Gait & Balance Abnormalities
Parkinsons Disease Exam
Patients with Parkinsons disease can develop an alteration of the postural reflexes that causes instability in gait and balance control. Such alterations usually develop later in the course of the illness and are a major cause of disability, especially because of the high risk for falls that derives.
Using the exam to pick up postural instability is of the utmost importance for the management of patients with PD, since it will trigger either a medication adjustment or a physical therapy intervention both aimed at falls prevention.
We have three tests for this part of the PD exam:
1);;;; Standing up from a chair
2);;;; Free walking
3);;;; Provoked pull test maneuver for balance
Parkinson’s Disease Is A Movement Disorder
Parkinson’s disease is a movement disorder that is degenerative and chronic, and symptoms continue and generally worsen over time. The National Institute of Neurological Disorders and Stroke estimates about 50,000 people are diagnosed with PD each year in the U.S. The cause of PD is unknown. There is currently no cure, but there are several treatment options available to manage symptoms including medications and surgery.
What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms
Exercise: Exercise helps improve muscle strength, balance, coordination, flexibility, and tremor. It is also strongly believed to improve memory, thinking and reduce the risk of falls and decrease anxiety and depression. One study in persons with Parkinsons disease showed that 2.5 hours of exercise per week resulted in improved ability to move and a slower decline in quality of life compared to those who didnt exercise or didnt start until later in the course of their disease. Some exercises to consider include strengthening or resistance training, stretching exercises or aerobics . All types of exercise are helpful.
Eat a healthy, balanced diet: This is not only good for your general health but can ease some of the non-movement related symptoms of Parkinsons, such as constipation. Eating foods high in fiber in particular can relieve constipation. The Mediterranean diet is one example of a healthy diet.
Preventing falls and maintaining balance: Falls are a frequent complication of Parkinson’s. While you can do many things to reduce your risk of falling, the two most important are: 1) to work with your doctor to ensure that your treatments whether medicines or deep brain stimulation are optimal; and 2) to consult with a physical therapist who can assess your walking and balance. The physical therapist is the expert when it comes to recommending assistive devices or exercise to improve safety and preventing falls.

What Are The Symptoms
Each person is affected differently by Parkinsons disease and no two people will experience exactly the same symptoms. The impact of Parkinsons disease can be unpredictable and it is common for people to have good days and bad days.
The main symptoms of Parkinsons disease are:
- balance problems
- problems with posture
Other possible symptoms include difficulty initiating movement , a shuffling gait when walking, and freezing when trying to move . People might experience a loss of facial expression, speech problems , swallowing problems, bowel and bladder problems, difficulties at night and tiredness during the day. Skin can become greasy and people might experience excessive sweating. Sexual problems are common. People often experience depression and anxiety. Another common symptom is small handwriting .
Other less common symptoms can include pain and memory problems.
Definition And Differential Diagnosis
There are many manifestations of but the classical diagnostic symptoms are:
- slowness and poverty of movement
The physical signs of include:
- slowness of movement
- rest tremor.
At diagnosis, these signs are usually unilateral, but they become bilateral as the disease progresses. Later in the disease additional signs may be present including postural instability , cognitive impairment and orthostatic hypotension .
There is no single way to define Parkinsons disease or what is often called idiopathic Parkinsons disease in order to differentiate it from other causes of parkinsonism, such as multiple system atrophy and progressive supranuclear palsy .
is traditionally defined, pathologically, by the finding of Lewy bodies and degeneration of catecholaminergic neurones at post-mortem. Using a pathological definition of PD is problematic for a number of reasons:
- A pathological diagnosis is not practical in life.
- Lewy body inclusions in catecholaminergic neurones are seen in individuals without clinical evidence of ; it is presumed that these are pre-clinical cases.
- Lewy bodies have not been found in otherwise typical individuals with with Parkin mutations, although such rare young-onset genetic cases of PD might be said not to have idiopathic PD.
In recent years, attempts to define genetically have become possible with the discovery of monogenic forms of the disease. However, such families account for a very small proportion of cases.

Early Signs Of Parkinson’s
Early physical signs include the common motor symptoms: tremor, muscle rigidity and slowness. They may also include the following:
- Symptoms starting on one side of the body
- Change in facial expression
- Failure to swing one arm when walking
- Loss of sense of smell
Some of these symptoms are quite common and by no means exclusive to Parkinsons, so if you have some of them, it does not mean you have Parkinsons.
Further Assessments And Investigations
- Perform a cerebellar examination: if concerned about cerebellar pathology.
- Measure lying and standing blood pressure: autonomic abnormalities are a feature of Parkinsons disease and multiple system atrophy.
- Assess eye movements: vertical gaze palsy and slow saccadic eye movements are associated with progressive supranuclear palsy .
- Perform a cognitive assessment
- Analyze the drug chart: medications such as neuroleptics, dopamine blocking antiemetics and sodium valproate can induce secondary parkinsonism.

