How Does Parkinsons Affect The Body

Dr. James Beck – How does Parkinson’s disease affect the brain?

Parkinsons Disease has a big physical impact on the body, as most of the side effects and symptoms are physical. Physical impacts on the body includes:

  • Slowing of the body
  • A tremor that is often apparent when the body is at rest
  • Stiffness of a limb or the body as a whole
  • Moving at a much slower
  • Trouble walking or mobility
  • Difficulty keeping ones balance
  • Loss of coordination & balance problems
  • Loss of ability to express emotions through facial expressions
  • Difficulty controlling movement throughout the body
  • Sudden drops in blood pressure

These physical side effects of this disease can heavily impact an individuals quality of life, as well as their ability to live the same type of life that they did before their diagnosis. Technically speaking, Parkinsons will have a huge impact on an individuals physical well-being, as most of the symptoms and side effects directly impact their way of life. Parkinsons can also worsen over time for some individuals, causing their physical wellness to suffer greatly. Parkinsons can cause individuals to lose their ability to walk, sit or stand as they used to. This will impact their overall bone and muscle mass, giving their body a greater chance of deterioration over time.

What Treatments Are Available

Many Parkinsons 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. Parkinsons 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 Parkinsons. 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.

The Substantia Nigra And Movement

The reason that Parkinsons causes movement symptoms is that the substantia nigra makes up part of the circuitry, called the basal ganglia, that the brain uses to turn thought about movement into action.

The structures of the basal ganglia.

The substantia nigra is the master regulator of the circuit, it mainly communicates using the chemical dopamine, but other chemical transmitters are also used to communicate between other areas of the basal ganglia.

The balance of signals being sent between these structures allows us to control movement. But as Parkinsons progresses, and the dopamine-producing brain cells in the substantia nigra are lost, movement symptoms appear. Without enough dopamine, it becomes harder to start and maintain movements, which leads to symptoms such as slowness of movement, rigidity and freezing. And an imbalance of signals in the basal ganglia means people with Parkinsons can experience what is known as a resting tremor.

But while this is the description of Parkinsons you may find in most textbooks, it is now recognised that changes are not limited to the substantia nigra and basal ganglia.

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 dont 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.

How Is A Diagnosis Made

How does Parkinsons disease affect the body?

Because other conditions and medications mimic the symptoms of PD, getting an accurate diagnosis from a physician is important. No single test can confirm a diagnosis of PD, because the symptoms vary from person to person. A thorough history and physical exam should be enough for a diagnosis to be made. Other conditions that have Parkinsons-like symptoms include Parkinsons plus, essential tremor, progressive supranuclear palsy, multi-system atrophy, dystonia, and normal pressure hydrocephalus.

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.

Is Parkinson’s Diagnosed In The Brain

Parkinson’s disease is one of the most challenging neurological disorders to diagnose and treat. If your doctor suspects you have Parkinson’s disease, you will usually be referred to a neurologist for further tests. These tests will involve certain movements and exercises to check your symptoms.

A neurologist will look for motor symptoms such as:

  • A tremor that occurs at rest
  • Slowed movement
  • Muscle stiffness

If you have two or more of these symptoms and your doctor has taken blood tests to rule out other causes, it’s likely you will be diagnosed with Parkinson’s disease. Your symptoms will be closely monitored to see any progression of Parkinson’s disease, which can take years.

Risks And Side Effects Of Deep Brain Stimulation

Like any surgery, deep brain stimulation can have side effects, and it carries potential risks. Its also important to consider the complications and side effects of medications you take since their dosages can often be reduced following surgery.

While DBS may cause side effects, it may also reduce side effects from medications.

What To Expect After Dbs

Surgery to implant the leads generally entails an overnight stay, while the IPG is usually implanted as same-day surgery. During recovery, your surgeon will talk to you about caring for your wounds, when you can shower, and any activity restrictions. Its usually recommended that any heavy lifting be avoided for a few weeks.

After another two to four weeks, youll return to have your device programmed. This process will continue for several weeks to ensure the stimulation settings are optimal to control your symptoms. During these visits, you will be shown how to turn the device on and off with the handheld device and check the battery level.

Once the programming has been completed, you will have regular follow-up visits to check and adjust the stimulation to maintain the most benefit for your symptoms.

Causes Of Parkinson’s Disease

Parkinson’s disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain.

Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinson’s disease.

Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.

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 .

What Are The Complications Of Parkinson Disease

Parkinson

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
  • Forgetfulness
  • 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.

