Benfotiamine or vitamin B1 helps the olfactory nerve already weakened by excessive alcohol consumption, too much sugar, diabetes, and others ailments. Choose a liposoluble benfotiamine (#ad) so that the vitamin more easily penetrates the nerves and begins to repair them. The recommended dose is 100mg a day.
What will happen if olfactory nerve is damaged?
The olfactory neurons regenerate and can grow new nerve fibres, or axons, which can attach themselves to the olfactory bulb, thus restoring the connection between the receptor cells and the bulb. However, damage sustained in the injury can lead to the development of scar tissue which can prevent the axons reaching the bulb.
How to heal olfactory nerves?
- Try to avoid offensive or toxic odors because prolonged exposure to those smells can cause damage this system. ...
- Going on a walk in an area with no pollution is a great way to enhance your olfactory system.
- Eat foods with zinc or take zinc supplements because zinc deficiency decreases the sense of smell.
Is it possible to regenerate nerve damage?
Regeneration of the peripheral nerve is possible and all events of regeneration occur around the axon when the nerve is cut. The proximal stump will regenerate and the distal stump will have Wallerian degeneration. Macrophagocytes dispose of the degenerated axon and myelin sheath.
Are damaged olfactory neurons replaced?
This vulnerability to the damage from the external environments is probably why ORNs, unlike most other neurons, have the ability to regenerate from a precursor population. ORNs turn over every 30 days on average; they are replaced from a stem cell population of basal cells.
Can olfactory nerves regenerate?
Unlike nerve cells anywhere else in the body, the olfactory neurons are able to recover or regenerate after injury. This means that incidences of anosmia can be temporary.
How long does it take for olfactory nerve to regenerate?
Research has shown that each regenerating olfactory axon can follow the pathway created by pre-existing axons every 30–90 days.
How do you stimulate the olfactory nerves?
Carry a vial of a nonirritating substance in your bag; vanilla, lemon, and freshly ground coffee are good examples, and tobacco or scented soap will do if necessary. These odors stimulate the olfactory receptors. Do not use irritating odors such as camphor or menthol.
What vitamins help regenerate olfactory nerves?
Vitamin A plays a decisive role in the regeneration of olfactory receptor neurons. In this retrospective study we investigated the effectiveness of topical vitamin A in patients with post-infectious and posttraumatic smell disorders.
How do you repair olfactory nerve after Covid?
Training the nose The mainstay of treatment for post-COVID smell loss is olfactory training — a procedure that many rhinologists compare to physical therapy for the nose.
Is loss of smell permanent?
In most cases, the smell loss lasts only a few weeks, but for more than 12 percent of people with COVID-19, olfactory dysfunction persists in the form of ongoing reduction in the ability to smell (hyposmia) or changes in how a person perceives the same smell (parosmia).
Can loss of taste and smell be restored?
Traditional therapy to treat this condition can require a painful injection directly up the nostril to the olfactory nerve. But, Dr. Rosen began trying a less invasive treatment using a topical application of platelet-rich plasma (PRP) into the nose to stimulate cell regrowth and restore taste and smell.
How do you treat no sense of smell?
Treatments that may help resolve anosmia caused by nasal irritation include:decongestants.antihistamines.steroid nasal sprays.antibiotics, for bacterial infections.reducing exposure to nasal irritants and allergens.cessation of smoking.
How do you retrain your sense of smell and taste after Covid?
While its effectiveness may vary from person to person, there isn't any harm in trying. Smell training after COVID involves picking four scents or fragrances and smelling them twice a day for several months. You can switch out the scents after several weeks and try new ones.

When will I get my taste and smell back?
Dr. Piccirillo says most of those who suffer the loss of smell, loss of taste or both during COVID-19 infection quickly regain it. But, for those whose sense of smell hasn't returned after six months or longer — generally 5% to 10% of those who initially suffered the loss — Dr.
What medicine improves sense of smell?
Nasal decongestants can open up your nasal passages and make you breathe easier as well as improve your sense of smell. They are available in the form of sprays, drops, and inhalers. Antihistamine: Antihistamines can relieve nasal congestion, stuffy nose, and other allergy symptoms.
What happens when the olfactory nerve is damaged?
A damaged sense of olfaction is severely disrupting: the joy of eating and drinking may be lost, and depression may result. Furthermore, there are dangers associated with the loss of smell, including the inability to detect leaking gas or spoiled food.
