“…There are other factors that ought to be taken into consideration when assessing the results. Age (Hudson et al, 2012 ; Sorokowska et al, 2015 ) and gender (Doty and Cameron, 2009 ; Malaspina et al, 2012 ) have been found to be associated with changes in olfaction. It has been found to be higher in adults (up to a certain age) and women (Mullol et al, 2012 ).…”

Olfaction in eating disorders and abnormal eating behavior: a systematic review

The study provides a systematic review that explores the current literature on olfactory capacity in abnormal eating behavior. The objective is to present a basis for discussion on whether research in olfaction in eating disorders may offer additional insight with regard to the complex etiopathology of eating disorders (ED) and abnormal eating behaviors. Electronic databases (Medline, PsycINFO, PubMed, Science Direct, and Web of Science) were searched using the components in relation to olfaction and combining them with the components related to abnormal eating behavior. Out of 1352 articles, titles were first excluded by title (n = 64) and then by abstract and fulltext resulting in a final selection of 14 articles (820 patients and 385 control participants) for this review. The highest number of existing literature on olfaction in ED were carried out with AN patients (78.6%) followed by BN patients (35.7%) and obese individuals (14.3%). Most studies were only conducted on females. The general findings support that olfaction is altered in AN and in obesity and indicates toward there being little to no difference in olfactory capacity between BN patients and the general population. Due to the limited number of studies and heterogeneity this review stresses on the importance of more research on olfaction and abnormal eating behavior.

Objectives: Treatment for olfactory dysfunction is challenging due to limited therapeutic options. Olfactory training has shown improvement in smell identification, discrimination, and threshold for odor detection. The primary objective is to assess the effect of olfactory training in patients with olfactory dysfunction after pituitary surgery, using functional Magnetic Resonance Imaging (fMRI). Design: This study was designed as a two-arm pilot clinical trial. Setting: Chilean tertiary hospital providing endoscopic pituitary surgery and olfactory evaluation and treatment. Participants: We included two cohorts of subjects: healthy subjects, and patients with post-surgical olfactory dysfunction. Healthy patients were recruited voluntarily at the ENT clinic to assess fMRI testing paradigms and as a control group for the olfactory dysfunction group. Main outcome measures: The main outcome measures were functional activation analysis obtained by fMRI. Olfactory test assessment scores were also obtained during each testing session. Results: 119 patients that underwent an endoscopic transsphenoidal approach were contacted and surveyed for olfactory dysfunction. Twelve patients met inclusion criteria, but six of them declined to participate. Six patients were randomized using computer-generated random numbers. The patients in the trained group showed a significant improvement in the olfactory test results after olfactory training compared to the no-training group (P < 0.05). The group that underwent olfactory training showed more areas of activation after training than in baseline analysis (P < 0.05). Conclusion: Patients that underwent olfactory training showed significant improvement in olfactory testing. fMRI results showed more activated areas in the olfactory training group, which could be compatible with neuroplasticity.

“…El café es reconocido por 70 a 90% y la canela por más de 50% de los participantes en estudios brasileros, mexicanos y chilenos. [16][17][18][19] A diferencia del café y la canela, el azúcar y los clavos fueron pobremente identificados. No obstante, estos últimos fueron reconocidos por más de 50% de los sujetos de algunos subgrupos, como las personas con un nivel de escolaridad superior.…”

“…En este estudio, el reconocimiento de los clavos fue menor al de otras muestras latinoamericanas en las que al menos 59% reconocieron este olor. [16][17][18][19][20] El azúcar fue el olor con un menor número de aciertos. En nuestro estudio se utilizaron presentaciones comerciales individuales, mientras que históricamente se han utilizado grandes cantidades de azúcar para evaluar el olfato.…”

Introducción: la hiposmia es un marcador temprano de algunas enfermedades neurodegenerativas. Las pruebas de identificación de olores son costosas y contienen olores poco conocidos en algunas culturas. Es importante estandarizar pruebas de fácil aplicación en países hispanohablantes. Material y métodos: estudio observacional descriptivo de identificación de los olores a café, clavos, canela y azúcar en 100 adultos sin enfermedades que afecten la olfacción. Se evaluaron los olores contenidos en empaques comerciales individuales y se registró la respuesta libre dada por cada sujeto. Resultados: el café y la canela fueron identificados por 83 y 71% de los sujetos, respectivamente. Los clavos y el azúcar fueron pobremente identificados. Por encima de los 60 años, menos de 2/3 de las personas reconocieron el café y la canela. Conclusiones: la mayoría de sujetos identifican dos de los cuatro olores contenidos en esta prueba y proponemos que sujetos con identificación de uno o ningún olor deberían someterse a una evaluación exhaustiva. El efecto de la edad, también descrito en otras publicaciones, sugiere que en sujetos de mayor edad sería necesario utilizar pruebas con más número de olores para diferenciar entre la pérdida de olfato asociada a la edad y la hiposmia asociada a enfermedad neurodegenerativa.
