Although safety standards have reduced fatal head trauma due to single severe head impacts, mild trauma from repeated head exposures may carry risks of long-term chronic changes in the brain's function and structure. To study the physical sensitivities of the brain to mild head impacts, we developed the first dynamic model of the skull-brain based on in vivo MRI data. We showed that the motion ...

Head trauma is being more frequently recognized as a causative agent in balance disorders. Most of the published literature examining traumatic brain injury (TBI) after head trauma has focused on short-term prognostic indicators and neurocognitive disorders. Few data are available to guide those individuals who see patients with balance disorders secondary to TBI. Our group has previously exami...

OBJECTIVE To identify in mild head injured children the major differences between those with a Glasgow Coma Scale (GCS) 15 and GCS 13/14. METHOD Cross-sectional study accomplished through information derived from medical records of mild head injured children presented in the emergency room of a Pediatric Trauma Centre level I, between May 2007 and May 2008. RESULTS 1888 patients were includ...

Traumatic isolated cranial nerve palsies are uncommon and when they do occur, they are usually associated with severe head trauma. Cranial nerve palsy associated with mild head injury is rare. A case is reported of complete left third nerve palsy associated with mild head injury. The rate of recovery for complete third nerve palsy is slow and prolonged. The ptosis recovered in 10 months; the di...

Thirty-five patients and corresponding matched controls were investigated between 5 and 17 months from mild head trauma using the Self Rating Depression Scale and the State-Trait Anxiety Inventory. The findings indicate that compared with an appropriate control group mild head injured patients are at risk of developing depression, whereas their liability to anxiety is not increased. Our results...

Neuropsychological deficits following mild head injury have been reported recently in the literature. The purpose of this study was to investigate this issue with a strict methodological approach. The neuropsychological performance of 50 mildly head injured patients was compared with that of 50 normal controls chosen with the case-control approach. No conclusive evidence was found that mild hea...

A 13-month-old boy presented to our hospital with a history of right hemiparesis and right facial paresis for 2 days. These symptoms occurred several hours after a fall from a bed to the ground. AnMRI of the brain showed an ischemic lesion and cerebral ultrasound examinations demonstrated bilaterally hyperechogenic lenticulostriate arteries (figure). Infantile basal ganglia stroke after mild he...

Head trauma leading to brain injury is an important cause of morbidity and mortality in childhood. Injury severity is related to the mechanism of trauma, which itself varies with age. The vast majority of head trauma in paediatric patients is mild, requires no specific therapy and leaves no sequelae. However, it is important to identify individuals at risk of significant injury, and thus in nee...

traumatic head injury is the underlying cause of approximately 5% of all persons with epilepsy and is the major cause of epilepsies starting in young adulthood. penetrating head injury, particularly among soldiers, carries a risk of almost 50% of developing post-traumatic epilepsy (pte), mostly within 6 months to two years after the trauma. early seizures (within one week of the trauma) are dep...
