College Answer

A structure approached works well for “describe the factors …” questions. Better answers 
provided a definition of ICP, explained the Monro-Kellie doctrine and then detailed the factors 
which affect the volume of each of the components - cerebro spinal fluid (CSF), cerebral blood 
flow and brain parenchyma. Some candidates focused only on factors which cause intracranial 
hypertension and were thus unable to score full marks. Many candidates stated that CSF 
production was ICP dependant which is incorrect.
