How Parkinson’s Disease Affects the Body — The Doctors

Parkinson disease can be hard to diagnose. No single test can identify it. Parkinson can be easily mistaken for another health condition. A healthcare provider will usually take a medical history, including a family history to find out if anyone else in your family has Parkinsons disease. He or she will also do a neurological exam. Sometimes, an MRI or CT scan, or some other imaging scan of the brain can identify other problems or rule out other diseases.

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.

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.

What Exactly Are Lewy Bodies

Lewy bodies are “clumps” of protein that accumulate in the outer layers of the brain, also known as the cortex. In addition to Parkinson’s, they are also a feature of dementia. Although we don’t know precisely what part Lewy bodies play in Parkinson’s disease or dementia, we do know that they are not the sole cause of Parkinson’s disease and its various symptoms. Some studies indicate that dopamine cells die before they even reach this part of the brain, but this is unconfirmed.

Despite the enigma of the Parkinson’s brain, many scientists have identified Lewy bodies as a potential target for new treatments. These treatments for Parkinson’s disease could be available in a matter of years, not decades.

How Does Parkinsons Affect The Body

Back Conditions

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 Are The Symptoms

Symptoms of PD vary from person to person, as does the rate of progression. A person who has Parkinson’s may experience some of these more common “hallmark” symptoms:

  • Bradykinesia – slowness of movement, impaired dexterity, decreased blinking, drooling, expressionless face.
  • Tremor at rest – involuntary shaking that decreases with purposeful movement. Typically starts on one side of the body, usually the hand.
  • Rigidity – stiffness caused by involuntary increase in muscle tone.
  • Postural instability – sense of imbalance. Patients often compensate by lowering their center of gravity, which results in a stooped posture.

Other symptoms that may or may not occur:

Freezing or being stuck in place Shuffling gait or dragging of one foot Stooped posture Cognitive impairment

Medications For People With Parkinsons Disease

Symptoms of Parkinsons disease result from the progressive degeneration of nerve cells in the brain and other organs such as the gut, which produce a neurotransmitter called dopamine. This causes a deficiency in the availability of dopamine, which is necessary for smooth and controlled movements. Medication therapy focuses on maximising the availability of dopamine in the brain. Medication regimes are individually tailored to your specific need. Parkinsons medications fit into one of the following broad categories:

  • levodopa dopamine replacement therapy
  • dopamine agonists mimic the action of dopamine
  • COMT inhibitors used along with levodopa. This medication blocks an enzyme known as COMT to prevent levodopa breaking down in the intestine, allowing more of it to reach the brain
  • anticholinergics block the effect of another brain chemical to rebalance its levels with dopamine
  • amantadine has anticholinergic properties and improves dopamine transmission
  • MAO type B inhibitors prevent the metabolism of dopamine within the brain.

Surgery For People With Parkinsons Disease

Deep brain stimulation surgery is an option to treat Parkinsons disease symptoms, but it is not suitable for everyone. There are strict criteria and guidelines on who can be a candidate for surgery, and this is something that only your doctor and you can decide. Surgery may be considered early or late in the progression of Parkinsons. When performing deep-brain stimulation surgery, the surgeon places an electrode in the part of the brain most effected by Parkinsons disease. Electrical impulses are introduced to the brain, which has the effect of normalising the brains electrical activity reducing the symptoms of Parkinsons disease. The electrical impulse is introduced using a pacemaker-like device called a stimulator. Thalamotomy and pallidotomy are operations where the surgeon makes an incision on part of the brain. These surgeries aim to alleviate some forms of tremor or unusual movement, but they are rarely performed now.

What is Parkinson’s Disease?

Parkinson ‘s disorder and its connection to the anatomy of the human body. Parkinson ‘s is a progressive disorder of the nervous system that affects movement due to the loss of Dopamine. Dopamine which is a neurotransmitter located in the brain allows signals to be transported from one nerve cell to another. Its purpose is to regulate both movement and cognition. The loss of these chemical messengers can cause both stiffness of the body and tremors, which are two common effects of Parkinson ‘s. Throughout

Beyond The Substantia Nigra

In Parkinsons, other areas of the brain beyond the substantia nigra are involved as the condition progresses. Changes in higher brain areas are linked to non-motor symptoms that can affect people with Parkinsons later on in the condition, and often have a significant impact on quality of life.

For instance, symptoms that affect memory and thinking can be linked to the presence of Lewy bodies in the largest area of the brain the cerebral cortex as well as the limbic system. The limbic system is also believed to be involved in symptoms involving mood and pain, and similar changes in the inferior temporal gyrus, an area of the brain involved in processing what we see, are thought to be the reason for hallucinations.

But research into the spread of Parkinsons through these areas, and how we can stop it , is just one side of the story. There is also ongoing research into where Parkinsons starts, and the effects it is having before it reaches these areas.

The presence of non-motor symptoms many months and maybe even years before the physical symptoms, such as tremor and slowness of movement, points towards the presence of other changes in the body long before the loss of dopamine-producing cells in the substantia nigra. These early symptoms could even help researchers predict those who will go on to be diagnosed with Parkinsons, which would help in the development of new and better treatments.

What Is Parkinson’s Disease

Parkinsons disease is a degenerative, progressive disorder that affects nerve cells in deep parts of the brain called the basal ganglia and the substantia nigra. Nerve cells in the substantia nigra produce the neurotransmitter dopamine and are responsible for relaying messages that plan and control body movement. For reasons not yet understood, the dopamine-producing nerve cells of the substantia nigra begin to die off in some individuals. When 80 percent of dopamine is lost, PD symptoms such as tremor, slowness of movement, stiffness, and balance problems occur.

Body movement is controlled by a complex chain of decisions involving inter-connected groups of nerve cells called ganglia. Information comes to a central area of the brain called the striatum, which works with the substantia nigra to send impulses back and forth from the spinal cord to the brain. The basal ganglia and cerebellum are responsible for ensuring that movement is carried out in a smooth, fluid manner .

The action of dopamine is opposed by another neurotransmitter called acetylcholine. In PD the nerve cells that produce dopamine are dying. The PD symptoms of tremor and stiffness occur when the nerve cells fire and there isn’t enough dopamine to transmit messages. High levels of glutamate, another neurotransmitter, also appear in PD as the body tries to compensate for the lack of dopamine.

Early Signs Of Parkinsons

Most people who are diagnosed with Parkinsons are 60 years of age or older, but early onset Parkinsons is possible, too.

In the first and second stages, the signs of Parkinsons are usually mild. Although 60-80% of the dopamine-producing cells in your brain are gone, you will still be able to go about your usual day-to-day activities.

Some of the most common symptoms during these stages include:

  • tremors in the hands, arms, feet, or other body parts when resting
  • stiffness and rigidity in muscles
  • Bradykinesia , which can also cause a mask-like appearance of the face due to a lack of facial expressions.

* Memories: Brain stores short-term memories of the experience in a part of the brain called the hippocampus, then those memories are later consolidated and transferred to another part of the brain, more precisely in neocortex, for a long-term storage Memory cells are placed in three parts of the brain, the hippocampus, the prefrontal cortex, and also the basolateral amygdala, which is responsible of emotional associations. In fact these cells are necessary to evoke the emotions linked with

Medicines For Parkinsons Disease

Medicines prescribed for Parkinsons include:

  • Drugs that increase the level of dopamine in the brain
  • Drugs that affect other brain chemicals in the body
  • Drugs that help control nonmotor symptoms

The main therapy for Parkinsons is levodopa, also called L-dopa. Nerve cells use levodopa to make dopamine to replenish the brains dwindling supply. Usually, people take levodopa along with another medication called carbidopa. Carbidopa prevents or reduces some of the side effects of levodopa therapysuch as nausea, vomiting, low blood pressure, and restlessnessand reduces the amount of levodopa needed to improve symptoms.

People with Parkinsons should never stop taking levodopa without telling their doctor. Suddenly stopping the drug may have serious side effects, such as being unable to move or having difficulty breathing.

Other medicines used to treat Parkinsons symptoms include:

  • Dopamine agonists to mimic the role of dopamine in the brain
  • MAO-B inhibitors to slow down an enzyme that breaks down dopamine in the brain
  • COMT inhibitors to help break down dopamine
  • Amantadine, an old antiviral drug, to reduce involuntary movements
  • Anticholinergic drugs to reduce tremors and muscle rigidity

Does Parkinsons Affect Voice

The voice is affected too, because the voice box is ultimately controlled by the basal ganglia as well. Thus the voice becomes soft, slurred and hushed. Others may comment that the patient is mumbling. The mumbling goes away temporarily once the patient becomes aware of it but soon returns to the soft, slurred state.

