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.

What Are The Types Of Tremor
There are several types of tremor, including:
- Essential tremor, sometimes called benign essential tremor. This is the most common type. It usually affects your hands, but it can also affect your head, voice, tongue, legs, and trunk.
- Parkinsonian tremor, which is a common symptom in people who have Parkinson’s disease. It is usually affects one or both hands when they are at rest, but it can affect the chin, lips, face, and legs.
- Dystonic tremor, which happens in people who have dystonia. Dystonia is a movement disorder in which you have involuntary muscle contractions. The contractions cause you to have twisting and repetitive movements. It can affect any muscle in the body.
Treatment Of Essential Tremor
There is no cure for essential tremor. Treatment aims to suppress the involuntary movements. To identify the best treatment, you should consult with a Neurologist. Treatments can include:
- avoidance of known triggers, such as alcohol or caffeine
- some medications used to treat other medical conditions, such as heart disease and epilepsy these medications have been helpful in some cases
- other medications, including tranquillisers
- deep brain stimulation, a surgically implanted device that helps to short-circuit the impulses or brain waves causing the tremor
- brain surgery to alter the part of the brain causing the tremor has been successful in some cases
- MRI guided focused ultrasound
- regular monitoring and observation if the tremor is mild and doesnt stop the person from performing their usual activities, this may be the only treatment.
In some cases, alcohol may reduce the tremors. However, this is not a recommended treatment, because long-term consumption of alcohol has significant health risks.

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 .
Trouble Moving Or Walking
Do you feel stiff in your body, arms or legs? Have others noticed that your arms dont swing like they used to when you walk? Sometimes stiffness goes away as you move. If it does not, it can be a sign of Parkinson’s disease. An early sign might be stiffness or pain in your shoulder or hips. People sometimes say their feet seem stuck to the floor.
What is normal?If you have injured your arm or shoulder, you may not be able to use it as well until it is healed, or another illness like arthritis might cause the same symptom.

Imaging And Lab Tests
Your doctor may order some imaging tests and laboratory tests. Imaging tests can include computed tomography scans and magnetic resonance imaging scans. Laboratory tests can include blood tests and urine tests.
While these tests and scans will not help diagnose Parkinsons disease, they can help rule out other conditions that have similar symptoms.
Your doctor may also suggest that you get a dopamine transporter scan . This scan requires a single-photon emission computed tomography scanner. It involves an injection of a small amount of a radioactive drug so that your doctor can study the dopamine systems in your brain .
While a DaTscan cannot conclusively prove that you have Parkinsons, it can help confirm your doctors diagnosis and eliminate other conditions.
Passive Manipulation Of Limbs
To test for the presence of rigidity, we need to passively manipulate the limbs of the patient. However, If the disease is in its early stage or the symptoms are well controlled with medications, we may not be able to see rigidity. We will need to use some activation maneuvers, that basically consist in performing repetitive movements with the limb contralateral to the one that is being tested.
Also, there are two types of rigidity:
Lead-pipe rigidity: where the tone is uniformly and smoothly increased throughout the entire range of movement
Cogwheel rigidity: where a tremor is superimposed on the hypertonia, making the movement irregular due to intermittent increase and reduction of tone
Upper Extremity Testing
For the upper extremity the most sensitive joint where to check for rigidity is the wrist. To uncover rigidity, passively rotate the wrist and feel for a resistance to the movement. It is very important that the arm of the patient is fully relaxed when rotating the wrist. To do this, place your proximal hand under the patients forearm, while your distal hand grabs and rotates the wrist of the patient. When rigidity is present, the range of motion will be preserved but you will feel a resistance in performing the movement.

It is also possible to test for rigidity in the elbow by passively flexing and extending the forearm.

What Are The Surgical Treatments For Parkinsons Disease
Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.
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.

How Is Tremor Treated
Although there is no cure for most forms of tremor, treatment options are available to help manage symptoms. In some cases, a persons symptoms may be mild enough that they do not require treatment.
Finding an appropriate treatment depends on an accurate diagnosis of the cause. Tremor caused by underlying health problems can sometimes be improved or eliminated entirely with treatment. For example, tremor due to thyroid hyperactivity will improve or even resolve with treatment of thyroid malfunction. Also, if tremor is caused by medication, discontinuing the tremor-causing drug may reduce or eliminate this tremor.
If there is no underlying cause for tremor that can be modified, available treatment options include:
A new treatment for essential tremor uses magnetic resonance images to deliver focused ultrasound to create a lesion in tiny areas of the brains thalamus thought to be responsible for causing the tremors. The treatment is approved only for those individuals with essential tremor who do not respond well to anticonvulsant or beta-blocking drugs.
When people do not respond to drug therapies or have a severe tremor that significantly impacts their daily life, a doctor may recommend surgical interventions such as deep brain stimulation or very rarely, thalamotomy. While DBS is usually well tolerated, the most common side effects of tremor surgery include dysarthria and balance problems.
The Role Of A Parkinsons Physical Therapist
As you can see, there are a number of reasons why your Parkinsons symptoms may be getting worse after exercise and it may be hard to pinpoint exactly whats happening on your own. This is where seeing a Parkinsons trained physical therapist is incredibly beneficial. They can help you problem-solve your situation, personalize an exercise program and adapt it over time.
When Its Not Parkinsons: Non
Everyone has some amount of tremor. Physiologic tremors are common, barely noticeable amounts of shakiness that worsen when people are stressed, anxious, or have had too much caffeine. As long as the tremors are not significant and do not affect your day-to-day activities, they may be completely normal.
Even tremors that are not normal are not always caused by Parkinsons. They can be caused by a range of other conditions, which together are known as movement disorders.
Managing Depression In Parkinsons Disease
People with Parkinsons, family members and caregivers may not always recognize the signs of depression and anxiety. If you are experiencing depression as a symptom of Parkinsons, it is important to know it can be treated.
Here are some suggestions:
- For information and support on living well with Parkinsons disease, contact our Information and Referral line.
- As much as possible, remain socially engaged and physically active. Resist the urge to isolate yourself.
- You may want to consult a psychologist and there are medications that help relieve depression in people with Parkinsons, including nortriptyline and citalopram .

