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
- 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.
How Does Parkinsons Affect The Face
Everyday tasks such as getting dressed, writing, picking something up off the floor take twice as long as they used to. Some people describe the feeling of slowness and stiffness as walking through molasses or moving in slow-motion. Because subconscious muscle movements of the face are responsible for ones facial expressions and others interpretation of our mood, patients can be thought to be upset or depressed when they are not. This is known as having a masked face.
How Parkinsons Disease Affects The Brain
What makes Parkinsons disease distinctive from other movement disorders is that cell loss occurs in a very specific region of the brain called the substantia nigra . The nerve cells, or neurons, in this region actually appear dark under a microscope .
Those dark neurons produce a specific type of neurotransmitter called dopamine. The neurotransmitter dopamine helps to regulate movement. This loss of dopamine is the reason that many treatments for Parkinsons Disease are intended to increase dopamine levels in the brain. Future research will hopefully tell us more about alpha-synuclein. Learn more about APDA research initiatives here.
In addition to decreases in dopamine and the cells that make dopamine, you might also read or hear about alpha-synuclein . We do not yet know what this protein does in the healthy brain, but in Parkinsons disease it clumps up in what are called Lewy bodies. Researchers believe that alphasynuclein build-up contributes to the cause of Parkinsons disease and that it may be possible to develop new treatments based on this idea.

Theory Of Pd Progression: Braaks Hypothesis
The current theory is that the earliest signs of Parkinson’s are found in the enteric nervous system, the medulla and the olfactory bulb, which controls sense of smell. Under this theory, Parkinson’s only progresses to the substantia nigra and cortex over time.
This theory is increasingly borne out by evidence that non-motor symptoms, such as a loss of sense of smell , sleep disorders and constipation may precede the motor features of the disease by several years. For this reason, researchers are increasingly focused on these non-motor symptoms to detect PD as early as possible and to look for ways to stop its progression.

Slice Title3 Things We Know About Parkinson’s
Parkinson’s develops when cells in the brain stop working properly and are lost over time. These brain cells produce a chemical called dopamine.
Symptoms start to appear when the brain cant make enough dopamine to control movement properly.
There are 3 main symptoms – tremor , slowness of movement and rigidity – but there are many other symptoms too.
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.
Dementia screening tests are the and the . 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.
If DLB is suspected when parkinsonism and dementia are the only presenting features, PET or SPECT imaging may show reduced dopamine transporter activity. A DLB diagnosis may be warranted if other conditions with reduced dopamine transporter uptake can be ruled out.
Since 2001, – has been used diagnostically in East Asia , but not in the United States. MIBG is taken up by nerve endings, such as those that innervate the heart, and is for scintigraphy with radioactive 123iodine. Autonomic dysfunction resulting from damage to nerves in the heart in patients with DLB is associated with lower cardiac uptake of 123I-MIBG.

Paul Gosar Illness & Health Update
Since Gosar hasnt provided many updates about his health condition, we believe he has arthritis and two compressed vertebrae in his neck and lower back. The condition will necessitate back surgery.
In addition, he had hip replacement surgery back in 2015, which was very tough for him as he suffered many after-effects from it.
Spinal experts agree that people whose jobs require bending over are more likely to develop spinal arthritis and compressed discs.
These conditions can cause limb pain, tingling, weakness, and loss of fine-motor control.
According to one expert, spasms are fairly common, but they are more rare, according to another.

Because they had not examined or treated Gosar, the doctors spoke in broad strokes.
According to the doctors, treatments may include physical therapy and stretching and medication, and surgery.
According to them, recovery from surgery can take anywhere from a few days to several weeks. Pain relievers can range from Tylenol to muscle relaxants to narcotic pain relievers like OxyContin.
Common Complications And Side
As Parkinsons disease progresses , symptoms have a knock-on effect. Deterioration and impairments in the body can lead to a variety of other health concerns that cause a person great difficulty.
As much as these potential concerns cause discomfort for a person, all are treatable with appropriate medication or therapies.
Associated complications which can arise include:
How to manage some of the more common side-effects of Parkinsons disease
The nature of Parkinsons disease progression means that the condition manifests in a variety of ways, not just in areas of mobility. Non-motor symptoms can sometimes be of more distress to a sufferer, troubling their day-to-day lives even more so than their physical ailments.
Once certain non-motor symptoms are recognised, it is easier to understand why and how they are adversely affecting quality of life, as well as gain control through appropriate treatment.
Other problems which can also be effectively managed include:

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.
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.

