What Are The Stages Of Parkinsons
Doctors sometimes use five stages to describe the progress of Parkinsons disease. Each stage presents changing or new symptoms that a person is likely to encounter.
It is worth noting that not everyone will reach the advanced stages. For some people, the symptoms remain mild, and they can continue to live independently and be mobile.
Dividing the condition into stages helps doctors and caregivers understand and address some of the challenges a person is experiencing as it progresses.
Parkinsons Only Affects Movement
It is true that the medical community considers Parkinsons disease a motor disorder. However, people with the condition often also experience nonmotor symptoms, which can begin before the motor symptoms.
Nonmotor symptoms can include cognitive impairment or dementia, depression and anxiety, sleep dysfunction, pain, apathy, sexual dysfunction, and bowel incontinence.
People often overlook these symptoms, but they are important. As the authors of one paper on the topic explain:
onmotor symptoms dominate the clinical picture of advanced Parkinsons disease and contribute to severe disability, impaired quality of life, and shortened life expectancy.
effective drugs is levodopa, which the body converts into dopamine once it enters the brain.
There is a long standing myth that levodopa can only relieve symptoms for about 5 years before it stops working. This is a myth. Levodopa can be effective for decades. However, over time, its effectiveness might reduce.
Medical News Today spoke with James Beck, Senior Vice President and Chief Scientific Officer of the Parkinsons Foundation. He explained why levodopa becomes less potent:
One of the cruel ironies about Parkinsons disease is that the key enzyme that converts levodopa to dopamine is predominantly found in the dopamine neurons of the substantia nigra, which are lost during progression of the disease. So, the main way to make dopamine available to the Parkinsons brain declines as the disease advances.
Myth : Deep Brain Stimulation Is Experimental Therapy
Fact: Deep brain stimulation, or DBS, is a procedure in which doctors place electrodes in the brain at the point when medications are less effective in masking motor symptoms, such as tremor, stiffness and slowness of movement.
While it may sound frightening and futuristic, its been around and successfully used for decades. DBS works very similarly to a pacemaker, except the wire is in the brain, not in the heart. Its been a standard procedure for the past two decades.

Study Procedures And Assessments
Participants visit the study site three times for data collection: an initial baseline visit and two annual follow-up visits. Data collection during each visit takes a full day and can be spread out over a 1.5-day period if desired by the patient. Prior to each visit, study participants will be offered a complimentary hotel stay, thereby reducing the need for patients living far away from the study center to travel long distances in the early morning. Patients arrive at the study site in the morning in a practically defined OFF state, i.e., at least 12h after having taken their last dopaminergic PD medication.
Table 1 Overview of included study measures and scales in the Personalized Parkinson Project
After each visit participants complete a set of validated questionnaires at home, including questionnaires about medication use, quality of life, lifestyle, neuropsychological symptoms, autonomic symptoms, sleep, and vision, among others . These questionnaires are completed within 4weeks after each visit, via an online survey module.
Finally, a copy of the medical record of the participants primary care physician is requested. This provides a rich information source of known and unknown markers of disease progression.

Medication Not Working The Way It Used To
In the early stages, taking medicine works well to get rid of symptoms. But as Parkinsons progresses, your medication works for shorter periods of time, and symptoms return more easily. Your doctor will need to change your prescription.
Dr. Valerie Rundle-Gonzalez, a Texas-based neurologist, says to pay attention to how long your medicine takes to kick in and when it stops working. She says you should feel like symptoms significantly improve or are almost gone while on medication.

What Are The Complications Of Parkinson Disease
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.
Stage Three Of Parkinsons Disease
Stage three is considered mid-stage and is characterized by loss of balance and slowness of movement.
Balance is compromised by the inability to make the rapid, automatic and involuntary adjustments necessary to prevent falling, and falls are common at this stage. All other symptoms of PD are also present at this stage, and generally diagnosis is not in doubt at stage three.
Often a physician will diagnose impairments in reflexes at this stage by standing behind the patient and gently pulling the shoulders to determine if the patient has trouble maintaining balance and falls backward . An important clarifying factor of stage three is that the patient is still fully independent in their daily living activities, such as dressing, hygiene, and eating.

