Objectives include: 1) establishing a psychometrically sound traumatic brain injury (TBI) screening measure for use among homeless veterans; 2) identifying the prevalence of those that screen positive for TBI among homeless veterans seeking VA services; and 3) comparing psychiatric outcomes between those with and without a history of TBI.
Short-term Objectives include:
1. Establishing the criterion-related validity of the Traumatic Brain Injury-4 (TBI-4) questionnaire in the Veteran homeless population using the Ohio State University TBI-Identification Method (OSU TBI-ID) (Corrigan et al., 2007) as the gold standard for establishing traumatic brain injury (TBI) diagnosis.
2. Identifying the prevalence of those that screen positive for a lifetime history of TBI among homeless Veterans.
3. Comparing psychiatric outcomes (psychiatric hospitalizations, suicide attempts and deaths, and clinical contacts) between those with and without a lifetime history of TBI.

This is a pilot study, phase III, multi-centre, double blind, randomized controlled trial of patients with traumatic brain injury (TBI).
The purpose of this research study is to evaluate whether data made by the ClearView System can be used to detect whether someone has a traumatic brain injury and how severe the injury is.
Novel biomarkers of traumatic brain injury (TBI) have been discovered in laboratory animal models. The objective of this study is to find whether similar markers are detectable in the body...

To conduct a review of literature and quantify the effect that traumatic brain injury (TBI) has on oculomotor functions (OM).
During rehabilitation from a severe traumatic brain injury, a 16-year-old woman became aware that she had lost the ability to laugh out loud. This rare phenomenon has previously been described as "aph...
Prolonged unconsciousness from which the individual cannot be aroused, associated with traumatic injuries to the BRAIN. This may be defined as unconsciousness persisting for 6 hours or longer. Coma results from injury to both cerebral hemispheres or the RETICULAR FORMATION of the BRAIN STEM. Contributing mechanisms include DIFFUSE AXONAL INJURY and BRAIN EDEMA. (From J Neurotrauma 1997 Oct;14(10):699-713)
A form of acquired brain injury which occurs when a sudden trauma causes damage to the brain.
Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.
Traumatic injuries to the cranium where the integrity of the skull is not compromised and no bone fragments or other objects penetrate the skull and dura mater. This frequently results in mechanical injury being transmitted to intracranial structures which may produce traumatic brain injuries, hemorrhage, or cranial nerve injury. (From Rowland, Merritt's Textbook of Neurology, 9th ed, p417)
Bleeding within the brain as a result of penetrating and nonpenetrating CRANIOCEREBRAL TRAUMA. Traumatically induced hemorrhages may occur in any area of the brain, including the CEREBRUM; BRAIN STEM (see BRAIN STEM HEMORRHAGE, TRAUMATIC); and CEREBELLUM.
Anxiety is caused by stress. It is a natural reaction, and is beneficial in helping us deal with tense situations and pressure. It is deterimental when is becomes an excessive, irrational dread of everyday situations. The most common types of anxiety di...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
