What Are The Parkinson’s Disease Dementia Criteria
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.”
If You Develop A Tremor
Urgent medical care isn’t needed if you have had a tremorâshaking or tremblingâfor some time. But you should discuss the tremor at your next doctor’s appointment.
If a tremor is affecting your daily activities or if it is a new symptom, see your doctor sooner.
A written description will help your doctor make a correct diagnosis. In writing your description, consider the following questions:
- Did the tremor start suddenly or gradually?
- What makes it worse or better?
- What parts of your body are affected?
- Have there been any recent changes in the medicines you are taking or how much you are taking?
Who Was James Parkinson
Born in London in 1755, James Parkinson was a polymath whose interests included palaeontology, geology and politics. Under the pseudonym Old Hubert he was a leading campaigner for social reform and was an advocate for the underprivileged and universal suffrage . In 1784, he was approved as a surgeon-apothecary by the City of London Corporation.
Parkinson, a social reformer and a critic of Pitts government, joined the secret political reformist group the London Corresponding Society . In 1794, five members of the LCS were implicated in a sham conspiracy to assassinate King George III with a pop-gun, a form of poisoned dart . Parkinson was called as a witness for the defence. The so-called conspirators were eventually freed. Disillusioned by this experience, Parkinson effectively retired from his political life and focused his energies on medicine, publishing several medical papers. The most famous of these was the Essay on the Shaking Palsy published in 1817 .

Q: How Does The Delta Variant Affect Someone With Pd
A: We do not have any specific data yet on how the Delta variant affects people with PD.
The COVID-19 virus, like all viruses, is able to mutate and create variants of itself. Many variants of COVID-19 have been identified around the world. Only a few of these variants have been of concern to public health however, because they have a characteristic that makes the virus either more easily transmissible or more likely to cause significant disease. The Delta variant is currently the variant of concern and has been shown to be more easily transmitted from person to person than prior variants of COVID.
The vaccines approved in the US do offer protection against the Delta variant, but not to the extent that was seen in the original trials. That means that fully vaccinated people are more likely to get infected with the Delta variant of COVID-19 than other variants. However, the major goal of the vaccines is to prevent severe illness, hospitalization, and death from COVID-19 and all the approved vaccines are approximately 90% effective in preventing these consequences of infection. Therefore, vaccination remains extremely valuable.
What Is The Outlook For Persons With Parkinsons Disease
Although there is no cure or absolute evidence of ways to prevent Parkinsons disease, scientists are working hard to learn more about the disease and find innovative ways to better manage it, prevent it from progressing and ultimately curing it.
Currently, you and your healthcare teams efforts are focused on medical management of your symptoms along with general health and lifestyle improvement recommendations . By identifying individual symptoms and adjusting the course of action based on changes in symptoms, most people with Parkinsons disease can live fulfilling lives.
The future is hopeful. Some of the research underway includes:
- Using stem cells to produce new neurons, which would produce dopamine.
- Producing a dopamine-producing enzyme that is delivered to a gene in the brain that controls movement.
- Using a naturally occurring human protein glial cell-line derived neurotrophic factor, GDNF to protect dopamine-releasing nerve cells.
Many other investigations are underway too. Much has been learned, much progress has been made and additional discoveries are likely to come.

Q: What Happens If I Get A Cough From Covid
A: You are correct that it is important to pay attention to possible medication interactions. Cough and cold medications containing dextromethorphan, pseudoephedrine, phenylephrine, and ephedrine need to be avoided only if you are on a monoamine oxidase inhibitor such as rasagiline, selegiline or safinamide. Be sure to check the product ingredients before purchasing, and if you are unsure ask your doctor or pharmacist to clarify which brands/medications should be avoided. If you are on an MAOI, any other cold medication without these ingredients is safe for you to take. If you are not taking an MAOI, any cold medication is suitable for you.
Here is the list of medications to avoid in PD.
What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.

