SHAFAQNA (Shia International News Association) — Why do some
people seem to suffer no consequences from a concussion while
others have symptoms as severe as personality change? A new type
of brain scan helps explain why, and could help doctors and
patients determine the likely outcomes of a concussion. The new
technique analyzes data from brain imaging studies, according to
the study published in the journal Brain Imaging and Behavior
today. Concussion victims have unique spatial patterns of brain
abnormalities that change over time, researchers found, which
could help predict which head injuries are likely to have long-
lasting neurological consequences. Earlier studies identified
differences in patients with concussions and those without, but
the new technique takes the additional step of parsing out the
differences in patients who have concussions. "In fact, most
researchers have assumed that all people with concussions have
abnormalities in the same brain regions," said Dr. Michael
Lipton, the study's lead
