Diffuse Axonal Injury at Ultra-High Field MRI
OBJECTIVE Diffuse axonal injury (DAI) is a specific type of traumatic brain injury caused by shearing forces leading to widespread tearing of axons and small vessels. Traumatic microbleeds (TMBs) are regarded as a radiological marker for DAI. This study aims to compare DAI-associated TMBs at 3 Tesla (T) and 7 T susceptibility weighted imaging (SWI) to evaluate possible diagnostic benefits of ul...
متن کاملAbnormal 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 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 کاملBrain activations in errorless and errorful learning in patients with diffuse axonal injury: a functional MRI study.
PRIMARY OBJECTIVE Errorless learning has been reported to be effective in the rehabilitation of patients with impaired cognitive functions following brain injury. This study compared brain activations in errorless learning (EL) and errorful learning (EF) in patients with diffuse axonal injury (DAI) using a functional magnetic resonance imaging (fMRI). METHODS AND PROCEDURES The participants w...
