Island, for the appellant.

       Before PIETSCH, MEREDITH, and FALVEY, Judges.

       FALVEY, Judge: The appellant, Mureto C. Holmes, through counsel appeals a March 1,
2019, Board of Veterans' Appeals (Board) decision denying a rating above 50% for migraines. Mr.
Holmes's appeal is timely and within our jurisdiction. See 38 U.S.C. §§ 7252(a), 7266(a).
       This matter was submitted to a panel of this Court to address whether the rating criteria for
migraines governed by 38 C.F.R. § 4.124a, Diagnostic Code (DC) 8100, contemplate non-
headache symptoms. We hold that they do. As we explain, because DC 8100 rates migraines, a
broader term than headaches, the DC contemplates more than just headache symptoms. Thus, the
criteria require that VA consider all the symptoms the veteran experiences as a result of his
migraine attacks, and then rate those symptoms based on the frequency, severity, and economic
impact of the attacks. And so, we affirm the Board decision because Mr. Holmes fails to show that
the Board clearly erred in finding that the rating criteria adequately compensate him for his
migraine attacks.
                                         I. BACKGROUND
        Mr. Holmes served in the Army from June 1994 to August 1996. In September 2009, he
sought service connection for migraines, depression, anxiety, and stress. Record (R.) at 2090-92.
In June 2010, a VA regional office (RO) granted service connection for migraine headaches, with
a 50% disability rating, but denied service connection for depression, post-traumatic stress
disorder, and a sleep disorder. R. at 1676-81. In the same rating decision, VA denied service
connection for several other disabilities that are not relevant to this appeal. Mr. Holmes did not
appeal this decision.
        In July 2015, VA requested a medical examination to determine the status of Mr. Holmes's
migraines. At an August 2015 examination, Mr. Holmes reported symptoms including headache
pain, nausea, and sensitivity to light. R. at 1059. That same month, the RO issued a decision
continuing the assigned 50% rating. R. at 993-96. Mr. Holmes disagreed with the 50% rating. R. at
982-83. He noted that he experiences sensitivity to light and blurred vision, and wore sunglasses
as a preventive measure.

appellate process, Mr. Holmes sent in more
documents reflecting that he suffers from light-headedness, mood swings, and nausea, and that his
migraines lead to him experiencing dizziness, depression, and anxiety. R. at 794, 976. In March
2017, Mr. Holmes underwent another VA medical examination, confirming symptoms of head
pain and sensitivity to light. R. at 830-31.
        Following the examination, the RO issued a Statement of the Case continuing denial of a
rating above 50%. R. at 807-28. Mr. Holmes perfected his appeal, thus bringing his case to the
Board. In the decision on appeal, the Board found that Mr. Holmes's 50% rating under DC 8100—
the diagnostic code for migraines—left him adequately compensated. R. at 7. The Board explained
that this DC "contemplate[s] very frequent completely prostrating and prolonged attacks
productive of severe economic inadaptability."

that "any symptoms related to
the [v]eteran's headaches that are productive of economic inadaptability and/or that cause
prostrating attacks are taken into consideration."

at this conclusion by
delving into the meaning of migraines.
        It noted that "a 'migraine' is defined as familial symptom complex of periodic attacks
preceded by prodromal sensory symptoms and commonly associated with irritability, nausea,
vomiting[,] constipation or diarrhea, and photophobia." R. at 8 (citing DORLAND'S ILLUSTRATED
MEDICAL DICTIONARY 1166 (32d ed. 2012)). Based on this understanding, the Board concluded



                                                2
that "[t]he rating criteria for migraines, by [their] very nature, contemplate the various
manifestations of such disability by focusing on the overall functional impairment, rather than a
demonstration of particular symptoms." R. at 8. Thus, it found the veteran's 50% rating was
adequate because it "was assigned based on the severity, frequency, and duration of the symptoms
reported by the [v]eteran and the resulting impairment of earning capacity."

has not specified any particular symptoms that are not contemplated by the relevant
diagnostic criteria, as effects such as dizziness, anxiety, depression, isolation, nausea, etc., all
address the nature of the headaches and effects on employment."

