Causes Of Early Onset Parkinsons Disease
Its unclear exactly what causes Parkinsons at any age. Genetic factors, environmental factors, or some combination of the two may play a role. This condition occurs when cells are lost in the part of the brain that produces dopamine. Dopamine is responsible for sending brain signals that control movement.
Certain genes are associated with early onset Parkinsons.
According to the National Parkinson Foundation, studies show that 65 percent of people with Parkinsons who experience onset before age 20 may do so because of a genetic mutation. This organization also suggests this mutation affects 32 percent of people who experience onset between age 20 and 30.
Environmental causes of the condition may include exposure to chemical toxins such as certain insecticides, fungicides, and herbicides.
The U.S. Department of Veterans Affairs recognizes Parkinsons as a disease caused by exposure to Agent Orange. Agent Orange is a synthetic chemical herbicide that was used to spray vegetation and trees during the Vietnam War.
You may have a higher risk of developing Parkinsons if you:
- are a man
What Treatments Are Available
Many Parkinson’s 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. Parkinson’s 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 Parkinson’s. 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.
Surgery And Deep Brain Stimulation
Deep brain stimulation is a treatment for Parkinsonâs disease that uses an implantable pacemaker-like device to deliver electrical pulses to parts of the brain involved in movement. The DBS system consists of leads precisely inserted into a specific brain target, the neurostimulator implanted in the chest, and extension wires that connect the leads to the neurostimulator. Though implantation of the system requires a neurosurgical procedure, the treatment itself consists of long-term electrical stimulation. Advantages of DBS include its ability to reduce the high doses of medications , its adjustability , and its reversibility DBS was approved by the Food and Drug Administration as a treatment for PD in 2002 and according to Medtronic , more than 80,000 patients have undergone DBS surgery worldwide.
Typical candidates are those who have motor fluctuations or periods of âoffâ time with troublesome symptoms alternating with periods of âonâ time with good symptom control, and also with possible periods of excessive movement .
Not all patients with Parkinsonâs disease are good candidates for treatment with DBS. Approximately 10â20% of patients considered for possible treatment with DBS include those:

Is There A Test To Diagnose Pd Dementia
There is no single test for PDD. The diagnosis is made clinically. If you or someone you spend time with notices cognitive changes, it is important to discuss them with your care team. If you dont have a care team in place, its important to find a specialist or physician familiar with dementia or geriatric medicine. Call the Parkinson’s Foundation Helpline 1-800-4PD-INFO for a referral.
What Are The Ways To Prevent Parkinsons Disease In A Patient
According to the research done so far, doctors and scientists believe that Parkinsons disease is triggered through a combination of genetic factors and exposure to factors like trauma and certain kinds of toxins and illness. Thus, the Parkinsons disease cannot be prevented as of now since proper etiology is yet to be discovered.

What Is The Best Way To Communicate With A Person With Pdd
PD-related mood and motor changes can impact communication cognitive changes and Parkinsons disease dementia can further these difficulties.
- It is not usually helpful to try to reason or argue with someone experiencing a hallucination or delusion. Stay calm and be patient. If the person is frightened by the hallucination or delusion, try to redirect their attention to something else.
- You may find acknowledging what the person is seeing, even if you do not see it, can reduce stress.
- Speak slowly and at eye level. Communicate in simple sentences.
- Ask one question at a time and wait for an answer.
- Limit distractions. Turn off the TV or radio before asking a person with PDD to do something.
- Consider causes behind disruptive behavior: the person may be hungry, thirsty, tired, in pain, frustrated, lonely or bored.
- If the person is stuck on an idea, try agreeing with them, then changing the subject.
- Its OK to use humor to diffuse stressful situations but avoid negative humor or sarcasm these can be misunderstood.

