78 Dr Christie gave this evidence in these proceedings in relation to the consequences of delay:
The question as to whether you can attribute any long term problems to a delay in treatment I think is a very difficult one. There are some problems that were identified that I didn't actually identify at the time - loss of sense of smell and so forth - which are just completely due to the original injury. He had problems with pain in his shoulder, and although I didn't refer to it, the rehabilitation specialist referred to it. I really can't explain what that's due to. I can't really attribute that particular symptom to some sort of delay in treatment. If there were problems identified by a neuropsychologist in terms of information processing, language processing, that sort of thing, and if someone in a detailed examination did identify some difficulties with fine motor function of his right side as a long term sequelae and that was objectively identified, then you could say that earlier evacuation of the clot may have - may have - led to a better outcome on that side. And that's about as strongly as I can put it either way.
79 The plaintiff relies principally on the evidence of Dr Noel Dan, Neurosurgeon. It October 2004 he concluded:
"Had Mr Neal been taken to hospital rather than to detention it is likely that the extra dural haematoma would have been diagnosed sooner. It is, therefore, also likely that the effects of the head injury would have been significantly better than it was after the delay between his being found at the sight of the assault and his transfer to hospital. The components of the head injury which are likely to have been different are the effects due to compression of the left hemisphere. These would principally include the right hemiparesis. Some memory defect is likely to occur after even a minor head injury and it is difficult to postulate that a major difference in his memory deficit would have been present had the lesion been treated sooner."
80 In his report dated 7 November 2006 Dr Dan added that the re-accumulation of the haematoma did contribute to the bad outcome. He said:
"The eventual outcome is a combination of the volume of the haematoma and the time during which the compression occurs. The first haematoma was larger and the re-accumulation was present for a longer interval of time. It is factual to report that the variability between outcomes is so wide that no one can project with certainty the outcome of evacuating the haematoma in any individual. It is also true that in the broad generality the earlier the haematoma is evacuated the better the probable outcome will be. One of the most significant advances in the management of acute head injury has been the emphasis on early evacuation of the haematoma. For those reasons I believe it is probable, on balance, the first and larger haematoma did contribute to the persistence of the right hemiparesis although re-accumulation may also have done so."
81 Dr Dan gave evidence in these proceedings. He remained of the view that the delay had contributed to some of the plaintiff's ongoing disabilities. He said:
