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.

India has recorded 6,927 dengue cases and 10 deaths so far in 2026, according to the latest data from the National Centre for Vector Borne Diseases Control (NCVBDC).
According to the provisional data as of February this year, Tamil Nadu reported the highest number of cases at 2,873, followed by Maharashtra with 786, Kerala with 670, Karnataka with 560, and Andhra Pradesh with 448 cases. During the same period, Kerala reported nine deaths, while Tamil Nadu reported one death.
According to the Ministry of Health, the Case Fatality Rate (deaths per 100 cases) for dengue has remained below 1 per cent since 2008 and stood at 0.13 per cent in 2024.
The dengue burden in India has steadily increased over the past few years:
| Year | Cases | Deaths |
| 2021 | 193,245 | 346 |
| 2022 | 233,251 | 303 |
| 2023 | 289,235 | 485 |
| 2024 | 233,519 | 297 |
| 2025 | 121,824 | 131 |

National Dengue Day: History And Theme
Launched in 2010, National Dengue Day is observed every year on May 16 as a pre-monsoon alert to help communities prepare before mosquito breeding peaks.
“On National Dengue Day, let us unite to spread awareness about dengue prevention and keep our surroundings clean and safe. The Government of India continues to strengthen dengue control through better surveillance, testing, improved treatment, and awareness campaigns,” said Jagat Prakash Nadda on the social media platform X.
“This year’s theme, ‘Community Participation for Dengue Control: Check, Clean and Cover,’ reminds us that community action is key to defeating dengue,” he added.
Dengue Vaccines In India

Notably, India is currently developing an indigenous dengue vaccine that is undergoing clinical trials.
“The trials will take at least two and a half years, which means by the end of 2028, we will have the results,” said Dr. N K Arora, Member of the National Technical Advisory Group on Immunization in India (NTAGI), speaking to HealthandMe.
He highlighted the severity of dengue when it progresses from a mild illness to a severe one, particularly among young adults.
The vaccine is expected to play a crucial role in protecting the 10–20 age group, which is considered more susceptible to severe dengue cases.

“We are waiting for the results of the trials, and once the vaccine is recommended by the NTAGI, the system will be ready to adopt it,” Dr. Arora added.
Meanwhile, Qdenga, a dengue vaccine developed by the Japanese pharmaceutical company named Takeda Pharma, is expected to be rolled out soon in the country.
The vaccine TAK-003 will be available in India through a manufacturing partnership with Hyderabad-based Biological E (Bio E), in line with the 'Make in India' initiative.
Dengue is a viral infection transmitted primarily by Aedes mosquitoes and is common in tropical and subtropical regions worldwide.
Mild dengue causes high fever and flu-like symptoms. However, in some cases, it can progress to severe dengue, also known as dengue hemorrhagic fever, which may lead to serious bleeding, shock, and death.
Dengue is considered the most prevalent viral infection transmitted by Aedes mosquitoes. More than 3.9 billion people across over 132 countries are at risk, with an estimated 96 million symptomatic cases and around 40,000 deaths annually worldwide.
Symptoms usually appear 4–10 days after being bitten by an infected mosquito and may vary in severity. Common symptoms include:
In severe cases, dengue may cause excessive bleeding, a sudden drop in blood pressure, and organ complications.
Preventing dengue mainly involves reducing mosquito exposure and eliminating mosquito breeding sites. Effective preventive measures include:

While alcohol consumption is known to be harmful to health, a new study has linked it to 62 disorders ranging from heart and digestive diseases to mental and neurological conditions and cancers.
The study, published in the journal Addiction, showed that the fully alcohol-attributable conditions are mainly grouped under non-communicable diseases and injuries. These include endocrine, nutritional, and metabolic diseases, mental and behavioral disorders, diseases of the nervous system, diseases of the circulatory system, such as alcoholic cardiomyopathy, and digestive diseases, including alcoholic liver disease and cirrhosis.
The latest data also adds psychotic disorders, gastritis, ulcers, pancreatitis, fatty liver disease, pregnancy- and perinatal-related conditions such as fetal alcohol syndrome and fetal alcohol spectrum disorders, as well as external causes and injuries, including alcohol poisoning.
“These conditions are 100 per cent alcohol attributable, meaning these diseases would not even exist in the world without alcohol use,” said Jürgen Rehm, senior scientist at the Institute for Mental Health Policy Research in Toronto and part of the study team, according to CNN.
“There are another 30 diseases in which alcohol plays a role, such as breast and other cancers, heart disease, stroke, diabetes, and dementia,” Rehm said. “These diseases would exist even without alcohol use, but alcohol use is responsible for a certain proportion of them.”
The diseases and injury categories fully attributable to alcohol were identified using the World Health Organization (WHO) International Statistical Classification of Diseases and Related Health Problems, 10th (ICD-10) and 11th (ICD-11) revision databases.
The study defines heavy drinking as more than 40 g of pure alcohol a day for women and 60 g a day for men. This translates to about 1.4 ounces of liquor for women and 2.1 ounces for men.
The good news, researchers said, is that many of these health effects can be slowed, stopped, or even reversed.
“Fortunately, the immediate effects of alcohol on the immune system don’t last long. Depending on levels of consumption, the body bounces back within days to a week,” Rehm said.

In 2025, former US Surgeon General Dr. Vivek Murthy released a new Surgeon General Advisory on alcohol and cancer risk, highlighting the direct link between alcohol consumption and increased cancer risk.
Similar to warning labels on cigarettes, the Surgeon General called for cancer risk warnings on alcohol products.
The report released by the US Surgeon General’s office identified at least seven types of cancer associated with alcohol consumption. It also recommended updating alcohol labels to include cancer warnings and reassessing guideline limits for alcohol consumption.
The cancers linked to alcohol consumption that Murthy recommended should be included on warning labels:

Amid India's growing burden of high blood pressure among the youth, Prataprao Jadhav, Union Minister of State (I/C), Ministry of Ayush and Minister of State for Health and Family Welfare, said hypertension is emerging as a major public health concern due to worsening lifestyle habits.
High blood pressure is a “silent killer” that is rapidly increasing among India’s youth because of unhealthy lifestyle changes, the minister said.
Ahead of World Hypertension Day 2026, Jadhav noted that the condition often progresses without visible symptoms and can eventually lead to severe complications such as heart attacks and strokes.
“In today’s time, it is essential that we make our communities more sensitive and aware and strengthen awareness about hypertension. Due to changing lifestyles and reduced attention to physical and mental health, hypertension is rapidly increasing even among the youth,” Jadhav said in a video message during the ‘Illness to Wellness Conference on Transforming Hypertension Care: Prevention to Wellness’ organized in the national capital.
He highlighted that the Government of India, under the National Program for Prevention and Control of Non-Communicable Diseases (NPCDCS), is actively promoting population-based screening, early detection, and management through Health and Wellness Centers across the country.
Prof. Rakesh Yadav, Cardiologist and head of the Department of Emergency Medicine at AIIMS, New Delhi, stated that once known to be the disease of the elderly, hypertension is now more common among the youth. The reason — lifestyle changes, the experts said.
“The biggest problem is that despite increasing awareness, people still do not monitor their blood pressure regularly or continue treatment consistently. Hypertension is no longer limited to the affluent or elderly; it is now affecting all sections of society, including children and young adults,” said Prof. Rakesh Yadav, Cardiologist and head of the Department of Emergency Medicine, AIIMS, New Delhi.
“Obesity remains one of the major underlying causes, and regular monitoring of blood pressure and sugar levels, affordable lifelong medication, healthy dietary practices, and weight management are essential to reducing mortality associated with hypertension and related diseases,” he added.
In India, more than 1 in 4 people have hypertension, and cumulatively, more than 90% of adults with hypertension are either undiagnosed, untreated, or treated but live with uncontrolled hypertension.
Experts at the conference also pointed out that modern lifestyles marked by long working hours, constant connectivity, poor sleep, sedentary habits, and rising stress levels are significantly contributing to the growing burden of hypertension and other lifestyle disorders.
Another major concern, they said, is that many people tend to ignore early symptoms until complications arise, negatively affecting treatment outcomes.
“Hypertension is one of the biggest public health challenges today because most people do not take it seriously until complications arise. Nearly one in four adults is affected by hypertension, yet awareness and blood pressure control remain very low,” said Dr. Ripen Gupta, Vice Chairman & Unit Head - Cardiology, Max Smart Super Speciality Hospital, Saket.
Rajesh Bhushan, Former Secretary, Ministry of Health & Family Welfare, said high blood pressure is not limited to urban populations and is increasingly affecting youth in rural India as well.
“The problem of hypertension is as prevalent in rural India as it is in urban India, but because we live in metro cities, we often believe it is only an urban problem. Early detection is extremely important because without early detection, early treatment becomes difficult,” Bhushan said.
Bushan stated that non-communicable diseases impact GDP significantly across countries, and therefore, prevention and timely intervention are critical.
Hypertension should never be taken lightly, said Dr. Sanjeev Singh, Chairperson, FICCI Medical Education Task Force and Medical Director, Amrita Institute of Medical Sciences & Research Centre. He urged people to follow medical advice seriously to avoid long-term complications.
The doctors called for critical lifestyle interventions for prevention and management. This included:
