Simple ‘sniff test’ reliably predicts recovery of severely brain injured patients

A simple smell test could help doctors to identify which patients in a vegetative state will recover. 100% of patients in a vegetative state who reacted to the sniff test went on to regain consciousness. 91% of those were still alive three years post-injury.

How could Covid-19 and the body’s immune response affect the brain?

Mounting evidence suggests coronavirus affects the brain, in addition to the lungs. Researchers are examining the threat COVID-19 posses to long term brain health. They speculate maternal inflammation could lead to an increased risk of autism-like behaviors and neurodevelopment deficits in children born to mothers diagnosed with coronavirus. Other studies are exploring how the virus may spread in the nervous system via synaptic transmission.

Kisspeptin hormone injection can boost brain activity associated with attraction

A shot of the reproductive hormone kisspeptin enhances brain activity in response to olfactory and visual cues of attraction in men. The findings reveal a previously undescribed attraction pathway in humans activated by the hormone and identify kisspeptin signaling as a potential therapeutic pathway for psychosexual and reproductive disorders.

Intranasal stem cell therapy restores smell in mice

The sense of smell has been restored to mice suffering olfactory problems with the aid of stem cell therapies. The findings provide the basis for transitional research to see whether intranasal stem cell treatments can be beneficial for those who have lost their sense of smell.
