Simple tool could detect Parkinson's disease early — it was 96% accurate in experiments

New York Posta day ago

This pen truly is mightier than the sword.
A team of researchers at UCLA has developed a high-tech diagnostic pen that can detect signs of Parkinson's disease with over 96% accuracy, offering a low-cost way to identify the neurodegenerative disorder far earlier than now.
A pilot study in the journal Nature Chemical Engineering unveiled the device, which looks much like a regular pen.

It's able pick up on subtle motor dysfunctions before they're visible to the naked eye, all by analyzing how people write.
So, how does this futuristic fountain pen work?
The tip is made of a flexible silicone material infused with magnetic particles, and it writes using a special ferrofluid ink that contains nanomagnets.
As someone writes, pressure from the hand deforms the tip, causing changes in magnetic fields that produce electrical signals — like a Morse code of motor function.
Those signals are then analyzed to detect the difference between healthy and Parkinson's-affected motor patterns.
In tests with 16 participants — including 3 with Parkinson's — the system nailed the diagnosis with 96.22% accuracy.
Even more impressive? The pen worked whether people wrote on paper or in the air, meaning it doesn't even require a surface.

Today, Parkinson's is largely diagnosed based on observations, which are subjective, or by biomarker-based imaging, which can be expensive.
This diagnostic pen is portable, inexpensive and doesn't rely on a neurologist to interpret results, making it a promising option for remote screenings, home use or even telehealth checkups.
'Our development of the diagnostic pen represents a low-cost, widely disseminable and reliable technology with the potential to improve PD diagnostics across large populations and resource-limited areas,' the researchers wrote.
With further validation in a larger population, the device could be used not just for early diagnosis, but for ongoing symptom tracking and personalized treatment monitoring.

This is just the latest innovation aimed at tackling Parkinson's disease, which affects more than 10 million people worldwide and has no known cure.
A recent study found that psilocybin — the psychedelic compound that gave 'magic mushrooms' their trippy reputation in the 1960s — showed serious promise for improving mood and motor function in people with Parkinson's disease.
Tavapadon — a new drug that mimics dopamine by targeting certain receptors — has also shown promise in clinical trials by reducing motor fluctuations and maintaining symptom control with fewer side effects than traditional therapies.
Produodopa — a continuous infusion therapy first administered in the UK — was approved by the US Food and Drug Administration last fall.
Innovative approaches targeting the psychological aspects of the disease have been successful as well — with tandem cycling proving to be especially popular.

US appeals court confirms patent validity of Acadia's Parkinson's drug

(Reuters) -Acadia Pharmaceuticals said on Monday that the U.S. Court of Appeals has confirmed the validity of its patent for Nuplazid, its drug for hallucinations and delusions associated with Parkinson's disease. The decision supports a December 2023 ruling from the U.S. District Court of Delaware, ensuring the patent remains protected in Acadia's legal battle against India-based drugmaker MSN Laboratories. The appeals court followed a precedent that says an earlier patent claim cannot be invalidated by a later one if they share the same priority date. "We are gratified that the U.S. Federal Appeals Court has affirmed the lower court's ruling in favor of our composition of matter patent for Nuplazid, securing protection into 2030 for this patent, and beyond based on the recent favorable ruling for our formulation patent providing patent protection for Nuplazid 34 mg capsule formulation into 2038," said CEO Catherine Owen Adams. This decision comes after another favorable ruling for Acadia regarding its formulation patent for Nuplazid. The court supported Acadia's claims of infringement and validity in its legal case against Aurobindo Pharma and other companies. The U.S. FDA approved Nuplazid for the treatment of hallucinations and delusions associated with Parkinson's disease psychosis in 2016.

Wildfire smoke can harm your brain, not just your lungs

Wildfires are already burning in parts of Canada, and as they do, many communities are already facing the familiar thick haze as smoke drifts in. Smoke from wildfires has already led Environment Canada to issue air quality warnings for much of Ontario. In Toronto, smoke led to the city briefly having the worst air quality in the world. Anyone who has experienced wildfire smoke knows how it can leave you with a scratchy throat, stinging eyes and impact your lungs. However, smoke can also affect your brain. Tiny airborne pollutants found in smoke have been linked to increased risk of stroke, dementia and flare-ups in neurological diseases like multiple sclerosis (MS). These effects can disproportionately impact older adults, people with disabilities, Indigenous Peoples and those living in low-income communities. This isn't just about climate. It's about equity, and health systems need to catch up. Canada's 2023 wildfire season was the worst on record, and as climate change worsens wildfires, it may be a sign of what's to come. Alongside harmful gases and heavy metals, wildfire smoke contains fine particulate matter, also known as PM2.5. These tiny particles can travel deep into your lungs, slip into your bloodstream and even reach your brain. Some even bypass the lungs entirely, entering the brain directly through the nose. After entering the brain, these toxins can cause inflammation and stress, damage nerve cells and even accelerate cognitive decline. Studies have linked exposure to air pollution to an increased risk of stroke and dementia. Even short-term spikes in smoke exposure, like those during wildfires, lead to a surge in emergency visits for strokes, especially among people over 65. A 2022 experiment had thousands of adults participate in an online attention task under smoky conditions. It found that just a three-hour spike in fine particulate matter, typical of a heavy smoke episode, led to measurably worse attention scores. This fits other evidence that breathing smoke makes people mentally foggy, forgetful or fatigued. In 2024, a study found that chronic exposure to wildfire-related air pollution significantly increased the likelihood of someone being diagnosed with dementia. The risk was most pronounced in low-income communities, where people often have less access to clean air, health care and protective measures. For people already living with neurological conditions like MS or Parkinson's disease, the stakes are even higher. Exposure to fine particulate pollution has been linked with increased hospital admissions for MS relapses, particularly in young patients. Other research points to worsening symptoms of epilepsy and cognitive decline under extreme heat and polluted air conditions. Despite these mounting risks, neurological health considerations have been largely absent from wildfire preparedness initiatives and public health responses. That needs to change. If you want to stay informed about local smoke exposure, tools like AQmap can help you track PM2.5 levels in real time across Canada. Some face far greater risk from wildfire smoke than others, including older adults, those with pre-existing health conditions, people with lower socio-economic status, Indigenous populations, people residing in remote areas and children. This is a health equity issue as much as a medical one. Each of these groups faces unique and compounding challenges during smoke events. For example, older adults are more vulnerable to the cardiovascular and neurological effects of smoke. They also face greater barriers to accessing filtered environments. People with disabilities or chronic illnesses, including those with neurological conditions, often can't relocate during smoke events and may rely on power-dependent medical devices that can fail during climate emergencies. Low-income families are more likely to live in housing without proper air filtration or cooling. These same communities often face higher baseline rates of neurological disease. Indigenous communities, more than 80 per cent of which are located near fire-prone areas, face recurring displacement, interruptions to care and disproportionate exposure to smoke each summer. Children and adolescents are particularly susceptible to the harmful neurological effects of wildfires. Because their brains are still developing and they breathe more air per body weight than adults, children are especially vulnerable to harmful pollutants. Studies have linked early-life exposure to fine particulate matter with an increased risk of neuro-developmental disorders, lower cognitive function and structural brain changes. These populations aren't just more exposed, they also have fewer resources to respond. Recognizing these inequities, we are developing a climate-health equity framework for Canada, with a specific focus on neurological health. Our interdisciplinary team is asking: how can we build health systems that protect vulnerable brains during climate emergencies? Health-care workers in Alberta Health Services have designed the Climate-Resilient Acute Care Clinical Operations Framework. This framework supports hospitals in becoming both greener and more resilient, ensuring care can continue during wildfires, floods and extreme heat events. Importantly, it also centres the needs of equity-deserving populations, integrating climate adaptation into emergency care, supply chains, staffing and patient communication. What needs to change? Public awareness must expand beyond respiratory health. Neurological effects of smoke should be included in public health messaging, especially for high-risk groups. Health systems must be climate-ready, with clean air shelters, evacuation protocols and services tailored to meet the needs of neurological patients. Communities need support, from funding for air filtration to co-ordinated outreach during smoke events. Indigenous-led fire stewardship and community health initiatives should be part of national planning. Supporting Indigenous-led fire stewardship not only strengthens wildfire response but also respects Indigenous sovereignty and traditional ecological knowledge. Clinicians must be empowered to address climate-related health risks. Training in environmental health, including its impact on the brain, is increasingly essential. Wildfire season is back, and with it, an urgent need to protect more than just our lungs. The science is clear: breathing smoky air affects our minds, especially for those already facing health and social vulnerabilities. Climate change is a brain health issue. Building a healthier, more equitable future requires us to treat it that way, starting now.

Gut bacteria changes may be warning sign for worsening Parkinson's

Changes in specific bacteria in the mouth and gut of patients with Parkinson's disease could potentially be an early warning sign that symptoms of the condition are getting worse, a study suggests. With the help of artificial intelligence (AI), scientists have linked these shifts to cognitive decline – problems with memory and learning – in people with the disease. They suggest the toxins could one day be used as 'markers' for medics to pinpoint the Parkinson's patients at a higher risk of dementia, as well as being used to help develop targeted treatments for the disease. Parkinson's disease is a progressive condition that affects the brain, with symptoms including involuntary shaking, known as tremors, as well as psychological problems such as depression, loss of balance, trouble sleeping and memory issues. According to the Alzheimer's Society, around a third of people with Parkinson's eventually develop dementia. 'The human gut and oral bacterial communities are increasingly linked to neurodegenerative diseases. Disruptions in the gut-brain axis could trigger inflammation and immune responses that contribute to neuronal damage," Dr Saeed Shoaie, group leader of the quantitative systems biology (QTS) lab at King's College London, said. "A common gum disease bacterium like porphyromonas gingivalis has been discovered as a potential driver of Alzheimer's." For the study, led by experts at King's College London and published in the journal Gut Microbes, scientists analysed 228 spit and stool samples. The samples came from 41 patients with Parkinson's and mild cognitive impairment, which causes problems with thinking and memory, 47 patients with Parkinson's and dementia and 26 healthy patients. The team found that the gut of people with mild cognitive impairment contained more harmful bacteria, many of which are likely to have come from the mouth. This bacteria releases toxins that can damage gut tissue, promote inflammation and potentially affect the brain, according to researchers. For a more in-depth analysis, the team used AI to pinpoint the bacterial species and functions not usually picked up by traditional testing, allowing them to link toxins specifically to cognitive decline. Dr Shoaie added: 'The emerging evidence underscores the potential importance of maintaining oral and gut health in mitigating or slowing neurodegenerative processes. 'As people with Parkinson's become increasingly reliant on carers, routine practices such as oral hygiene and nutritional intake may be neglected. 'Our findings suggest that promoting a healthy microbiome through consistent oral care, a balanced diet and potentially targeted probiotic interventions could support improved disease management in Parkinson's.'
