Post-traumatic amnesia ( PTA ) is a state of confusion that occurs immediately following a traumatic brain injury (TBI) in which the injured person is disoriented and unable to remember events that occur after the injury . The person may be unable to state their name, where they are, and what time it is. When continuous memory returns, PTA is considered to have resolved. While PTA lasts, new events cannot be stored in the memory. About a third of patients with mild head injury are reported to have "islands of memory", in which the patient can recall only some events. During PTA, the patient's consciousness is "clouded". Because PTA involves confusion in addition to the memory loss typical of amnesia, the term "post-traumatic confusional state" has been proposed as an alternative.

The majority of neuropsychological studies available have suggested that the medial temporal lobes are the most important system in the pathophysiology of PTA. However, there is little research done on this topic, and as new research is done, more information should come forth concerning functionality in these areas in PTA patients. One MRI study showed that

Frontal lobe lesions may also play a role in PTA, as damage to these areas is associated with changes in behavior, including irritability, aggressiveness, disinhibition, and a loss of judgment. Damage to this area may account for the uncharacteristic behavior often exhibited in PTA patients. Researchers have also found that individuals experiencing PTA show accelerated forgetting. This contrasts with

5379-403: A retrospective method was used to determine the patient's condition, consisting of one or more interviews with the patient after the episode of PTA was judged to be over. The retrospective method, however, fails to account for the apparent lucidity of patients who are still experiencing substantial disorientation, or the finding that the recovery from post-traumatic amnesia is often characterized by

Attention is a cognitive resource that contributes to many mental functions. The ability to engage attention requires a certain level of conscious awareness, arousal and concentration, all mechanisms that are generally impaired by traumatic brain injury. The involvement of attention in such

6846-506: A traumatic brain injury resulting in PTA. Those still experiencing PTA performed significantly worse on both the performance and the verbal subscales of the WAIS. Also, people in early stages of PTA have substantial impairment to anterograde memory function. For example, in the case report of a patient referred to as "JL", Demery et al. noted that his memory impairments were so severe following his injury that he had forgotten that he had attended

7009-690: A true amnesiac state. In more severely brain-damaged individuals, the damage to the temporal lobes and the frontal lobes serves as good indication that amnesia will result. Patients with more chronic forms of memory impairment showed poor performance when tested with PTA scales, making differentiation between the two types of memory impairment very difficult. PTA patients exhibit poor simple reaction time , reduced information processing speed and reduced verbal fluency, which are all attentional deficits that could be used to distinguish these patients from those with more severe and permanent memory problems. The effects of PTA on communication skills were studied using

Capcom later confirmed this character to be Chris, in spite of

8639-726: Is generally positive. Many patients do recover a great deal of cognitive function, although they may not return to their pre-injury state. Early research pointed to vasopressin as a potential treatment for improving the memory of patients living with post-traumatic amnesia (PTA). Lysine vasopressin, a modified form of the vasopressin molecule, had positive effects on memory when administered by injection to patients with amnesia resulting from traumatic brain injury and Korsakoff's syndrome . Subsequent animal studies with rats found similar results, particularly in aversion and avoidance learning tasks. Rats lacking adequate vasopressin, either due to genetic defect or hypophysectomy (surgical removal of

The GOAT's assessment of orientation may put too much of a focus on memory as the main mechanism behind orientation.

12388-649: The Revised Edinburgh Functional Communication Profile (REFCP), which measures both linguistic elements (related to speech) and pragmatic elements (related to body language and other non-verbal communication skills). PTA has effects on memory, perception and attention, which are all important for communication. Patients showed mild deficits in verbal communication skills, and moderate to severe deficits in nonverbal communication skills such as maintaining eye contact, initiating greetings, and responding appropriately. Also,

12877-474: The United States and Canada. The test is made up of 10 items that assess orientation and recollection of the events before and after the injury. It can be used to assess the duration of PTA; this particular GOAT assessment has been found to strongly predict functional outcome as measured by the Glasgow Outcome Scale , return to productivity, psychosocial function and distress. An alternative to

13040-416: The United States, it was pointed out that securing the rights to the name Biohazard would be very difficult as a DOS game had been registered under that name, as well as a New York hardcore punk band called Biohazard . A contest was held among company personnel to choose a new name; this competition turned up Resident Evil , the name under which it was released in the west. Resident Evil made its debut on

13529-401: The beginning of the Resident Evil series, the designers have been making his appearance "incredibly muscular" and "buff" ever since Resident Evil 5 . Near the climax of Resident Evil 5 , Chris pushes and punches a large boulder until it falls into the lava. The scene became recognized as one of the most memorable within the Resident Evil series, largely due to its ridiculousness. It became

13692-571: The best selling game of the franchise despite mixed fan reception. Capcom revealed the third-person shooter Resident Evil: Operation Raccoon City , which was developed by Slant Six Games for the PlayStation 3, Xbox 360 and Windows and released in March 2012.

