Background: Olfaction is poorly characterized in COPD. To test the hypothesis that olfaction is reduced in COPD, we assessed olfaction with the “Sniffin’ Sticks” test and a questionnaire addressing olfaction in COPD and a corresponding control group in respect to age and sex.

It was hypothesised that schizophrenic patients tested for olfactory discrimination would show a left nostril deficit. 15 tested were slightly but not significantly better than a control group of 15.

Recent clinical studies have identified significant olfactory deficits in several neuropsychiatric disorders, notably Alzheimer's disease and Parkinson's disease. These have correlated with neurochemical and neuropathological studies of the olfactory system.

▪ Abstract The main and accessory olfactory systems have received considerable attention on the part of scientists and clinicians during the last decade, largely because of (a) quantum advances in understanding their genetically expressed receptor mechanisms, (b) evidence that their receptor cells undergo neurogenesis and both programmed and induced ...

Current Opinion in Neurobiology, 1993
Olfactory transduction in invertebrates seems to be similar to that in vertebrates. Three signalling systems involving activation of adenylate cyclase, phospholipase C and guanylate cyclase are present. A variety of second messengers, including cAMP, inositol 1,4,5-trisphosphate, diacylglycerol, nitric oxide and Ca2+, have been identified but their ...

Current Opinion in Neurobiology, 1995
Our understanding of olfaction has progressed rapidly in recent years as a result of the molecular genetic approaches being used to study this sensory system in a variety of model organisms. Considerable success has been achieved in identifying proteins of the mammalian signaling system that are analogous to those present in other sensory systems. More

Olfactory thresholds for acetone and vanillin and the unpleasantness rating of concentrated acetone were measured in 20 migraine sufferers and 21 controls. The olfactory threshold for vanillin was lower in migraine sufferers than in controls. In addition, patients who reported that odours frequently seemed stronger during attacks of migraine were able
