Living Well With Parkinsons
While medication and DBS surgery are the most effective treatments for PD, individuals often choose to delay these treatments because of their adverse side effects. Until a therapy is developed that can halt the progression of PD, there is a significant need for strategies that provide symptom relief without causing negative side effects.
Diet, Exercise, and Stress Reduction
Findings from several studies suggest that exercise has the potential to provide relief from certain PD symptoms. Anecdotally, people with Parkinsons disease who exercise typically do better. However, many questions remain. Among them is whether exercise provides a conditioning effect by strengthening muscles and improving flexibility or whether it has a direct effect on the brain.
In an NINDS-funded trial comparing the benefits of tai chi, resistance training, and stretching, tai chi was found to reduce balance impairments in people with mild-to-moderate PD. People in the tai chi group also experienced significantly fewer falls and greater improvements in their functional capacity.

So What Do We Know So Far
Location of the substantia nigra. FrozenManCC BY-SA 4.0
The substantia nigra is an area of the mid brain located at the top of the spinal cord, which has been the focus of much work into how Parkinsons affects the brain.
There are a right and a left substantia nigra, and often one side is affected before the other. Because of this, people with Parkinsons often experience symptoms primarily on one side of their body, particularly in the early stages. Indeed, this common feature of the condition often helps to distinguish Parkinsons from other similar conditions.
When it comes to confirming a diagnosis, it is the substantia nigra where pathologists look for changes at the end of life in brain tissue that has been donated to research. And the loss of the dopamine-producing cells in this area of the brain, accompanied by the presence of clumps of alpha-synuclein protein , has been the hallmark of Parkinsons for decades.
You can read more about the alpha-synuclein protein, and how it plays a role in the spread of Parkinsons, in a previous blog post:

How Does Essential Tremor Affect My Body
Essential tremor causes parts of your body to shake when you try to use them. This is usually a problem when using your hands but can also affect your head, voice and other body parts. Essential tremor is a condition that gets worse slowly, taking years to reach levels where it starts to disrupt a persons life.
In the earlier stages, essential tremor isnt a problem. Some people may find it makes certain activities harder, but many can compensate. However, as the condition worsens, it can cause problems with fine-detail work and activities, such as handwriting, using eating utensils, sewing or tasks requiring precision.
As essential tremor worsens, this condition can have more severe effects. People who have it may not be able to feed themselves or even cook because of how severely their hands shake. Others may not be able to write, dress, bathe or otherwise take care of themselves.

Dural Lymphatic Vasculature: A New Player In The Pathophysiology Of Parkinsons Disease
Many researchers are drawn to studying the brain because theyre still making basic discoveries about how this mysterious organ works. One of those recent discoveries may be key to deciphering the causes of Parkinsons disease.
Most organs in the body have a lymphatic system to drain toxins, waste and other unwanted materials. After long believing it did not exist, researchers have realized the brain, too, has a lymphatic system to do this cleansing work.
At Toronto Western Hospital, Scientific Associate Naomi Visanji, a neuroscientist, immediately saw the implications of this discovery. Shes investigating the lymph vessels in the brain to see if they door coulddrain alpha-synuclein, a protein that accumulates in the brain cells critical to Parkinsons disease. That accumulation kills the brain cells producing dopamine, the chemical that signals other cells to initiate movement.
Because lymph vessels are involved in drainage of fluid, waste and other unwanted material, its a natural idea that the vessels might be involved in the drainage of excess toxic proteins in the brain, says Visanji.
Using imaging equipment, Visanji will compare the brains of two mouse models. One has been genetically engineered to remove its lymphatic vessels in the brain the other is a normal mouse.
The next questionrequiring a further studyis whether these vessels are damaged in people with Parkinsons disease.

What Are The Symptoms Of Essential Tremor
The key symptom of essential tremor is shaking usually your hands when youre trying to use them. That shaking can take different forms and usually happens under certain circumstances. The forms and circumstances where tremors are likely include:
- Action tremor: This is a form of essential tremor that happens during actions, such as reaching for an object.
- Postural tremor: This is shaking that happens when you hold part of your body in a specific pose, such as holding a hand outstretched and keeping it at the same height.
Essential tremor almost always affects both sides of your body but often affects one side more than the other. In addition to your hands, tremors can affect other parts of your body such as your head, voice, face and trunk.
The tremor itself isn’t dangerous, but it can cause problems with everyday activities as the condition worsens. Eventually, people with essential tremor may have trouble with activities such as eating with utensils and drinking from a glass, dressing themselves and writing.
Essential tremor gets better or worse under certain circumstances. Examples include:
| May help tremors |
|---|
| Illness. |
| Electrolyte, thyroid or blood sugar problems. |
Tremor terms
When healthcare providers diagnose essential tremor, they analyze the way the tremors happen. Two key components of tremors are their frequency and their amplitude. The following example explains these terms and what they look like in a hand tremor:

