ABSTRACT Background Olfactory training (OT) is a recommended treatment for olfactory loss and has proven effective in clinical contexts, yet its effects on the central‐nervous system remain unclear. This study aimed to investigate functional structural brain changes patients with post‐viral undergoing OT. Methods Twenty 19 healthy controls underwent OT 3 months. All participants were assessed using Sniffin’ Sticks test magnetic resonance imaging (MRI). Voxel‐based morphometry bulb volumetry...
Variability in human olfactory sensitivity has been attributed to individual-level factors such as genetics, age, sex, medical history of infections and trauma, neurogenerative diseases, emotional disorders. Scarce evidence exists on the cross-cultural variation sensitivity. Hence, we performed 2 studies estimate variability threshold a function location environment. Study 1 involved 11 laboratories from 4 continents (N = 802). In each location, designated laboratory, approximately 80...
Smell perception plays an important role in eating behavior and might be involved body weight gain. Since a of literature implies that olfactory function is hampered obesity, we here investigate neuroanatomical correlates this phenomenon. We assessed bulb (OB) volume with magnetic resonance imaging 67 healthy participants mass index (BMI) from 18.9 to 45.4 kg/m 2 (mean = 28.58 ± 6.64). Moreover, obtained psychophysiological data on ability (Sniffin’ Sticks, Food associated odor test)...
The olfactory bulb (OB) plays a key role in the processing of information. A large body research has shown that OB volumes correlate with function, which provides diagnostic and prognostic information dysfunction. Still, potential value shape remains unclear. Based on our clinical experience we hypothesized predicts it is linked to loss, age, gender. aim this study was produce classification human brain, scalable applications. Results from patients five most frequent causes dysfunction (n =...
Abstract Well‐being (WB) is defined as a healthy state of mind and body. It consists mental, physical, social domains. In our everyday life, we perceive millions odors from environment, which have role in communication, protecting us the environmental hazards quality life. A lot known about association between olfaction depression; however, relation WB remains unexplored. study, reanalyzed 122 subjects (mean age 26 ± 3 years; 58 men/64 women). was examined using 42‐item, General habitual...
Abstract Purpose The diagnosis of olfactory dysfunction is mainly based on psychophysical measurements. aim the current study was to investigate how well functional magnetic resonance imaging (fMRI) can effectively distinguish between normosmic people and subjects with dysfunction. Methods Thirty-eight participants were recruited for study. Group 1 consisted 22 (mean age = 44.3 years, SD 18.6), two 16 normal function 49.6 11.6). Olfactory functions assessed in great detail all participants,...
Background Cribriform foramina provide the openings for olfactory nerve fibers to cross from nasal cavity bulb. Disruption of is known affect function, but little about potential effects on number cribriform in congenital anosmia. Objective This pilot study aimed investigate whether there was a reduction patients with acquired and anosmia (including both Kallmann syndrome isolated anosmia) compared controls normal function. Methods Paranasal CT image stacks were analyzed 20 ( n = 6), or...
Background To introduce new ways to calculate OB volumes, checking their validity and comparing them already established technique i.e. volumetric based on manual segmentation of boundaries. Methods Two approaches were used volumes (1) Manual Segmentation using planimetric contouring; (2) Box-frame method, calculating the parameters a box placed around OB. Results We calculated both techniques found comparable outcomes. High inter-observer reliability was for by observers. For segmentation,...
Much is known about the effect of odors on mood, cognition and behavior, but little relationship between well-being. We investigated neural processing with different degrees association well-being (WB) through two large independent datasets. The study encompassed pre-testing fMRI. During pre-testing, 100 80 (studies 1 2) young, healthy subjects participated, rating intensity, valence, WB for 14 (study 1) 8 odors. Pre-testing resulted in selection high (WB-associated) lower (neutral odors)...
Odorous sensations are based on trigeminal and olfactory perceptions. Both stimuli generate overlapping as well distinctive activations in the cortex including piriform cortex. Orbitofrontal (OFC), an integrative center for all senses, is directly activated presence of stimulations. In contrast, thalamus, a very important midbrain structure, not odors, but rather acts relay portions information between primary higher-order processing centers. The aims study were (1) to examine number...
Olfactory loss can be acquired (patients with a history of olfactory experiences), or inborn without experiences/life-long inability to smell). Inborn loss, congenital anosmia (CA), is relatively rare and there knowledge gap regarding the compensatory neural mechanisms involved in this condition. The study aimed investigate top-down processing patients CA idiopathic (IA) comparison normosmia controls (NC) during expectancy reading odor-associated words. Functional magnetic resonance imaging...
The olfactory bulbs (OBs) play a key role in processing; their volume is important for diagnosis, prognosis and treatment of patients with loss. Until now, measurements OB volumes have been limited to quantification manually segmented OBs, which cumbersome task makes evaluation large scale clinical studies infeasible. Hence, the aim this study was evaluate potential our previously developed automatic segmentation method application practice relate results outcome measures. To utilization...
In a previous neuroimaging study, patients with taste loss showed stronger activations in gustatory cortices compared to people normal function during stimulations. The aim of the current study was examine whether there are changes central-nervous functional connectivity loss.We selected 26 pairs brain regions related processing as our interests (ROIs). Functional magnetic resonance imaging (fMRI) used measure responses seven and 12 healthy controls they received stimulations (taste...
Introduction Migraine is a leading cause of disability and suffering worldwide. However, conventional pharmacological migraine preventive therapies are often challenging accompanied by adverse effects. Recently, structured odour exposure has shown to successfully increase pain thresholds in patients with chronic back pain. Despite the importance olfactory system migraine, there no studies investigating impact migraine. Methods analysis This double-blind randomised placebo-controlled trial...
Well-being (WB) is defined as a healthy state of mind and body. It in which an individual able to contribute its society, work productively overcome the normal stress life. WB multi-dimensional concept covers different aspects, including life satisfaction quality Little known whether there are differences connectivity patterns between individuals with states. We evaluated no prior diagnosis any psychological disorder using "General habitual questionnaire", covering mental, physical social...
