BACKGROUND AND PURPOSE Anosmia frequently occurs after aneurysmal subarachnoid hemorrhage not only after clipping, but also after endovascular coiling. Thus, at least in part, anosmia is caused by the hemorrhage itself and not only by surgical treatment. However, it is unknown whether anosmia is related to rupture of the aneurysm with sudden increase in intracranial pressure or to the presence ...

BACKGROUND AND PURPOSE Anosmia occurs frequently in patients with subarachnoid hemorrhage (SAH) from a ruptured aneurysm treated with clipping. We analyzed prevalence, prognosis, and potential risk factors for anosmia after coiling for SAH. METHODS We interviewed all patients who resumed independent living after SAH treated with coiling between 1997 and 2007. We assessed by means of logistic ...

BACKGROUND Olfactory abnormalities are reported in Alzheimer's disease and Parkinson's disease. Anosmia appears to be common in dementia with Lewy bodies but not in pure Alzheimer's disease. OBJECTIVE To determine whether anosmia improves discrimination between the Lewy body variant (LBV) of Alzheimer's disease and "pure" Alzheimer's disease. METHODS 106 cases of necropsy confirmed pure Alz...

I solated congenital anosmia (MIM 107200) is a very rare condition characterised by a complete smelling defect that is present from birth in otherwise normal subjects. To our knowledge, nine sporadic cases of isolated congenital anosmia have been known, 2 and patients reported by Lygonis and those by us were only familial isolated congenital anosmia. Other cases of familial congenital anosmia h...

There are many cases of smelling disorders, which can impact an individual’s ability to smell. In addition, it’s important to understand there is a whole population among us who cannot smell (anosmia), who may have grown up never smelling (congenital anosmia), or who have reduced smell (hyposmia). Because the sense of smell is not as severe, life-threatening, or well-known, it is not widely stu...

Reports about fluctuating olfactory deficits are rare, as are reports of unilateral olfactory loss. We present a case of unilateral anosmia with contralateral normosmia, presenting as rapidly fluctuating anosmia. The olfactory fluctuation occurred in sync with the average nasal cycle duration. Examination after nasal decongestion, formal smell testing, and imaging revealed unilateral, left-side...

Background The olfactory bulb is anatomically exposed and thus can be directly damaged by external stimulation. This can occur as an occupational injury owing to contact with organic solvents or other causes. We present cases of eight patients who sustained occupation-related exposure to potentially toxic substances and later presented with signs and symptoms of anosmia. We examined the occupat...
