Low levels of blast raises intracranial pressure and impairs cognitive function in rats

Journal of Neurotrauma, 2009
Brain injury after high-level blast has been established both clinically and experimentally. Less is known about the effects on the brain of exposure to low to moderate blast levels, such as those encountered by military personnel during the firing of weapons.

Low-Level Blast Exposure in Humans A Systematic Review of Acute and Chronic Effects

Journal of Special Operations Medicine, 2020
There is growing concern that military breaching and training and firing artillery and mortars, grenades, and shoulder-fired weapons may have some type of cumulative deleterious effects. There are anecdotal reports of those with repetitive exposure to low-level blast complaining of various symptoms, as well as increasing empirical evidence. The purpose

Mild Traumatic Brain Injury From Repeated Low-Level Blast Exposures

Volume 3: Biomedical and Biotechnology Engineering, 2015
Recent studies on military breachers in training environments suggest that there are neurocognitive risks from exposure to repeated low-level blasts. However, the dose accumulation effects from multiple low-level blast exposures and their relation to mild traumatic brain injury (mTBI) are not well understood.

The Effects of Low-level Repetitive Blasts on Neuropsychological Functioning

2015
Abstract : Despite increased research on blast-related mild traumatic brain injury (mTBI), relatively little is understood about long-term symptomatology. The primary objective of this study was to determine whether repeated exposure to low-level controlled blasts produces observable changes in cognitive functioning and psychological health. The target

Development of a Portable Tool for Screening Neuromotor Sequelae From Repetitive Low-Level Blast Exposure

Military Medicine, 2017
Blast exposure is a prevalent cause of mild traumatic brain injury (mTBI) in military personnel in combat. However, it is more common for a service member to be exposed to a low-level blast (LLB) that does not result in a clinically diagnosable mTBI. Recent research suggests that repetitive LLB exposure can result in symptomology similar to symptoms ...

Laminated Glass Curtain Walls and Laminated Glass Lites Subjected to Low-Level Blast Loading

Journal of Structural Engineering, 2008
Linear elastic and nonlinear elastic analytical investigations are reported for a nearly conventional, laminated glass curtain wall with split screw spline mullions subjected to low-level blast loading. Responses dynamic stresses, deflections, and accelerations of the rectangular glass lites within the curtain wall are compared to those of identical ...

Cumulative Blast Impulse Is Predictive for Changes in Chronic Neurobehavioral Symptoms Following Low Level Blast Exposure during Military Training

Military Medicine
ABSTRACT Introduction Cumulative low-level blast exposure during military training may be a significant occupational hazard, increasing the risk of poor long-term outcomes in brain function. US Public Law 116-92 section 717 mandates that US Department of Defense agencies document the blast exposure of

Structures Subjected to Low-Level Blast Loads: Analysis of Aerodynamic Damping and Fluid-Structure Interaction

Journal of Structural Engineering, 2012
AbstractThis paper presents the structural behavior of idealized linear single-degree-of-freedom systems subjected to weak blast loads. The authors derive a new coupling model taking into account fluid-structure interaction (FSI) and aerodynamic damping resulting from the surrounding air. This model contributes to a better understanding of the physical

Low-Level Blast Raises Intracranial Pressure and Impairs Cognitive Function in Rats: Prophylaxis with Processed Cereal Feed

Journal of Neurotrauma, 2010
There is increasing evidence that even low levels of blast cause brain injury, but little is known about their thresholds and mechanisms. Exposure of rats to 10-60 kPa blasts elevate intracranial pressure (ICP) in a dose-dependent manner and impair cognitive function. We have evaluated a prophylactic measure against these brain injuries in a rat animal

Impact of Low-Level Blast Exposure From Military Training and Career Cumulation on Hearing Outcomes

Military Medicine
ABSTRACT Introduction Occupational trades expose military service members to unique sound exposure profiles, distinct in frequency and amplitude to those commonly studied in industrial settings. Characteristics of the energy exposure incurred through blast exposure exercises a distinct mechanism of ...