ANALYSIS
        On appeal, the veteran argues that the Board clearly erred in finding that all his symptoms
were contemplated by the rating criteria. Under his reading of the regulation, DC 8100 does not
contemplate non-headache symptoms such as nausea, vertigo, mood swings, sleep impairment,
anxiety, isolation, or depression. He also faults the Board for not considering separate ratings for
those symptoms and argues that this stemmed from the Board abdicating its duty to maximize
benefits.
        In response, the Secretary challenges the factual basis of the appellant's argument. He
disagrees that the Board found that all the symptoms the veteran attributes to his migraines were
caused by the migraines. As the Secretary sees it, the Board only listed symptoms the veteran
reported but did not decide that they are all caused by his migraines. Instead, the Board found that
the symptoms at issue are all contemplated by the rating criteria, which consider whether the
veteran's migraines cause prostrating attacks and then consider the frequency and duration of the
prostrating attacks and whether they lead to severe economic inadaptability. The Secretary backs
the Board's interpretation of DC 8100. Separately, the Secretary argues that the Board could not
award separate ratings for all the alleged symptoms.
                                       A. Legal Landscape
        We begin by addressing whether the Board correctly found that the 50% rating for DC
8100 adequately compensated the veteran. If the Board was correct that this rating adequately
compensated the veteran for his migraines, that would be the end of this matter. Because this is a
question of regulatory interpretation, we begin with the text of the regulation. See Good Samaritan
Hosp. v. Shalala, 

, 409 (1993). If the plain meaning of the regulation is clear from its



                                                 3
language, then that meaning controls and "that is 'the end of the matter.'" Tropf v. Nicholson,

, 320 (2006) (quoting Brown v. Gardner, 

, 120 (1994)). Put another
way, if the regulation is not ambiguous, the "regulation then just means what it means—and the
court must give it effect." Kisor v. Wilkie, 

, 2415 (2019).
        We thus turn to the text of DC 8100, the code that governs disability ratings for migraines.
"With less frequent attacks," a veteran should be awarded a 0% rating. 38 C.F.R. § 4.124a, DC
8100 (2020). "With characteristic prostrating attacks averaging one in 2 months over last several
months," the veteran receives a 10% rating.

attacks occurring
on an average once a month over last several months," a veteran is entitled to a 30% rating.

rating at issue—is awarded "[w]ith very frequent completely prostrating and
prolonged attacks productive of severe economic inadaptability."

previously analyzed the meaning of this DC when we held that DC 8100's
criteria are successive—meaning that each level of the DC requires that the veteran also satisfy the
lower levels. Johnson v. Wilkie, 

, 247 (2018). On our way to that holding, we
defined many terms in this regulation. "'Prostrating' means 'lacking in vitality or will: powerless to
rise: laid low.'"

(citing WEBSTER'S THIRD NEW INTERNATIONAL DICTIONARY OF THE
ENGLISH LANGUAGE UNABRIDGED 1822 (1966)). Thus, we explained that, "[b]ecause DC 8100
specifically governs migraine headaches, the phrase 'characteristic prostrating attacks' plainly
describes migraine attacks that typically produce powerlessness or a lack of vitality."

.
We then explained that the modifier "completely," as used before "prostrating" in the 50% criteria ,
meant that the veteran must be rendered entirely powerless and that "productive of severe
economic inadaptability" means either producing or capable of producing severe economic
inadaptability.

