“…The training group (n=40) significantly improved their psychophysical test scores (Sniffin’ Sticks) after 12 weeks, while the non-training group (n=16) did not. This result has since been repeatedly confirmed, although rarely in controlled trials 371 372 .…”

ZusammenfasssungDer Geruchssinn ist wichtig. Das wurde insbesondere v. a. Patient:innen mit infektbedingtem Riechverlust während der SARS-CoV2 Pandemie bewusst. Wir reagieren z. B. auf Körpergerüche unserer Mitmenschen – die Nase bestimmt/wen wir „riechen können“. Der Geruchssinn warnt uns vor Gefahren, die Wahrnehmung von Düften und die Wahrnehmung von Aromen beim Essen bedeuten Lebensqualität. Eine Anosmie muss daher ernst genommen werden. Obwohl sich olfaktorische Rezeptorneurone durch Regenerationsfähigkeit auszeichnen, sind Anosmien mit etwa 5% relativ häufig. Riechstörungen werden nach der Ursache eingeteilt (z. B. Infekte, Schädelhirntraumen, chronische Rhinosinusitis, Alter) mit den sich daraus ergebenden unterschiedlichen Therapieoptionen und Prognosen. Eine gründliche Anamnese ist deshalb bedeutsam. Zur Diagnostik stehen verschiedenste Untersuchungsverfahren zur Verfügung, von orientierenden Kurztests über ausführliche mehrdimensionale Testverfahren bis hin zu elektrophysiologischen und bildgebenden Methoden. Damit sind quantitative Riechstörungen gut erfassbar und nachverfolgbar. Bei qualitativen Riechstörungen wie der Parosmie stehen derzeit allerdings keine objektivierenden Diagnoseverfahren zur Verfügung. Die therapeutischen Möglichkeiten bei Riechstörungen sind begrenzt. Trotzdem stehen mit dem Riechtraining sowie verschiedenen additiven medikamentösen Möglichkeiten wirksame Optionen zur Verfügung. Von großer Bedeutung ist nach wie vor die Beratung und das kompetente Gespräch mit den Patient:innen.

“…Die Trainingsgruppe (n = 40) verbesserte nach 12 Wochen ihre psychophysischen Testergebnissen (Sniffin' Sticks) signifikant, während dies bei der Nicht-Trainingsgruppe (n = 16) nicht der Fall war. Dieses Ergebnis wurde seither wiederholt bestätigt, allerdings selten in kontrollierten Studien [371,372].…”

“…In addition, olfactory disfunction may be related to depression [ 56 ] and neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease [ 57 ]. Therefore, the olfactory training is expected to have various effects [ 58 ]. For instance, in older people, the olfactory training was found to improve semantic verbal fluency and decrease the severity of depressive symptoms in individuals with subclinical depression [ 16 ].…”

Recent studies revealed that grey matter (GM) changes due to various training and learning experiences, using magnetic resonance imaging. In this study, we investigate the effect of psychological characteristics and attitudes toward training and learning on GM changes. Ninety participants were recruited and distributed into three groups: an olfactory training group that underwent 40 olfactory training sessions designed for odour classification tasks, a group classified for learning of neuroplasticity and brain healthcare using a TED Talk video and 28 daily brain healthcare messages, and a control group. Further, we assessed psychological characteristics, such as curiosity and personal growth initiatives. In the olfactory training group, we conducted a questionnaire survey on olfactory training regarding their interests and sense of accomplishment. In the olfactory training group, the GM change was significantly correlated with the sense of achievement and interest in training. The learning of neuroplasticity and brain healthcare group showed a significantly smaller 2-month GM decline than did the control group. The Curiosity and Exploration Inventory-II scores were significantly correlated with GM changes in both intervention groups only. In conclusion, our result suggested that training or learning with a sense of accomplishment, interest, and curiosity would lead to greater GM changes.

“…Additionally, our results regarding olfactory training showed significant olfactory improvement among patients before and after training by the Iran-SIT, QOD, and self-assessment tools. Olfactory training has positive effects on olfactory loss with different causes, which can be considered an established method for smell rehabilitation [ 18 ]. Also, the results showed a more potent effect of olfactory training compared to curcumin, proving that olfactory training improves the olfactory sense of patients even more than curcumin.…”