What Are The Types Of Corticobasal Degeneration
Corticobasal syndrome is a term used to specify that the symptoms, taken together, are similar to corticobasal degeneration. Many underlying neurodegenerative diseases can be caused by corticobasal syndrome, including:
- Progressive supranuclear palsy. Approximately 1 in 4 people have a type that resembles progressive supranuclear palsy. It affects balance, eye movement, speech and swallowing.
- Frontotemporal dementia. About 15% of people have frontotemporal dementia. They may struggle to organize their thoughts and behave in inappropriate, uninhibited ways.
- Dementia. An estimated 5% develop a type of dementia thats similar to Alzheimers disease. They have problems with memory and gauging spatial distances between themselves and other people or objects.
- Aphasia. Five percent have language problems or aphasia. They have trouble finding the right words to say and become unable to follow grammar rules.

How Is Corticobasal Degeneration Treated
For corticobasal degeneration, therapies focus on helping compensate for the difficulties with coordination and speech. Medication therapies may help manage muscle jerks or help improve attention or mood-related changes. Treatments for other movement disorders like Parkinsons disease arent often effective. There isnt a treatment to cure the disease.
Your healthcare provider may recommend:
- Occupational therapy to help you learn new ways to complete daily tasks and maintain independence.
- Physical therapy to help maintain mobility and ease muscle contractions.
- Speech therapy to aid communication and swallowing.
Who Does It Affect
The risk of developing Parkinsons disease naturally increases with age, and the average age at which it starts is 60 years old. Its slightly more common in men or people designated male at birth than in women or people designated female at birth .
While Parkinsons disease is usually age-related, it can happen in adults as young as 20 .

Recognising the signs
A combination of signs can help a doctor make an early diagnosis. If Parkinsons disease is diagnosed early, the chances of being able to treat and manage the condition are greater. Individual signs may not be an indication of Parkinsons disease. Some signs such as loss of smell could be caused by an infectious illness, or joint stiffness by conditions like arthritis.
Parkinsons is most commonly diagnosed with a very physical examination and assessment of a persons medical history. There are very specific markers for diagnosis which doctors use to assess for possible Parkinsons disease. These markers have a lot to do with a combination of very specific signs and symptoms and if recognised early enough, can be better managed.
1. Primary motor symptoms
2. Secondary motor symptoms
Other motor symptoms include:
Some individuals may also experience the following:
- Hunched over / stooped posture – When standing, the body may begin to slouch or lean inwards, causing a hunched over appearance.
- Impaired gross motor coordination
- Impaired fine motor dexterity and motor coordination
- Difficulties with swallowing or chewing
- Production of excess saliva and drooling
- Sexual dysfunction
3. Non-motor symptoms
Symptoms that do not involve physical movement or coordination, and often precede motor problems, can include:
Symptoms are initially mild, even if they develop suddenly, and typically affect one side of the body at first.
Who Gets Parkinsons Disease
Estimates vary, but about 1 million people are living with Parkinsons disease in the U.S. Doctors diagnose about 60,000 cases a year, most in people over age 60. Younger people can also get Parkinsons. About 5-10% of patients have young-onset Parkinsons disease, diagnosed before age 50.
About 15% of patients have Parkinsons-plus syndromes, also known as atypical Parkinsons. Medications may be less effective for these syndromes, which can lead to disability sooner.
Risk factors for Parkinsons disease include:
- Age: Risk increases with age. Average age at diagnosis is 65.
- Gender: Men are at higher risk.
- Environmental exposure: Lifetime exposure to well water, which may contain pesticide runoff, can increase risk. So can exposure to air particles containing heavy metals, such as in industrial areas.
- Family history: Having a close relative with the disease could increase your risk. Researchers have identified a dozen genes that may be linked to Parkinsons disease.
- Sleep disorder: People who act out their dreams are up to 12 times more likely to develop Parkinsons disease. Its not clear whether this condition, called REM sleep behavior disorder or RBD, is a cause or symptom of Parkinsons disease.
- Head trauma: Traumatic brain injury increases risk of Parkinsons, even years later.

What Causes Corticobasal Degeneration
Researchers currently think corticobasal degeneration is a form of frontotemporal degeneration and distinct from Alzheimers disease. The breakdown of cells here affects your brains frontal and temporal lobes.
The condition occurs when a tau, a protein normally found in brain cells, abnormally clumps together. These clumps, or neurofibrillary tangles, cause your brain cells to degenerate or die. This leads to problems with movement, speech and memory.