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 .
How Do I Prevent Falls From Common Hazards
- Floors: Remove all loose wires, cords, and throw rugs. Minimize clutter. Make sure rugs are anchored and smooth. Keep furniture in its usual place.
- Bathroom: Install grab bars and non-skid tape in the tub or shower. Use non-skid bath mats on the floor or install wall-to-wall carpeting.
- Lighting: Make sure halls, stairways, and entrances are well-lit. Install a night light in your bathroom or hallway and staircase. Turn lights on if you get up in the middle of the night. Make sure lamps or light switches are within reach of the bed if you have to get up during the night.
- Kitchen: Install non-skid rubber mats near the sink and stove. Clean spills immediately.
- Stairs: Make sure treads, rails, and rugs are secure. Install a rail on both sides of the stairs. If stairs are a threat, it might be helpful to arrange most of your activities on the lower level to reduce the number of times you must climb the stairs.
- Entrances and doorways: Install metal handles on the walls adjacent to the doorknobs of all doors to make it more secure as you travel through the doorway.

Diagnosing Early Onset Parkinsons Disease
There is no single test to detect Parkinsons. A diagnosis may be difficult and take a while. The condition is usually diagnosed by a neurologist based on a review of your symptoms and a physical exam.
A DaTscan to visualize your brains dopamine system may help confirm diagnosis. Blood tests and other imaging tests, such as an MRI scan, dont diagnose Parkinsons. However, they may be used to rule out other conditions.
Who Should Consider A Genetic Test For Parkinsons
There are two groups of people who might consider getting genetic testing and we will discuss each group separately.
Genetic testing for PD is a common request and a number of commercial labs perform panels of genetic testing for PD. You may ask: How can I test myself for Parksinons? Whether youre considering getting a genetic test through your doctor, or performing one at home, its important to note that at-home test dont map the entire gene for mutations. Genetic testing through your doctor will test for GBA, PARK7, SNCA, LRRK2, parkin and PINK1.
Both groups are faced with two questions: Should I get genetic testing? And if so, what should I do with the results? Before we address these two questions, we need to learn more about the complexity of genetic testing in PD.

How Is Parkinsons Disease Treated
There is no cure for Parkinsons disease. However, medications and other treatments can help relieve some of your symptoms. Exercise can help your Parkinsons symptoms significantly. In addition, physical therapy, occupational therapy and speech-language therapy can help with walking and balance problems, eating and swallowing challenges and speech problems. Surgery is an option for some patients.
Blood Test May Help Differentiate Parkinsons From Similar Diseases
The American Academy of Neurology is the world’s largest association of neurologists and neuroscience professionals, with 36,000 members. The AAN is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, concussion, Parkinson’s disease and epilepsy.

Blood Test May Help Distinguish Parkinsons From Similar Diseases
Researchers have found that people with Parkinsons disease have lower levels of a certain;protein;in their blood than people with similar diseases. The results suggest that testing for the protein might help doctors to accurately differentiate between PD and similar diseases early on. The study appears in the February 8 online edition of;Neurology.
Because there are no definitive diagnostic tests for Parkinson’s, the diagnosis can be unclear especially early on in the disease. ;When diagnosis is uncertain, some people may be diagnosed with parkinsonism,” which refers to a category of diseases, including Parkinson’s, that cause slowness of movement, stiffness and rest;tremor. Other diseases in the category include multiple system atrophy , progressive supranuclear palsy and corticobasal degeneration .
Earlier studies found that a spinal fluid test may help distinguish PD from these other diseases, but this test is difficult to do during a routine visit to the doctor.
- Blood levels of NfL protein were generally lower in people with PD and in healthy individuals than in people with other Parkinsonian disorders.
- This result held both for those recently diagnosed and those who had been living with their disease for four to six years.
- The test for NfL could not distinguish between MSA, PSP and CBD.

