A debate has ensued about the long-term consequences of mild traumatic brain injury, the 'signature injury' of the Iraq and Afghanistan Wars. Most epidemiological studies have found that mild traumatic brain injury is unrelated to unspecific post-concussion symptoms based on self-reported symptoms. A longitudinal study, in this issue of the Journal, using objective tests has demonstrated that mild traumatic brain injury has limited lasting neuropsychological consequences.

The UK has seen a dramatic increase in alcohol consumption and alcohol-related harm over the past 30 years. Alcohol taxation has long been considered a key method of controlling alcohol-related harm but a combination of factors has recently led to consideration of methods which affect the price of the cheapest alcohol as a means of improved targeting of alcohol control measures to curb the consumption of the heaviest drinkers. Although much of the evidence in favour of setting a minimum price of a unit of alcohol is based on complex econometric models rather than empirical data, all jurisdictions within the UK now intend to make selling alcohol below a set price illegal, which will provide a naturalistic experiment allowing assessment of the impact of minimum pricing.
