Reevaluating Order Effects in the Binaural Bithermal Caloric Test.

Conclusions: This experiment demonstrated that while there is great inter-individual and intra-individual variability in caloric test results, the order of irrigations had no significant effect in the test. Future studies may explore the effects of nonphysiological factors on test results. PMID: 29383375 [PubMed - as supplied by publisher]

Even when concussions are associated with prolonged physical and cognitive sequelae, concussions are typically “invisible” on diagnostic brain imaging, indicating that the neuropathology associated with concussion lies under the detection threshold of routine imaging. However, data from brain structural and functional research imaging studies using diffusion tensor imaging, resting‐state functional magnetic resonance imaging, and brain perfusion imaging indicate that these imaging sequences have a role in identifying concussion‐related neuropathology. These advanced imaging techniques provide insights into ...

Measures of rapid automatized naming (RAN) have been used for over 50  years to capture vision-based aspects of cognition. The Mobile Universal Lexicon Evaluation System (MULES) is a test of rapid picture naming under investigation for detection of concussion and other neurological disorders. MULES was designed as a series of 54 grouped color photographs (fruits, ra ndom objects, animals) that integrates saccades, color perception and contextual object identification. Recent changes to the MULES test have been made to improve ease of use on the athletic sidelines.

In this study, previously reported head impact data recorded in the field from high school and collegiate football players were analyzed using two finite element head models (FEHM). Forty-five impacts associated with immediately diagnosed concussion were simulated along with 532 control impacts without identified concussion obtained from the same players. For each simulation, intracranial response measures (max principal strain, strain rate, von Mises stress, and pressure) were obtained for the whole brain and within four regions of interest (ROI; cerebrum, cerebellum, brain stem, corpus callosum). All response measures we...

AbstractPurpose of ReviewThe goal of this review article is to examine policies for return to learning (RTL), and how RTL intersects with best practices and special education laws and regulations.Recent FindingsConcussion is a well-documented public health concern. Much research has been dedicated to return to play. However, recent focus has been geared towards RTL, as some evidence suggests that cognitive difficulties may linger somewhat longer than physical symptoms. While most concussions resolve quickly, some children are at higher risk for persistent symptoms (usually those with some additional concern such as depress...
