When People Talk About Parkinsons They May Mention The Effects It Has On The Substantia Nigra But Did You Know That There Are Other Areas Of The Brain That Are Affected By The Condition
Parkinson’s is a condition that causes the gradual loss of the dopamine-producing brain cells of the substantia nigra — an area of the brain located just above where the spinal cord meets the midbrain. It is these cells that produce and release the neurotransmitter dopamine, which has a key role in turning thought about movement into action.
While this definition of the condition is useful to briefly explain Parkinson’s, the whole story is somewhat more complex. Over the last 30 years, it has become accepted that Parkinson’s also causes a number of non-motor symptoms, such as changes in sleep, smell and even the way we think, which likely involve other areas of the brain.
Now scientists are looking at the broader effects of the condition on the brain in an attempt to better understand why people experience different symptoms. The finding could lead us to new treatments that tackle more than just the motor symptoms of the condition.
Australian Researchers Hope Brain Gel Can Reverse Parkinsons Disease Symptoms Voa Asia 0

Australian researchers say they have developed a new type of gel that could radically transform the treatment of Parkinson’s disease and could also help stroke patients.
The hydrogel is made from natural amino acids, the building blocks of proteins, and has been shown to safely deliver replacement cells into damaged parts of the brain.
The gel acts as a vehicle to safely transfer stem cells into the brain. Scientists believe the process can restore damaged tissue and replace lost neurons, which affect patients with Parkinson’s disease, a nervous system disorder. About 100,000 Australians are estimated to suffer from the disease, which currently has no cure.
Spinal Cord Stimulation Found To Reduce Pain Motor Symptoms In Parkinson Disease Matthew Gavidia
Spinal cord stimulation was found to decrease pain and reduce motor symptoms of Parkinson disease as both a singular therapy and as a salvage therapy after deep brain stimulation therapies proved ineffective.
The current gold standard of treatment for Parkinson disease includes dopamine and deep brain stimulation therapy, but researchers of a study published this week in Bioelectronic Medicine note that both approaches have their limitations and reported adverse effects. Moreover, they also have been shown to lose efficacy over time.
Along with dopamine and DBS, spinal cord stimulation has emerged as an alternate therapy linked with alleviating both motor and nonmotor symptoms, such as pain, in PD.
“Whether to use SCS as a singular bioelectric therapy option or as a salvage therapy after dopamine and DBS treatments have begun to lose efficacy continues to be a question of interest,” said the study authors.
The researchers examined the use of SCS for the treatment of pain and motor symptoms in 15 patients with PD, as both a singular bioelectric therapy and as a salvage therapy after DBS. The study cohort had experienced pain not alleviated by prior treatment, with 8 having undergone DBS pain therapy and 7 having received only drug treatments.
In the study, the researchers implanted percutaneous electrodes through the skin of participants at the level of the thoracic or cervical spine. Each participant was set to 1 of 3 stimulation modes:
Diagnosis Of Dementia With Lewy Bodies And Parkinson Disease Dementia
Doctors base the diagnosis of dementia with Lewy bodies on its characteristic symptoms. Dementia with Lewy bodies is likely if mental function fluctuates in people who have visual hallucinations and muscle and movement symptoms similar to those caused by Parkinson disease.
Computed tomography and/or magnetic resonance imaging may be done to rule out other causes of dementia.
Other imaging tests may help doctors diagnose dementia with Lewy bodies. They include positron emission tomography and single-photon emission CT . These tests use a substance containing a radioactive tracer that, when injected into a vein, collects in a particular organ. A gamma-ray camera attached to a computer detects the radioactivity, and the computer produces an image of the organ being examined.
However, even after testing, distinguishing dementia with Lewy bodies from Parkinson disease dementia can be difficult because symptoms are similar:
Generally, dementia with Lewy bodies is more likely if movement and muscle problems develop at the same time or shortly after mental function starts to decline.
Parkinson disease dementia is more likely if mental decline occurs years after muscle and movement problems develop in people with Parkinson disease and if muscle and movement symptoms are more severe than mental impairment.