Can you recover from Parosmia?
Although high rates of spontaneous recovery have been reported for non-covid related parosmia, the timeline varies widely from months to sometimes years. 6 A survey of 434 patients with self reported olfactory loss after covid-19 found that 43.1% reported parosmia at six months.
What causes olfactory nerve damage?
The principal causes of olfactory dysfunction are sinonasal diseases, viral infections, head injuries, and neurodegenerative diseases.
What is the function of the olfactory nerve?
Function of the Olfactory Nerve. The olfactory nerve is responsible for your sense of smell and partially responsible for your sense of taste. It is also known as cranial nerve 1 because it is the shortest of the cranial nerves and one of only two nerves (the other is the optic nerve) that bypass the brain stem and connect directly to your brain.
Where does the olfactory nerve begin?
The olfactory nerve begins in the region of the nasal cavity known as the olfactory epi thelium. The epithelial cells there are covered with tiny hairs called cilia on one side, and they are connected to an axon, which is the main body of a nerve cell, on the other side.
What happens when the cribriform plate is broken?
This often happens when the cribriform plate is broken, severing the axons of the olfactory nerve. Even if the cribriform plate is not broken, a blow to the head or face can damage these delicate cells and result in a partial or total loss of smell.
What are the disorders of the olfactory system?
Disorders of the olfactory system include anosmia (an inability to smell), hyposmia (a reduced ability to smell), and dysosmia (a distortion of your perception of a smell). To unlock this lesson you must be a Study.com Member. Create your account.
Which nerve is responsible for the sense of smell?
Lesson Summary. To review, the olfactory nerve is responsible for your sense of smell. It does this by detecting chemicals floating around in the air and transmitting information about them to your brain, where you interpret the signal as a certain smell.
Can you smell without a olfactory nerve?
Without a properly functioning olfactory nerve, you wouldn't be able to smell any of these things. Your olfactory nerve is also very important in giving you a sense of taste, so if it is not functioning, then you wouldn't be able to taste much either! {"error":true,"iframe":true}.
Is anosmia a degenerative disease?
Anosmia can also be a symptom of several degenerative brain diseases, like Parkinson's disease and Huntington's disease. In these diseases, neurons throughout the brain are affected, but the olfactory nerve is often one of the earliest nerves to develop noticeable dysfunction.
What is the function of the olfactory nerve?
Associated Conditions. Treatment. Actually a pair of cranial nerves, the olfactory nerve transmits information to the brain from smell receptors in the nose. The olfactory nerve is sometimes referred to as the first cranial nerve, or CN1. Cranial means "of the skull.".
Where is the olfactory nerve located?
That might seem odd since the olfactory nerves are in the front of the brain. When there's an impact on the back of the head, the brain can come forward and collide with the inside front of the skull—right where the olfactory nerve is.
What nerve is responsible for smell?
Unlike many other nerves, the olfactory nerve has one job—making you able to smell things. When particles in the air enter your nasal cavity, they interact with the receptors on the olfactory nerve and a type of tissue called the olfactory epithelium, which is in several areas of the nasal cavity and contains millions of receptors.
Why does my sense of smell decrease?
A decreased sense of smell can also occur due to tumors, such as meningiomas of the olfactory groove as well as be an early feature of some neurological diseases such as Parkinson's disease, Alzheimer's disease, and Lewy body dementia.
What is the term for a disordered smell?
This is called an olfactory hallucination.
What causes a loss of smell?
Anosmia: Anosmia is the total loss of the sense of smell. It can be caused by infection, blockage, or head injury. Hyposmia: Hyposmia is a reduced ability to detect odors. It can be caused by allergies, nasal polyps, viral infections, and head trauma.
Where does the nasal nerve originate?
It originates in the olfactory mucosa (mucous membrane) along the roof of your nasal cavity (nostril). This nerve is made of many small nerve fibers called fascicles that are bound together by thin strips of connective tissue. The bundle extends from the nasal cavity through the ethmoid bone behind your nose.

Olfactory Nerve Regeneration Time Period After The Damage
Abstract
Introduction
Discussion/Conclusion
- If you've lost your sense of smell to a known cause that's treatable—such as by surgically removing nasal polyps, straightening the septum, or clearing out the sinuses—it's possible that your sense of smell will improve over time. That's what happens in many cases of post-viral olfactory loss, although the sense may never be fully restored. A study...
