Incidence rates of traumatic brain injury are high in both industrialized and non-industrialized countries and have been estimated variously to be between 150–250 cases per 100,000 population per year. The estimated incidence rates for subarachnoid hemorrhage (SAH) are between 10 to 25 cases per 100,000 population per year. Seasonal variation in the occurrence of subarachnoid hemorrhage has been reported in studies from different countries, with significant seasonal variations and peak periods… 
Recovery from diffuse brain injuries: Two case studies.
This chapter presents two case studies and cognitive language rehabilitation strategies following diffuse brain injuries and autoimmune encephalopathies and suggests speech‐language pathologists should be well equipped to provide therapy with these types of injuries.
Traumatic Neuroemergency: Imaging Patients with Traumatic Brain Injury—An Introduction
The role of imaging in the prediction of prognosis is well established and of growing importance in the research arena and may influence life or death decisions.
Anesthetic Management of Traumatic Brain Injury
The purpose of this review article is to highlight initial management of a TBI patient, securing an airway, and recommendations for intraoperative management.
Traumatic brain injuries in illustrated literature: experience from a series of over 700 head injuries in the Asterix comic books
Although over half of patients had an initially severe impairment of consciousness after TBI, no permanent deficit could be found and Roman nationality, hypoglossal paresis, lost helmet, and ingestion of the magic potion were significantly correlated with severe initial impairment of conscience.
The influence of gender on the injury severity, course and outcome of traumatic brain injury
Outcome parameters were affected foremost by initial injury severity and by age, but not by sex, and pituitary insufficiency was not affected by sex or age.
Traumatic brain injury induced hypopituitarism in children and adolescents
TBI-induced hypopituitarism may have serious outcomes on growth, pubertal development, body composition, bone and brain development and function, which all affect recovery and rehabilitation of these young people after TBI.
The clinical significance of small subarachnoid hemorrhages
Patients with low-grade tSAH spent less time in the ICU, demonstrated neurological and medical stability during hospitalization, and did not experience seizure during their admission, suggesting that patients with small subarachnoid hemorrhage may not require as aggressive monitoring as is currently provided for those with t SAH.
Functional Outcome of the Patients with Acute Subdural Hematoma Treated Surgically within 4 hours of Injury
The magnitude of outcome of early intervention for removal of acute subdural hematoma found to be satisfactory and should be followed, which may decrease the morbidity and mortality.

M Males and the elderly are at the highest risk for acquiring sTBI and may represent target groups for preventive efforts in a large Canadian region.
Declining Mortality From Subarachnoid Hemorrhage: Changes in Incidence and Case Fatality From 1985 Through 2000
The decline in SAH mortality has different explanations in men ( Declining incidence) and in women (declining CF).
Cognitive deficits in the acute stage after subarachnoid hemorrhage.
The results emphasize that the severity of SAH (Fisher score) is the most important factor related to cognitive dysfunction, but frontal hematoma, intraventricular hemorrhage, and acute hydrocephalus were also associated with cognitive deficits, compared with patients with SAH without these findings.
Incidence and Early Prognosis of Aneurysmal Subarachnoid Hemorrhage in Kumamoto Prefecture, Japan
The community incidence and early prognosis of first-ever aneurysmal subarachnoid hemorrhages (SAHs) to obtain the same prognostic information used by physicians and families in a defined geographic area in Japan was analyzed.
Risk factors for aneurysmal subarachnoid hemorrhage in patients in Izumo City, Japan.
Hypertension was the most notable risk factor for aneurysmal SAH, regardless of age and sex, followed by cigarette smoking in younger men and hypercholesterolemia in older women and diabetes mellitus and heart disease decreased the risk of SAH.
Predictors of Cognitive Dysfunction After Subarachnoid Hemorrhage
Treatment strategies aimed at reducing neurological injury related to generalized brain swelling, infarction, and clot-related hemotoxicity hold the best promise for improving cognitive outcomes after SAH.
The epidemiology of traumatic brain injury in Wisconsin, 2001.
TBI is a major cause of death and hospitalizations in Wisconsin, male teens and young adults, and the elderly are high-risk groups for TBI, and preventive measures should be aimed at these high- risk groups.
Recovery and rehabilitation following subarachnoid haemorrhage: Part II. Long-term follow-up.
The majority of SAH survivors who received inpatient rehabilitation attain physical independence, but many continue to have cognitive impairments which result in social and vocational disabilities.
Regional differences in outcome from subarachnoid haemorrhage: comparative audit
All patients presenting with a subarachnoid haemorrhage confirmed on computed tomography or lumbar puncture between 1992 and 1998 are audited.
[Primary loss of consciousness and amnesia in subarachnoid hemorrhage--a quantitative study].
A significant proportion of all SAH suffered LOC and amnesia occurred in the majority of cases, and SAH therefore are events which with respect to LOC andAmnesia bear some resemblance with closed head injuries.
