DAT P.TRAN,

ACTING SECRETARY OF VETERANS AFFAIRS, APPELLEE.

On Appeal from the Board of Veterans' Appeals

(Argued May 21, 2020 Decided January 26, 2021)

Zachary M. Stolz, with whom Brittani L. Howell and April Donahower, were on the brief, 

all of Providence, Rhode Island, for the appellant.

Jacqueline Kerin, with whom James M. Byrne, General Counsel; Mary Ann Flynn, Chief

Counsel; and Anna Whited, Deputy Chief Counsel, were on the brief, all of Washington, D.C., for

the appellee.

Before BARTLEY, Chief Judge, and MEREDITH and TOTH, Judges.

BARTLEY, Chief Judge: Veteran Ronald V. Garner appeals through counsel an 

August 31, 2018, Board of Veterans' Appeals (Board) decision denying service connection for 

obstructive sleep apnea (OSA), including as secondary to service-connected major depressive 

disorder (MDD). Record (R.) at 3-8. This appeal is timely, and the Court has jurisdiction to review 

the Board decision pursuant to 38 U.S.C. §§ 7252(a) and 7266(a). This matter was referred to a 

panel of the Court, with oral argument, to address what is necessary to reasonably raise the issue 

of obesity as an intermediate step toward service connection in the causal chain between the

veteran's service-connected disabilities and the claimed disability, OSA. This is an issue of first 

impression, and today we provide guidance to the Board for adjudication of these types of claims. 

The Court concludes that the record in this case does not reasonably raise the issue of 

obesity as an intermediate step toward secondary service connection. Nevertheless, because the

Board relied on examinations that were inadequate to allow the Board to make a fully informed 

decision as to any relationship between the OSA and the veteran's service-connected MDD, we 

will set aside the August 2018 Board decision and remand the matter for further development and 

readjudication consistent with this decision.

I. FACTS

Mr. Garner served on active duty in the U.S. Air Force from June 1972 to May 1992. R. at 

1410. He reports that between 1972 and 1973, he worked 12-hour shifts, 7 days a week on the 

flight line. R. at 3201. 

In December 1972, Mr. Garner sought treatment for pain and swelling in both knees. R. at 

2619. He was diagnosed with chondromalacia and ordered to light duty. Id. In September 1976, 

Mr. Garner injured his left knee playing football. R. at 2623. The following month, he still had 

effusion in his left knee and was diagnosed with prepatellar bursitis. R. at 2626. In November 

1979, Mr. Garner injured his right ankle playing basketball. R. at 2610, 2612-13. At that time, he 

was diagnosed with a ligament/tendon strain. R. at 2613. 

In November 2010, Mr. Garner filed a claim for service connection for various disabilities, 

including left knee, right ankle, and left shoulder disabilities. R. at 3877. In December 2011, a VA 

regional office (RO) granted service connection for, among other things, left knee and right ankle 

disabilities, assigning a 10% disability evaluation for each condition. R. at 3222-38. 

In June 2012, Mr. Garner subsequently sought VA mental health treatment for severe 

chronic depression, anxiety, labile mood swings, disillusionment, and social withdrawal. R. at 

3201. He continued to experience pain and stiffness in his left ankle, knee, and shoulder, and 

expressed that the resulting limitations from these conditions impacted his mood: "I was once a lot 

more physically active, but now it depresses me[;] . . . because of my [ankle, knee, and shoulder 

disabilities,] I can no longer do the things that made my life enjoyable." Id. Noting that Mr. Garner 

was in the process of applying for compensation benefits for his mood disorder, id., the VA 

psychologist opined that Mr. Garner's psychiatric condition was "more likely than not" related to 

his service-connected disabilities, R. at 3202. 

In October 2012, Mr. Garner filed a claim for service connection for a mood disorder as 

secondary to his service-connected musculoskeletal conditions. R. at 3199. In September 2013, a 

VA examiner diagnosed an Axis I mood disorder, not otherwise specified (NOS), and under Axis 

III, noted hypertension.1 R. at 1182-87. In May 2014, the RO granted service connection for a 

 

1 The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), which was in effect 

in 2013, used a multiaxial system for classifying mental disorders. Axis I referred to clinical disorders and other 

conditions that may be a focus of clinical attention, while Axis III referred to general medical conditions "that are 

potentially relevant to the understanding or management of the individual's mental disorder." DIAGNOSTIC AND 

STATISTICAL MANUAL OF MENTAL DISORDERS 27, 29 (4th ed., text revision 2000). The current version, the DSM-5, 

uses a nonaxial system. See DIAGNOSTIC AND STATISTICAL MANUAL OF MENTAL DISORDERS 16 (5th ed., 2013).

mood disorder, NOS, as secondary to service-connected left shoulder osteoarthritis, and assigned 

a 50% evaluation. R. at 2452-57. 

