What this trial studies
This observational study aims to map the prevalence and characteristics of smell and taste disorders in the Belgian/Flemish population. It involves standard diagnostic tests and structured questionnaires to assess the severity, impact, and progression of these disorders. The initiative was launched in response to the increasing cases of smell dysfunction, particularly following COVID-19. Participants will provide informed consent and undergo psychophysical testing to contribute to a comprehensive registry.
Why it matters
Potential benefit: If successful, this study could enhance understanding and management of smell and taste disorders, leading to improved patient care.
How similar studies have gone: While similar observational studies have been conducted, this specific registry approach focusing on post-COVID-19 related disorders is relatively novel.
