The test, which can be self-administered or given by an interviewer, asks patients to rate the severity of 16 different symptoms commonly found after a mild traumatic brain injury (MTBI). [6] Patients are asked to rate how severe each of the 16 symptoms has been over the past 24 hours.
BrainScope Company, Inc. (BrainScope) is a medical neuro-technology firm utilizing EEG technology to assess the full spectrum of mild traumatic brain injury (mTBI), including functional injuries (such as a concussion), and structural injuries (such as a brain bleed).
Patients recovering from traumatic brain injury (on average measuring in severely impaired ranged on the Glasgow Coma Scale) showed high stability in WTAR scores during their recovery period while performing highly similar to demographic estimates, suggesting the test is a reliable estimate of premorbid intelligence in individuals with TBI.

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]
The Disability Rating Scale (DRS) was developed as a way to track a traumatic brain injury patient from 'Coma to Community'. The scale was used to rate the effects of injury and decide how long recovery might take. The rating gives insight into the cognitive impairment of the individual with the TBI. [1]
The Westmead Post-traumatic Amnesia Scale (WPTAS) is a brief bedside standardised test that measures length of post-traumatic amnesia (PTA) in people with traumatic brain injury. It consists of twelve questions that assess orientation to person, place and time, and ability to consistently retain new information from one day to another.
The test requires both attention and working memory which are difficult functions for people with mild traumatic brain injury. The question being studied, is whether results for people with brain injury will show visual-tracking gaze errors relative to the moving target.
Taking less than 15 minutes to administer, it involves collecting a history of the injury event and the symptoms experienced at that time, followed by a brief neurological screening, and a similarly short cognitive test. The score is presented with a listing of symptoms endorsed and a red or green light regarding the neurological screen.