One notable addition from the novels is the original character Trent, who often served as a mysterious behind-the-scenes string-puller who aided the main characters. Perry's novels were translated and released in Japan with new cover arts by Wolfina. Perry's novels, particularly The Umbrella Conspiracy , also alluded to events in Biohazard: The Beginning , such as

14181-476: The character's lack of consistent visual design for his appearances throughout the Resident Evil franchise. Polygon ' s Cass Marshall noted his variations in body mass throughout the games by repeatedly changing from lean to muscular and back again. GameSpy called his design in Resident Evil 5 "a cross between Colin Farrell and Hugh Jackman " in particular, and it became a source of controversy and

14344-449: The course of the series. Resident Evil 5 (2009) features Chris as a protagonist; designers opted to focus on how the character had aged since the original game. His increased muscle mass was to show that he had trained heavily in order to fight the series' powerful villain, Albert Wesker , bare-handed. Modeler Yosuke Yamagata added that they "made a new design that retained their signature color—green for Chris, blue for Jill—to carry over

14507-469: The direction of Osamu Yagihashi. The stage play was performed from early July to late August. Biohazard The Stage was released in Japan in 2015.

The production was handled by Avex Live Creative and Ace Crew Entertainment, under supervision from Capcom. The following year, Musical Biohazard ~Voice of Gaia~

14670-454: The direction the player pushes the controls from the perspective of the camera. Some critics have posited that the control scheme is intentionally clumsy, meant to enhance stress and exacerbate difficulty. While the first three entries in the series featured this control scheme, the third, Resident Evil 3: Nemesis , saw some action-oriented additions. These included a 180 degree turn and dodge command that, according to GameSpot , "hinted at

Although it has not yet been thoroughly investigated, there is potential for stimulants , which promote catecholamine release, to be an effective treatment in the early stages of recovery from brain trauma, and these positive effects could reduce

15159-400: The episode of PTA. Researchers noted that the damage was related to vascularization and neural functionality, but not to structural injury, suggesting that the resolution of PTA is dependent on functional changes. Memory and new learning involve the cerebral cortex , the subcortical projections, the hippocampus , the diencephalon and the thalamus , areas that often experience damage as

15322-478: The events in the sequel. Set five months later, Resident Evil - Code: Veronica (2000) sees Chris return as the protagonist of the second half of the game.

Some critics also mentioned that Chris' possibility of using steroids due to his hypermasculinity . Several game publications have noted

15974-482: The fifth and final issue. Each issue was a compilation of short stories that were both adaptations of events from the games and related side stories. Like the Perry novels, the comics also explored events occurring beyond Resident Evil 2 (the latest game during the series' publication) and thus were contradicted by later games. Wildstorm also published a four-issue miniseries, Resident Evil: Fire & Ice , which depicted

16137-665: The filmmakers put together a montage of noteworthy video game scenes that related to or clarified the mythology or history of his character as part of [his] research. Robbie Amell played him in Resident Evil: Welcome to Raccoon City .

It was a musical horror-comedy but took the perspective of the infected. Super Eccentric Theater put on the production under

16626-413: The first time, fully abandoning the series' signature tank controls. Resident Evil 7 is the first main Resident Evil game to use the first-person perspective and to use virtual reality . It drew comparisons to modern survival horror games such as Outlast and PT . The eighth main-series game, Resident Evil Village , also features a first-person perspective. A VR version of Resident Evil 4

16789-490: The franchise shifted to more dynamic shooting action, popularizing the "over-the-shoulder" third-person view in action-adventure games.

