How Is Parkinson’s Disease Diagnosed
Someone with the symptoms of Parkinson’s disease may be sent to see a neurologist, a doctor who specializes in the brain, nerves, and muscles. The neurologist may do some tests, including a brain scan and blood tests. These tests will not make the diagnosis of Parkinson’s disease, but the doctor will want to make sure that there is no other problem causing the symptoms. To diagnose Parkinson’s disease, the doctor relies on a person’s medical history, symptoms, and a physical exam.
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 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 .
Stages Of Parkinsons Disease
Neurologists usually describe the progression of Parkinsons symptoms in stages, using the system known as the Hoehn and Yahr scale. These stages are:
- Stage I Symptoms are seen on one side of the body only.
- Stage II Symptoms are seen on both sides of the body. Theres no impairment of balance.
- Stage III Balance impairment has begun. In this mild- to moderate stage of the disease, the person is still physically independent.
- Stage IV This stage is marked by severe disability, but the person is still able to walk or stand unassisted.
- Stage V The person is wheelchair-bound or bedridden unless assisted.
Parkinson’s Disease Early Stages Detected With ‘simple’ Mri Up To 85% Accurate
Detecting a life-threatening disease could give researchers the power of earlier diagnosis, treatment approaches, and innovative therapies a power that could one day possibly lead to cure a disease like Parkinsons. Researchers from Oxford University published their findings in the journal of Neurology, which reveal a promising new diagnostic approach for the early stages of Parkinsons disease.
At the moment we have no way to predict who is at risk of Parkinson’s disease in the vast majority of cases, said Dr. Clare Mackay, the studys co-author and professor of the Department of Psychiatry at Oxford University. Oxford researchers are turning the tables on that bleak risk evaluation now that they have developed an expediently simple technique to diagnose early Parkinsons stages with a magnetic resonance imaging machine with 85 percent accuracy. A normal MRI scan cannot detect the early signs, which is why researchers used restating state functional MRI to look at how strong the brain connections were in the basal ganglia, where important dopamine nerves are located.
We think that our MRI test will be relevant for diagnosis of Parkinson’s, said Dr. Michele Hu, the studys co-author and professor of the Nuffield Department of Clinical Neurosciences at Oxford University and the Oxford University Hospitals NHS Trust.

A Bottle Neck To Neurological Health
I have noticed that a lot of people with Parkinsons Disease, and other neurological disorders too, such as Alzheimers, suffer with severe neck pain and/or stiff, rigid necks. In terms of neurological problems, our necks can be a pinch point – a constricted passageway or tunnel, through which all the superhighways between our brain and the rest of our nervous system and organs, and from there, out into the far reaches of our fingers and toes, must pass. All of our utilities, the two-way electrical wirings, the broadband and telegraph wires of the nervous system, the water and air supplies, the chemical pipelines providing nutrients and the sewer pipes taking away the excreta of the brain, must pass through this narrow gap. This is no ordinary tunnel: to keep these utility supplies open and running, it was designed to keep on moving itself and in truly extraordinary ways of flexible motions.
Even slight damage or stiffening up of the neck can cause constrictions or interruptions of these important electrical and chemical flows. For oxygen and nutrients that enter through the mouth or nose, it is double jeopardy, as they have to pass through the bottle-neck twice, down into the lungs or to the gut, and back up again to get the brain. The neck is therefore a primary attention site for progressive symptom reduction strategies. In this article, we look at aspects of the neck and consider what we can do to improve our lot.
What Are Lewy Bodies
The affected neurons of people with Parkinsons disease have been found to contain clumped proteins called Lewy bodies, but researchers arent yet sure why Lewy bodies form or what role they play in the disease.
Lewy bodies are clumps of a protein called alpha-synuclein . Neurons cant break down these protein clumps, which may lead to the death of these cells.
Some other theories about what causes the death of brain cells in people with Parkinsons disease include free radical damage, inflammation, or toxins.

Prevention Of Parkinsons Disease
Researchers dont know of any proven ways to prevent Parkinsons disease, but avoiding certain risk factors and adopting a healthy lifestyle may help reduce your risk.
Some studies have shown a diet high in antioxidants along with regular exercise may play a role in preventing Parkinsons. Other findings have suggested that compounds like caffeine, niacin, and nicotine may have a protective effect against Parkinsons disease.
How Can Hospice Help Your Loved One In The Final Stages Of Parkinsons Disease
Hospice care is an extra layer of support to help you care for your loved one with end-stage Parkinsons disease. It is a special kind of care that provides comfort, support, and dignity at the end of life.
The comprehensive program focuses on physical, emotional, and spiritual quality of life through the help of a team of experts. The team includes a board-certified physician, nurse, social worker, certified home health aide , spiritual support counselor, and volunteer.
The nurse will explain the prognosis and what to expect in the upcoming days or weeks. They will also monitor pain and other symptoms. The CHHA helps with personal care needs like bathing and changing bed linens. The social worker helps address social, emotional and practical challenges including complex and inter-related needs. The spiritual support counselor helps explore spiritual concerns.
Most importantly, the hospice team will be there for you during this difficult time, bringing you peace of mind. The team is on call 24 hours a day even at 2:00 am.
Hospice is about making your final months and weeks as good as possible. This means focusing on what really matters to you.
Stage One Of Parkinsons Disease
In stage one, the earliest stage, the symptoms of PD are mild and only seen on one side of the body , and there is usually minimal or no functional impairment.
The symptoms of PD at stage one may be so mild that the person doesnt seek medical attention or the physician is unable to make a diagnosis. Symptoms at stage one may include tremor, such as intermittent tremor of one hand, rigidity, or one hand or leg may feel more clumsy than another, or one side of the face may be affected, impacting the expression.
This stage is very difficult to diagnose and a physician may wait to see if the symptoms get worse over time before making a formal diagnosis.
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.

