Do brain activation changes persist in athletes with a history of multiple concussions who are asymptomatic?
To evaluate brain activation patterns of asymptomatic athletes with a history of two or more concussions. ⋯ Following the complete resolution of symptoms, a history of two or more concussions is not associated with changes in regional brain activation during the performance of working memory task. Compensatory brain activation may only persist during the typically brief time athletes experience symptoms following concussion.

Measuring brain electrical activity to track recovery from sport-related concussion.
To follow recovery from concussion in a sample of athletes using an electroencephalographic (EEG) index of quantitative brain activity developed previously on an independent Emergency Department (ED) sample of head-injured subjects with traumatic brain injury. ⋯ This study demonstrated that an algorithm of brain electrical activity developed on an independent sample of ED subjects with head injury is sensitive to the effects of sport-related concussion. Using this algorithm, abnormal features of brain electrical activity were detected in athletes with concussion at the time of injury and persisted beyond the point of recovery on clinical measures.

Haemostatic and cranial computed tomography characteristics in patients with acute and delayed coagulopathy after isolated traumatic brain injury.
To investigate whether the development of coagulopathy at different stages after isolated traumatic brain injury (TBI) is associated with distinct cranial computed tomography characteristics. ⋯ Not only the mere presence of coagulopathy, but also the course of haemostatic alterations following neurotrauma may hold predictive value for patient outcome, irrespective of the severity level of cerebral injury.

Comparative StudyComparison of long-term outcomes of patients with severe traumatic or hypoxic brain injuries treated with intrathecal baclofen therapy for dysautonomia.
To compare the long-term outcome of patients with severe traumatic brain injury and patients with hypoxic brain injury with dysautonomia and hypertonia treated with intrathecal baclofen therapy. ⋯ At long-term follow-up, patients with hypoxic brain injury had a poorer functional outcome than patients with traumatic brain injury with persistent symptoms of dysautonomia associated with uncontrolled hypertonia, despite the use of intrathecal baclofen.

Prognosis analysis and risk factors related to progressive intracranial haemorrhage in patients with acute traumatic brain injury.
Since progressive intracranial haemorrhage (PIH) was introduced in neurosurgical literatures, several studies have been performed. PIH has been shown to be associated with a high increase in the risk of clinical worsening and related to morbidity and mortality as well. So, early detection and prediction of PIH is practically important in a clinical situation. ⋯ For patients with the initial CT scan showing subarachnoid haemorrhage, brain contusion and primary haematoma with abnormal D-D levels, an earlier and dynamic CT scan should be performed, for the detection of PIH as early as possible and the medical intervention would be enforced in time.
