Scientists Homing In On A Cure For Parkinsons Disease

‘Miracle’ Parkinson’s treatment to be trialled in Australia | 7NEWS

The new peptide shows promise as a drug precursor to treat Parkinsons disease, often known for its distinctive hand tremors.

A peptide known to prevent the protein error that gives rise to Parkinsons disease has been optimized by scientists, making it a strong candidate for future development into a cure.

Parkinsons disease is characterized by a specific protein in human cells misfolding, where it becomes aggregated and malfunctions. The protein alpha-synuclein is abundant in all human brains. After misfolding, it accumulates in large masses, known as Lewy bodies. These masses consist of S aggregates that are toxic to dopamine-producing brain cells, causing them to die. It is this drop in dopamine signaling that triggers the symptoms of Parkinsons, as the signals transmitting from the brain to the body become noisy, leading to the distinctive tremors seen in sufferers.

Previous efforts to target and detoxifyS-induced neurodegeneration have seen scientists analyze a vast library of peptides to find the best candidate for preventing S misfolding. Of the 209,952 peptides screened in earlier work by scientists at Bath, peptide 4554W showed the most promise, inhibiting S from aggregating into toxic disease forms in lab experiments, both in solutions and on live cells.

    The American Academy of Neurology has issued a guideline providing recommendations for treating movement symptoms, called motor symptoms, in people with early Parkinsons disease. The guideline is published in the November 15, 2021, online issue of Neurology, the medical journal of the AAN, and is endorsed by the Parkinsons Foundation. This guideline updates recommendations on dopaminergic medications that were published in the 2002 AAN guideline on the initiation of treatment for Parkinsons disease.

    Parkinsons disease can progressively affect all movement including manual dexterity, speech, walking and balance due to a gradual reduction of a chemical in the brain called dopamine, a substance that helps control movement. Motor symptoms in the early stages of Parkinsons disease include tremor, rigidity and bradykinesia, which is slowness of movement. To relieve these early symptoms, treatment options include dopaminergic medications, drugs that increase dopamine levels or mimic dopamine effects.

    Aiming For Timely Diagnosis

    As with many chronic conditions, earlier recognition of Parkinsons disease can help people experience an enhanced quality of life.

    2016 statistics reflect that around 6.1 million people worldwide had Parkinsons, more than double than in 1990. However, this increase doesnt necessarily mean that Parkinsons disease is more common now.

    The rise could be the result of increasing awareness of the disease, causing more people to contact a doctor about potential symptoms. The global population is , meaning more adults are in the at-risk age category for Parkinsons disease.

    A of research findings suggests a timely diagnosis of Parkinsons disease can provide the following benefits, among others:

    • support your right to know about the disease as soon as possible
    • enable you to take an active role in your health and well-being surrounding disease management and treatment options
    • allow you to engage with ongoing research into Parkinsons disease
    • help you understand that the symptoms of Parkinsons arent just part of aging but a specific health condition

    Discovery Points To Possible Driver Of Parkinson’s Disease

    by The Scripps Research Institute

    Parkinson’s disease may be driven in part by cell stress-related biochemical events that disrupt a key cellular cleanup system, leading to the spread of harmful protein aggregates in the brain, according to a new study from scientists at Scripps Research.

    The discovery, published in The Journal of Neuroscience in February 2022, offers a clear and testable hypothesis about the progression of Parkinson’s disease, and may lead to treatments capable of significantly slowing or even stopping it.

    “We think our findings about this apparent disease-driving process are important for developing compounds that can specifically inhibit the process of disease spread in the brain,” says study senior author Stuart Lipton, MD, Ph.D., Step Family Endowed Chair, founding co-director of the Neurodegeneration New Medicines Center, and professor in the Department of Molecular Medicine at Scripps Research.

    In both diseases, affected neurons contain abnormal protein aggregations, known as Lewy bodies, whose predominant ingredient is a protein called alpha-synuclein. Prior studies have shown that alpha-synuclein aggregates can spread from neuron to neuron in Parkinson’s and LBD, apparently transmitting the disease process through the brain. But precisely how alpha-synuclein aggregates build up and spread in this way has been unclear.

    The Key Is The Activation Of Ppn Neurons

    In Parkinsons Disease, nerve cells that produce dopamine progressively die. Since the 1960s, doctors have relied on medication to replace the missing dopamine, but it is notoriously difficult to fully control symptoms as the disease progresses.

