Physical Exam And Medical History
As a first step, your doctor will observe and ask you about the signs and symptoms youre experiencing.
If any of these symptoms began on one side of your body, or if you experience a tremor when your arm is at rest, Parkinson’s may be strongly suspected.
Most likely, your doctor will also ask you about any other symptoms you may have, even if they seem unrelated.
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.

What Are The Primary Motor Symptoms Of Parkinsons Disease
There are four primary motor symptoms of Parkinsons disease:
- bradykinesia
- postural instability
Observing two or more of these symptoms is the main way that physicians diagnose Parkinsons.
It is important to know that not all of these symptoms must be present for a diagnosis of Parkinsons disease to be considered. In fact, younger people may only notice one or two of these motor symptoms, especially in the early stages of the disease. Not everyone with Parkinsons disease has a tremor, nor is a tremor proof of Parkinsons. If you suspect Parkinsons, see a neurologist or movement disorders specialist.
Introducing an easier way to track your symptoms and manage care.
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.

What Medications Are Used To Treat Parkinsons Disease
Medications are the main treatment method for patients with Parkinsons disease. Your doctor will work closely with you to develop a treatment plan best suited for you based on the severity of your disease at the time of diagnosis, side effects of the drug class and success or failure of symptom control of the medications you try.
Medications combat Parkinsons disease by:
- Helping nerve cells in the brain make dopamine.
- Mimicking the effects of dopamine in the brain.
- Blocking an enzyme that breaks down dopamine in the brain.
- Reducing some specific symptoms of Parkinsons disease.
Levodopa: Levodopa is a main treatment for the slowness of movement, tremor, and stiffness symptoms of Parkinsons disease. Nerve cells use levodopa to make dopamine, which replenishes the low amount found in the brain of persons with Parkinsons disease. Levodopa is usually taken with carbidopa to allow more levodopa to reach the brain and to prevent or reduce the nausea and vomiting, low blood pressure and other side effects of levodopa. Sinemet® is available in an immediate release formula and a long-acting, controlled release formula. Rytary® is a newer version of levodopa/carbidopa that is a longer-acting capsule. The newest addition is Inbrija®, which is inhaled levodopa. It is used by people already taking regular carbidopa/levodopa for when they have off episodes .
Four Cardinal Signs Of Parkinsons Disease
As stated earlier, problems with muscle control and movement are the most common signs of an onset of this disease. Specifically, thefour cardinal signs of Parkinsons Disease are:
These three may occur at the same time. For example, a person with PD may exhibit the following:
- Takes a long time to react when called
- Rises slowly from a sitting position
- Unable to quickly open and close their hands

How Is Parkinsons Treated
Parkinsons disease in itself doesnt have a cure. However, doctors can slow the progression of the disease and treat some of the symptoms. Lifestyle changes, medication, physical therapy, occupational therapy, speech therapy, rest, and other types of therapy may prevent the disease from advancing to stage five or at least delay the advancement.

Stage Four Of Parkinsons Disease
In stage four, PD has progressed to a severely disabling disease. Patients with stage four PD may be able to walk and stand unassisted, but they are noticeably incapacitated. Many use a walker to help them.
At this stage, the patient is unable to live an independent life and needs assistance with some activities of daily living. The necessity for help with daily living defines this stage. If the patient is still able to live alone, it is still defined as stage three.
What Is Parkinsons Disease
Parkinsons Disease, sometimes called PD, is a disorder of the nervous system.
The brain has a substance called dopamine produced by the substantia nigra,found in the cells of the midbrain, the upper part of the brainstem. The disease targets and damages the cells of the substantia nigra. When the cells are reduced by 60 to 80 percent, a person starts to show symptoms of PD.
Since dopamine is a chemical that is vital for the smooth coordination of muscles and movement, a persons inability to properly do common activities like walking and writing are some of the initial symptoms of PD. Moreover, Parkinsons is a chronic and progressive disease, which means that its symptoms worsen as the illness develops.

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 .
Stooping Or Hunching Over
Are you not standing up as straight as you used to? If you or your family or friends notice that you seem to be stooping, leaning or slouching when you stand, it could be a sign of Parkinson’s disease.What is normal? If you have pain from an injury or if you are sick, it might cause you to stand crookedly. Also, a problem with your bones can make you hunch over.

What Are The Stages Of Parkinsons
- Stage 1 Symptoms are seen on one side of the body only.
- Stage 2 Symptoms are seen on both sides of the body. There’s no impairment of balance.
- Stage 3 Balance impairment has begun. In this mild to moderate stage of the disease, the person is still physically independent.
- Stage 4 This stage is marked by severe disability. The person is still able to walk or stand unassisted but may need a walker to get around.
- Stage 5 The person requires a wheelchair or is bedridden unless assisted in standing and walking.
Additional reporting by Ingrid Strauch.
What Are The Risk Factors Of Parkinsons Disease
Dr. Almasri: We dont know what causes Parkinsons, so age is the only risk factor, and its an indirect one. Most people are diagnosed in their 60s, with some as early as age 40. Michael J. Fox was diagnosed early in his 30s. And hes done a lot to promote PD research, which is why hes often known as the face of Parkinsons.
While diagnosis doesnt typically happen until later in life, the brain-cell death that causes PD actually starts early in adulthood. Most people wont notice symptoms until 80% of those cells are gone. As a progressive disease, PD can start in the fingers on one side of your body, extend to your arms/hands, and then move to your other leg or hand. It can be 15 years before it shows up as a full-blown disease.

