Changes In Cognition And Parkinsons Disease
Some people with Parkinsons may experience changes in their cognitive function, including problems with memory, attention, and the ability to plan and accomplish tasks. Stress, depression, and some medications may also contribute to these changes in cognition.
Over time, as the disease progresses, some people may develop dementia and be diagnosed with Parkinsons dementia, a type of Lewy body dementia. People with Parkinsons dementia may have severe memory and thinking problems that affect daily living.
Talk with your doctor if you or a loved one is diagnosed with Parkinsons disease and is experiencing problems with thinking or memory.
Medicines For Parkinsons Disease
Medicines can help treat the symptoms of Parkinsons by:
- Increasing the level of dopamine in the brain
- Having an effect on other brain chemicals, such as neurotransmitters, which transfer information between brain cells
- Helping control non-movement symptoms
The main therapy for Parkinsons is levodopa. Nerve cells use levodopa to make dopamine to replenish the brains dwindling supply. Usually, people take levodopa along with another medication called carbidopa. Carbidopa prevents or reduces some of the side effects of levodopa therapy such as nausea, vomiting, low blood pressure, and restlessness and reduces the amount of levodopa needed to improve symptoms.
People living with Parkinsons disease should never stop taking levodopa without telling their doctor. Suddenly stopping the drug may have serious side effects, like being unable to move or having difficulty breathing.
The doctor may prescribe other medicines to treat Parkinsons symptoms, including:
- Dopamine agonists to stimulate the production of dopamine in the brain
- Enzyme inhibitors to increase the amount of dopamine by slowing down the enzymes that break down dopamine in the brain
- Amantadine to help reduce involuntary movements
- Anticholinergic drugs to reduce tremors and muscle rigidity
Brain Training App Useful In Early Parkinsons Cases: Pilot Study

Diagnosis Of Parkinsons Disease
There are currently no blood or laboratory tests to diagnose non-genetic cases of Parkinsons. Doctors usually diagnose the disease by taking a persons medical history and performing a neurological examination. If symptoms improve after starting to take medication, its another indicator that the person has Parkinsons.
A number of disorders can cause symptoms similar to those of Parkinsons disease. People with Parkinsons-like symptoms that result from other causes, such as multiple system atrophy and dementia with Lewy bodies, are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinsons, certain medical tests, as well as response to drug treatment, may help to better evaluate the cause. Many other diseases have similar features but require different treatments, so it is important to get an accurate diagnosis as soon as possible.
Supplements For Parkinsons Disease Management
Many people with Parkinsons take supplements as part of their health routines. In a study of supplement habits in people with PD, the following supplements appear to be associated with a decreased rate of progression of PD symptoms.
CoQ10 is an important antioxidant that helps our cells make energy. Because mitochondrial dysfunction and impaired cellular energy metabolism are implicated in the development of Parkinsons disease, it makes sense to ensure that you areat the very leastnot deficient. One of the ways to do this is to supplement regularly with an over-the-counter CoQ10 supplement. In animal studies, CoQ10 supplementation has even been shown to halt or reverse the progression of Parkinsonian symptoms.
5MTHF stands for 5-methyl-tetrahydrafolate. Its a methylated form of folate thats thought to be more bioavailable than folic acid. Many people with PD take this as a part of the protocol recommended at the beginning of this article to maximize the effectiveness of some Parkinsons medications.
Turmeric, resveratrol, and quercetin are thought to protect cell membrane health mostly via their antioxidant capabilities. Antioxidants quench free radicals that would normally damage the fatty lining of every single cell in our bodies. By doing this, they protect cell membrane health and preserve the ability of our cells to manufacture energy and signal to each other appropriately.

What Causes The Disease
The precise cause of PD is unknown, although some cases of PD are hereditary and can be traced to specific genetic mutations. Most cases are sporadicthat is, the disease does not typically run in families. It is thought that PD likely results from a combination of genetics and exposure to one or more unknown environmental factors that trigger the disease.
The protein alpha-synuclein. The affected brain cells of people with PD contain Lewy bodiesdeposits of the protein alpha-synuclein. Researchers do not yet know why Lewy bodies form or what role they play in the disease. Some research suggests that the cells protein disposal system may fail in people with PD, causing proteins to build up to harmful levels and trigger cell death. Additional studies have found evidence that clumps of protein that develop inside brain cells of people with PD may contribute to the death of neurons.
Genetics. Several genetic mutations are associated with PD, including the alpha-synuclein gene, and many more genes have been tentatively linked to the disorder. The same genes and proteins that are altered in inherited cases may also be altered in sporadic cases by environmental toxins or other factors.
Environment. Exposure to certain toxins has caused parkinsonian symptoms in rare circumstances . Other still-unidentified environmental factors may also cause PD in genetically susceptible individuals.
Parkinsons Disease Diagnosis And Prognosis
A Parkinsons disease diagnosis cannot be determined by a single test but is rather assigned based on a patients medical history, symptoms, and a series of neurological and physical exams. Each patients Parkinsons disease prognosis is different, as the disease is unique to each person. While all patients will experience some degree of motor dysfunction, the severity and course that the disease takes may differ from person to person.