    In many people the movement symptoms do not respond well to medical treatment in the later stages of this disease, so there has been done a lot of research into alternative treatments, including a search for optimal targets for deep brain stimulation, explains Postdoc Debora Masini, first author of the new study, which included several different strategies to substantiate their findings.

    When we stimulated these specific neurons in the caudal area of the PPN, the animals were able to walk normally, across longer distances and with normal walking speed, as opposed to before the stimulation, where they would display symptoms of Parkinsons Disease, says Debora Masini.

    We systematically compared stimulation of different locations and cell types in a series of complementary experiments. And they all pointed towards the same conclusion. It strongly indicates these excitatory neurons in the caudal PPN are an ideal target for recovery of movement loss, she says.

    The researchers hope that the new study could aid clinicians when they pick the exact location for DBS in the brainstem.

    If I Am Unhappy With My Treatment Can I Seek A Second Opinion

    Each country has its own agreed process to follow if you are unhappy with your treatment. Who you complain to will depend on which part of your treatment you are unhappy with. If it is not your own doctor you are unhappy with, then it is usually a good idea to talk to them first.

    If you are unhappy with your own doctor you may find it helpful to contact a patient advice service or patient liaison organisation. The Parkinsons association in your country should be able to provide contacts and advice this website contains the contact details for Our members and Other Parkinsons organisations.

    Promising New Medication For Parkinsons

    NLX-112 has shown promising results in the lab for reducing dyskinesia caused by the medication Levodopa, which is a common and distressing side effect of current Parkinsons medications. Dyskinesia causes involuntary movements that can affect various parts of the body, making simple, everyday tasks like tying your shoelaces difficult.

    The clinical trial aims to assess whether NLX-112 is safe and well-tolerated by people suffering from Parkinsons who also experience dyskinesia. It will also analyse how the drug can reduce dyskinesia and other non-motor symptoms such as depression and disturbed sleep.

    Adrian Newman-Tancredi, PhD, DSc, Chief Executive Officer of Neurolixis, commented: We are delighted that this important trial is now underway, and the first participant has been recruited. The pandemic has made getting to this point more challenging and time-consuming than wed hoped, but were now keen to make up for lost time. If recruitment to the study progresses smoothly, we are hopeful that we will have results to share by late 2022.

    Foods High In Saturated Fat

    Australian doctors crucial in Parkinsons disease cure efforts | 9 News Australia

    The role that foods high in saturated fats play in Parkinsons progression is still under investigation and is often conflicting. We might eventually discover that there are certain types of saturated fats that actually help people with Parkinsons.

    Some limited research does show that ketogenic, low-protein diets were beneficial for some with Parkinsons. Other research finds high saturated fat intake worsened risk.

    But in general, foods that have been fried or heavily processed alter your metabolism, increase blood pressure, and impact your cholesterol. None of those things are good for your body, especially if youre trying to treat Parkinsons.

    The Latest In Parkinsons Medications: Taking A Personalized Approach

    From renowned singer Linda Ronstadt to former NBA player Brian Grant, the faces of Parkinsons disease are as diverse as the symptoms. While there can be common themes such as slowed movement or stiffness each persons PD experience is unique, making individually tailored therapy vital. Fortunately, the list of medications and treatments that improve quality of life for people living with PD continues growing.

    This article is based on a Parkinsons Foundation Expert BriefingParkinson’s Disease & Medication – What’s Newpresented by Vanessa K. Hinson, MD, PhD, Movement Disorders Program director, Medical University of South Carolina, a Parkinsons Foundation Center of Excellence.

    Parkinsons disease can vary widely from one person to another. Whether or when someone might experience rapid, involuntary and uncontrollable body movements, called dyskinesias, as a complication of some Parkinsons medications can also fluctuate. Cognitive changes or multitasking can pose challenges for some who live with PD, while others might experience hallucinations. Optimal PD treatment and care should be based on your unique symptoms and help you to live your best life.

    Why The Public Is Afraid To Talk About ‘parkinson’

    When hearing about Parkinson’s disease, many people talk about “Pa” discoloration. In fact, Parkinson’s disease itself is not fatal and generally does not affect life expectancy. However, a series of symptoms of Parkinson’s disease can lead to more serious consequences. For example, when some patients are crossing the road, they suddenly “close” without warning, their feet seem to stick to the ground, and they are motionless, which can easily lead to traffic accidents dysphagia can cause pneumonia and increase the risk of death from suffocation Problems with balance and posture can lead to falls, fractures, and traumatic brain injuries. The above fatal consequences caused by Parkinson’s disease should arouse the vigilance of Parkinson’s disease patients. In addition, once Parkinson’s disease develops to an advanced stage, the patient’s motor function will be devastated, and the patient will suffer from a decline in immunity due to difficulty in walking, inability to take care of themselves, and bedridden, frequent pneumonia, bedsores, and urinary tract infections. Complications can even be life-threatening.

