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.

English actor and former Blue Peter presenter Peter Duncan recently urged health authorities to make focal therapy more available for prostate cancer patients. He said after describing the treatment as "life-changing" following his own diagnosis in 2019.

This comes as new evidence has been emerging that the minimally invasive approach can offer satisfactory cancer control compared to traditional treatments, while also significantly reducing long-term side effects.

The 72-year-old broadcaster revealed that he was initially offered a prostatectomy, a surgery that removes the entire prostate gland. Instead, he opted for focal therapy, a targeted treatment that destroys only the cancerous portion of the prostate while preserving healthy tissue.

"It was a complete success, and I've only experienced very minor after-effects, allowing me to continue with my life as before," Duncan said, while backing Prostate Cancer UK's campaign for wider NHS access to the treatment. "Many men aren't given the same chance I was, and that needs to change."

Duncan's campaign comes amid growing clinical evidence supporting focal therapy for selected patients with localised prostate cancer.

A recent report from researchers at Imperial College London and Imperial College Healthcare NHS Trust found that focal therapy shows promise in cancer treatment compared to surgery and radiotherapy while causing far fewer complications in some patients.

Amy Rylance, Director of Health Services, Equity and Improvement at Prostate Cancer UK, said the delay in wider approval is leaving thousands of men with no access to treatments that could preserve their quality of life.

"Without a timeline from NICE, we simply don't know how long men will have to wait for approval on the NHS," she said. "Thousands of men will have to deal with life-changing side effects simply because of their postcode."

Unlike prostatectomy or radiotherapy, focal therapy targets only the tumour inside the prostate. The treatment may use high-intensity focused ultrasound (HIFU) or cryotherapy to destroy cancer cells while preserving the surrounding healthy tissue.

Because the rest of the prostate and surrounding nerves are preserved, patients may generally face a much lower risk of urinary incontinence, erectile dysfunction and bowel problems.

Focal therapy is not suitable for everyone. Specialists say it is generally considered for men with localised, clinically significant prostate cancer where imaging and biopsy show that the tumour can be accurately targeted.

Patients still require long-term monitoring after treatment to ensure the cancer has not returned or progressed.

Can Focal Therapy Help?

Prostate cancer is the most commonly diagnosed cancer in men in the UK. According to Prostate Cancer UK, around one in eight men will be diagnosed during their lifetime, with the risk increasing with age, family history and Black ethnicity.

While surgery and radiotherapy remain the standard treatment options to treat prostate cancer, advocates argue that expanding access to focal therapy could help thousands of eligible men receive effective treatment with fewer long-term side effects.

Duncan hopes sharing his own experience will encourage both policymakers and patients to consider the option where appropriate.

Maharashtra's Homeopathy Rule Explained: Why The IMA Is Protesting

Updated Aug 6, 2026 | 02:00 PM IST

SummaryEven as the matter is sub judice, the MMC began registering CCMP-qualified practitioners on August 5. According to reports, one practitioner has been registered so far, while around 2,500 applications remain pending.
Maharashtra's Homeopathy Rule Explained: Why The IMA Is Protesting

In a first for India, Maharashtra has allowed qualified homeopathy practitioners to prescribe certain modern medicines after completing a one-year Certificate Course in Modern Pharmacology (CCMP).

The decision has sparked strong opposition from the Indian Medical Association (IMA) and several doctors' bodies, which have announced protests, citing concerns over patient safety, medical education, and professional standards.

What Is The Debate All About?

Under a Government Resolution (GR) issued on August 3, Maharashtra has allowed BHMS graduates who have completed the one-year Certificate Course in Modern Pharmacology (CCMP) to register with the Maharashtra Medical Council (MMC). The registration allows eligible practitioners to prescribe specified modern medicines under the state's policy.

The MMC began registering CCMP-qualified practitioners on August 5. According to reports, one practitioner has been registered so far, while around 2,500 applications remain pending.

The IMA has warned of a nationwide strike if the Maharashtra government does not withdraw its decision. In a letter to Maharashtra Chief Minister Devendra Fadnavis, signed by IMA National President Dr. Anilkumar J. Nayak and Secretary General Dr. Sarbari Dutta, the association demanded immediate withdrawal of both the GR and the CCMP course.

Why Is the IMA Objecting?

The IMA has raised the following concerns:

  • No approval from national regulators:
The association said the CCMP course is not approved by the National Medical Commission (NMC) or the National Commission for Homoeopathy (NCH). "Such a course is against the principles of Medical Education and should be cancelled and discontinued with immediate effect."

  • Opposition to dual registration:
The IMA said allowing practitioners to be registered under two systems of medicine is unprecedented in India. "It is neither well thought out nor justified. There are no guidelines or SOPs laid out for the same. It also creates misinformation amongst the general public about the qualifications and capabilities of the doctor in treating their ailments."

  • Matter pending before the court
The association noted that the issue is sub judice before the Mumbai High Court and argued that registrations should not proceed while legal questions remain unresolved.

  • Concerns over medical education
The IMA said equating MBBS graduates with CCMP-trained practitioners undermines medical education. "The hard work and efforts of the students getting admission to MBBS are in vain and it is a tragic situation if they are equated with CCMP doctors who have done a part-time course."

What Is the CCMP Course? Why Was It Introduced?

The Certificate Course in Modern Pharmacology (CCMP) is a one-year program introduced in Maharashtra in 2016 by the Maharashtra University of Health Sciences (MUHS). It is designed for BHMS (Bachelor of Homeopathic Medicine and Surgery) graduates and trains them in aspects of modern pharmacology and allopathic medicine.

