An experimental treatment happens to be the solution to delay Alzheimer's symptoms in some people. These people are the ones who are genetically destined to get the disease in their 40s or 50s. These new findings form ongoing research has now been caught up in Trump administration funding delas. The early results of the study has been published on Wednesday and the participants too are worried that politics could cut their access to a possible lifeline.

One of the participants had said, "It is still a study but it has given me an extension to my life that I never banked on having." The participant is named Jake Henrichs, form New York City, who is 50 years old. He is one of them to be treated in that study for more than a decade now and has remained symptom-free despite inheriting an Alzheimer's-causing gene that had killed his father and brother around the same age.

Slowing Down The Symptoms

Two drugs which can modestly slow down early-stage Alzheimer's are sold in the United States. These drugs clear the brain of one of its hallmarks, a sticky gunk-like part called the amyloid. However, there have not been any hints that removing amyloid far earlier, way many years before the first symptoms appear, may postpone the disease.

How Was The Research Conducted?

The research is led by Washington University in St Louis, which involved families that passed down rare gene mutation as participants. This meant it was almost guaranteed that they will develop symptoms at the same age their affected relatives did.

The new findings is based on a subset of 22 participants who received amyloid-removing drugs the longest, on average eight years. Long-term amyloid removal cut in half their risk of symptom onset. The study is published in the journal Lancet Neurology.

Washington University's Dr Randall Bateman, who directs the Dominantly Inherited Alzheimer's Network of studies involving families with these rare genes says, "What we want to determine over the next five years is how strong is the protection. Will they ever get the symptoms of Alzheimer’s disease if we keep treating them?”

The researchers before though did not know what exactly caused Alzheimer's which affects nearly 7 million Americans, most of them in their later life. However, it is clear that these silent changes occur in the brain at least two decades before the first symptom shows up. The big contributor. At some point amyloid buildup can trigger a protein named tau that then starts to kill neurons, which can lead to cognitive decline.

Researchers are now thus studying the Tau-fighting drugs and are looking into other factors, like inflammation, brain's immune cells and certain virus.

The National Institute of Health (NIH) has expanded its focus as researchers have found more reasons for Alzheimer's. In 2013, the NIH's National Institute on Aging funded 14 trials of possible Alzheimer's drugs over a third targeting amyloid. By last fall, there were 68 drugs and 18% of them target amyloid. However, there are scientists too who think that amyloid is not everything and their is way more in the brain tissue, immune cells, and more which can be studied.

In Northeast Ohio, late summer usually means backyard cookouts, packed ballfields, and sticky, humid nights. This year, though, it has brought something less welcome: a rise in mosquito bites, and a rise in West Nile virus (WNV) cases.

Local health departments reported that two residents, one in Medina County and another in Cuyahoga County, tested positive for West Nile virus in August, according to Ideastream Public Media. Data from the Ohio Department of Health showed six confirmed cases statewide as of August 21.

Nationwide, the numbers tell a bigger story. According to the Centers for Disease Control and Prevention (CDC), there have been at least 771 human cases reported across 39 states as of September 9. Alarmingly, 490 of those cases were neuroinvasive, meaning they affected the brain or spinal cord, and were potentially life-threatening.

West Nile Virus: The Most Common Mosquito-Borne Illness

West Nile virus remains the most common mosquito-borne illness in the continental United States, according to Vector Disease Control International. Most infected people never develop symptoms, but those who do may experience fever, body aches, nausea, vomiting, or a rash.

In about 1 in 150 cases, the virus causes brain inflammation or meningitis, which can be deadly.

Older adults and immunocompromised individuals face the highest risk of severe complications. “Protecting yourself is especially important for people who are more at risk,” CBS News chief medical correspondent Dr. Jon LaPook emphasized, urging the public to use repellent, wear long sleeves, and drain standing water near their homes.

Why This Outbreak Is Concerning

This year’s surge is not random. Mosquitoes thrive in warm, wet conditions. Longer, hotter summers and heavier rainfall, both linked to climate change, mean longer breeding seasons and more stagnant pools where larvae grow.

"It's always worse in the summer because that's when the mosquito population is at its highest," said Dr. Amy Edwards, an infectious disease specialist at University Hospitals in Cleveland, as reported in The Cool Down. She added that Ohioans face a very different risk today than a generation ago: “For people who grew up in Ohio, mosquitoes and ticks didn't used to carry disease here. Across the U.S., the rate of mosquito-borne illness is going up.”

The trend isn’t limited to West Nile. Lyme disease has been spreading to areas previously considered too cold for ticks, and dengue fever has reemerged in Florida, all signs of vector-borne diseases finding new footholds.

Season Isn’t Over Yet

Public health officials stress that the danger is far from gone. “Infections can continue to occur until the first hard frost of the season, which is likely still many weeks away,” said Dr. Robbie Goldstein, Massachusetts’ public health commissioner, in a recent advisory. He urged people to remain vigilant, as mosquito activity remains high through early fall

The CDC updates its case counts biweekly through ArboNET, a national arboviral surveillance system. The agency notes that symptoms can take between two to fourteen days to appear after a mosquito bite, and in people with weaker immune systems, it can take even longer.

Prevention Remains the Best Defense

There is currently no specific treatment for West Nile virus. For most, recovery involves managing symptoms such as fever and fatigue. Severe cases may require hospitalization for intravenous fluids or even respiratory support.

Health experts recommend taking steps to minimize mosquito exposure:

• Use EPA-registered insect repellent containing DEET, picaridin, or oil of lemon eucalyptus.
• Wear long-sleeved shirts and pants, especially during dawn and dusk when mosquitoes are most active.
• Eliminate standing water in flowerpots, gutters, and other outdoor containers.
• Ensure window and door screens are intact to keep mosquitoes out.