    What Are The Different Stages Of Parkinsons Disease

    The Parkinsons Drug Trial: a Miracle Cure? episode 2 ...

    Each person with Parkinsons disease experiences symptoms in in their own unique way. Not everyone experiences all symptoms of Parkinsons disease. You may not experience symptoms in the same order as others. Some people may have mild symptoms others may have intense symptoms. How quickly symptoms worsen also varies from individual to individual and is difficult to impossible to predict at the outset.

    In general, the disease progresses from early stage to mid-stage to mid-late-stage to advanced stage. This is what typically occurs during each of these stages:

    Early stage

    Early symptoms of Parkinsons disease are usually mild and typically occur slowly and do not interfere with daily activities. Sometimes early symptoms are not easy to detect or you may think early symptoms are simply normal signs of aging. You may have fatigue or a general sense of uneasiness. You may feel a slight tremor or have difficulty standing.

    Often, a family member or friend notices some of the subtle signs before you do. They may notice things like body stiffness or lack of normal movement slow or small handwriting, lack of expression in your face, or difficulty getting out of a chair.

    Mid stage

    Mid-late stage

    Standing and walking are becoming more difficult and may require assistance with a walker. You may need full time help to continue to live at home.

    Advanced stage

    Exercise May Improve Outcomes

    Researchers continue to find evidence that exercise is helpful in Parkinsons disease. Exercise induces the production of neurotrophic factors, reduces oxidative stress, decreases neuroinflammation, and improves cerebral blood flow. For these reasons, exercise might provide neuroprotection.

    Improvements in activity-monitoring technology have made tracking activity easier and data collection quicker. Also, sample sizes required for exercise studies have decreased.

    The National Parkinsons Foundation is sponsoring the Parkinsons Outcome Project, a longitudinal registry that collects outcomes data on 9,000 international participants annually. Early in the course of this , it became clear that patients who exercised did better, said Dr. Davis. Whether exercise caused improved outcomes was uncertain, however. Physicians have begun encouraging the sedentary study participants to exercise, and the rate of decline has slowed for the patients who began exercising.

    We do not have enough information now to give people exercise prescriptions, said Dr. Davis. But activity in general is so much better than inactivity that we just tell patients to find something that they like and do it.

    Parkinson’s Protein Blueprint Could Help Fast

    Researchers have solved a decade-long mystery about a critical protein linked to Parkinsons disease that could help to fast-track treatments for the incurable disease.

    The research, published in Nature, has for the first time produced a live action view of the protein, called PINK1, in exquisite molecular detail.

    The discovery explains how the protein is activated in the cell, where it is responsible for initiating the removal and replacement of damaged mitochondria. When the protein is not working correctly, it can starve brain cells of energy, causing them to malfunction and in the long term die, as happens to dopamine-producing cells in Parkinsons disease.

    The discovery is the culmination of a project spanning eight years and provides the first detailed blueprint for the discovery and development of therapeutic agents that could help to slow or even stop the progression of Parkinsons disease.

    Led by PhD student Mr Zhong Yan Gan and Professor David Komander, the multidisciplinary team at WEHI used innovative cryo-electron microscopy facilities and research to make the discovery.

    Current Parkinsons Treatments Cant Slow Down Onset Of Disease

    Parkinsons is a long-term degenerative disorder of the central nervous system, which mainly the area of the brain that controls movement leading to a slow onset of symptoms including tremors, rigidity and slow movement.

    More than 10 million people worldwide are estimated to be living with Parkinsons disease, according to the US-based Parkinsons Foundation, with the Parkinsons News Today website saying it affects 1,900 per 100,000 among those aged over 80,

    Typically, by the time people are diagnosed with the condition, they have already lost between 70% and 80% of their dopamine-producing cells, which are involved in co-ordinating movement.

    While current treatments mask the symptoms, there is nothing that can slow down its progression or prevent more brain cells from being lost.

    As dopamine levels continue to fall, symptoms get worse and new symptoms can appear.

    What Are The Latest Approved Treatments For Parkinsons Disease

    Several medicines have been approved for the treatment of Parkinsons disease. Here are some of the available medicines for Parkinsons disease:

    Nuplazid 3,4
