Theories About What Causes Parkinsons
The cause of Parkinsons disease is still unknown, although there is some evidence for the role of genetics, environmental factors, or a combination of both. It is also possible that there may be more than one cause of the disease. Scientists generally believe that both genetics and environment interact to cause Parkinsons disease in most people who have it.
Currently, there is an enormous amount of research directed at producing more answers about what causes Parkinsons disease and how it might be prevented or cured. When physicians diagnose Parkinsons, they often describe it as idiopathic . This simply means that the cause of the;disease is not known.
Parkinsons Disease Symptoms Of Dementia
Up to one-third of people living with Parkinson’s disease experience dementia, according to the Parkinson’s Disease Foundation. Problems with dementia may include trouble with memory, attention span, and what is called executive function the process of making decisions, organizing, managing time, and setting priorities.

Problems With Balance Or Walking
Bradykinesia can also contribute to increasing instability, walking difficulties and changes in gait. An early symptom of this is a decrease in the natural swing of one or both arms when walking. As things progress, the steps you take may become slower and smaller, and you may start shuffling your feet.
Some people with Parkinsons disease may also experience freezing episodes where it can feel like their feet are stuck in place, which can increase the risk of falling.

Does My Dog Have Parkinsons Disease
So, how do you tell if your dog has Parkinsons disease?
Weve already discussed head shaking and tremors, but there are other things that you need to understand and look out for.
Here are some symptoms that can point to canine Parkinsons disease:
- Difficulty keeping their balance due to poor muscle and joint control, including stumbling or an uneven gait.
- Stiffness or inflexibility such as struggling to get up or remaining in the same position without looking comfortable.
- Head shaking and involuntary tremors, which are easiest to spot when they occur in one leg. Note that many dogs have whats called hypnic jerks, which cause tremors in their sleep. This is normal and can happen to dogs of all breeds and ages.
- Poor balance. If your dog develops a drunk walk, this could indicate neurological damage. Parkinsons disease often causes dogs to lose their balance while walking or standing up from a lying or sitting position.
- Anxiety and depression. If your dogs behavior and life outlook suddenly changed, it could be a result of physical conditions such as those caused by Parkinsons. If your dog no longer feels like socializing and loses their appetite, this could signal anxiety and depression.
Its also important to understand that other diseases may have similar symptoms to canine Parkinsons.
You may feel silly watching your dog, waiting for every twitch or irregular movement.
However, its important to understand what other conditions can cause similar symptoms.

What Causes Parkinson’s Disease
Parkinson’s disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine. When the neurons die or become impaired, they produce less dopamine, which causes the movement problems of Parkinson’s. Scientists still do not know what causes cells that produce dopamine to die.
People with Parkinson’s also lose the nerve endings that produce norepinephrine, the main chemical messenger of the sympathetic nervous system, which controls many functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain some of the non-movement features of Parkinson’s, such as fatigue, irregular blood pressure, decreased movement of food through the digestive tract, and sudden drop in blood pressure when a person stands up from a sitting or lying-down position.
Many brain cells of people with Parkinson’s contain Lewy bodies, unusual clumps of the protein alpha-synuclein. Scientists are trying to better understand the normal and abnormal functions of alpha-synuclein and its relationship to genetic mutations that impact Parkinsons disease and Lewy body dementia.
Parkinson’s Surgery: Deep Brain Stimulation
Another treatment method, usually attempted as effectiveness of medical treatments for Parkinson’s disease wane, is termed deep brain stimulation. The technique involves surgery to implant electrodes deep into the brain in the globus pallidus, thalamus, or the subthalamic nucleus areas. Then electric impulses that stimulate the brain tissue to help overcome tremors, rigidity, and slow movements are given. Impulses are generated by a battery. This surgery is not for every Parkinson’s disease patient; it is done on patients that meet certain criteria. Also, the surgery does not stop other symptoms and does not end the progression of the disease.

What Is Niehs Doing
NIEHS supports diverse research, involving experts from many disciplines, to uncover what may cause or help prevent Parkinsons disease. Varied methods are important because no one can predict which paths of study will provide major breakthroughs. Basic research on Parkinson’s will continue to help us advance our understanding of the disease. Highlights from NIEHS research are described below, grouped by environmental factors that may affect Parkinsons and by research approaches.
Mounting evidence, from animal and human studies, suggests that exposure to certain types of pesticides can increase a persons risk of developing Parkinson’s disease.
Some people are more vulnerable to the harmful effects of pesticides because of their age or genetic makeup.
- Many studies identified genetic variations that provide insight into why certain people appear to be at higher risk of developing Parkinsons.
- Using data from the NIEHS-conducted Agricultural Health Study, researchers found that Parkinson’s risk from paraquat use was particularly high in people with a particular variant of a gene known as GSTT1.5
- Similarly, other research has indicated that people with lower levels of the PON1 gene, which is important for the metabolism of organophosphate pesticides, showed faster progression of the disease.6
Diet and Lifestyle
Some of the risk factors and premotor symptoms that may be involved in Parkinson’s.
What Is The Treatment For Parkinson’s Disease
There is currently no treatment to cure Parkinson’s disease. Several therapies are available to delay the onset of motor symptoms and to ameliorate motor symptoms. All of these therapies are designed to increase the amount of dopamine in the brain either by replacing dopamine, mimicking dopamine, or prolonging the effect of dopamine by inhibiting its breakdown. Studies have shown that early therapy in the non-motor stage can delay the onset of motor symptoms, thereby extending quality of life.
The most effective therapy for Parkinson’s disease is levodopa , which is converted to dopamine in the brain. However, because long-term treatment with levodopa can lead to unpleasant side effects , its use is often delayed until motor impairment is more severe. Levodopa is frequently prescribed together with carbidopa , which prevents levodopa from being broken down before it reaches the brain. Co-treatment with carbidopa allows for a lower levodopa dose, thereby reducing side effects.
In earlier stages of Parkinson’s disease, substances that mimic the action of dopamine , and substances that reduce the breakdown of dopamine inhibitors) can be very efficacious in relieving motor symptoms. Unpleasant side effects of these preparations are quite common, including swelling caused by fluid accumulation in body tissues, drowsiness, constipation, dizziness, hallucinations, and nausea.

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.

The 5 Stages Of Parkinsons Disease
Getting older is underrated by most. Its a joyful experience to sit back, relax and watch the people in your life grow up, have kids of their own and flourish. Age can be a beautiful thing, even as our bodies begin to slow down. We spoke with David Shprecher, DO, movement disorders director at Banner Sun Health Research Institute;about a well-known illness which afflicts as many as 2% of people older than 65, Parkinsons Disease.
Exercise And Healthy Eating
Regular exercise is particularly important in helping relieve muscle stiffness, improving your mood, and relieving stress.
There are many activities you can do to help keep yourself fit, ranging from more active sports like tennis and cycling, to less strenuous activities such as walking, gardening and yoga.
You should also try to eat a balanced diet containing all the food groups to give your body the nutrition it needs to stay healthy.

How Is Parkinson’s Disease Treated
If a doctor thinks a person has Parkinson’s disease, there’s reason for hope. Medicine can be used to eliminate or improve the symptoms, like the body tremors. And some experts think that a cure may be found soon.
For now, a medicine called levodopa is often given to people who have Parkinson’s disease. Called “L-dopa,” this medicine increases the amount of dopamine in the body and has been shown to improve a person’s ability to walk and move around. Other drugs also help decrease and manage the symptoms by affecting dopamine levels. In some cases, surgery may be needed to treat it. The person would get anesthesia, a special kind of medicine to prevent pain during the operation.
What Are The Symptoms Of Parkinsons Disease
Symptoms of Parkinsons disease and the rate of decline vary widely from person to person. The most common symptoms include:
Other symptoms include:
- Speech/vocal changes: Speech may be quick, become slurred or be soft in tone. You may hesitate before speaking. The pitch of your voice may become unchanged .
- Handwriting changes: You handwriting may become smaller and more difficult to read.
- Depression and anxiety.
- Sleeping disturbances including disrupted sleep, acting out your dreams, and restless leg syndrome.
- Pain, lack of interest , fatigue, change in weight, vision changes.
- Low blood pressure.

Is Parkinsons Disease Fatal
Parkinsons disease itself doesnt cause death. However, symptoms related to Parkinsons can be fatal. For example, injuries that occur because of a fall or problems associated with dementia can be fatal.
Some people with Parkinsons experience difficulty swallowing. This can lead to aspiration pneumonia. This condition is caused when foods, or other foreign objects, are inhaled into the lungs.
Do People Actually Lose Their Sense Of Smell With Parkinson’s
A: Yes. It’s a condition called anosmia, and if you have it with no other disease , you have at least a 50 percent chance of developing Parkinson’s disease in the next five to 10 years. What happens is that alpha-synuclein, the protein that clumps in the part of the brain that regulates dopamine and leads to Parkinson’s disease, also aggregates in the olfactory bulb, the part of the brain responsible for your sense of smell. This happens well before the protein accumulations cause motor symptoms.

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 Parkinson’s. 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.
Parkinsons Disease Is A Progressive Disorder
Parkinsons Disease is a slowly progressive neurodegenerative disorder that primarily affects movement and, in some cases, cognition. Individuals with PD may have a slightly shorter life span compared to healthy individuals of the same age group. According to the Michael J. Fox Foundation for Parkinsons Research, patients usually begin developing Parkinsons symptoms around age 60. Many people with PD live between 10 and 20 years after being diagnosed. However, a patients age and general health status factor into the accuracy of this estimate.
While there is no cure for Parkinsons disease, many patients are only mildly affected and need no treatment for several years after their initial diagnosis. However, PD is both chronic, meaning it persists over a long period of time, and progressive, meaning its symptoms grow worse over time. This progression occurs more quickly in some people than in others.
Pharmaceutical and surgical interventions can help manage some of the symptoms, like bradykinesia , rigidity or tremor , but not much can be done to slow the overall progression of the disease. Over time, shaking, which affects most PD patients, may begin to interfere with daily activities and ones quality of life.

The causes and symptoms of Parkinsons disease can vary from person to person. While there is no cure, there are medications and treatments to help manage the condition.
Parkinsons disease is a movement disorder that happens when nerve cells in a certain part of the brain are no longer making the chemical;dopamine.
The condition is also sometimes known as paralysis agitans or shaking palsy.
The Parkinsons Foundation estimates that 60,000 Americans are diagnosed with Parkinsons every year. However, the true number of people who develop the disease may be much higher.
Foster A Good Relationship
Lastly, maintaining your relationship and communication with the person with Parkinsonâs can be the most challenging and rewarding aspect of caregiving. As Parkinsonâs disease progresses, the roles change and the person with Parkinsonâs may go from being an independent head of the household to a very dependent person requiring a significant level of care. However, research shows that despite high levels of strain, caregivers with good quality relationships have reduced depression and better physical health. Remember, as a caregiver your service to your loved one is beyond measure in terms of love, depth of care, and concern.

The Causes Of Parkinsons Disease
Parkinson’s disease is caused by the degeneration of a small part of the brain called the substantia nigra. As brain cells in the substantia nigra die, the brain becomes deprived of the chemical dopamine.
Dopamine, a neurotransmitter, enables brain cells involved in movement control to communicate. Reduced levels of dopamine lead to the symptoms of Parkinson’s disease. According to the National Parkinson Foundation, 80% of dopamine-producing cells are lost even before the motor symptoms of Parkinson’s disease appear.2
As dopamine continues to be lost, Parkinson’s disease often becomes increasingly disabling over time. If you suffer from Parkinson’s disease, you may have trouble performing daily activities such as rising from a chair or moving across a room. As the disease progresses, some people need to use a wheelchair or may become bedridden.