This temporary improvement when attention is paid is true of many of the motor symptoms of PD because the condition primarily affects subconscious movements, and does not directly affect nerve or muscle control at the most basic level. Thus, conscious awareness can override the slowness to a certain extent. This fact is one reason why physical therapy and physical activity are so useful and necessary in treating PD.

  • Slowness of walking and other movements
  • Trouble with dexterity

Imbalance, loss of balance reflexes

  • May fall backwards

Drugs To Treat Parkinsons Disease

Study conducted by medical researchers have compared two drugs named Levodopa and Pramipexole, which is employed generally as the first treatment line associated with the parkinsons disease problem. These drugs use various mechanisms to counteract with declining in the dopamine production in human brain, which is a result of progressive cell loss to secrete neuro chemicals in human brain. Levodopa is a type of amino acid, which human body metabolizes to form dopamine. On the other side, Pramipexole is a type of dopamine agonist, which binds with dopamine receptors present on cells in human brain and mimics the molecular function associated with the chemical.

Diagnosis Of Parkinsons Disease

How PARKINSON’S Disease Affects the Body

A number of disorders can cause symptoms similar to those of Parkinson’s disease. People with Parkinson’s-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson’s, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson’s. Since many other diseases have similar features but require different treatments, it is important to make an exact diagnosis as soon as possible.

There are currently no blood or laboratory tests to diagnose nongenetic cases of Parkinson’s disease. Diagnosis is based on a person’s medical history and a neurological examination. Improvement after initiating medication is another important hallmark of Parkinson’s disease.

Advancement In Parkinsons Disease

With the progress of Parkinsons disease with time, symptoms associated with the problem become worse typically and many new problems emerge. Despite patients receive benefits with the intake of anti-Parkinson medication the benefit fails to last for a long time even when they intake it frequently.

Most of the patients usually experience involuntary movements to make them, as looking fidgety when they intake the medicine and otherwise works the best. Hence, it is very much essential to emphasize such movements typically and do not bother about the condition of patients too much.

Other problems, which may take place with the progress of Parkinsons disease, are-

  • Problems associated with balance and gait, along with falls
  • Difficulty in communication or impairment of speech
  • Difficulty in swallowing
  • Cognitive impairment, such as memory and thinking
  • Behavioral problems
  • Light-headedness.

Some of the problems are of very much difficult to treat with medicines. However, any experienced doctor or a neurologist specializes in movement disorder will still may provide the necessary support and guidance for patients even during the advanced phases of the Parkinsons disease.

How Parkinsons Disease Affects The Human Body

More than one million people live with Parkinsons disease in the U.S., but no two experiences are the same. Parkinsons affects individuals in vastly different ways: for some, Parkinsons may first show up as slight hand tremors, and in others, it might appear as an unusual level of stiffness. For one person it may progress slowly, and in someone else, it may spread frighteningly fast.

There are some consistencies in how the disease works, however, and understanding these similarities can help prepare for what to expect if you or a loved one is diagnosed with Parkinsons disease. From how it starts to how it progresses through its five stages, here are some of the ways Parkinsons affects the human body.

Parkinsons And Urinary Problems

Just as your digestive tract may become weaker, so can the muscles of your urinary tract system.

Parkinsons disease and medications prescribed for treatment can cause your autonomic nervous system to stop functioning properly. When that happens, you may begin experiencing urinary incontinence or difficulty urinating.

Parkinsons Doesnt Always Cause Dementia

How To Cure and What To Avoid in Parkinsons Disease ...

While cognitive decline is common in both Alzheimers and Parkinsons, it is less likely to occur in Parkinsons patients. According to studies, only half of those with Parkinsons develop cognitive difficulties. This can range from mild forgetfulness to full-blown dementia.

When dementia does manifest itself with Parkinson, it occurs in the subcortical area of the brain. Alzheimers dementia occurs in the cortical area of the brain. As a result of this, the clinical symptoms of these two dementias can be somewhat different.