Treatment: Drugs That Make Dopamine
Parkinson’s affects nerve cells in your brain that make a chemical called dopamine. As a result, levels of the chemical fall. Doctors usually start treatment with levodopa . Your brain turns it into dopamine. But it can make you sick to your stomach, so youâll probably take it with another medicine called carbidopa to control these side effects. The combination drug is called carbidopa-levodopa .
What Are The Methods Of Coping With Parkinsons Disease
Affecting all spheres of life whether it is social or work-related, the nature of Parkinsons disease is progressive adversely. The gradual loss of independence may be difficult, but being well informed about the Parkinsons disease may reduce the anxiety to a large extent. There are various support groups that offer valuable information to patients with such disease and how to cope with the same. These groups provide emotional support and also advice the patients with regard to finding experienced doctors, therapists and other related information.

What Are The Primary Motor Symptoms Of Parkinsons Disease
There are four primary motor symptoms of Parkinsons disease: tremor, rigidity, bradykinesia and postural instability . Observing two or more of these symptoms is the main way that physicians diagnose Parkinsons.
It is important to know that not all of these symptoms must be present for a diagnosis of Parkinsons disease to be considered. In fact, younger people may only notice one or two of these motor symptoms, especially in the early stages of the disease. Not everyone with Parkinsons disease has a tremor, nor is a tremor proof of Parkinsons. If you suspect Parkinsons, see a neurologist or movement disorders specialist.
Walking or Gait Difficulties
Stage Four Of Parkinsons Disease
In stage four, PD has progressed to a severely disabling disease. Patients with stage four PD may be able to walk and stand unassisted, but they are noticeably incapacitated. Many use a walker to help them.
At this stage, the patient is unable to live an independent life and needs assistance with some activities of daily living. The necessity for help with daily living defines this stage. If the patient is still able to live alone, it is still defined as stage three.

What Is The Outlook For Persons With Parkinsons Disease
Although there is no cure or absolute evidence of ways to prevent Parkinsons disease, scientists are working hard to learn more about the disease and find innovative ways to better manage it, prevent it from progressing and ultimately curing it.
Currently, you and your healthcare teams efforts are focused on medical management of your symptoms along with general health and lifestyle improvement recommendations . By identifying individual symptoms and adjusting the course of action based on changes in symptoms, most people with Parkinsons disease can live fulfilling lives.
The future is hopeful. Some of the research underway includes:
- Using stem cells to produce new neurons, which would produce dopamine.
- Producing a dopamine-producing enzyme that is delivered to a gene in the brain that controls movement.
- Using a naturally occurring human protein glial cell-line derived neurotrophic factor, GDNF to protect dopamine-releasing nerve cells.
Many other investigations are underway too. Much has been learned, much progress has been made and additional discoveries are likely to come.
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.

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 :
Parkinsons Disease Symptoms Of Dementia
Up to one-third of people living with Parkinson’s disease experience dementia, according to the Parkinson’s Disease Foundation. Problems with dementia may include trouble with memory, attention span, and what is called executive function the process of making decisions, organizing, managing time, and setting priorities.

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
What Are The Risk Factors For Parkinsons Disease
Risk factors for Parkinsons disease include:
People with a first-degree relative with Parkinsons are at an increased risk for the disease possibly as much as 9 percent greater.
Fifteen to 25 percent of people with Parkinsons have a known relative with the disease, but a condition called familial Parkinsons, which has a known genetic link, is relatively rare.
The average age of onset is 60 years, and the incidence rises with advancing age. About 10 percent of people have early-onset or young-onset disease, which begins before age 50.
Parkinsons affects about 50 percent more men than women, for unknown reasons.
Exposure to some pesticides has been shown to raise the risk of developing Parkinsons.
Problematic chemicals include organochlorine pesticides like DDT, dieldrin, and chlordane. Rotenone and permethrin have also been implicated.
Fungicide and Herbicide Exposure
Exposure to the fungicide maneb or the herbicides 2,4-dichlorophenoxyacetic acid , paraquat, or Agent Orange may raise the risk of Parkinsons.
The U.S. Veterans Health Administration considers Parkinsons to be a possible service-related illness if the person was exposed to significant amounts of Agent Orange.
Head injuries may contribute to the development of Parkinsons in some people.
Coffee and Smoking
People who drink coffee or smoke tobacco have been found to have a lower risk of Parkinsons disease, for reasons that remain unclear.
