The College had asked about this in Question 28from the second paper of 2011.
Specifically, they wanted the risk factors for post-traumatic seizures.
The best resource for such things is the Brain Trauma Organisation Guidelines for Management Traumatic Brain Injury. In fact, the College examiners pillage their guidelines liberally, cutting and pasting whole blocks of text into the model answers.
The below-linked review article on post-traumatic seizure prophylaxis presents an even more extensive table, which is perhaps more than is expected of a 2-mark SAQ answer.
It is reproduced below, more for completeness than educational value.

A good 2013 review article is available for the time-rich exam candidate to scrutinise.
