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
Early Signs And Symptoms Of Parkinsons Disease: An Overview
Parkinsons Disease is a neurological condition that typically affects patients above the age of 60. The early signs and symptoms of Parkinsons Disease can be hard to spot, since they often appear sporadically, and are mild during their initial appearance. Timely diagnosis and intervention is crucial for optimum treatment. Here, we take a closer look at the early signs of Parkinsons Disease.
What Is The Pattern Of Disease In Pd
The onset of PD usually occurs in patients in their sixties, and the disease progresses slowly. Although PD eventually results in severe disability and often dementia, life expectancy is not significantly shortened. Death is often due to secondary problems associated with the disease such as falls, pneumonia, aspiration, and immobility.
Figure 2. The onset of Parkinsons disease usually occurs in patients older than 60 and the disease progresses slowly.

Coping With Parkinsons Disease
Men and women often have different responses to the experience of living with PD. For example, women with PD tend to experience a higher rate of depression than men with PD do. As a result, they may receive medications for these conditions more often.
A 2020 study evaluated 64 people with PD for anxiety and depression. Depression was more common in women, individuals with a lower socioeconomic status, or those with a history of depression. Anxiety was more common in younger individuals or those with a history of anxiety.
A 2018 study assessed anxiety in 311 people with PD. Women with PD experienced more persistent and episodic anxiety.
Men with PD are more likely to exhibit behavioral problems and aggression, such as inappropriate or abusive behavior. Some research has reported that antipsychotic medications are prescribed at higher rates in men and in people with PD, specifically if theyre experiencing dementia.

Symptoms Of Parkinson’s Disease
There are several symptoms of Parkinson’s Disease, most of the affecting motor functions of the nervous system. Parkinsons disease is a progressive degenerative disease, meaning that the cell death and resulting dysfunction in the brain begin slowly and continue in a progressive way. They slowly get more pronounced over time. Therefore, Parkinson’s disease symptoms generally present slowly and subtly. As time progresses the symptoms will become more pronounced and severe. Additionally, further symptoms that were not first evident can become apparent.
The classic “triad” of symptoms of Parkinson’s disease include tremor, rigidity and bradykinesia because they are common in patients with the disease and are some of the first symptoms to present.
Tremor is an involuntary shaking of the body, usually most pronounced at rest . Other forms of tremor sometimes seen include a “pill-rolling” tremor.
Rigidity is an increased tone of muscles, meaning the passive movement of the extremities is more difficult than normal.
Bradykinesia means “slow movement”. Most movements are slowed. This can particularly affect fine motor control, making fine motor skills quite difficult. This can also be evident in the general lack of excessive movements, such as decreased expressive gestures and decreased facial movement and facial expressions .
Other symptoms include freezing , akinesia , inbalance, impaired posture, speech changes, abnormal gait , and others.

Stiffness And Slow Movement
Parkinsons disease mainly affects adults older than 60. You may feel stiff and a little slow to get going in the morning at this stage of your life. This is a completely normal development in many healthy people. The difference with PD is that the stiffness and slowness it causes dont go away as you get up and start your day.
Stiffness of the limbs and slow movement appear early on with PD. These symptoms are caused by the impairment of the neurons that control movement. A person with PD will notice jerkier motions and move in a more uncoordinated pattern than before. Eventually, a person may develop the characteristic shuffling gait.
Some Parkinsons Treatment Options
Parkinsons disease has no cure, but there are treatment options to control your symptoms and improve your quality of life which include:
- Medication. Levodopa and other medications, which are trying to boost dopamine . There are number of those medications which can be used alone or in combination. Although many of those medications can help you significantly control your motor symptoms , you might also experience side effects and diminished efficacy over time.
- Physical, occupational, and speech therapy are usually part of your treatment plan and can improve your balance, mobility, ability to do daily tasks, and speech.
- Deep brain stimulation is a surgery performed by a neurosurgeon, and in indicated patients can help with motor symptoms, though non-motor symptoms, such as falls, constipation, low blood pressure and incontinence do not improve.
- Tai Chi is a Chinese martial art that may help sufferers regain some of their balance and strength, as well as decrease the risk of falling. Dance, such as a Zumba, may also help, as can using a stationary bicycle and rock steady boxing.
Many treatment options for Parkinsons are most effective when used in conjunction with others such as taking medication and doing physical therapy.