Brain Imaging Can Help With Diagnosis
Doctors use two tests that take detailed pictures of your brain. Each one may help your doctor make a diagnosis. These tests are:;
- PET scan: This shows how your brain functions. It shows how the brain uses sugar. This scan can help tell the difference between Parkinson’s and .;
- DaTscan: This shows problems with brain cells that make dopamine. Healthy brain cells light up during the test. Cells without enough dopamine appear dark. This scan can help your doctor tell the difference between Parkinson’s and a brain disease called .
Imaging studies are a newer way to diagnose Parkinson’s. However, not every healthcare facility can do them. It takes an experienced doctor to interpret the scans accurately. These scans also can be very expensive. Be sure to check with your insurance company ahead of time to see whether you are covered and what your out-of-pocket costs will be.;
What Is Parkinson’s Disease
Parkinsons disease occurs when;brain cells that make dopamine, a chemical that coordinates movement, stop working or die. Because PD can cause tremor, slowness, stiffness, and walking and balance problems, it is called a movement disorder. But constipation, depression, memory problems and other non-movement symptoms also can be part of Parkinsons. PD is a lifelong and progressive disease, which means that symptoms slowly worsen over time.
The experience of living with Parkinson’s over the course of a lifetime is;unique to each person. As symptoms and progression vary from person to person, neither you nor your doctor can predict which symptoms you will get, when you will get them or how severe they will be. Even though broad paths of similarity are observed among individuals with PD as the disease progresses, there is no guarantee you will experience what you see in others.
Parkinsons affects;nearly 1 million people in the United States;and;more than 6 million people worldwide.

What Is Parkinson’s Disease?
Dr. Rachel Dolhun, a movement disorder specialist and vice president of medical communications at The Michael J. Fox Foundation, breaks down the basics of Parkinson’s.
People Who Already Have Pd: Should I Get Tested And What Do I Do With The Results
Up until recently, even people with PD with a very extensive family history of PD would not necessarily receive genetic testing because there were no clear uses for the results. There has been research directed at figuring out whether PD caused by or associated with certain mutations have particular clinical characteristics . However, there remains so much variability in clinical characteristics even among people with the same PD mutation, that there are still no clear practical implications in knowing whether a PD patient harbors a particular mutation.; There is also, so far, no difference in treatment or management of PD whether or not the patient harbors one of the known mutations. That may change however, with the advent of clinical trials that target particular mutations.
There are two genes that have received particular attention recently because medications are being developed that target those with mutations of these genes.
GBAis a gene that increases the risk of developing PD. The gene encodes for the GBA enzyme, a protein used by the body to break down cellular products. Having two abnormal GBA genes causes Gauchers disease, which is characterized by the buildup of these cellular products resulting in fatigue, bone pain, easy bleeding and an enlarged spleen and liver. When a person inherits only one abnormal gene, he or she does not develop Gauchers disease, but does incur a small increased risk of PD. Most people with one mutated GBA gene do not develop PD.
Living With Parkinson’s Disease
Coming to terms with a diagnosis of Parkinson’s and living with the disease is challenging and will take a lot of adjustment. There are still things you can do that can help you to feel more in control of your situation and to stay positive. Some things that might help could include:
- choosing to lead a healthy lifestyle
- making informed decisions related to your treatment
- keeping a diary of your symptoms in preparation for meetings with health and social care professionals
- attending a self-management course
Consider The Age And Time Factor
Doctors also keep in mind other factors when diagnosing Parkinson’s. For instance:
- The disease is not common in people younger than 50.
- Diagnosing Parkinson’s can be tricky and may take time.
- Other diseases can cause similar symptoms. Your doctor will try to rule out other diseases that mimic Parkinson’s such as .;

From Evidence To Recommendation
The pathological studies emphasise the need for particular care in making a clinical diagnosis of . There is limited evidence to suggest that the UK Brain Bank Criteria have adequate sensitivity and specificity in comparison with post-mortem findings. The accuracy of diagnosis using the Brain Bank criteria increases as the condition progresses.
The availability of brain tissue has fostered much valuable research in recent years and should be encouraged in the future. Diagnostic information derived from post-mortem examination can also be of value to the families of individual patients.
should be diagnosed clinically and based on the UK Parkinsons Disease Society Brain Bank Criteria.
Clinicians should be encouraged to discuss with patients the possibility of tissue donation to a brain bank for purposes of diagnostic confirmation and research.
There Are : : : : : Stages Of Parkinson’s Disease
There are five stages of Parkinson’s disease, described with the most commonly used Hoehn and Yahr scale: – Stage one: Symptoms such as tremors or shaking on one side of the body- Stage two: Tremors or shaking one or both sides of the body; possible imbalance- Stage three: Noticeable balance impairment and slowing of motion- Stage four: Severe symptoms, disability; patient likely needs assistance- Stage five: Patient may be bedridden or wheelchair bound; needs constant care Another scale that may be used to describe symptoms of Parkinson’s disease is called the Movement Disorders Society-Unified Parkinson’s Disease Rating Scale . It is a four-part scale that measures motor movement in PD: non-motor experiences of daily living, motor experiences of daily living, motor examination, and motor complications.
