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.

Gait & Balance Abnormalities
Parkinsons Disease Exam
Patients with Parkinsons disease can develop an alteration of the postural reflexes that causes instability in gait and balance control. Such alterations usually develop later in the course of the illness and are a major cause of disability, especially because of the high risk for falls that derives.
Using the exam to pick up postural instability is of the utmost importance for the management of patients with PD, since it will trigger either a medication adjustment or a physical therapy intervention both aimed at falls prevention.
We have three tests for this part of the PD exam:
1) Standing up from a chair
2) Free walking
3) Provoked pull test maneuver for balance
Referral To A Specialist
If your GP suspects Parkinson’s disease, you’ll be referred to a specialist.
This will usually be:
- a neurologist, a specialist in conditions affecting the brain and nervous system
- a geriatrician, a specialist in problems affecting elderly people
The specialist will most likely ask you to perform a number of physical exercises so they can assess whether you have any problems with movement.
A diagnosis of Parkinson’s disease is likely if you have at least 2 of the 3 following symptoms:
- shaking or tremor in a part of your body that usually only occurs at rest
- slowness of movement
- muscle stiffness
If your symptoms improve after taking a medication called levodopa, it’s more likely you have Parkinson’s disease.
Special brain scans, such as a single photon emission computed tomography scan, may also be carried out in some cases to try to rule out other causes of your symptoms.

What Is Essential Tremor And How Is It Different To A Parkinsons Tremor
A tremor is a rhythmical, involuntary movement that affects a part of the body, such as the hand.
Essential tremor is the most common type of tremor. Its most noticeable when your hands are doing something and it usually affects both the right and left sides of the body equally. Essential tremors often lessen when your body is resting.
Unlike an essential tremor, a Parkinsons tremor is most obvious when the affected body part is resting and tends to be less noticeable with movement. It usually starts on one side of the body and may progress to the other side as Parkinsons develops.
The time it takes to get a diagnosis can vary from person to person. Some people may receive a diagnosis of Parkinsons quite quickly, but for others it may be a long process. This can be due to a number of things, including your medical history, your age and what symptoms you have.
Your specialist may wish to rule out other causes of your symptoms first and see how you respond to treatment. This may take some time, and, as already mentioned, there is currently no definitive test for Parkinsons.
How you respond to treatment may help your specialist make a diagnosis. Keeping a diary or record of your symptoms will give the specialist more information to guide their decision.
Because the symptoms of Parkinsons are sometimes similar to other forms of parkinsonism, people can sometimes be misdiagnosed.
Complementary And Alternative Therapies
Some people with Parkinson’s disease find complementary therapies help them feel better. Many complementary treatments and therapies claim to ease the symptoms of Parkinson’s disease.
However, there’s no clinical evidence they’re effective in controlling the symptoms of Parkinson’s disease.
Most people think complementary treatments have no harmful effects. However, some can be harmful and they shouldn’t be used instead of the medicines prescribed by your doctor.
Some types of herbal remedies, such as St John’s wort, can interact unpredictably if taken with some types of medication used to treat Parkinson’s disease.
If you’re considering using an alternative treatment along with your prescribed medicines, check with your care team first.

What Are The Treatments
Currently there is no cure for Parkinsons disease.
Symptoms can be mild in the early stages of the condition and people might not need immediate treatment. Your doctor and specialist will monitor your situation.
There are several different types of drugs used to treat Parkinsons disease. Drug treatments are tailored to each individuals needs and are likely to involve a combination of different drugs. Your medication should be reviewed regularly. It is likely that, over time, changes will be made to the types of drugs you take and the doses you take each day.
The main types of drug treatment for Parkinsons disease are:
- drugs which replace dopamine
- drugs which mimic the role of dopamine
- drugs which inhibit the activity of acetylcholine
- drugs which prevent the body breaking down dopamine
- other drugs such as anti-sickness medication
Everybody is affected differently by medication. The possible side effects of Parkinsons disease drugs include nausea , vomiting , tiredness and dizziness. Some people might experience confusion, nightmares and hallucinations. For some people, dopamine agonists have been linked to compulsive behaviour such as addictive gambling or hypersexuality .
The effectiveness of the main drug treatment levodopa can wear off over time and its long-term use can cause some people to develop involuntary twisting or writhing movements of the arms, legs or face . To reduce the risk, doctors might delay the use of levodopa for younger people.
Learn Everything You Can About The Disease
Parkinsons disease is a movement disorder. If youre a caregiver for someone living with Parkinsons, youre likely familiar with some of the symptoms of the disease. But do you know what causes its symptoms, how the condition progresses, or what treatments can help manage it? Also, Parkinsons doesnt manifest the same way in everyone.
To be the best ally for your loved one, learn as much as you can about Parkinsons disease. Do research on reputable websites like the Parkinsons Foundation, or read books about the condition. Tag along for medical appointments and ask the doctor questions. If youre well informed, youll have a better idea of what to expect and how to be the most help.