The Use Of Nano Structured Neural Scaffolds For Neural Regeneration
Topical ReviewUse of nano-structured neural scaffolds for neural regeneration in case of Parkinson’s DiseaseABSTRACTParkinson’s Disease affects a large percentage of people all over the world. Currently, an effective strategy for regeneration of neurons that are lost in PD does not exist; however, nanotechnology has offered new avenues in the field of neural tissue regeneration. Nanostructured scaffolds have been shown to have the ability to promote neuronal growth and their excellent biomimetic
Pain Is An Unfortunately Common Problem In Parkinsons Disease
Of course, pain is common in the general population, especially among older people. A recent American study found that pain affected about twice as many people with Parkinson’s Disease than those of the same age and gender without PD. About 50% of Parkinson’s Disease patients in that study suffered from painful disorders. Men and women seem to be about equally affected. A very well described scenario is the patient who is followed for a painful frozen shoulder for a year or so before a tremor develops leading to a diagnosis of PD. Pain clearly plays a major role in quality of life. Everyone with chronic pain enjoys life less, leading to a vicious cycle in which pain causes depression or isolation which in turn leads to more pain.
Parkinson patients suffer from the same pain problems that other people have, often amplified by the motor dysfunction, but they also have additional pain problems which are unique to PD.
One recent review classified the types of pain Parkinson’s Disease patients have into: musculoskeletal, in which the pain results from problems with the muscles , bones or joints; dystonic, which is due to abnormal muscle contractions caused by the Parkinson’s Disease or the medications used to treat it; radicular pain, which is feels like the pain caused by pinched nerves; central pain, which is presumed due to abnormalities in the brain, and is a continuously present pain that cannot be explained otherwise; and discomfort related to an unpleasant urge to move.
What Causes Pain In Cases Of Parkinsons Syndrome Sufferers
Parkinson’s Syndrome Sufferers may present with various combinations of back, buttock and leg pain, numbness and muscle weakness, Symptoms are often aggravated by an abnormal asymmetrical gait arising from loss of spatial awareness muscle spasm and loss of limb control. The back pain may arise from irritation within the disc wall but more commonly arises from the pinching of the trapped nerve in the exit doorway from the spinal column. The foramen may be distorted and the nerve is tethered by years of scarring reaction to repetitive bruising, can not evade the pinching by the bulging distorted disc wall or overriding facet joints . The disc may be degenerate and bulging and contribute to the irritation of the tethered nerve. When advanced the compression causes numbness and weakness to develop. The patchy weakness or spasm of the muscles controlling the spinal segments results in asymmetrical loss of control or stiffness of the disc levels and aggravation of the effects of the local pathology at each level and aggravation of symptoms arising at these levels.
The Preponderance Of Injury In The Past Of People With Pd
Neck issues or damage can be caused by injuries, but the injury site doesn’t have to be local to the neck itself, since it is an integral part of the kinetic chain of the human body – problems anywhere else which affect posture can, in turn, profoundly affect how we tense our necks and cause strains on it by the way we are holding up the head. I’ve frequently asked people with Parkinson’s Disease to think carefully about any pains and injuries which they might have incurred either before or concurrent with their PD diagnosis. I’ve found that the overwhelming majority of us have suffered a prior accident or physical trauma. Injuries to jaw, neck, shoulders, back, hips, knees or feet predominate. All these severely affect posture and hence the kinetic chain and are liable to make our necks prone to permanent strains and stiffness. So in my view, even if chemical “cures” were invented tomorrow, people with PD would still present with the postural problems, still suffer from the old injuries which have been masked by the narratives of neurology, and would probably quickly decline into pain and problems again, unless these past injuries are properly attended to.
Lower Back Pain And Back Of The Neck Pain Are Most Common
Pain occurs for a number of reasons and it’s not always clear what the cause is, making it difficult to figure out how best to treat it. I believe that most common pain problems in Parkinson’s Disease are the same as in the general population, but amplified. Low back pain and back of the neck pain are probably the most common pain conditions in PD. The reason Parkinson’s Disease patients have so many problems with their low back and their neck is their posture. Parkinson’s Disease causes a stooped posture. Some of this happens with age anyway, particularly in women after menopause when their bones soften, but is always worse from the PD. All Parkinson’s Disease patients have some degree of stooped posture and many also tilt to one side. Because of the stooped posture, the muscles in the lower back have to pull much harder to keep the spine upright.

Dementia with Lewy bodiesParkinson disease dementia
People who have dementia with Lewy bodies fluctuate between alertness and drowsiness and may have hallucinations, difficulty drawing, and difficulty moving that is similar to that due to Parkinson disease.
Parkinson disease dementia typically develops about 10 to 15 years after other symptoms of Parkinson disease.
Diagnosis is based on symptoms.
Strategies are used to prolong functioning as long as possible, and the drugs used to treat Alzheimer disease may help.
Dementia with Lewy bodies is the third most common type of dementia. Dementia with Lewy bodies usually develops in people older than 60.