Gauging Speed Of Movement
Bradykinesia occurs in most people who have Parkinsons. It may cause a lack of spontaneous facial expression and fewer eye blinks per minute than usual, and your healthcare provider will look for these signs in your physical exam.
Your practitioner also may assess your speed of movement by asking you to open and close each hand or tap your index finger against your thumb repeatedly, making large movements as quickly as possible. In people with Parkinsons disease, the movement may start off fast and precise, but it will deteriorate quickly, becoming slow and limited.
Gait is also another way to test for this. Observing a patient while they walk, noting the length of their stride as well as the speed at which they move, can tell healthcare providers quite a bit. Lack of arm swing is also a feature that appears fairly early in those with Parkinsons.

Symptoms Of Parkinsons Disease
Parkinsons has four main symptoms:
- Tremor in hands, arms, legs, jaw, or head
- Muscle stiffness, where muscle remains contracted for a long time
- Slowness of movement
- Impaired balance and coordination, sometimes leading to falls
Other symptoms may include:
The symptoms of Parkinsons and the rate of progression differ among individuals. Early symptoms of this disease are subtle and occur gradually. For example, people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly, or that their handwriting is slow and looks cramped or small. Friends or family members may be the first to notice changes in someone with early Parkinsons. They may see that the persons face lacks expression and animation, or that the person does not move an arm or leg normally.
People with Parkinson’s disease often develop a parkinsonian gait that includes a tendency to lean forward take small, quick steps and reduce swinging their arms. They also may have trouble initiating or continuing movement.
Symptoms often begin on one side of the body or even in one limb on one side of the body. As the disease progresses, it eventually affects both sides. However, the symptoms may still be more severe on one side than on the other.
What Are The Results
Successful DBS is related to 1) appropriate patient selection, 2) appropriate selection of the brain area for stimulation, 3) precise positioning of the electrode during surgery, and 4) experienced programming and medication management. DBS for essential tremor may significantly reduce hand tremor in 60% to 90% of patients and may improve head and voice tremor.
Patients report other benefits of DBS. For example, better sleep, more involvement in physical activity, and improved quality of life.

Your Cat Is Experiencing Feline Infectious Peritonitis
When your cat is affected by Feline Infectious Peritonitis disease, it can shake its head like Parkinsons. FIP is a viral infection caused mostly in multiple-cat environments.
When your cat is affected by FIP, it may show signs like watery eyes, nasal discharge, and head shaking. It also loses its appetite and falls into depression. Sometimes, it can cause diarrhea and breathing difficulty.
What Is A Tremor
A tremor is a rhythmic shaking movement in one or more parts of your body. It is involuntary, meaning that you cannot control it. This shaking happens because of muscle contractions.
A tremor is most often in your hands, but it could also affect your arms, head, vocal cords, trunk, and legs. It may come and go, or it may be constant. Tremor can happen on its own or be caused by another disorder.

What Is A Parkinsonian Tremor
A tremor is an involuntary, uncontrollable muscle contraction, which manifests as shaking in body parts, most commonly the hands. About 70 percent of Parkinsons disease patients experience tremors in the early stages of the disease. There are two types of tremors: Resting tremors and action tremors.
What Are The Risk Factors For Parkinsons
There are a few known risk factors for Parkinsons. These include:
- having a family history of Parkinsons
- being over 60 years
- being a male
- having been exposed to herbicides, pesticides, and other toxins
Its important to note that these risk factors only cause a slight increase in risk. Having one or more risk factors isnt an indicator youll develop Parkinsons. However, if youre concerned about your risk for Parkinsons, talk with a doctor.

Symptoms Of Parkinsons Tremor
Like most symptoms of Parkinsons disease, it is usually asymmetric. It starts generally on one side, which remains the more affected side forever. Having a tremor on one side does not mean that the other side will begin to shake as well. Many people have tremor on only one side throughout their illness.
Is Head Tremor The Same As Essential Tremor
Head tremor is often described as an oscillation of the head, causing it to move side to side or up and down. The tremor can be rhythmic like a pendulum or irregular and more pronounced. While head tremors can be one of many types of tremors experienced by those with essential tremor, they are also seen in patients with dystonia.

Tremor In Other Conditions
While tremor is a common symptom of Parkinsons, it can also be a symptom of other conditions, most notably essential tremor. The main difference between Parkinsons tremor and most other types of tremor is that in Parkinsons resting tremor is most common. Other conditions are usually characterized by action tremor, which tends to lessen at rest and increase when youre doing something, like trying to make a phone call or take a drink.
Tremors of the head and voice are also common in essential tremor but rare in Parkinsons.
Confusion With Essential Tremor
The tremor of Parkinsons disease is often confused with the tremor of a condition called Essential Tremor, or Benign Familial Tremor. Katherine Hepburn had Essential Tremor, and was originally misdiagnosed with Parkinsons. Ronald Reagan, also, had Essential Tremor. Both had a head tremor and a vocal tremor. With Essential Tremor, the hands are most commonly involved, followed by the head and then the voice. Essential Tremor can cause the jaw to tremor, and it may be difficult to figure out if a jaw tremor is from Essential Tremor or Parkinsons. Unfortunately, some people may have both disorders. Some authorities believe that there is, in fact, an increased association between the two conditions, so that more people with Parkinsons disease have Essential Tremor than would be expected by chance alone, but this has not been established.
