Final Conclusions/practical Algorithm For Management
Dysfunction of the upper GIT in PD, especially oropharyngeal dysphagia, are complex syndromes occurring early in disease that often remain unnoticed until severe complications, such as aspiration pneumonia, become manifest. In the lower GIT, constipation is a widespread and debilitating symptom with the potential of leading to severe bowel complications and even cognitive dysfunction.
In closing, standardized and early diagnostic approaches together with continuous and long-term treatment are necessary to help patients .
What Tests Will Be Done To Diagnose This Condition
When healthcare providers suspect Parkinsons disease or need to rule out other conditions, various imaging and diagnostic tests are possible. These include:
New lab tests are possible
Researchers have found possible ways to test for possible indicators or Parkinsons disease. Both of these new tests involve the alpha-synuclein protein but test for it in new, unusual ways. While these tests cant tell you what conditions you have because of misfolded alpha-synuclein proteins, that information can still help your provider make a diagnosis.
The two tests use the following methods.
- Spinal tap. One of these tests looks for misfolded alpha-synuclein proteins in cerebrospinal fluid, which is the fluid that surrounds your brain and spinal cord. This test involves a spinal tap , where a healthcare provider inserts a needle into your spinal canal to collect some cerebrospinal fluid for testing.
- Skin biopsy. Another possible test involves a biopsy of surface nerve tissue. A biopsy includes collecting a small sample of your skin, including the nerves in the skin. The samples come from a spot on your back and two spots on your leg. Analyzing the samples can help determine if your alpha-synuclein has a certain kind of malfunction that could increase the risk of developing Parkinsons disease.
Considerations For The Inpatient Management Of Parkinsons Disease
Recognising and managing certain complications of Parkinsons disease can help improve care and reduce the risk of admission for people living with the condition.

Parkinsons disease is a neurological disorder in which there is progressive death of dopaminergic neurones in the substantia nigra the part of the mid-brain responsible for managing movement and the dopaminergic system with more than 50% of cell death occurring before symptom manifestation. The subsequent deficiency of dopamine synthesis, owing to this cell death, leads to the progression of motor symptoms including bradykinesia, rigidity, tremor and postural instability,.
Around 137,000 people in the UK have a PD diagnosis. The cause of the disease is yet to be discovered, but a combination of environmental and genetic factors are thought to increase its risk. Despite this, there is a lack of robust, large-scale evidence of a definitive link between any specific environmental risk factors. Around 20% of patients affected by PD have a first-degree relative that is affected by the disease. Prevalence is higher with increasing age and men appear to be at higher risk of developing the disease than women,. Patients with PD have a reduced life expectancy and studies have suggested up to a five-times higher mortality rate than people in the same age group without PD.

Parkinson’s Disease: Treatment Is Best Started Early
by Emily Henderson, The Conversation
BBC broadcaster Jeremy Paxman was brought to hospital after he collapsed in a park while walking his dog. A doctor in the emergency department said to Paxman: “I think you have Parkinson’s.”
The doctor had noticed that Paxman was less animated than usual when presenting University Challenge. A mask-like face is a classic symptom of the disease.
Paxman said the diagnosis was “completely out of the blue.”
In Parkinson’s disease, there is a loss of a chemical in the brain called dopamine that causes movements to be smaller and slower. In the early stages of the disease, people notice that their walking slows and they have difficulty keeping pace with companions.
Sometimes people find it difficult to turn over in bed or have trouble with more awkward tasks, such as doing up buttons. Balance and stability can also be affected, which can put people with the condition at higher risk of fallsas happened to Paxman.
A diagnosis is primarily made through listening to the symptoms that someone describes. Doctors also conduct bedside tests that look for slow and small movements of the hands, arms and legs as well as shaking and stiffness of the muscles. Imaging scans can play a role in helping exclude other causes of movement difficulties. It is important to exclude the changes in movement being caused by some medications or by hardening of the arteries of the brain that happen as people get older.

