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.

Metabolism-Associated Fatty Liver Disease (MAFLD) — also termed Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) — is defined by excess hepatic fat accumulation (>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.

MAFLD: Epidemiology In India

A Lancet Regional Health study found that approximately 39 per cent of Indian adults screened had fatty liver disease, making it one of the most prevalent chronic liver conditions in the country. Within India, prevalence shows regional variation driven by genetic, dietary, and socioeconomic factors.

A particularly important feature is the “lean MAFLD” phenotype — South Asians often develop fatty liver at a lower BMI due to disproportionately high visceral fat, which complicates detection based on conventional BMI screening. Currently, MASLD is the commonest cause of liver cirrhosis and hepatocellular carcinoma (HCC).

MAFLD: Causes And Risk Factors

The core drivers are components of metabolic syndrome: type 2 diabetes mellitus, obesity (particularly central adiposity), dyslipidemia, hypertension, and insulin resistance. MASLD is strongly linked to obesity, sedentary lifestyles, and metabolic syndrome.

Genetic susceptibility also plays a role — variants in genes such as PNPLA3 are associated with increased liver fat accumulation, particularly in certain Indian populations. Rapid dietary transition towards ultra-processed, high-calorie foods compounds the risk.

MAFLD: Investigations

Routine liver function tests may appear normal in early stages, and an ultrasound detects only moderate-to-severe fat accumulation. A structured approach includes:

• Blood tests: LFTs, fasting glucose, HbA1c, lipid profile, insulin resistance indices
• Ultrasound abdomen: First-line imaging for steatosis
• FibroScan (Transient Elastography): Liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) are standardized non-invasive tools for assessing fibrosis and steatosis.
• Liver biopsy: Gold standard for staging steatohepatitis and fibrosis when non-invasive tests are inconclusive.

MAFLD: Treatment

No approved pharmacotherapy exists exclusively for MAFLD; management is lifestyle-centred:

• Weight loss: 7–10 per cent body weight reduction significantly reduces hepatic steatosis and inflammation
• Diet: Mediterranean-style diet; restrict refined carbohydrates and saturated fats
• Exercise: Both aerobic and resistance training improve insulin sensitivity and liver fat
• Metabolic comorbidity control: Optimise glycaemia (GLP-1 agonists show hepatic benefit), manage dyslipidaemia and hypertension
• Emerging therapies: Resmetirom (thyroid hormone receptor-β agonist) has shown promise in MASH with fibrosis.

Parkinson’s Disease is traditionally characterized by motor symptoms such as tremor and dyskinesia, although non-motor symptoms, in particular gastrointestinal (GI) symptoms such as constipation and incomplete emptying, are often the first markers of the disease and may precede the motor symptoms by years.

GI dysfunction is reported in approximately 70-80 per cent of Parkinson’s patients, mediated in large part through the gut-brain axis (GBA).

Speaking to HealthandMe, Dr Paresh Doshi, Director of Neurosurgery and Stereotactic and Functional Neurosurgery at Jaslok Hospital and Research Center, GBA, is an established two-way network that links the GI tract and the central nervous system (CNS). The connection is multifaceted, involving the vagus nerve, the enteric nervous system (ENS), the immune system, and a vast number of microbial metabolites and neuroendocrine signals.

“Constipation is seen in 66 per cent of Parkinson’s patients, attributed to disordered central and peripheral parasympathetic disruption, and can lead to alteration of the gut microbiome, which in turn worsens constipation, starting a feedback loop,” the doctor explained.

What Parkinson’s Patients Must Eat

Dr Sudhir Kumar, Neurologist at Apollo Hospitals Hyderabad, told HealthandMe that changes in the gut microbiome may influence inflammation, α-synuclein aggregation, and symptom progression.

Practical dietary principles for Parkinson’s patients include:

• Prefer fiber-rich, plant-based foods (vegetables, fruits, whole grains), which support gut microbiota
• Include fermented foods (curd, buttermilk), which may improve microbial diversity
• Reduce ultra-processed and pro-inflammatory foods
• Ensure adequate hydration (helps reduce the risk of constipation, a common non-motor symptom)
• Protein timing matters: Levodopa competes with amino acids for absorption.

These gut-targeted interventions are promising adjuncts to conventional Parkinson's therapy, and improving patient quality of life.

Parkinson’s Treatment With Dance, Art

Beyond gut-brain axis, research has proven that unconventional therapy, like dance and art, can improve Parkinson’s treatment.

A 2024 study published in the Scientific Reports found that tango, particularly Argentine tango, improved Parkinson's symptoms like thinking problems or balance issues. It also led to a significant improvement in recognizing emotions on people's faces.

