Anosmia remains a relatively unknown problem, due primarily to a lack of data or studies thoroughly examining the issue. That said, those affected by it know it’s an incredibly frustrating condition. So, what conditions can cause anosmia?
1. Brain Trauma
Our understanding of brain trauma—whether caused by sports injuries, automotive accidents, or something else— continues to build. For those who suffer from a significant brain injury, the symptoms are many and often last for years after the event.
One of these symptoms can be anosmia. Injury to the brain often causes smell loss, which can last for a short or longer period of time. Specifically, damage to the brain’s frontal lobe, where smell is processed. Direct injury to the nose can also cause loss of smell, though this issue typically resolves itself faster than a brain injury.
