The US Food and Drug Administration has approved TNKase or Tenecteplase, which is a thrombolytic or clot-dissolving agent, for the treatment of acute ischemic stroke in adults.

Ischemic strokes happen when a blood clot blocks a blood vessel in your brain. It can cause permanent brain damage and death. If enough brain cells die, you can also lose the abilities or body functions those cells control. They are also the most common types of stroke, with 80% of all strokes being ischemic strokes.

How is TNKase administered?

It is delivered as a single five-second intravenous bolus, which is faster than the standard of care Activase or alteplase, which is administered as an intravenous bolus followed by a 60-minute infusion. The manufacturer of TNKase, Genetech said a new 25-mg vial configuration will also be available in the coming months.

How Was TNKase approved?

The approval came at the backdrop of a study that compared TNKase to Activase in patients with acute ischemic stroke. These patients also presented with a disabling neurological deficit. Results show that TNKase was comparable to Activase in terms of efficacy and safety.

How Common Are These Strokes?

In the United States it self, it affects more than 795,000 people each year and is the leading cause of long-term disability. It is also the fifth leading cause of death. Since brain damage can happen if this progresses rapidly, one needs an immediate, fast-acting medical care.

TNKase thus provide a faster and simpler administration which can be critical for anyone. The chief medical officer and head of global product development at Genetech, Levi Garraway, MD., PhD., said, "Today's approval is a significant step forward and underscores our commitment to advancing stroke treatment options for patients."

What Are The Symptoms Of Ischemic Strokes?

Some of the most common symptoms include weakness or paralysis on one side of your face and body. You may also feel trouble speaking or have loss of speech, also known as aphasia. You may faced slurred or garbled speaking, also known as dysarthria. Other symptoms include loss of muscle control on one side of your face, or sudden worsening or loss of your senses, including vision, hearing, smell, taste, and touch.

Other symptoms include:

  • Loss of coordination or clumsiness
  • Blurry vision or double vision
  • Dizziness or vertigo
  • Nausea and vomiting
  • Neck stiffness
  • Mood swings or sudden personality changes
  • Confusion or agitation
  • Seizures
  • Memory loss (amnesia)
  • Headaches which are sudden and severe
  • Passing out or fainting
  • Coma

Are There Any Warning Signs?

While these are symptoms one has who is prone to this condition. However, often, many may confuse it with other illnesses. It is best to keep an eye out for warning signs. These could be looking out for yourself or your loved one. Note if there is a sudden loss of balance. Look out for sudden vision loss or changes in one or both eyes. Look for a droop on one or both sides of your face, especially when you smile. Raise both arms and see if one arm sags or drops in a way it usually does not. Note for your speech. Are you as fluent? Are you have trouble speaking? If you see any of such signs, start tracking it and talk to your healthcare provider.

Millie Bobby Brown has built an impressive career, all while quietly managing a few health concerns along the way. From becoming a household name through Netflix’s hugely popular Stranger Things to leading films like Enola Holmes, the Gen Z actor (now a married mother of one) has made a strong mark in Hollywood. What many people may not realise is that her work has, at times, been shaped by a hearing-related condition. Brown has lived with hearing loss for most of her life, a fact that often goes unnoticed.

Millie Bobby Brown Reveals Having Unilateral Deafness

Brown first spoke publicly about her hearing condition in a 2017 interview with Variety, where she shared that she has had hearing loss in one ear since birth. Even early in her career, she was clear that she would not allow it to stand in the way of her passion for performing. “I just started to sing, and if I sound bad I don’t care, because I’m just doing what I love,” she said at the time. “You don’t have to be good at singing. You don’t have to be good at dancing or acting. If you enjoy it and it makes you happy, you should do it.”

While Brown rarely focuses on her hearing loss, she has spoken about how it affects her daily life. In a conversation with Call Her Daddy host Alex Cooper, she explained that certain sounds, like loud chewing, do not bother her because she can mostly hear herself when she eats. She also shared that her husband, Jake Bongiovi, whom she married in 2022, sometimes jokes that she has “selective hearing.” In reality, she says sounds often feel “muffled, like being underwater.” Brown admitted that she does miss important moments, including hearing directors call out “action” or “cut” on set.

What Is Unilateral Deafness?

Unilateral hearing loss happens when hearing is affected in one ear while the other ear functions normally. Even with hearing in one ear, this condition can make it difficult to understand speech clearly and to identify where sounds are coming from.

The level of hearing loss in one ear can range from mild to severe. When there is little to no hearing at all in one ear, it is described as severe or profound hearing loss, also known as single-sided deafness. Unilateral hearing loss may be present at birth, develop gradually, or appear suddenly. Depending on the cause, options such as hearing aids or cochlear implants may help improve hearing, according to the Cleveland Clinic.

