I Have Pd And Several Symptoms Should I Get A Datscan
Likely no. There is no need for DaTscan when your history and exam suggest Parkinsons disease and you meet the diagnostic criteria. Occasionally, if signs and symptoms are mild or you dont meet the diagnostic criteria, your doctor will refer you for a DaT scan. Keep in mind that ultimately the diagnosis is based on your history and physical exam. The DaT scan is most commonly used to complete the picture and is not a test for a diagnosis.
Response To Parkinsons Drugs
After examining you, and depending on the severity of your symptoms, your specialist may suggest you take medication for Parkinsons. If your symptoms improve after taking Parkinsons medication for a few weeks or months, your specialist may confirm a Parkinsons diagnosis. However, some people with other forms of parkinsonism will also respond well to these drugs.
Your specialist may suggest you have a scan to help make a diagnosis. However, scans alone cant make a definite diagnosis of Parkinsons, so they are not commonly used.
How Does This Condition Affect My Body
Parkinsons disease causes a specific area of your brain, the basal ganglia, to deteriorate. As this area deteriorates, you lose the abilities those areas once controlled. Researchers have uncovered that Parkinsons disease causes a major shift in your brain chemistry.
Under normal circumstances, your brain uses chemicals known as neurotransmitters to control how your brain cells communicate with each other. When you have Parkinsons disease, you dont have enough dopamine, one of the most important neurotransmitters.
When your brain sends activation signals that tell your muscles to move, it fine-tunes your movements using cells that require dopamine. Thats why lack of dopamine causes the slowed movements and tremors symptoms of Parkinson’s disease.
As Parkinson’s disease progresses, the symptoms expand and intensify. Later stages of the disease often affect how your brain functions, causing dementia-like symptoms and depression.

How It All Fits Together
Diagnosing Parkinsons disease can be tricky. The process relies heavily on your doctors judgment. In addition, the causes and risk factors of Parkinsons are not entirely clear yet, which contributes to the difficulty in diagnosing this condition.
However, there have been efforts to try and detect this disease earlier. For instance, clinicians have started focusing more on prodromal symptoms, which are early symptoms that appear before movement-related difficulties begin.
These symptoms include:
- Loss of smell, which can sometimes occur years before other symptoms
- Chronic constipation, without any other explanation
- Rapid eye movement behavior disorder, which causes sleep disturbances
Is It Parkinsons Disease Blood Test Might Tell
But new technique needs more study, researchers say
The potential blood test is not ready for prime time,Parkinsons disease experts said. But, it marks progress in the quest for an objective way to diagnose Parkinsons and similar conditions known as atypical parkinsonian disorders, they noted.
Parkinsons disease is a movement disorder that affects nearly 1 million people in the United States alone, according to the Parkinsons Disease Foundation.
The root cause is unclear, but as the disease progresses, the brain loses cells that produce dopamine a chemical that regulates movement. As a result, people suffer symptoms such as tremors, stiff limbs, and balance and coordination problems that gradually worsen over time.
Right now, there is no blood test, brain scan or other objective measure that can definitively diagnose Parkinsons, said James Beck, vice president of scientific affairs for the Parkinsons Disease Foundation.
In general, Parkinsons disease is diagnosed with a clinical exam, Beck explained.
The best person to make that call is a neurologist with expertise in movement disorders, according to Beck.
But, he said, even highly trained doctors initially get it wrong about 10 percent of the time.

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.
Mri In Parkinson’s Testing
One of the more common tests done during a neurologic workup is an MRI scan and one may think that in the investigation of a disease that affects the brain such as Parkinsons, this imaging test would be a necessity. In the context of Parkinsons disease, however, an MRI is not particularly helpful. It looks at the structure of the brain which, for all intents and purposes, appears normal in this disease. An MRI may, however, be indicated when symptoms appear in younger people or if the clinical picture or the progression of symptoms is not typical for Parkinsons. In these situations, MRI can be used to rule out other disorders such as stroke, tumors, hydrocephalus , and Wilsons Disease .