About 40% of people with Parkinson disease develop Parkinson disease dementia. The dementia usually develops after age 70 and about 10 to 15 years after Parkinson disease is diagnosed.
Dementia is a slow, progressive decline in mental function including memory, thinking, judgment, and the ability to learn.
Dementia differs from delirium, which is characterized by an inability to pay attention, disorientation, an inability to think clearly, and fluctuations in the level of alertness.
Dementia affects mainly memory, and delirium affects mainly attention.
Dementia typically begins gradually and has no definite beginning point. Delirium begins suddenly and often has a definite beginning point.
Parkinson’s is a degenerative disorder of the central nervous system. It is caused by the loss of nerve cells, which contain a chemical called dopamine. Many people understand Parkinson’s Disease to only cause delayed movement and impaired balance.In reality, Parkinson’s Disease is much more complex. It can affect a person’s ability to do things people take for granted. One of the key problems people with Parkinson’s can experience is incontinence. Studies have shown prevalence statistics ranging from 27% to 85% for urinary symptoms in Parkinson’s patients.
Strengthening Exercises Or Stretching May Be Helpful
Imagine that the spine is like a telephone pole or the mast of a sailboat. If the pole is not exactly upright, even a slight tilt requires a great force to keep it from tilting further and falling. In the human body, this means that the lower back muscles are under great stress. It also means that the tension on the back bones is much increased as well. This worsens whatever problems, like arthritis, that are already present. The same process applies to the neck, although the forces are less great. Strengthening exercises or stretching may be helpful. Almost everyone over the age of 60 has arthritis in their spine. Luckily most don’t have pain from it, but those who do will have it worsened by the spine curvature caused by the PD.
PD patients also frequently have an aching discomfort in their muscles, particularly in the thighs and shoulders. I think this is due to the rigidity, or stiffness, that is part of the Parkinson’s Disease syndrome, but I’ve seen many patients with this pain and no apparent stiffness on examination, hence not explained. It is common and it often, but not always, responds to alterations of the usual Parkinson’s Disease medications for movement. Exercise and stretching may be helpful as well and should always be tried first before increasing medications.
Pain is a challenge in PD. We can’t measure it and often cannot find its cause. It is, however, often treatable, and reducing pain improves quality of life.
Schizophreni Symptoms And Devastating Mental Disease
the two Greek words “skhizo” and “phren” . The term was first coined in 1908 by a Swiss psychiatrist Eugen Bleuler. Schizophrenia is probably the most tragic, enigmatic and devastating mental disease that physiatric APN treat in their practices. Schizophrenia is a mental disease that is diagnosed in the early years of the patient that is inflicted by it. One of the many puzzling characteristics of schizophrenia is that men generally suffer from the mental illness more severely than
What Is Special About Parkinsons Syndrome Sufferers
Parkinson’s Syndrome is a condition where the important nuclei below the brain become dysfunctional resulting in impaired communication and transmission of nerve impulses to and from nerve fibres throughout the body. Consequently some cognitive processes, eyesight focus, muscle control or strength may deteriorate. This often presents in a haphazard fashion with increasing stiffness of the joints and muscles and intention tremor most noticeable in the hands. Fine movements and writing ability deteriorate, The gait deteriorates as seem as a shuffling pattern with small steps with a quickening of gait as power is mustered and spasm is overcome, Whilst there is a downhill trend the process of deterioration may arrest for periods.
Seldom does this process directly generate nerve pain such as sciatica. Back or Neck pain and pain referred in to the arm or leg may arise in Parkinson’s Syndrome Sufferers as part of the Degenerative Disc Disease seen in the rest of the population and with the same pathologies; disc protrusions, nerve entrapment / scarring / tethering, Lateral Recess Stenosis, Axial Stenosis, Spondylolytic Spondylolisthesis, vertebral slippage, “Instability”, Failed Back Surgery or failed chronic pain management.
The Use Of Levodopa And Peripheral Neuropathy
There are reports in the literature that levodopa use may increase the risk of peripheral neuropathy, although other studies suggest that this is not the case. There are studies that demonstrate for example, that cumulative Levodopa exposure correlates to prevalence of PN in people with PD. Other studies however, demonstrate no difference in the prevalence of PN whether the person was treated with Levodopa or not, suggesting that Levodopa treatment does not play a role in development of PN.
Another area of research that emerges from the literature is the potential role of Vitamin B12 deficiency in the development of PN in those with PD. Some studies suggest that Vitamin B12 deficiency is a more common cause of PN among those with PD than those with PN who do not have PD.