What Are The Risk Factors Of Developing Dementia After Parkinsons Disease
Certain patients with Parkinsons disease are at higher risk of developing dementia than others. Some of the vital risk factors for developing dementia after Parkinsons disease may include older age, severity of symptoms and presence of mild cognitive impairment. Other additional symptoms which act as risk factor for developing into full fledged dementia include-
- Excessive sleepiness in the daytime.
- Presence of hallucination in the absence of other dementia related symptoms.
- Presence of postural instability and gait which include freezing that occurs suddenly, difficulty in initiating movement and problems with balancing and frequent falling.
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.

How Is It Diagnosed
Diagnosing Parkinson’s disease is mostly a clinical process, meaning it relies heavily on a healthcare provider examining your symptoms, asking you questions and reviewing your medical history. Some diagnostic and lab tests are possible, but these are usually needed to rule out other conditions or certain causes. However, most lab tests aren’t necessary unless you don’t respond to treatment for Parkinson’s disease, which can indicate you have another condition.
Parkinsons Disease Symptoms Associated Symptoms
Having previously looked at the 4 Cardinal Signs related to Parkinsons disease symptoms, we now will address the issue concerning Parkinsons disease associated symptoms.
Associated symptoms useful for Parkinsons disease diagnosis are varied and although the side effects of medication can contribute, these symptoms are typically linked to autonomic failure:

Parkinsons disease is a neurodegenerative disorder that affects predominantly dopamine-producing neurons in a specific area of the brain called substantia nigra. Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinson’s disease. What are the four cardinal signs of Parkinsons disease to spot?
Medications Used For Treating Psychosis
Antipsychotic agents are designed to balance abnormal chemical levels in the brain. Up until the 1990s, the use of antipsychotics in PD was controversial because the drugs used until that time work by reducing excess dopamine. This alleviated psychosis but caused dramatic worsening of PD motor symptoms.
Fortunately, medications that are better tolerated by people with PD are now available. Today, there are three antipsychotic medications considered relatively safe for people with PD: quetiapine , clozapine and the newest agent, pimavanserin . They cause limited worsening of PD while treating hallucinations and delusions.

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.
What Treatments Are Available
Many Parkinsons patients enjoy an active lifestyle and a normal life expectancy. Maintaining a healthy lifestyle by eating a balanced diet and staying physically active contributes to overall health and well-being. Parkinsons disease can be managed with self-care, medication, and surgery.
Self careExercise is as important as medication in the treatment of PD. It helps maintain flexibility and improves balance and range of motion. Patients may want to join a support group and continue enjoyable activities to improve their quality of life. Equally important is the health and well being of the family and caregivers who are also coping with PD. For additional pointers, see Coping With Parkinsons Disease.
These are some practical tips patients can use:
Medications There are several types of medications used to manage Parkinsons. These medications may be used alone or in combination with each other, depending if your symptoms are mild or advanced.
After a time on medication, patients may notice that each dose wears off before the next dose can be taken or erratic fluctuations in dose effect . Anti-Parkinsons drugs can cause dyskinesia, which are involuntary jerking or swaying movements that typically occur at peak dosage and are caused by an overload of dopamine medication. Sometimes dyskinesia can be more troublesome than the Parkinsons symptoms.

Managing Slowness Of Movement
Levodopa is the medication most commonly given to control the movement symptoms of Parkinsons. Dopamine agonists, MAO-B inhibitors, and amantadine can also be used alone or in combination with other medications to improve slowness, as well as stiffness and tremor.
If you experience off periods when bradykinesia and other symptoms are worse, adjusting the dose or schedule of your medication could help. Talk to your healthcare provider before making any changes to your medications.
In addition to medications, exercise should be part of your treatment plan for all Parkinsons symptoms. Staying active is an essential element of living well with PD.
Research also suggests that music therapy can reduce bradykinesia and other Parkinson’s symptoms.

Causes Of Parkinsons Disease
Parkinsons disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain.
Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinsons disease.
Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.

Stages Of Parkinsons Disease
Doctors use different rating scales to assess a patients case but the most commonly used is theHoehn and Yahrscale, which divides the symptoms into five stages.
Stage 1. Mild symptoms that affect only one side of the body and do not impair the daily life of a person.
Stage 2. Symptoms develop into secondary motor types and eventually affect both sides of the body. This stage evolves months or years after the first stage starts.
Stage 3. Symptoms compromise the daily activities of a person although he or she can still function independently when doing basic tasks like eating and bathing. Movement becomes considerably slow and a persons balance becomes compromised. At this stage, the symptoms are so marked that there is no doubt about the diagnosis of PD.
Stage 4. The patient may still manage certain activities like walking unassisted or with tools like walkers. However, the symptoms become so debilitating that the patient needs assistance with daily living.
Stage 5. The disease has become so advanced that the patient is usually confined to a bed or a wheelchair. This stage requires around-the-clock assistance and monitoring since the patient has a high risk of getting into an accident. This is especially needed if the patient develops hallucinations or dementia.
About 50% to 80% of those with Parkinsons eventually experience dementia as their disease progresses.