In November 2013, Mr. Garner sought treatment for a sleep disorder. R. at 2516-18. He 

stated that his wife and daughter described that he would fall asleep and stop breathing. R. at 2517. 

He reported that he would frequently fall asleep while resting in the evening, and his wife would 

observe him gasping and choking upon waking. Id. Mr. Garner described waking up frequently 

during the night and experiencing dry mouth in the mornings. Id. The physician noted that Mr. 

Garner's symptoms were suggestive of OSA and ordered a polysomnogram for a definitive 

diagnosis. Id. Testing revealed mild OSA and poor sleep efficiency. R. at 2042. 

In February 2014, Mr. Garner filed a claim for service connection for OSA, R. at 2570-72, 

which the RO denied in June 2014, R. at 2395-96. Mr. Garner timely filed a Notice of 

Disagreement (NOD), asserting his belief that his OSA was brought on by his service-connected 

mood disorder. R. at 2327-28. 

In September 2015, a VA examiner diagnosed OSA. R. at 2031-32. The examiner opined 

that the veteran's OSA was less likely than not proximately due to or the result of a serviceconnected condition, noting that "[e]xtensive review of medical literature[] revealed that mood 

disorder is not one of the known risk factors" for OSA. R. at 2034. Instead, he indicated that the 

veteran's risk factors for OSA included "his age, male gender and obesity." Id. 

In November 2015, a VA mental health examiner noted the veteran's diagnosis of 

unspecified depressive disorder. 2 R. at 1922. The examiner noted that complaints of pain in 

multiple sites, including the left shoulder, both feet, and both hands, as well as hypertension and 

OSA, were relevant to the understanding or management of the veteran's mental health disorder. 

Id. Mr. Garner arrived at the appointment in a hospital wheelchair, but was able to ambulate into 

the office using a cane. R. at 1926. 

That same month, the RO issued a Statement of the Case (SOC) continuing to deny service 

connection for OSA as secondary to a mood disorder NOS. R. at 1979-2000. Mr. Garner timely 

appealed the RO's decision, stating that as a result of his OSA he was falling asleep at the wheel 

and that his breathing would stop. R. at 1824. He noted that his symptoms were worsening and 

 

2 Although Mr. Garner was previously diagnosed with mood disorder NOS, that diagnosis does not appear 

in the DSM-5; accordingly, his diagnosis was updated in 2015 to unspecified depressive disorder. See R. at 1922. 
4

that his activity was limited as a result of his OSA. Id. Two months later, he submitted a statement 

in support of claim reiterating that his condition was worsening. R. at 1813.

In August 2016, Mr. Garner underwent a mental health diagnostic assessment through VA 

for the continued management of his psychiatric condition, then diagnosed as MDD.

3 R. at 1610-

18. The physician noted that Mr. Garner continued to have periods of depression, "perpetuated and 

precipitated by pain and other medical issues." R. at 1611. The physician indicated that the veteran 

"struggle[s] with pain and associated physical limitations," id., and recorded Mr. Garner's report 

of severe pain that he rated a 6 or 7 out of 10, R. at 1614. The physician noted that pain interfered 

with the veteran's normal daily activities and resulted in decreased physical capacity. Id. Finally, 

the physician documented the veteran's body mass index (BMI) of 31, which is obese. R. at 1615. 

Mr. Garner declined to participate in the MOVE! (Managing Overweight Veterans Everywhere) 

weight management/health promotion program. R. at 1615, 1617.

In June 2017, a VA mental health examiner noted Mr. Garner's report that pain related to 

his knees, shoulders, wrists, and back impacted his mood on a daily basis. R. at 912. The examiner 

recorded Mr. Garner's statement: "I used to be a strong individual and well controlled, but now 

feel worthless. I feel broken. I'm not half the man I used to be." R. at 914. The examiner indicated 

that Mr. Garner's diminished concentration and lack of interest in doing anything were 

compounded by his physical limitations. Id. The examiner noted that the veteran walked with an 

unsteady gait and at a slow pace, with use of a walking cane. R. at 916. 

In November 2017, a VA examiner opined that the veteran's OSA was less likely than not 

aggravated beyond its natural progression by his service-connected mood disorder. R. at 574-75. 

The examiner noted that, while Mr. Garner's mood disorder contributes to his insomnia, "it has no 

effect on the etiology . . . or progression of his sleep apnea[,] which is due to collapse of the 

oropharyngeal tissue." R. at 575. The RO issued a Supplemental SOC continuing to deny 

entitlement to service connection for OSA as secondary to MDD. R. at 620-36. 

In August 2018, the Board issued the decision currently on appeal. R. at 3-8. The Board 

reviewed the evidence of record and concluded that there was no link between the claimed 

disability and the veteran's service or service-connected MDD. R. at 8. The Board stated that the 

September 2015 and November 2017 examiners made it clear that Mr. Garner's OSA was not 

 

3 By 2016, the veteran's psychiatric diagnosis had been changed to MDD. See R. at 1616. 
5

related to service or to his service-connected MDD; rather, OSA was caused by a collapse of the 

oropharyngeal tissue. R. at 7. The Board noted the September 2015 examiner's statement that mood 

disorder is not one of the known risk factors for the development of OSA. R. at 6. Instead, the 

2015 examiner opined that Mr. Garner's age, male gender, and obesity were all risk factors. R. at 

7. The Board also relied on the 2017 examiner's opinion that, although the veteran's MDD 

contributed to insomnia, it had no effect on the etiology or progression of OSA. R. at 7. The Board 

acknowledged the 2017 examiner's note that the veteran's claustrophobia was impairing 

compliance with the continuous positive airway pressure (CPAP) machine, but determined that 

this was not aggravation of OSA. Id. Accordingly, the Board denied Mr. Garner's claim for service 

connection for OSA as secondary to service-connected MDD. Id. This appeal followed.

II. ANALYSIS

A. Reasonably Raising Obesity as an Intermediate Step 

Toward Secondary Service Connection4

1. The Parties' Arguments

Mr. Garner argues that the Board erred in failing to consider the reasonably raised theory 

that his service-connected MDD, right ankle, or left knee conditions caused or aggravated his 

obesity, which in turn caused or aggravated his OSA. Appellant's Brief (Br.) at 15-20. He points 

to evidence that his service-connected orthopedic (knee and ankle) conditions reduced his physical 

activity levels and to evidence that his service-connected MDD left him feeling "broken and 

worthless," lacking motivation to engage in activities that might promote fitness or weight loss. 

Id. at 16 (citing R. at 914). Mr. Garner argues that this evidence, when viewed in conjunction with 

the September 2015 examiner's opinion that the veteran's obesity was a risk factor for the 

development of OSA, see R. at 2034, as well as evidence that he gained weight over the same 

period, was sufficient to reasonably raise the theory that his OSA was proximately related to the 

service-connected conditions, with obesity as the intermediate step between service-connected 

MDD, right ankle, and left knee conditions and OSA. Appellant's Br. at 16-17. As support for his 

contentions, Mr. Garner cites to Alexander v. Shulkin, No. 16-0799, 2017 WL 2333080 (Vet. App. 

May 30, 2017), a nonprecedential memorandum decision that remanded the appeal for the Board 

 

4 Although the Court ultimately remands on a different theory of entitlement, that does not render moot the 

appellant's arguments that the Board also erred with respect to thistheory of entitlement and the Court will thus,in its 

discretion, address the parties' argumentsin this regard. See Quirin v. Shinseki, 22 Vet.App. 390, 395 (2009).
6

to address a reasonably raised theory of secondary service connection based on obesity as an 

intermediary step between the veteran's claimed disability and service-connected disabilities.

Appellant's Br. at 19. 

The Secretary responds that the record evidence marshaled by Mr. Garner to support such 

a theory of service connection is "attenuated at best." Secretary's Br. at 13. He argues that there is 

no evidence connecting Mr. Garner's weight gain of approximately 12-20 pounds over the period 

of 25 years following service to any of his service-connected disabilities. Id. Finally, the Secretary 

notes that Alexander was not a precedential decision. Id. at 15. To the extent that the Court might 

be persuaded by Alexander, the Secretary distinguishes the facts of this case, observing that Mr. 

Alexander experienced extremely severe mobility problems due to his service-connected 

conditions. Id. at 14-15 (citing Alexander, 2017 WL 2333080, at *3).

2. Governing Law & Application to this Appeal

Establishing service connection generally requires medical or, in certain circumstances, lay 

evidence of (1) a current disability; (2) in-service incurrence or aggravation of a disease or injury; 

and (3) a link between the claimed in-service disease or injury and the present disability. 

Romanowsky v. Shinseki, 26 Vet.App. 289, 293 (2013). In evaluating a veteran's claim, the Board 

is required to consider all theories of entitlement to VA benefits that are either raised by the 

claimant or reasonably raised by the record. DeLisio v. Shinseki, 25 Vet.App. 45, 53 (2011) ("[T]he 

Secretary generally must investigate the reasonably apparent and potential causes of the veteran's 

condition and theories of service connection that are reasonably raised by the record or raised by 

a sympathetic reading of the claimant's filing."); Robinson v. Peake, 21 Vet.App. 545, 555 (2008) 

(holding that the Board errs when it fails to adequately address all issues expressly raised by the 

claimant or reasonably raised by the evidence of record), aff'd sub nom. Robinson v. Shinseki, 

557 F.3d 1355 (Fed. Cir. 2009). 

In Barringer v. Peake, the Court concluded that it has jurisdiction to determine in the first 

instance whether the record reasonably raised a particular issue. 22 Vet.App. 242, 244 (2008). 

