Will the Tory right revolt over Lisbon?

Can Cameron avoid another civil war over Europe?

"When the facts change, I change my mind. What do you do, sir?" So ran John Maynard Keynes's celebrated riposte. It is essentially this defence that David Cameron will employ when he breaks his pledge to hold a referendum on the Lisbon Treaty.

He will argue that his promise was made at a time when the treaty was unratified. He will point out that he never promised a retrospective referendum. But it was still foolish of him to use the formulation "cast-iron guarantee" when promising a referendum to Sun readers back in 2007.

The arch-Eurosceptic Bill Cash articulated the thoughts of many on the right of the party when he said:

We need a full referendum on Lisbon as we were promised and as we voted in the House of Commons. No ifs or buts. This is about the government of the United Kingdom operating in line with the democratic wishes of the electorate.

Cameron should be able to ride out grass-roots discontent over Lisbon provided it doesn't spread to the shadow cabinet. In a fascinating column on Sunday, Peter Oborne identified William Hague as the man most likely to take on the Tory leader over Europe. He wrote:

Intellectually formidable, he is a very live alternative prime minister. More dangerously still, he no longer yearns for power and was only persuaded to return to front-line politics with difficulty. There is very little to stop Hague from resigning and, were he to do so, he could scarcely avoid becoming a very powerful focus of resistance to a Cameron premiership.

I would be surprised to see anything but resolute discipline before the next election; the Conservatives can't wait to get their hands back on those red boxes. But should Cameron fail to repatriate economic and social powers once in office, we could see another civil war over Europe.

ConservativeHome's Tim Montgomerie writes: "If Britain's relationship with the EU is fundamentally the same after five years of Conservative government, the internal divisions that ended the last Tory period in government will look like a tea party in comparison."

This may look like a piece of dispassionate analysis but it is also a clear threat. Those such as Montgomerie who favour EU withdrawal will maintain their pragmatic support for Cameron's stance only for so long.

Tetris and sleep deprivation: how we can help emergency workers cope with trauma

First responders are at serious risk of developing PTSD during events like the Paris attacks. 

Some people seem able to deal with anything. They save a stranger from bleeding out in a bombed restaurant, protect passers-by from heavily armed gunmen, pull dead and dying people out of collapsed buildings, and they keep going because it is their job. These people are first responders.

When trauma goes on for days, as it has recently in Paris, however, the odds of them bouncing back from the violence, death and injury they are witnessing rapidly diminishes. They are at greater risk of developing a severe stress reaction known as post-traumatic stress disorder (PTSD). One study found that the worldwide rate of PTSD among first responders is 10 per cent, much higher than the 3.5 per cent rate among those not involved in rescue work.

Tetris to the rescue

So how best to address the problem? Research is in its infancy, but there are some promising studies. Emily Holmes’ group at the University of Cambridge has been looking at the benefits of playing Tetris, a video game, after a traumatic experience. The idea is that this could block the consolidation of traumatic memories so they don’t “flash back” later on.

For the study, her team first traumatised people by showing them distressing footage from public safety videos. The next day they invited them back into the lab to reactivate the memories with still images taken from the videos. One group then played Tetris for 12 minutes while the other sat quietly. Over the following week, the group who played Tetris had about 50 per cent fewer unwanted memories from the films compared to the group who didn’t.

The team concluded that playing Tetris helped individuals because it soaks up their visual processing capacity, making it harder for the brain to consolidate the visual parts of a traumatic memory.

Since it takes about six hours for the brain to cement a memory, the key is to play the game soon after trauma or within six hours of re-activating the traumatic memory. How long the helpful effects of playing Tetris will last and whether it will translate into helping people after real-life trauma is still unknown.

Talking it through

Other techniques, such as “updating”, taken from a highly-effective talking treatment for PTSD, may be more practical and easier to implement.

Like a detective, updating is a technique that focuses on finding new information and linking it to the case, the past memory. This is necessary because when the brain and body are in survival mode during trauma, the mind finds it difficult to encode all the relevant facts. Often key pieces of information that could make the memory less traumatic are lost. Updating links new information to someone’s memory of their trauma to make it less upsetting.

But can updating help to reduce unwanted memories after trauma?

We carried out a study, published in PLOS ONE, in which we traumatised people by showing them terrifying films of humans and animals in distress. We then divided our participants into three groups. One group watched the films again but were given new information about how long people suffered and whether or not they lived or died – essentially, they were updated. The second group watched the same films again but without the new information. And the third group watched films of humans and animals who were not in distress. The updated group had fewer traumatic memories and PTSD symptoms than the other two groups.

Updating is now being used by some UK emergency services. First responders will gather after critical incidents and update their memories of what happened before they go home.

Sleep deprivation

There are other techniques that may be helpful. One study found that depriving people of sleep may be useful in the aftermath of trauma.

But the same study found that a week after the trauma, people who had been deprived of sleep had the same number of unwanted memories as people who had slept well afterwards. Consequently, it remains unclear whether there would be any long-lasting benefits using this method. There are, however, certainly health risks linked to lack of sleep.

Still looking for a solution

To develop preventative interventions, we need to study newly-recruited emergency workers who haven’t yet suffered on-the-job trauma and follow them over time, spotting which “coping styles”, present before trauma, may predict their reactions afterwards.

For example, some people naturally react to stressful life events by dwelling on them, thinking about why they happened for hours on end. This strategy, called rumination, has been linked to PTSD in people who survived car crashes.

If rumination predicts PTSD in first responders, then preventative interventions could train people to spot when they are dwelling on an event and refocus their attention to the task at hand.

When we have identified which factors heighten emergency workers’ risk of developing PTSD, programmes can be developed to target those vulnerabilities. Only then can an intervention, directed at first responders most at risk of developing PTSD, properly protect them in their line of work.
