Prevention of concussions
Prevention of mild traumatic brain injury involves taking general measures to prevent traumatic brain injury, such as wearing seat belts and using airbags in cars. Older people are encouraged to try to prevent falls, for example by keeping floors free of clutter and wearing thin, flat, shoes with hard soles that do not interfere with balance.
Traumatic memories
Neuroscience has shown that memories are vulnerable to disruption for several hours after they form. Holmes and colleagues proposed that because of this visuospatial distractors like Tetris, if administered within six hours of a traumatic event could help prevent symptoms of flashbacks. Also there is some evidence that memories can become vulnerable to disruption even at longer periods of time in a process known as reconsolidation.
