Apda Centers For Advanced Research: Spotlight On Mayo Clinic Jacksonville Florida
Your support helps APDA fund eight Centers for Advanced Research across the United States, where some of the best scientists in the field are conducting cutting-edge investigations that are helping us understand what causes PD and how best to treat it, and ultimately getting us closer to a cure.
One of these centers is at the Mayo Clinic in Jacksonville, Florida, where Dr. Dennis Dickson, MD, directs a busy center. Thanks to you, they are able to:
- Identify novel gene mutations that contribute to Parkinsonism
- Conduct a range of clinical trials looking at everything from gait in advanced PD to Lewy bodies of the gut
- Maintain a very active Deep Brain Stimulus program with 75-100 procedures performed per year
- See approximately 1,500 patients each year
Tremors Are Just One Of Many Symptoms That May Indicate Parkinson’s Disease
In addition to tremors, there are several other symptoms to look out for if you suspect PD. According to the Mayo Clinic, many patients experience slowed movement, rigid muscles, impaired balance, poor posture, and a decreased ability to perform unconscious movements, like swinging your arms while you walk. Additionally, PD patients often notice changes to their speech, including speaking more softly, speaking in monotone, developing a slur, or hesitating before speaking. Finally, some people with Parkinson’s find that their handwriting changesâit may become increasingly difficult to write, and your handwriting may become smaller over time.

Mayo Clinic Talks: Exercise Is First
Daily exercise has so many health and emotional benefits it can help decrease your blood pressure, promote cardiovascular wellbeing, alleviate stress, and assist with weight loss and blood sugar control. Parkinsons disease is a condition that affects the central nervous system, and in particular the brain, that can lead to shakiness, poor balance, and frequent falls. Joining us in this episode is Edward Laskowski, M.D., a professor of physical medicine and rehabilitation and sports medicine specialist at Mayo Clinics Rochester Campus, to discuss why exercise is first-line treatment for your Parkinsons patients.

What Are The Early Warning Signs Of Parkinson’s Disease
Parkinsons warning signs can be motor symptoms like slow movements, tremors or stiffness. However, they can also be non-motor symptoms. Many of the possible non-motor symptoms can appear years or even decades ahead of motor symptoms. However, non-motor symptoms can also be vague, making it difficult to connect them to Parkinson’s disease.
Non-motor symptoms that might be early warning signs include:
- Sleep problems such as periodic limb movement disorder , rapid eye movement behavior disorder and restless legs syndrome.
Though There’s No Cure For Pd Early Diagnosis Is Still Essential
While unfortunately there is currently no cure for Parkinson’s that reverses the course of the disease, the Parkinson’s Foundation points out that there are many ways to treat symptoms. These may include a combination of medication, lifestyle interventions, and in some cases neurosurgery, which can be effective in reducing tremors. Reaching a diagnosis early and finding the right treatment plan for your symptoms can have a significant impact on quality of life. If you believe you may be experiencing symptoms of Parkinson’s disease, contact a healthcare provider as soon as possible.

How Soon After Treatment Will I Feel Better And How Long Will It Take To Recover
The time it takes to recover and see the effects of Parkinson’s disease treatments depends strongly on the type of treatments, the severity of the condition and other factors. Your healthcare provider is the best person to offer more information about what you can expect from treatment. The information they give you can consider any unique factors that might affect what you experience.
How Is It Treated And Is There A Cure
For now, Parkinsons disease is not curable, but there are multiple ways to manage its symptoms. The treatments can also vary from person to person, depending on their specific symptoms and how well certain treatments work. Medications are the primary way to treat this condition.
A secondary treatment option is a surgery to implant a device that will deliver a mild electrical current to part of your brain . There are also some experimental options, such as stem cell-based treatments, but their availability often varies, and many aren’t an option for people with Parkinsons disease.

Is Early Diagnosis Possible
Experts are becoming more aware of symptoms of Parkinsons that precede physical manifestations. Clues to the disease that sometimes show up before motor symptoms and before a formal diagnosis are called prodromal symptoms. These include the loss of sense of smell, a sleep disturbance called REM behavior disorder, ongoing constipation thats not otherwise explained and mood disorders, such as anxiety and depression.
Research into these and other early symptoms holds promise for even more sensitive testing and diagnosis.
For example, biomarker research is trying to answer the question of who gets Parkinsons disease. Researchers hope that once doctors can predict that a person with very early symptoms will eventually get Parkinsons disease, those patients can be appropriately treated. At the very least, these advances could greatly delay progression.
How Do I Take Care Of Myself
If you have Parkinsons disease, the best thing you can do is follow the guidance of your healthcare provider on how to take care of yourself.
- Take your medication as prescribed. Taking your medications can make a huge difference in the symptoms of Parkinson’s disease. You should take your medications as prescribed and talk to your provider if you notice side effects or start to feel like your medications aren’t as effective.
- See your provider as recommended. Your healthcare provider will set up a schedule for you to see them. These visits are especially important to help with managing your conditions and finding the right medications and dosages.
- Dont ignore or avoid symptoms. Parkinsons disease can cause a wide range of symptoms, many of which are treatable by treating the condition or the symptoms themselves. Treatment can make a major difference in keeping symptoms from having worse effects.