Symptoms Of Parkinson’s Disease
The symptoms and rate of progression of Parkinsons are different among individuals. Effects of normal aging are sometimes confused for Parkinsons. It is difficult to accurately diagnose this disease because there is not a test that can accurately do it.
There are physical and non-physical symptoms that could indicate someone has Parkinsons disease:
Physical symptoms
Early stage symptoms
Parkinson’s disease occurs gradually. At first, the symptoms might not even be noticeable. Early symptoms can include feeling mild tremors or having difficulty getting out of bed or a chair. The person might start to notice that they are speaking softer than usual, or that their handwriting looks different.
Usually, it is friends or family members who are the first to notice changes in someone with early Parkinson’s. For example, they may notice that the person’s face lacks expression and animation, or that the person does not move an arm or leg normally.

Is Parkinsons Disease Inherited
Scientists have discovered gene mutations that are associated with Parkinsons disease.
There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.
Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.
Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.
Caregiving For People Living With Parkinsons
Caring for a loved one with PD can be a challenging job, especially as the disease progresses. Former caregivers of a loved one with PD suggest doing the following : Get prepared, Take care of yourself, Get help , Work to maintain a good relationship with your loved one, and Encourage the person with PD for whom you care, to stay active.
Preparing for caregiving starts with education. Reading this fact sheet is a good start. More resources are available to you in theResources section of this fact sheet. Early Parkinsonâs disease usually requires more emotional support and less hands-on care. It is a good time for family members/caregivers to educate themselves about the disease.

Causes Of Parkinson’s Disease
Parkinsons occurs when neurons in the part of the brain that control body movement become impaired or die. These neurons are responsible for creating dopamine, an important brain chemical that is vital for normal body function.
With fewer of these neurons in the brain, insufficient dopamine is created. Scientists are still not sure what exactly causes these neurons to become impaired or die.
People with Parkinsons also lose nerve endings that produce norepinephrine, the chemical messenger of the sympathetic nervous system that controls heart rate and blood pressure. This could be why fatigue and a decrease in blood pressure regularly occur with people who have Parkinsons.
While there have been cases of the disease that appear to be hereditary and can be traced to specific genetic mutations, there isnt enough evidence yet to conclusively prove it is passed down from parents to their children.
Most cases of Parkinsons occur randomly, and researchers believe a combination of genetic and environmental factors are responsible.
What If I Carry The Gene
There are ongoing clinical trials testing therapies to treat people who have Parkinson’s and carry certain gene mutations. Proving that it can be important to know which gene mutation you carry. Consult with your doctor when considering a genetic test to determine if you are eligible to participate in gene-based clinical trials.
The Parkinsons Foundation study, PD GENEration: Mapping the Future of Parkinsons Disease, is the first national study to offer genetic testing and counseling at no cost for those with a confirmed Parkinsons diagnosis. Learn more and enroll at Parkinson.org/PDGENEration.

What Raises Someone’s Risk For Parkinson’s
It’s a complex picture, but you may be more likely to get Parkinson’s based on:
Age. Since it mostly affects people 60 and older, your risk goes up as the years go by.
Family history. If your parent, brother, or sister has it, you’re a little more likely to get it.
Job. Some types of work, like farming or factory jobs, can cause you to have contact with chemicals linked to Parkinson’s.
Race. It shows up more often in white people than other groups.
Serious head injury. If you hit your head hard enough to lose consciousness or forget things as a result of it, you may be more likely to get Parkinson’s later in life.
Gender. Men get it more than women. Doctors aren’t sure why.
Where you live. People in rural areas seem to get it more often, which may be tied to chemicals used in farming.
The Genetics Of Parkinsons
A 2020 study including 1,676 people with Parkinsons in mainland China suggested that genes play a role in the development of the condition. An estimated 10 to 15 percent of people with Parkinsons have a family history of the condition.
In fact, a number of specific genes have been linked to the development of Parkinsons.
How do genetics factor into Parkinsons in some families? According to Genetics Home Reference, one possible way is through the mutation of genes responsible for producing dopamine and certain proteins essential for brain function.

Testing For Parkinsons Disease
There is no lab or imaging test that is recommended or definitive for Parkinsons disease. However, in 2011, the U.S. Food and Drug Administration approved an imaging scan called the DaTscan. This technique allows doctors to see detailed pictures of the brains dopamine system.
A DaTscan involves an injection of a small amount of a radioactive drug and a machine called a single-photon emission computed tomography scanner, similar to an MRI.
The drug binds to dopamine transmitters in the brain, showing where in the brain dopaminergic neurons are.
The results of a DaTscan cant show that you have Parkinsons, but they can help your doctor confirm a diagnosis or rule out a Parkinsons mimic.
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.

Parkinson’s Disease Diet And Nutrition
Maintaining Your Weight With Parkinson’s Disease
Malnutrition and weight maintenance is often an issue for people with Parkinson’s disease. Here are some tips to help you maintain a healthy weight.
- Weigh yourself once or twice a week, unless your doctor recommends weighing yourself often. If you are taking diuretics or steroids, such as prednisone, you should weigh yourself daily.
- If you have an unexplained weight gain or loss , contact your doctor. He or she may want to modify your food or fluid intake to help manage your condition.
- Avoid low-fat or low-calorie products. . Use whole milk, whole milk cheese, and yogurt.

Stages Of Parkinsons Disease
Neurologists usually describe the progression of Parkinsons symptoms in stages, using the system known as the Hoehn and Yahr scale. These stages are:
- Stage I Symptoms are seen on one side of the body only.
- Stage II Symptoms are seen on both sides of the body. Theres no impairment of balance.
- Stage III Balance impairment has begun. In this mild- to moderate stage of the disease, the person is still physically independent.
- Stage IV This stage is marked by severe disability, but the person is still able to walk or stand unassisted.
- Stage V The person is wheelchair-bound or bedridden unless assisted.
Help Them Feel Normal
A disease like Parkinsons can interfere with the normalcy of someones life. Because people may focus so much on the disease and its symptoms, your loved one may start to lose their sense of self. When you talk to your loved one, dont constantly remind them that they have a chronic disease. Talk about other things like their favorite new movie or book.

Causes And Risk Factors Of Parkinsons Disease
Most cases of Parkinsons disease are idiopathic, meaning the cause is unclear.
Its widely believed that a person with Parkinsons may have been genetically vulnerable to the disease, and that one or more unknown factors in the environment eventually triggered the disease.
Most of the symptoms of Parkinsons disease come from the loss of neurons in an area of your brain called the substantia nigra.
Normally, the neurons in this part of the brain make the chemical messenger dopamine, which allows communication with another area of the brain, the corpus striatum.
This communication helps produce smooth, purposeful movement. When the neurons in the substantia nigra die, the resulting loss of communication leads to the motor symptoms of Parkinsons.
Although the cause of this cell death is unknown, many researchers believe that the cells are killed by clumped proteins called Lewy bodies.
One Of The Most Difficult Neurological Disorder Symptoms Of Parkinsons
Why might this be important to families challenged by PD? Because the biggest source of conflict in families occurs when loved ones fail to recognize that a person with brain changes is not the same person who existed at an earlier time in life. Human beings greatly value continuity in personality but by expecting the person to be the same as they once were, loved ones are unfair to the person with brain insult. This person could no more return to an earlier personality state than he or she can will away tremors or rigidity. Energy expended in any way other than coming to terms with this new person is fruitless. There is actually some fascinating research in this area and it is likely to be a topic for a great deal more discussion in future blogs.
Because of the greater likelihood for executive dysfunction and dementia, personality change is easier to see among individuals with more advanced PD. Motivation is frequently affected, resulting in apathy that diminishes how actively an individual interacts with other people and with the world . Thinking or cognition changes can cause the person to process information more slowly and with less focus and concentration . A previously methodical, consistent individual often becomes increasingly chaotic in their response to their environment . One easily becomes less interested and hopeful about the future .