Establishing Pd Research Priorities
The NINDS-organized Parkinsons Disease 2014: Advancing Research, Improving Lives conference brought together researchers, clinicians, patients, caregivers, and nonprofit organizations to develop 31 prioritized recommendations for research on PD. These recommendations are being implemented through investigator-initiated grants and several NINDS programs. NINDS and the NIHs National Institute of Environmental Health Sciences held the Parkinsons Disease: Understanding the Environment and Gene Connection workshop to identify priorities for advancing research on environmental contributors to PD.
Research recommendations for Lewy Body Dementia, including Parkinsons disease dementia, were updated during the NIH Alzheimers Disease-Related Dementias Summit 2019 .
Q: What Side Effects Can I Expect From The Covid
A: While there have been some varied reactions, the COVID-19 vaccines are approved by the FDA and considered safe. Some people may simply experience a mildly sore arm and that is it . There are some who may have a more noticeable reaction and feel chills, body aches, headaches and/or fatigue for 1-2 days, but these generally clear up quickly. There have also been some anecdotal reports of PD symptoms temporarily worsening after COVID-19 vaccination.
Weighing the risks of someone with PD getting COVID-19, as well as the significant downsides of all the pandemic-related restrictions on social and physical activities to someone with PD vs. the potential for side effects from the vaccine, I would favor getting the vaccine. As always, discuss all your medical concerns with your neurologist and primary care physician.

What Causes Parkinson’s Disease
Parkinson’s disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine. When the neurons die or become impaired, they produce less dopamine, which causes the movement problems of Parkinson’s. Scientists still do not know what causes cells that produce dopamine to die.
People with Parkinson’s also lose the nerve endings that produce norepinephrine, the main chemical messenger of the sympathetic nervous system, which controls many functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain some of the non-movement features of Parkinson’s, such as fatigue, irregular blood pressure, decreased movement of food through the digestive tract, and sudden drop in blood pressure when a person stands up from a sitting or lying-down position.
Many brain cells of people with Parkinson’s contain Lewy bodies, unusual clumps of the protein alpha-synuclein. Scientists are trying to better understand the normal and abnormal functions of alpha-synuclein and its relationship to genetic mutations that impact Parkinsons disease and Lewy body dementia.
Michael Richard Clifford: Parkinson’s In Space
Michael Richard “Rich” Clifford began his career as a NASA astronaut in 1990. He’s since made three space flights, accumulating 665 hours orbiting Earth. Though diagnosed with Parkinson’s disease in 1994, he continued to fly. Clifford was 42 and in apparent good health when he discovered his Parkinson’s disease, signaled at first by difficulty moving his right arm and hand correctly. In 2012, the American Academy of Neurology gave him the Public Leadership in Neurology Award for increasing awareness of Parkinson’s disease and for encouraging people living with Parkinson’s to continue to pursue their dreams.
Everyone with PD handles it differently, said Clifford in an interview with the Michael J. Fox Foundation. Dont let it get in the way of living. Life is too good. Remember, keep going the skys the limit.

The Next Generation Of Trials
Studer was part of the initial studies involving fetal tissue in the 1980s and 1990s, and knew from the start that the work was more of a proof of principle than a solution for people with Parkinsons. For me it was clear that a fetal transplant isnt a long-term solution because of ethical, legal and practical issues. Because this procedure requires 4 to 12 fetuses per patient, there was no way they could treat thousands, let alone tens of thousands, of people that way. Instead, Studer turned to stem cells.
Immunosuppression is a particularly important element of BlueRocks approach, because it relies on a single cell line that cannot be adjusted to more closely resemble the recipients own tissues. A group led by stem-cell scientist and neurosurgeon Jun Takahashi at Kyoto University in Japan is attempting to provoke a lesser immune response by pairing transplant recipients with cells that are less likely to be rejected. The researchers are using cell-surface proteins, called major histocompatibility complexes , that are recognized by the adaptive immune system and can have varying levels of compatibility from one person to another. Rather than using frozen cell lines, Takahashi and his colleagues are creating a fresh batch of MHC-matched cells for each transplant.

