Early Detection Is Important
Some people never share with their doctor a subtle symptom, such as a periodic involuntary jerk of a finger, because it doesnt cross their minds as something worrisome.But Dr. Joseph advises not to wait until symptoms progress to get checked out. That finger jerk could progress into a full-blown tremor.Dr. Joseph, who was inspired to treat patients with Parkinsons when she saw a deep brain stimulation procedure stop a patients tremor in medical school, wants you to know that its normal to feel scared about having symptoms evaluated for a possible Parkinsons diagnosis.But she encourages you to be brave and get an exam for this important reason: People who start Parkinsons treatment earlier have less disability and longer lifespans!
Symptoms Of Parkinsons Disease
You can attribute the symptoms of Parkinsons to a deficiency of a chemical in your brain called dopamine. The four classic motor symptoms of Parkinsons include:
Shaking and tremors while you are resting is typically the first sign of Parkinsons disease, but about one-third of patients wont experience those symptoms. These symptoms tend to be worsened by emotional and physical stress. Sleep or moving can help reduce these issues.
Parkinsons disease is both chronic and progressive with symptoms generally getting worse as time goes on. As it progresses, other disabilities can develop, including:
- Difficulty talking and swallowing
- A sudden inability to move,
Some sufferers also have symptoms that dont affect their motor skills, including:
- Mental health issues such as anxiety, depression and memory loss
- Loss of smell
- Trouble sleeping, including thrashing and other sudden movements
- Change in blood pressure
Treatment Options For Early Onset Parkinsons Disease
Parkinsons treatment aims to slow the diseases progression. Medication treatment options may include the following:
- Levodopa is a chemical thats converted to dopamine in the brain. People with early onset Parkinsons may experience more negative side effects, such as involuntary movements.
- MAO-B inhibitors can help reduce the breakdown of dopamine in the brain.
- Catechol-O-methyltransferase inhibitors can help extend Levodopas effects on the brain.
- Anticholinergics can help reduce tremors.
- Amantadine may be used to improve muscle control and relieve stiffness.

Signs And Symptoms Indicating That The Patient May Not Have Classic Pd
There are several other Parkinsons-like diseases that, while similar to PD, are not technically classified as PD. These diseases may not respond as well to treatment as PD does:
- Progressive supranuclear palsy
- Dementia with Lewy bodies
- Corticobasal degeneration
Be sure to evaluate your patient for signs and symptoms which may indicate that the patient does not have classic PD. These signs and symptoms may include urinary or fecal incontinence, disabling orthostatic hypotension, early onset , poor response to PD medications, symmetry of findings early in the disease, and a lack of tremor.

Early Onset Of Parkinsons
When we think of someone with Parkinsons, we usually see someone with hand tremors before us. They walk very slowly with their backs slightly bent. Their bodies are a bit stiff. It is true that this picture is not far from the truth.
However, the tremors, stiffness and slow gait are not the only symptoms of Parkinsons disease. In addition to these and other motor symptoms, there are also a large number of symptoms that are not associated with motor skills.
These non-motor symptoms are cognitive, behavioral, and emotional changes. They can limit the patients daily life.
However, it is not uncommon for symptoms of Parkinsons, both associated with motor skills and not, to show up in very young individuals. Although the disease is more common in the elderly, it is not limited to them.
In the case of juvenile Parkinsons, symptoms not related to motor skills are probably the least typical, but they are more common in people under 20 years of age. Because these Parkinsons symptoms are not exclusive to the disease, other disorders with the same symptoms sometimes make it more complicated to make the diagnosis.

What Is The Prognosis And Life Expectancy For Parkinson’s Disease
The severity of Parkinson’s disease symptoms and signs vary greatly from person to person, and it is not possible to predict how quickly the disease will progress.
- Parkinson’s disease itself is not a fatal disease, and the average life expectancy is similar to that of people without the disease.
- Secondary complications, such as pneumonia, falling-related injuries, and choking can lead to death.
- Many treatment options can reduce some of the symptoms and prolong the quality of life.
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.