        Putting all this together, we see that the 50% rating for migraines is appropriate with very
frequent, prolonged attacks that render the veteran entirely powerless and either cause or can cause
severe economic inadaptability. This definition does not get us an answer here. To be sure, we can
see that the rating criteria focus on attacks and differentiate between the different levels of
disability based on the frequency, duration, and severity of those attacks, as well as whether they
lead to or could lead to economic inadaptability. The rating criteria say nothing about headaches,
nor do they focus only on the symptom of head pain. In fact, no specific symptoms are listed in
the DC. But if migraines—the thing the veteran experiences during the attacks—refers solely to



                                                  4
headaches, this would mean that the regulation looks only to the severity, duration, frequency, and
economic result of the veteran's headaches. In other words, the regulation would consider only
headaches and not any other symptoms.
       Thus, at its core, this case is about whether headaches and migraines mean the same thing.
DC 8100 lays out the criteria for migraines, but if migraines mean only headaches, the DC just
gives the criteria for headache attacks. And if they do mean the same thing, then the Board erred
when it found that the veteran's rating compensated him for more than headaches. But if migraines
include more than headaches, the Board was on the right track. Thus, we turn to deciding the
meaning of migraines.
                                     B. Defining Migraines
       As with any regulatory interpretation where the terms are not defined in the regulation, we
presume those terms carry their ordinary dictionary meaning. See Moody v. Wilkie, 

, 336 (2018) (per curiam). To this end, the Board used Dorland's Medical Dictionary to define
migraines as "familial symptom complex of periodic attacks preceded by prodromal sensory
symptoms and commonly associated with irritability, nausea, vomiting[,] constipation or diarrhea,
and photophobia." R. at 8. This definition dovetails with other sources.
       For example, a dictionary that straddles the time between when VA first created the rating
schedule with DC 8100 in 1945 and then formally published in the Federal Register in 1964,
defines migraine as "[a] nervous, pathological affection characterized by increasingly severe
headache which is usually confined to one side of the head and is accompanied by nausea, vomiting
and sensory disturbances." Migraine, WEBSTER'S NEW TWENTIETH CENTURY DICTIONARY:
SECOND EDITION UNABRIDGED 1071 (1957); see also 29 Fed. Reg. 6718, 6719 (May 22, 1964)
(explaining the history behind VA's adopting the rating schedule).
       The understanding of a migraine as including more than headaches has continued up to
today. The online version of Merriam-Webster defines migraine as "a condition marked by
recurring moderate to severe headache with throbbing pain that usually lasts from four hours to
three days [and] is often accompanied by nausea, vomiting, and sensitivity to light or sound, and
is sometimes preceded by an aura and is often followed by fatigue." Migraine, Merriam-
Webster.com Dictionary, Merriam-Webster,              https://www.merriam-webster.com/dictionary/
migraine;    see   also    Migraine,     Mayo        Clinic,   https://www.mayoclinic.org/diseases -
conditions/migraineheadache/ symptoms-causes/syc-20360201 (explaining that "[a] migraine can



                                                 5
cause severe throbbing pain or a pulsing sensation, usually on one side of the head. [And is] often
accompanied by nausea, vomiting, and extreme sensitivity to light and sound"). All these sources
reflect that a migraine is a broad term that covers more than headaches.
        This presents an opportune time to explain our reliance on dictionaries and address Mr.
Holmes's concern with the Board's use of Dorland's. Mr. Holmes argues that the Board erred by
relying on a dictionary to conclude that the migraine rating contemplates more than headaches
because this means that the Board made its own impermissible medical determination. See Colvin
v. Derwinski, 

, 172 (1991), overruled on other grounds by Hodge v. West, 

(Fed. Cir. 1998). This is not correct. Neither the Board, nor this Court, is turning to a
dictionary to decide whether something is a symptom of migraines. Instead, we look to a dictionary
to determine whether migraines include more than headaches. To be sure, it would be improper
for the Board or this Court to look at a dictionary or treatise and use that to make a medical decision
about whether a particular symptom results from the veteran's service-connected disability. See
Delrio v. Wilkie, 

