Mice don’t malinger: The effects of multiple concussions on the brain

On June 6, 2011, the Boston Bruins were playing the Vancouver Canucks in game 3 of the Stanley Cup finals. Bruins forward Nathan Horton had passed the puck to his teammate Milan Lucic when he was blindsided by the Canucks’s Aaron Rome, who buried his left shoulder into Horton’s face. Horton’s head was spun backwards, down towards the ice. The back of his head was the first part of his body to make contact with the ice. He was knocked unconscious. His arms became rigid. His eyes rolled back in his head. He had a convulsion.

Nathan Horton was concussed.

Concussion is all too common in sports, particularly those, like ice hockey, that involve body-to-body collisions. Yet it’s still somewhat of a medical mystery. Until the last 10 to 15 years, few physicians or scientists considered concussion significant enough to warrant scientific investigation. Thus, we know very little about it.

Brains, babies and battlefields: Taking pediatric neurocritical care to the bedside

From the time he was 11, Robert Tasker knew he wanted to be a doctor. The son of a serviceman, he was drawn to battlefield surgery, evacuations and managing traumatic injuries. Instead, he ended up on a different kind of battlefield, where what’s at stake are the highly vulnerable, still developing brains of infants and children – and where it’s critical to be mobile and show up on time.

Tasker directs the Pediatric NeuroCritical Care program at Children’s Hospital Boston, the first of its kind in the world. His goal is to protect brain function not only in children suffering direct head injury, but children undergoing major surgery, children with stroke, children hospitalized for critical illness, children on ventilators, children with nervous-system infections like meningitis and more.

Treating traumatic brain injury with a nasal spray?

Could an extract from this Chinese club moss have a neuroprotective effect?

Severe traumatic brain injury — such as that associated with military head wounds — is basically untreatable. In addition to cognitive and motor impairments, it leads to epilepsy about 20 to 50 percent of the time; anticonvulsants given after trauma have been tried as a preventative but have not worked. “After head trauma, physicians often watch symptoms evolve, and there’s nothing we can do to prevent them,” says Alexander Rotenberg, a neurologist and neurobiology investigator at Children’s Hospital Boston.

The brain damage begins within seconds of the actual trauma, but a punishing series of biochemical events in the brain unfold over the subsequent days and weeks, making matters worse
