First- and second-order contrast sensitivity functions reveal disrupted visual processing following mild traumatic brain injury

Vision is disrupted by traumatic brain injury (TBI), with vision-related complaints being amongst the most common in this population. Based on the neural responses of early visual cortical areas, injury to the visual cortex would be predicted to affect both 1(st) order and 2(nd) order contrast sensitivity functions (CSFs)-the height and/or the cut-off of the CSF are expected to be affected by T...

Cerebrovascular pathophysiology following mild traumatic brain injury.

Mild traumatic brain injury (mTBI) or sport-induced concussion has recently become a prominent concern not only in the athletic setting (i.e. sports venue) but also in the general population. The majority of research to date has aimed at understanding the neurological and neuropsychological outcomes of injury as well as return-to-play guidelines. Remaining relatively unexamined has been the pat...

Comparison of visual perception error among patients with mild traumatic brain injury with healthy people

Background: Mild traumatic brain injury (MTBI) is the least brain injury due to direct or indirect blow to the head, which according to the Glasgow scale is given a score between 13 and 15. The findings indicate cognitive impairment. Perceptual dysfunction is one of the most important cognitive deficits in these patients. The present study was designed and performed to compare MTBI patients wit...

Predicting Mild Traumatic Brain Injury with Injury Risk Functions

To assess the safety of various products, equipment, and vehicles during traumatic events injury risk curves have been developed correlate measurable parameters with risk of injury. The first risk curves to predict head injuries focused on severe head injuries such as skull fractures. These curves were generated by impacting cadaver heads. To understand the biomechanics of mild traumatic brain ...