Unilateral Deafness: What Are The Symptoms?

Many symptoms of unilateral hearing loss are similar to those seen with hearing loss in both ears. You may:

  • Ask people to repeat what they’ve said
  • Increase the volume on your television, laptop, or phone
  • Struggle to follow conversations, especially in noisy places like restaurants or busy workplaces
  • If hearing is affected in only one ear, tinnitus, or ringing, may occur on that side alone. You may also notice that you tend to rely more on one ear when speaking on the phone or listening to others.
  • Although unilateral hearing loss often develops slowly, it can also happen suddenly. If you experience a sudden loss of hearing in one ear, it’s important to seek medical advice promptly.

What Causes Unilateral Hearing Loss?

Doctors do not yet fully understand all the reasons why hearing loss occurs in just one ear. Causes can differ between adults and children. In children, hearing loss may be linked to genetics or infections. Possible causes include:

  • Noise-related hearing damage
  • Certain inherited conditions, such as neurofibromatosis Type 2, which can lead to acoustic neuromas in one ear
  • Head injuries
  • Traumatic brain injury (TBI)

Unilateral Hearing Loss: Is There Treatment Available?

According to the American Academy of Audiology, treatment depends on the underlying cause and the severity of the hearing loss. Available options may include:

  • Hearing aids: These are typically worn to support sound perception when one ear is affected
  • Contralateral routing of signal (CROS) devices: This setup uses two devices. One acts as a microphone on the non-hearing side and sends sound to a hearing aid worn on the functioning ear
  • Cochlear implants: These may help restore hearing in the affected ear and improve speech understanding and sound awareness
  • Bone-anchored hearing aids: These devices transmit sound from the non-hearing ear to the hearing ear through bone conduction
  • Frequency modulation (FM) systems: FM systems use radio signals to send sound directly from a microphone to a receiver, such as a hearing aid worn on the non-hearing ear

Can Alzheimer’s Disease Be Reversed? Here’s What the New Research Shows

Updated Dec 26, 2025 | 04:00 PM IST

SummaryNew US research suggests Alzheimer’s disease may be reversible in animal studies. Scientists found restoring NAD levels improved brain function and cognition, raising hope for future treatments. Keep reading for details.

In what researchers are calling an important scientific advance, a team in the US has shown through animal experiments that Alzheimer’s disease may be reversible, overturning a belief that has shaped medical thinking for more than 100 years. For generations, the neurodegenerative condition was considered permanent and progressive. The findings, published in Cell Reports Medicine, are based on multiple preclinical mouse models as well as examinations of human Alzheimer’s brain tissue.

The study found that preserving a healthy balance of NAD, a molecule central to cellular energy production, could both prevent and reverse Alzheimer’s-related damage. NAD plays a key role in brain function and is now seen as a major contributor to the disease process. Researchers also observed that NAD levels drop much more sharply in the brains of people with Alzheimer’s, a pattern that was mirrored in mouse models of the condition.

Alzheimer’s Disease Can Be Reversed, New Study Shows

“We were extremely encouraged by what we observed,” said Andrew A. Pieper, the study’s senior author and Director of the Brain Health Medicines Center at the Harrington Discovery Institute, University Hospitals, as per Sciencedirect. “By restoring the brain’s energy balance, we saw both structural and functional recovery in mice with advanced Alzheimer’s.”

Pieper noted that the effect appeared consistently across two very different mouse models, each driven by separate genetic mechanisms linked to Alzheimer’s in humans. “Seeing recovery in models caused by distinct genetic pathways strengthens the case that restoring NAD balance in the brain could have real therapeutic potential for patients,” he said.

For the study, researchers examined mice engineered to carry genetic mutations known to cause Alzheimer’s disease in people. One group of mice carried multiple human mutations affecting amyloid processing, while the second group carried a human mutation in the tau protein.

After confirming that brain NAD levels dropped sharply in both human Alzheimer’s tissue and mouse models, the team tested whether stopping this decline before symptoms appeared could prevent disease, and whether restoring NAD levels after the disease had progressed could reverse it. To do this, they used a well-studied drug called P7C3-A20 to restore NAD balance in the brain.

The results were striking. Not only did maintaining NAD levels prevent Alzheimer’s from developing in mice, but starting treatment later, after the disease was already advanced, allowed the brain to repair the main pathological damage caused by the genetic mutations. In both mouse models, cognitive abilities were fully restored.

What Is NAD In Alzheimer’s?

