[¶ 1] Michael J. James appeals from an order of the Superior Court (Kennebec County, Marden, J.) discharging him from the custody of the Commissioner of the Department of Health and Human Services (DHHS), and- thereby returning him to the custody of the Department of Corrections. James contends that the court erred by discharging him from DHHS custody without finding that there was a change in the mental disease or defect that formed the basis for his initial commitment. We affirm.
I. BACKGROUND
[¶ 2] The facts underlying this appeal are not disputed, and were discussed extensively in James v. State, 2008 ME 122, 953 A.2d 1152. In 2006, while serving a sentence at the Maine State Prison, James was charged With ten counts of assaulting an officer. See id. ¶ 3. A Knox County jury found James not criminally responsible by reason of mental disease or defect, and the court ordered him committed to DHHS custody. Id.; see 15 M.R.S. § 103 (2007).1 In July 2007, James was placed at Riverview Psychiatric Center (Riverview).2 See James, 2008 ME 122, ¶ 8, 953 A.2d 1152. James’s prison sentence was tolled while he remained committed and thus upon a discharge from DHHS custody he would be delivered back into the custody of the Department of Corrections.3 Id. ¶¶ 24-25.
[¶ 3] On September 5, 2013, DHHS petitioned for James’s discharge from its custody. The court held a contested hearing on the petition on April 10, 2014. At that hearing, the court heard testimony from Miriam Davidson, a Riverview psychiatric nurse practitioner; Dr. Alexander Raev, a Riverview psychiatrist; Dr. Arthur Diroc-co, Riverview’s director of psychology; Dr. Ann LeBlanc, a forensic psychologist; and *1292Dr. Brendan Kirby, River view’s clinical director.
[¶ 4] After the hearing, the court ordered James to be discharged from DHHS custody, finding by clear and convincing evidence that he no longer suffers from a mental disease or defect. See 15 M.R.S. § 104-A(1)(B) (2014). In explaining its decision, the court stated:
[James] does have substantial capacity to appreciate the wrongfulness of his conduct at Riverview, that his activities are goal-directed notwithstanding the threats and the self-harm and the aggressive behavior, that he understands what it is he’s [d]oing and why and that all of this activity, this unsatisfactory conduct is not ... the result of a mental disease or defect.
[¶ 5] James was remanded to the custody of the Department of Corrections to serve the remainder of his prison sentence. He appeals.
II. DISCUSSION
[¶ 6] James does not challenge the factual findings made by the court in its discharge order. Instead, James argues that the court erred in ordering his discharge from DHHS custody because DHHS failed to make a necessary showing pursuant to In re Beauchene, 2008 ME 110, 951 A.2d 81, and LaDew v. Comm’r of Mental Health & Mental Retardation, 532 A.2d 1051 (Me.1987): that there was a “substantial change” in the particular mental disease or defect that formed the basis for the jury’s finding him not criminally responsible in 2006. We review such questions de novo. In re Beauchene, 2008 ME 110, ¶ 7, 951 A.2d 81.
[¶ 7] Title 15 M.R.S. § 104-A(1) (2014), provides, in relevant part, that the court must order a discharge from DHHS custody “[i]f, after hearing, [it] finds that the person may be ... discharged without likelihood that the person will cause injury to that person or to others due to mental disease or mental defect.” “[M]ental disease or defect” is defined as “those severely abnormal mental conditions that grossly and demonstrably impair a person’s perception or understanding of reality.” 17-A M.R.S. § 39(2) (2014); see also Green v. Comm’r of Mental Health & Mental Retardation, 2000 ME 92, ¶ 27, 750 A.2d 1265 (“Because the release provisions provide no definition of ‘mental disease or defect,’ we look to the Criminal Code [definition].”).
[¶ 8] Thus, the only question before the court on the section 104-A(1) discharge petition was whether James presents a danger to himself or others because of a mental disease or defect. See James, 2008 ME 122, ¶ 24, 953 A.2d 1152; see also Green, 2000 ME 92, ¶ 28, 750 A.2d 1265 (holding that the relevant inquiry is whether the mental disease or defect exists, and not whether the acquittee is symptomatic); In re Fleming, 431 A.2d 616, 618 (Me.1981) (“The operative statute requires the presiding justice to ... determine whether a petitioner is free of mental disease or defect.”). Section 104-A(1) does not require a petitioner to prove a change in circumstances from the time of the not criminally responsible verdict.
[¶ 9] Contrary to James’s argument, LaDew provides no support for the result he seeks. In that case, a defendant who had been determined not guilty by reason of insanity at a time when “Maine’s insanity defense contained both a volitional and a cognitive standard” petitioned to be released after a 1986 amendment to the Criminal Code removed the volitional aspect of the defense. LaDew, 532 A.2d at 1052. In affirming the trial court’s denial of LaDew’s petition, we said:
Rather one would reasonably expect that to be released under 15 M.R.S.A. § 104-A a BRI acquittee must show (clearly and convincingly) that the men*1293tal disease or defect by reason of which he was relieved of criminal responsibility no longer exists, or at least no longer ;poses a danger to himself or others if he is released.
Id. at 1053 (emphasis added). More than twenty years later, we applied our holding in LaDew to require another petitioner to “prove that he no longer suffered from a mental disease or defect as that term was defined in 1970 that would likely result in his being a danger to himself or others.” In re Beauchene, 2008 ME 110, ¶ 10, 951 A.2d 81 (emphasis added).
[¶ 10] Here, the trial court found that James’s dangerousness — which still exists — is not the result of a mental disease or defect and that, therefore, DHHS can no longer maintain James in its custody. The evidence supports the court’s finding by clear and convincing evidence.
The entry is:
Judgment affirmed.
