Mold Exposure (Credit: Canva)
Mold is a type of fungus that has been found on the surface of the earth for millions of years. They can get inside your home through open doors, windows, and air conditioning systems. Inhaling mold spores or coming into contact with mold can have severe adverse effects on your health. Beyond physical symptoms like headache and allergic symptoms, it can have a significant impact on the brain and nervous system. Symptoms may vary, from mild headaches to more severe issues like memory loss or difficulty walking. While it can affect anybody, certain groups like children, the elderly, pregnant women, and those with weakened immune systems are particularly vulnerable to these effects.
How can mold impact your neurological health?
Mold, such as Cladophialophora bantiana, can cause infections in the brain and spinal cord, leading to serious conditions like central nervous system (CNS) infections. While such infections are rare, they can be life-threatening.
Mycotoxins are toxic chemicals produced by certain mold types. These toxins can be released into the air when mold grows indoors, and breathing them in can have direct harmful effects on brain function. Studies indicate that mycotoxins may interfere with the nervous system’s communication pathways, leading to cognitive issues such as memory problems and mood swings.
In fact, long exposure to mold can lead to a variety of neurological symptoms, which can differ depending on an individual’s health and the severity of the mold exposure. Some of them are:
Headaches are one of the most frequent symptoms of mold exposure. While most of the time, these headaches are described as dull, constant, or pressure-like, they can sometimes mimic migraines, accompanied by nausea or sensitivity to light and sound.
Exposure to molds can also trigger seizures. Mold produces toxic substances like mycotoxins that may disrupt the brain’s electrical activity, leading to seizure episodes.
Mold exposure can cause brain fog, which results in concentration, memory, and mental clarity. Studies suggest that mycotoxins can disrupt normal brain function, making it challenging to process information and think clearly.
Exposure to this fungus can also lead to emotional problems. People with this kind of exposure have complained of anxiety, depression, irritability, and sudden mood swings. This could be due to mold toxins interfering with brain chemicals responsible for regulating emotions.
Mold exposure may trigger inflammation, leading to muscle and joint pain. In case of prolonged exposure, it could lead to the development or worsening of fibromyalgia or complex regional pain syndrome (CRPS).
In some cases, mold exposure may lead to tremors, difficulty walking, or problems with muscle coordination. These issues may be linked to mycotoxins affecting the brain or nervous system.
Mold exposure can impact the brain areas responsible for movement and balance, making it harder to stand, walk, or perform fine motor tasks. Individuals may feel unsteady or experience difficulty using devices like phones or computers.
Delirium is a condition wherein a person experiences confusion or disorientation. An abnormal immune response to mold could contribute to this condition. Delirium can make it difficult for individuals to think clearly or understand their surroundings.

Deadly Nipah Virus Outbreak: Nipah virus outbreak reported in West Bengal, India started with the cases of two nurses, one of whom is in "critical condition". Nearly 100 people are quarantined, and India's Ministry of Health shared precautions to prevent Nipah virus infection in a post on X.
However, how did it all start?
The original infection was first identified in September 1998 in Perak, Malaysia, which was followed by second and third clusters in the state of Negri Sembilan, notes a 2021 study that tracks the evolution of the virus. The cases were prominent in adult men who were in contact with swine. By March 1999, a cluster of 11 similar cases were identified in Singapore, mostly common in slaughterhouse workers, who were in contact with pigs imported from Malaysia. This is how the virus started to become global. While people there were isolated, the outbreak in Malaysia continued to spread. This led to restrictions on swine imports to Singapore, followed by nationwide testing among pigs in Malaysia, and ultimately mass culling of over one million pigs from any farm in Malaysia with a confirmed infection.

Then appeared a new, distinct strain of Nipah virus with infection which was characterized largely by severe respiratory symptoms. In 2000-2001, Bangladesh and India were affected. Epidemiological studies revealed clustering around household members and hospital contacts without any clear animal exposure. This raised suspicion for human to human transmission.
When Nipah virus (NiV) was first identified, scientists noted that the closely related Hendra virus persisted in fruit bats of the Pteropus genus, raising early suspicions that these bats could also be the natural reservoir for NiV. Later research confirmed the presence of NiV genetic material and neutralising antibodies in urine, saliva, blood and various organs of several Pteropus bat species across Asia, including in countries with no recorded human cases.
This raised doubts, and it was later revealed that due to the consumption of raw date palm juice, the infection developed. This is because bats also are carrier of the virus and they may bite into raw fruits or lick them, and consuming juice from such fruits could spread the infection. This was a common practice in Bangladesh and much of South Asia.

Studies examining human exposure patterns found a strong link between NiV infection and the consumption of raw date palm sap. The sap, typically harvested between December and February, is often contaminated by bats that feed on it, leaving behind saliva and urine. In Bangladesh, this route has been identified as the main pathway of transmission from bats to humans, although the possibility of additional human-to-human spread remains.
In 2014, a serious outbreak of illness hit two villages in southern Philippines, with people developing brain infections, meningitis and flu-like symptoms. Tests later confirmed Nipah virus as the cause. Among those who developed acute brain infection, the death rate was extremely high at 82 percent. While some infections spread from person to person, this was the first outbreak linked to the slaughter of horses and the consumption of horse meat. Around the same time, several horses and other domestic animals that had eaten horse meat also fell sick and died.
In 2018, another outbreak occurred in Kerala, India, where 23 confirmed and suspected cases were reported. The virus spread across three hospitals, with both primary and secondary infections traced back to one initial patient. Samples collected from the patient’s home and workplaces, including pets and partially eaten fruits dropped by bats, all tested negative for the virus, and the exact source of the infection could not be identified.