, 242 (2019) (noting that VA adjudicators "generally lack the
expertise or competence to opine on medical matters").
        But that's not what's happening here. Our goal is not to replace a medical professional, but
to determine what VA meant when it said that "migraines" "[w]ith very frequent completely
prostrating and prolonged attacks productive of severe economic inadaptability" should be rated
as 50% disabling. 38 C.F.R. § 4.124a, DC 8100 (emphasis added). Did VA simply mean that
headaches with very frequent, prolonged, and prostrating attacks and causing economic
inadaptability should be rated at 50%? Or was VA referring to more than headaches? Answering
this question is no different from what we did in Johnson when we defined the other terms in DC
8100. 

; see also Marbury v. Madison, 

, 177 (1803) ("It is
emphatically the province and duty of the judicial department to say what the law is. Those who
apply the rule to particular cases, must of necessity expound and interpret that rule."); 38 U.S.C.
§ 7261(a)(1) (authorizing    this Court to "decide all relevant questions of law, interpret
constitutional, statutory, and regulatory provisions, and determine the meaning or applicability of
the terms of an action of the Secretary"). Thus, let us then return to our task of interpreting DC
8100.
        Recall that we just confirmed that migraine is a broader term than headache. With this piece
of DC 8100 in place, we break down each element of the 50% rating. First, we have "migraines"—



                                                  6
the thing being rated and which we now know includes symptoms besides simply headaches. Next,
we also already know that the 50% rating requires "very frequent completely prostrating and
prolonged attacks." 38 C.F.R. § 4.124a, DC 8100. Or, in other words, the attacks must be frequent,
prolonged, and render the veteran entirely powerless. Finally, the attacks must result or potentially
lead to severe economic inadaptability. Id.; 

. Putting this together, we
see what VA looks to when it rates migraines and how it differentiates symptoms.
       As we explained, the rating focuses on "attacks." It is the frequency, duration, severity, and
economic impact of these attacks that differentiate the levels of disability in DC 8100. And because
migraines include more than just headaches, we can see that the rating criteria must not be
concerned merely with one symptom—the veteran's headaches, but also other things that he or she
experiences because of migraine attacks. Thus, VA must look at everything the veteran
experiences as a result of migraine attacks and then consider the frequency, duration, severity, and
economic impact of those symptoms. Or as the Board put it, "[t]he rating criteria for migraines, by
[their] very nature, contemplate the various manifestations of such disability by focusing on the
overall functional impairment, rather than a demonstration of particular symptoms." R. at 8.
       The bottom line is that the rating criteria for migraines contemplate all migraine symptoms.
And so, we hold that DC 8100 contemplates more than just headache symptoms and requires that
VA consider all the symptoms the veteran experiences as a result of migraine attacks, and then
rate those symptoms based on the frequency, duration, severity, and economic impact of the
attacks. See 38 C.F.R. § 4.124a, DC 8100. In other words, whatever symptoms the veteran
experiences associated with migraine attacks, VA must consider when assigning a schedular
disability rating. This is much like the severity, frequency, and duration analysis relevant to
evaluating a psychiatric disorder under 38 C.F.R. § 4.130. See Vazquez-Claudio v. Shinseki,

, 116 (Fed. Cir. 2013). The disability levels for psychiatric disorders are
"distinguished from one another by the frequency, severity, and duration of their associated
symptoms."

this reading by asking us not to defer to the Secretary's interpretation—
which agrees with our own reading of the regulation. But we do not defer to the Secretary. We
resolve this case based on the plain language of the regulation, thus leaving no room for ambiguity -
resolving canons or deference to the Secretary's interpretation of his regulation. See 

