¶ 1. In this personal injury action, plaintiff appeals the Caledonia Superior Court’s August 28, 2003 decision granting defendants’ motion to dismiss. Plaintiff argues on appeal that this action is *53 sufficiently distinct from the lawsuit she filed, and eventually won, for injuries sustained as a result of the same occurrence giving rise to her current lawsuit. Because we agree with the trial court that the doctrine of claim preclusion bars plaintiff from relitigating the personal injury claims she pressed in her first lawsuit, we affirm.
¶ 2. The parties do not contest the relevant facts. In 1991, plaintiff sustained injuries when a large metal panel struck her head while she was on an amusement ride at the Caledonia County Fair run by defendant Caledonia County Fair Association (County Fair). In 1994, plaintiff sued the operator of the ride, defendant Marc’s Amusement Co., Inc. (Marc’s), for damages resulting from her head injuries. In 1995, the U.S. District Court rendered a verdict in her favor for $5,000, and she successfully collected that amount.
¶ 3. On November 12, 1999, plaintiff suffered her first grand mal seizure. On April 5, 2000, her treating physician diagnosed her with epilepsy and determined that the 1991 head injury was the proximate cause of the epilepsy. In November 2002, plaintiff sued both defendants, seeking damages for the epilepsy that allegedly resulted from the 1991 injury. Defendants jointly filed a motion to dismiss in May 2003.
¶ 4. In the decision currently on appeal, the trial court granted defendants’ motion to dismiss on two grounds. First, the court agreed with defendants that plaintiff’s epilepsy claim was barred by the doctrine of claim preclusion, 3 because plaintiff’s current claim differs from her 1994 claim only in that she currently alleges a more serious injury to her head. Further, the court held that its ruling applied to both defendants (even though plaintiff sued only Marc’s in her first action) because they were in privity. Second, the trial court found that plaintiff’s claim was time-barred under 12 V.S.A. § 512(4). 4 Plaintiff then filed this appeal.

¶ 5. In reviewing a trial court’s grant of a motion to dismiss, this Court accepts as true “all factual allegations pleaded in the complaint” and draws “all reasonable inferences from those facts.”
Gilman v. Maine Mut. Fire Ins. Co.,
¶ 6. As a preliminary matter, we note that plaintiff does not challenge the trial court’s conclusion that, by virtue of the indemnity obligation and the unity of interests between them, privity exists between the two defendants for claim preclusion purposes. See
In re Dunnett,
¶ 7. The crux of plaintiff’s argument is that the trial court erred in applying claim preclusion because the cause of action in her current lawsuit is distinct from her prior lawsuit. However, as the trial court correctly explained, “plaintiff is pursuing the identical case she pursued in 1994 except that she is alleging that the injury to her head was more serious.”
¶ 8. Under the doctrine of claim preclusion, a final judgment in previous litigation bars subsequent litigation if the parties, subject matter, and cause(s) of action in both matters are the same or substantially identical.
Pomfret Farms Ltd. P’ship v. Pomfret
Assocs.,
¶ 9. The doctrine of claim preclusion advances the efficient and fair administration of justice because it serves “(1) to conserve the re
*55
sources of courts and litigants by protecting them against piecemeal or repetitive litigation; (2) to prevent vexatious litigation; (3) to promote the finality of judgments and encourage reliance on judicial decisions; and (4) to decrease the chances of inconsistent adjudication.”
In re CVPSC,
ensures “the very object for which civil courts have been established, which is to secure the peace and repose of society by the settlement of matters capable of judicial determination. Its enforcement is essential to the maintenance of social, order; for, the aid of judicial tribunals would not be invoked ... if... conclusiveness did not attend the judgments of such tribunals.”
Nevada,
¶ 10. The policies underlying the doctrine of claim preclusion are so fundamental to our precedent-based legal system that the U.S. Supreme Court has refused to recognize “public policy” and “simple justice” as rationales for avoiding the doctrine’s strict application.
Federated Dep’t Stores, Inc. v. Moitie,

¶ 11. With these considerations in mind, we turn to the question of whether plaintiff’s current lawsuit articulates a new claim, or attempts to relitigate the claim concluded by her prior lawsuit. In determining whether two causes of action are sufficiently similar for claim preclusion purposes, this Court has focused on whether the same evidence will support both of them. See, e.g.,
State v. Dann,
¶ 12. As the UN Supreme Court has noted, however, “[d]efinitions of what constitutes the ‘same cause of action’ have not remained static over time.”
Nevada,
¶ 13. Under the second Restatement, the scope of a “transaction” is determined by “giving weight to such considerations as whether the facts are related in time, space, origin, or motivation, whether they form a convenient trial unit, and whether their treatment as a unit conforms to the parties’ expectations or business understanding or *57 usage.” Restatement (Second) § 24(2). In making this assessment, “no single factor is determinative.” Id. §24 cmt. b. Additionally, “even when there is not a substantial overlap [between proofs relevant to two actions], the second action may be precluded if it stems from the same transaction.” Id. Thus, it follows from this flexible definition that “where one act causes a number of harms to, or invades a number of different interests of the same person, there is still but one transaction.” Id. § 24 cmt. c.
¶ 14. Indeed, the current Restatement’s approach precludes a second lawsuit arising out of the same transaction as a prior lawsuit even where the second action will include “evidence or grounds or theories of the case not presented in the first action, or... remedies or forms of relief not demanded in the first action.” Id. § 25. Moreover, “ [i]t is immaterial that in trying the first action [plaintiff] was not in possession of enough information about the damages, past or prospective, or that the damages turned out in fact to be unexpectedly large and in excess of the judgment.” Id. § 25 cmt. c (emphasis added).
