Brain injuries 'can cause loss of taste and smell'RSS Feed
People who experience a brain injury can find that their sense of smell or taste has been lost, a new study has found.
Mild to severe traumatic brain injury could cause olfactory loss, according to the research published in the journal Brain Injury.
"We also found that patients with a frontal lesion were more likely to show olfactory dysfunctions," said study co-author and neuropsychologist Maurice Ptito, a professor at the Universite de Montreal School of Optometry.
The scientists studied 49 people with traumatic brain injuries and discovered that more than half (55 per cent) of them had an impaired sense of smell, while 41 per cent of participants were unaware of their olfactory deficit.
It was carried out by Professor Ptito together with Audrey Fortin, associate professor at the Universite de Montreal School of Optometry, and Mathilde Beaulieu Lefebvre, of the Department of Psychology.
Earlier this month, an especially unusual symptom following a brain injury was reported: Tom Paterson, 39, from Largs in Ayrshire, awoke from a coma to find himself speaking with a foreign accent.