What Is Parkinsons Disease
Parkinsons disease is a progressive brain disorder that affects mobility and mental ability. If you or a loved one has been diagnosed with Parkinsons, you may be wondering about life expectancy.
According to some research, on average, people with Parkinsons can expect to live almost as long as those who dont have the condition.
What You Can Do
As of 2021, there is no definite cure for Parkinsons disease. There is also no definite known cause. Its likely due to a combination of an individuals susceptibility and environmental factors. Most cases of Parkinsons disease happen without a genetic link.
According to research published in 2012, only report having a family member with the disease. Many toxins are suspected and have been studied, but no single substance can be reliably linked to Parkinsons.
However, research is ongoing. Its estimated that

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.
What Is Parkinson Disease
Parkinson disease is a movement disorder. It can cause the muscles to tighten and become rigid This makes it hard to walk and do other daily activities. People with Parkinsons disease also have tremors and may develop cognitive problems, including memory loss and dementia.
Parkinson disease is most common in people who are older than 50. The average age at which it occurs is 60. But some younger people may also get Parkinson disease. When it affects someone younger than age 50, it’s called early-onset Parkinson disease. You may be more likely to get early-onset Parkinson disease if someone in your family has it. The older you are, the greater your risk of developing Parkinson disease. It’s also much more common in men than in women.
Parkinson disease is a chronic and progressive disease. It doesn’t go away and continues to get worse over time.

Increased Feelings Of Anxiety Or Depression
Anxiety and depression have been linked to Parkinsons. In addition to movement problems, the disease can also have an impact on your mental health. Its possible that changes in your emotional well-being can be a sign of changing physical health as well.
If you are more anxious than usual, have lost interest in things, or feel a sense of hopelessness, talk to your doctor.
Parkinsons Disease Is A Progressive Disorder
Parkinsons Disease is a slowly progressive neurodegenerative disorder that primarily affects movement and, in some cases, cognition. Individuals with PD may have a slightly shorter life span compared to healthy individuals of the same age group. According to the Michael J. Fox Foundation for Parkinsons Research, patients usually begin developing Parkinsons symptoms around age 60. Many people with PD live between 10 and 20 years after being diagnosed. However, a patients age and general health status factor into the accuracy of this estimate.
While there is no cure for Parkinsons disease, many patients are only mildly affected and need no treatment for several years after their initial diagnosis. However, PD is both chronic, meaning it persists over a long period of time, and progressive, meaning its symptoms grow worse over time. This progression occurs more quickly in some people than in others.
Pharmaceutical and surgical interventions can help manage some of the symptoms, like bradykinesia , rigidity or tremor , but not much can be done to slow the overall progression of the disease. Over time, shaking, which affects most PD patients, may begin to interfere with daily activities and ones quality of life.

How Do You Know When Your Parkinsons Has Progressed
Parkinsons changes your body gradually, and not always worsening it when it does. I once had a terribly increased tremor that would not ease. I thought I was in the next phase of the disease. Then after about a week, the tremor suddenly went away. It turns out I was going through a very intense and stressful week and my body was reacting to this stress.
The Arrow of the Disease
The direction that Parkinsons normally wants to go is to progress forward. This is what we call the arrow of the disease, where it tends to go. The arrow of Parkinsons tends to move through the various stages, from one, with minor symptoms, to two, three, and four, with moderate symptoms, and five, with severe symptoms and what we call the end stage, where being unmedicated is bad, being medicated is less bad, and having an advanced therapy like Deep Brain Stimulation or the Duopa pump makes symptoms the least bad.
How Do You Know Where Youre at?
There is a phrase in business that is taught to managers, and this phrase fits managing an illness as well. You cant manage what you dont measure. This is so true! Lets suppose you wake up one day and youre feeling bad, your meds arent working right, and you feel a little depressed and not sure why. Is this a new phase of the disease? Is this just a blip, perhaps a stressful moment in your life manifesting itself in your body as increased symptoms? How do you know?

