New research shows how anxiety or stress can rewire the brain, linking centers of emotion and olfactory processing, to make typically benign smells malodorous. In evolutionary terms, smell is among the oldest of the senses.
Phantosmia, which is an olfactory hallucination, sometimes occurs with anxiety. It can cause you to smell something that isn't there, or rather, a neutral smell becomes unpleasant. Most often, this bizarre sensation is caused by antidepressants or withdrawal from them. However, sometimes it's associated with anxiety.
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.
Phantosmia is a condition that causes you to detect smells that aren't actually in your environment. It can happen in one nostril or both — and the odors may be foul or pleasant. Common causes include colds, allergies, nasal polyps and dental issues.
Anxiety can cause a wide variety of symptoms, including phantom smells (phantosmia or olfactory hallucinations). Many people with anxiety report smelling odd smells that other people do not smell.
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.
Research also suggests that chronic psychological distress may lead to functional changes in the olfactory system that cause heightened sensitivity to odors.
Parosmia is a condition where a person's sense of smell no longer works correctly. Caused by infections like COVID-19, head injuries, or other neurological conditions, this loss of smell can be an inconvenience for some— and a significant problem for the quality of life of others.

Phantosmia and dysgeusia as the first presentation of glioblastoma.
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.
Health anxiety can actually have its own symptoms because it's possible for the person to have stomachaches, dizziness, or pain as a result of their overwhelming anxiety.
Sensory overload and anxiety are mental health conditions that are deeply related to one another. When a person feels anxious or already overwhelmed, they may be more prone to experiencing sensory overload in certain situations. Likewise, experiencing sensory overload can make you feel a sense of anxiety.
Your olfactory nerve is the first cranial nerve (CN I). It's also part of your autonomic nervous system, which regulates body functions. This nerve enables your sense of smell. Cranial nerve 1 is the shortest sensory nerve in your body.
Changes in sense of smell are most often caused by: a cold or flu. sinusitis (sinus infection) an allergy, like hay fever.
Parosmia is a distorted sense of smell. It happens when smell receptor cells in your nose don't detect odors or transmit them to your brain. Causes include bacterial or viral infections, head trauma, neurological conditions and COVID-19. Parosmia is usually temporary, but in some cases, it's permanent.
Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. It's also called "fish odour syndrome". Sometimes it's caused by faulty genes that a person inherits from their parents, but this isn't always the case.
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)
A study that evaluated the ortho- and retronasal olfactory functions in MS patients found that 75% of the 16 investigated patients showed a quantitative olfactory disorder, 6.25% reported parosmia, and 18.75% reported phantosmia (29).
This is called phantosmia, from the Greek words phantasm (meaning illusion) and osme (meaning smell). It's an exceptionally rare condition in neurology. My doctors say that this can occur in relation to brain injuries, strokes, seizures, schizophrenia, Parkinson's disease and other neurological disorders.
having a sense of dread, or fearing the worst. feeling like the world is speeding up or slowing down. feeling like other people can see you're anxious and are looking at you. feeling like you can't stop worrying, or that bad things will happen if you stop worrying.