17604-469: The hippocampal region of the brain. The amygdala , an area of the brain involved in emotional regulation, may be involved in producing remembrance for some aspects of the trauma. Even though the trace of a memory for trauma may be lost from the hippocampus, it may remain partially encoded in the form of an emotional memory in the amygdala where it can be subsequently recalled in the form of a flashback or partially recovered memory . Diaschisis refers to

17767-399: The injury) and anterograde amnesia (problems with creating new memories after the injury has taken place). PTA may refer to only anterograde forms, or to both retrograde and anterograde forms. A common example in sports concussion is the quarterback who was able to conduct the complicated mental tasks of leading a football team after a concussion, but has no recollection the next day of

17930-468: The injury, along with the duration of loss of consciousness (LOC), and scores on the Glasgow Coma Scale (GCS), which measures degrees of consciousness, with higher scores indicating higher levels of functioning. A score of three indicates complete unconsciousness, and a score of 15 indicates normal functioning. In patients experiencing PTA for the duration of: Up to one hour – the injury

18093-425: The injury. 1–2 weeks – the injury is very severe, and recovery is likely to take many months. The patient is likely to experience long-lasting cognitive effects such as decreased verbal and nonverbal intelligence as well as decreased performance on visual tests. Patients should, however, still be able to return to work. 2–12 weeks – the injury is very severe, and recovery is likely to take a year or more. The patient

18256-421: The lack of any ill effects suggests that vasopressin is, at the least, a possible enhancement for a treatment regimen. Diaschisis , as mentioned earlier, has been linked to the mechanism of PTA. The noradrenergic systems may play a role in diaschisis. Norepinephrine , also known as noradrenalin, is a catecholamine neurotransmitter . Administering a norepinephrine receptor agonist (a substance that initiates

18419-470: The length of amnesia is still the a behavioural measure, the duration of the episode of post-traumatic amnesia, rather than a neuroimaging technique or an electrophysiological or biochemical technique. The length of amnesia is also one of the most accurate predictors for determining later cognitive problems, even more so than the duration of either the coma or the period of loss of consciousness. The duration of amnesia after TBI, therefore, can be very useful in

18582-514: The levels of acetylcholine in the brain. This idea is supported by the fact that there is an increase in acetylcholine concentrations in the brain after head injury. Animal studies have shown that concussive injuries in rats lead to changes in the central nervous system 's cholinergic system. This increase in acetylcholine levels has also been tied to behavioral suppression and unconsciousness, both symptoms of PTA. In long-term recovery, acetylcholine levels associated with diaschisis may continue to play

18745-431: The likelihood that psychiatric and behavioral problems will occur as consequences of TBI. Classification systems for determining the severity of TBI may use duration of PTA alone or with other factors such as Glasgow Coma Scale (GCS) score and duration of loss of consciousness (LOC) to divide TBI into categories of mild, moderate, and severe. One common system using all three factors and one using PTA alone are shown in

18908-422: The next numbered entry in the main series, Resident Evil 6 , was released to mixed reviews, but enthusiastic pre-order sales. In 2013, producer Masachika Kawata said the Resident Evil franchise would return to focus on elements of horror and suspense over action, adding that "survival horror as a genre is never going to be on the same level, financially, as shooters and much more popular, mainstream games. At

19071-410: The normal forgetting observed by patients with normal amnesia related to brain damage. The temporal lobes are often the most vulnerable to the diffuse (widely distributed) and focal (more specifically localized) effects of TBI and it is possible that temporal lobe lesions may account for the accelerated forgetting observed in patients with PTA. These predictions were supported by the finding that most of

19234-401: The noticeable change in his appearance. Chris appeared in the downloadable content campaign Not a Hero , which was released on December 12, 2017. This subchapter focuses on Chris attempting to apprehend Lucas Baker , and although he fails to save his men, he confronts and kills Lucas. Chris returned for the eighth main installment in the series, titled Resident Evil Village (2021). During

The STARS team is mostly decimated by zombies and other BOWs, leaving only a handful of survivors, including Chris Redfield , Jill Valentine , and Albert Wesker . Chris and Jill explore the zombie-infested mansion and uncover

19723-409: The original Resident Evil , in which Chris investigates the disappearance of his missing friend, Billy Rabbitson. S. D. Perry has written novelizations of the first five games, as well as two original novels taking place between games. The novels often take liberties with the games' plot by exploring events occurring outside and beyond the games. This often meant that the games would later contradict

19886-1216: The original Resident Evil ; Michael Filipowich voiced in Resident Evil – Code: Veronica ; Joe Whyte in the 2002 remake of Resident Evil ; Kevin Dorman in Resident Evil: The Umbrella Chronicles , Resident Evil: Vendetta , and Resident Evil: Death Island ; Roger Craig Smith in Resident Evil 5 and Resident Evil 6 . David Vaughn voiced him in Resident Evil 7 , while Jeff Schine in Resident Evil: Village . In Japanese, Subaru Kimura voiced him in Resident Evil: Welcome to Raccoon City . Reuben Langdon did Chris' motion capture in Code: Veronica , Resident Evil 5 , and Resident Evil 6 , while Geordie Dandy did it in Resident Evil 7 and Village . Wentworth Miller portrayed him in Resident Evil: Afterlife . Miller said he requested that

