Causes Of Parkinsons Disease
At present, we do not know the cause of Parkinsons disease. In most people there is no family history of Parkinsons Researchers worldwide are investigating possible causes, including:;
- environmental triggers, pesticides, toxins, chemicals
- genetic factors
- combinations of environment and genetic factors;
- head trauma.
Brain Imaging And Other Tools To Aid Diagnosis Of Parkinsons
In addition to taking a history and performing a detailed neurologic examination, physicians sometimes use brain imaging to help support a particular diagnosis. However, these studies have their limitations in the diagnosis of Parkinsons disease and are typically used only in select patients. Brain imaging is not routinely performed by neurologists or movement disorder specialists when they are considering a diagnosis, especially if the persons symptoms strongly suggest to the physician that idiopathic Parkinsons disease is the correct diagnosis.
Helping diagnose Parkinsons with DaTscan and other tests
Rather, use of imaging is most helpful when the diagnosis is uncertain, or when physicians are looking for changes in the brain that are more typical of one of several Parkinsonian syndromes and other conditions that can mimic Parkinsons. Imaging studies to evaluate Parkinsons disease and Parkinsonian syndromes include magnetic resonance imaging , which examines the structure of the brain, and DaTscan, an imaging test approved by the Food and Drug Administration to detect the dopamine function in the brain. A DaTscan may help differentiate idiopathic Parkinsons disease from certain other neurologic disorders. Most physicians offices will have access to MRI; however, DaTscan imaging may only be available at larger hospitals or medical centers.
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.

Fatigue In Parkinsons Disease
Fatigue is a common but under-recognized problem for people with Parkinsons disease . Fatigue can be defined as an unpleasant sensation of lacking energy, making the performance of routine activities, physical or mental, a strain. People with PD may experience physical fatigue, mental fatigue, or both. Fatigue in PD is not the same as the feeling you might get at the end of a hard days work. It is not necessarily something that goes away with rest. When people with PD are asked about fatigue, they use phrases such as, I feel run down, I am out of energy, I am unable to do anything, I cant get motivated.

Fatigue and Depression
There is a large overlap between fatigue and other problems in PD, especially depression and sleep disorders. People with fatigue are more likely to be depressed and people who are depressed are more likely to be fatigued, but there is nonetheless a large group of PD patients who are fatigued but not depressed. Depression in PD typically responds to antidepressant treatment, and depression-related fatigue may improve with such treatment.

Embarrassing Symptoms Of Parkinson’s Disease
Some symptoms that may occur in people with Parkinsons disease are not typical of it and so people noticing them may misunderstand them. These symptoms can be particularly embarrassing in social situations where other people witness their discomfort. They distress some people so much that they avoid company other than close friends or family. Most of these symptoms are caused by Parkinsons but some are side effects of the medicines used to treat it. All the symptoms tend to fluctuate in relation to the medication, and some people had learnt to adjust their medicine regime to minimise these effects.
Eating can cause embarrassment in several ways. Both tremor and dyskinesia affect the physical job of cutting up food and directing it into the mouth . Several people had a problem with a piece of steak or chicken that might fly off the plate as they tried to cut it up, or they had a choking fit if they unwisely took too big a piece into their mouth. Humphrey disliked eating out with friends because he tended to drop things.

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. In Essential Tremor, the hands are most commonly involved, followed by the head and then the voice. Essential Tremor can also 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.
Discuss With Your Physician
Non-motor symptoms can sometimes be difficult to recognize. Therefore, it is important to make your doctor aware of them.
One useful resource is the PD NMS Questionnaire. You can use this to record your symptoms and discuss them with your doctor.
Dr. Ron Postuma, whose research was funded by donations to the Parkinson Canada Research Program, has also developed tools to help people with Parkinsons and their physicians identify and manage non-motor 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.
Symptoms Of Parkinson’s Disease
The symptoms of Parkinson’s disease usually develop gradually and are mild at first.
There are many different symptoms associated with Parkinson’s disease. Some of the more common symptoms are described below.
However,;the order in which these develop and their severity is different for each individual.;It’s unlikely that;a person;with Parkinson’s disease would experience all or;most of these.