Parkinsons Disease Is A Neurodegenerative Condition
Parkinsons disease is a chronic condition in which neurons within a region of the brain responsible for the control of movement break down and die. These neuronal cells use a chemical called dopamine to communicate with each other. It is this complex dopamine-based communication between neurons that is responsible for control of movement. Death of these neurons is referred to as dopaminergic neurodegeneration, and directly leads to the movement-related symptoms of the condition . These include tremors, changes in posture, stiffness, and a slowness of movement, also referred to as bradykinesia.1,2
Importantly, and often little appreciated, is the fact that Parkinsons disease can also affect neurons outside of the brain. Neuronal connections are made throughout the body, and connect all parts of the body to the brain and spinal cord, including to the GI tract. In particular, Parkinsons interferes with normal communication between the central nervous system, and the esophagus and stomach.3 Parkinsons can also affect the enteric nervous system, a network of neurons that functions with a considerable level of independence from the brain and central nervous system, and that is highly involved in controlling the intestinal tract and digestion.3,4 By affecting both the central and enteric nervous systems, Parkinsons disease may give rise to an array of GI symptoms.
Parkinsons Disease And The Gut
Parkinsons disease is primarily a neurological condition however, symptoms also manifest outside of the brain itself, including within the gut . This article aims to provide a simple background to Parkinsons disease, and some insights into how these GI symptoms may arise and how we can treat them. Increased awareness of these often-overlooked GI issues in Parkinsons might lead to better understanding of the condition by researchers, as well as improved treatment and quality of life for patients.

New Medications For Off Time
A number of new medications approved recently are designed to reduce OFF time. These medications fall into two major categories:
- Medications that lengthen the effect of a carbidopa/levodopa dose
- Medications that are used as needed if medication effects wear off
Well give specific examples below. In general, new medications that extend the length of a carbidopa/levodopa dose are used if OFF time is somewhat predictable and occurs prior to next dose. New medications that are used as needed are most beneficial when OFF time is not predictable.
New medications that lengthen the effect of a dose of carbidopa/levodopa
- Istradefylline is an adenosine A2A receptor antagonist which was approved in the US in 2019 as an add-on therapy to levodopa for treatment of OFF time in PD. Unlike many of the other medications, it has a novel mechanism of action and is the first medication in its class to be approved for PD. It acts on the adenosine receptor, which modulates the dopaminergic system, but is not directly dopaminergic. The drug was developed in Japan and underwent clinical trials both in Japan and in the US.
- Opicapone is a catechol-O-methyltransferase inhibitor that is taken once a day. It was approved in the US in 2020 as an add-on therapy to levodopa for motor fluctuations.

Light Therapy And Parkinsons Disease
Light therapy, or the use of light as a treatment for disease, is being investigated in many neurologic conditions including as a treatment for some of the symptoms of Parkinsons disease . Light therapy encompasses a large category of treatments involving different types of light and delivery systems. More research still needs to be done to figure out exactly what type of light therapy works for which symptoms of PD.
To better understand what we do and do not know about light therapy for PD, this week I will explore:
- What are the variables to consider when thinking about light therapy?
- Which symptoms of PD may experience relief with light therapy?
- Are there any currently available devices for light therapy to treat PD symptoms?
- What clinical trial data supports the use of light therapy in PD?
- Are there current light therapy clinical trials that are enrolling people with PD?
- Why might light therapy be helpful in PD?

Is Parkinsons Disease Inherited
Scientists have discovered gene mutations that are associated with Parkinsons disease.
There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.
Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.
Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.
How Is Parkinsons Disease Treated
There is no cure for Parkinsons disease. However, medications and other treatments can help relieve some of your symptoms. Exercise can help your Parkinsons symptoms significantly. In addition, physical therapy, occupational therapy and speech-language therapy can help with walking and balance problems, eating and swallowing challenges and speech problems. Surgery is an option for some patients.

The Gastrointestinal Effects Of Parkinsons Disease
Surveys show that between 20% and 40% of people with Parkinsons disease suffer from serious constipation . Larger numbers of people with PD have related gastrointestinal issues such as bloating, a feeling of fullness and nausea. As the disease progresses, all of these GI problems become more common. In rare cases, serious complicationssuch as megacolon and perforation or tearing of the colonmay arise from these GI problems.
The connection between the two may seem odd on the surface, but research shines some light on these unpleasant consequences of the disease.
A large survey of healthy people who were followed over several years revealed that men who reported having less than one bowel movement daily had a 2 to 7 times higher risk of developing PD than that of men who had daily bowel movements their risk was four times higher than that of men who had two or more bowel movements a day.
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.

