Noninvasive Brain Stim Promising for COVID-Related Smell Loss

Noninvasive brain stimulation may help restore a sense of smell in patients with chronic anosmia or hyposmia related to COVID-19, early research suggests. Results of a small, double-blind, sham-controlled study showed anodal transcranial direct current stimulation (A-tDCS) combined with olfactory training (OT) provided notable and durable improvement in seven patients with persistent COVID-19-related hyposmia or … Read more

Long-Term Smell Loss in COVID-19 Tied to Brain Damage

Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center. Patients with COVID-19, especially those with an altered sense of smell, have significantly more axon and microvasculopathy damage in the brain’s olfactory tissue versus non-COVID patients. These new findings from a post-mortem study may explain long-term loss of smell in some … Read more
