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.

GLP-1 receptor agonist drugs such as Ozempic and Wegovy have shown significant benefits for people with diabetes and obesity. However, not everyone experiences the same results.
Now, a study suggests that this variation may be due to genetic resistance, which means that some people are biologically less responsive to these medications, making these drugs less effective.
The new study by scientists at Stanford University in the US showed that about 10 per cent of the general population carry genetic variants that lead to what the researchers called “GLP-1 resistance”.
The GLP-1- receptor agonist drugs typically work by mimicking the hormone GLP-1 (glucagon-like peptide-1), which naturally helps regulate blood sugar by stimulating insulin release. The process slows the emptying of the stomach and reduces appetite.
However, in individuals with certain genetic variants, the team found that higher levels of GLP-1 did not regulate blood sugar better.
The researchers noted that the findings, published in the journal Genome Medicine, may be key to developing new therapies for people with GLP-1 resistance.
“There are a whole class of medications that are insulin sensitizers, so perhaps we can develop medications that will allow people to be sensitized to GLP-1s or find formulations of GLP-1, like the longer-acting versions, that avoid the GLP-1 resistance,” said Anna Gloyn, professor of pediatrics and of genetics at Stanford Medicine.

To zero in on the gene resistant to GLP-1 drugs, the team conducted experiments in humans. They traced this resistance to a PAM variant known as p.S539W.
PAM (peptidyl-glycine alpha-amidating monooxygenase) is an enzyme that is uniquely capable of activating many hormones in the body, including GLP-1.
While the researchers suspected that people with the PAM variant would have lower levels of GLP-1 in their blood, it actually increased levels of GLP-1. Although the exact mechanism is still unclear, experiments in both humans and mice confirmed signs of reduced response to GLP-1.
Analyzing diabetes drug trial data, they found that individuals with these variants were less able to lower their blood sugar levels even after six months of treatment. This suggests that despite having more circulating GLP-1, their bodies are less responsive to it.
“When I treat patients in the diabetes clinic, I see a huge variation in response to these GLP-1-based medications and it is difficult to predict this response clinically,” said Mahesh Umapathysivam, an endocrinologist and clinical researcher at Adelaide University in Australia.
“This is the first step in being able to use someone’s genetic make-up to help us improve that decision-making process,” he added.

Importantly, participants with the PAM variants did not respond differently to other common diabetes treatments, including sulfonylureas, metformin, and DPP-4i.
The finding may help develop precision medicine, the researchers said. Knowing ahead of time who is likely to respond would help patients get on the right drugs faster, Gloyn said.
Ozempic is primarily indicated for type 2 diabetes management. But some doctors may prescribe it for weight loss in appropriate patients without diabetes.
Previous research has shown that medical conditions such as sleep apnea, along with certain common medications, such as antidepressants, steroids, and contraceptives, can hamper the process of shedding extra pounds.
Another major reason that can hamper weight loss is the side-effects of these drugs that can prompt a person to halt their prescription mid-way.

Once widely known as non-alcoholic fatty liver disease (NAFLD), the common and dangerous fatty liver condition was rephrased as Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) due to its strong link to metabolic health issues like obesity and diabetes.
MASLD now includes patients with fatty liver disease linked to metabolic risk factors such as obesity, diabetes, and hypertension.
Globally, it was observed that all patients who have non-alcoholic fatty liver disease also have some associated form of metabolic dysfunction. The patients reported having either obesity, diabetes, metabolic syndrome, hypertension, or cholesterol problems.
And all these problems eventually lead to significant comorbidities later, like some people developed heart disease, while others developed complications of diabetes.
In view of these, a global consensus process in 2023 involving hundreds of experts from different countries adopted MASLD as it better reflected these underlying causes of the condition.