West Nile Virus In The US

West Nile virus, first detected in the U.S. in 1999, is now a recurring part of late summer and early fall. Its growing prevalence serves as a warning of how climate change, urbanization, and changing ecosystems can amplify public health threats.

As the season continues, experts urge residents to stay proactive rather than complacent. The mosquito buzzing around your backyard may be more than an annoyance, it could be carrying a virus that has sickened hundreds this year and shows no sign of stopping.

A new study published in eLife has shed light on why dopamine-producing neurons, the brain cells crucial for motor control, die off in Parkinson’s disease. Researchers from the Gladstone Institute for Neurological Disease in the US found that these neurons may essentially be burning themselves out due to overactivity, potentially triggering or accelerating the condition.

Neurons Working Overtime

Parkinson’s disease is marked by the progressive death of dopamine-producing neurons in the substantia nigra, the part of the brain that controls movement. Building on earlier research in animal models, the Gladstone team explored whether the surviving neurons overcompensate for lost cells by becoming hyperactive, ultimately causing damage to themselves.

To test this theory, scientists used genetically modified mice and stimulated their dopamine neurons with drugs for several days. The result: the neurons gradually degenerated and died, particularly in the substantia nigra, mirroring what happens in human Parkinson’s patients.

“An overarching question in the Parkinson’s research field has been why the cells that are most vulnerable to the disease die,” says neuroscientist Ken Nakamura from the Gladstone Institute. “Answering that question could help us understand why the disease occurs and point toward new ways to treat it.”

Calcium Changes and Gene Shifts

The study went a step further by examining changes inside these overworked neurons. Researchers found alterations in calcium levels and shifts in the expression of genes involved in dopamine metabolism and calcium regulation. These findings were mirrored in brain samples from people with early-stage Parkinson’s disease, suggesting that the mechanism seen in mice is relevant to humans.

“In response to chronic activation, we think the neurons may try to avoid excessive dopamine, which can be toxic, by decreasing the amount of dopamine they produce,” explains neuroscientist Katerina Rademacher, lead author of the study. “Over time, the neurons die, eventually leading to insufficient dopamine levels in the brain areas that support movement.”

A Vicious Cycle

The research suggests a troubling cycle: as some neurons die, the remaining ones become even more active to compensate, which may in turn accelerate their demise. This process is similar to lightbulbs burning too brightly and eventually blowing out.

Scientists have long debated why these vulnerable cells die, with previous theories focusing on faulty mitochondria, toxic protein clumps, and genetic mutations. This new study adds another potential cause to the list, overactivity itself.

Hope for Future Therapies

If confirmed in further studies, this discovery could open the door to new therapies. Adjusting the firing patterns of dopamine neurons with medication or deep brain stimulation might help prevent them from overworking and prolong their survival.

“It raises the exciting possibility that adjusting the activity patterns of vulnerable neurons could help protect them and slow disease progression,” Nakamura notes.

The findings represent a step forward in understanding Parkinson’s disease, offering fresh clues for researchers seeking ways to halt or slow its devastating impact.

Every second counts in an emergency, and World First Aid Day serves as a timely reminder of the critical role first aid plays in saving lives. Observed annually on the second Saturday of September, this day aims to raise awareness about first aid, encourage training, and empower individuals to respond effectively during crises. In 2025, the day will be observed on September 13th, uniting communities worldwide in their commitment to safety and preparedness.

World First Aid Day 2025 Theme

This year’s theme is “First Aid and Climate Change,” highlighting the need for emergency preparedness in the face of increasingly frequent climate-related disasters. Rising global temperatures, floods, wildfires, and storms are creating new challenges for communities, making first aid knowledge more crucial than ever. The theme underscores that basic first aid is not just for personal emergencies but is essential in building community resilience in a changing world.

Importance of First Aid

First aid can make the difference between life and death in the crucial minutes before professional medical help arrives. Whether it’s cardiac arrest, choking, severe bleeding, or burns, timely action can significantly improve survival chances and recovery outcomes. Equipping individuals with basic first aid skills fosters a culture of preparedness, at home, in workplaces, and in public spaces.

In addition to preventing complications and reducing injury severity, first aid training empowers people to act confidently in emergencies. From performing CPR to controlling bleeding and handling choking incidents, these life-saving skills can transform bystanders into first responders.

Origin and Historical Relevance

The roots of first aid go back to the 19th century when Henry Dunant, founder of the Red Cross, witnessed the suffering of injured soldiers during the Battle of Solferino. This inspired a humanitarian movement to care for the wounded without discrimination. The term “first aid” was later coined by German surgeon Friedrich von Esmarch in the late 1800s.

World First Aid Day was first observed in 2000 by the International Federation of Red Cross and Red Crescent Societies (IFRC) to promote global first aid education. Today, millions of people participate in awareness events, training workshops, and community demonstrations, spreading the message that first aid is a universal skill everyone should learn.

How to Participate

Individuals can get involved by attending first aid training courses, sharing educational resources on social media, organizing community workshops, or volunteering with local Red Cross and Red Crescent societies. Even downloading a first aid mobile app can be a step toward being prepared.

A Step Toward Safer Communities

World First Aid Day 2025 is more than a date on the calendar, it’s a call to action. By learning first aid, we can build safer, more resilient communities ready to face emergencies, including those amplified by climate change. This September 13th, take the time to learn, teach, and spread awareness. You might just save a life.
