Can anxiety cause olfactory hallucinations?
Conclusion. Olfactory hallucination can be the first and only symptom in patients with anxiety disorder and may be effectively treated with anti-anxiety medication. In fact, it can precede the diagnosis of anxiety disorder by several years.
Phantom Smells, such as odd, strong, acrid, metallic, blood-like, sour, ammonia-like, acidy, and repugnant smells, to name a few, are common anxiety disorder symptoms. Many anxious people report having phantom and odd smells as an anxiety symptom.
In fact, anxiety patients have shown deficits in odor discrimination and altered odor perception (38), suggesting that olfactory hallucination may be a symptom of anxiety disorder.
Phantosmia may be caused by a head injury or upper respiratory infection. It can also be caused by aging, trauma, temporal lobe seizures, inflamed sinuses, brain tumors, certain medications and Parkinson's disease. Phantosmia can also result from COVID-19 infection.
- rinsing your nasal passages with a saline solution (for example, with a neti pot)
- using oxymetazoline spray to reduce nasal congestion.
- using an anesthetic spray to numb your olfactory nerve cells.
Verbal hallucinations are often associated with pronounced feelings of anxiety, and it has also been suggested that anxiety somehow triggers them.
Moreover, it was demonstrated that stress affects smell recognition, including the development of olfactory system [44,45,46].
Clinicians may try using an anticonvulsant such as topiramate in such a case, especially when olfactory hallucinations are refractory to otherwise therapeutic doses of antipsychotics.
Smelling things that aren't there is called phantosmia. It can be unpleasant and affect how things taste. But it isn't usually serious and may go away by itself in a few weeks or months. See your GP if the strange smell doesn't go away in a few weeks.
One study on self-reported chemosensory alterations in a population-based US sample of adults 40 years and older found the prevalence of phantosmia to be 6% (Rawal et al.
Can depression cause olfactory hallucinations?
Olfactory hallucinations are considered important for the biological interpretation of affective disorders. In this regard disturbed olfactory perception can be understood as an example of disturbed brain function in the state of depression.
Phantosmia is not usually a cause for concern, and it often clears up by itself. It can also be a symptom of a more serious condition, so people experiencing phantom smells should see their doctor to check for underlying conditions or complications. The best treatment will depend on the cause of phantosmia.
If you got phantosmia after a viral infection like COVID-19 or a head injury, there's no treatment. But damaged nerves in your nose and nasal cavity do have the ability to grow back. It's possible for your sense of smell to partially or fully come back without treatment.
While auditory and visual hallucinations are known to represent common features of psychosis, tactile, olfactory, and gustatory hallucinations (TOGHs) are often believed to be rare in primary psychotic illness.
The term for this type of olfactory hallucination is dysosmia. Common causes of dysosmia are head and nose injury, viral damage to the smell system after a bad cold, chronic recurrent sinus infections and allergy, and nasal polyps and tumors. The brain is usually not the source.

If you're exposed to the same smell repeatedly, it can take even longer for your sensitivity to return. The best way to combat fragrance fatigue in that instance is to alternate between two or more fragrances that you like.
Coffee as an olfactory palate cleanser was actually first discovered by UC Berkeley neuroscientist Noam Sobel. He states that: Smelling coffee aroma between perfume samples, as compared to smelling unscented air, actually works.
Stress can exacerbate the symptoms of psychotic, mood, anxiety, and trauma disorders. And when these disorders are at a severe level is when the risk of psychosis is heightened. So, in a way, stress can indirectly cause hallucinations.
Causes of hallucinations
Intense negative emotions such as stress or grief can make people particularly vulnerable to hallucinations, as can conditions such as hearing or vision loss, and drugs or alcohol.
Can you be so stressed you hallucinate?
Causes of Hallucinations
Intense negative emotions such as stress or grief can make people particularly vulnerable to hallucinations. Conditions such as hearing or vision loss and drugs or alcohol can also cause hallucinations.
Anxious people have a heightened sense of smell when it comes to sniffing out a threat, according to a new study. Anxious people have a heightened sense of smell when it comes to sniffing out a threat, according to a new study by Elizabeth Krusemark and Wen Li from the University of Wisconsin-Madison in the US.
To the Editor: Previous reports described the presence of olfactory hallucinations in 10.3% of patients affected by post-traumatic stress disorder (PTSD),1 although there is limited understanding of this phenomenon.
Conclusions: Phantom odor perception may be a side effect of antidiabetic or antihyperlipidemic agents. Among people taking proton pump inhibitors, phantom odors may also be a consequence of gastric gas reflux.
Olfactory neuroblastoma, or esthesioneuroblastoma, is a tumor that grows in the nasal cavity. The nasal cavity has nerves and other tissue that are responsible for the sense of smell. This kind of tumor begins in the nasal cavity and can grow into the nearby eyes and brain.
Take sniffs of each scent for 10 to 20 seconds at least once or twice a day. While sniffing, it is important to be focused on the task. Try to concentrate on your memory of that smell. After each scent, take a few breaths and then move on to the next fragrance.
a brain tumour in the temporal lobe could lead to sensations of strange smells (as well as other symptoms, such as, difficulty with hearing, speaking and memory loss)
Medications: Antipsychotics, antimigraine medicine, and antiseizure drugs can all be used to treat phantosmia. Surgery: Olfactory mucosa excision surgery may relieve phantosmia while preserving olfactory function. Other: Transcranial stimulation and topical cocaine application have been used to treat phantosmia.
Phantosmia is when a person smells something that is not actually there. The smells vary between individuals but are usually unpleasant, such as burnt toast, metallic, or chemical smells. Possible causes range from nasal polyps to a stroke. Phantosmia is also called a phantom smell or an olfactory hallucination.
Olfactory reference syndrome (ORS), also known as olfactory reference disorder, is an underrecognized and often severe condition that has similarities to obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD). People with ORS think they smell bad, but in reality they don't.
Can anxiety trigger hallucinations?
Yes, stress is a common cause of hallucinations because of how stress affects the nervous system, sensory systems, and brain function. Since anxiety stresses the body, anxiety can also cause hallucinations. Many anxious and stressed people hallucinate, including auditory, visual, and olfactory hallucinations.
Hallucinations, usually fleeting and nocturnal, are typically visual and occur in 30% of treated patients. Auditory and olfactory hallucinations, however, are rare.
Phantosmia is not usually a cause for concern, and it often clears up by itself. It can also be a symptom of a more serious condition, so people experiencing phantom smells should see their doctor to check for underlying conditions or complications.

Olfactory hallucinations occur in epilepsy, especially in association with a temporal lobe focus, and commonly form the aura (or earliest phase) of such fits. A patient described a smell of burning rubber regularly just before he became unconscious.
Phantosmia and dysgeusia as the first presentation of glioblastoma.
