How Does Parkinsons Disease Affect The Brain
The part of the brain that is affected is called the basal ganglia, which functions like the autopilot of your brain, facilitating subconscious movements. Because PD causes the brain cells in this deep circuitry to deteriorate, patients natural movements become slow and stiff. Many patients describe feeling as if they had aged overnight.
What Are The Pitfalls Of Datscan
DaTscan will appear abnormal in any disease in which there is a loss of dopamine nerve endings in the striatum. Therefore, Parkinson-plus syndromes, discussed in a prior blog, such as Progressive supranuclear palsy , Corticobasal ganglionic degeneration and Multiple system atrophy all typically demonstrate abnormal DaTscans. DaTscan therefore cannot be used to distinguish between these syndromes.
Every medical test has a false positive and a false negative rate. This means, that it is inevitable that in a certain percentage of people who have PD, the DaTscan will be read as normal and in a certain percentage of people without PD, the DaTscan will be read as abnormal. Results of any medical test that is performed, must therefore be considered within the entire clinical context.
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.

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:
- Decreased facial expressions: You may not smile or blink as often as the disease worsens; your face lacks expression.
- 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.
What You Can Expect
Parkinson does follow a broad pattern. While it moves at different paces for different people, changes tend to come on slowly. Symptoms usually get worse over time, and new ones probably will pop up along the way.
Parkinsonâs doesnât always affect how long you live. But it can change your quality of life in a major way. After about 10 years, most people will have at least one major issue, like dementia or a physical disability.
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 .
What Are The Diagnostic Criteria For Parkinsons
Doctors diagnose Parkinsons clinically based on your symptoms and medical history.
No individual test can be used to diagnose Parkinsons. Many other neurogenerative conditions can lead to similar symptoms, so your doctor may use a blood test, brain scans, or other tests to rule out other conditions.
Testing For Parkinsons Disease
There is no lab or imaging test that is recommended or definitive forParkinsons disease. However, in 2011, the U.S. Food and DrugAdministration approved an imaging scan called the DaTscan. Thistechnique allows doctors to see detailed pictures of the brainsdopamine system.
A DaTscan involves an injection of a small amount of a radioactive drugand 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 inthe brain dopaminergic neurons are.
The results of a DaTscan cant show that you have Parkinsons, but theycan help your doctor confirm a diagnosis or rule out a Parkinsonsmimic.
What Are The Symptoms Of End
Stage four for Parkinsons disease is often called advanced Parkinsons disease because people in this stage experience severe and incapacitating symptoms. This is when medication doesnt help as much and serious disabilities set in.
Theres an increased severity in:
- How you speak a softer voice that trails off.
- Falling and trouble with balance and coordination.
- Freezing a sudden, but temporary inability to move, when you start to walk or change direction.
- Moving without assistance or a wheelchair.
- Other symptoms such as constipation, depression, loss of smell, low blood pressure when going to stand up, pain, and sleep issues.
Many times someone with advanced PD cant live on their own and needs help with daily tasks.
Stage five is the final stage of Parkinsons, and assistance will be needed in all areas of daily life as motor skills are seriously impaired. You may:
- Experience stiffness in your legs. It may make it impossible to walk or stand without help.
- Need a wheelchair at all times or are bedridden.
- Need round-the-clock nursing care for all activities.
- Experience hallucinations and delusions.
As Parkinsons disease progresses into these advanced stages, its symptoms can often become increasingly difficult to manage. Whether you or your loved one with end-stage Parkinsons lives at home, in an assisted living facility or a nursing home, hospice services can optimize your quality of life and that of your family members as well.
What Are The Different Stages Of Parkinsons Disease
Each person with Parkinsons disease experiences symptoms in in their own unique way. Not everyone experiences all symptoms of Parkinsons disease. You may not experience symptoms in the same order as others. Some people may have mild symptoms; others may have intense symptoms. How quickly symptoms worsen also varies from individual to individual and is difficult to impossible to predict at the outset.
