The RWPTAS has been shown to be more accurate than the Glasgow Coma Scale in the identification of cognitive deficits in patients with mild TBI. [6] The A-WPTAS is administered hourly rather than daily. It is used for measuring the length of PTA following a mild traumatic brain injury (that is, when PTA is less than 24 hours).
It is suitable for patients with moderate to severe traumatic brain injury. The WPTAS is the most common post-traumatic amnesia scale used in Australia and New Zealand. [32] An abbreviated version has been developed to assess patients with mild traumatic brain injury, the Abbreviated Westmead PTA Scale (AWPTAS). [33]
Peripheral artery disease (PAD) is a vascular disorder that causes abnormal narrowing of arteries other than those that supply the heart or brain. [5] [15] PAD can happen in any blood vessel, but it is more common in the legs than the arms. [16]
One complication in diagnosis is that symptoms of PCS also occur in people who have no history of head injury, but who have other medical and psychological complaints. [31] In one study 64% of people with TBI, 11% of those with brain injuries, and 7% of those with other injuries met the DSM-IV criteria for post-concussion syndrome. Many of ...
An AIS-Code of 6 is not the arbitrary code for a deceased patient or fatal injury, but the code for injuries specifically assigned an AIS 6 severity. [1] An AIS-Code of 9 is used to describe injuries for which not enough information is available for more detailed coding, e.g. crush injury to the head.
More than 50% of patients who suffer from a traumatic brain injury will develop psychiatric disturbances. [6] Although precise rates of anxiety after brain injury are unknown, a 30-year follow-up study of 60 patients found 8.3% of patients developed a panic disorder, 1.7% developed an anxiety disorder, and 8.3% developed a specific phobia. [7]
Concussion grading systems are sets of criteria used in sports medicine to determine the severity, or grade, of a concussion, the mildest form of traumatic brain injury.At least 16 such systems exist, [1] and there is little agreement among professionals about which is the best to use. [2]
Acute subdural hematomas have one of the highest mortality rates of all head injuries, with 50 to 90 percent of cases resulting in death, depending on the underlying brain injury. About 20 to 30 percent of patients recover brain function. [36] Higher Glasgow Coma Scale score, younger age and responsive pupils are associated with better outcomes ...
