ORDER AND JUDGMENT*
After examining the briefs and appellate record, this panel has determined unanimously to grant the parties’ request for a decision on the briefs without oral argument. See Fed. R.App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument.
Plaintiff James E. Powell appeals from a district court order affirming the Commissioner’s denial of social security disability benefits. Powell claims he is disabled as a result of a seizure disorder with associated cognitive impairment and headaches. The Administrative Law Judge (ALJ) found Powell was capable of returning to past work and, accordingly, determined he was not disabled at step four of the controlling five-step analysis. See Williams v. Bowen, 844 F.2d 748, 750-52 (10th Cir.1988) (discussing steps). Powell challenged this decisión in the district court on three grounds, which he continues to press on appeal: the ALJ should have found Powell presumptively disabled at step three under the listing for epilepsy; the ALJ improperly substituted her own opinions for those of Powell’s examining physicians; and the ALJ discounted Powell’s credibility on the basis of inaccurate facts. Directing our review exclusively to the specified issues, we agree with the district court that the ALJ’s decision in these challenged respects is supported by substantial evidence and consistent with applicable legal standards, and we therefore affirm. Berna v. Chater, 101 F.3d 631, 632 (10th Cir.1996).
Step-Three Listing Determination
The relevant listing for the type of seizures presented in Powell’s case requires:
Minor motor seizures (petit mal, psycho-motor, or focal), documented by EEG and by detailed description of a typical seizure pattern, including all associated phenomena; occurring more frequently than once weekly in spite of at least S months of prescribed treatment. With alteration of awareness or loss of consciousness and transient postictal manifestations of unconventional behavior or significant interference with activity during the day.
20 C.F.R. Pt. 404, Subpt. P, App. 1, § 11.03 (italics altered). Responding to advances in anti-convulsive therapy, the Social Security Administration sharpened the focus of the prescribed-treatment condition emphasized above by issuing a policy statement and amending the introductory section of the convulsive-disorder listings to direct that a finding of disability cannot be made without evidence dem*408onstrating therapeutic blood serum levels of the medications prescribed for an epileptic claimant. See id. at § 11.00(A); Soc. Sec. Rul. 87-6, Titles II and XVI: The Role of Prescribed Treatment in the Evaluation of Epilepsy, 1987 WL 109184 (1987). A failure to satisfy this condition undermines Powell’s claim that he was entitled to a finding of disability at step three under § 11.03.
Powell has been treated with a regimen combining the anti-convulsive medications Dilantin (phenytoin) and Tegretol (carbamazapine). There are several studies in the record assessing his blood levels for these two medications. On no occasion were normal therapeutic levels found for both. See App. II at 116, 123, 167; see also id. at 117, 121 (reports of medical consultant noting treating physician’s failure to routinely monitor blood serum levels and reciting sub-therapeutic results found when such tests were ordered). Moreover, Powell presented no evidence that these low blood serum levels were the result of an extenuating individual idiosyncracy in absorption or metabolism of the drugs.1 Indeed, he has instead admitted to some neglect in taking his medication. Id. at 192; see also id. at 156 (medical consultant report noting statement by Powell’s wife that Powell has more trouble “when he doesn’t take his medicine,” indicated lack of compliance with prescribed regimen). In sum, “the [ALJ’s] determination that [Powell] has not demonstrated compliance with his therapeutic regimen is supported by substantial evidence,” and, thus, properly precluded a decision in Powell’s favor at step three. Brown, v. Bowen, 845 F.2d 1211, 1215 (3d Cir.1988); see also Diaz v. Sec’y of Health & Human Servs., 898 F.2d 774, 777 (10th Cir.1990) (holding seizure-based impairment properly discounted for noncompliance with prescribed drug treatment, presumptively evidenced by sub-therapeutic blood levels pursuant to predecessor of policy statement noted above).
