My research has found that a third of people who lose consciousness as a result of a concussion, self-report having memory problems.

Age and depression were also found to predict memory problems. An increase in age was shown to result in an increased risk of memory problems, while an increase in depressive symptoms was found to decrease the risk of memory problems.

Findings also showed that younger and higher educated people were at an increased risk of depression. There was some evidence of concussion being related to depression, but further research in this area is needed.

One of the cognitive tests used was negatively affected by concussion which suggests that there may be an effect of concussion on cognition.
