Reorganizing brain structure through olfactory training in post-traumatic smell impairment: An MRI study

Post-traumatic olfactory dysfunction (PTOD), mostly caused by head injury, is thought to be associated with changes in the structure and function of the brain olfactory processing areas. Training and repeated exposure to odorants lead to enhanced olfactory capability. This study investigated the effects of a 16-weeks olfactory training (OT) on olfactory function and brain structure.Twenty-five patients with PTOD were randomly divided in three...