. Mr. Holmes is also mistaken when he argues that this reading of the regulation



                                                 7
reads out the possibility of additional compensation for manifestations of migraines and the
application of VA's duty to maximize benefits.
       Our reading of the regulation does not foreclose the possibility that a veteran's migraines
could cause or aggravate a separate disability that would then need to be compensated through
other means, such as secondary service connection under 38 C.F.R. § 3.310(a). For instance, if a
manifestation was noted to be constant, as opposed to just during migraine attacks, this may raise
the possibility of a secondary disability. Likewise, if the veteran's migraines go beyond economic
inadaptability and lead to the veteran being unable to secure substantially gainful employment, a
total rating based on individual unemployability remains an option. See 38 C.F.R. § 4.16 (2020).
And of course, the veteran's symptoms may raise extraschedular considerations if they present an
exceptional case with symptoms more severe, frequent, or long-lasting than what is contemplated
in the rating criteria—very frequent, completely prostrating and prolonged attacks, leading to
economic inadaptability. See 38 C.F.R. §§ 3.321 (2020), 4.124a, DC 8100.
       Besides, any difficulty of awarding additional compensation that may result does not render
unreasonable VA's interpretation of the diagnostic code. Recall the rating for psychiatric
disabilities. The Federal Circuit has read § 4.130 to encompass all psychiatric symptoms. See

. Yet there is no question that this does not render
unreasonable the Secretary's rating criteria.
       In the end, we may not strike down a valid interpretation of a diagnostic code simply
because we find its plain text to be less favorable than other diagnostic codes. This Court "may not
review the schedule of ratings for disabilities adopted under section 1155 . . . or any action of the
Secretary in adopting or revising the schedule." 38 U.S.C. § 7252(b). The Federal Circuit has made
clear that, absent a constitutional claim, we are prohibited from reviewing the validity of the rating
schedule. See Wanner v. Principi, 

, 1131 (Fed. Cir. 2004). Thus, even if we found
that the plain language of DC 8100 is less favorable to veterans than other diagnostic codes, we
lack the authority to rewrite it to a more favorable one.
                                  C. Application to Mr. Holmes
       Having found that DC 8100 contemplates more than headaches, we turn to the Board's
decision as applied to Mr. Holmes's case. This ultimately proves a short inquiry.
       At the outset, we agree with Mr. Holmes that "[t]he Board associated several of [his] non-
headache symptoms, including dizziness, anxiety, depression, isolation, and nausea, with his



                                                  8
migraine headaches." Appellant's Br. at 6. 1 The Board laid out the evidence of the veteran's
symptoms that it considered when assigning his rating. R. at 7-8. As part of this analysis, the Board
did not make any unfavorable determinations that the symptoms did not result from appellant's
migraines.

favorable finding that we may not disturb. See 38 U.S.C. § 7261(a)(4)
(permitting review only of "adverse" material findings).
         At the same time, the Board did not find that Mr. Holmes has separate disabilities that are
caused or aggravated by his migraines. Instead, the Board accepted the veteran's statements that
when he has migraines, he experiences symptoms like nausea, dizziness, or "mood swings from
okay, to depressed" and not wanting to be around people. R. at 795. We understand both the
Board's finding and Mr. Holmes's primary position to be that he suffers from feelings of depression
or anxiety associated with his migraines, not that he has separate diagnosed disabilities secondary
to his migraine disability. 2
         After laying out Mr. Holmes's symptoms, the Board found that all the symptoms were
adequately compensated by a 50% rating because the rating is "based on the severity, frequency,
and duration of the symptoms reported by the [v]eteran and the resulting impairment of earning
capacity." R. at 8. We have explained that the Board's conclusion—that the rating criteria
contemplate more than just headaches—was correct. This largely controls the result of this case.
Mr. Holmes focused his argument on fighting the definition used by the Board; he did not explain