Why Is Distinguishing Young
Socially, people who are affected by PD at a younger age experience the disease differently they may be at a different stage of their career and often have less time to engage in their own care. They may also have children or are planning to have children and have questions regarding passing on PD genes.
Medically, doctors tailor treatment when it is a younger person with PD. The younger you are, the more likely the disease is genetic. Your care team may offer genetic testing or counseling. Younger brains also have a higher neuroplasticity potential which allows the brain to handle and respond to disease and therapy differently.
A Family With Parkinson Disease Essential Tremor Bell Palsy And Parkin Mutations
Archives of Neurology 2007, 64 : 421-4
BACKGROUND: Mutations in the parkin gene cause autosomal recessive early-onset Parkinson disease . The A265G variant in the HS1 binding protein 3 gene is common in essential tremor .
OBJECTIVE: To investigate the presence of mutations in the parkin gene and the A265G variant in the HS1BP3 gene in a Mexican family with EOPD, ET, and Bell palsy.
DESIGN: Direct sequencing, semiquantitative polymerase chain reaction, and reverse transcription-polymerase chain reaction were performed in the 14 members of this family.
SETTING: Mexican family. Patients Two patients with EOPD were analyzed.
RESULTS: Compound heterozygous mutations in the parkin gene were identified in 2 patients with EOPD, characterized by beneficial response to levodopa, relatively slow progression, and motor complications. Although heterozygous EX 3_6 del and homozygous EX 5 del mutations in the parkin gene have been previously described, to our knowledge, this is the first report of these mutations in compound heterozygotes. Seven heterozygous A265G variants in the HS1BP3 gene were found in this pedigree, but they did not cosegregate with ET, Parkinson disease, or Bell palsy, supporting the conclusion that this variant is not associated with ET.

What Are The Complications Of Parkinson Disease
Parkinson disease causes physical symptoms at first. Problems with cognitive function, including forgetfulness and trouble with concentration, may arise later. As the disease gets worse with time, many people develop dementia. This can cause profound memory loss and makes it hard to maintain relationships.
Parkinson disease dementia can cause problems with:
- Speaking and communicating with others
- Problem solving
- Paying attention
If you have Parkinson disease and dementia, in time, you likely won’t be able to live by yourself. Dementia affects your ability to care of yourself, even if you can still physically do daily tasks.
Experts don’t understand how or why dementia often occurs with Parkinson disease. Its clear, though, that dementia and problems with cognitive function are linked to changes in the brain that cause problems with movement. As with Parkinson disease, dementia occurs when nerve cells degenerate, leading to chemical changes in the brain. Parkinson disease dementia may be treated with medicines also used to treat Alzheimer’s disease, another type of dementia.
What Are The Later Secondary Signs And Symptoms Of Parkinson’s Disease
While the main symptoms of Parkinson’s disease are movement-related, progressive loss of muscle control and continued damage to the brain can lead to secondary symptoms. These secondary symptoms vary in severity, and not everyone with Parkinson’s will experience all of them, and may include:

How Is Parkinsons Disease Diagnosed
Diagnosing Parkinsons disease is sometimes difficult, since early symptoms can mimic other disorders and there are no specific blood or other laboratory tests to diagnose the disease. Imaging tests, such as CT or MRI scans, may be used to rule out other disorders that cause similar symptoms.
To diagnose Parkinsons disease, you will be asked about your medical history and family history of neurologic disorders as well as your current symptoms, medications and possible exposure to toxins. Your doctor will look for signs of tremor and muscle rigidity, watch you walk, check your posture and coordination and look for slowness of movement.
If you think you may have Parkinsons disease, you should probably see a neurologist, preferably a movement disorders-trained neurologist. The treatment decisions made early in the illness can affect the long-term success of the treatment.
Study Design And Participants
All the clinical data and 123I-FP-CIT SPECT images used in this study were downloaded from the PPMI database. The PPMI is an ongoing longitudinal, international, multicentre, observational clinical study of patients with early Parkinsons disease aimed at identifying disease biomarkers . The study ascertains patients with a clinical disease duration of < 2 years who periodically undergo clinical motor evaluation and imaging with 123I-FP-CIT SPECT. The diagnosis of Parkinsons disease had to be supported by an in vivo evidence of nigrostriatal dopaminergic dysfunction all patients with tremor and normal scans were followed up as a separate group . The full list of inclusion and exclusion criteria can be found in the PPMI study protocol, available online at .
Our analysis was focused on the period from baseline to the 2-year follow-up, as not enough patients had completed longer follow-ups. We therefore downloaded clinical motor assessments and 123I-FP-CIT SPECT images at both baseline and 2-year follow-up from the PPMI database in August 2015. For patients who did not have a 2-year assessment the previous or successive one was used.