Parkinson’s Disease Symptoms Everyone Should Know
Parkinsons disease symptoms can include tremor and trouble with movement, along with emotional and cognitive changes.
Parkinson’s disease symptoms can vary significantly from person to person. Some people may have range of motor symptoms, like tremor, stiffness, and slow movements. Others may also experience the non-motor symptoms of Parkinson’s disease, such as anxiety, cognitive changes, and loss of smell.
It has to do with a chemical messenger known as dopamine, which plays a role in the brain’s ability to control movement, coordination, and emotional responses. In Parkinson’s disease, the brain cells that produce dopamine either stop doing their job or they die out, resulting in both motor and non-motor symptoms. ; It’s not always easy to tell if someone you care about has Parkinson’s disease. Let’s take a closer look at the symptoms of the disease and signs that someone should make an appointment with their doctor.
Exercise And Healthy Eating
Regular exercise is particularly important in helping relieve muscle stiffness, improving your mood, and relieving stress.
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.

Depression And Anxiety Are Also Early Warning Signs Of Parkinson’s How So
A: Like the other symptoms discussed here, late-onset depression and anxiety are nonmotor prodromal manifestations of the condition. It’s not that everyone who is depressed will get Parkinson’s, and the numbers are lower than they are for symptoms like anosmia and REM behavior disorder. But the link is important to explore, and we are doing more research on it all the time.
Stiffness And Slow Movement
Parkinsons disease mainly affects adults older than 60. You may feel stiff and a little slow to get going in the morning at this stage of your life. This is a completely normal development in many healthy people. The difference with PD is that the stiffness and slowness it causes dont go away as you get up and start your day.
Stiffness of the limbs and slow movement appear early on with PD. These symptoms are caused by the impairment of the neurons that control movement. A person with PD will notice jerkier motions and move in a more uncoordinated pattern than before. Eventually, a person may develop the characteristic shuffling gait.

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.
What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.

Deep Brain Stimulation For Parkinson’s: Am I A Candidate
Deep brain stimulation is not a cure, but it can relieve your symptoms from Parkinson’s disease when medications are not an option. Only you and your doctor can decide if this surgical procedure is right for you. You may be a candidate for deep brain stimulation if:
- You have idiopathic Parkinson’s disease. Patients with atypical parkinsonism are not candidates.
- You have good motor function and independence during your best “on” state when taking the drug Sinemet.
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.

How Early Can Parkinson’s Disease Be Diagnosed
A: A true determination of Parkinson’s disease is a clinical diagnosis, which means certain motor symptoms have to be present, but we now know more about some early signs of Parkinson’s disease that, while they don’t always lead to the condition, are connected.
In terms of how early we can detect, we can detect a mutation that is associated with an increased risk of Parkinson’s as early as birth. In the minority of patients who may have a known Parkinson’s-related genetic mutation , that gene could be tested for at any time in life. At the same time, that’s not diagnosing Parkinson’s; it’s just identifying the risk.
Early warning signs are what we call prodromal, or preclinical, symptoms. Prodromal symptoms are an early warning sign that someone might get Parkinson’s disease. Though some of these symptoms have a very high probability of signaling future Parkinson’s, having one or more of them is still not a 100 percent probability. Some prodromal symptoms are loss of sense of smell, REM behavior disorder, anxiety or depression, and constipation.
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.

How Is Parkinsons Disease Treated
There is no cure for Parkinsons disease. However, medications and other treatments can help relieve some of your symptoms. Exercise can help your Parkinsons symptoms significantly. In addition, physical therapy, occupational therapy and speech-language therapy can help with walking and balance problems, eating and swallowing challenges and speech problems. Surgery is an option for some patients.

The mask that is the expressionless face, typical of many people with Parkinsons, probably distresses the people who have to live with it more than it embarrasses the person who has it. It tends to be the position the face falls into when not actively doing something else. Lack of facial expression can be hard for the family.
