Abnormal corticospinal excitability in traumatic diffuse axonal brain injury.
This study aimed to investigate the cortical motor excitability characteristics in diffuse axonal injury (DAI) due to severe traumatic brain injury (TBI). A variety of excitatory and inhibitory transcranial magnetic stimulation (TMS) paradigms were applied to primary motor cortices of 17 patients and 11 healthy controls. The parameters of testing included resting motor threshold (MT), motor evo...
متن کاملCorticospinal excitability in patients with anoxic, traumatic, and non-traumatic diffuse brain injury.
BACKGROUND Transcranial magnetic stimulation (TMS) have been frequently used to explore changes in motor cortex excitability in stroke and traumatic brain injury, while the extent of motor cortex reorganization in patients with diffuse non-traumatic brain injury remains largely unknown. OBJECTIVE/HYPOTHESIS It was hypothesized that the motor cortex excitability would be decreased and would co...
متن کاملmental trauma experienced by caregivers of patients with diffuse axonal injury or severe traumatic brain injury
conclusions a long-term longitudinal study encompassing integrated research is needed to fully understand the traumatic experiences of caregivers. unless research on tbi or dai trauma is given its proper attention, the burden of trauma and injury on societies will continue to exacerbate globally. context as with care giving and rehabilitation in chronic illnesses, the concern with traumatic bra...
متن کاملTraumatic Brain Injury at Multiple Length Scales: Relating Diffuse Axonal Injury to Discrete Axonal Impairment
The length scales involved in the development of diffuse axonal injury, typically range from the head level (i.e., mechanical loading) to the cellular level, where discrete axonal injuries are located near inclusions. The aim is to investigate the local axonal strains near an inclusion in relation to the tissue level strains of the brain stem during mechanical loading of the head and the result...
متن کاملProton MR spectroscopic imaging depicts diffuse axonal injury in children with traumatic brain injury.
BACKGROUND AND PURPOSE Diffuse axonal injury (DAI) after traumatic brain injury (TBI) is important in patient assessment and prognosis, yet they are underestimated with conventional imaging techniques. We used MR spectroscopic imaging (MRSI) to detect DAI and determine whether metabolite ratios are accurate in predicting long-term outcomes and to examine regional differences in injury between c...