Currently, two nurses, a doctor, hospital staff and some patients have reported to be infected by the virus. A survey conducted on bats in West Bengal found no active Nipah virus infection. Though there were antibodies detected in one specimen, which indicated prior exposure. This was confirmed by a senior state forest department official. The survey was conducted amid the identification of two confirmed Nipah virus cases.
To conduct the survey, nine bats near Kuberpur on the Kolkata-Barasat Road in Madhyamgram were tested using RT-PCR. All samples were negative, however, one bat, tested positive for antibodies. However, it only suggested prior infection, meaning there was no current risk of transmission.

The survey was conducted by the state forest department in collaboration with scientists form Pune-based National Institute of Virology. "The findings are reassuring, but caution is warranted. Surveillance and prevent measures will continue until we are fully assured that there is no risk," confirmed a senior official of the West Bengal Health Department.
As per the World Health Organization (WHO), Nipah virus infection is a zoonotic illness that is transmitted to people from animals, and can also be transmitted through contaminated food or directly from person to person.
In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers.
Although Nipah virus has caused only a few known outbreaks in Asia, it infects a wide range of animals and causes severe disease and death in people.

Your weight not only affects your heart health but also your brain health. A recent study published in the Journal of Clinical Endocrinology & Metabolism has revealed a powerful connection between your body weight, heart and brain.
After studying over 500,000 people, scientists discovered that having a high Body Mass Index (BMI) can nearly double your chances of developing brain-related illnesses later in life, which confirms that being overweight and having high blood pressure are not just general health concerns, they are direct causes of dementia.
The study focused heavily on vascular dementia, a specific type of memory loss that occurs when the brain is damaged because of a lack of blood flow.
Think of your blood vessels like a system of pipes. If those pipes are narrowed or blocked due to weight-related issues, the "engine" (your brain) doesn't get the fuel it needs. Over time, this lack of oxygen and nutrients leads to permanent brain damage and the loss of memory and thinking skills.
Researchers found that high blood pressure, often caused by carrying extra weight, is the main "middleman" in this process. Blood pressure is measured with two numbers, and both play a part in brain health:
This is the pressure when your heart beats. It accounts for about 18 percent of the link between obesity and dementia.
This is the pressure when your heart rests between beats. It accounts for about 25 percent of the link. When these numbers stay high, they constantly "batter" the delicate vessels in the brain, causing them to weaken or clog.
Beyond just blood flow, a high BMI impacts the brain in several other ways:
Obesity often causes the body to be in a constant state of "alarm" or inflammation. This can irritate the immune system and eventually damage brain cells.
When the body struggles to process energy and food properly, it changes how the brain uses energy, which can lead to cognitive decline.
A heart that has to work harder to pump blood through a larger body eventually becomes less efficient at sending blood all the way up to the brain. Your heart essentially has to do twice as much work as it would at a lower weight.
The most encouraging takeaway from this study is that dementia isn't always a matter of bad luck or "old age." Researchers call this an unexploited opportunity.
By managing your weight and blood pressure early in life, through a healthy diet, consistent exercise, and good sleep, you are essentially "dementia-proofing" your brain. The researchers suggested that intervening early, possibly even with weight-loss medications before symptoms start, could be a key strategy for protecting brain health in the future.
According to the World Health Organization, one in eight people in the world are living with obesity. In 2022, about 2.5 billion adults were overweight. Causes of it vary, from things like diseases or chronic conditions, to the kind of food that is available to consume.

Heart attacks need immediate intervention and Dr. Balbir revealed one medicine that can save a life when this happens: Aspirin. In an interview with HealthandMe, Dr. Singh revealed that one does not need fancy equipment to help a person having a heart attack.
“If the history of the family history or cholesterol or diabetic. This patient is at risk, so what is the medicine if you get such a symptom? Aspirin.”
Dr. Singh points out that if you or someone near you begins to experience symptoms of a heart attack, such as heavy chest pain, pressure, or unexplained sweating, taking a dissolvable aspirin immediately can be a lifesaver.
By dissolving a tablet (like Dispirin) in a glass of water and drinking it, the medicine dissolves into the bloodstream much more quickly than simply ingesting it.
Aspirin works by thinning the blood and preventing further clotting in the arteries, which can stop a heart attack from getting worse before medical professionals arrive.
Before medical professionals arrive, performing CPR can also help save a person's life; however, one must know the right way to do CPR.
While speaking to HealthandMe, Dr Singh mentioned a viral video where a person collapses and someone attempts to give them CPR while they are still sitting in a chair, notng that this was 'a dangerous mistake' and people should steer clear away from such false videos.
He explained that you cannot perform CPR on someone who is sitting up as the body must be positioned correctly for the heart and lungs to receive the benefit of the chest compressions.
Without the proper technique, blood will not reach the brain and your efforts will not help the patient. Understanding the proper sequence of events is the difference between a failed attempt and a saved life.
If someone collapses, immediately place them flat on their back on a hard floor. You need the ground's resistance to pump the heart manually. In this position, the heart is "sandwiched" between the rib cage and spine. On a soft bed, your presses will fail to squeeze the heart effectively.
Dr. Singh emphasizes that restarting the heart is the absolute priority. Place both hands in the center of the chest and use your body weight to press firmly. By pushing the rib cage toward the spine, you force the heart to pump. Often, once circulation starts, the patient begins breathing again spontaneously.
If the person doesn't wake up, begin a rhythm of three chest presses followed by one mouth-to-mouth breath. Lock your elbows and press hard to ensure the heart is being squeezed between the bones. This specific cycle keeps oxygenated blood moving to the brain, preventing permanent damage during a cardiac emergency.
According to the Centers for Disease Control and Prevention, heart attacks claim a life every 34 seconds. In 2023, it caused nearly 920,000 deaths, one in every three recorded. Hence it is important to know not just the ways to help when someone has a heart attack but also how to prevent them.