In general, the disease progresses from early stage to mid-stage to mid-late-stage to advanced stage. This is what typically occurs during each of these stages:
Early stage
Early symptoms of Parkinsons disease are usually mild and typically occur slowly and do not interfere with daily activities. Sometimes early symptoms are not easy to detect or you may think early symptoms are simply normal signs of aging. You may have fatigue or a general sense of uneasiness. You may feel a slight tremor or have difficulty standing.
Often, a family member or friend notices some of the subtle signs before you do. They may notice things like body stiffness or lack of normal movement slow or small handwriting, lack of expression in your face, or difficulty getting out of a chair.
Mid stage
Mid-late stage
Standing and walking are becoming more difficult and may require assistance with a walker. You may need full time help to continue to live at home.
Advanced stage
What Can You Do If You Have Pd
- Work with your doctor to create a plan to stay healthy. This might include the following:
- A referral to a neurologist, a doctor who specializes in the brain
- Care from an occupational therapist, physical therapist or speech therapist
- Meeting with a medical social worker to talk about how Parkinson’s will affect your life

How Can I Try To Get An Early Diagnosis
Theres still debate among medical professionals on how long non-motor symptoms may appear before an individual has noticeable changes in their movement. Its thought that they could appear years to decades beforehand.
But a formal Parkinsons diagnosis requires the symptom slowness of movement. In the time before this symptom appears, your doctor cant make a Parkinsons diagnosis, but they may alert you that youre at a high risk of developing Parkinsons in the future if these or other symptoms appear at any point.
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.
New Diagnostic Standards For Parkinsons
Until recently, the gold-standard checklist for diagnosis came from theU.K.s Parkinsons Disease Society Brain Bank. It was a checklist thatdoctors followed to determine if the symptoms they saw fit the disease.But thats now considered outdated. Recently, new criteria from theInternational Parkinson and Movement Disorder Society have come intouse. This list reflects the most current understanding of thecondition. It allows doctors to reach a more accurate diagnosis sopatients can begin treatment at earlier stages.
Deep Brain Stimulation Surgery For Parkinson’s Disease At Ucla
If you’ve been diagnosed with Parkinson’s, your doctor will first prescribe medication. There are many drugs available that improve symptoms, but they have many side effects, including nausea, hallucinations and impulsive behavior. Some patients respond well to medications for years before seeing side effects. In these patients, the drugs may start to wear off quickly, or they may become extremely sensitive to the drugs and experience too much movement
Deep brain stimulation is a surgical option available to patients who are intolerant of medications or who experience serious side effects. This procedure involves implanting electrodes, or wires, deep inside the brain to change irregular brain activity. As a result, it improves motor function in patients with Parkinson’s disease. It is used more often to treat Parkinson’s disease than any other movement disorder.
How Does Parkinson’s Affect The Body
The telltale symptoms all have to do with the way you move. You usually notice problems like:
Rigid muscles. It can happen on just about any part of your body. Doctors sometimes mistake early Parkinson’s for arthritis.
Slow movements. You may find that even simple acts, like buttoning a shirt, take much longer than usual.
Tremors. Your hands, arms, legs, lips, jaw, or tongue are shaky when you’re not using them.
Walking and balance problems. You may notice your arms aren’t swinging as freely when you walk. Or you can’t take long steps, so you have to shuffle instead.
Parkinson’s can also cause a range of other issues, from depression to bladder problems to acting out dreams. It may be a while before abnormal movements start.
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.
Living With Parkinson’s Disease
As Parkinson’s develops, a person who has it may slow down and won’t be able to move or talk quickly. Sometimes, speech therapy and occupational therapy are needed. This may sound silly, but someone who has Parkinson’s disease may need to learn how to fall down safely.
If getting dressed is hard for a person with Parkinson’s, clothing with Velcro and elastic can be easier to use than buttons and zippers. The person also might need to have railings installed around the house to prevent falls.
If you know someone who has Parkinson’s disease, you can help by being a good friend.
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 peson, 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.
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 Parkinson’s
Doctors aren’t sure why all those brain cells start dying. They think it’s a mix of your genes and something in the environment, but the reason is not straightforward.
Someone could have a change in a gene tied to Parkinson’s, but never get the disease. That happens a lot. And a bunch of people could work side by side in a place with chemicals linked to Parkinson’s, but only a few of them end up with it.
It’s a complex puzzle, and scientists are still trying to put all the pieces together.
What Tests Might I Have
Your doctor may want to start by testing your blood or doing a brain scan to rule out other conditions.
People who have Parkinsonâs disease donât make enough of a brain chemical called dopamine, which helps you move. If those first tests donât show a reason for your symptoms, your doctor may ask you to try a medication called carbidopa-levodopa, which your brain can turn into dopamine. If your symptoms get much better after you start the drug, your doctor probably will tell you that you have Parkinsonâs disease.
If the medication doesnât work for you and thereâs no other explanation for your issues, your doctor might suggest an imaging test called a DaTscan. This uses a small amount of a radioactive drug and a special scanner, called a single photon emission computed tomography scanner, to see how much dopamine is in your brain. This test can’t tell you for sure that you have Parkinson’s disease, but it can give your doctor more information to work with.
It can take a long time for some people to get a diagnosis. You may need to see your neurologist regularly so they can keep an eye on your symptoms and eventually figure out whatâs behind them.
What Is A Datscan
A DaTscan is an imaging drug, also called Ioflupane I 123 or phenyltropane, that acts as a radioactive tracer for dopamine transporters within the brain. This drug was approved by the FDA in 2011. It may help distinguish the diagnosis of essential tremor from Parkinson’s syndromes, like Parkinsons disease or Parkinsons disease dementia.
The drug is administered during the SPECT scan. This scanning technique gathers images of a particular area in the brain called the striatum, a cluster of neurons in the subcortical basal ganglia of the forebrain. The striatum helps facilitate the transportation of dopamine.
DaTscan is injected into the patients bloodstream and eventually circulates to the brain. The tracer attaches itself to a molecule found on dopamine neurons in the striatum called the dopamine transporter . The patient then undergoes a SPECT scan which will produce an image of the dopaminergic neuron terminals that remain available in the striatum.
In patients with a diagnosis of Parkinsons disease, or parkinsonism , this area of the brain will show dark. This indicates the loss of dopamine-containing nerve cells within the brain, a hallmark of the disease.
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 .
Medical History And Physical Exam
The process of diagnosing Parkinsons usually begins with the neurologist evaluating your medical history and performing a physical exam. For a formal diagnosis to be made, you need to have a general slowness of movement with either a resting tremor or rigidity.
During the physical exam, your doctor will have you perform a series of tests to monitor your movement. An example of a test they might use is a finger tap, where they measure how many times you can tap your finger in 10 to 15 seconds.
They will also look for signs that you may have another condition. A group of movement disorders collectively called parkinsonisms can produce symptoms that are indistinguishable from those of Parkinsons but are not the same. Usually, additional tests are needed to rule out these conditions as well.
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 .
Blood Tests And Spinal Fluid Tests
A blood test or spinal fluid test cant be used to diagnose Parkinsons. But they can be used to search for certain proteins that indicate you may have another neurodegenerative condition with similar symptoms.
The presence of elevated levels of a nerve protein called neurofilament light chain protein may indicate that you have another movement disorder, such as:
- multiple system atrophy
- corticobasal degeneration
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.
What Happens If My Claim Was Denied
Unfortunately, the VA sometimes makes mistakes when looking at a Veterans VA disability claim. This actually happens quite often, and it is the main reason we help Veterans appeal unfavorable VA decisions. While it may be disheartening to see your VA claim denied, that doesnt mean the fight is over.
The next step in the VA claims process is an appeal. You can appeal the VAs denial to grant service connection. This is when the attorneys at Berry Law step in. We can work on your claim to figure out why the claim was denied, what evidence we need to submit to get it approved, and which lane is best suited for your appeal.
Who Gets Parkinsons Disease
Parkinsonâs disease, documented in 1817 by physician James Parkinson, is the second most common neurodegenerative disease after Alzheimerâs disease. Estimates regarding the number of people in the United States with Parkinsonâs range from 500,000 to 1,500,000, with 50,000 to 60,000 new cases reported annually. No objective test for Parkinsonâs disease exists, so the misdiagnosis rate can be high, especially when a professional who doesnât regularly work with the disease makes the diagnosis.