What Causes Parkinson Disease
Parkinson disease arises from decreased dopamine production in the brain. The absence of dopamine makes it hard for the brain to coordinate muscle movements. Low dopamine also contributes to mood and cognitive problems later in the course of the disease. Experts don’t know what triggers the development of Parkinson disease most of the time. Early onset Parkinson disease is often inherited and is the result of certain gene defects.
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 Parkinsons. 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.

Complications Related To Parkinsons Can Affect Survival
Claudia Chaves, MD, is board-certified in cerebrovascular disease and neurology with a subspecialty certification in vascular neurology. She is an associate professor of neurology at Tufts Medical School and medical director of the Lahey Clinic Multiple Sclerosis Center in Lexington, Massachusetts.
Parkinsons is a common neurodegenerative disease, and although it is not fatal, research suggests it may influence life expectancy.
A 2012 study in Archives of Neurology examined the six-year survival of nearly 140,000 Medicare beneficiaries with Parkinsons disease in the United States. During the six-year period, 64% of the participants with Parkinsons disease passed away.
The risk of death of those with Parkinsons was then compared to Medicare beneficiaries who did not have Parkinsons or any other common diseases, including:
When controlling for variables like age, race, and gender, the six-year risk of death among people with Parkinsons was found to be nearly four times greater than those Medicare beneficiaries without the disease or other common diseases.
At the same time, the rate of death among those with Parkinsons disease was similar to those with hip fracture, Alzheimers dementia, or a recent heart attackalthough it was higher than those who had been newly diagnosed with either colorectal cancer, stroke, ischemic heart disease, or chronic obstructive pulmonary disease.

How Does Exercise Change The Brain
Exercise affects how efficiently dopamine is used in the brain it does not produce more of the hormone dopamine. According to the Parkinsons Foundation, exercise improves this efficiency by modifying the areas of the brain where dopamine signals are received.
When dopamine travels through the brain, it connects to two brain cells through a space called the synapse. For one cell to close off the signal of dopamine to send it to the next cell, a protein complex known as the dopamine transporter has to pick it up. Studies have shown that people who exercise more have less of the dopamine transporter, allowing the dopamine to stay in the synapse longer and send a longer signal.
Dr. Joseph Jankovic, neurologist at Baylor St. Lukes Medical Center, has been a principal investigator in over 100 clinical trials for treatments of Parkinsons disease. He is also the founder and director of the Parkinson’s Disease Center and Movement Disorders Clinic, which has been recognized as a Center of Excellence by the National Parkinsons Foundation.
People who exercise also have increased connectivity within the brain, and they have less age-related degeneration of the brain. All of these factors support a notion that the brain benefits from long-term exercise, and this has been specifically shown in patients with Parkinsons disease.

How To Recognize Early Signs Of Parkinsons Disease
Parkinsons disease is a progressive neurological disease that mainly affects people over 60 years of age. Before we get into the signs and symptoms that can hint at the diagnosis of PD, lets review the areas of the brain that are affected by this nerve-degenerating disease.
The brain has multiple overlapping systems involved in the initiation and execution of smooth, controlled, and coordinated movement. These systems influence and modify motor commands from the primary motor cortex.
There are six major regions of the brain that are involved in modifying movement:
These regions of the brain influence the final common pathway of motor commandthe pyramidal system. The pyramidal system consists of the primary motor cortex, the corticospinal tracts, and the corticobulbar tracts.
Environmental Factors And Exposures
Exposure to pesticides and a history of head injury have each been linked with PD, but the risks are modest. Never drinking caffeinated beverages is also associated with small increases in risk of developing PD.
Low concentrations of urate in the blood is associated with an increased risk of PD.
Different medical drugs have been implicated in cases of parkinsonism. Drug-induced parkinsonism is normally reversible by stopping the offending agent. Drugs include:
