Bicycle accident deaths on the rise

In Florida and nationwide, the number of deaths in bicycle accidents is rising. Advocates say bicycle safety needs to be improved.

According to a new report by the Governors Highway Safety Association, the number of bicycle fatalities rose by 16 percent between 2010 and 2012. There were 621 bicycle deaths in 2010, 680 in 2011 and 722 in 2012.

The authors of the association’s report said that the increase in fatalities does not necessarily mean that bicycling is becoming more dangerous. It is more likely that the change is occurring because bicycling is simply becoming more popular. As more people use bicycles, the raw number of deaths has increased. It is difficult to measure whether bicycling is also becoming more dangerous in comparison, because there are no national statistics kept on the popularity of riding bicycles.

Still, bike safety advocates agree that even one death is too many, and that changes, like better bike lanes, are needed.

The problem is particularly severe in Florida. In Florida, 120 bicyclists were killed in 2012. Both in terms of raw numbers and as a percentage of the population, Florida has ranked as the deadliest state for bicycle riders in the country for many years. The state’s death rate for bicycle riders is three times higher than the national rate, and Tampa and Orlando are consistently ranked as the nation’s deadliest metropolitan areas for bicyclists.

Study finds traumatic brain injury can accelerate atrophy of the brain

Traumatic brain injury (TBI) can accelerate the rate of brain atrophy, according to a new study published in the Annals of Neurology. According to the study, the brains of patients with TBI were estimated to be older than their actual chronological age. The study examined patients who had suffered brain injuries from car accidents, falls, sports injuries and assaults.

The study used neuroimaging of the brain, which has been accepted as a method of estimating the age of healthy individuals. The researchers compared 99 patients with TBI and persistent neurological problems to 113 healthy people. Eighty-three percent of the TBI patients had moderate to severe brain injuries and 17 percent had mild injuries.

The study found that the neuroimaging model was able to predict the age of the healthy individuals with a high degree of accuracy. However, the model predicted TBI patients to be older than they actually were, and the degree of the discrepancy was correlated with the severity of their injuries.

The researchers concluded that TBI may trigger ongoing neurodegenerative processes that lead to progressive atrophy and hasten the brain’s aging process, though brain atrophy was only significant in TBI patients with moderate to severe brain injuries.
