Phantosmia has been clinically related to schizophrenia and mood disorders: these mental diseases and perception of phantom smells have been linked to abnormal levels of several neurotransmitters such as acetylcholine, dopamine, and norepinephrine (27).
Is phantosmia a mental health condition? No, but phantosmia may be a symptom of some mood disorders and mental health conditions, including schizophrenia.
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, 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.
Other neurological and mental health conditions may cause phantom smells, including depression, migraine, brain injury, schizophrenia, and epileptic seizures.
Phantosmia is also called a phantom smell or an olfactory hallucination. Causes include problems with the nose, such as sinusitis, or conditions of the nervous system or brain, including migraine, stroke, or schizophrenia.
The two main symptoms of psychosis are: hallucinations – where a person hears, sees and, in some cases, feels, smells or tastes things that aren't there; a common hallucination is hearing voices.
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.
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.
Otolaryngologists play an important role in diagnosing phantosmia and treating many of its root causes.
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)
Although olfactory hallucinations are generally considered a hallmark of "organic" brain disease1,2 and are most commonly associated with temporal lobe epilepsy,3 the temporal sequence of Mr A experiencing the olfactory hallucination for 2 days but only while in his home make seizures unlikely.
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.
Two of the major events occurring after head injuries which are not commonly recognized but which significantly alter behavior are loss of smell acuity and subsequent onset of smell distortions or phantosmia.
Answer: Generally sinus disease or infection causes a foul odor and not the smell of cigarettes. Often odors can linger on clothing, carpet, furniture, automobile seats, drapery etc. Some brain tumors can cause olfactory (smell) delusions or hallucinations and these can be manifest as almost any odor.

We describe a patient who presented with a history of phantosmia. This patient was investigated for a nasal infection, with a nasal culture growing the bacteria Pseudomonas stutzeri. This patient's phantosmia was cured by treating the nasal infection.
It is usually reported in 65–90% of PD patients [7,8], may often precede the onset of motor symptoms, and may manifest as hyposmia/anosmia, parosmia (distorted perception of an odor), and phantosmia (perception of an odor in the absence of a relevant odor source), also indicated as olfactory hallucinations (OHs) [9,10] ...
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.
The prevalence has been estimated to range between 0.8% and 25% depending on the clinical group studied (Nordin et al. 1996; Landis et al. 2004), yet little is known about the prevalence of phantosmia in healthy individuals.
The typical course of a psychotic episode can be thought of as having three phases: Prodrome Phase, Acute Phase, and Recovery Phase.
It has long been known that people suffering schizophrenia and other forms of psychosis are often unable to correctly identify smells. That is, pizza may be mislabelled as orange, or bubblegum as smoke.
