My father collapsed at home, his face slack, his words gone.

In Shakespeare’s Henry VI, they called it a sudden outrage:
“What sudden outrage hath struck thee down?”

But for us, it was something simpler.

A stroke.

And life was never the same.

My uncle survived his stroke, but lost half his body to paralysis.

But now, with all my training, stroke feels like an enemy we still haven’t defeated.

Until maybe now.

Every Minute Counts — And Millions of Brain Cells Die Waiting

Doctors have a saying:

“Time is brain.”

For every minute your brain goes without blood flow, you lose almost 2 million neurons — and about a week of independent life.

Most strokes are ischemic — caused by a clot that blocks blood flow to the brain.

The clot may form in place (thrombotic stroke) or travel from elsewhere (embolic stroke).

Today, we treat them with two main tools:

• With clot-busting drugs like tPA.
• Or by physically removing the clot with a device snaked into the brain.

But here’s the harsh truth:

Even today’s best devices fail on the first try about half the time.

And the longer it takes, the worse the outcome.

A Spinning Breakthrough: The Milli-Spinner

Now, something new.

At Stanford, engineers built a tiny device called the milli-spinner.

It’s smaller than a pencil tip but spins like a turbine.

Placed next to a clot, it crushes and shrinks the blockage by up to 95% — in seconds.

No more multiple passes — and far fewer complications.

No more dangerous fragments breaking free.

Just restored blood flow — fast.

In early animal tests, it worked almost every time.

Dr. Jeremy Heit called it “a sea change.”

Others called it something simpler: magic.

If it works in people as well as in animals, it could save tens of thousands of lives a year — and prevent countless families from facing what mine did.

Other Stroke Breakthroughs You Should Know

The milli-spinner isn’t the only new advance reshaping stroke care:

AI That Spots Strokes in Seconds

New artificial intelligence tools can scan CT images instantly — alerting hospitals before a doctor even sees the scan.

Ambulances With Brain Scanners

Mobile stroke units bring the ER to your driveway — starting treatment minutes earlier than ever before.

Safer, Longer-Lasting Clot-Busters

Researchers are developing clot-busting drugs that last longer and work for more patients — even those who arrive late.

Microrobots That Swim Through Blood

In the future, magnetic millirobots may be able to swim through your blood vessels, crushing clots before they cause damage.

It sounds like science fiction.

But it’s happening.

If This Had Existed, My Father Might Be Alive

When my father had his stroke, we didn’t have these options.

We utilized the best tools available at the time.

But even the best tools weren’t enough.

That’s why this work matters.

That’s why I tell my patients — and you — about it.

What You Can Do Right Now

Stroke breakthroughs are coming.

But your best defense is prevention — and fast action when a stroke strikes.

Know the Warning Signs: FAST

• Face: Drooping on one side?
• Arms: Weak or numb?
• Speech: Slurred or strange?
• Time: Call 911 immediately.

Lower Your Risk

• Control high blood pressure.
• Stop smoking.
• Exercise daily.
• Manage cholesterol and diabetes.
• Treat atrial fibrillation, an irregular heartbeat that causes many strokes.

Prepare Your Family

• Know where your nearest stroke center is.
• Make sure your family knows what to do if you collapse.
• Keep a list of your medications and medical history handy.

The Future of Stroke Care: Almost Here — But Not Yet

In medicine, there are no miracles.

But sometimes, there are tiny machines with spinning fins — small enough to dance inside your blood vessels — saving your brain before it’s too late.

I wish my father had lived to see this.

But maybe another family won’t have to say goodbye so soon.

The addictive properties of nicotine are well-documented. The inhaled nicotine while vaping has the potential to disrupt the normal functioning of multiple brain regions. Because of this, nicotine may become more appealing as the brain craves this substance in increasing quantities.

Nicotine impacts the following brain functions:

1. Reward processes are an integral part of the brain’s mechanisms for motivation. These systems direct actions to maximize good results and minimize bad ones. But is that always the way things go?
2. Executive function is essential for controlling one’s ideas, deeds, and emotions, and vaping may be involved here, too.

