OBJECTIVE To investigate the impact of the use of more contrasted distractors on correct odor identification in patients with olfactory loss. DESIGN Randomized, cross-over study. SETTING University clinic. PATIENTS Thirty patients with olfactory deficits. INTERVENTIONS The olfactory function of the patients was evaluated by means of the "Sniffin' Sticks" test battery. MAIN OUTCOME MEA...

Objectives: This study is aimed to investigate the frequency of olfactory dysfunction in Parkinson’s Disease (PD) and its relationship with motor/non-motor symptoms treatment comparison isolated patients healthy controls.Methods: includes 40 PD patients, 37 anosmia 42 controls. are evaluated evaluation form including; sociodemographic features, disease history, Unified Rating Scale (UPDRS) scor...

OBJECTIVE Decrease of olfactory function in Parkinson's disease (PD) is a well-investigated fact. Studies indicate that pharmacological treatment of PD fails to restore olfactory function in PD patients. The aim of this investigation was whether patients with PD would benefit from "training" with odors in terms of an improvement of their general olfactory function. It has been hypothesized that...

BACKGROUND The aim of this study was: (1) to perform a preliminary study for the validation of ''retronasal olfactory testing'' in the Turkish population to find the best way to evaluate smell and taste disorders in Turkey; (2) to determine if cultural differences make application of the test more difficult; and (3) to determine the flavors that participants had not yet tasted by using the surv...

'Sniffin' Sticks' is a new test of nasal chemosensory performance based on pen-like odor dispensing devices. It comprises three tests of olfactory function, namely tests for odor threshold (n-butanol, testing by means of a single staircase), odor discrimination (16 pairs of odorants, triple forced choice) and odor identification (16 common odorants, multiple forced choice from four verbal items...

PURPOSE The aim of this study was to quantify the ability to identify odors in normal tension glaucoma (NTG) patients and healthy subjects with and without a primary vascular dysregulation (PVD). METHODS Both self-assessment of smell perception and evaluation of odor identification by means of the 12-item odor identification test ("Sniffin' Sticks") were performed in the following groups of s...

OBJECTIVE In recent years, a growing number of studies have focused on the olfactory abilities of blind individuals as well as their tactile and auditory senses. In this study, we aimed to investigate possible alterations in the sense of smell in early- and late-blind subjects as compared with sighted controls, using a Sniffin' Sticks test battery. STUDY DESIGN Prospective clinical study. S...

To the Editor: Monitoring of olfactory function and diagnosis disorders using pen-based “Sniffin' Sticks test” is problematic during SARS-CoV-2 pandemic due to hygienic concerns. The aim this study was find out whether results testing obtained by presenting odours on a single-use filter paper identical performing test odour pens according manufacturer’s manual.

The "Sniffin' Sticks" test kit is a validated and commonly used tool for assessment of olfactory function in subjects with normal sense of smell and in individuals with smell loss. That test incorporates subtests for odor threshold, discrimination, and identification. To gain higher subtest reproducibility, tests on odor discrimination and odor identification were extended using 32 instead of t...