How Will My Doctor Test For It
There’s no one test for Parkinson’s. A lot of it’s based on your symptoms and health history, but it could take some time to figure it out. Part of the process is ruling out other conditions that look like Parkinson’s. The docotor may do a DaT scan, which looks for dopamine in the brain. This can aid in a diagnosis.
Because there is no single test, it’s very important to go to a doctor who knows a lot about it, early on. It’s easy to miss.
If you do have it, your doctor might use what’s called the Hoehn and Yahr scale to tell you what stage of the disease you’re in. It ranks how severe your symptoms are from 1 to 5, where 5 is the most serious.
The stage can help you get a better feel for where your symptoms fall and what to expect as the disease gets worse. But keep in mind, some people could take up to 20 years to move from mild to more serious symptoms. For others, the change is much faster.
How Is Periodic Limb Movement Disorder Treated
First, certain products and medications should be avoided. Caffeine often intensifies PLMD symptoms. Caffeine-containing products such as chocolate, coffee, tea, and soft drinks should be avoided. Also, many antidepressants can cause a worsening of PLMD in many patients and should be reviewed, discussed and replaced by your doctor.
Generally, there are several classes of drugs that are used to treat PLMD. These include dopamine agonist, anticonvulsant medications, benzodiazepines, and narcotics. Current treatment recommendations consider the dopamine agonist as a first line of defense. Medical treatment of PLMD often significantly reduces or eliminates the symptoms of these disorders. There is no cure for PLMD and medical treatment must be continued to provide relief.

New Ongoing And Published Research
In 2001, VA created six specialized centers to provide Veterans state-of-the-art clinical care, education, research, and advocacy for Parkinson’s disease.
Known as the Parkinson’s Disease Research, Education, and Clinical Centers , they are located in Philadelphia, Richmond, Virginia, Houston, Los Angeles, San Francisco, and the Seattle/Portland area. The centers also provide comprehensive diagnosis and treatment services for other movement disorders, including essential tremor, restless leg syndrome, dystonia, Lewy body disease, progressive supranuclear palsy, multiple system atrophy, and corticobasal degeneration.
Researchers at these sites are studying the biochemical pathways involving dopamine and testing a variety of treatment approaches for PD, including medication, surgery, and electrical stimulation. Biomedical and clinical studies on PD are ongoing at many other VA sites as well.

How Is Parkinsons Disease Diagnosed
Someone with the symptoms of Parkinsons disease may be sent to see a neurologist, a doctor who specializes in the brain, nerves, and muscles. The neurologist may do some tests, including a brain scan and blood tests. These tests will not make the diagnosis of Parkinsons disease, but the doctor will want to make sure that there is no other problem causing the symptoms. To diagnose Parkinsons disease, the doctor relies on a persons medical history, symptoms, and a physical exam.

Beyond The Substantia Nigra
In Parkinsons, other areas of the brain beyond the substantia nigra are involved as the condition progresses. Changes in higher brain areas are linked to non-motor symptoms that can affect people with Parkinsons later on in the condition, and often have a significant impact on quality of life.
For instance, symptoms that affect memory and thinking can be linked to the presence of Lewy bodies in the largest area of the brain the cerebral cortexas well as the limbic system. The limbic system is also believed to be involved in symptoms involving mood and pain, and similar changes in the inferior temporal gyrus, an area of the brain involved in processing what we see, are thought to be the reason for hallucinations.
But research into the spread of Parkinsons through these areas, and how we can stop it , is just one side of the story. There is also ongoing research into where Parkinsons starts, and the effects it is having before it reaches these areas.
The presence of non-motor symptoms many months and maybe even years before the physical symptoms, such as tremor and slowness of movement, points towards the presence of other changes in the body long before the loss of dopamine-producing cells in the substantia nigra. These early symptoms could even help researchers predict those who will go on to be diagnosed with Parkinsons, which would help in the development of new and better treatments.
How Is Parkinson’s Disease Treated
If a doctor thinks a person has Parkinson’s disease, there’s reason for hope. Medicine can be used to eliminate or improve the symptoms, like the body tremors. And some experts think that a cure may be found soon.
For now, a medicine called levodopa is often given to people who have Parkinson’s disease. Called “L-dopa,” this medicine increases the amount of dopamine in the body and has been shown to improve a person’s ability to walk and move around. Other drugs also help decrease and manage the symptoms by affecting dopamine levels. In some cases, surgery may be needed to treat it. The person would get anesthesia, a special kind of medicine to prevent pain during the operation.