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.
Blood Test Would Detect Parkinsons In Early Stages
A group of researchers developed a blood test that would allow neurologists detect Parkinsons disease and track the illness as it progresses.
If successful, we expect our findings will translate into a valuable diagnostic tool for Parkinsons disease, said study co-author Judith Potashkin, professor of cellular and molecular pharmacology at Chicago Medical School, Rosalind Franklin University of Medicine and Science.
According to the Parkinsons Disease Foundation, it is estimated that 60,000 people in the United States are diagnosed with Parkinsons disease each year. Data from 2013, by the University Center for Health Sciences at the University of Guadalajara, reported more than 500,000 cases of this neurodegenerative condition in Mexico. The same year, an economic model of Parkinsons disease forecasted that cases in the worlds population will double by 2040.
Now days, this disease is still incurable. It can cause tremors and severely hamper movement. Although medications allow controlling the condition, it gets worse over the years and medications do not stop its progression.
The traditional method to diagnose Parkinsons is by analyzing symptoms. Currently, brain scans are available, allowing the analysis of imaging studies to detect the disease however, the information obtained from these devices may still be somewhat imprecise, Potashkin said.
The study was published in the Feb. 3 online issue of the Proceedings of the National Academy of Sciences.

Uams Movement Disorders Clinic To Offer Art For Parkinsons Classes In Little Rock Hot Springs
The Art for Parkinsons workshops, for which no experience is necessary and all materials will be provided, are scheduled for Oct. 11, Nov. 15 and Dec. 13 at St. Michaels Episcopal Church at 12415 Cantrell Road in Little Rock, and Oct. 13 at FBC Fitness at 2350 Central Ave. in Hot Springs.
Each session runs from 9:30 a.m. to noon, and a virtual component is available for those who are unable to participate in person. Participants are urged to wear comfortable clothes that they dont mind getting dirty and are encouraged to attend as many sessions as they wish.
Registration is required to attend. To register, contact Suzanne Dhall, Dr.PH., MSPH, CHES, a health educator in the UAMS Department of Neurology, at or by calling or texting 602-635-0739.
The classes were first offered in the spring and are returning due to popular demand, again in partnership with Arts Integration Services of Little Rock. Instructor Elly Bates, a painter by trade, guides participants as they experiment with different types of art mediums while following a theme, such as music or light.
Participants can take their finished artwork home or leave it behind to be included in an art show of work from all the fall sessions.
Research has shown that drawing or painting may help Parkinsons patients improve their motor skills, and patients have reported that it helps them control their tremors.
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.

What Tests Diagnose Parkinson’s Disease
There currently are no tests that can definitively diagnose Parkinsons Disease. A diagnosis is based on the clinical findings of your physician in combination with your report on the symptoms you are experiencing.
In situations where an older person presents with the typical features of Parkinsons and they are responsive to dopamine replacement therapy, there is unlikely to be any benefit to further investigation or imaging.
The Facts About Parkinsons Disease
Parkinsons disease is a progressive neurogenerative disease that causes nerve cells in the area of the brain that controls movement to weaken and/or die. While healthy neurons produce a chemical called dopamine, which the brain needs a certain amount of in order to regulate movement, weakened neurons produce lower levels of dopamine. What causes these neurons to weaken is currently unknown.
Some patients with Parkinsons disease also suffer from a decline in norepinephrine, a chemical that transmits signals across nerve endings and controls various functions, such as blood pressure and heart rate.
More than 10 million people worldwide are currently living with Parkinsons disease and nearly one million will be living with the disease in the United States this year, according to the Parkinsons Foundation.

What Are The Symptoms Of Parkinson’s Disease
The main symptoms of Parkinson’s disease are:
- tremor or shaking, often when resting or tired. It usually begins in one arm or hand
- muscle rigidity or stiffness, which can limit movement and may be painful
- slowing of movement, which may lead to periods of freezing and small shuffling steps
- stooped posture and balance problems
The symptoms of Parkinson’s disease vary from person to person as well as over time. Some people also experience:
- loss of unconscious movements, such as blinking and smiling
- difficulties with handwriting
- drop in blood pressure leading to dizziness
- difficulty swallowing
Many of the symptoms of Parkinson’s disease could be caused by other conditions. For example, stooped posture could be caused by osteoporosis. But if you are worried by your symptoms, it is a good idea to see your doctor.
Physical And Neurological Examination
Your doctor will conduct a physical and neurological examination. This can involve observing your behavior, movements, and mental state and conducting tests or asking you to perform certain exercises.
These are some of the symptoms of Parkinsons your doctor can determine visually:
- Fewer spontaneous movements or hand gestures
- Reduced frequency of blinking
- Tremors in your hands while they are at rest, often only in one hand
- Hunched posture or forward lean while walking
- Stiff movements
These are some of the exercises your doctor may ask you to do to evaluate your movements, balance, and coordination:
- Opening and closing your fist
- Tapping your fingers, toes, and heels
- Holding your arms out in front of you
- Moving your finger from one point to another
- Rotating your wrists or ankles
- Standing from a chair