How Much Does Parkinsons Disease Change Someones Personality
The Parkinsons Foundation has shared 10 early signs of PD, including tremor, small handwriting, and loss of smell.
While younger people with early-onset PD may have some of the same signs and symptoms as older individuals, the onset may look different, so their issues may not be attributed to PD.
The American Parkinson Disease Association notes that, Because the majority of people who get Parkinsons disease are over the age of 60, the disease is often overlooked in younger people, leading many to go undiagnosed or misdiagnosed for extended periods of time.
My sister was finally referred to a neurologist at the Cleveland Clinic Center for Neurological Restoration in Ohio, as her symptoms slowly but consistently progressed. After multiple tests, including an MRI, cognitive testing, and a movement and balance analysis, she was diagnosed with PD.
One of Bevs early signs was weakness in her left hand, which she attributed to carpal tunnel syndrome. She regularly conducted echocardiograms and electrocardiograms, which required a lot of constant hand movement. She did not have stiffness or balance issues initially, but she did have a slight head tremor.
As Bevs PD progressed, she noticed that her writing was changing. She now has stage 3 PD and said, Sometimes I cant read my own writing. I feel like it looks like chicken scratch!
Bev also has cognitive issues, mostly related to her short-term memory.

Seven Signs Of Early Onset Of Parkinsons
There are a number of symptoms that can warn us about early onset of Parkinsons. There are several characters, but we will focus on these seven:
- Sleep disorders. The most common sleep disorders are insomnia , restless legs syndrome and REM sleep behavior syndrome.
- Depression. It is one of the first symptoms that occurs and it is actually considered as an early indicator of this disease.
- Other mood swings. In addition to depressive symptoms, anxiety and apathy are very common. These symptoms can affect the desire to seek help and a solution in a negative way.
- Cognitive changes. Many people with early-onset Parkinsons usually find it difficult to do more than one thing at a time. Poor performance of tasks, slow thinking, difficulty focusing and concentrating, memory problems and dementia are all symptoms of early onset of Parkinsons.
- Tremors. Although they usually begin in the hands, they start in other patients in the jaw or in the feet. The most characteristic of these tremors is that they occur when resting.
- Bradykinesi. This is a gradual loss of spontaneous movement. In general, movements simply become slower. This is one of the most debilitating and frustrating symptoms for the people affected.
- Exhaustion. With early onset of Parkinsons, the patient feels tired all the time without having exhausted himself.

How Is It Treated
At this time, there is no cure for Parkinsons disease. But there are several types of medicines that can control the symptoms and make the disease easier to live with.
You may not even need treatment if your symptoms are mild. Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctor will adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.
Levodopa is the best drug for controlling symptoms of Parkinsons. But it can cause problems if you use it for a long time or at a high dose. So doctors sometimes use other medicines to treat people in the early stages of the disease.
The decision to start taking medicine, and which medicine to take, will be different for each person. Your doctor will be able to help you make these choices.
In some cases, a treatment called deep brain stimulation may also be used. For this treatment, a surgeon places wires in your brain. The wires carry tiny electrical signals to the parts of the brain that control movement. These little signals can help those parts of the brain work better.
There are many things you can do at home that can help you stay as independent and healthy as possible. Eat healthy foods. Get the rest you need. Make wise use of your energy. Get some exercise every day. Physical therapy and occupational therapy can also help.

Whats Different About Young
The age of diagnosis matters for a variety of reasons, from probable causes of early cases to symptoms and treatment:
- Genetics. As with any case of Parkinsons disease, the exact cause is usually unknown. That said, The young-onset cases of Parkinsons disease are, on average, a bit more likely to be familial or genetic, says Gregory Pontone, M.D., director of the Johns Hopkins Movement Disorders Psychiatry Clinic.
- Symptoms. In many patients with YOPD, dystonia is an early symptom. People with YOPD also report more dyskinesia . They also tend to exhibit cognitive problems, such as dementia and memory issues, less frequently.
- Progression. Patients with young-onset Parkinsons appear to have a slower progression of the disease over time, says Pontone. They tend to have a milder course, staying functional and cognitively intact for much longer.
- Treatment. Most patients with Parkinsons take the medication levodopa. However, other drugs, such as MAO-B inhibitors, anticholinergics, amantadine, and dopamine receptor agonists, may be used before levodopa.

Signs Of Early Onset Of Parkinsons Disease
Early onset of Parkinsons disease begins before the age of 50. It is a neurodegenerative disorder that affects the nervous system. It causes damage and subsequent deterioration of the neurons located in the black matter. The average age for onset of Parkinsons is 60, and the cases increase significantly with age. However, about 5 to 10 percent of people with Parkinsons disease experience early onset of Parkinsons before they turn 50.
Mutations of certain genes, such as the Parkin gene, can contribute to its early onset. People with one or more close family members with Parkinsons are at greater risk of developing the disease.
Overall, the risk of developing the disease is only 2 to 5 percent, unless the disease is part of family history. It is estimated that between 15 and 25 percent of people with Parkinsons know that they have a family member with the disease.
In very rare cases, the symptoms of Parkinsons may occur in people under the age of 20. This is known as youthful Parkinsons. It usually begins with the symptoms of dystonia and bradykinesia. The drug, levodopa, can often improve these symptoms.

