An unusual medical condition has caught the attention of doctors and the public. Argyria, a rare disorder caused by the accumulation of silver in the body, has left people with a permanent gray or blue-gray skin tone. Though such a transformation might seem like a scene from a science fiction movie, it is very real—and the effects are long-lasting.

In this article, we shall look at the causes, symptoms, diagnosis, and treatment of argyria. We shall also address its risks, preventive measures, and new research on the condition.

Argyria is a condition resulting from the long-term accumulation of silver in the human body, leading to the permanent discoloration of skin, eyes, and other tissues especially when exposed to sunlight. This condition results primarily from the overexposure to silver particles due to occupation or ingestion of compounds containing silver.

A case that gained much attention was that of an 84-year-old man in Hong Kong, whose ashen color complexion resulted from his exposure to silver. This man had initially been admitted to the hospital upon noticing a change in his skin color. Through further analysis, silver granules were identified within his skin tissues, blood vessels, and sweat glands. His blood tests revealed that his serum silver concentration was 40 times higher than normal, and he was diagnosed with argyria. Although he claimed to have no direct exposure to silver, the case revealed the hidden dangers of silver accumulation in the body.

How Does Silver Accumulate in the Body?

Most frequently, argyria is caused due to the ingestion and inhalation of silver or a compound containing the metal. As the silver particulates enter through the bloodstream in such cases, silver deposits in nearly all tissues- skin, liver, kidneys, lungs, spleen, or even the brain.

The commonest symptom presenting in argyria is, of course when silver accumulates in the skin. Light-exposure to silver triggers a form of photoreduction with the ultraviolet components of sunlight to take on a tinge of bluish or even grayish skin. This has also been implicated in other sites, including those in the fingernails and gums, plus the eyes of some patients who develop this. Internal organs sometimes take on blueish tinges, such as the liver or spleen but only through X-rays or another medical imaging modalities.

Who Is Likely to Get Argyria?

Argyria is currently an infrequent disease, though historically, the prevalence was more pronounced. This is mainly because during the 19th century, most people had intensive exposure to silver. Some common uses of silver during the same period were its application in various industries like mining and processing and as medication. The present leading causes of argyria include:

Ingestion of Colloidal Silver

Colloidal silver is a liquid solution that has tiny particles of silver, which is mostly sold as a dietary supplement. Those who ingest colloidal silver for purported health benefits—used allegedly to boost the immune system to treat everything from diabetes and cancer—risk argyria. The use of colloidal silver has not been supported by scientific research; experts in health also warn consumers from using such.

Work Exposure

People working in silver-related industries like silver mining, manufacturing, or jewelry making. If the workers have an extended exposure to silver particles suspended in the air or deposited on the skin.

Prolonged use of medication that contains silver compounds as a component. An example of such medication is eyedrops or nasal sprays. Silver accumulation in the body may occur with a prolonged duration of medication use.

Genetic predisposition

Some rare genetic factors may predispose a few people to the condition.

Symptoms of Argyria

The main symptom of argyria is the gradual appearance of bluish-gray or grayish discoloration of the skin, mainly in areas exposed to sunlight. The color change is permanent and may cause psychological distress in most patients. Other symptoms of argyria include:

• As silver builds up in the body, fingernails may darken.
• Dark spots may appear on the skin, especially in skin areas that receive regular exposure to sunlight.
• The whites of the eyes (sclera) turn a bluish-gray color.
• In some cases, argyria patients may report mild symptoms including stomach discomfort, fatigue, or headaches.
• Over time, internal organ damage such as the liver, spleen, and kidneys may occur due to silver buildup; however, these symptoms are not always observable.

The condition is not fatal, but the symptoms may be uncomfortable, and the discoloration is permanent.

How is Argyria Diagnosed?

Argyria is usually established by a case history, medical examination, and laboratory tests. A crucial diagnostic method is to undertake a biopsy on the affected areas of the skin, which, in turn can show silver particles in the tissue. Blood examination can also tell the concentration level of silver inside the blood of the patient after the diagnosis. After establishing this diagnosis, another step is toward the cause or reason behind deposition of silver.

Treatment and Management

Currently, there is no treatment for argyria. The coloration due to the condition is irreversible. However, there are several measures to help manage the appearance of the condition:

• Regular application of sunscreen can prevent the coloration from worsening since exposure to UV rays accelerates the photoreduction process.
• Though not universally successful, some patients have undergone laser therapy to minimize the appearance of the coloration, though success varies.
• Many individuals use makeup to cover the grayish tint of their skin and restore a more natural appearance.
• Some topical treatments, such as 5% hydroquinone, may help lighten the skin and reduce the appearance of the discoloration.

