Brain injury 'can cause taste and smell disorders'RSS Feed

People who suffer brain injuries can experience neurological damage that might lead them to lose their sense of taste and smell, it is reported.

Neurological disorders caused by conditions such as Parkinson's and Alzheimer's can cause long-lasting damage to the "intricate neural network" that processes the two senses, according to enotes.com.

The website states: "20 to 30 per cent of head trauma patients suffer some degree of smell disorder, which can in turn affect taste."

It goes on to point out that exposure to environmental toxins such as lead and mercury can "severely hinder" the ability to smell and taste, due to damage to taste buds and sensory cells in the nose or brain.

Ageing itself is also associated with a diminished sense of taste and smell sensitivity, the website adds.

Meanwhile, wowktv.com has reported that a seminar was held at West Virginia University to discuss issues surrounding the fact that a traumatic brain injury can occasionally cause a change in a patient's personality.