When nicotine enters the brain, it mimics the effects of other forms of reward, such as food, sex, and social connection. The brain’s reward and executive function systems can be “hijacked” by nicotine, making them more sensitive to cues involving nicotine.

The brain associates vape design logos and the shapes of a vape device with nicotine through repeated exposures. In this, we are no better off than Pavlov’s famous dogs and their salvation when they saw food and then, simply, the empty bowl that represented food.

Simply put, it is a learning process, and the brain responds accordingly by prompting a desire for the object (nicotine) and the means to it (vaping).

Then, too, addictive substances lead to increased tolerance and cravings. Many students quickly use up their electronic cigarettes despite the promised three-month duration for a vaping device. This alone points to the excessive use of the devices and addiction.

To conduct this study, researchers in Ecuador administered cognitive tests to over 400 college students aged 18 to 30. Of these, 111 smoked cigarettes and vaped, 64 smoked exclusively, and 31 smoked alone.

Cognitive tests indicated that smokers and vapers consistently performed worse than non-smokers and non-vapers.

Is it necessary to wait for this research to be published in a peer-reviewed journal before we realize the dangers posed by vaping? The harm is happening right now, and waiting is questionable.

What Does Smoking Do to the Brain?

Most smokers think this activity may affect only the lungs, but scientific studies have shown that it also affects the brain and the digestive system.

Recent research found that smoking reduces brain size. Consequently, smoking effectively speeds up the aging process of the brain’s normal loss of brain volume with age. Although scientists have recognized the correlation between smoking and reduced brain capacity for some time, they have remained puzzled about the exact cause. And there is a person’s genetic makeup to think about, too.

This loss of brain tissue, which can be natural or artificial, is raising the issue regarding smoking or vaping, which may be a precursor to Alzheimer’s disease.

I’ve previously written about the research on vaping and what it discloses regarding the various dangerous elements that can be in a vaping cartridge. The outlook wasn’t pleasant then, and this additional research input appears to prove even more concerning now.

We know it’s not just smoking cigarettes that can cause the brain to reduce in size because vaping may do it, too. Pulling in the smoke and pushing it out of your mouth is not without consequences. Anyone who does this needs to be informed of the dangers.

Smoking or vaping can provide short-term respite for certain people with mental health issues, who may use it as a “self-medication” method. Nicotine withdrawal, on the other hand, could make depressive and anxious feelings much worse.

Cancer is one illness that frightens many people, and for good reason. No one wants to do something to encourage cancerous growth, but here is one that does. Tobacco use is associated with an increased likelihood of colon cancer. The second most common cancer killer is colon cancer. How attractive is a colostomy bag for a college student? Would they trade it if they could and not have to have one because they didn’t smoke?

When we consider what might be highly important to college students, e.g., getting into graduate school or passing tests for job opportunities, vaping rises in significance to them. Diminished ability on any cognitive testing can be an important reason to quit vaping if it stymies your ability to get into a highly desirable program or a job with a fantastic future.

Legal Restrictions of E-cigarettes

“As of March 31, 2024, 50 states (Alabama, Alaska, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Idaho, Indiana, Iowa, Kansas, Louisiana, Maine, Maryland, Massachusetts, Minnesota, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Dakota, Ohio, Oregon, Pennsylvania, Rhode Island, Texas, Utah, Vermont, and Washington), the District of Columbia, the Northern Mariana Islands, Palau and the U.S. Virgin Islands have passed legislation that requires a retail license to sell e-cigarettes over-the-counter.” There are also restrictions as well as regulations on the age of any person to purchase these products in these states or territories.

American Samoa and the Marshall Islands do not have any legislation requiring a minimum age.

The situation concerning vaping and the distribution of associated products has now reached the level of federal involvement. To fight the illicit sale and distribution of electronic cigarettes, the Justice Department and the U.S. Food and Drug Administration (FDA) established a federal multi-agency task force today.

In addition to the FDA and the Justice Department, the task force will assemble various law enforcement agencies, such as the ATF, USMS, USPIS, and FTC, to work together in a coordinated and streamlined manner to combat the illicit distribution and sale of electronic nicotine delivery systems (ENDS) like e-cigarettes and vapes, which are causing a surge in nicotine addiction among young Americans.