In addition to cosmetic treatments, it is essential for individuals to avoid further exposure to silver or silver-containing compounds to prevent the condition from worsening.

Is Argyria Preventable?

Preventing argyria is largely about avoiding unnecessary exposure to silver. If you are taking dietary supplements or medications that contain silver, consult with your healthcare provider to explore alternative options. People who work with silver should ensure that their workplace adheres to safety regulations, such as the Occupational Safety and Health Administration’s (OSHA) exposure limits for silver dust.

Argyria is a rare but serious condition that can have a significant impact on an individual’s appearance and well-being. Although modern exposure to silver is less common than in previous centuries, certain lifestyle choices, such as using colloidal silver as a supplement or working in silver industries, still pose a risk. Understanding the causes, symptoms, and prevention of argyria is key to minimizing its impact on health. Although it has no known cure, precautions and proper remedies can be availed to lessen the impact brought about by the condition.

Parkinson's disease is a progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells, primarily affecting people over 60. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety and swallowing problems.

The first symptom may be a barely noticeable tremor in just one hand or sometimes a foot or the jaw. Over time, swinging your arms may become difficult and your speech may become soft or slurred. The disorder also causes stiffness, slowing of movement and trouble with balance that raises the risk of falls.

However, before clear symptoms begin to appear, Neurologist Rachel Dolhun says certain signs may help identify the onset of the disease decades before it is diagnosed.

“It’s important to stress that not everyone who has these symptoms goes on to develop Parkinson’s,” said neurologist Rachel Dolhun. “But we know that in some people, these can be some of the earliest signs," she told The Washington Post.

Here is what you should look out for:

1. Loss Of Smell

Loss of smell, or hyposmia, is a common and early non-motor symptom of Parkinson's disease, affecting up to 90 percent of patients. This symptom can significantly impact quality of life by reducing the enjoyment of food and diminishing appetite.

While strongly linked to Parkinson's, smell loss can also stem from other causes, including sinus problems, COVID-19, or aging.

2. Acting Out Dreams

Acting out dreams, known as REM Sleep Behavior Disorder (RBD), involves physically enacting vivid, often unpleasant dreams through shouting, punching, or kicking during sleep.

This typically happens because the brainstem fails to temporarily paralyze muscles during REM sleep. It is a strong early warning sign of Parkinson's disease, often appearing years or decades before motor symptoms. About 50 percent of people with Parkinson's experience RBD.

3. Constipation

Constipation is a very common and significant non-motor symptom of Parkinson's disease that is caused by nerve changes slowing gut muscles and potentially exacerbated by low activity and dehydration.

Constipation can also be caused by Parkinson's medications such as anticholinergics, amantadine and other common drugs such as opioids, iron/calcium antacids.

4. Dizziness As You Stand

The autonomic nervous system fails to properly constrict blood vessels or increase heart rate upon standing, often due to a lack of norepinephrine. This causes the autonomic nervous system to fail in regulating blood pressure. Over time, this leads to Neurogenic Orthostatic Hypotension.

Beyond dizziness, symptoms include blurred vision, weakness, fatigue, cognitive "fog," and "coat hanger pain" (pain in the neck/shoulders). Often times, patients experience dizziness in the morning or immediately after meals.

Diagnosing Parkinson’s disease is mostly a clinical process, meaning it relies heavily on a healthcare provider examining your symptoms, asking questions and reviewing your medical history. Various imaging and diagnostic tests used to detect disease includes CT scan, PET scan, MRI scan and genetic testing.

Beyond icy roads and fogged-up car windscreens, the coldest season can also bring on a painful condition that leaves the skin covered in red, itchy patches. Doctors have issued a warning about this lesser-known illness, which tends to worsen in low temperatures.

The condition, known as cold urticaria, affects around one in 2,000 people. It causes swelling and itching of the skin when it comes into contact with cold air, cold water, or even air conditioning. Red welts or hives can appear within minutes, and the discomfort may last for as long as two hours.

What Is Cold Urticaria?

Cold urticaria is an uncommon condition in which the body reacts abnormally to cold temperatures. It typically causes rashes or hives after exposure to cold air, water, food, or drinks. In some cases, symptoms can be more serious. According to the Cleveland Clinic, the condition may sometimes be linked to an underlying blood cancer or an infectious illness.

Griet Voet, head of a dermatology clinic in Ghent, Belgium, as per Express UK, said the condition is often confused with common winter skin problems such as eczema. “This is not just dry skin caused by cold weather, it is a genuine allergic reaction to cold,” she explained. In more severe cases, large areas of the body may be affected, particularly after swimming in cold water or spending extended periods outdoors. This can lead to intense itching, facial flushing, and even headaches, stomach pain, or fainting. Sudden temperature shifts, such as moving from a warm indoor space into cold outdoor air, can also trigger symptoms. Drinking ice-cold beverages may cause swelling of the lips, mouth, or throat.

Cold Urticaria: What Are The Symptoms Of This Disease?

Symptoms of cold urticaria differ from person to person and can range from mild to severe. They may be limited to a small patch of skin or spread across the entire body.

The most common sign is a skin rash that appears after contact with something cold. The rash usually develops once the exposure ends, as the skin begins to warm up.

The rash may include:

• Hives, bumps, or raised welts
• Itching
• Redness
• Swelling

• Fatigue
• Fever
• Headache
• Joint pain

• Fainting
• Heart palpitations
• A severe allergic reaction known as anaphylaxis
• Shortness of breath or wheezing

How Is Cold Urticaria Diagnosed?

A medical professional can often diagnose cold urticaria using a simple test. An ice cube is placed on the skin, usually on the arm, for a few minutes and then removed. If a hive or rash appears several minutes later, the result is considered positive.

In cases of familial cold urticaria, diagnosis may involve exposure to cold air for a longer duration.

Doctors may also suggest blood tests to check for any underlying illness or infection that could be contributing to the condition.

Health authorities have urged the public to stay alert to Nipah virus symptoms after doctors warned that up to 75 per cent of infected patients may not survive. The UK Health Security Agency (UKHSA) has classified Nipah as a “high priority pathogen” because of its severe fatality rate and the absence of any proven treatment.

In India, the federal health ministry has confirmed two cases in the eastern state of West Bengal. This has triggered large-scale containment measures, with local officials placing nearly 200 people who had contact with the infected individuals under quarantine.

In response, several Asian nations have stepped up airport checks and health surveillance for travellers arriving from India. Professor Paul Hunter, an infectious disease specialist at the University of East Anglia, said identifying Nipah cases at borders is challenging, as symptoms can take a long time to appear.

What Is Nipah Virus?

According to UKHSA, Nipah virus is a zoonotic infection, meaning it can pass from animals to humans. It can also spread through contaminated food or via direct human-to-human contact. The virus was first discovered in 1999 during an outbreak affecting pig farmers in Malaysia and Singapore.

Fruit bats, especially those belonging to the Pteropus species, are the virus’s natural carriers. Research shows that Nipah can also infect other animals, such as pigs, dogs, cats, goats, horses and sheep.

Nipah Virus Symptoms

• Sudden onset of fever or general flu-like illness
• Development of pneumonia and other breathing-related problems
• Swelling or inflammation of the brain (encephalitis) or meningitis

Symptoms usually appear between four and 21 days after exposure, although longer incubation periods have occasionally been reported. More severe complications, including encephalitis or meningitis, can develop between three and 21 days after the initial illness begins.

UKHSA has cautioned that between 40 and 75 per cent of people infected with Nipah virus may die. Those who survive can experience long-term neurological effects, such as ongoing seizures or changes in behaviour and personality. In rare instances, the virus has been known to reactivate months or even years after the first infection.

Nipah Virus: Can You Prevent It From Spreading?

For people travelling to regions where Nipah is known to occur, prevention largely involves reducing exposure risks:

• avoid contact with bats, their habitats, and sick animals
• do not drink raw or partially fermented date palm sap; if consuming date palm juice, make sure it has been boiled
• wash all fruits well with clean water and peel them before eating; avoid fruits found on the ground or those that appear partly eaten by animals
• use protective clothing and gloves when handling sick animals or during slaughter and culling
• maintain good hand hygiene, especially after caring for or visiting ill individuals
• avoid close, unprotected contact with anyone infected with Nipah virus, including exposure to their blood or bodily fluids

Nipah Virus Symptoms Can Be Transmitted Easily?

Many Nipah infections have been linked to eating fruit or fruit-based products contaminated by the saliva, urine or droppings of infected fruit bats. Human-to-human transmission can also occur through close contact with an infected person or their bodily fluids, according to Mirror.

Such transmission has been documented in India and Bangladesh, with cases often involving family members or caregivers tending to infected patients. At present, there is no specific, proven treatment for Nipah virus infection, and no licensed vaccine is available to prevent it.

So far, no Nipah virus cases have been reported in the United States or the United Kingdom.