There is also research that suggests that levodopa treatment may contribute to PN through impairment of Vitamin B12 metabolism, leading to Vitamin B12 deficiency. Taking COMT inhibitors such as Entacapone may protect against this complication.
Regardless, if PN is diagnosed in anyone, whether they have PD or not, and whether they take Levodopa or not, Vitamin B12 and various other markers of Vitamin B12 metabolism should be tested. If Vitamin B12 levels are low or even low-normal, a person should take Vitamin B12 supplementation, which may help with the symptoms of PN. Other causes of PN, many of which can be checked with various blood tests, should be investigated as well.
How Can Parkinsons Disease Cause Incontinence
Individuals with Parkinson’s Disease can develop incontinence when the communication between the brain and the bladder becomes faulty. The bladder is a muscle that expands gradually as urine collects. At the opening of the bladder, there is a muscle called the sphincter. This muscle is usually closed except during urination. The brain controls both the bladder and the sphincter muscle. Under normal circumstances, the bladder begins to have small contractions that alarm the brain when 1-2 cups have been collected in the bladder. In Parkinson’s Disease, however, the brain lacks complete control over the sphincter. Parkinson’s disease attacks the brain, focusing on dopamine-producing cells. These cells are vital in maintaining brain health, as they deal with signals controlling muscle movement. In patients with Parkinson’s disease, the bladder becomes overactive and has unwanted contractions which can be impossible to stop. This miscommunication and lack of control can cause a person with Parkinson’s Disease to feel the need to empty their bladder even when there is just a small amount of urine present. Sufferers can also often find themselves finding it difficult to eliminate urine.
Parkinson’s Disease can affect the brain and spinal cord
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.

Peripheral Neuropathy And Parkinsons Disease
A number of studies have tried to determine if PN is more common among people with PD as opposed to people without PD. PN is a relatively common condition in the general population, which makes it difficult to ascertain whether or not it is even more common among people with PD.
The available studies have varying results and are difficult to compare with each other as they:
- Include different types of populations of people with PD
- Assess peripheral neuropathy differently
- Assess for causes of peripheral neuropathy differently
A recent review looked at all the available data and determined that large fiber neuropathy was present in 16% of patients with PD, about double the prevalence of this condition in the general population. Skin biopsy-proven small fiber neuropathy was present in over 50% of people with PD, although this result was based on a small sample of patients.
Impact Of Parkinsons Disease On Spinal Cord
Parkinson’s disease is a degenerative disease associated with progressive nerve disorders. It affects two specific regions of the central nervous system – the brain and the spinal cord.Parkinson’s disease on spinal cord cause primary motor symptoms like
- Tremors even on resting muscles
- Stiffness and rigidity due to increased muscle tone
- Slowness of physical movements
- Postural instability issues due to impaired balance and coordination
Additionally, there may be secondary motor symptoms like fatigue, involuntary movements, speech problems, handwriting variations and swallowing difficulties. In severe cases, PD impacts the thinking process and causes dementia in many patients.
Causes of PD
PD is caused by the destruction or degeneration of certain brain nerve cells called dopaminergic cells. These cells produce dopamine, a neurotransmitter, which aids in transmitting messages for controlling and coordinating body movements. In PD cases, there is a decline in dopamine production. This in turn makes it harder for the brain and spinal cord to control and coordinate muscle movements.
Risk Factors for PD
There also seems to be a relation between Spinal Cord Injury and Parkinson’s disease . Some research studies have found out that patients who have SCI are at an increased risk of PD.
Treatment of PD
Impact of Parkinson’s disease
PD impacts various body functions and interferes with daily life tasks. PD complications include
Is Accurately Targeted Treatment Possible
Single targeted surgery enables Parkinson’s Syndrome Sufferers to be precisely treated with the minimum of damage to tissues, reduced patient risk and enhanced long-term outcome and more essentially without the use of General Anaesthesia. This treatment, which is called ‘Foraminoplasty’ because it is carried out in the gaps or ‘Foramen’ between the vertebrae, allows the nerve to thoroughly liberated and the overriding joints or pointed fracture margins to be removed. This is only possible by the use of Endoscopic Minimally Invasive Spine Surgery where the full length of the exiting nerve can be explored and the points of irritation clearly demonstrated. In the breadth of presentations arising from Degenerative Disc Disease and Failed Back Surgery or Failed Chronic Pain management, Endoscopic Lumbar Decompression & Foraminoplasty achieved a successful enduring positive outcome in 80% of cases.
Care For Patients With Parkinsons Disease
While health and quality of life deteriorate dramatically, Parkinson’s does not appear to shorten a person’s lifespan. Thus, the focus of care is on slowing progression of the disease and maintaining quality of life and independence for the patient for as long as possible.