We can no longer dismiss these products as harmless, and we must see them as possessing a criminal incentive regarding their distribution and use, harming those who purchase them. Those profiting from vaping products will fight against any restrictions using legal means.

Critics may claim discrimination against individual rights, despite the proven dangers of products like alcohol cigarettes. Research tells us that the juvenile mind is not fully mature until about the age of 25 and these products are aimed at a market that is well below that cutoff point. Even at 25, some individuals will not have reached majority in their brain development. Who should protect them from this type of advertising, and do we have an obligation to do it?

Restrictions on over-the-counter products are not new, and when we consider cocaine, this is a good example of where protecting the consumer was legally necessary. In the 20s and 30s, cigarettes containing cocaine were sold in stores, and cocaine-infused beverages and elixirs were freely available for purchase.

The original name for a popular soft drink, Coke-Cola, was derived from the fact that it contained this energizing ingredient. One of Sigmund Freud’s associates, a young physician, became addicted to cocaine, and even Freud himself, at one time, extolled the value of cocaine. He used it on a regular basis and wrote extensively about cocaine in one of his books.

Freud was, in fact, highly addicted to nicotine and may be considered to have had an addictive personality. A chronic smoker, he would light up twenty cigars a day. Was he orally fixated?

He endured a long and arduous 16-year battle after being diagnosed with squamous cell carcinoma of the palate in 1923. At that time, he flat-out refused to give up smoking despite the fact that the fourteen surgeries he had were considered disfiguring and Freud was a vain man.

Ironically, the reason Freud first used cocaine for patients was to free them from morphine addiction. Things did not go well in that regard, and you see where he ended up being addicted to cocaine and small, black cigars.

For the soft drink, the ingredient was removed from the beverage because research indicated cocaine should not be freely available to consumers without medical supervision.

We have the research results, and they are troubling, but we must increase educational efforts regarding vaping to protect the health of the young and, perhaps, the not-so-young.

The post Vaping Kills Brain Cells? Do We Demand Action? appeared first on Medika Life.

According to the World Health Organization, neurological disorders have surpassed all others as the top cause of death and disability on a global scale. Since 1990, the total number of DALYs (disability-adjusted life years) brought on by neurological diseases has increased by 18%. These DALYs include sickness, premature death, and disability.

A new study was published in Nature Neuroscience that examined more than 1,800 common household chemicals. The researchers believed there was a lack of research on the links between these chemicals and brain health. Among these chemicals, they found two that could be harmful: quaternary ammonium compounds, or “quats” or QACs, and organophosphate flame retardants.

Products containing quats include laundry detergent, fabric softeners, hair wash, sunscreen, baby wipes, shaving cream, and disinfectants from brands such as Downy, Clorox, and Lysol.

Organophosphate flame retardants inhibit the maturation of oligodendrocytes, brain cells responsible for producing the protective layer surrounding nerve cells; quats, on the other hand, kill these cells. The cells they kill are the ones responsible for the formation of the all-important Schwann cells that wrap around axons to produce nerve conduction and all muscular and cognitive abilities. Of particular note is that this destruction of Schwann cells leads to multiple sclerosis (MS).

When exposed to chemicals while they are still developing, they can have devastating effects on a child’s central nervous system, which is already quite vulnerable to environmental shocks. On a global scale, cognitive impairments like autism, ADHD, dyslexia, and others affect millions of children.

The American Cleaning Institute has indicated that these products are necessary to contain germs, mold, and viruses that are dangerous to health. As noted on their website, where members and their purpose are listed:

“The American Cleaning Institute (ACI) is the Home of the U.S. Cleaning Products Industry® and represents the $60 billion U.S. cleaning product supply chain. ACI members include the manufacturers and formulators of soaps, detergents, and general cleaning products used in household, commercial, industrial and institutional settings; companies that supply ingredients and finished packaging for these products; and chemical distributors.” They are, therefore, a trade group meant to protect the interests of its members.