20049-421: The part of the game that took place after the injury. Individuals with retrograde amnesia may partially regain memory later, but memories are not regained with anterograde amnesia because they were not encoded properly. The term "post-traumatic amnesia" was first used in 1940 in a paper by Symonds to refer to the period between the injury and the return of full, continuous memory, including any time during which

20212-416: The patient is still in a state of PTA or if they are experiencing a more permanent form of memory deficit. In patients with mild TBI, the damage consists primarily of diffuse axonal injury (widespread damage to white matter) without any focal damage (damage to specific areas). Sometimes, injury of the brainstem was also observed. In these cases, there is likely the presence of an attentional deficit without

20375-688: The patient was unconscious. The most prominent symptom of post-traumatic amnesia (PTA) is a loss of memory of the present time. As a result, patients are often unaware of their condition and may behave as if they are going about their regular lives. This can cause complications if patients are confined to a hospital and may lead to agitation, distress and anxiety . Many patients report feeling as though they were being "held prisoner" and being prevented from carrying on with their daily lives. Other symptoms include agitation, confusion , disorientation , and restlessness. Patients also often display behavioral disturbances. Patients may shout, swear and behave in

20538-399: The patients who showed rapid forgetting also had lesions to the temporal lobe. Bilateral damage to the temporal lobes also causes severe anterograde amnesia, making it likely that lesions to this area would be involved in PTA. Patients exhibit a temporal gradient with memory loss, meaning that older memories are preserved at the expense of newer memories. Temporal lobe damage has been linked to

20701-408: The person, orientation to the place, and orientation to the time. The idea behind these questions is that each of these classifications places a large demand on the patient's memory and learning abilities. The Westmead Post-Traumatic Amnesia Scale (WPTAS) is commonly used in Australia and New Zealand. It questions twelve questions that examine orientation to person, place and time, in addition to

20864-450: The pituitary gland), exhibited significant improvements in memory and learning functions when exogenous vasopressin was administered. Particularly encouraging was the finding that a short treatment period produced long-lasting improvements, in both humans and rats. However, the animal models of PTA are highly limited, as the dimension of self-awareness and orientation is almost impossible to model adequately. PTA in animals, especially rats,

21027-452: The player views the current scene. Pressing up (for example on a D-pad , analog stick , or cursor movement keys ) on the game controller moves the character in the direction being faced, pressing down backpedals, and left and right rotates the character. This can feel counter-intuitive when the character is facing the camera, as the controls are essentially reversed in this state. This differs from many 3D games, in which characters move in

21190-470: The prequel Resident Evil Zero , both released in 2002, as well as Resident Evil 4 (2005)—were all released initially as GameCube exclusives. Resident Evil 4 was later released for Windows, PlayStation 2, and Wii . A trilogy of GunCon -compatible light gun games known as the Gun Survivor series featured first-person gameplay. The first, Resident Evil Survivor , was released in 2000 for

21353-427: The presence of "islands of memory" (short periods of clarity). A failure to take these facts into consideration may have biased retrospective methods towards underestimating the length and severity of an episode of PTA. Also, the retrospective method relies on retrospective memory , one's memory for past events, which is not very reliable in healthy individuals, and even less so in patients who have recently experienced

21516-491: The publication of Apocalypse , Genesis being marketed as a prequel to Apocalypse , while the Extinction novel was released in late July 2007, two months before the film's release. The Final Chapter was published in December 2016 alongside the film's theatrical release. There was also a Japanese novelization of the first film, unrelated to DeCandido's version, written by Osamu Makino. Makino also wrote two novels based on

21679-555: The reboot film Resident Evil: Welcome to Raccoon City (2021). Chris also appears in the adult animated Resident Evil films. He was one of the main characters in Resident Evil: Vendetta (2017), alongside Leon and Rebecca. Unlike the live-action films, the animated films are in the same continuity as the games. He returned in the sequel, Resident Evil: Death Island (2023). Chris is a playable character in several non-canonical Resident Evil games. He features in

Resident Evil 5 ' s producer Jun Takeuchi said that the series' fans "would really love" a video game featuring both Leon S. Kennedy and Chris as the protagonists due to their popularity, and at the same time, it would be "pretty dramatic" if

22331-446: The same time, I think we need to have the confidence to put money behind these projects, and it doesn't mean we can't focus on what we need to do as a survival horror game to meet fan's needs." Resident Evil: Revelations 2 , an episodic game set between Resident Evil 5 and Resident Evil 6 , was released in March 2015. A series of team-based multiplayer games were developed beginning with the poorly received Umbrella Corps , which

