Most concepts related to physiology and pathology of olfaction has been related to abnormalities in neural function related to changes in central nervous system disorders or in disorders of olfactory nerves. While these events have been useful in understanding olfactory physiology and pathology most pathology of olfactory detection lies in problems related to olfactory receptor function not to ...

Abstract Purpose of Review This study aims to summarize and critically review recent literature on management post-traumatic olfactory dysfunction (PTOD) with emphasis the diagnostic procedure treatment options. Recent Findings Magnetic resonance imaging testing are basis procedure. Time diagnosis is critical as most improvement occurs within first year after trauma. Olfactory training oral ste...

Post-traumatic stress disorder (PTSD) is a mental health condition that's triggered by a terrifying event - either experiencing it or witnessing it. In addition to the relationship between PTSD and neuroinflammation, research indicates that olfactory bulb are effective in anxiety disorders. The aim of this study was to assess the electrophysiological activity of olfactory bulb in the animal mod...

Smell loss originates from peripheral disorders, like intranasal obstruction and olfactory cell injury, as well as central pathway diseases. Information derived from electrophysiological and psychophysical tests are useful for identifying loss of smell, but not for discriminating between central and peripheral deficits. This is because conventional imaging modalities are unable to deliver infor...

BACKGROUND: This cross-sectional, multi-centric study aimed to investigate the differences in quality of life among patients with olfactory dysfunction (OD) different origin, and identify factors associated olfactory-related (QOL). METHODS: Seven hundred sixty-three adults were recruited from 8 Smell & Taste clinics Germany, Switzerland, Austria. Olfactory-related QOL was assessed by Questi...

Olfactory deficits are present in numerous neurodegenerative disorders and are accompanied by pathology in related brain regions. In several of these disorders, olfactory disturbances appear early and are considered as prodromal symptoms of the disease. In addition, pathological protein aggregates affect olfactory regions prior to other regions, suggesting that the olfactory system might be par...

Olfactory identification ability and the prevalence of olfactory hallucinations were examined in 183 hospitalized patients from three diagnostic groups. One hundred and thirty-one patients with schizophrenia, 21 patients with major depression, 31 women with eating disorders along with 77 normal control subjects were examined using the University of Pennsylvania Smell Identification Test (UPSIT)...
