Nutritional counseling may be helpful since some foods and spices which are most likely to stimulate the receptors (trigeminal and olfactory chemoreceptors.). The odors detected in phantosmia vary from person to person and may be foul or pleasant. A link between your inner ear and your brain helps you keep your balance when you get out of bed or walk over rough ground. There are several terms that are used to describe the different types of smell disorders. According to recent neuropathological staging concepts, impaired olfaction is assumed to indicate an early pathological process and might be associated with structural changes in the brain. Although there are over 200,000 visits to physicians each year for chemosensory disorders, many of these problems tend to be dismissed by patients as well as by physicians.
