Daytime Sleepiness (Credit: Canva)
Experiencing daytime sleepiness is something that is usually perceived as a minor inconvenience, but for older adults, it could be an early warning sign of Dementia. This neurodegenerative disease leads to the progressive decline of brain cells. This eventually
affects memory, cognition, and personality, making everyday tasks more difficult. As one of the fastest-growing neurological disorders across the world, dementia poses a significant health threat to ageing populations.
For this study, researchers followed 445 older adults (average age 76) over three years, aiming to determine whether poor sleep could increase the risk of mild cognitive impairment (MCI), which often leads to dementia. At the start, none of the participants had MCI, but by the end of the study, 36 individuals had developed the condition.
The researchers discovered that participants with poor sleep were more likely to develop MCI compared to those who slept well. However, when depression symptoms were taken into account, the link between poor sleep and MCI became less pronounced, suggesting that while sleep issues are a concern, mental health also plays a key role in dementia risk.
To assess sleep quality, the Pittsburgh Sleep Quality Index (PSQI) was used, evaluating factors such as sleep duration, disturbances, and daytime alertness. Among these, "daytime dysfunction"—defined as excessive sleepiness and low energy during the day—was most strongly associated with an increased risk of MCI. Those experiencing daytime dysfunction were more than three times as likely to develop MCI as those who didn’t report such symptoms.
There are many types of dementia:
Dementia is not a specific disease. According to the Centers for Disease Control and Prevention (CDC), it is an overall term that describes a decline in mental ability that interferes with daily life. People with dementia often have symptoms like trouble remembering, thinking, or making everyday decisions. These symptoms tend to get worse over time.
Alzheimer’s disease is the most common type of dementia, and it mostly affects the elderly. Each form of dementia has a different cause. Though dementia mostly affects older adults, it is not a part of normal ageing. An estimated 6.7 million older adults have Alzheimer's disease in the United States. That number is expected to double by 2060, as per data from the CDC.
In 2022, 3.8% of men and 4.2% women in US were diagnosed with dementia. The percentage of people increase with age from 1.7% for those aged 65-74 to 13.1% for those aged 85 and older. Alzheimer's accounts for 60 to 80% of all dementia cases and it is most prevalent in California, Florida, and Texas, as these states have the highest number of people.

Even after recovery, the deadly Ebola virus (EBOV) can persist for a longer duration — more than three months — in breastmilk, according to a case report.
Ebola virus disease (EVD) is a severe viral illness that has a 25 percent – 90 percent fatality rate.
Ebola in pregnancy raises significant complications ranging from spontaneous abortion to maternal and neonatal death.
In a case report published in the New England Journal of Medicine, a team of researchers from the Republic of Congo and Senegal shared the case history of a 23-year-old woman in whom Ebola was still detectable in breast milk at 14 weeks.
The case reported the rare occurrence of a pregnant woman who survived EVD with no complications, neither to the mother nor the baby. However, the deadly virus was still present in the mothers' breast milk, which cited the potential risk of post-illness transmission to infants.
As per the World Health Organization (WHO), EVD is a rare but severe illness in humans and is often fatal.
People can get infected with the virus if they touch an infected animal when preparing food, or touch body fluids of an infected person such as saliva, urine, feces or semen, or things that have body fluids of an infected person like clothes or sheets.
Ebola enters the body through cuts in the skin or when one is touching their eyes, nose or mouth. Early symptoms include fever, fatigue and headache.
The woman from the Democratic Republic of the Congo (DRC) contracted EBOV during pregnancy in 2019.
Soon after, she was administered monoclonal antibody therapy and was discharged after three negative reverse-transcriptase–polymerase-chain-reaction blood tests for EBOV.
The woman delivered a healthy baby at 42 weeks of gestation. No evidence of EBOV infection was found in maternal blood, amniotic fluid, vaginal secretions, or the newborn.
Yet surprisingly, the EBOV virus persisted in the placenta and breast milk.
Tests revealed that while the mother’s blood remained negative, viral RNA was still detectable in breast milk at 14 weeks after illness onset. To protect the newborn from transmission, clinicians used the drug bromocriptine to suppress lactation.
As per the World Health Organization (WHO) guidelines, the mother was also isolated from the baby and not breastfed. A prophylactic (preventive) monoclonal antibody was also given to the newborn. During follow-up, the infant exhibited no signs of infection.
During the 2018–2020 EVD outbreak in the northeast of DRC, 3,481 confirmed cases were reported. Of these, nearly 60 percent occurred in females, and about 45 percent occurred in children below 18 years of age.
Current WHO guidance recommends that Ebola survivors avoid breastfeeding until viral clearance is confirmed.
The global health body advises women with suspected or confirmed Ebola to immediately stop breastfeeding and be prioritized for diagnostic testing.