Q: Once I Am Vaccinated Can I Go Back To Doing Things As I Was Doing Them Before The Pandemic Does The Emergence Of The Delta Variant Change Anything
A: The CDC continually updates its guidelines in response to evolving public health conditions.
- Fully vaccinated people can participate in many of the activities that they did before the pandemic for some of these activities, they may choose to wear a mask.
- To reduce the risk of becoming infected with the Delta variant and potentially spreading it to others, everyone, including those who are fully vaccinated, should wear a mask in public indoor settings if they are in an area of substantial or high transmission. The CDC constantly updates the map of US counties for which this applies. You will need to refer to your local public health authorities to determine whether your area is one with substantial or high transmission
- Fully vaccinated people might choose to mask regardless of the level of transmission in their area, particularly if they or someone in their household is immunocompromised or at increased risk for severe disease, or if someone in their household is unvaccinated. People who are at increased risk for severe disease include older adults and those who have certain medical conditions, such as diabetes, overweight or obesity, and heart conditions.
How Will Parkinson’s Disease Affect Your Life
Finding out that you have a long-term, progressive disease can lead to a wide range of feelings. You may feel angry, afraid, sad, or worried about what lies ahead. It may help to keep a few things in mind:
- Usually this disease progresses slowly. Some people live for many years with only minor symptoms.
- Many people are able to keep working for years. As the disease gets worse, you may need to change how you work.
- It is important to take an active role in your health care. Find a doctor you trust and can work with.
- Depression is common in people who have Parkinson’s. If you feel very sad or hopeless, talk to your doctor or see a counsellor.
- It can make a big difference to know that you’re not alone. Ask your doctor about Parkinson’s support groups, or look for online groups or message boards.
- Parkinson’s affects more than just the person who has it. It also affects your loved ones. Be sure to include them in your decisions.

Janet Reno: Public Service With Parkinson’s
The first woman to serve as U.S. attorney general, from 1993 to 2001, Janet Reno was diagnosed with Parkinson’s disease in 1995, just two years after she was nominated to the cabinet position. She was 55 at the time. “Well, my hand was shaking this summer, and I thought it would go away. I thought it was maybe you all picking on me. But it didn’t go away, and so I went and had it checked out,”Reno said during a press conference at the time.
Reno took medication to bring her symptoms under control, and although her Parkinson’s advanced, she was able to guest star as herself in a 2013 episode of The Simpsons, presiding in a trial in which Bart Simpson was the defendant.
Reno died in November 2016 at age 78.
Do Symptoms Get Worse
PD does not affect everyone the same way. The rate of progression and the particular symptoms differ among individuals.
PD symptoms typically begin on one side of the body. However, the disease eventually affects both sides, although symptoms are often less severe on one side than on the other.
Early symptoms of PD may be subtle and occur gradually. Affected people may feel mild tremors or have difficulty getting out of a chair. Activities may take longer to complete than in the past. Muscles stiffen and movement may be slower. The persons face may lack expression and animation . People may notice that they speak too softly or with hesitation, or that their handwriting is slow and looks cramped or small. This very early period may last a long time before the more classical and obvious motor symptoms appear.
As the disease progresses, symptoms may begin to interfere with daily activities. Affected individuals may not be able to hold utensils steady or they may find that the shaking makes reading a newspaper difficult.
People with PD often develop a so-called parkinsonian gait that includes a tendency to lean forward, taking small quick steps as if hurrying , and reduced swinging in one or both arms. They may have trouble initiating movement , and they may stop suddenly as they walk .

Does Parkinson’s Disease Cause Dementia
The cells in the brain affected in PD are not in the ‘thinking’ parts of the brain and dementia is not a typical early feature of PD. However, if you have PD you have an increased risk of developing dementia. About half of people with PD develop dementia at some stage. If dementia occurs, it tends to develop in older people with PD . Early dementia in younger people with PD virtually never develops. It is thought that PD alone does not cause dementia however, other age-related factors in addition to PD may increase the risk of dementia developing.
Q: Are There Any Studies Of The Effects Of The Covid
A: Currently, there is no data that the COVID-19 vaccine has any long-term negative effects on anyone, including those with PD. Some people with PD have reported a worsening of PD symptoms in the short term after vaccination, which then resolve. The Center for Disease Control instituted a vaccine safety monitoring system, called v-safe, which captures side effects of the vaccine. If you have side effects from the vaccine and have PD, you can alert the CDC using this system. This will be an invaluable tool for scientists to discover trends in vaccine side effect profiles.
