Taste and smell disorders have multiple causes. We describe a patient in whom atrial fibrillation and subsequent embolic stroke was discovered because of complaints of decreased smell and taste. These deficits ultimately improved after treatment of the atrial fibrillation along with anticoagulation medication for stroke prevention.

Disturbances of olfaction are a common occurrence in many neurological and neurosurgical patients and their correct diagnosis might be helpful in management and enhancement of quality of life. However, olfaction is seldom checked in most neurosurgical units and the "smell bottles" are often either absent or out of date. This chapter reviews systematically recent advances in our understanding of...

Sense of smell, often called olfaction, is a significant way for vertebrate animals that have ‘the nose’ to recognize the chemical signals from their environment. Generally, olfaction of the nose is the most important sense for the majority of vertebrate animals to maintain their survival with the exception of several mammals, including humans. Human’s ability to smell is significantly weaker t...

Olfaction is an important mechanism by which humans and animals communicate with environment. Odorant-binding proteins (OBPs) play crucial role in the olfactory mechanism. Here, we briefly discuss about the role of OBPs and their importance in industrial, pest management and therapeutic developments.

Olfaction is characterized by a salient hedonic dimension. Previous studies have shown that these affective responses to odors are modulated by physicochemical, physiological, and cognitive factors. The present study examined expertise influenced processing of pleasant and unpleasant odors on both perceptual and verbal levels. For this, performance on two olfactory tasks was compared between no...

It has long been recognized that olfaction and emotion are linked. While chemosensory research using both human and rodent models have indicated a change in emotion can contribute to olfactory dysfunction, there are few studies addressing the contribution of olfaction to a modulation in emotion. In mice, olfactory deficits have been linked with heightened anxiety levels, suggesting that there c...

Background Olfactory and affective factors are associated in a complex way, likely due to partial overlap brain regions involved. Although the role of olfaction disorders such as Parkinson Disease (PD) is documented, less clear association between psychological symptoms, anxiety, Mild Cognitive Impairment (MCI) elderly cognitively healthy controls (HCs). Also, sex differences symptoms pathologi...

The sense of olfaction reached its zenith in development much earlier than other special senses. Olfaction is much more acute than the other senses, exhibits both high sensitivity for odours and high discrimination between them. This plays a very important role even in the social and behavioral aspects of human beings. Recent studies using molecular genetics, electrophysiology and behavioral an...
