Olfactory Training and Visual Stimulation Assisted by a Web Application for Patients With Persistent Olfactory Dysfunction After SARS-CoV-2 Infection: Observational Study.

Background: Persistent olfactory dysfunction is a significant complication of SARS-CoV-2 infection. Olfactory training involving aromatic oils has been recommended to improve olfactory recovery, but quantitative data are missing.

Objective: We aimed to quantify the benefit of olfactory training and visual stimulation assisted by a dedicated web application for patients who experienced olfactory dysfunction for ≥1 month.

Clinical and electroencephalographic abnormalities during the full duration of a sporadic hemiplegic migraine attack.

Electroencephalographic (EEG) abnormalities have been reported during migraine attacks but their spatial and temporal distributions are not well known. We report the temporospatial dynamics of EEG during the full duration of a migraine attack with aura in a 19-year-old woman. She experienced episodes of hemiplegic migraine since the age of 2.
