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:
Parkinsons often causes problems with daily activities. But very simple exercises and stretches may help you move around and walk more safely.
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:
- 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.

Parkinsons Disease: The Essentials
If youre new to Parkinsons disease and would like a good overview to help you better understand the disease, please view our Parkinsons Disease: The Essentials presentation. Its a great place to get started with reliable and concise information.
The exact cause of Parkinsons is still unknown, but there is an enormous amount of research being done to learn more. This research has led scientists to formulate a number of theories on the cause of this disease.
While there is no definitive test that can be taken to determine whether a person has Parkinsons disease, movement disorder specialists look for symptoms and use brain imaging technology to accurately diagnose Parkinsons.
Even though Parkinsons is classified as a movement disorderand its motor symptoms are the most discussed and well-knownthere are many non-motor symptoms that display in people with Parkinsons as well.
As of today, there is no cure for Parkinsons disease. But there are many ways in which the disease can be treated to make symptoms more manageable.

What Treatments Are Available
Many Parkinson’s 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. Parkinson’s 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 Parkinson’s. 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.
Pathophysiology Of Parkinsons Disease
Although we are learning more each day about the pathophysiology of Parkinsons disease, it is still considered largely idiopathic . It likely involves the interaction of host susceptibility and environmental factors. A small percentage of cases are genetically linked and genetic factors are being intensely studied.
Physiologically, the symptoms associated with Parkinsons disease are the result of the loss of a number of neurotransmitters, most notably dopamine. Symptoms worsen over time as more and more of the cells affected by the disease are lost. The course of the disease is highly variable, with some patients exhibiting very few symptoms as they age and others whose symptoms progress rapidly.
Parkinsons is increasingly seen as a complex neurodegenerative disease with a sequence of progression. There is strong evidence that it first affects the dorsal motor nucleus of the vagus nerve and the olfactory bulbs and nucleus, then the locus coeruleus, and eventually the substantia nigra. Cortical areas of the brain are affected at a later stage. Damage to these various neuronal systems account for the multi-faceted pathophysiologic changes that cause impairments not just to the motor system but also to the cognitive and neuropsychological systems .

What Are The Causes
The cause of Parkinson’s is largely unknown. Scientists are currently investigating the role that genetics, environmental factors, and the natural process of aging have on cell death and PD.
There are also secondary forms of PD that are caused by medications such as haloperidol , reserpine , and metoclopramide .
Diagnosis Of Parkinsons Disease
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.

The Evolution Of Treatments
The history of Parkinson’s disease is tightly linked to therapeutic interventions, ranging from serendipitous observations to controlled clinical trials of specifically designed agents.
Parkinson devoted a chapter of his monograph to considerations respecting the means of cure . In humility and perhaps with a vision toward current concepts of neuroprotection, he hoped for the identification of a treatment by which the progress of the disease may be stopped . To this end, he advocated very early therapeutic intervention when signs were largely confined to the arms without balance and gait impairments. Reflecting therapeutic approaches of the early nineteenth century, Parkinson recommended venesection, specifically advocating bloodletting from the neck, followed by vesicatories to induce blistering and inflammation of the skin. Small pieces of cork were purposefully inserted into the blisters to cause a sufficient quantity of purulent discharge . All these efforts were designed to divert blood and inflammatory pressure away from the brain and spinal cord, and in this way, decompress the medulla that Parkinson considered the seat of neurological dysfunction.
Who Does The Disease Affect
There are an estimated 1 million people in the U.S. living with Parkinsons disease and more than 10 million people worldwide. Most people who develop the symptoms of Parkinsons disease do so sometime after the age of 50, but Parkinsons disease can affect younger persons as well. Approximately 10% of Parkinsons diagnoses occur before age 50these diagnoses are called Early Onset Parkinsons disease.

Clinical History And Testing
Diagnostic tests can be used to establish some features of the condition and distinguish them from symptoms of other conditions. Diagnosis may include taking the person’s , a physical exam, assessment of neurological function, testing to rule out conditions that may cause similar symptoms, brain imaging, to assess cognitive function,, or myocardial scintigraphy. Laboratory testing can rule out other conditions that can cause similar symptoms, such as abnormal , , , or vitamin deficiencies that may cause symptoms similar to dementia.
Typical dementia screening tests used are the and the . The pattern of cognitive impairment in DLB is distinct from other dementias, such as AD the MMSE mainly tests for the memory and language impairments more commonly seen in those other dementias and may be less suited for assessing cognition in the Lewy body dementias, where testing of visuospatial and executive function is indicated. The MoCA may be better suited to assessing cognitive function in DLB, and the scale and the may help understand cognitive decline relative to fluctuations in DLB. For tests of attention, , , and can be used for simple screening, and the Revised Digit Symbol Subtest of the may show defects in attention that are characteristic of DLB. The , and are used for evaluation of executive function, and there are many other screening instruments available.
How Will The Disease Affect My Life
Most people who have Parkinsonâs live a normal to a nearly normal lifespan, but the disease can be life changing.
For some people, treatment keeps the symptoms at bay, and they’re mostly mild. For others, the disease is much more serious and really limits what you’re able to do.
As it gets worse, it makes it harder and harder to do daily activities like getting out of bed, driving, or going to work. Even writing can seem like a tough task. And in later stages, it can cause dementia.
Even though Parkinson’s can have a big impact on your life, with the right treatment and help from your health care team, you can still enjoy the things you love. It’s important to reach out to family and friends for support. Learning to live with Parkinson’s means making sure you get the backing you need.