A New Era For Parkinsons Disease Treatment
March 2, 2022 | By
A non-invasive ultrasound treatment for Parkinsons disease that was tested in a pivotal trial led by University of Maryland School of Medicine researchers is now broadly available at the University of Maryland Medical Center .
Howard Eisenberg, MD, Dheeraj Gandhi, MD, MBBS, Paul Fishman, MD, PhD, Bert W. OMalley, MD.
The device, called Exablate Neuro, was approved in November by the U.S. Food and Drug Administration to treat advanced Parkinsons disease on one side of the brain. The approval was based on findings from the UMSOM clinical trial and effectively expands access to focused ultrasound beyond clinical trial participation.
Rapid Reversal of Symptoms
Focused ultrasound is an incisionless procedure, performed without the need for anesthesia or an in-patient stay in the hospital. Patients, who are fully alert, lie in a magnetic resonance imaging scanner, wearing a transducer helmet. Ultrasonic energy is targeted through the skull to the globus pallidus, a structure deep in the brain that helps control regular voluntary movement. MRI images provide doctors with a real-time temperature map of the area being treated. During the procedure, the patient is awake and providing feedback, which allows doctors to monitor the immediate effects of the tissue ablation and make adjustments as needed.

A New Era for Parkinsons Disease Treatment
What Is Parkinson’s Disease
Parkinsons disease is movement disorder of the nervous system that worsens over time. As nerve cells in parts of the brain weaken or are damaged or die, people may begin to notice problems with movement, tremor, stiffness in the limbs or the trunk of the body, or impaired balance. As these symptoms become more obvious, people may have difficulty walking, talking, or completing other simple tasks. Not everyone with one or more of these symptoms has PD, as the symptoms appear in other diseases as well.
No cure for PD exists today, but research is ongoing and medications or surgery can often provide substantial improvement with motor symptoms.

Parkinsons Disease: Causes Symptoms And Treatments
Parkinsons disease is a brain disorder that causes unintended or uncontrollable movements, such as shaking, stiffness, and difficulty with balance and coordination.
Symptoms usually begin gradually and worsen over time. As the disease progresses, people may have difficulty walking and talking. They may also have mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue.
While virtually anyone could be at risk for developing Parkinsons, some research studies suggest this disease affects more men than women. Its unclear why, but studies are underway to understand factors that may increase a persons risk. One clear risk is age: Although most people with Parkinsons first develop the disease after age 60, about 5% to 10% experience onset before the age of 50. Early-onset forms of Parkinsons are often, but not always, inherited, and some forms have been linked to specific gene mutations.
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 .

What Will A Cure For Parkinson’s Look Like
Parkinson’s varies so much from person to person. There are over 40 symptoms of Parkinsons. Tremor. Pain. Hallucinations. Everyones experience is different.
Because of this, there may not be a single ‘cure’.
Instead, we may need a range of different therapies to meet the needs of the individual and their specific form of the condition.
This mix may include treatments, therapies and strategies that can:
- slow or stop the progression of the condition
- replace or repair lost or damaged brain cells
- control and manage particular symptoms
- diagnose Parkinson’s at the earliest possible stage.
And this could involve medical treatments, such as drugs and surgical approaches, as well as lifestyle changes, for example to diet and exercise.
What We Know So Far
- We’ve uncovered clues to the causes and genetic involvement in Parkinson’s.
- We’re figuring out the chain of events that leads to the damage and loss of brain cells.
- We’re working to advance new treatments and therapies.
- We’re exploring repurposing drugs to help manage some of the more distressing symptoms, like hallucinations and falls.
- And we know that, although people with Parkinson’s share symptoms, each person’s experience of the condition and response to treatment is different.
Now, the science is ready for us to develop the new treatments and cure that people with Parkinson’s so desperately need.
Research takes time but if you have Parkinsons, you need better treatments now. Thats why weve launched the Parkinson’s Virtual Biotech to speed up the most promising potential treatments. The more we can invest, the sooner we’ll get there.

