Olfactory dysfunction is among the earliest nonmotor features of Parkinson disease (PD).
Such dysfunction is present in approximately 90% of early-stage PD cases and can precede …

Increasing recognition that Parkinson's disease (PD) may start outside of the substantia
nigra has led to a rapidly expanding effort to define prodromal stages of PD, before motor …

Brains of 42 individuals between the ages of 4 and 29 were examined with antibodies (AT8,
4G8) and silver stains for the presence of intraneuronal and extracellular protein aggregates …

Olfactory deficits are present in numerous neurodegenerative disorders and are
accompanied by pathology in related brain regions. In several of these disorders, olfactory …

Olfactory dysfunction is an early 'pre-clinical'sign of Parkinson's disease (PD). The present
review is a comprehensive and up-to-date assessment of such dysfunction in PD and …

Olfactory dysfunction is a common and early symptom of many neurodegenerative diseases,
particularly of Parkinson's disease and other synucleinopathies, Alzheimer's disease (AD) …

We have developed a simple colorimetric sensor array that detects a wide range of volatile
analytes and then applied it to the detection of toxic gases. The sensor consists of a …

The impact of health, management, and microbiota on olfactory function in canines has not
been examined in review. The most important characteristic of the detection canine is its …