Living With Parkinson Disease
These measures can help you live well with Parkinson disease:
- An exercise routine can help keep muscles flexible and mobile. Exercise also releases natural brain chemicals that can improve emotional well-being.
- High protein meals can benefit your brain chemistry
- Physical, occupational, and speech therapy can help your ability to care for yourself and communicate with others
- If you or your family has questions about Parkinson disease, want information about treatment, or need to find support, you can contact the American Parkinson Disease Association.
A Note For Caregivers
Caregivers can be challenged by the increasing needs of a declining Parkinson’s patient. It is important that caregivers have a good concept of this progressive disease. Support groups are available to help caregivers understand the disease process and how to cope with the various problems they face in caring for a Parkinson’s disease patient.

language, called Wernickes aphasia. Cerebral palsy is a broad term for brain damage sustained close to birth that permanently affects motor function. The damage may take place either in the developing fetus, during birth, or just after birth and is the result of the faulty development or breaking down of motor pathways. Cerebral palsy is non-progressive that is, it does not worsen with time. During childhood development, the brain is particularly susceptible to damage because of the rapid growth
How Is Parkinsons Disease Diagnosed
Diagnosing Parkinsons disease is sometimes difficult, since early symptoms can mimic other disorders and there are no specific blood or other laboratory tests to diagnose the disease. Imaging tests, such as CT or MRI scans, may be used to rule out other disorders that cause similar symptoms.
To diagnose Parkinsons disease, you will be asked about your medical history and family history of neurologic disorders as well as your current symptoms, medications and possible exposure to toxins. Your doctor will look for signs of tremor and muscle rigidity, watch you walk, check your posture and coordination and look for slowness of movement.
If you think you may have Parkinsons disease, you should probably see a neurologist, preferably a movement disorders-trained neurologist. The treatment decisions made early in the illness can affect the long-term success of the treatment.

Parkinsons Disease And Alcohol: Your Guide
If you have Parkinsons disease , you may be wondering whether alcohol consumption affects the development or progression of your condition. Some people may wonder if they should avoid drinking completely. As one MyParkinsonsTeam member asked, How does alcohol affect Parkinsons how much can I drink? Or should I avoid drinking altogether?
Some studies havent found that small amounts of alcohol are associated with a higher PD risk, while others highlight the dangers alcohol can pose for anyone with a chronic condition. In addition, there may be adverse interactions between alcohol and common Parkinsons medications. Because of conflicting information, people with PD may feel confused about whether or not to drink.
Ive been told by more than one doctor that I should not have any alcohol, one MyParkinsonsTeam member wrote. And at this point, I dont remember which doctor or specifically why.
So, how do you decide what approach to take?
If you have Parkinsons disease and are trying to decide whether or not to reduce your drinking or quit alcohol completely here are some things to consider.
How Is A Diagnosis Made
Because other conditions and medications mimic the symptoms of PD, getting an accurate diagnosis from a physician is important. No single test can confirm a diagnosis of PD, because the symptoms vary from person to person. A thorough history and physical exam should be enough for a diagnosis to be made. Other conditions that have Parkinsons-like symptoms include Parkinsons plus, essential tremor, progressive supranuclear palsy, multi-system atrophy, dystonia, and normal pressure hydrocephalus.

Surgical Treatment For Parkinsons
This is advised when the disease progresses and the medications are no longer controlling the symptoms of PD adequately.
- As the disease progresses, Levodopa still works, but the brains response to the medication becomes less predictable. Levodopa may take longer to kick in and may wear off earlier, requiring patients to take medication more frequently during the day. Higher doses of levodopa are associated with abnormal involuntary movements, known as dyskinesias . Unpredictable medication effect results in OFF time when patients feel stiff, rigid, stuck, frozen, slow, or fatigued, compared to ON time when movements are smooth and closer to normal.
- Treatment options as the disease progresses include taking levodopa more frequently making the medication last longer by adding medications to reduce the metabolism of levodopa, or dopamine adding or changing to long-acting forms of levodopa , or adding or changing to long-acting forms of dopamine agonist . Amantadine can be added to reduce dyskinesia. As these options are being considered and implemented, its time to consider deep brain stimulation surgery .
- Deep brain stimulation surgery is FDA-approved for the treatment of motor complications in Parkinsons disease and is not experimental. DBS is not a last-resort treatment. It has been shown that DBS is more beneficial when performed earlier in the course of the disease compared to waiting for disability.
What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.
