Concussion-Mild Traumatic Brain Injury: Recoverable Injury with Potential for Serious Sequelae

Joshua Kamins et al. Neurosurg Clin N Am. 2016 Oct.

Abstract

Concussion is increasingly recognized as a major public health issue. Most patients will return to baseline and experience full recovery, although a subset experiences persistent symptoms. Newer animal models and imaging studies are beginning to demonstrate that metabolic and neurovascular resolution may actually take longer than symptomatic recovery. Repeat traumatic brain injury within the metabolic window of dysfunction may result in worsened symptoms and prolonged recovery. The true risk for second impact syndrome appears to be small, and development of cerebral edema after a mild impact may be related to genetic risks rather than serial impacts.

Keywords: Concussion; Mild TBI; Sequalae of concussion.