Since it affects the central nervous system primarily, keeping this part of the body functioning optimally is a must. Let’s look at three ways upper cervical chiropractic may be able to help maintain proper CNS function.

Neurobehavioral And Psychiatric Disorders
Parkinson’s disease is a slowly progressing, degenerative disease that is the most common form of Parkinsonism, a group of motor system disorders.
For some time it was incorrectly believed that Parkinson’s disease disappeared after the introduction of levodopa in the 1960s. In fact, about 50,000 Americans are diagnosed with Parkinson’s disease each year, with more than half a million Americans affected at any one time. Further, more people suffer from Parkinson’s disease than multiple sclerosis, muscular dystrophy, and amyotrophic lateral sclerosis combined.
Parkinson’s disease is chronic , and progressive .
Although the disease may appear in younger patients , it usually affects people in late middle age. The disease affects men and women in almost equal numbers. It is not contagious, nor is it likely passed on from generation to generation.
What Is Wrong With Conventional Surgery
The use of multi-level open surgery in Parkinson’s Syndrome Sufferers including microdiscectomy, decompression, solid or flexible fusion and is an ‘overkill’ with negative side-effects including blood loss, potential nerve and tissue damage, extended post-operative care and unnecessarily operating on pain-free levels is fraught with aggravation of the current symptom status. It is not as effective as Foraminoplasty in addressing and ameliorating the effects of Parkinson’s Syndrome Sufferers, rather it runs the risk of increased neurological complications as well as causing the complications of recurrent disc bulging, infection, nerve damage and scarring round the nerve, implant failure, major vessel damage or sexual dysfunction.
How Does Parkinson’s Affect The Bladder
April 11 2020
In the second out of two posts, we explore how Parkinson’s Disease affects bladder and bowel function, and hear from those who eventually found effective ways to manage their symptoms.Bladder difficulties are common when you have Parkinson’s disease, particularly in the later stages of the condition. The symptoms differ from person to person, but the most common are:
We spoke to Mary and Jerry, who both have Parkinson’s disease. In these excerpts from our free guides – Bladder and Bowel dysfunction when you have Parkinson’s Disease, they describe how the progression of the disease led them to seek out effective bladder management routines.
To learn more about how Parkinson’s affects bladder and bowel function, and effective therapies for managing these symptoms and functions, we’ve made these free guides available for download.
Female and male anatomy are different, and the effects of Parkinson’s disease may have different effects when it comes to bladder and bowel dysfunction.
The bladder and bowel also interact and effect the functioning of these processes. In these free guides, we look at the symptoms, effects and therapies available to manage this condition.
Bladder and Bowel dysfunction when you have Parkinson’s Disease
Complementary And Alternative Therapies
Some people with Parkinson’s disease find complementary therapies help them feel better. Many complementary treatments and therapies claim to ease the symptoms of Parkinson’s disease.
However, there’s no clinical evidence they’re effective in controlling the symptoms of Parkinson’s disease.
Most people think complementary treatments have no harmful effects. However, some can be harmful and they shouldn’t be used instead of the medicines prescribed by your doctor.
Some types of herbal remedies, such as St John’s wort, can interact unpredictably if taken with some types of medication used to treat Parkinson’s disease.
If you’re considering using an alternative treatment along with your prescribed medicines, check with your care team first.

Relief From Pain And Improved Mobility
The researchers observed that the 15 patients experienced “significant improvement” after using the spinal cord stimulator device.
Based on the visual analog scale of pain intensity — the seven patients who had never received DBS experienced a 57% reduction, on average. For those who had received DBS in the past, the average reduction in pain intensity was 61%.
In addition, the researchers found that participants who opted for the cycling mode experienced, on average, a 67% reduction pain, using the same scale. By comparison, those who chose continuous burst stimulation had, on average, a 48% reduction in their pain scores.
Of the 15 patients, 11 had been able to complete a 10-meter walk before and after the study. After the stimulation, eight people in this group showed an average improvement of 12% during their 10-meter walks. The researchers used these walks to assess the participants’ mobility and gait.
They also used a “timed up-and-go” test to measure how long it takes a person to get up from a chair, walk 3 meters, turn around, walk back to the chair, and sit down. Among the 11 participants who completed this test, seven showed improvement in their completion times.
The patients who chose a continuous burst pattern had an 18% improvement in their timed up-and-go scores. However, those who chose the cycling mode had a 7% worsening in these scores.
The team of researchers, based in the U.S. and Japan, observe:
