
Modify tasks to allow for greater independence. Allow your loved one to do things for themselves even if it takes longer. If necessary, break tasks that involve fine motor skills into easier steps and focus on success, not failure.
Help your loved one find alternative means of transport if they have to give up driving. That may involve researching public transportation, ride sharing, or community shuttle services.
Exercise together. Exercising is vital for the health and state of mindof both of you. Take a class together or simply enjoy a walk outside.
Look after yourself. Take regular breaks to avoid caregiver burnout, maintain social ties, and seek out opportunities to relax and have fun. Talking to others in similar situations can be very helpful.

Do You Die From Pd Dementia
People with Parkinsons-related dementia often want to know how the disease can impact their lifespan. While people with Parkinsons can expect a similar lifespan to the general population, studies show both Parkinsons disease dementia and Lewy body dementia can shorten lifespan, generally due to medical complications from the disease, rather than the disease itself.
Parkinson’s Disease And Dementia
Parkinson’s disease and dementia are both progressive conditions that get worse over time. They are also both far more common among the older population:
What’s more, a person with Parkinson’s disease may have a higher chance of developing dementia at some stage. It’s thought that this happens in roughly half of all people with Parkinson’s. Results of studies that tracked patients over 10 years and eight years respectively suggest that dementia is diagnosed in between 30% and almost 80% of people with Parkinson’s.
Yet, it’s important to understand Parkinson’s and dementia as two different degenerative conditions:
- They don’t have the same primary causes or primary symptoms.
- It’s common to develop one without the other.

Are Support Groups Available For Patients With Parkinsons Disease
Support groups and counseling facilities are available for patients who suffer from Parkinsons disease as well as their caregivers.
Emotional Release: The support groups allow the patient to express his feelings and try reducing the mental burden in some way.
Counseling: These support groups help in counseling the patients in order to help them cope better with their problems.
Motivation for Caregivers: The support groups also aim at helping the caregivers of such patients by providing them with strength that they may need.
Different Ways of Support: The support groups and counseling team meet the patients in person or may converse on telephone or over the internet. Various organizations may provide details of such groups.
Theres No Cure For The Diseases But Some Therapies May Help
Certain drugs, like cholinesterase inhibitors and antipsychotic medications, are prescribed as treatment for people with Parkinsons and dementia. And lifestyle changesfrom improved diet, sleep, exercise and socializinghave been shown to have beneficial effects on patients with these diseases.
Oguh noted she hopes that improved treatments that will help some of the emotional and behavioral problems in these patients will be on the horizon soon.
Im hoping that with the new advances in medication, well be able to control better, Oguh said. I believe there will be better medication to improve cognition in patients, and that that will be seen in the next five to 10 years.

Pd Dementia And Safety Concerns
Safety issues should be considered and monitored from the time of diagnosis. As PDD progresses, ensure that your loved one is not left alone and try to:
- Evaluate driving privileges before safety is a concern. Your doctor can make a driving evaluation referral.
- Work out legal and financial issues and safeguard finances. People with dementia are at greater risk of falling victim to scams and fraud.
- Minimize prescription risks. Confirm with the doctor the medication names and doses of the person with PD. If the person is in dementias early stages and capable, fill up their weekly pill box together and monitor use.
- Look into medical alert systems. These systems can be critical in the event of a fall or if your loved one wanders outside of the home. Many types of systems are available, from bracelets and pendants to smartwatches with fall detection and one-button connections to 911.
- Evaluate gun safety. If your loved one owns a firearm or has one in the home, consider bringing it up with their doctor and taking additional safety precautions.
Dementia And Cognitive Change
Cognition or cognitive function is a term used to describe the thought processes of your brain.
Cognition includes judgement, reasoning, problem-solving and memory. It is thought that the majority of people with Parkinsons experience some changes to their cognition. This is known as cognitive impairment. In people living with Parkinsons the level of cognitive impairment is mild in most cases.

