UNLABELLED The idiopathic Parkinson disease (IPD) is traditionally diagnosed by motor signs, but non-motor symptoms and signs are frequent and may help in the clinical diagnosis. PURPOSE To evaluate the olfactory function in Brazilian healthy subjects, patients with early-onset PD (EOPD) and late-onset PD (LOPD) using the Sniffin' Sticks odor-identification test (SST). METHOD We studied 70 ...

Various olfaction tests are used clinically in the world. In Japan, T&T olfactometry and the intravenous olfaction test, the Alinamin® test, are used as a standardized olfactory test in otorhinolaryngology clinics (Zusho, 1983; Furukawa et al., 1988). In Western countries, the University of Pennsylvania Smell Identification Test (UPSIT), the Cross-cultural Smell Identification Test (CC-SIT) and...

Barth syndrome is a rare X-linked disease affecting less than 200 individuals worldwide. Several comorbidities have been associated with the pathology and, among those, cardiac myopathy and neutropenia are the most life threatening. The appropriate nutritive support is important to sustain the everyday life of Barth syndrome patients given the chronic fatigue they experience. Since they often p...

Olfactory sensitivity varies between individuals. However, data regarding cross-cultural and inter-group differences are scarce. We compared the thresholds of odor detection of the traditional society of Tsimane' (native Amazonians of the Bolivian rainforest; n = 151) and people living in Dresden (Germany; n = 286) using "Sniffin' Sticks" threshold subtest. Tsimane' detected n-butanol at signif...

When a patient loses visual ability, new synapses may develop in the brain to adapt to new situations and sustain life with other sensory organs. We appreciate the article titled “Olfactory Function Assessment of Blind Subjects Using the Sniffin’ Sticks Test,” written by Çomoğlu et al. In this study, olfactory functions were found to be better in blind patients than in normal individuals. Enhan...
