To identify whether the genomes of the probiotic strains employed encoded tdc, the TDC protein sequence from Enterococcus faecalis v583 was used as a query along withE. faecalis v583 as a positive control using the BLAST program of PATRIC suite . E. faecalis V583 TDC protein sequence was downloaded in FASTA format. PATRIC suite was used for the Annotation of the six bacterial strains using the RAST tool kit encoded within the software. Annotated genomes were grouped together and BLASTed against the TDC protein sequences.
Should You Take A Probiotic For Parkinsons
Though research on probiotics for treating Parkinsons is a relatively new topic, taking a probiotic may be beneficial in some cases.
If you are experiencing constipation related to PD, you may benefit from taking a probiotic supplement. Though, which formulations are best is yet to be determined.
Beyond this, there isnt enough evidence to provide specific recommendations. Scientists are just beginning to understand the role of the gut microbiome and probiotics and their role in PD. So, its too early to recommend probiotics as a treatment .
If youre interested in probiotics to help alleviate some of your PD symptoms, you should speak to a qualified healthcare professional.
Summary
Since research is still in its early stages, its too soon to recommend probiotics to help manage or treat PD symptoms.

What Does Other Research Show About The Vagus Nerve Connection To Parkinsons
Other research has shown an important relationship between the activity of the peripheral vagus nerve and the function of the dopamine system in the brain in rats. Postmortem studies on humans demonstrated that the brain area known as the dorsal motor nucleus of the vagus, which is connected to GI symptoms, was affected in the early stages of PD.The alpha-synucleins are also present in a number of other neurological brain pathologies, such as multiple system atrophy, dementia with Lewy bodies, many cases of Alzheimers, a subtype of essential tremor and others. Perhaps there is a link with the GI tract in these other pathologies.

What Is The Microbiome
The human gut harbors trillions of micro-organisms referred to collectively as the microbiome. Current understanding is that the microbiome provides a number of benefits to the human including help with digestion of food, help with warding off harmful microorganisms, aid in the absorption of particular nutrients, and creation of needed vitamins. These functions can influence the nervous system of the gut, called the enteric nervous system . In addition, the gut microbiome releases byproducts and metabolites that have effects on nerves. The microbiome varies from person to person and is influenced by many factors including diet, environment, and genetics. Although no two microbiomes are identical, people with certain diseases may share similarities in their microbiomes.

Probiotics For Parkinson Patients
In light of this, the chief physician Dr Martin Heine, head of the neurology department at the Feldbach/Fürstenfeld state hospital, conducted a pilot study: Over a time period of 8 weeks, doctors studied the effects of special multi-species probiotics on the digestion and motor function of Parkinson patients. Results show that the stool frequency clearly increased through the use of the probiotics, and especially the form and consistency improved vastly: Before starting the probiotic therapy, the stool consistency was a clear indication of constipation . After the 8-week probiotics intake, patients had optimal faeces. Notably positive was the fact that the Parkinson patients didnt suffer from unwanted reactions such as diarrhoea or bloating, as opposed to standard laxatives.

Causes & Symptoms Of Parkinson’s Disease: An Overview
On the neurological level, PD is thought to be the result of a buildup of toxic proteins that kill off neurons in a part of the brain called the substantia nigra. Certain neurons in this part of the brain are responsible for making dopamine. Dopamine is a neurotransmitter and hormone that is vital for many important functions, including movement, memory, and motivation.
Scientists believe that lower dopamine levels cause the motor symptoms of PD, as well as many psychological disorders. Unfortunately, clinical studies have not been able to pinpoint the reason why the toxic proteins begin to build up in the substantia nigra in the first place. It is theorized that this occurs due to a combination of genetic and environmental factors.
There are two types of PD. In one type, the damage is first observed in the brain as a loss of neurons. In the other type, symptoms originally present as inflammation in the intestinal lining.
The gut-brain axis is also involved in the pathogenesis and symptoms of Parkinsons disease. The loss of dopamine-producing neurons in the brain results in the reduction of dopamine which, in turn, leads to an onset of neurological symptoms. In some cases, inflammation of the intestinal lining plays a role in the progression of PD, and gastrointestinal symptoms may be present for years prior to neurological symptoms.
- A tremor in the hands, limbs, jaw, or head
- Difficulty with balance and coordination
- Muscle stiffness
- A slow, shuffling gait