Living With Parkinson’s Disease
Coming to terms with a diagnosis of Parkinson’s and living with the disease is challenging and will take a lot of adjustment. There are still things you can do that can help you to feel more in control of your situation and to stay positive. Some things that might help could include:
- choosing to lead a healthy lifestyle
- making informed decisions related to your treatment
- keeping a diary of your symptoms in preparation for meetings with health and social care professionals
- attending a self-management course
Anesthetic Management For Steriotactic Pallidotomy/thalamotomy
Classically local anesthesia with minimal or no sedation has been used for patients undergoing stereotactic procedures. This allows for patient participation in target localization and immediate observation of effects of test and lesion. Antiparkinsonian mediations are withheld for 1224 h prior to surgery. Therapy for concurrent diseases must be continued till the day of surgery.
Under LA, in magnetic resonance imaging suite stereotactic frame applied. Extra padding and rolls can make the patient more comfortable. Also these patients are very motivated to co-operate, unless there is dementia present. LA again is used to do burr hole and if the patient becomes agitated, midazolam can be titrated to desired effect. It is important that level of sedation does not impair co-operation or interfere with communication between surgeon and patient. Age, varying levels of dementia, fatigue, and cumulative effects of medication make it necessary to titrate the drugs slowly. Since propofol may elicit abnormal movements and may at times improve parkinsonian tremor, it might not be ideally suited for patients with movement disorders undergoing functional stereotactic neurosurgery.

What Tests Diagnose Parkinson’s Disease
There currently are no tests that can definitively diagnose Parkinsons Disease. A diagnosis is based on the clinical findings of your physician in combination with your report on the symptoms you are experiencing.
In situations where an older person presents with the typical features of Parkinsons and they are responsive to dopamine replacement therapy, there is unlikely to be any benefit to further investigation or imaging.

Depression May Be An Early Symptom Of Parkinsons
Depression is one of the most common, and most disabling, non-motor symptoms of Parkinsons disease. As many as 50 per cent of people with Parkinsons experience the symptoms of clinical depression at some stage of the disease. Some people experience depression up to a decade or more before experiencing any motor symptoms of Parkinsons.
Clinical depression and anxiety are underdiagnosed symptoms of Parkinsons. Researchers believe that depression and anxiety in Parkinsons disease may be due to chemical and physical changes in the area of the brain that affect mood as well as movement. These changes are caused by the disease itself.
Here are some suggestions to help identify depression in Parkinsons:
- Mention changes in mood to your physician if they do not ask you about these conditions.
- Complete our Geriatric Depression Scale-15 to record your feelings so you can discuss symptoms with your doctor. Download the answer key and compare your responses.
- delusions and impulse control disorders
How Is Parkinson’s Diagnosed
Current evidence suggests that Parkinsons tends to develop gradually. It may be many months, even years, before the symptoms become obvious enough for someone to go to the doctor.
This information looks at what parkinsonism is, how Parkinsons and other similar conditions may be diagnosed, and explains some of the tests that may be involved in the process.
Parkinsonism is a term used to describe symptoms or signs that are found in Parkinsons, but which can also be found in other conditions that cause slowness of movement, stiffness and tremor.
Most people with a form of parkinsonism have idiopathic Parkinsons disease, also known as Parkinsons. Idiopathic means the cause is unknown.
Other less common forms of parkinsonism include multiple system atrophy , progressive supranuclear palsy , drug-induced parkinsonism and vascular Parkinsons.
If youre concerned about symptoms youve been experiencing, you should visit your GP. If your GP suspects you have Parkinsons, clinical guidelines recommend they should refer you quickly to a specialist with experience in diagnosing the condition .
Its not always easy to diagnose the condition. So its important that you see a Parkinsons specialist to get an accurate diagnosis and to consider the best treatment options.
Diagnosing Parkinsons can take some time as there are other conditions, such as essential tremor , with similar symptoms. There is also currently no definitive test for diagnosing Parkinsons.

