When taking a history of the possible causes of anosmia, it is important a clinician keep?
When taking a history of the possible causes of anosmia, it is important a clinician keep the possible etiologies (listed above) in mind when asking relevant questions.
What causes anosmia?
There are many causes. Neurological causes can include disturbances to the sensory nerves that make up the olfactory bulb or anywhere along the path in which the signal of smell is transferred to the brain. From the olfactory bulb, the signal is further processed by several other structures of the brain, including the piriform cortex, entorhinal cortex, amygdala, and hippocampus. Any blockage or destruction of the pathway along which smell is transferred and processed may result in anosmia. This activity describes the evaluation, diagnosis, and management of anosmia and highlights the role of team-based interprofessional care for affected patients.
Why can't I smell?
It can be temporary or permanent and acquired or congenital. There are many causes. For example, any mechanical blockage preventing odors from reaching the olfactory nerves can cause a loss of sense of smell. This blockage can be due to inflammatory processes like simple infections causing mucus plugs or nasal polyps. Neurological causes can include disturbances to the sensory nerves that make up the olfactory bulb or anywhere along the path in which the signal of smell is transferred to the brain. To better understand this process, it is helpful to understand how people can perceive smell. When a particle with odorant molecules in the air is present, it travels up through the nasal canals to the nasal cavity, where olfactory receptor neurons extend from the olfactory bulb that sits on the cribriform plate of the brain. Each nasal cavity contains about 5 million receptor cells or neurons. There are 500 to 1000 different odor-binding proteins on the surface of these olfactory receptor cells. Each olfactory receptor cell expresses only one type of binding protein. These afferent olfactory neurons (cranial nerve I) facilitates the transfer of a chemical signal (particles in the air) to an electrical signal (sensed by afferent receptor neurons) which is then transferred and ultimately perceived by the brain. From the olfactory bulb, the signal is further processed by several other structures of the brain, including the piriform cortex, entorhinal cortex, amygdala, and hippocampus. Any blockage or destruction of the pathway along which smell is transferred and processed may result in anosmia.[1][2][3][4]
How many people have anosmia?
In the United States, anosmia afflicts 3% of the adult population older than the age of 40. The prevalence of impaired olfaction increases with age. In 2016, the National Health and Nutrition Examination Survey (NHANES) measured olfactory dysfunction which involved 1818 participants. Data showed that olfactory dysfunction was 4% at age 40 to 49 years of age, 10% at 50 to 59, 13% at 60 to 69, 25% at 70 to 79, and 39% for those over 80 years of age.

Can olfactory neurons regenerate?
For olfactory impairment caused by damage to the olfactory neurons due to trauma, there is no specific treatment. However, olfactory neurons do have the ability to regenerate. But the time and degree of regeneration depend on the extent of damage, and there is a difference in regenerative abilities between individuals. Regeneration can span over the course of days to years, and complete recovery is not a guarantee.

Is there a treatment for anosmia?
Some medications/treatments that have been reported to help have significant adverse side-effects and, importantly, NONE have been approved specifically for the treatment of anosmia/hyposmia, although some have been approved for treatment of underlying problems , such as the use of steroid sprays for chronic nasal inflammation. You should always ask whether any suggested treatment has been tested in properly controlled, clinical trials whose results have been published in peer-reviewed professional journals. The placebo effect is powerful, and careful double-blind studies (where neither the MD nor the patient know whether they are getting the drug or the placebo or control) are required to insure that an apparently effective treatment is truly effective. Anything that doesn’t meet those criteria must be viewed as experimental and should be tried only if you fully recognize the risks involved and are willing to be a ‘guinea pig’! Unfortunately, there are practitioners out there that are more interested in their own gain than in your health, or are well-meaning, but simply misinformed – be an alert consumer.

Can a head injury cause smell loss?
In some circumstances, your evaluation may uncover a head injury that preceded your smell loss. In such injuries the connections between the smell receptors in the nose and the smell centers in the brain are severed. Recovery from such losses is delayed and gradual and occurs only in about 1/3 of such cases.
Can loss of smell be reversed?
Can losses in the sense of smell be reversed through other means? According to the US National Institutes of Health, there currently are no evidence-based preventive measures, interventions, or treatments available for anosmia. However, there now are a number of lines of evidence suggesting that regular, intermittent exposure to odors, with efforts to identify smells, can lead to improvements in olfaction. Just as athletic injuries and stroke-induced disabilities can be improved through early rehabilitation, smell loss can be helped through olfactory retraining.
Where does the term "anosmia" come from?
The term derives from the New Latin anosmia, based on Ancient Greek ἀν- (an-) + ὀσμή ( osmḗ, "smell"; another related term, hyperosmia, refers to an increased ability to smell). Some people may be anosmic for one particular odor, a condition known as "specific anosmia". The absence of the sense of smell from birth is known as congenital anosmia.

The lack of the sense of smell at birth, usually due to genetic factors, is referred to as congenital anosmia. Family members of the patient suffering from congenital anosmia are often found with similar histories; this suggests that the anosmia may follow an autosomal dominant pattern.
Why is losing smell dangerous?
Loss of smell can also be dangerous because it hinders the detection of gas leaks, fire, and spoiled food. The common view of anosmia as trivial can make it more difficult for a patient to receive the same types of medical aid as someone who has lost other senses, such as hearing or sight.

What is the initial or essential anosmia?
Thus, the initial or essential anosmia is determined by destructive changes in the olfactory epithelium, when receptors cease to detect odors, that is , react to particles of volatile substances that enter the nasal cavity with air. This form of loss of smell is considered peripheral and as a symptom occurs with infections, in particular, as a loss of smell in the common cold.
What is neurotransmitter and central anosmia?
The ability to sense odors can be lost due to a violation of the transmission of signals from olfactory sensory neurons to the brain (sensory transduction) or damage and dysfunction of the main brain structures that analyze nerve impulses and generate a response-a limbic system-sensed smell. In the first case, it is a neurotransmitter (conductor) anosmia, and in the second case - about the central (cerebral) or sensorineural.
How to get rid of olfaction in the nasal cavity?
But the use of intranasal means does not guarantee the restoration of olfaction, moreover, the mechanism of their pharmacological action and does not take into account the damage to the olfactory epithelium of the nasal cavity. Similarly, inhalations with loss of smell are aimed at eliminating the obstruction of nasal passages, and they certainly bring relief in the common cold. The most effective will be herbal treatment: hot steam inhalation with the addition of chamomile or lavender flowers, plantain leaves, eucalyptus or sage and thyme grass - five minutes a day, three to four times a week or every other day. Physiotherapeutic treatment is also possible - see Physiotherapy with rhinitis
