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.

Insulin resistance is a condition in which the body cannot effectively use insulin. Shockingly, this condition is now being linked to first-trimester miscarriages, especially in women with PCOS, with lab markers such as HbA1c and fasting insulin offering early clues. Therefore, it is essential for women to take charge of their health and maintain their blood sugar levels within the recommended range, as per Dr Sushruta Mokadam, Senior Consultant Obstetrician & Gynaecologist, Motherhood Hospital, Kharadi, Pune. The expert went on to talk about other aspects of the same, detailing just how first trimester miscarriages could be a consequence of ignoring high blood sugar or insulin resistance.

Why are miscarriages in the first trimester rising?

Currently, there is a surge in cases of miscarriages during the first trimester, which is raising concern among experts. This may be due to undiagnosed insulin resistance. Yes, that’s right—miscarriage is not only caused by infections, hormonal imbalance, or blood clotting disorders, but also by insulin resistance. Many women fail to pay attention to insulin resistance, which affects how the body processes sugar and plays a major role in causing hormonal imbalance. Women with Polycystic Ovary Syndrome (PCOS) are at a higher risk, as metabolic dysfunction can lead to miscarriage. Many women are experiencing repeated early pregnancy loss but are not screened for insulin resistance, leading to missed opportunities for early intervention.

How are miscarriages and insulin resistance linked?

Miscarriage and insulin resistance link: Insulin resistance occurs when the body’s cells do not respond properly to insulin, leading to higher blood sugar and insulin levels. This imbalance can impact ovulation and egg quality and interfere with the implantation of the embryo. In early pregnancy, it may affect placental development, increasing the risk of miscarriage in the first trimester. In women with PCOS, insulin resistance is commonly present, even in those who are not overweight.

The impact of insulin resistance on reproductive health

High insulin levels can lead to increased androgen (male hormone) production, further affecting reproductive health. This hormonal imbalance can make it difficult for a pregnancy to be sustained, especially in the early weeks, which may result in miscarriage. Lab tests such as HbA1c (which reflects average blood sugar levels over time) and fasting insulin levels can help identify at-risk women. Even subtle elevations in these markers, including those within the upper-normal range, can indicate underlying metabolic dysfunction that may increase the chances of miscarriage.

What to do?

Pregnant women should opt for regular screening, manage blood sugar levels, eat a balanced diet, and exercise daily before planning pregnancy. Even during pregnancy, they should stay in touch with an expert who can guide them throughout the process.

Blood pressure is one of the most important, yet overlooked, aspects of a healthy individual. Little do people realise that the force at which blood presses against the walls of the arteries can have a serious impact on long-term health—heart attack or stroke, for instance. Current guidelines from the American Heart Association state that adults should aim for a blood pressure reading of 130/80 millimetres of mercury (mm Hg). Some experts also say that this target is a little too aggressive for people who are prone to the side effects of blood pressure medication, such as falls and dizziness. But what would be the ideal blood pressure reading for older adults? Harvard Health experts have just answered this question.

Blood pressure reading in the 60s

According to recent studies, an intensive reduction in blood pressure in people aged over 60 is not only safe but is also associated with better outcomes than less aggressive treatment. According to a 2025 review, four randomised controlled trials were compared using two different strategies to control systolic blood pressure. The first aimed for a lower target, while the other strategy aimed for a higher systolic pressure. The trial included 2,600 people aged 75 years and older. Compared with a less aggressive strategy, there was a 39 per cent reduced risk of heart problems such as heart failure, heart attack, or stroke. There was also a 45 per cent lower risk of heart disease-related deaths.

Additionally, researchers noted no differences in the rates of adverse events such as fractures, low blood pressure, cognitive decline, or falls. Upon expanding the analysis, the same conclusions held true for people aged 70 years and above.

Rising hypertension risk

The risk of hypertension rises significantly with age. Among ageing adults, it is known as essential hypertension, as it helps deliver a sufficient amount of blood to the brain. With age, the blood vessels become less flexible and stiffer. Therefore, to reach the brain, an extra push is needed—as a result, systolic blood pressure can rise to as high as 150 mm Hg in people aged 65 years and above.

Doctors, however, are reconsidering their approach to hypertension treatment in older adults. The recent findings suggest that many older people should aim to keep their systolic pressure below 130 mm Hg. This may require a combination of lifestyle changes and medication.

Can one medication work?

According to experts, one medication may not be sufficient to achieve ideal blood pressure. A single drug usually works well to lower blood pressure by an average of 5 to 10 points. Using a lower dose of two different blood pressure medicines is more effective than maximising the dose of one drug. This approach is also less likely to result in side effects.

The relationship between chronic stress and liver health is a complex physiological loop driven largely by cortisol, the body’s primary stress hormone. While the liver is often viewed as a detox organ, it is highly responsive to hormonal signals, especially during prolonged stress. But at a time when competition is at its all-time peak in every aspect of life, be it work or school, it is a no-brainer that stress levels are peaking across age groups. That being said, Dr. Tushar Madake, Consultant, Department of Transplant Hepatology at Ruby Hall Clinic, Pune, spoke about the impact of high cortisol on the liver.

What is cortisol?

When stress becomes chronic, the adrenal glands continuously release cortisol. The liver, rich in glucocorticoid receptors, responds by shifting into a survival mode. In short-term situations, this helps by releasing glucose into the bloodstream for quick energy. However, when stress persists without physical activity, this constant signal disrupts normal metabolism.

The impact of high cortisol levels

One major effect is increased glucose production, where the liver generates sugar from non-carbohydrate sources. Over time, this leads to consistently high blood sugar and forces the pancreas to produce more insulin, eventually contributing to insulin resistance. At the same time, cortisol promotes the release of fatty acids into the bloodstream. The liver absorbs these fats but struggles to process and export them efficiently, leading to elevated triglycerides and unhealthy cholesterol levels.

How does stress affect the liver?

Stress also drives fat storage in the abdominal region and within the liver itself. This can result in fatty liver disease, even in individuals without poor dietary habits. As fat accumulates, inflammation follows. Liver immune cells release inflammatory substances, creating oxidative stress that damages liver cells. Additionally, when the liver is overloaded with managing excess glucose and fat, its ability to detoxify the body declines. Hormone balance, toxin clearance, and medication metabolism are all affected.

Stress can also impair bile flow, which is essential for fat digestion and toxin removal. Reduced bile movement further worsens internal imbalance. Ultimately, chronic stress keeps the liver in a constant state of overdrive, leading to long-term metabolic strain, inflammation, and gradual liver dysfunction.
