Smelling Smoke Before A Stroke: What's The Link?

There is a common misconception that smelling burning before a stroke is a typical sign of an impending stroke. However, while phantom smells, known as phantosmia, can be distressing and interfere with daily life, they are not indicative of an imminent stroke. Instead, phantosmia is often linked to sinus problems, certain medications, or other medical conditions. While strokes are serious and require immediate medical attention, the idea of smelling phantom burning before a stroke is more amusing than accurate.

Phantosmia, or olfactory hallucination, is a common type of phantom smell

Olfactory hallucinations can be caused by various medical conditions, such as nasal infections, nasal polyps, dental problems, migraines, head injuries, strokes, Parkinson's disease, seizures, or brain tumours. They can also be a symptom of certain mental disorders, including depression, bipolar disorder, intoxication, withdrawal from drugs and alcohol, or psychotic disorders. Environmental factors like smoking, exposure to certain chemicals, or radiation treatment for head or neck cancer can also trigger phantosmia.

The prevalence of phantosmia is relatively low, making up only 10-20% of cases of disorders affecting the sense of smell. It is often challenging to diagnose and treat phantosmia, as it may be caused by a variety of factors and can be a symptom of other illnesses. A physician can determine if the problem is related to the olfactory or gustatory system or if it is caused by a neurological or psychiatric disorder.

If you experience persistent phantom smells, it is recommended to consult a doctor to identify any underlying medical conditions. While phantosmia itself may not be a cause for concern, it could indicate a more serious health issue.

There is no evidence that phantom smells are a sign of a stroke

It is a common misconception that smelling burning before a stroke is a typical indicator of an oncoming stroke. However, there is no solid evidence to support this claim. While phantom smells, or olfactory hallucinations, can be distressing and disruptive to daily life, they are often not indicative of an oncoming stroke.

Phantom smells, or phantosmia, are relatively uncommon, making up around 10-20% of disorders related to the sense of smell. In most cases, phantosmia is not a cause for concern and will go away on its own. However, it can sometimes be a sign of a more serious underlying condition, so it is always recommended to consult a doctor.

There are various potential causes of phantom smells, ranging from issues with the nose or nasal cavity to problems with the brain's interpretation of smells. These include chronic sinus infections, allergic or non-allergic rhinitis, epilepsy, seizures, migraines, and Parkinson's disease. In some cases, phantosmia can also be a side effect of certain medications or exposure to toxins.

While smelling burnt toast specifically is not diagnostic, smelling something that isn't there can be a warning sign of a more severe condition. However, this is not necessarily indicative of a stroke. If you experience persistent phantom smells or notice specific signs of a serious condition, it is important to consult a doctor to rule out any potentially serious underlying causes.

Although smelling burning before a stroke is not a typical indicator, it is crucial to be aware of the warning signs of a stroke to enable quick action. A simple test, such as the "FAST" or "BEFAST" test, can help identify a stroke. These tests involve checking for face drooping, arm weakness, and speech difficulty. If any of these signs are present, it is crucial to seek immediate medical attention to improve the chances of a full recovery.

However, a stroke can sometimes affect an individual's sense of smell

While smelling burnt toast is not a typical sign of a stroke, phantom smells can be related to a number of conditions, and in some cases, even a stroke.

Phantom smells, or phantosmia, are a real phenomenon, but they are usually not the result of a brain blockage. However, a stroke can sometimes affect an individual's sense of smell. According to Dr. Salman Azhar, director of the stroke program at Lenox Hill Hospital in New York City, while the perception of smelling something burning does not automatically indicate a stroke, it's important to know that a stroke can sometimes "affect an individual's sense of smell".

Changes in smell may not be a primary red flag for stroke, but that doesn't mean there's no connection at all. "Stroke affects the brain and its functions, and of course, smell perception can be part of that," says Dr. Azhar. "It's not a classic sign, but it's also not impossible that it would be in the mix of stroke effects."

A study in BMC Neurology examined 78 participants who had experienced strokes and found that nearly a third of them had a reduced ability to smell, and 15% had lost their sense of smell in the year following their strokes. Older individuals tended to have higher levels of impairment, which may be related to age-related changes in smell, even without a stroke.

Shifts in smell can have a ripple effect on other areas of life, such as taste, nutrition, and mental health. According to a study in Topics in Stroke Rehabilitation, olfactory issues can impact taste, putting stroke survivors at risk for malnutrition and depression.

While phantom smells are not a typical indicator of a stroke, it's important to be aware of the warning signs of a stroke and seek immediate medical attention if you or someone around you experiences any symptoms.

Phantom smells can be caused by issues in the nose or brain

Phantom smells, or phantosmia, are indeed real. However, they are usually not the result of a brain blockage. Instead, they are often caused by issues in the nose or brain.

Phantom smells are a type of olfactory hallucination, where you smell something that isn't there. The most common type of phantom smell is that of burning or smoky odours, such as burnt toast. Other common phantom smells include metallic, chemical, spoiled or rotting, and stale or mouldy odours. These smells are usually unpleasant, though they can sometimes be pleasant.

Issues that begin in the nose, either in the olfactory nerves in the nose itself or in the olfactory bulb just above the nose, account for 52 to 72 percent of phantom smells. For example, chronic sinus infections, allergic rhinitis (hay fever), and non-allergic rhinitis can all cause phantosmia.

Phantom smells can also be caused by problems with how the brain understands smells. These issues can include epilepsy or seizures, migraines, Parkinson's disease, mental health disorders, and head injuries. When phantosmia is related to the brain or central nervous system, the phantom smells are often more persistent and noticeable during the day and night, and both nostrils experience the same smell.

While phantom smells are not usually a cause for concern and often go away on their own, they can sometimes be a sign of a more serious underlying condition. Therefore, it is recommended that anyone experiencing persistent phantom smells consult a doctor to rule out any serious conditions.

If you experience persistent phantom smells, see a doctor

Phantom smells, or phantosmia, are a real phenomenon, but they are usually not the result of a brain blockage. Phantosmia is a condition where a person smells something that isn't there. It is also called an olfactory hallucination. The phantom smells may be temporary or persistent, and they can be distressing and disruptive to daily life.

If you experience persistent phantom smells, it is important to see a doctor to rule out any serious underlying conditions. While phantosmia is often not a cause for concern, it can sometimes indicate a more severe condition, such as a brain tumour or a neurological issue.

To diagnose phantosmia, a doctor will first perform a physical examination, including a head and neck exam. They may also ask about your medical history, the onset and frequency of symptoms, and any potential triggers. In some cases, they may recommend specific tests to rule out possible causes, such as a nasal endoscopy, CT scan, MRI scan, or EEG scan.

Treatment for phantosmia will depend on the underlying cause. In some cases, the condition may resolve on its own over time. However, if a serious condition is identified, treatment options may include allergy medications, antibiotics, chemotherapy, surgery, or other cancer treatments.

It is important to note that smelling burnt toast or other phantom smells is not typically associated with having a stroke. While changes in smell may occur after a stroke, it is not considered a primary warning sign. However, if you experience any warning signs of a stroke, such as face drooping, arm weakness, or speech difficulties, seek immediate medical attention.