Drugs And Medication Used To Treat Parkinsons Disease
A number of different drugs can be used to treat Parkinsons.
Levodopa
Levodopa is the most common treatment for Parkinsons. It helps to replenish dopamine.
About 75 percent of cases respond to levodopa, but not all symptoms are improved. Levodopa is generally given with carbidopa.
Carbidopa delays the breakdown of levodopa which in turn increases the availability of levodopa at the blood-brain barrier.
Dopamine agonists
Dopamine agonists can imitate the action of dopamine in the brain. Theyre less effective than levodopa, but they can be useful as bridge medications when levodopa is less effective.
Drugs in this class include bromocriptine, pramipexole, and ropinirole.
Anticholinergics
Anticholinergics are used to block the parasympathetic nervous system. They can help with rigidity.
Benztropine and trihexyphenidyl are anticholinergics used to treat Parkinsons.
Amantadine
Amantadine can be used along with carbidopa-levodopa. Its a glutamate-blocking drug . It offers short-term relief for the involuntary movements that can be a side effect of levodopa.
COMT inhibitors
Catechol O-methyltransferase inhibitors prolong the effect of levodopa. Entacapone and tolcapone are examples of COMT inhibitors.
Tolcapone can cause liver damage. Its usually saved for people who do not respond to other therapies.
Ectacapone does not cause liver damage.
Stalevo is a drug that combines ectacapone and carbidopa-levodopa in one pill.
MAO-B inhibitors
Is Early Diagnosis Possible
Experts are becoming more aware of symptoms of Parkinsons that precede physical manifestations. Clues to the disease that sometimes show up before motor symptoms and before a formal diagnosis are called prodromal symptoms. These include the loss of sense of smell, a sleep disturbance called REM behavior disorder, ongoing constipation thats not otherwise explained and mood disorders, such as anxiety and depression.
Research into these and other early symptoms holds promise for even more sensitive testing and diagnosis.
For example, biomarker research is trying to answer the question of who gets Parkinsons disease. Researchers hope that once doctors can predict that a person with very early symptoms will eventually get Parkinsons disease, those patients can be appropriately treated. At the very least, these advances could greatly delay progression.
Parkinson’s Disease and Movement Disorders Center
Our center provides compassionate and timely treatment to patients with movement disorders, such as dystonia, ataxia, essential tremor and similar conditions.

Diagnosis And Management Of Parkinsons Disease
There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.
No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.
People can manage their Parkinsons disease symptoms through:
- seeing a Doctor who specialises in Parkinsons
- medication
- multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
- deep brain stimulation surgery .
Is There A Cure For Parkinsons
Theres currently no cure for Parkinsons, a disease that is chronic and worsens over time. More than 50,000 new cases are reported in the United States each year. But there may be even more, since Parkinsons is often misdiagnosed.
Its reported that Parkinsons complications was the
Complications from Parkinsons can greatly reduce quality of life and prognosis. For example, individuals with Parkinsons can experience dangerous falls, as well as blood clots in the lungs and legs. These complications can be fatal.
Proper treatment improves your prognosis, and it increases life expectancy.
It may not be possible to slow the progression of Parkinsons, but you can work to overcome the obstacles and complications to have a better quality of life for as long as possible.
Parkinsons disease is not fatal. However, Parkinsons-related complications can shorten the lifespan of people diagnosed with the disease.
Having Parkinsons increases a persons risk for potentially life threatening complications, like experiencing:
- falls
Parkinsons often causes problems with daily activities. But very simple exercises and stretches may help you move around and walk more safely.

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 .
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
