If you’ve had a seizure in the last few days, you’re more likely to be in a coma or vegetative state.
But the brain freeze isn’t limited to those in a comatose state.
Researchers have now discovered that people with a history of brain trauma are more likely than the general population to have brain freeze, a condition that has been dubbed the “brain freeze of the century”.
The findings, from the University of Nottingham, may help scientists understand why certain people have difficulty processing emotions.
The study, which examined brain activity during the freezing of people with epilepsy, was published in the journal Cerebral Cortex.
“Brain freeze is a phenomenon we’ve seen before, and we’re now trying to understand why it happens,” lead author Professor Mark T. O’Donnell said.
“For example, some people experience a mild brain freeze after a seizure.
For other people, the experience is much more severe and they can’t process emotions at all.”
Dr O’Neill said it was a fascinating subject that needed further investigation.
“There are lots of questions that remain unanswered, such as what happens when you’ve just had a brain seizure, what happens to brain activity when someone’s in a vegetative or coma state,” he said.
In the study, Dr O’Connell and his team measured brain activity from patients with epilepsy and those who had a history or diagnosed a brain injury.
The researchers also recorded the electrical activity of the cerebrospinal fluid (CSF), a fluid that surrounds the brain and provides nutrients and oxygen.
This allowed them to look at changes in brain activity and to compare it to a standard brain scan.
“We used a method called diffusion tensor imaging to measure the volume of the CSF in the patients and compared it to the normal brain scan,” Dr O’son said.
He said that after the seizure, the brain was able to regenerate some of its tissue.
“As a result, the volume in the brain recovered and was not significantly different to the healthy brain.”
In contrast, the CSFs volume showed a significant decrease in patients with a brain stroke,” Dr Tod said.
The findings showed that patients with an epilepsy history had an increased likelihood of experiencing brain freeze compared to those who were not diagnosed with epilepsy.”
However, we also found that the rate of brain freeze was not correlated with a specific brain injury history, suggesting that there was no relationship between brain injury and brain freeze,” Dr Tran said.
