“The study clearly shows that olfactory deficits may occur in mild traumatic brain injury, and moderate and severe head trauma patients,” said study co-author and neuropsychologist Maurice Ptito, a professor in the School of University of Montreal optometry. “We also found that patients with frontal lesions were more likely to olfactory dysfunction.
The research team recruited 49 people with traumatic brain injury (73 percent of men with a mean age of 43) who completed a questionnaire and underwent two tests to measure the loss of smell the smell. The result: 55 percent of subjects had an impaired sense of smell, while 41 percent of the participants were aware of their olfactory deficit.
