In global anesthesia the patient should not experience psychological trauma but the level of arousal should be compatible with clinical exigencies. Midline structures in the brainstem and thalamus necessary to regulate the level of brain arousal. Small, bilateral lesions in many of these nuclei cause a global loss of consciousness. [25]
Traumatic memories are formed after an experience that causes high levels of emotional arousal and the activation of stress hormones. These memories become consolidated , stable, and enduring long-term memories (LTMs) through the synthesis of proteins only a few hours after the initial experience.
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 DSM-5 specifies that there is a higher prevalence of acute stress disorder among females compared to males due to neurobiological gender differences in stress response, as well as an alleged higher risk of experiencing traumatic events (a now defunct assumption originating from the continued prevalence of the Duluth Model in the legal ...
Traumatic brain injury (TBI, physical trauma to the brain) can cause a variety of complications, health effects that are not TBI themselves but that result from it. The risk of complications increases with the severity of the trauma; [1] however even mild traumatic brain injury can result in disabilities that interfere with social interactions, employment, and everyday living.

PTSD patients who have gone through different traumatic experiences will have small variances in their symptoms, mostly insignificant. For example, PTSD patients who were rape victims will have aversion to words such as touch and dirty while patients who were in a fire or war experience will respond similarly to words like burn or fight. [32]

Sleep disorder is a common repercussion of traumatic brain injury (TBI). [1] [2] It occurs in 30%-70% of patients with TBI. [1] [2] TBI can be distinguished into two categories, primary and secondary damage. Primary damage includes injuries of white matter, focal contusion, cerebral edema and hematomas, [3] mostly occurring at the moment of the ...
