Smell Tests May Predict Anxiety And Depression After A Concussion

Patients with smell problems after a concussion are at risk to develop anxiety and depression. Smell testing right after a concussion may predict these mood disorders.

Anxiety and depression are amongst the most important long-term consequences of concussions. We examined whether individuals who exhibited smell problems after a concussion had a higher risk to develop symptoms of anxiety and depression. We tested two cohorts within 24h and within 4 weeks after a concussion and followed up with them. Patients with smell problems at baseline had more symptoms of depression and anxiety at follow up after 1 year and 6 months, respectively. Smell tests are easy to carry out and may help to predict mood disorders and guide clinicians to early therapeutic interventions.