Substitution of ALJ’s Opinion for those of Examining Physicians
Powell also contends he has a mental impairment indicated by a loss of memory performance. His primary support for this contention is an October 1998 re*409port from Dr. McGirk, an examining psychologist. Despite obtaining normal results for Powell on memory tasks, Dr. McGirk diagnosed a “cognitive disorder NOS,”2 evidently based on the concurrence of the seizure disorder and Powell’s anecdotal account of memory problems. See App. II at 142-45. Several months later, another psychologist reviewed Powell’s records, noted that Dr. McGirk had diagnosed a disorder without any clinically identifiable symptoms, and concluded that Powell had “no medically determinable impairment.” Id. at 147-48. The ALJ adopted the latter assessment. Powell argues that in doing so the ALJ improperly substituted her opinion for that of Dr. McGirk. We disagree. The ALJ simply evaluated the relevant medical record and sided—quite reasonably, as the evidence noted below reflects—with one expert rather than another.
Powell’s memory functioning was assessed on several occasions and never found deficient. When he was first referred in September 1997 to Dr. Udonta, the neurologist who has treated him ever since, Powell’s mental status, specifically including memory, was evaluated without any indication of problems. See id. at 136. Thirteen months later, as noted above, Powell again produced normal results on memory tasks for Dr. McGirk. In March 1999, Powell was seen by a second neurologist, Dr. Lawton, for assessment of his seizure condition and treatment. Dr. Law-ton noted Powell’s “[mjemory appeared] intact,” though a “complaint of memory loss” was “being evaluated elsewhere.” Id. at 157. That evaluation was conducted by Dr. Green, who in April 1999 reported that “no confirmation of [memory loss] was found in test data” and, indeed, identified immediate recall as one of Powell’s cognitive strengths. Id. at 161-62 (also noting Powell performed average on long-term memory tasks and above average on short-term tasks). In light of this record, we cannot say that the ALJ’s rejection of a cognitive/memory impairment lacks substantial evidentiary support.
In a related but much more perfunctory argument, Powell notes Dr. Green’s narrative report concluded with the “diagnostic impression” of a “Pain Disorder associated with psychological factors and general medical condition,” id. at 162, and insists that the ALJ must have substituted her opinion for this expert opinion as well. However, Powell fails to mention that Dr. Green attached to his report an “Assessment of Ability to Engage in Work Related Activities (Mental),” in which he discounted the vocational significance of the suggested pain disorder by rating as “slight” or “none” the degree of oecupational/performance/social adjustments Powell would have to make to work on a daily basis and imposing no associated job limitations. Id. at 163-65. The mere presence of a condition—without any demonstrable work-related impact—will not support a disability claim. See Hinkle v. Apfel, 132 F.3d 1349, 1352 (10th Cir.1997) (following Bowen v. Yuckert, 482 U.S. 137, 153, 107 S.Ct. 2287, 96 L.Ed.2d 119 (1987)); see also 20 C.F.R. § 404.1521. Thus, the ALJ adhered to, not diverged from, the findings of Dr. Green.
ALJ’s Assessment of Powell’s Credibility
Powell argues that the ALJ’s analysis of his credibility on certain matters *410was tainted by reliance on factual inaccuracies. We conclude that the alleged inaccuracies are, rather, reasonable characterizations of the record. First, the ALJ noted that Powell did not seek different drugs or treatment for his seizures when, as he alleged, his condition did not improve at all on the medications prescribed. Powell objects to this statement, insisting that he took the three medications prescribed by his treating physician. But this misses the ALJ’s point, which clearly followed upon the examining neurologist’s observations that Powell “has never been on any of the newer and often more effective medications for seizures of this type, of which there are approximately six at this time,” and that “[pjroper management of [his condition] would include ... use of [such] alternative medications if [he] continues to have difficulty that can be documented while Tegretol and Dilantin levels are proven to be therapeutic.” App. II at 156-57.
Powell takes issue with the ALJ’s statement that he had not told his doctors about “feeling almost asleep or other side effects of medications,” id. at 18, consistent with what he testified to at the hearing, id. at 192 (Powell stating that he is “almost asleep all the time now” and would “never be able to function” if he took any more medication). Powell cites two instances early on in his treatment when he told Dr. Udonta that he felt “some fatigue and ‘sleepiness’” and “some fatigue” attributable to the Dilantin, id. at 129, 130, and argues that the ALJ misrepresented the record. There is obviously a large gulf between reporting “some” fatigue or sleepiness to his physician and Powell’s claim at the hearing that he was constantly on the verge of incapacitation. While the ALJ might have been clearer in referring to this divergence, we will not assume a factual misrepresentation by an ALJ when her statement can readily be understood as a reasonable and relevant comment on a discernable discrepancy in the claimant’s account of his condition.