Meningitis – the inflammation of the brain and spinal cord lining – has claimed 259,000 lives worldwide in 2023, according to a new study, published in The Lancet Neurology.
A total of 2.5 million people globally were infected with meningitis, which is also the leading infectious cause of neurological disabilities.
Importantly, children accounted for a third of the deaths, many of which were in Africa, according to research that described itself as the most comprehensive global assessment of meningitis yet.
The study comes amidst a “unprecedented” meningitis outbreak in the UK’s Kent, where two people died, and many were infected.
According to the study, global vaccination campaigns since 2000, played a significant role in reducing the number of infections and deaths by bacterial meningitis, in both high-income and low-income countries.
The Global Burden of Disease study led by an international team of researchers led by those from the University of Washington, showed that although mortality and incidence have declined significantly since 1990, progress is insufficient to meet the WHO 2030 targets.
The WHO targets a 50 percent reduction in meningitis infections and 70 percent reduction in deaths by 2030. However, a substantial meningitis burden persists. It also lags behind other vaccine-preventable diseases.
The driving factor are:

Meningitis is a serious medical condition that affects the protective membranes covering the brain and spinal cord, the meninges. While fever is not always present, it is usually considered as one of the classic symptoms of meningitis.
It is important to know the varied symptoms, causes, and treatments of meningitis for early diagnosis and proper management of the disease.
Meningitis is an infectious illness that brings about inflammation in the meninges. The most common cause of such inflammation is bacterial or viral infections, though other causes are also possible including fungal, parasitic, or non-infectious causes (autoimmune disease, head injury, or brain surgery).
Meningitis may also be caused by bacterial meningitis, which the Centers for Disease Control and Prevention (CDC) indicates can be so severe and bring about conditions like hearing loss, vision problems, and death if not received on time.

As per the Lancet study, the greatest risk factors for deaths was
Streptococcus pneumoniae, Neisseria meningitidis, non-polio enteroviruses, and other viruses were the leading causes of death, while non-polio enteroviruses caused the most cases.
To achieve further reductions in the disease globally, the researchers called for greater efforts, including:

World Doctors’ Day is celebrated every year on March 30 to honor physicians for their dedication and compassion in saving lives and ensuring healthy communities.
Doctors are often regarded as God as they work tirelessly to save lives, even amidst conflicts or pandemics, without counting their own lives.
Often referred to as a noble profession, their mission transcends boundaries and also showcases profound human values rooted in compassion, dedication, and responsibility.
They play a significant role in building resilient, healthy societies and the world.
While there is no universally declared theme to mark the day, several campaigns are held focusing on the well-being and resilience of doctors, especially in the post-pandemic era.
World Doctors’ Day is the same as US National Doctors Day.
It was first observed in 1933 in Georgia and officially recognized in 1990 when George H. W. Bush signed it into law.
The first Doctors' Day was initiated by Eudora Brown Almond, wife of Dr. Charles B. Almond, and was adopted by the Barrow County Alliance.
The day was also observed to mark the anniversary of the first use of general anesthesia in surgery by Dr. Crawford W. Long in Jefferson, Georgia, in 1842.
The idea was then presented to the Georgia State Medical Alliance in 1933 by E. R. Harris of Winder, president of the Barrow County Alliance.
On May 10, 1934, the resolution was adopted at the annual state meeting in Augusta, Georgia.
Later, it was resolved by the Senate and House of Representatives of the US in Congress to designate March 30 as “National Doctors’ Day.”
The symbol for Doctors' Day is often the red carnation, chosen for its color that represents love, charity, and sacrifice — that highlights the profession.
The US reportedly has over 985,000 to 1 million practicing physicians.
The day honors physicians' commitment, service, and contributions to healthcare, often highlighting their role in patient care. Their role is also in medical innovations that have given life to people across the globe.
It also highlights challenges faced by the physician community, like burnout, workforce shortages, and rising health demands.
Doctors are also overburdened with increasing patient load and staff shortages. Some also face workplace violence and safety concerns.
Notably, digital healthcare and evolving technologies have also added pressures and an additional burden to their practice.
World Doctors’ Day is celebrated on March 30 in the US, the UAE, and Australia.
India celebrates National Doctors’ Day on July 1, commemorating the birth and death anniversary of renowned physician Dr. Bidhan Chandra Roy.