The CCMP course was introduced following a major agitation by homeopathic associations, including a 13-day indefinite hunger strike in Nagpur in 2013, demanding legal rights to prescribe essential modern medicines.

According to the Maharashtra government, the objective was to strengthen healthcare delivery, particularly in areas facing shortages of doctors.

To facilitate the course, the state amended the Maharashtra Homoeopathy Practitioners' Act, 1960 and the Maharashtra Medical Council Act, 1965 in 2014, after the legislation was passed by both Houses of the State Legislature.

The IMA now argued that the situation in 2014 when the MMC Act was amended is very different from the situation now.

The medical body cited the cancellation of "bond system for MBBS graduates due to the nonavailability of vacant posts for them even in rural areas- signifying sufficient availability of MBBS doctors".

What Does the CCMP Course Include?

According to the government, the one-year CCMP curriculum was developed by expert committees at MUHS after comparing the BHMS and MBBS syllabi to bridge gaps in training.

The course includes:

  • Training in modern pharmacology
  • Practical laboratory procedures
  • Rotational hospital training in clinical subjects of allopathy
  • Teaching at government and private medical colleges
  • Examinations conducted by the Faculty of Medicine, MUHS

The government says the program is intended to make registered homeopathic practitioners competent to prescribe specified modern medicines and improve access to healthcare in the state.

But the IMA has argued that such "short-term certification or bridge courses cannot substitute for comprehensive medical education". They also warned that permitting cross-practice would compromise patient safety.

What's Next?

The Maharashtra Association of Resident Doctors (MARD) began an indefinite statewide strike on August 3. On August 5, doctors across Mumbai withdrew routine outpatient department (OPD) services in protest against the government's decision.

Doctors from Pune are scheduled to join their counterparts in Mumbai for demonstrations at Azad Maidan on August 6. The IMA has warned of a nationwide strike if the Maharashtra government does not withdraw the decision. The IMA Kerala State Branch has also extended support to the Maharashtra doctors' protest.

Severe COVID-19 Can Reactivate Dormant Viruses, May Fuel Long COVID Symptoms: Study

Updated Aug 6, 2026 | 01:00 PM IST

Summary The Nature study found that viral reactivation frequently occurred in people who were healthy before developing COVID-19. It led to an increase inflammation, worsened tissue injury, and prolonged recovery.

A severe COVID-19 infection may awaken dormant viruses that remain hidden in the body for life, even in people with otherwise healthy immune systems, according to a study published in Nature.

The study, which analyzed more than 1,100 hospitalized COVID-19 patients, found that viral reactivation was common and may contribute to long COVID symptoms. Researchers said the findings suggest COVID-19 can disrupt the body's internal ecosystem of dormant viruses, creating a state they describe as "dysvirosis."

"This finding suggests that COVID-19 may not always act as a single viral infection and may disrupt the body's internal ecosystem of dormant viruses, creating a state of 'dysvirosis'," said lead author Cole Maguire from Dell Medical School at The University of Texas at Austin.

Which Dormant Viruses Were Reactivated?

Nearly half of the hospitalized patients had at least one dormant virus reactivate during their COVID-19 illness. The viruses identified included:

  • Epstein-Barr virus (EBV), which causes mononucleosis
  • Herpes family viruses
  • Enteroviruses
  • Cytomegalovirus (CMV)
  • Herpes simplex virus-1 (HSV-1)
  • Human herpesvirus-6 and -7 (HHV-6/7)
  • Anelloviridae, a lesser-known family of chronic viruses

How Viral Reactivation Affects The Body

The researchers found that viral reactivation was more common in patients with severe COVID-19 and those who had longer hospital stays, and caused:

  • Increase inflammation
  • Worsened tissue injury
  • Prolonged recovery

The study also noted that these viruses have previously been linked to autoimmune conditions such as multiple sclerosis and lupus.

Further, the study found that dormant viruses do not reactivate simultaneously after SARS-CoV-2 infection.

  • Epstein-Barr virus and anelloviruses tended to reactivate early, shortly after hospital admission.
  • Cytomegalovirus and herpes simplex viruses generally emerged around three weeks later, primarily in the respiratory system.

Not Limited to People With Weak Immune Systems

Earlier research had mainly observed viral reactivation in people with weakened immune systems. However, this study found that reactivation frequently occurred in people who were healthy before developing COVID-19.

According to the researchers, this suggests viral reactivation may be more common than previously believed and could contribute to worse outcomes even in otherwise healthy individuals.

While the study does not prove that viral reactivation causes long COVID, it provides strong evidence that dormant viruses may contribute to the condition.

Researchers found that Anelloviridae appeared more frequently in patients with long COVID who experienced persistent fatigue and reduced physical function.

"Our findings have important implications for patient care. Tests already exist for several of the chronic viruses studied, and some viruses in the herpes family can be treated with existing antiviral drugs," said study principal investigator Melamed, assistant professor of neurology at Dell Medical School.

"The next step is determining whether identifying and treating reactivated viruses can improve outcomes for patients with acute COVID-19 and long COVID."

The study may also influence future treatment strategies. Researchers noted that, instead of targeting only SARS-CoV-2, clinicians may eventually be able to use existing antiviral drugs against reactivated viruses, particularly herpesviruses.

A Phase II clinical trial is already underway to evaluate antiviral therapies targeting herpesviruses in people with long COVID.