Wes Fenlon of PC Gamer said that Chris punching a boulder inside an active volcano "gave us what is truly one of the greatest moments in the history of videogames" and "as a quicktime event. It is perfect." In Resident Evil Village , during the boss fight with Karl Heisenberg, Karl calls Chris a "boulder-punching asshole,"

22820-663: The success of the GOAT and the Orientation Log (O-Log) in predicting rehabilitation outcomes, and found that, while the O-Log and the GOAT perform similarly as measures of PTA severity and duration, the O-Log provides a more accurate picture of rehabilitation. While the GOAT is a useful tool, these results suggest that using alternative methods of assessing PTA may increase the amount of information available to physicians and may help in predicting rehabilitative success. The international cognitive (INCOG) expert panel has recommended

22983-411: The sudden dysfunction of portions of the brain due to lesions in distant but connected neurons . Diaschisis is implicated as playing an important role in PTA, more particularly in the declarative memory impairments observed in patients experiencing an episode of PTA. The loss of function observed after traumatic brain injuries, as well as the resulting loss of consciousness, was thought to be mediated by

23146-445: The symptoms of PTA. The North Star Project was developed by researchers at McGill University . Researchers developed a "reality orientation", which involved discussing general facts (e.g. date, time, names of family members, etc.) with amnesic patients twice a day in an attempt to lessen their confusion during the early stages of their recovery. Younger patients often had shorter amnesic episodes than older patients, especially those in

23309-451: The tables at right. Duration of PTA usually correlates well with GCS and usually lasts about four times longer than unconsciousness. PTA is considered a hallmark of concussion , and is used as a measure of predicting its severity, for example in concussion grading scales . It may be more reliable for determining severity of concussion than GCS because the latter may not be sensitive enough; individuals with s concussion often quickly regain

23472-491: The third-highest-grossing video game film series . The development of the first Resident Evil , released as Biohazard in Japan, began in 1993 when Capcom 's Tokuro Fujiwara told Shinji Mikami and other co-workers to create a game using elements from Fujiwara's 1989 game Sweet Home on the Family Computer (Famicom) in Japan. When in late 1994 marketing executives were setting up to release Biohazard in

23635-457: The time of the project," he says, referencing the DLC's early days of planning, "there were some ideas that focused on Chris. But we wanted to focus on Rose Winters," disclosing that the crew had a preference for a DLC that starred Rose as the main character rather than having Chris rejoin the action. In the original Resident Evil , which uses live-action cinematics , Chris is played by Charlie Kraslavsky. Scott McCulloch voiced Chris in

23798-651: The two characters never met before the series would end; this eventually occurred in Resident Evil 6 (2012). In Resident Evil 6 , Chris has a slightly disheveled look due to his alcoholism and post-traumatic amnesia . In Resident Evil 7 (2017), Chris was given an entirely new design as the producers wanted to give him a more realistic look. The character's new design made him completely "unrecognizable", as stated by commentators and players. Director Kōshi Nakanishi stated that Resident Evil 6 ' s Chris model "was just not suitable for Resident Evil 7 ' s game engine or aesthetic". He further said that "[a]lthough it

23961-432: The use of a validated PTA scale such as the GOAT or WPTAS for assessing PTA duration in patients with moderate-to-severe traumatic brain injury on a daily basis. The severity of post-traumatic amnesia (PTA) is directly related to its duration, although a longer duration does not necessarily indicate more severe symptoms. The duration of PTA in brain-injured patients is a useful predictor of the expected long-term effects of

24124-519: The viral outbreak. Leon, Claire, Sherry, Ada, and Jill escape the city before its eradication. Claire continues to look for Chris, whereas Leon is recruited to work for the U.S. Government. Resident Evil – Code: Veronica follows Claire as she escapes from a prison camp in the Southern Ocean and later reunites with Chris at an Umbrella research facility in Antarctica . Resident Evil 4

24287-502: The weaknesses of the method most often used in assessing PTA, the Galveston Orientation and Amnesia Test (GOAT), is that it does not include any assessment of attention, which could help give a better indication of potential for recovery. By omitting attention, the test is omitting some crucial aspects of a person's cognitive capabilities. In addition, assessing attention during the period of PTA may help determine whether

24450-411: The years, various toy companies have acquired the Resident Evil license, with each producing their own unique line of Resident Evil action figures or models. These include, but are not limited to, Toy Biz , Palisades Toys , NECA , and Hot Toys .