¶ 15. Adopting these principles, we conclude that plaintiff’s claim for relief in the instant case arises out of the same transaction that gave rise to the prior lawsuit. The facts underlying both eases are inextricably “related in time, space, origin, or motivation,” Restatement (Second) § 24(2), because both actions spring from the same “origin” — the 1991 accident. As a result, there is substantial overlap between the proofs of both claims, with the only difference being evidence concerning the existence and cause of plaintiff’s epilepsy. However, this discrepancy does not necessarily militate in favor of finding two distinct transactions, because “even when there is not a substantial overlap [of witnesses and proofs], the second action may be precluded if it stems from the same transaction.” Id. § 24 cmt. b. Indeed, viewed together, plaintiff’s two lawsuits depict one act — the 1991 accident — that caused harm to plaintiff. In such situations, “there is still but one transaction.” Id. § 24 cmt. c.
¶ 16. Finally, viewing the two cases as stemming from the same transaction does not undermine the expectations of the parties. There is nothing in the record to suggest that, at the time of plaintiff’s first lawsuit, either party expected anything other than the typical result in a personal injury case — namely, a verdict that would conclude the matter between them. As the Restatement approach recognizes, “even when the injury caused by an actionable wrong extends into the Mure and will be felt beyond the date of judgment, the damages awarded by *58 the judgment are nevertheless supposed to embody the money equivalent of the entire injury.” Id. § 25 cmt. c. Therefore, the fact that “in trying the first action [plaintiff] was not in possession of enough information about the damages, past or prospective, or that the damages turned out in fact to be unexpectedly large and in excess of the judgment” is “immaterial” to the claim preclusion analysis. Id. (emphasis added). Accordingly, we hold that both actions arise out of the same transaction for claim preclusion purposes, and, as a result, that this action is barred by the judgment in the previous action. 5
¶ 17. This case is distinguishable from the cases upon which plaintiff relies that permitted subsequent actions for late-emerging latent diseases resulting from exposure to asbestos or other workplace chemicals. See, e.g.,
Pustejovsky v. Rapid-American Corp.,
¶ 18. The instant case is best viewed not as a latent disease case, but as a “traumatic event/latent manifestation” case, “in which the plaintiff has sustained both immediate and latent injuries caused by a noticeable, traumatic occurrence.”
Albertson v. T.J. Stevenson & Co.,
¶ 19. Finally, we reject plaintiff’s argument that Article 4 of Chapter I of the Vermont Constitution militates against applying claim preclusion here because doing so would be unfair. While the Restatement recognizes that the policies behind claim preclusion may be overcome “for an extraordinary reason,”
id.
§ 26(l)(f), such exceptions are “not lightly to be found but must be based on a clear and convincing showing of need,”
id.
§ 26 cmt. i. As examples, the Restatement offers cases involving the validity of a continuing restraint on liberty, child custody, divorce, or a prior litigation that “failed to yield a coherent disposition.”
Id.
Because plaintiff alleges only that her injuries stemming from the 1991 accident turned out to be more serious than they appeared at the time of the first lawsuit, she has not “clearly and
*60
convincingly shown that the policies favoring preclusion ... are overcome for an extraordinary reason.”
Id.
§ 26(1)(f). As explained above, the U.S. Supreme Court has recognized that “the mischief which would follow the establishment of precedent for so disregarding this salutary doctrine against prolonging strife would be greater than the benefit which would result from relieving some case of individual hardship.”
Federated Dep’t Stores,
¶ 20. We are mindful that claim preclusion may cause harsh results in individual cases, but on balance we conclude that applying it here best serves the interests of all litigants and promotes the efficient administration of justice, in light of the powerfiil policy concerns laid out above. As the U.S. Supreme Court aptly recognized, the “doctrine of res judicata is not a mere matter of practice or procedure inherited from a more technical time than ours. It is a rule of fundamental and substantial justice, of public policy and of private peace, which should be cordially regarded and enforced by the courts.” Federated Dep’t Stores, 452 U.S. at 401 (quotations omitted). Therefore, the trial court correctly dismissed the instant case.
Affirmed.
Notes
Although the trial court used the term “res judicata,” the terms “res judicata” and “claim preclusion” are often used interchangeably. See, e.g.,
In re Cent. Vt. Pub. Serv. Carp.,
Because we hold that the doctrine of claim preclusion bars plaintiff’s current lawsuit, we do not reach the issue of whether the suit was timely under 12 V.S A. § 512(4).
We also note that the Restatement contemplates an exception to the application of claim preclusion when “[t]he court in the first action has expressly reserved the plaintiff’s right to maintain the second action.” Restatement (Second) § 26(l)(b). If a party provides the court with “special reasons” for doing so, the court should afford the party “an opportunity to litigate in a second action that part of the claim which he justifiably omitted from the first action.” Id. § 26 cmt. b. The record here does not reveal that plaintiff requested or the court decided in the first action to reserve plaintiff’s right to pursue a second action in the event that her injuries turned out to be more severe.
In this regard, it is also worth noting a distinction between the criteria for application of claim preclusion and those used in the context of the related concept of issue preclusion (or collateral estoppel). “[Ijssue preclusion bars the subsequent relitigation of an issue which was actually litigated and decided in a prior case between the same parties resulting in a final judgment on the merits, where that issue was necessary to the resolution of the action.” Am.