Rest And Action Tremor
We noted above that action tremor can contribute to weakness in Parkinson’s disease. In addition, rest and action tremor can also be a factor in prolonging reaction times. Hallett and colleagues and Wierzbicka and colleagues showed that patients with Parkinson’s disease tend to time the onset of agonist muscle activity at the elbow or wrist with the time of activation of the same muscle in any ongoing tremor . This could, on average, slow the initiation of any movement.
Action tremor can also be a factor in pacing the speed of voluntary alternating movements. Logigian and colleagues showed that voluntary movements are entrained by action tremor if patients attempt to move at frequencies close to that of their natural action tremor . The extent of the entrainment depends on the amplitude of the patients’ ongoing tremor.
How Will My Doctor Test For It
There’s no one test for Parkinson’s. A lot of it’s based on your symptoms and health history, but it could take some time to figure it out. Part of the process is ruling out other conditions that look like Parkinson’s. The docotor may do a DaT scan, which looks for dopamine in the brain. This can aid in a diagnosis.
Because there is no single test, it’s very important to go to a doctor who knows a lot about it, early on. It’s easy to miss.
If you do have it, your doctor might use what’s called the Hoehn and Yahr scale to tell you what stage of the disease you’re in. It ranks how severe your symptoms are from 1 to 5, where 5 is the most serious.
The stage can help you get a better feel for where your symptoms fall and what to expect as the disease gets worse. But keep in mind, some people could take up to 20 years to move from mild to more serious symptoms. For others, the change is much faster.

Dementia With Lewy Bodies
- Dementia with Lewy bodies is a progressive, neurodegenerative disorder in which abnormal deposits of a protein called alpha-synuclein build up in multiple areas of the brain.
- Dementia with Lewy bodies is second to Alzheimers as the most common cause of degenerative dementia that first causes progressive problems with memory and fluctuations in thinking, as well as hallucinations. These symptoms are joined later in the course of the disease by parkinsonism with slowness, stiffness and other symptoms similar to PD.
- While the same abnormal protein is found in the brains of those with PD, when individuals with PD develop memory and thinking problems it tends to occur later in the course of the disease.
- There are no specific treatments for DLB. Treatment focuses on symptoms.
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.

The Nervous System & Dopamine
To understand Parkinson’s, it is helpful to understand how neurons work and how PD affects the brain .
Nerve cells, or neurons, are responsible for sending and receiving nerve impulses or messages between the body and the brain. Try to picture electrical wiring in your home. An electrical circuit is made up of numerous wires connected in such a way that when a light switch is turned on, a light bulb will beam. Similarly, a neuron that is excited will transmit its energy to neurons that are next to it.
Neurons have a cell body with branching arms, called dendrites, which act like antennae and pick up messages. Axons carry messages away from the cell body. Impulses travel from neuron to neuron, from the axon of one cell to the dendrites of another, by crossing over a tiny gap between the two nerve cells called a synapse. Chemical messengers called neurotransmitters allow the electrical impulse to cross the gap.
Neurons talk to each other in the following manner :
How Is Parkinson’s Disease Treated
If a doctor thinks a person has Parkinson’s disease, there’s reason for hope. Medicine can be used to eliminate or improve the symptoms, like the body tremors. And some experts think that a cure may be found soon.
For now, a medicine called levodopa is often given to people who have Parkinson’s disease. Called “L-dopa,” this medicine increases the amount of dopamine in the body and has been shown to improve a person’s ability to walk and move around. Other drugs also help decrease and manage the symptoms by affecting dopamine levels. In some cases, surgery may be needed to treat it. The person would get anesthesia, a special kind of medicine to prevent pain during the operation.

Medicines For Parkinson’s Disease
Medicines prescribed for Parkinson’s 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 Parkinson’s is levodopa, also called L-dopa. Nerve cells use levodopa to make dopamine to replenish the brain’s 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 Parkinson’s 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
What Are The Symptoms Of Parkinson’s Disease
The symptoms of Parkinson’s disease include tremors or trembling difficulty maintaining balance and coordination trouble standing or walking stiffness and general slowness.
Over time, a person with Parkinson’s may have trouble smiling, talking, or swallowing. Their faces may appear flat and without expression, but people with Parkinson’s continue to have feelings even though their faces don’t always show it. Sometimes people with the disease can have trouble with thinking and remembering too.
Because of problems with balance, some people with Parkinson’s fall down a lot, which can result in broken bones. Some people with Parkinson’s may also feel sad or depressed and lose interest in the things they used to do.
The symptoms of Parkinson’s disease appear gradually and get worse over time. But because Parkinson’s disease usually develops slowly, most people who have it can live a long and relatively healthy life.

Changes Inside The Brain
In Parkinson disease, nerve cells in part of the basal ganglia degenerate.
The basal ganglia are collections of nerve cells located deep within the brain. They help do the following:
Initiate and smooth out intended muscle movements
Suppress involuntary movements
Coordinate changes in posture
When the brain initiates an impulse to move a muscle , the impulse passes through the basal ganglia. Like all nerve cells, those in the basal ganglia release chemical messengers that trigger the next nerve cell in the pathway to send an impulse. A key neurotransmitter in the basal ganglia is dopamine. Its overall effect is to increase nerve impulses to muscles.
When nerve cells in the basal ganglia degenerate, they produce less dopamine, and the number of connections between nerve cells in the basal ganglia decreases. As a result, the basal ganglia cannot control muscle movement as they normally do, leading to tremor, slow movement , a tendency to move less , problems with posture and walking, and some loss of coordination.