Pattern Of Symptoms In Parkinsons Disease
While the motor symptoms are the current standard for diagnosing PD, research has shown that PD non-motor symptoms, particularly gastrointestinal symptoms and the reduced sense of smell, may begin years before the motor symptoms appear. When the motor symptoms show up in the body, they generally begin on one side of the body. This is called unilateral presentation. As the disease progresses, the symptoms may spread to the other side of the body as well.3,6
PD is a progressive disease, and the symptoms worsen over time. This progression of symptoms is also noteworthy when considering a diagnosis of PD.3
How Is Parkinson’s Disease Diagnosed
Your doctor will ask questions about your symptoms and your past health and will do a neurological exam. This exam includes questions and tests that show how well your nerves are working. For example, your doctor will watch how you move. He or she will check your muscle strength and reflexes and will check your vision.
Your doctor also may check your sense of smell and ask you questions about your mood.
In some cases, your doctor will have you try a medicine for Parkinson’s disease. If that medicine helps your symptoms, it may help the doctor find out if you have the disease.
There are no lab or blood tests that can help your doctor know whether you have Parkinson’s. But you may have tests to help your doctor rule out other diseases that could be causing your symptoms. For example:
- An MRI or CT scan is used to look for signs of a stroke or brain tumor.
- Blood tests check for abnormal thyroid hormone levels or liver damage.
Another type of imaging test, called PET, sometimes may detect low levels of dopamine in the brain. These low levels are a key feature of Parkinson’s. But PET scanning isn’t commonly used to evaluate Parkinson’s. That’s because it’s very expensive, not available in many hospitals, and only used experimentally.

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.
If Its Not Parkinsons Disease What Else Could It Be
There are several other conditions that might produce symptoms that can be mistaken for Parkinsons disease. Here are some possibilities:
- Medication side effects: Certain drugs can produce or exacerbate symptoms.
- Essential, or familial, tremor: This is a relatively common and benign cause of recurrent tremor and is often confused with the tremor of idiopathic Parkinsons. A general neurologist or movement disorder specialist is the best physician to help differentiate between these two conditions.
- A Parkinsonian syndrome: The symptoms of several neurologic conditions are similar to those of idiopathic Parkinsons, but they are often managed differently and often do not respond to the typical medications.
Remember: Only a general neurologist or movement disorder specialist can tell you with reasonable certainty if you have idiopathic Parkinsons. If for some reason you are not comfortable with the results of your first physician visit, getting a second opinion from another general neurologist or movement disorder specialist is always an option. It is important that you feel comfortable with your physician to ensure the best possible outcome for you.
Once you or your loved one has a diagnosis of Parkinsons disease, it is time to discuss treatment options with your physician.

Parkinsons Is A Clinical Diagnosis
It turns out that the clinical features of PD are unique to PD and often very easy to see via a neurologic exam in a doctors office. Rest tremor for example, is seen in virtually no other illness. The skill is being able to distinguish a rest tremor from other tremors, which neurologists are trained to do.
However, some people with PD do not have a rest tremor, which can make the diagnosis trickier. Nevertheless, some elements of the standard in-office neurologic exam are very characteristic, such as
- small handwriting, that decreases in size as the writing continues
- small, movements of the hands and the feet, worse on one side,
- characteristic stiffness of the arms and the legs, worse on one side,
- stooped posture
- the characteristic walk in which the whole foot is planted flat at one time instead of the heel being planted on the ground first
- the characteristic way of turning by taking multiple steps and not pivoting
If there are enough of these features present during an exam, with or without a rest tremor, especially if coupled with a history of certain non-motor symptoms that typically appear before the movement symptoms of PD, such as constipation, loss of smell and REM behavior sleep disorder, the practitioner will feel sure of the diagnosis.