Outside The Realm Of Dopamine
Unfortunately, levodopa therapy doesn’t satisfactorily control many clinical aspects of Parkinson’s disease, presumably because they result from degeneration of nondopaminergic parts of the nervous system.
Figure 4. Tissues taken from the substantia nigra pars compacta normally show a high density of dark-colored nerve cells under microscopic inspection . But people with Parkinsons disease experience extensive loss of such pigmented neurons . An enlarged view of one of the surviving neurons reveals a Lewy body , an inclusion within the cell containing dysfunctional protein masses.

Researchers are discovering that the pathology of the disease is far more extensive than their predecessors initially appreciated and is not restricted to dopaminergic nerve cells in the substantia nigra pars compacta. Indeed, they have identified signs of neurodegeneration with the development of Lewy bodies in nondopaminergic regions of the brain, the spinal cord and the peripheral nervous system, which use a variety of different neurotransmitters . Strangely, some regions of the brain can suffer profound nerve-cell loss with Lewy-body formation, while neighboring areas are completely spared, indicating that some as-yet-unknown factors make only certain nerve cells vulnerable to degeneration in Parkinson’s disease.

What Are The Three Motor Signs Of Parkinson Disease
The classic motor features of Parkinson disease typically start insidiously and emerge slowly over weeks or months, with tremor being the most common initial symptom. The 3 cardinal signs of Parkinson disease are resting tremor, rigidity, and bradykinesia. Postural instability is sometimes listed as the fourth cardinal feature. However, balance impairment in Parkinson disease is a late phenomenon, and in fact, prominent balance impairment in the first few years suggests that Parkinson disease is not the correct diagnosis.
Diagnosis And Management Of Parkinsons Disease
There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.
No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.
People can manage their Parkinsons disease symptoms through:
- seeing a Doctor who specialises in Parkinsons
- multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
- deep brain stimulation surgery .

What Is Rem Behavior Disorder And How Is It Connected To Parkinson’s
A: REM behavior disorder is different than other sleep problems, like insomnia. People who have it may jerk or kick it’s as though they are acting out their dreams. In a similar pattern to anosmia, people with idiopathic REM sleep behavior disorder have at least a 50 percent chance of eventually developing Parkinson’s disease.
How Is Constipation An Early Warning Sign Of Parkinson’s It’s Such A Common Problem
A: It’s not as specific as other prodromal symptoms, like anosmia. The rate at which people with chronic and unexplained problems with constipation develop Parkinson’s disease is not as easy to pin down. But if someone has unexplained, persistent constipation, it should at least be noted, as it could be considered prodromal.

Categories Of Parkinsons Disease
Two categories of Parkinsons disease have been distinguished as the idiopathic or primary PD and secondary PD. Idiopathic or Primary PD is defined by the presence of a certain symptom-complex but its main cause is still unknown.
Idiopathic PD falls under the ICD-10 Category G20. Secondary PD has similar symptoms to PD but the cause is known. These diseases fall under ICD-10 Category G21 .
Secondary PD includes the malignant neuroleptic syndrome as well as other drug-induced Parkinsonism such as those caused by neuroleptic drugs , antiemetic agents , gastro-intestinal anti-motility drugs , antihypertenstive drugs and some calcium-channel blockers.
Other secondary Parkinsonism is caused by the environmental factors such as toxicity, trauma, metabolic derangement and brain tumor. The knowledge of the cause of Parkinsons symptoms hints the best treatment. For instance, Parkinsonism induced by drug usually disappears within weeks to months after medication is discontinued.
However, recent studies have reported that symptoms can be permanent in about 15% of people. The diagnosis of the two types of Parkinsons disease is the same but both have different medical treatment and prognosis. In addition, supporting evidence has also shown that both idiopathic and secondary PDs have similar impact on the individuals .
Early Symptoms Of Parkinsons Can Be Overlooked
Symptoms of Parkinsons disease are divided into 2 groups: motor symptoms and non-motor symptoms.
Early non-motor symptoms can be subtle and its possible to overlook them as signs of Parkinsons: for example, anxiety and depression, fatigue, loss of smell, speech problems, difficulty sleeping, erectile dysfunction, incontinence and constipation. Another sign of Parkinsons is handwriting that becomes smaller.
Motor symptoms of Parkinsons can include tremor , slowness of movement , muscle rigidity and instability .
Its possible for non-motor symptoms to start occurring up to a decade before any motor symptoms emerge. Years can pass before symptoms are obvious enough to make a person to go to the doctor.
Theres no one size fits all when it comes to Parkinsons disease different people will experience different symptoms, and of varying severity. One in 3 people, for example, wont experience tremor.
On average, 37 people are diagnosed with Parkinsons every day in Australia. Parkinsons Australia