MASLD is an umbrella term for liver conditions that develop in the presence of 1 or more cardiometabolic risk factors—including high blood sugar, elevated body mass index (BMI), and hypertension—but in the absence of other causes of liver fat accumulation.
The condition can be defined by excess liver fat accumulation (more than 5 per cent of liver weight) in the presence of metabolic dysfunction, independent of alcohol intake.
It encompasses a spectrum from simple steatosis to steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma.
“Initially, it was thought that having fatty liver disease without alcohol was a benign condition, but now it is recognized that, since it is associated with lots of metabolic comorbidities, it's no longer benign,” Dr. Ashish Kumar, Professor of gastroenterology and hepatology at Sir Ganga Ram Hospital in New Delhi, told HealthandMe.
He stated that whenever a diagnosis of fatty liver is present, "we should actually include other comorbidities, like obesity, dyslipidemia, which means cholesterol problem, diabetes, sugar problem, pre-diabetes, and hypertension. At least 50–70–80 percent of these patients will have one or more of these comorbidities".
Although alcohol has remained the number one risk for liver disease, MASLD seems to be rising globally, including among people who do not drink. Why?
The reasons include:
a sedentary lifestyle,
increased consumption of fast and processed food,
lack of exercise,
lack of sleep,
stressful life.

The experts noted that food, especially the increasingly accessible junk food or processed food, is a major culprit.
“So even if the person is not drinking alcohol, people are developing addiction to processed food, and this is causing an epidemic level of obesity and diabetes. Consequently, MASLD is also increasing, and now it is becoming the number one cause of liver disease,” Dr Kumar said.
According to Dr. Sanjay Goja, Director, Liver Transplant & HPB Surgery, Narayana Hospital, Gurugram, prevention must focus on following a healthy lifestyle like maintaining a healthy BMI, engaging in regular physical activity, and eating a balanced diet.
Controlling diabetes, cholesterol, and blood pressure is also important to prevent the risk of MASLD.
Dr Siddharth Badola, Manipal Hospital, Ghaziabad, suggested sustainable lifestyle changes such as:
Maintaining an adequate body weight: Even slight weight loss (5–10 percent) has been shown to significantly reduce liver fat and inflammation.
Follow a balanced and nutrient-rich diet: People should focus on consuming whole grains, fresh fruits and vegetables, lean proteins, and healthy fats, while limiting refined carbohydrates and processed foods.
Avoid foods with added sugar: Excess consumption of fructose, commonly found in packaged foods and sugary beverages, is a key contributor to fat accumulation in the liver.
Engage in regular physical activity: At least 150 minutes of moderate-intensity exercise per week is recommended to improve insulin sensitivity and liver health.
Manage associated metabolic conditions: Effective control of diabetes, hypertension, and dyslipidemia is essential in reducing the risk of MASLD progression.
Ensure adequate sleep and stress management: Poor sleep quality and chronic stress can negatively impact metabolic balance and liver function.
Keep your body hydrated with ample water intake and follow structured meal timings.
Heart attacks are now affecting younger people. (Photo credit: iStock)
Although a heart attack is generally considered a disease of the elderly, its incidence in young individuals is unfortunately on the rise. The reasons behind this are multifactorial. A heart attack is a condition where one of the arteries (blood vessels) suddenly becomes partially or completely occluded by a thrombus. Although the thrombus generally occurs suddenly, the underlying reason is a chronic process of lipid deposition in the vessel walls called atherosclerosis. Atherosclerosis can begin even in the first decade of life, but events like heart attacks conventionally occurred beyond 45 years in men and 55 years in women. On average, heart attacks occur in Indians about 10 years earlier than in their Western counterparts.
Dr Shyam Sasidharan, Consultant, Department of Cardiology, KIMSHEALTH Thiruvananthapuram, spoke about the early onset of heart attacks. From a population perspective, the rising number of heart diseases due to coronary artery disease (CAD) is significant not only because of its overall negative impact on the healthy population but also due to the potential for preventive interventions.
Acute coronary syndromes, or heart attacks, are on the rise among younger individuals, particularly in our country. Studies of the Asian-Indian migrant population have revealed a probable racial predisposition for premature CAD. However, the majority of the risk can still be attributed to the increased incidence of conventional CAD risk factors in young people, such as obesity, inactivity, diabetes, hypertension, and dyslipidaemia.
Smoking and substance abuse are resulting in more heart disease among the young. Lesser-discussed, unconventional risk factors, such as mental stress, lack of healthy employment practices, environmental pollution, and lack of proper food safety regulations, are in fact contributing significantly to this silent epidemic. COVID-19 infection as well as vaccination were widely attributed as causes of heart attacks in young people, but without adequate scientific evidence.