         1
          As we explained, it is the role of the factfinder to decide whether something is a symptom of migraines
based on the evidence before it. Our decision should not be read as establishing a list of migraine symptoms; we do
not decide whether something is a symptom of a migraine. Our role is to review that finding. Here, Mr. Holmes agrees
with the Board about what is a symptom of his migraines.
         2
            To the extent that Mr. Holmes may be arguing that the Board erred in failing to consider whether his
migraines cause separate disabilities that may be compensated on a secondary basis, he has not demonstrated that any
error on the part of the Board was prejudicial. See 38 U.S.C. § 7261(b)(2) (requiring the Court to "take due account
of the rule of prejudicial error"); Shinseki v. Sanders, 

, 409 (2009). In his principal brief, he argued only
that, under Saunders v. Wilkie, 

, 1364 (Fed. Cir. 2018), undiagnosed conditions—including vertigo,
mood swings, sleep impairment, anxiety, isolation, and depression—could be compensated as separate disabilities.
But the Court recently held that separate ratings for psychiatric symptoms are not warranted absent a diagnosis that
conforms to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Martinez-Bodon v. Wilkie,

, 404 (2020). Further, Mr. Holmes has identified no evidence, other than his lay assertions, indicating
an association between any diagnosed psychiatric conditions and migraines. And he has not explained how any
undiagnosed non-psychiatric impairments "rise to a level to affect earning capacity." Wait v. Wilkie, __ Vet.App. __,
__, 

, at *6 (Vet. App. Aug. 26, 2020). Rather, he points to diagnostic codes that reference those
non-psychiatric impairments, without demonstrating the severity, duration, and frequency of his own manifestations
of those conditions. Cf.

("Although the appellant may rely generally on VA's regulations to assert that VA
recognizes [certain manifestations] as the types of manifestations that can cause functional impairment in earning
capacity, he must also show that his manifestations are of sufficient severity, duration, and frequency that they effect
his ability to function under the ordinary conditions of life.").



                                                           9
how he prevails if the Board's definition was correct. "[A]s a general rule, our system 'is designed
around the premise that [parties represented by competent counsel] know what is best for them,
and are responsible for advancing the facts and argument entitling them to relief.'" United States
v. Sineneng-Smith, 

, 1579 (2020) (second alteration in original) (quoting Castro v.
United States, 

, 386 (2003) (Scalia, J., concurring in part and concurring in
judgment)).
         In other words, Mr. Holmes does not explain how the alleged symptoms of his migraines
exceed the severity contemplated by the rating criteria. That is, he does not show that the Board
erred by finding that his symptoms are not more severe than "very frequent completely prostrating
and prolonged attacks productive of severe economic inadaptability." 38 C.F.R. § 4.124a, DC
8100. Essentially, Mr. Holmes argued that the Board erred because the regulation considers only
headaches. But, as the regulation considers more than just headaches—it considers all symptoms
of a migraine—Mr. Holmes would have to prove that his symptoms are either more severe,
frequent, or disabling; are longer lasting; or cause greater economic inadaptability than what the
50% rating in DC 8100 contemplates. He has not done so. Yet it is his burden to do so. See Hilkert
v. West, 

, 151 (1999) (en banc) (finding that the appellant bears the burden of
proving error on appeal), aff'd per curiam, 

(Fed. Cir. 2000).
         The closest he gets is to argue that he has symptoms that are not listed in the dictionary
definition used by the Board, thus leaving him uncompensated for those symptoms by the rating
criteria. But he misunderstands what the Board did when it referenced the dictionary. The Board
did not use the dictionary definition to establish an exclusive list of symptoms. Instead, it used that
definition to conclude that DC 8100 "by its very nature, contemplate[s] the various manifestations
of such disability by focusing on the overall functional impairment, rather than a demonstration of
particular symptoms." R. at 8. Thus, we return to the fact that Mr. Holmes has not met his burden
of showing error in the Board decision. His failure to do so leads us to affirm the Board decision
and to leave the limits of DC 8100 to another day. 3

