128 As I have noted, Professor McFarlane interviewed the plaintiff in January 2003. Following this, in a report dated 28 January 2003, Professor McFarlane concluded:
"On the basis of the history obtained, it is my view that Mr Brittain continued to suffer some symptoms of a post-traumatic stress disorder, but did not currently satisfy the diagnostic criteria. In expressing my opinion, I am limited by the fact that I have not seen a number of the relevant documents, particularly referred to in Dr Champion's first report concerning the disciplinary actions brought against him in the Navy. His current situation is dominated by anxiety symptoms, specifically relating to his impending legal action. This litigation setting does not appear to have led to a specific exacerbation of his post-traumatic symptoms. The symptoms which he clearly described in the past were nightmares relating to the HMAS Melbourne/Voyager disaster and also distressing recollections of the event. His first interview with Dr Champion indicates his psychological distress associated with the recollection of the experience. It appears that with the treatment provided that this distress has decreased significantly. He demonstrated no such emotional disequilibrium at the time of his interview with me.
…
Mr Brittain currently has few intrusive symptoms. He similarly, has few avoidance phenomenon and these appear to be intermittent, in contrast to his attempts to avoid recollections about the disaster. In recent years an example was his initial ability to tolerate part of the film The Titanic, but then needing to leave. He has ongoing startle response. It is difficult to judge the degree of his sleep disturbance in latter years because of his nocturnal frequency due to his enlarged prostate. However, it does appear to be an issue. He does not appear to have any particular symptoms of hyper vigilance. He stated his concentration was problematical. His irritability is an ongoing issue. However, he did not appear to be particularly socially withdrawn and had a continued sense of pleasure. He did not appear to have any emotional numbing.
Against this background, my report appears to differ from that of Professor Beverly Raphael's in terms of the severity and clinical significance of some of his symptoms. Similarly, the report of Dr Holwill provided a similar history, particularly of the issues of insomnia, nightmares, chronic mild depression and avoidance of thoughts and feelings of the event. Given that I did not examine him at this time, I believe that my report is consistent with that of Dr Holwill and Dr Raphael."
129 The principal challenge that the defendant makes to the acceptance of the opinions of Dr Holwill, Professor Raphael and Professor McFarlane is that they necessarily depend upon the accuracy of the plaintiff's history and report of symptoms. Both are in issue.
130 Dr Holwill and Professor Raphael both consider that the plaintiff's history of sleep difficulty in the period since the collision supports the diagnosis of PTSD. Dr Holwill obtained a history of sleep disturbance with initial, middle and late insomnia every night. He noted that this had been contributed to by prostate difficulties. Dr Holwill did not obtain a more detailed account of the onset of the insomnia.