Changes In Cognition And Parkinsons Disease
Some people with Parkinsons may experience changes in their cognitive function, including problems with memory, attention, and the ability to plan and accomplish tasks. Stress, depression, and some medications may also contribute to these changes in cognition.
Over time, as the disease progresses, some people may develop dementia and be diagnosed with Parkinsons dementia, a type of Lewy body dementia. People with Parkinsons dementia may have severe memory and thinking problems that affect daily living.
Talk with your doctor if you or a loved one is diagnosed with Parkinsons disease and is experiencing problems with thinking or memory.
Can Parkinsons Disease Be Prevented
Unfortunately, no. Parkinsons disease is long-term disease that worsens over time. Although there is no way to prevent or cure the disease , medications may significantly relieve your symptoms. In some patients especially those with later-stage disease, surgery to improve symptoms may be an option.

Clinical Trials Of White Light:
Bright vs dim light
Bright light therapy is being compared to dim red-light therapy delivered twice daily. Outcome measures include an assessment of excessive daytime sleepiness and a general scale of non-motor symptoms in PD.
SunRay light boxes
This trial will also compare bright white vs. dim red light stimulation, with light to be administered via the SunRay light box. Outcome measures include assessment of sleep and fatigue.
DayVia lamp
This trial will compare bright light vs control light. The outcome measures will be United Parkinson Disease Rating Scale scores.
Within the DB RCT for Specialized Phototherapy trial, double-blinded and randomized comparing the Celeste device to a control light. PDQ 39, a measurement of quality of life, will be the primary outcome measure. Other endpoints will be UPDRS scores of motor and non-motor symptoms. This trial has not started yet.
What Should I Do If I Forget A Dose
Take the missed dose of the regular tablet, orally disintegrating tablet, extended-release tablet, or extended-release capsule as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
If you are using levodopa and carbidopa enteral infusion and will be disconnecting the infusion pump for a short time , other than the normal nightly disconnection, ask your doctor if you should use an extra dose before you disconnect the pump. If the infusion pump will be disconnected for longer than 2 hours, call your doctor you probably will be advised to take levodopa and carbidopa by mouth while you are not using the suspension.

Medicines For Parkinsons Disease
Medicines can help treat the symptoms of Parkinsons by:
- Increasing the level of dopamine in the brain
- Having an effect on other brain chemicals, such as neurotransmitters, which transfer information between brain cells
- Helping control non-movement symptoms
The main therapy for Parkinsons is levodopa. 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 therapy such as nausea, vomiting, low blood pressure, and restlessness and reduces the amount of levodopa needed to improve symptoms.
People living with Parkinsons disease should never stop taking levodopa without telling their doctor. Suddenly stopping the drug may have serious side effects, like being unable to move or having difficulty breathing.
The doctor may prescribe other medicines to treat Parkinsons symptoms, including:
- Dopamine agonists to stimulate the production of dopamine in the brain
- Enzyme inhibitors to increase the amount of dopamine by slowing down the enzymes that break down dopamine in the brain
- Amantadine to help reduce involuntary movements
- Anticholinergic drugs to reduce tremors and muscle rigidity
Prognosis In Parkinsons Disease
Although Parkinsons disease cannot be completely cured, awell-designed treatment regimen can allow a patient to live long enough. Thereare cases when people with Parkinsons disease lived to a ripe old age. In rarecases, surgery is indicated to determine the exact location of the damaged areaof the brain that is causing the symptoms.
In the United States, the total number of patients with thisdisease is one million.

Symptoms Of Parkinsons Disease
Parkinsons has four main symptoms:
- Tremor in hands, arms, legs, jaw, or head
- Muscle stiffness, where muscle remains contracted for a long time
- Slowness of movement
- Impaired balance and coordination, sometimes leading to falls
Other symptoms may include:
The symptoms of Parkinsons and the rate of progression differ among individuals. Early symptoms of this disease are subtle and occur gradually. For example, people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly, or that their handwriting is slow and looks cramped or small. Friends or family members may be the first to notice changes in someone with early Parkinsons. They may see that the persons face lacks expression and animation, or that the person does not move an arm or leg normally.
People with Parkinson’s disease often develop a parkinsonian gait that includes a tendency to lean forward take small, quick steps and reduce swinging their arms. They also may have trouble initiating or continuing movement.
Symptoms often begin on one side of the body or even in one limb on one side of the body. As the disease progresses, it eventually affects both sides. However, the symptoms may still be more severe on one side than on the other.