Changes In Sleeping Patterns
As Parkinsons progresses, you can also develop problems with sleep patterns. These may not happen in the early stages, but can be noticeable later. You might wake up often in the middle of the night or sleep more during the day than you do at night.
Another common sleep disturbance for people with Parkinsons is rapid eye movement sleep behavior disorder. This is when you start acting out your dreams in your sleep, such as verbally and physically, which can get uncomfortable if someone is sharing your bed. Dr. Rundle-Gonzalez says many times a bed partner will be the one to notice sleep problems.
REM sleep behavior disorder can also happen in people who dont have Parkinsons. However, if this isnt something youve dealt with before, its likely related to your disease. There are medications your doctor can prescribe to help you sleep comfortably through the night.
Parkinson’s Disease Symptoms: Life Expectancy
Even though Parkinson’s disease is a serious, progressive condition, it is not considered a fatal illness. People who have Parkinson’s disease usually have the same average life expectancy as people without the disease.
But when the disease is in its advanced stages, Parkinson’s symptoms can lead to life-threatening complications, including:
- Falls that lead to fractured bones
- Pneumonia
- Choking
Thinking about the progression of Parkinson’s disease can be frightening. But proper treatments can help you live a full, productive life for years to come. And researchers hope to one day find ways to halt the progression of Parkinson’s and restore lost functioning.

Stage Five Of Parkinsons Disease
Stage five is the most advanced and is characterized by an inability to rise from a chair or get out of bed without help, they may have a tendency to fall when standing or turning, and they may freeze or stumble when walking.
Around-the-clock assistance is required at this stage to reduce the risk of falling and help the patient with all daily activities. At stage five, the patient may also experience hallucinations or delusions.
While the symptoms worsen over time, it is worth noting that some patients with PD never reach stage five. Also, the length of time to progress through the different stages varies from individual to individual. Not all the symptoms may occur in one individual either. For example, one person may have a tremor but balance remains intact. In addition, there are treatments available that can help at every stage of the disease. However, the earlier the diagnosis, and the earlier the stage at which the disease is diagnosed, the more effective the treatment is at alleviating symptoms.
Myth : Parkinsons Medications Cause Symptoms
Fact: Even though the myth that Parkinsons disease medicines are toxic and make the condition progress faster was completely debunked, it persists. Levodopa is the main drug therapy for Parkinsons disease. Its a potent drug that helps patients with motor symptoms. But many people got the idea that over time, it makes the disease progress faster. The myth was that levodopa is somehow toxic and is somehow making the Parkinsons progression faster, hurting patients.
This misconception was debunked decades ago with a large clinical trial, where it was found that people exposed to levodopa versus a placebo werent worse. In fact, they were better at the end of the study.
Its true that levodopa isnt a cure as yet, there is no cure for Parkinsons disease but its not toxic.

The Role Of Levodopa In Pd Gait Progression
Although the precise mechanisms of non-dopaminergic gait control are unclear, emerging evidence suggests the importance of the cholinergic system . Cholinergic neurons in the pedunculopontine nucleus influence gait and postural control , and slower walking speed in PD is associated with increases in short-latency afferent inhibition and cholinergic denervation . Also, deep brain stimulation within the PPN may improve step velocity suggesting interventions that target brain regions not primarily dependent on dopamine may therefore help to mitigate gait impairment in PD. The benefits of drugs targeting the cholinergic system on PD gait are also being explored . Overall, interpretation of the relationship between dopamine and gait progression is limited as gait was not assessed off medication, nor were biomarkers of dopaminergic activity such as DAT imaging used. Nevertheless, our findings indicate that discrete gait characteristics progress irrespective of levodopa, suggesting the importance of non-dopaminergic mechanisms in gait impairment.
