Rugby link to dementia investigated
A NEW Zealand Herald investigation has found that five men from a single Ranfurly Shield-winning rugby team have been diagnosed with dementia. Their families attribute their conditions to concussions suffered during their playing days.
The Herald has discovered a cluster of dementia cases among the successful Taranaki shield side of 1964.
The odds of that occurring could be as high as three in 100,000, which medical experts believe adds to growing anecdotal evidence that multiple concussions suffered in rugby can lead to serious brain diseases later in life.
There have been no claims lodged with the Accident Compensation Corporation, but a spokeswoman acknowledged that with greater understanding and awareness of the dangers of concussion it is likely "that we will in the future".
The Herald has spoken to families of four players affected by dementia, mainly Alzheimer's. We have also identified at least one other player of that era afflicted by the disease but do not have permission to identify him.
All the named players suffered serious concussions during their playing days, with Neil Wolfe admitting he only "woke up" during halftime of his debut test against France at Eden Park in 1961, after being knocked out in a late "coat-hanger tackle" after 20 minutes.
That was one of three serious concussions he endured during his fleet-footed career.
The other players in that Taranaki backline who have died or are dying with dementia are Ross Brown, arguably Taranaki's greatest player, who passed away after a long battle with Alzheimer's in 2014; Bob O'Dowda who is now in permanent care in New Plymouth; and Kerry Hurley, who is cared for in a home in Christchurch.
The link between dementia and head trauma like that suffered by rugby players is a potential powderkeg for rugby administrators.
Recent studies, particularly in the United States, have established persuasive links between repeated head trauma, such as concussion and the early onset of cognitive issues such Chronic Traumatic Encephalopathy (CTE), which was once known as being punch drunk.
A recent study of retired French rugby players reported a "significantly greater number of concussions and recurrent concussions than other retired sportsmen". It also found that retired rugby players with recurrent concussions were more likely to suffer from major depressive disorders.
However, a 2015 Auckland University of Technology study, carried out in conjunction with New Zealand and World Rugby, concluded that ex-sportsmen, irrespective of concussions incurred, suffered no negative occurrences beyond the norm in terms of marital status, mental health issues or brain-cell efficiency. There were findings that ex-sportsmen with four or more concussions performed worse in some neuropsychological and balance tests, but those findings were not definitive.
In terms of the 'Taranaki curse', Professor Thomas Lumley, a biostatistician at Auckland University, said the chances of five players in a single team developing the condition before age 70 was about 3 in 100,000. The chances of dementia increased the more elderly the players became.
The difficulty is in differentiating between when the men started showing symptoms of dementia and when they were officially diagnosed. "You could find dementia/Alzheimer's in four or five players in the same team of this age just by bad luck, but the chance is low enough to reinforce existing concerns about the effects of concussion in rugby," Lumley said.
Jan O'Dowda, the wife of Bob, said her husband's diagnosis was difficult to deal with, as was his precipitous decline. The more people she talked to, the more startling the information was.
"I was trying to establish why he would have got dementia at such a young age and why it would have developed so rapidly," she said. "Some of his mates told he took some serious head knocks quite early in his playing career."
Since then, O'Dowda has been left astonished by how many times her husband's story is mirrored by former teammates.
There is the unpalatable prospect that what is happening in Taranaki now is happening elsewhere, and many believe it could get worse before it gets better.
Rugby turned professional in 1996 but the sport's rulers did not start getting smart about concussion until about five years ago. Even now New Zealand Rugby Players' Association chief Rob Nichol says there is too big a discrepancy between various rugby environments in their attitude towards concussion.
"For the past four or five years, we've just assumed there is a connection," Nichol said. "Our starting point is if there is brain trauma and it's not correctly managed, there will be complications later in life. We don't need a scientist or anyone to tell us that; we're just assuming it.
"We're pushing as hard as we can to make sure we're at the forefront globally in concussion management."