Dr Kumar said dance therapy improves balance, gait, and coordination; provides rhythmic cueing, which enhances motor performance, and improves mood and motivation (dopamine-related pathways).

Similarly, art therapy has been shown to improve overall visual-cognitive skills and visual exploration strategies as well as general motor function in patients with Parkinson’s. The changes in brain connectivity highlight a functional reorganization of visual networks, as revealed by a study published in Parkinsonism & Related Disorders.

Dr Kumar said art and creative therapies are also helpful in enhancing cognitive engagement. It may help with executive function and emotional well-being and provide a non-verbal outlet for expression. However, these therapies work best as adjuncts, not replacements, to standard treatment, the expert noted.

World Parkinson’s Day 2026

World Parkinson's Day is observed annually on April 11 to raise global awareness of Parkinson’s disease, the world's fastest-growing neurodegenerative disorder.

It highlights the need for early diagnosis, research, and support for the nearly 10 million people living with the condition. The day marks the birthday of Dr. James Parkinson, who first described the disease in 1817.

The theme of World Parkinson's Day 2026 is "Bridge the Care Gap." It reflects a critical challenge that persists despite advances in medical research: many people living with Parkinson's still lack consistent access to specialist care, affordable treatment, and integrated support systems.

Parkinson's disease affected 11.9 million people in 2021 and will affect 25.2 million people globally by 2050, representing an alarming 112 per cent rise.

For most working professionals, Parkinson’s disease still feels like something that happens much later in life. It’s not something people in their 30s or even early 40s actively think about. But this scenario is changed with early onset Parkinson’s disease (EOPD). This can affect people between the ages of 21 and 50.

The problem is not just the condition itself, but how it subtly integrates into everyday life. Despite this shift, early symptoms in working professionals often go unnoticed or are misattributed to stress, fatigue, or demanding work schedules.

What Is Early-Onset Parkinson’s Disease?

Parkinson’s disease is a neurological condition that affects movement and coordination due to a reduction in dopamine-producing cells in the brain. When it occurs between the ages of 21 and 50, it is referred to as early-onset Parkinson’s disease (EOPD). In younger individuals, the condition often develops slowly and remains mild in the beginning, which makes it harder to recognize. The exact cause may involve a mix of genetic factors and environmental triggers.

Symptoms can include both movement and non-movement changes. Movement-related symptoms may involve muscle stiffness, slowed movements, mild balance issues, tremors at rest, while non-movement symptoms such as constipation, unexplained pain, sexual dysfunction, and sleep disturbances like insomnia may appear early.

In day-to-day life, these changes often show up subtly as slight hand shaking at rest, taking longer to complete routine tasks, stiffness in the neck or shoulders, a softer or less expressive voice, and disturbed sleep patterns, signs that are easy to overlook or dismiss.

What are the symptoms that working professionals may miss?

1. Symptoms Overlap With Lifestyle Issues: In fast-paced work environments, fatigue, body aches, and sleep disturbances are common. Early Parkinson’s symptoms, such as stiffness, low energy, or poor sleep, are often dismissed as burnout or long working hours.

2. Lack of Awareness in Younger Age Groups: Both patients and even healthcare providers may not immediately suspect Parkinson’s in someone in their 30s or 40s. This leads to delays in seeking medical advice and diagnosis.

3. Absence of Classic Tremors Initially: Tremors are widely recognized as a hallmark of Parkinson’s, but they may not appear in the early stages. Instead, symptoms like reduced arm swing while walking or slight slowness in movements may be present but overlooked.

4. Attribution to Mental Health or Stress: Subtle changes such as anxiety, low mood, or difficulty concentrating can be early indicators. However, these are often attributed to workplace stress rather than a neurological cause.

5. Gradual Onset of Symptoms: Parkinson’s develops slowly. Changes in handwriting, posture, or speech may happen over time, making them difficult to notice unless specifically looked for.

How Can Parkinson’s Be Diagnosed and Managed?

Because early signs are often overlooked, the condition is often recognized only when it begins to affect daily life. Diagnosis typically involves a detailed assessment along with blood tests and imaging, such as MRI, and in some cases, specialized scans like a dopamine transporter (DAT) scan may also be advised to support the diagnosis.

Management focuses on improving quality of life through physical therapy to support movement and balance, occupational therapy to make daily activities easier, and speech therapy to address communication changes. In more severe cases, deep brain stimulation (DBS) surgery may be considered to help manage symptoms more effectively.

Parkinson’s at a younger age is often easy to overlook, especially when early signs blend into everyday stress and fatigue. Paying closer attention to overall well-being can help. Staying physically active, following a balanced diet, maintaining good sleep habits, and managing stress levels all play an important role in supporting brain health. Being mindful of small but persistent changes and not brushing them off as routine can go a long way in ensuring timely attention and better long-term.