What Tests Will Be Done To Diagnose This Condition
When healthcare providers suspect Parkinsons disease or need to rule out other conditions, various imaging and diagnostic tests are possible. These include:
- Blood tests .
- Positron emission tomography scan.
New lab tests are possible
Researchers have found possible ways to test for possible indicators or Parkinsons disease. Both of these new tests involve the alpha-synuclein protein but test for it in new, unusual ways. While these tests cant tell you what conditions you have because of misfolded alpha-synuclein proteins, that information can still help your provider make a diagnosis.
The two tests use the following methods.
- Spinal tap. One of these tests looks for misfolded alpha-synuclein proteins in cerebrospinal fluid, which is the fluid that surrounds your brain and spinal cord. This test involves a spinal tap , where a healthcare provider inserts a needle into your spinal canal to collect some cerebrospinal fluid for testing.
- Skin biopsy. Another possible test involves a biopsy of surface nerve tissue. A biopsy includes collecting a small sample of your skin, including the nerves in the skin. The samples come from a spot on your back and two spots on your leg. Analyzing the samples can help determine if your alpha-synuclein has a certain kind of malfunction that could increase the risk of developing Parkinsons disease.
Mayo Clinic Develops Potential New Therapy To Stop The Progression Of Parkinson’s Disease
JACKSONVILLE, Fla., and ROCHESTER, Minn., Nov. 17 /PRNewswire-USNewswire/ — Mayo Clinic researchers have developed a method to reduce the production of alpha-synuclein in the brain. Alpha-synuclein is a protein that is believed to be central to the cause of Parkinson’s disease . All patients with Parkinson’s disease have abnormal accumulations of alpha-synuclein protein in the brain.
Additional audio and video resources, including excerpts from an interview with Dr. Maraganore describing the research, are available on the Mayo Clinic News Blog .
The new method involves the delivery of RNA interference compounds directly to selected areas of the brain via injection. The RNA interference compounds silence the gene that produces alpha-synuclein, according to the Mayo researchers. The study was published this month in Molecular Neurodegeneration.
Parkinson’s disease is a progressive disorder that affects nerve cells in the part of the brain that controls muscle movement. Symptoms include tremor, slowed movement and rigid muscles. At least 1 million people in the U.S. are believed to have Parkinson’s disease, and 2 percent of the population can expect to develop the disease during their lifetime.
“While our research has not yet been tested on humans, we expect that these findings will lead to an effective treatment for slowing or even halting the progression of Parkinson’s disease,” says Demetrius Maraganore, M.D. , a Mayo Clinic neurologist.

What Causes The Condition
Although there are several recognized risk factors for Parkinsons disease, such as exposure to pesticides, for now, the only confirmed causes of Parkinsons disease are genetic. When Parkinsons disease isnt genetic, experts classify it as idiopathic . That means they dont know exactly why it happens.
Many conditions look like Parkinson’s disease but are instead parkinsonism from a specific cause like some psychiatric medications.
Familial Parkinsons disease
Parkinsons disease can have a familial cause, which means you can inherit it from one or both of your parents. However, this only makes up about 10% of all cases.
Experts have linked at least seven different genes to Parkinson’s disease. They’ve linked three of those to early-onset of the condition . Some genetic mutations also cause unique, distinguishing features.
Idiopathic Parkinsons disease
Experts believe idiopathic Parkinsons disease happens because of problems with how your body uses a protein called -synuclein . Proteins are chemical molecules that have a very specific shape. When some proteins dont have the correct shape a problem known as protein misfolding your body cant use them and can’t break them down.
With nowhere to go, the proteins build up in various places or in certain cells . The buildup of these Lewy bodies causes toxic effects and cell damage.
The possible causes are:
What Can I Expect If I Have This Condition
Parkinsons disease is a degenerative condition, meaning the effects on your brain get worse over time. However, this condition usually takes time to get worse. Most people have a normal life span with this condition.
You’ll need little to no help in the earlier stages and can keep living independently. As the effects worsen, youll need medication to limit how the symptoms affect you. Most medications, especially levodopa, are moderately or even very effective once your provider finds the minimum dose you need to treat your symptoms.
Most of the effects and symptoms are manageable with treatment, but the treatments become less effective and more complicated over time. Living independently will also become more and more difficult as the disease worsens.
How long does Parkinsons disease last?
Parkinsons disease isnt curable, which means its a permanent, life-long condition.
Whats the outlook for Parkinsons disease?
Parkinson’s disease isn’t fatal, but the symptoms and effects are often contributing factors to death. The average life expectancy for Parkinson’s disease in 1967 was a little under 10 years. Since then, the average life expectancy has increased by about 55%, rising to more than 14.5 years. That, combined with the fact that Parkinson’s diagnosis is much more likely after age 60, means this condition doesn’t often affect your life expectancy by more than a few years .

What Are The Symptoms
The best-known symptoms of Parkinson’s disease involve loss of muscle control. However, experts now know that muscle control-related issues aren’t the only possible symptoms of Parkinson’s disease.
Motor symptoms which means movement-related symptoms of Parkinsons disease include the following:
Additional motor symptoms can include:
- Blinking less often than usual. This is also a symptom of reduced control of facial muscles.
- Cramped or small handwriting. Known as micrographia, this happens because of muscle control problems.
- Drooling. Another symptom that happens because of loss of facial muscle control.
- Mask-like facial expression. Known as hypomimia, this means facial expressions change very little or not at all.
- Trouble swallowing . This happens with reduced throat muscle control. It increases the risk of problems like pneumonia or choking.
- Unusually soft speaking voice . This happens because of reduced muscle control in the throat and chest.
Several symptoms are possible that aren’t connected to movement and muscle control. In years past, experts believed non-motor symptoms were risk factors for this disease when seen before motor symptoms. However, theres a growing amount of evidence that these symptoms can appear in the earliest stages of the disease. That means these symptoms might be warning signs that start years or even decades before motor symptoms.
Non-motor symptoms include:
Stages of Parkinsons disease
Can Parkinson’s Disease Be Cured
No, Parkinson’s disease is not curable. However, it is treatable, and many treatments are highly effective. It might also be possible to delay the progress and more severe symptoms of the disease.
A note from Cleveland Clinic
Parkinson’s disease is a very common condition, and it is more likely to happen to people as they get older. While Parkinson’s isn’t curable, there are many different ways to treat this condition. They include several different classes of medications, surgery to implant brain-stimulation devices and more. Thanks to advances in treatment and care, many can live for years or even decades with this condition and can adapt to or receive treatment for the effects and symptoms.

Growth Of Parkinson Disease Knowledge: Rodolfo Savica Md Phd
The consultant in the Department of Neurology at Mayo Clinic discussed the advancements of Parkinson disease knowledge and treatment over the past 2 decades.
“The mistake weve been doing over the years, even in the medication trial and neuroprotective trials, is that we lump everything together. We know that Parkinson disease is not 1 disease. If we are able to identify differences in groups, its possible that agents that failed in the past, may be used now.
Although symptoms of possible Parkinson disease can be found in very early documents, the first clear medical description was written in 1817 by James Parkinson. The first treatments for PD were based on empirical observation, and anticholinergic drugs were used as early as the nineteenth century. The discovery of dopaminergic deficits in PD and the synthetic pathway of dopamine led to the first human trials of levodopa, a drug that is still considered the standard treatment today.
Since then, the knowledge of PD has grown, but unfortunately there is still no cure. Other medications doctors have prescribed for patients include carbidopa-levodopa infusion, dopamine agonists, MAO B inhibitors, Amantadine, and anticholinergics. According to Rodolfo Savica, MD, PhD, knowledge of the disease has increased the most in the sense that clinicians understand the final pathology of the accumulation of alpha synuclein Lewy bodies.
You May Also Experience Tremors In Other Parts Of The Body
Tremors are one of the most common PD symptoms, and besides the hands and fingers, “it can also appear in other parts of the body, including the lower lip, jaw or leg,” according to the Parkinson’s Foundation. These tremors can impair motor coordination and make everyday activities, such as dressing, shaving, and eating, a challenge for PD patients. However, there’s one silver lining for those who suffer from the symptom: “People with resting tremor usually have a more slowly progressing course of illness than people without tremor,” the Parkinson’s Foundation explains.ae0fcc31ae342fd3a1346ebb1f342fcb
Parkinson’s tremors typically affect just one side of the body, especially early in the course of the disease. However, over time, both sides may become affected.

What Doctors Look For When Diagnosing Parkinsons
Certain physical signs and symptoms noticed by the patient or his or her loved ones are usually what prompt a person to see the doctor. These are the symptoms most often noticed by patients or their families:
Shaking or tremor: Called resting tremor, a trembling of a hand or foot that happens when the patient is at rest and typically stops when he or she is active or moving
Bradykinesia: Slowness of movement in the limbs, face, walking or overall body
Rigidity: Stiffness in the arms, legs or trunk
Posture instability: Trouble with balance and possible falls
Once the patient is at the doctors office, the physician:
Takes a medical history and does a physical examination.
Asks about current and past medications. Some medications may cause symptoms that mimic Parkinsons disease.
Performs a neurological examination, testing agility, muscle tone, gait and balance.