Powell insists the ALJ mischaraeterized the record when she stated that his general complaint of being “in constant pain” voiced to Dr. Green, the examining psychologist who suggested the presence of a mental pain disorder as a result, see id. at 161-62 (also noting Powell rated severity of this pain to “a rather marked degree”), had not been reported by him elsewhere. The unique nature of this complaint led the ALJ to ask about it at the hearing, where Powell said he had a dull headache behind his eyes all of the time and also referred to arthritis in his shoulders. Id. at 200. Powell now ignores his belated and unsubstantiated claim about arthritis and focuses on headaches, noting that he alleged “almost constant headache on left side” in a reconsideration disability report, id. at 89, and that his current (part-time) employer submitted a letter stating Powell “periodically” must leave work due to headaches, id. at 168. Actually, neither of these references is fully consistent with either his complaint to Dr. Green or the account of that complaint he gave at the hearing. In any event, it seems clear from context that the ALJ simply meant Powell never voiced the same broad complaint of constant marked fain to another doctor, which is an inconsistency reasonably to be noted (further, specifically as to headaches, we note Powell often did not mention them and never told a doctor that he had them constantly or on a daily basis).
Finally, Powell contends the ALJ wrongly criticized him for failing to report the frequency of his seizures to his doctors. Powell cites several medical records reciting estimates of the number of seizures he was having. Actually, the ALJ referred to two different types of inconsistency in Powell’s reports of his seizures *411and neither of these is refuted by Powell’s citations to the record. First, the ALJ commented that Powell “has described his seizures in a fairly consistent way, but has been inconsistent in reporting the time of their origin.” Id. at 17 (emphasis added). The latter criticism has substantial support in the record. See, e.g., id. at 175 (“[Powell] reports he began having trouble two years ago [i.e., 1995] with intermittent [seizure] episodes”); id. at 134 (reciting “history of paroxysmal spells since 1991”); id. at 156 (reciting Powell “has had episodes” of seizures “[b]eginning in 1985”). Second, the ALJ observed that Powell’s “reports of the frequency of his seizures are not reported to doctors and are inconsistent with [his] activities.” Id. at 18. The ALJ obviously did not mean that Powell had failed to give any frequency estimates to his doctors—she refers to these at various points in her decision; rather, she was commenting on a substantial discrepancy between Powell’s claim at the hearing that he was having one to four seizures a day and many of his reports to doctors indicating much lower rates on the order of one to four a week, see, e.g., id. at 130, 156, 160.
In sum, Powell’s objections do not warrant any disturbance of the ALJ’s decision under the governing standard of review. And, as we have reached this conclusion within the analytical confines of the ALJ’s rationale of decision, the concerns Powell raises about post hoc justification of administrative action, see generally Sec. & Exch. Comm’n v. Chenery Corp., 318 U.S. 80, 63 S.Ct. 454, 87 L.Ed. 626 (1943), are not implicated by our disposition. Thus, we have no occasion to decide whether the principles of Chenery and its progeny, developed in other administrative review settings, should be mechanically imported into the particular context of social security disability proceedings, see generally Sims v. Apfel, 530 U.S. 103, 108-12, 120 S.Ct. 2080, 147 L.Ed.2d 80 (2000) (citing unique “inquisitorial rather than adversarial” character of social security proceedings as reason for not applying traditional administrative issue-exhaustion rale on judicial review); Sullivan v. Hudson, 490 U.S. 877, 885, 109 S.Ct. 2248, 104 L.Ed.2d 941 (1989) (noting judicial review statute governing social security cases “suggests] a degree of direct interaction between a federal court and an administrative agency alien to traditional review of agency action under the Administrative Procedures Act”). We acknowledge that some other circuits have done so, though without explicit consideration of the distinctive aspects of such proceedings noted by the Court in Sims and Hudson. See, e.g., Golembiewski v. Barnhart, 322 F.3d 912, 916 (7th Cir.2003); Fargnoli v. Massanari, 247 F.3d 34, 44 n. 7 (3d Cir.2001).
The judgment of the United States District Court for the Eastern District of Oklahoma is AFFIRMED.