         3
          Because DC 8100 speaks of "attacks" and their frequency, secondary service connection or separate ratings
may be a real possibility when some of a veteran's symptoms are constant. If something is always happening, it may
no longer be reasonably measured by frequency of attacks. Would it simply be a single, long attack? At that point the
Board may need to consider separate ratings or secondary service connection. Mr. Holmes has not argued that his
symptoms cannot be characterized as very frequent and that their incidence is not tied to his migraine attacks. Nor do
we discern clear error on the part of the Board as the veteran described his symptoms in relation to his migraine attacks.
R. at 794-95. This is particularly true when we consider that Mr. Holmes has already been denied service connection



                                                           10
         What's more, his remaining argument—that the Board failed to exhaust all schedular
alternatives before proceeding to an extraschedular analysis—fares no better than his challenge to
the Board's regulatory interpretation. Mr. Holmes relies on our decision in Morgan v. Wilkie,

(2019), to support his argument. 4 In Morgan, we "h[eld] that VA's duty to
maximize benefits requires it to first exhaust all schedular alternatives for rating a disability before
the extraschedular analysis is triggered."

But we also explained that "[t]he Board is not
required to discuss each of these tools in every case, but it must do so when possible schedular
alternatives for rating a disability are either raised by the claimant or reasonably raised by the
record."

schedule must be deemed inadequate before extraschedular
consideration is warranted." Sowers v. McDonald, 

, 478 (2016) (emphasis added).
Thus, if the Board was correct that all of Mr. Holmes's symptoms are adequately contemplated by
the rating criteria, there is nothing for the Board to compensate on an extraschedular basis or
through alternate means.

because Mr. Holmes fails to show error in the Board's conclusion that his
schedular rating was adequate, he cannot prove prejudicial error from the Board's extraschedular
analysis. See 38 U.S.C. § 7261(b)(1) (requiring that when the Court concludes the Board errs, the
Court must "take due account of the rule of prejudicial error"). As Mr. Holmes appears to
recognize, if the Court finds no error in the Board's decision about his schedular rating, the issue
of additional compensation for these symptoms becomes moot and the rule against pyramiding
would kick in to prohibit separate compensation. See Appellant's Reply Brief at 14 (citing
38 C.F.R. § 4.14 (2019)). If the Board correctly found that DC 8100 compensates the symptoms
that he alleges stem from his migraines, the Board had no more compensating left to do. 5

          Neither party has asked us to stay this matter pending the outcome of Long v. Wilkie, U.S. Vet. App. No.
16-1537 (argued Aug. 28, 2019). And we note that Mr. Holmes is represented by the same counsel as Mr. Long.
Because our resolution of this issue is resolved by noncontroversial precedent and the basic principle of the regulatory
framework that extraschedular considerations arise only "where the schedular evaluation is inadequate," 38 C.F.R.
§ 3.321(b)(1), we find it appropriate to resolve this case while Long remains pending. See Smiddy v. Wilkie,

, 355 (2020).

           We stress that separate ratings, secondary service connection, or other schedular and extraschedular tools
remain a viable option to adequately compensate those veterans with migraine symptoms that exceed the severity,
duration, frequency, and economic impact covered by DC 8100. In Mr. Holmes's case, those options were unavailable
because the Board found that all the symptoms are adequately compensated and he has not established erro r in that
finding.

       In the end, we affirm the Board decision. This is because we hold that DC 8100 requires
that VA consider all the symptoms the veteran experiences because of his migraine attacks, and
then rate those symptoms based on the frequency, duration, severity, and economic impact of those
attacks. As Mr. Holmes has not shown that the Board clearly erred in finding that his migraine s
lead to very frequent completely prostrating and prolonged attacks productive of severe economic
inadaptability and that he is thus adequately compensated, he fails to meet his burden on appeal.
See 

. We leave for another day the question of how frequent or severe
a veteran's symptoms must be to fall outside what's contemplated by DC 8100.


                                     III. CONCLUSION
       On consideration of the above and our review of the record, the Board's March 1, 2019,
decision is AFFIRMED.