Could A Probiotic Prevent Or Reverse Parkinson’s
Because the misfolded protein that appears to kill dopamine-producing neurons in the brain in Parkinsons disease may originate in the gut in some people, potential prevention strategies could target both gut and brain. Probiotics might be able to help in both ways, but further human studies are required.
In the gut, Lactobacillus acidophilus and L. plantarum have been shown to prevent and repair inflammation in the intestines, which is the leading cause of altered communication in the gut-brain axis. Probiotics like these are already commonly used in the treatment of constipation, and constipation as a symptom of PD is no exception.
Beyond alleviating a distressing non-motor symptom for PD patients, gut health probiotics might also have a potentially preventative role to play. Some people experience GI tract symptoms for up to a decade prior to experiencing the neurological symptoms of PD. If probiotics could alleviate the chronic GI symptoms that precede PD for so many patients, could the onset of neurological symptoms be slowed or prevented? The answer to this question is as yet unknown, but future long-term human studies may shed more light.
The Pros Of Probiotics
One strategy to try and reintroduce good bacteria is to use a treatment called faecal transplantation. This involves collecting bacteria that live in the gut of a healthy donor from a stool sample, and preparing and transplanting them via a tube directly into the gut of the recipient. But while this may work for some conditions where the gut microbiota is abnormal, the process is difficult and still needs regulatory approval and safety checks before it could be made available more widely. So, researchers have been investigating other ways to get good bacteria back into the gut.
A faecal transplant may provide a more direct route for live bacteria to reach the gut but what about oral probiotics? Unfortunately, the bacteria in many commercial probiotics are unlikely to reach the lower gut, where they are needed, as most types of bacteria are wiped out on route by the acidic environment in the stomach. However, with the right combination of good bacteria and delivery mechanism, this may not be inevitable.

Clinical Evidence For Probiotic Supplementation In Parkinsons Disease
Several studies have demonstrated the benefits of probiotic supplementation in PD patients, particularly as a treatment for constipation. Constipation is a very common symptom in PD, with a reported prevalence of up to 70%. Constipation causes significant distress to many patients and can sometimes lead to serious complications such as intestinal pseudo-obstruction, volvulus, and acute urinary retention. The problem is also often insufficiently responsive to currently available laxative treatments.
In an open-label study of 40 PD patients, supplementation of fermented milk containing Lactobacillus casei Shirota , together with diet therapy, for 6weeks was associated with a significant increase in the number of days of bowel opening with normal stool consistency and improvement in constipation-associated bloatedness, sense of incomplete emptying, and abdominal pain.
Two subsequent double-blind placebo-controlled randomized clinical trials have provided class I evidence for the use of probiotics as a treatment for constipation in PD., In the first RCT, 120 PD patients were randomized to receive either fermented milk containing multiple probiotic strains , combined with prebiotic fiber , or a placebo for 4weeks. There was a significant increase in the number of complete bowel movements per week, as measured by stool diary, as well as improvements in bowel frequency, stool consistency, and frequency of laxative usage, in the treatment group.
What Is Parkinsons Disease
Parkinsons Disease is a progressive neurological disorder which affects around 120,000 people in the UK. Progressive means that it typically worsens over time and neurological means that it affects the nervous system . The main symptoms of Parkinsons are slowness of movement , rigidity, tremor and postural instability . While Parkinsons is typically described as a movement disorder, a person with Parkinsons may experience a range of other symptoms including constipation, low mood, fatigue, sleep and memory problems. Symptoms of Parkinsons can be grouped into two major categories motor symptoms and non-motor symptoms .
Parkinsons typically strikes in middle age, with around 80% of cases presenting between ages of 40 and 70, and progression of symptoms is generally slow and continuous. Younger people who develop Parkinsons are more likely to have a relative with the illness suggesting a stronger genetic component. Symptoms usually begin gradually and motor symptoms are often preceded by non-motor symptoms such as fatigue, loss of smell, depression, constipation and sweating abnormalities.
If you are concerned that you or a friend or family member has symptoms of Parkinsons, you or they should see a GP immediately.

