WEDNESDAY, Nov. 20, 2013 (HealthDay News) -- Months after concussion
symptoms such as dizziness, headaches and memory loss fade, the brain
continues to show signs of injury, a new study suggests.
.
Comparing 50 concussion patients with the same number of healthy people,
researchers found that the brains of those suffering concussions showed
abnormalities four months later. This happened despite the fact that their
symptoms had already eased to some degree.
.
The findings may sway conventional thinking about when it's safe to resume
physical activities that could produce another concussion, the study
authors said.
.
"This is a very different population than professional athletes going out
and having concussions on a fairly [frequent] basis, as well as jostling
their brain around their skull on a regular basis in practice," said study
author Andrew Mayer, an associate professor of translational neuroscience
at the Mind Research Network in Albuquerque, N.M. It's hard to predict an
outcome based on these findings, he said, "but just because you feel
you're healed doesn't mean you are."
.
The study, which was funded by the U.S. National Institutes of Health, is
published in the Nov. 20 online edition of the journal Neurology.
.
Considered a mild traumatic brain injury that occurs from a sudden blow to
the head or body, a concussion has symptoms that range from headache and
blurry vision to difficulties in sleeping or thinking clearly. Most occur
without losing consciousness, according to the U.S. Centers for Disease
Control and Prevention.
.
Mayer and his team matched 50 patients with mild concussions to 50 healthy
people of similar age and education levels. They tested all participants
in memory and thinking skills, as well as other symptoms such as anxiety
and depression.