Tip : Make Other Healthy Lifestyle Choices
In addition to regular exercise, eating a healthy diet, and interacting with others, there are plenty of other steps you can take to manage Parkinsons symptoms and lower your risk for dementia.
1. Seek mental stimulation. By continuing to learn new things and challenge your brain, you can strengthen your cognitive skills and stay mentally sharp. Another great way to improve brain function is to learn a new skill, whether its a musical instrument, a foreign language, a new computer program, or a new game or sport. Classes at community centers or colleges can help you to tackle new subjects.
2. Improve the quality of your sleep.Good sleep is important for flushing out toxins and protecting your brain. Most adults need 7 to 9 hours of quality sleep. Establish a regular sleep schedule, create relaxing bedtime rituals such as taking a bath or doing some light stretches, and turn off all screens at least one hour before sleep.
3. Manage stress. Unchecked stress takes a heavy toll on the brain, shrinking a key memory area, hampering nerve cell growth, and can make many Parkinsons symptoms worse. Overwhelming stress may even increase your risk for developing dementia. As well as connecting face-to-face with others, exercise and relaxation techniques such as meditation or deep breathing can help you lower your stress levels.

Typical Timescale For Pdd
According to the Parkinsons Foundation, PDD is typically diagnosed when a person living with Parkinsons disease experiences cognitive decline after a year or more of motor symptoms. But in most cases, people experience many years of tremors, slowness of movement, and muscle cramps before showing signs of significant cognitive decline. The Weill Institute for Neurosciences estimates the average time from onset of movement problems to developing dementia is 10 years. An estimated 50% to 80% of people with Parkinsons will eventually experience Parkinsons disease dementia, says the Alzheimers Association.

S For Caring For A Person With Parkinsons Dementia
Parkinsons disease is known for its associated motor symptoms, such as tremor and slowed movement. People can be surprised to learn that cognitive changes are among common PD non-motor symptoms. Significant cognitive impairment can impact care partners, too. Education and healthy coping strategies ensure everyones best care.
The following article is based on a Parkinsons Foundation Expert Briefings webinar exploring care partner strategies to identify and help people with PD dementia, hosted by Joseph Quinn, MD, a neurologist at Parkinsons Foundation Center of Excellence Oregon Health & Science University and the Portland VA Medical Center. Dr. Quinn, the Parkinsons Center director for both institutions, focuses his research on cognitive decline prevention and dementia treatment.
What is PD Dementia?
Mild cognitive impairment is very common with Parkinsons disease. It can impact memory and thinking but doesnt always affect daily activities. Dementia, however, is when cognitive changes impact daily living. Dementia may or may not occur in people with PD. According to recent research, 30 percent of people with Parkinsons do not develop dementia as part of the disease progression.
The different types of dementia include:
Parkinsons Disease Dementia and Lewy Body Dementia Family Checklist
Why Is Proper Follow
A person with Parkinsons disease is supposed to go for regular checkups to his health care professional for the following reasons-
Treatment Progress: The check-ups help the health care professionals to check if the treatment procedure is working or not and also provides an insight about the necessary adjustments to be made.
Detecting New Issues- Regular follow-ups help in detection of new problems with cognition, behavior or mood which might need special treatment.
Planning the Care- The follow-ups provide a platform for caregivers to discuss the problems with respect to the patients care.
Presence of Dementia: It can also be known if the patient is susceptible to dementia with the help of regular checkups.
Dementia: It may happen so that the person with Parkinsons disease developing dementia may not be able to take care of himself or take decisions about his healthcare. Thus, caregivers should be extra careful and follow the regular follow-ups with the doctor.

Medications To Help Treat Parkinsons Disease Psychosis
Your doctor might consider prescribing an antipsychotic drug if reducing your PD medication doesnt help manage this side effect.
Antipsychotic drugs should be used with extreme caution in people with PD. They may cause serious side effects and can even make hallucinations and delusions worse.
Common antipsychotic drugs like olanzapine might improve hallucinations, but they often result in worsening PD motor symptoms.
Clozapine and quetiapine are two other antipsychotic drugs that doctors often prescribe at low doses to treat PD psychosis. However, there are concerns about their safety and effectiveness.
In 2016, the approved the first medication specifically for use in PD psychosis: pimavanserin .
In clinical studies , pimavanserin was shown to decrease the frequency and severity of hallucinations and delusions without worsening the primary motor symptoms of PD.
The medication shouldnt be used in people with dementia-related psychosis due to an increased risk of death.
Psychosis symptoms caused by delirium may improve once the underlying condition is treated.
There are several reasons someone with PD might experience delusions or hallucinations.
