Abstract Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 chemosensory impairments, such as anosmia. However, these downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, generally lacked quantitative measurements. Here, we report the development, implementation, initial results multilingual, international questionnaire assess self-reported quantity quality perception in 3 distinct modalities (smell, chemesthesis) before...
Abstract In a preregistered, cross-sectional study, we investigated whether olfactory loss is reliable predictor of COVID-19 using crowdsourced questionnaire in 23 languages to assess symptoms individuals self-reporting recent respiratory illness. We quantified changes chemosensory abilities during the course illness 0–100 visual analog scales (VAS) for participants reporting positive (C19+; n = 4148) or negative (C19−; 546) laboratory test outcome. Logistic regression models identified...
Abstract In response to the COVID-19 pandemic, many governments have taken drastic measures avoid an overflow of intensive care units. Accurate metrics disease spread are critical for reopening strategies. Here, we show that self-reports smell/taste changes more closely associated with hospital overload and earlier markers infection SARS-CoV-2 than current governmental indicators. We also report a decrease in new onset as early 5 days after lockdown enforcement. Cross-country comparisons...
A wealth of rapidly evolving reports suggests that olfaction and taste disturbances may be manifestations the novel COVID-19 pandemic. While otolaryngological societies worldwide have started to consider chemosensory evaluation as a screening tool for infection, true nature relationship between changes in ability is unclear. Our goal with this review provide brief overview published archived literature, well anecdotal social trends related topic up April 29, 2020. We also aim draw parallels...
(1) Background: Persistent olfactory (POD) and gustatory (PGD) dysfunctions are one of the most frequent symptoms long-Coronavirus Disease 2019 but their effect on quality life (QoL) patients is still largely unexplored. (2) Methods: An online survey was administered to individuals who reported have had SARS-CoV-2 infection at least 6 months prior with persisting COVID-19 (using COVID symptom index), including ratings POD PGD, physical (PCS) mental (MCS) components were assessed using...
The ability to detect conspecifics that represent a potential harm for an individual represents high survival benefit. Humans communicate socially relevant information using all sensory modalities, including the chemosensory systems. In study 1, we investigated whether body odor of stranger with intention serves as chemosignal aggression. Sixteen healthy male participants donated their while engaging in boxing session characterized by aggression-induction methods (chemosignal aggression) and...
It is estimated that 20%-67% of those with COVID-19 develop olfactory disorders, depending on the SARS-CoV-2 variant. However, there an absence quick, population-wide tests to screen for disorders. The purpose this study was provide a proof-of-concept SCENTinel 1.1, rapid, inexpensive, test, can discriminate between anosmia (total smell loss), hyposmia (reduced sense smell), parosmia (distorted odor perception), and phantosmia (odor sensation without source). Participants were mailed 1.1...
The vast majority of humans are right-handed, but how and when this bias emerges during human ontogenesis is still unclear. We propose an approach that explains postnatal handedness starting from 18 gestational weeks using a kinematic analysis different fetal arm movements recorded ultrasonography. Based on the hand dominance reported postnatally at age 9, fetuses were classified as right-handed (86%) or left-handed, in line with population data. revealed both left-handed faster to reach...
Abstract Commercially available smell tests are primarily used in research or in-depth clinical evaluations and too costly time-consuming for population surveillance health emergencies like COVID-19. To address this need, we developed the SCENTinel 1.0 test, which rapidly evaluates 3 olfactory functions: detection, intensity, identification. We tested whether self-administering test discriminates between individuals with self-reported loss those average ability (normosmic individuals)...
Millions of people in the United States experience a reduced or distorted ability to smell taste. Chemosensory disorders such as anosmia (the inability smell), parosmia (distorted dysgeusia (altered taste) have major impacts on health and quality life including difficulty sensing dangers fire spoilage, diminished palatability food drink that can negatively influence diet nutrition, feelings social isolation, an increased incidence frailty, anxiety, depression. Smell taste dysfunction also be...
Background Evidence suggests that subliminal odorants influence human perception and behavior. It has been hypothesized the sex-steroid derived compound 4,16-androstadien-3-one (androstadienone) functions as a chemosignal. The most intensively studied steroid compound, androstadienone is known to be biologically relevant since it seems convey information about male mate quality women. unclear if effects of are menstrual cycle related. Methodology/Principal Findings In first experiment,...
Odor detection sensitivity can be rapidly altered by fear conditioning; whether this effect is augmented over time not known.The present study aimed to test repeated conditioning sessions induce changes in odor threshold as well conditioned responses and olfactory stimuli evoke stronger than visual stimuli.The group participated 2 weeks whereas the single 1 session; both groups were presented with stimuli, paired an electric shock (CS+) matched control (CS-) while skin conductance (SCRs)...
Identifying triggers for challenging behavior is difficult in some children with autism because of their limited communication abilities. Physiological indicators stress may provide important insights. This study examined whether heart rate (HR) predicts autism. While wearing an electrocardiograph monitor, 41 aged 2- to 4-years participated tasks designed induce low-level (e.g. waiting a snack). Coders identified 106 time periods during which behaviors occurred and also coded randomly...
Abstract Morality evolved within specific social contexts that are argued to shape moral choices. In turn, choices hypothesized be affected by body odors as they powerfully convey socially-relevant information. We thus investigated the neural underpinnings of possible effect on participants’ decisions. an fMRI study we presented healthy individuals 64 dilemmas divided in incongruent (real) and congruent (fake) dilemmas, using different types harm (intentional: instrumental or inadvertent:...
Abstract Odors can increase memory performance when presented as context during both encoding and retrieval phases. Since information from different sensory modalities is integrated into a unified conceptual knowledge, we hypothesize that the social body odors faces would be encoding. The integration of such enhance more so than occurs in common odors. To examine this hypothesis to further explore underlying neural correlates behavior, have conducted functional magnetic resonance imaging...
Abstract Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 chemosensory impairments such as anosmia. However, these downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, generally lacked quantitative measurements, were mostly restricted data from single countries. Here, we report the development, implementation initial results multi-lingual, international questionnaire assess self-reported quantity quality perception in...
Abstract Chemosensory impairments have been established as a specific indicator of COVID-19. They affect most patients and may persist long past the resolution respiratory symptoms, representing an unprecedented medical challenge. Since SARS-CoV-2 pandemic started, we now know much more about smell, taste, chemesthesis loss associated with However, temporal dynamics characteristics recovery are still unknown. Here, capitalizing on data from Global Consortium for Research (GCCR) crowdsourced...