In Alzheimer’s disease, NAD, short for nicotinamide adenine dinucleotide, is an essential coenzyme whose levels naturally decline with age. This decline disrupts energy production, mitochondrial health, DNA repair, and the ability of neurons to withstand stress. Research suggests that increasing NAD levels, often through precursors such as nicotinamide riboside, may reverse Alzheimer’s-related damage, improve memory, and correct abnormal RNA processing in animal models. Because of this, NAD has become a major area of focus for developing new Alzheimer’s therapies, according to the National Institutes of Health.

Why NAD Is Important In Alzheimer’s

  • Energy and Mitochondria: NAD is necessary for producing ATP, the cell’s main energy source, and for keeping mitochondria functioning properly, both of which are critical for healthy brain cells.
  • Cellular Stress: NAD supports neurons in responding to and surviving stress. When NAD levels fall in Alzheimer’s, these protective mechanisms weaken.
  • DNA Repair: NAD is involved in repairing DNA damage, which increases as amyloid-beta accumulates in the brain. Low NAD levels interfere with this repair process.
  • RNA Splicing: Emerging research shows that NAD may help correct faulty RNA splicing events linked to Alzheimer’s. This process may involve a protein called EVA1C and could contribute to improved memory and better clearance of harmful proteins.

Next Steps Toward Human Trials

The findings also pave the way for further research and eventual testing in people. The technology behind the treatment is currently being developed for commercial use by Glengary Brain Health, a Cleveland-based company co-founded by Dr. Pieper.

“This recovery-based treatment approach now needs to be tested in carefully designed clinical trials to see if the benefits seen in animals can be replicated in humans,” Pieper said.

He added that future laboratory work will focus on identifying which components of brain energy balance matter most for recovery, exploring additional strategies that could complement this approach, and determining whether similar methods could work for other long-term, age-related neurodegenerative diseases as well.

Adenovirus Cases Rise In UK, Health Authorities On Alert

Updated Dec 25, 2025 | 09:08 PM IST

SummaryAfter a harsh superflu season, adenovirus has emerged as a fresh concern in the UK. The highly contagious virus causes cold or flu-like symptoms but can trigger stomach illness and complications. Though there is no specific treatment, hygiene helps. Reassuringly, recent lab data shows adenovirus cases are currently declining nationwide overall now.

Adenovirus, or what some people are calling the mystery disease is going to be the next worry in the UK, after superflu had already grappled the healthcare system. Along with H3N2 and its variant superclade K, people are now worrying about this mystery disease.

Adenovirus is highly contagious and causes mild cold or flu-like symptoms, though severe cases could lead to stomach flu and vomiting. Many describe this virus as 'heartier' than others. The reason is that the virus can survive longer on surfaces and even resist the common disinfectants used. This is what makes it highly transmissible.

Is There Any Treatment For Adenovirus?

As of now, there is no treatment for adenovirus, it could however be managed and monitored. What helps is regular handwashing and thorough cleaning of surfaces.

The good news is that cases of adenovirus are actually dropping in the UK, as confirmed lab reports. The cases last week were 1.2 per cent, whereas the week prior, it was at 1.7 per cent, as also reported by the Independent.

What Are The Symptoms Of Adenovirus?

While a lot of the symptoms mimics of those in flu or COVID, including shortness of breath, a sore throat and or a runny nose. However, there are certain unique symptoms of adenovirus that include:

  • Diarrhea
  • Pink Eye or conjunctivitis
  • Ear infection or otitis media
  • Swollen lymph nodes
  • Pneumonia
  • Stomach pain
  • Nausea
  • Vomiting

Other rare symptoms could also include impact on your bladder or nervous system. As viruses in your bladder can also cause urinary tract infections, and the same virus in your nervous system can cause condition that can affect your brain. These conditions also include encephalitis and meningitis.

The symptoms usually start to subside within two days, however, if the symptoms stay even after three days without any relief, it might be a red flag. The best thing to do during such a situation is to go consult your GP.

Is Adenovirus Spreading Faster Than Flu and Covid?

Experts have noted that due to its ability to stay longer in the environment and being highly transmissible, it is in fact, spreading faster than flu and COVID. Eric Sachinwalla, Jefferson Health's medical director said that this virus is still unfamiliar and thus not much can actually be done to treat adenovirus. Speaking to PhillyMad, he said, "It is pretty contagious because it is heartier than other viruses - soap and water, or everyday disinfectant, won't kill it, so it tends to live in the environment longer."

What Are The Ways To Stay Safe From Adenovirus?

Since adenovirus spreads through close contact and is resistant to many everyday disinfectants, hygiene remains the key. The best way to stay safe is by avoiding close contact, especially with those who are unwell. You may also keep an eye on your symptoms, including your body temperature and take steps to prevent the virus from spreading by taking precautions, as well as getting the flu jab.
