hyposmia

It is estimated that up to 4 million people in the United States have hyposmia or the related anosmia.

Only one half of the patients suffering from anosmia and hyposmia perceive their deficit, even when they are specifically asked to do so.

Lifelong hyposmia could be caused by Kallmann syndrome.

Reduction or loss of sense of smell (hyposmia or anosmia).

Reduced sense of smell (hyposmia) suggests Kallmann syndrome.

Other olfactory disorders such as hyposmia and anosmia have been found to be a symptom of mood disorders (depression).

A related term, hyposmia, refers to a decreased ability to smell, while hyperosmia refers to an increased ability to smell.

It is characterised by hypogonadism and by a total lack of sense of smell (anosmia) or a heavily reduced sense of smell (hyposmia).

This theory is supported indirectly by the fact that patients with Parkinson's Disease have an increase in dopaminergic cells in the olfactory bulb and usually exhibit hyposmia.

There have been experiments done to treat parosmia with L-Dopa, but besides that there are no current treatments other than inducing anosmia or hyposmia to the point where the odors are negligible.

Anosmia and hyposmia (a less severe form of anosmia with a decreased sensitivity to smell but not the complete lack of it) are more quantitative disabilities typified by degrees in which the odor is sensed.

In Kallmann syndrome the olfactory bulb is missing or not fully developed which gives rise to the additional symptom of lack of sense of smell (anosmia) or vastly reduced sense of smell (hyposmia).