Exploring Seven Recently Approved Parkinsons Treatments
Remarkably, in the last five years, seven new medications have been approved for the treatment of the motor symptoms of Parkinsons disease , with two approved in 2020. Thats exciting progress! And while it is great to have so many choices, the various options can be confusing so today I will describe these new medications and their uses.
Key Programs And Resources
The Parkinsons Disease Biomarkers Programs , a major NINDS initiative, is aimed at discovering ways to identify individuals at risk for developing PD and Lewy Body Dementia and to track the progression of the disease. It funds research and collects human biological samples and clinical data to identify biomarkers that will speed the development of novel therapeutics for PD. Goals are improving clinical trials and earlier diagnosis and treatment. Projects are actively recruiting volunteers at sites across the U.S. NINDS also collaborates with the Michael J. Fox Foundation for Parkinsons Research on BioFIND, a project collecting biological samples and clinical data from healthy volunteers and those with PD. For more information about the PDBP and how you can get involved, please visit the PDBP website.
The NINDS Morris K. Udall Centers of Excellence for Parkinsons Disease Research program supports research centers across the country that work collaboratively to study PD disease mechanisms, the genetic contributions to PD, and potential therapeutic targets and treatment strategies.
The NINDS Intramural Research Program conducts clinical studies to better understand PD mechanisms and develop novel and improve treatments.
The NINDS Biospecimens Repositories store and distribute DNA, cells, blood samples, cerebrospinal fluid, and autopsy tissue to PD researchers around the world.

Scientists Uncover New Targets For Treating Parkinson’s Disease
Scientists at La Jolla Institute for Immunology have found that people with Parkinson’s disease have a clear “genetic signature” of the disease in their memory T cells. The scientists hope that targeting these genes may open the door to new Parkinson’s treatments and diagnostics.
“Parkinson’s disease is not usually seen as an autoimmune disease,” says LJI Research Assistant Professor Cecilia Lindestam Arlehamn, Ph.D. “But all of our work points toward T cells having a role in the disease.”
“Now that we can see what these T cells are doing, we think intervening with antibody therapies could have an impact on the disease progression, especially early on, ” adds LJI Professor Alessandro Sette, Dr.Biol.Sci., who led the work with Lindestam Arlehamn.
This study was published recently in the journal npj Parkinson’s Disease.
A shifting view of Parkinson’s
Parkinson’s progresses as dopamine-producing neurons in the brain die. Unfortunately, scientists have been unable to pinpoint what causes this cell deaththough they do have a clue: The doomed neurons contain clumps of a damaged protein called alpha-synuclein.
LJI research suggests these clumps may be the kiss of death for dopamine-producing neurons. Sette and Lindestam Arlehamn recently showed that people with Parkinson’s have T cells that target alpha-synuclein early on in Parkinson’s disease.

The path to new Parkinson’s therapies
Barrie Man Raises $15000 For Parkinson’s Disease
Barries Nathan Langille has volunteered at the annual Parkinson Canada SuperWalk since he was 38.
Eight years later, he is in better control of his Young Onset Parkinsons disease and he has also raised $15,000 to help others make the journey.
Parkinson’s is a lifelong, incurable brain disease that occurs when brain cells involved in mobility and coordination are dying. As a progressive disease, symptoms slowly worsen, and new ones, such as anxiety, depression and sleep concerns, develop over time.
This year, Langille hopes to raise his largest annual contribution through his fundraising efforts, that have included bottle drives and garage sales.
His family will be walking as the Nathans Cure Chasers team at the SuperWalk event in Barrie on September 10 at Sunnidale Park.
Currently, more than 100,000 Canadians live with Parkinsons, and that number is expected to increase in the coming years.
Parkinson Canada SuperWalk is the largest annual fundraiser for Parkinson Canada, and to-date, the event has raised over $40 million for research, support tools, and advocacy for people living with Parkinsons.
Important Points About The New Medications
With multiple new medications available for the treatment of PD, there is more hope than ever that Parkinsons symptoms can be successfully managed for many years. A few things to consider:
- For people whose symptoms are difficult to control, these new treatments are welcome additions to what was previously available and many people with PD have been using these new medications with significant benefit.
- On the other hand, many of the newly-approved medications have the same mechanisms of action as older medications so they are not breaking new ground in treating symptoms.
- In addition, for some people, the effect on symptoms may be mild or not substantial.
These caveats may mean that your physician has not suggested a medication change for you. It is also important to note that despite all the new medications, carbidopa/levodopa remains the most potent medication to treat the motor symptoms of PD.
If your doctor does choose to try one of the new options, there may be multiple paths that your doctor can take when contemplating a medication adjustment. Often trial and error is the only way to determine the best medication regimen for you, so you may need to practice some patience as you work together with your doctor to determine what works or doesnt work.
