Globally, the term "cacosmia" refers to any unpleasant odor. In a narrower sense, this term is usually referred to as a fairly rare illusion of the olfactory nature, i.e.distortion or the so-called imaginary smell.
When a person's perception of odors changes, and changes to a negative side: familiar and pleasant smells, are illusory becoming disgusting.
Unfortunately, this condition has not been studied at present, in addition to everything, it differs little from olfactory hallucinations, and sometimes merges with them.
As is known, the cacosmia, the symptoms and treatment of which will be given below, exists in two versions. The subjective form of the disease is spoken in the event that the perversion of the sense of smell occurs in the absence of adequate irritation from the corresponding substances with a strong odor. The objective type of the described state, as a rule, basically contains a completely clear real reason, in the form of, say, putrefactive decomposition of exudate, etc.
Causes of the onset of a cacosmia
Due to the lack and ambiguity of the data on the disease in question, it is not possible to clearly identify the reasons for its occurrence today.
There is an opinion that the complex process of mistaken perception is not so much associated with the smell coming from a particular source as with the current state of health, but also with individual physiology, memory, emotions, etc.
But at the same time, there are many examples that confirm that illusions of odors arise in mentally and physically absolutely healthy people.
It is believed that the described ailment can occur for natural reasons unrelated to the psyche. In other words, this disease can be a consequence of common diseases( for example, caries, tonsillitis, sinusitis, etc.).
Illusion psychiatrists may be the result of a partial epileptic fit or one of the symptoms of hypothyroidism, Paget's disease, etc.
Olfactory illusions may result from partial epileptic seizure or one of the symptoms of hypothyroidism, Paget's disease, etc.
Manifestation of symptoms of cacosmia and treatment of
diseaseas a kakosmia, the manifestation of symptoms, as a rule, arises quite unexpectedly. At some point, the perception suddenly changes, and the patient begins to feel, for example, in the scent of citrus a rather well-distinguishable smell of burning( which is a relatively frequent occurrence) or to smell the sulfur in sharp spices.
Psychologists often face the fact that they are approached by people with stories about what is familiar and yesterday a pleasant substance( for example, perfume or soap) smells "wrong".
It may also happen that along with the distortion of the olfactory perception, the person will develop taste illusions.
As mentioned above, the described disease is extremely poorly understood. Due to this, any specific treatment for kakosmia by medical personnel has not yet been developed.
While it is generally accepted that when illusions of smell occur, it is necessary to try to establish their cause and, if it is revealed, to throw all available opportunities and forces to cure the underlying disease.
