Summary
Olfactory dysfunction is common among patients with Corona-Virus-Infection-Disease (COVID)-19, and up to 30% of patients may report persistent disorders of smell or taste as a long-term sequelae. This randomized-controlled study has addressed to compare the efficacy of neuro-protective and anti-inflammatory agents palmitoylethanolamide (PEA) and Luteolin(Treatment) with control (olfactory training) in a cohort of patients who present persistent smell disorders after resolution from Covid-19 and negative swab for 4 months at least.