Can An Altered Microbiome Contribute To A Diagnosis Of Pd
Research studies in animals have shown that an altered microbiome might contribute to PD pathology. For example, one study showed that in a mouse model of PD that overexpressed alpha-synuclein, there was more alpha-synuclein accumulation in the brain of the mice with an intact microbiome as compared to the same mice who were raised in a germ-free environment with no bacteria in their gut. This supports the theory that abnormal alpha-synuclein accumulation in the brain is enhanced by a particular microbiome in the gut.
Other studies showed that transplantation of fecal material from PD mice to normal mice, thereby introducing a PD microbiome into mice without PD pathology their brain, led to impairment of motor function and a decline in brain dopamine. These studies also support the theory that a particular microbiome might be integral in causing PD pathology in the brain.

Naturaltreatment For Parkinsons #9 Exercise And Other Alternative Therapies:
Regular exercise has been shown to help Parkinsonssufferers by reducing muscle stiffness, increasing mobility, and enhancing postureand balance. Exercise also increases oxygen levels and neurotransmitters, alongwith releasing potent mood elevating chemicals called endorphins.
The type of exercise performed for PD is crucial. Aqua orwater aerobics can be particularly useful as traditional exercise is usuallyquite difficult for many Parkinsons sufferers. Muscle decline, loss of strength,stiffness and loss of balance can make conventional exercises difficult toperform. The great thing about aqua aerobics is it still has the same benefits as other exercise regimens,but the risk of falling is eliminated.
Other types of exercises that can be beneficial for PDsufferers include Tai Chi, Yoga, dancing, walking, aerobic/jazzercise classes,and general stretching.

Scientists Create A Probiotic For Treatment Of Parkinsons Disease
Probiotics are good for the gut, and new research suggests they could also improve symptoms of Parkinsons disease. Scientists have engineered a probiotic bacterium to create L-DOPA which later gets converted into dopamine. Animal studies show the unique treatment is not only safe, but also takes away any side effects of taking L-DOPA orally.
People with Parkinsons disease have low dopamine levels. A common treatment is to replace the dopamine using levodopa L-DOPA tablets that need to be taken orally 3 to 4 times a day. The treatment is effective in reducing Parkinsons symptoms but problems with motor control occur 5 years after taking the medication. This likely occurs because the delivery of L-DOPA to the brain is not constant.
We are harnessing the metabolic capability of beneficial microbes that live in the gut to synthesize a molecule that is the gold standard therapeutic strategy for Parkinsons disease, says Anumantha Kanthasamy, PhD, professor and Johnny Isakson Chair of the Georgia Research Alliance Eminent Scholar at the University of Georgia. This next-generation microbial bioengineering technology is designed so that Parkinsons patients could make their own L-DOPA with microbes in their gut.
When testing the treatment on rodents and dogs, the team found consistent L-DOPA levels in the blood and brain. In a mouse model of Parkinsons disease, the probiotic improved motor, cognitive, and mood symptoms.

How Probiotics Might Help Pd Patients
For many years, Parkinson’s disease was thought to be an affliction of the brain, with the loss of neurons in the substantia nigra as the sole indication of deficiency. Many in the scientific community now strongly believe that PD is closely related to and in many cases caused by imbalances in the microbiome of the gut. The human brain communicates with the intestines and other digestive organs along the gut-brain axis. It is this line of communication that keeps a healthy balance of dopamine flowing throughout the brain and to the motor neurons that control all of our voluntary movements.
Currently, there is no cure for Parkinson’s disease, but there are science-backed options that can potentially help delay progression of the disease and alleviate some of its most uncomfortable aspects. For example, people who adhere to the Mediterranean diet, eating less refined sugar, salt, and saturated fat than the typical Western diet, may delay the onset of Parkinson’s disease by up to 17 years.
