How to differentiate between patient with olfactory nerve problem or with malinger?


How can a doctor know that the patient is malingering or if he/she truly have an olfactory nerve problem?
----------

I'm not a doctor yet, but I would suggest testing them with some really noxious odor that they would not be able to pretend they don't smell. Or have them come into a room, and have the room flooded with said noxious odor when they are by themselves, but record them or secretly observe them to see if they react since no one is around. Some people vomit just from the smell of vomit, feces, dead fish, etc. If they don't see it, how else would they be able to react without smelling it? Good luck!

Can they taste food? Ask them what foods they have been eating lately, but try to disguise what you're looking for - people who cannot smell cannot taste much, either.  (+ info)

What does damage to the olfactory system lead to?


I heard that above the nasal cavity, there is the olfactory which helps perceive smells, but what about tastes? I heard if you damage this area, it can make food all taste the same but I'm not sure if that's true or not.
----------

The olfactory nerve, or cranial nerve I, is the first of twelve cranial nerves. The specialized olfactory receptor neurons of the olfactory nerve are located in the olfactory mucosa of the upper parts of the nasal cavity. The olfactory nerves do not form two trunks like the remaining cranial nerves, but consist of a collection of many sensory nerve fibers that extend from the olfactory epithelium to the olfactory bulb, passing through the many openings of the Cribriform plate of the Ethmoid bone; a sieve-like structure.

Olfactory receptor neurons continue to be born throughout life and extend new axons to the olfactory bulb. Olfactory ensheathing glia wrap bundles of these axons and are thought to facilitate their passage into the central nervous system.

The sense of smell (olfaction) arises from the stimulation of the olfactory receptors by activation from small molecules of different spatial, chemical, and electrical properties that pass over the nasal epithelium in the nasal cavity during inhalation. These interactions are transduced into electrical activity in the olfactory bulb which then transmits the electrical activity to other parts of the olfactory system and the rest of the central nervous system via the olfactory tract.

The olfactory nerve is the shortest of all the twelve cranial nerves and only one of two cranial nerves (the other being the optic nerve) that do not join with the brainstem.

I hope I have answered your question.

What occupations help people with hearing, seeing, sensory, and olfactory issues?


I'm looking for an occupation that helps people who have problems with their sensory abilities like seeing, hearing, tasting, smelling, and feeling. What professions or occupations can help me achieve this and what would this field of study be called?
----------

I am not aware of a specific professional for every sense.

Seeing = Opthamalogist (Physician); or Optometrist (non-physician)

Hearing = Otolaryngologist (ENT)(Physician); or Audiologist (non-physician)

Taste/Olfactory issues? I don't know but my best guess would be ENT again. Perhaps there are some really specialized Speech-Language Pathologists that deal with taste and olfactory things.

I don't know about touch at all. Perhaps certain neurologists?  (+ info)

What would happen to olfaction if mucus glands below the olfactory epithelium were absent?"?


I remember answering this question a day ago:

Anosmia would occur.. absence of smell sensation.  (+ info)

What foods causes or can CANCEL gastrointestinal olfactory releases?


That's gas for short.
----------

Broccoli, Cheese, Beans, Peas,etc.  (+ info)

How common are olfactory hallucinations (phantosmia)?


How common are they and what is the most common cause?
----------

Many people are sensitive to certain smells, but in an olfactory hallucination (phantosmia), you detect smells that are not really present in your environment. The smells detected in phantosmia vary from person to person, but may include foul odors such as rotting food or pleasant odors such as fresh flowers. Phantosmia may progress to olfactory delusions, a condition in which you persistently believe that the smell and its source exist, even though they do not.

Most often phantosmia is due to temporal lobe seizures, but it could also be caused by a brain injury. If you have a temporal lobe seizure, your phantosmia may be brief and you may lose consciousness or have other symptoms of epilepsy.

The combination of phantosmia and olfactory delusions is often due to a psychiatric illness, such as depression or schizophrenia. Phantosmia and olfactory delusions may also occur in people with Alzheimer's disease. Although rare, phantosmia can occur as part of the symptoms that you may experience before a migraine headache.

Because phantosmia could be a sign of a serious illness, talk to your doctor if you experience symptoms.  (+ info)

Have you ever known anyone to have olfactory hallucinations? ?


Is "imagining smells", in an otherwise physically and mentally perfectly healthy person, necessarily a sign of psychiatric problems? What specialist should he be taken to see? Genuinely helpful answers will be greatly appreciated.

stroke is the first thing that came in my mind but you said you are healthy. take some zinc  (+ info)

How can I know with a visual and olfactory inspection of her labia and vagina if a girl has an STD?


You can't. The only sure way of knowing if a girl has an STD is having her tell you or if she goes and gets tested or something.

Most STDs have no signs or symptoms or can take several months and even years for symptoms to show up!

Herpes for example has no signs or symptoms unless the person is currently on an outbreak. Then they would have sores. But, if they aren't having an outbreak the vagina and skin look normal.

HPV can cause warts on the vagina. But sometimes the warts are so small or so far into the vagina (like on the cervix) it's impossible to see them.  (+ info)

is it that when you are sick(common cold and flu) your taste bud and olfactory sense are dulled and different?


why when i am sick that time , i smoke marlboro menthol . and the taste is different from when i am not ill
----------

Taste is effected and influenced by sight and smell.

When you have any sinus blockages such as when we have a cold or flu, the sense of taste changes as the body can no longer use it main senes'.

Also feeling unwell alters the taste buds at times. Which is why you get a sore, dry tongue and a horrible taste in your mouth.  (+ info)

What are olfactory & pulmonary diseases? Are they related with environmental pollution? How?


There have been many studies about the relationship between environmental toxins and illness/disease including those you speak of. I think that all of us are in danger of being clogged by impurities. I suggest nutritional cleansing to remove those toxins on a regular basis and allowing your body to return to being the miracle it was intended to be. The best I found on the market is the 30-day cleansing system from Isagenix.  (+ info)