Is There A Parkinson’s Disease Brain Scan

MRI brain scans and single photon emission computed tomography scans are often performed to rule out other causes of your symptoms, including strokes or a brain tumor. However, neither of these scans are diagnostic of Lewy bodies. There is no Parkinson’s disease brain scan, and no tests can conclusively show that you have Parkinson’s disease.

Cognitive Changes In Pd

Cognitive symptoms in Parkinsons disease are common, though not every person experiences them. In some people with PD, the cognitive changes are mild. In others, however, cognitive deficits may become more severe and impact daily functioning. Similar to slowness of movement , people with Parkinsons disease often report slower thinking and information processing . Attention and working memory, executive function, and visuospatial function are the most frequently affected cognitive domains in PD.

Cognitive deficits that are mild and do not impair ones ability to carry out activities of daily living have been termed mild cognitive impairment. Studies estimate that mild cognitive impairment occurs in about 20-50% of patients with PD. We now recognize that mild cognitive changes may be present at the time of Parkinsons disease diagnosis or even early in the course of PD. They may or may not be noticeable to the person. They may or may not affect work or activities, depending on the demands of specific tasks and work situations.

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

How Are These Mental Health Problems Treated

Parkinson’s Disease: How is the brain affected?

Your doctor will first want to check if your hallucinations, delusions, or paranoia are caused by other medical conditions. They’ll check for imbalances in chemicals in your blood that help send nerve signals.

They may also check to see how well your kidney, liver, or lungs are working, as well as test for certain infections. All of these issues could cause mental health problems.

Other medications that you may be using, including over-the-counter drugs, could also play a role in your mental health. Tell your doctor about all the medicines you take, including herbs and supplements.

Often the medications used to treat Parkinson’s disease can cause mental health problems. Your doctor may suggest you switch to a different drug or change your dose. If changing your Parkinson’s medication causes your Parkinson’s symptoms to get worse, your doctor may recommend you stick with it but take antipsychotic drugs at the same time.

There’s a chance that an antipsychotic medicine you take is making your Parkinson’s worse. If that happens, you have alternatives. The medication pimavanserin was approved by the FDA to specifically treat psychosis that goes along with Parkinson’s disease. Other drugs, such as olanzapine , quetiapine , and clozapine can control hallucinations at low doses without making your Parkinson’s symptoms worse.

If you feel depressed or notice any mental health problems, talk to your doctor right away. There’s likely a remedy that will make you feel better.

How Does Parkinsons Affect The Mind

As aforementioned, Parkinsons can heavily impact the physical well-being of an individual that is experiencing serious complications and symptoms of the disease. However, just as an individual starts to feel the physical impacts on their body, their mental state and well-being may start to feel compromised as well. If an individual that has been faithfully running 5 miles a day starts to lose balance due to complications of Parkinsons Disease, he or she will likely start to feel depressed, anxious and sad over their inability to carry out their daily tasks.

As a seniors Parkinsons Disease starts to worsen over time, family members may start to see a shift in their overall mood and mental state. Not only can Parkinsons literally take an individuals ability to think clearly, but he or she may start to feel things that they had never felt before such as depression or anxiety. This can be one of many mental complications from this debilitation disease. Parkinsons can cause an individual to feel unmotivated to carry out everyday tasks or to put effort into improving their quality of life, as they may feel their life is declining anyways. It is important to recognize the signs of depression and mental health issues in seniors and know when it is time to step in and help them. Mental and emotional issues may start to heavily impact people with Parkinsons, as it may take away their drive and willingness to work towards a healthier and happier lifestyle.

General Anesthesia And Parkinsons Disease

C.-W. CHEN, K.-B. CHEN, Y.-C. KUO

Session Time: 1:45pm-3:15pm

Location: Exhibit Hall C

Objective: Postoperative cognitive dysfunction is common among the elderly. These changes may even be so severe that some elderly people actually become demented after undergoing an operation. There was minimal evidence to support continued postoperative cognitive decline beyond 5 years or more. The aim of this study is to explore whether general anesthesia impact the incidence of Parkinsons disease in nationwide population.

Background: Parkinsons disease is one of the important diseases among older population and leads to disability. The exact mechanism of PD is variant. Whether general anesthesia is a potential risk factor for the development of PD is controversial. Therefore, this study aimed to evaluate the association between previous exposure to different types of GA and the incidence of PD.

Methods: Using claims data of 1,000,000 insured residents covered in the national health insurance, we enrolled 4,931 newly diagnosed dementia cases with age more than 50 years-old in 2005-2009. The control group of 19,720 individuals without PD was matched for age, gender, and index date. GA were categorized as three subtypes, including endotracheal tube intubation general anesthesia , intravenous injection general anesthesia or intramuscular injection general anesthesia , and heavy sedation. Multivariate logistic regression model was used for analyses.
