Olfactory inversion

Introduction The olfactory inversion is to mistake an obvious odor as another odor, such as stinking odor as a scent, or odorless odor, called olfactory inversion. The olfactory inversion is manifested as a dislocation response to olfactory stimuli, but not accompanied by olfactory acuity. Patients with head trauma, spinal tuberculosis, psychosis, rickets, neurasthenia, and certain drugs, such as aminopyrine, often have olfactory inversion. In addition, some patients with loss of olfactory sensation will also experience olfactory inversion during the recovery period.

Cause

Inducing factors of olfactory inversion:

Patients with head trauma, spinal tuberculosis, psychosis, rickets, neurasthenia, and certain drugs, such as aminopyrine, often have olfactory inversion. In addition, some patients with loss of olfactory sensation will also experience olfactory inversion during the recovery period.

Olfactory inversion check

Olfactory inversion: manifested as a dislocation response to olfactory odor stimulation, but not accompanied by olfactory acute injury.

1. Cerebrospinal fluid examination.

2. Other necessary selective examination items include: blood routine, blood electrolytes, blood sugar, and urea nitrogen.

3. Bottom of the skull, CT and MRI.

4. Otolaryngology examination and olfactory examination.

5. Other necessary optional auxiliary examination items include chest X-ray and electrocardiogram.

Differential diagnosis

Symptoms of olfactory inversion and confusion:

(1) olfactory sensation: olfactory damage often manifests as a decrease in sensitivity to olfactory stimuli.

(2) Loss of smell: The severe olfactory damage of the day after tomorrow is manifested by the loss of response to olfactory stimuli.

(3) Lack of smell: Innate olfactory loss, manifested as no response to olfactory scent stimulation.

(4) Olfactory inversion: manifested as a dislocation response to olfactory odor stimulation, but not accompanied by olfactory acute injury.

(5) Fantasy: There is no objective scent irritating stimulus, but the patient smells an unpleasant smell that is difficult to describe.

(6) Olfactory sensation: increased sensitivity to olfactory odor irritation.