Paul Tesar, a director at the Case Western Reserve University School of Medicine and a study author, stated that the researchers believe they have discovered a “previously unrecognized risk factor for neurological disease” due to the correlation between autism, neurological disorders, and disrupted oligodendrocyte distribution.

According to its authors, the research is preliminary and needs to be considered an initial scientific journey into the potential risks and benefits of these products. However, anyone wishing to protect themselves and their children from harm needs to consider even this initial research informative, and use these products prudently and should give serious consideration to any children in the area.

Human brain organoids (HBOs) are made in a lab from human stem cells and look and work like parts of the brain. Since it is clearly impossible to study living humans, scientists have been using animal models and cultured neuronal cells to discern how diseases work. However, these methods still have important differences with real brains, such as how they are organized in three dimensions and differences between species, making it hard to study how the higher brain works. These problems can be addressed in a new way with HBO.

In addition to stem cells, researchers have discovered a new source of research material, one that had never been considered in the past; amniotic fluid. During pregnancy, a baby sheds cells into the amniotic fluid surrounding and protecting it.

As a baby grows inside the womb, these cells mix with the amniotic fluid. Now, scientists have shown that they can use those cells to make organoids, which are three-dimensional structures that look and work like human organs. In one case, the organoids were the kidneys, small intestines, and lungs. Organoids might help physicians learn more about how fetal organs are growing, which could lead to earlier detection of birth defects like spina bifida.

It is not the first time organoids have been made from baby cells. Other groups have grown them from baby tissue that was thrown away. But this group is one of the first to make organoids from cells taken from amniotic fluid.

The idea is innovative, and organoids made from fetal fluid have shown it to work. But there is still room for improvement in how you describe the cells that are there.

For many years, scientists have known that fetus cells are in the amniotic fluid. With amniocentesis, a needle is used to take a sample of the fluid. This lets physicians discern conditions like Down syndrome and sickle-cell disease before the baby is born. At least 95% of these cells the baby is shedding are dead.

Organoids made from baby cells have been made before. Other groups have grown them from leftover fetal tissue. On the other hand, one group is the first to make organoids from cells taken from amniotic fluid. It does not affect the baby.

Most people have heard of mini-brains, which are groups of neurons meant to fire in a way similar to how cells fire in a real brain, but not quite. There have been heated arguments about whether these tiny blobs could ever be aware, feel pain, or think, and whether they should even be called “mini-brains” because they differ from a fully developed human brain.

In another area, thyroid disease, a breakthrough may benefit those who suffer from thyroid disease. One study group working on thyroid cells has successfully used stem cells to make tiny thyroids that can be transplanted into mice, but not humans yet.

Hypothyroidism, or an underactive thyroid, affects about 5% of people and can cause tiredness, aches and pains, weight gain, and sadness. It can also change the way children’s brains grow. And people who have it often have to take a treatment every day to replace their hormones. This team’s efforts resulted in getting mice to make thyroid hormones again, which opened the door for humans. About which therapies will work with cancer, there is hope there, too, derived from studies of organoids.

Patient-derived organoids (PDOs) are new and strong pre-clinical models. However, it is still not clear how well they can predict how patients will do in the clinic. What effects will certain treatments have on a patient’s cancer? Organoids made from patients did help predict how well treatment would work for metastatic gastrointestinal cancers.

Researchers also use organoids to study how the host and bacteria interact. Adding immune system parts to infected organoids would be the next step in this direction. A few methods using triple co-cultures have been created, most of which try to replicate harmful illnesses with viruses or bacteria. In all these important research findings, one consideration must be in the mix; ethics with animal brain organoids and simple organoids in dishes.

Until now, these human brain organoids have only been found in test tubes. The most advanced ones are about the size of a pea and pulse with the electrical activity that makes real brains work. In a way that is similar to brains, they make new neurons. They also build the six layers of the human cortex, which is where thinking, speaking, making decisions, and other complex cognitive processes happen.

Many experts in the field do not think an organoid in a dish can think, but we need to talk about this. While we are discovering new ways to combat illness and developmental issues through the use of these organoids, we are also faced with ethical issues all along the way. Each of these issues must be addressed in a way that will benefit everyone and not inhibit the growth of science in its quest for health.