Although in other cases, including Robinson and Lynch v. Wilkie, we articulated that whether an 

issue is reasonably raised is essentially a factual question, the Board in those cases did not assess 

whether a pertinent issue was raised, and the Court proceeded to determine in the first instance 

whether the issue was reasonably raised before the Board. Lynch v. Wilkie, 30 Vet.App. 296, 304-

06 (2018); Robinson, 21 Vet.App. at 552-57. Notably, the U.S. Court of Appeals for the Federal 
7

Circuit (Federal Circuit) in Robinson acknowledged the Court's approach in upholding that 

decision. 557 F.3d at 1362. Because in Mr. Garner's case the Board did not address whether obesity 

as an intermediate step toward secondary service connection was reasonably raised, the approach 

that the Court took in Lynch and Robinson applies, and the Court will determine in the first instance 

whether the issue of obesity as an intermediate step was reasonably raised to the Board.

5

In January 2017, VA's Office of General Counsel issued a precedential opinion addressing 

the status of obesity for the purposes of establishing entitlement to service connection. VA. Gen. 

Coun. Prec. 1-2017 (Jan. 6, 2017) [hereinafter G.C. Prec. 1-2017]; see 38 U.S.C. § 7104(c) 

(providing, in relevant part, that the Board is bound by precedential decisions of VA's Office of 

General Counsel); see Walsh v. Wilkie, 32 Vet.App. 300, 305 (2020) (noting that "because 

[General Counsel] opinions lack the formalities of notice-and-comment rulemaking, the Court 

defers to them in accordance with their 'power to persuade'" (quoting Wanless v. Shinseki, 618 F.3d 

1333, 1338 (Fed. Cir. 2010)). The General Counsel noted that obesity per se is not a disease or 

injury, and therefore, may not be service connected on a direct basis. G.C. Prec. 1-2017 at 1, ⁋ 1. 

However, the General Counsel determined that "[o]besity may be an 'intermediate step' between a 

service-connected disability and a current disability that may be service connected on a secondary 

basis under 38 C.F.R. § 3.310(a)." Id. at 2, ⁋ 5. 

The General Counsel's opinion addressing obesity as an intermediate step provides 

guidance for the adjudication of such claims; this guidance received the Court's endorsement as to 

the soundness of its analysis in Walsh. 32 Vet.App. at 305-07. The opinion discusses the 

hypothetical case of a veteran whose service-connected back disability causes obesity due to lack 

of exercise; the obesity in turn leads to hypertension. G.C. Prec. 1-2017 at 9, ⁋ 14. To decide 

entitlement to secondary service connection in such a case, the General Counsel advises that the 

Board would be required to resolve (1) whether the service-connected back disability caused the 

veteran to become obese; (2) if so, whether obesity, as a result of the service-connected disability,

was a substantial factor in causing the claimed secondary disability, hypertension; and (3) whether 

hypertension would not have occurred but for obesity caused by the service-connected back 

disability. Id. at 9-10, ⁋15. Affirmative answers to these questions would support a determination 

 

5 Under a deferential standard of review, any implied Board conclusion that obesity as an intermediate step 

toward secondary service connection was not reasonably raised would be determined not to be clearly erroneous, and 

the end result here would not differ. 
8

of service connection for hypertension secondary to the veteran's back disability. In Walsh, we 

held that the General Counsel opinion requires the Board to consider aggravation in addition to 

causation in the context of claims where a theory of secondary service connection, with obesity as 

an intermediate step, is explicitly raised by the veteran or reasonably raised by the record.

32 Vet.App. at 307. Taken together, our holding in Walsh and the General Counsel's opinion

illustrate the mechanism by which obesity as an intermediate step could result in secondary service 

connection; however, they do not provide guidance regarding what factual circumstances would

give rise to claims for secondary service connection via this theory.

Although the Court has not addressed that issue in a precedential decision, a survey of 

single-judge decisions reveals factors that the Court has considered relevant to this determination. 

Review of a broad array of factual circumstances here will help to illuminate the type and quality 

of evidence that may be sufficient to reasonably raise a theory of secondary service connection via 

obesity as an intermediate step. See generally William L. Reynolds & William M. Richman, The 

Non-Precedential Precedent—Limited Publication and No-Citation Rules in the United States 

Courts of Appeals, 78 COLUM.L.REV. 1167, 1190 (1978) ("[T]he accumulation of a large number 

of routine decisions on a discrete point may suggest to courts, practitioners, or scholars that 

problems exist in that area, problems that may require doctrinal reform."). To that end, we note 

that considerations that could give rise to a reasonably raised theory of secondary service 

connection with obesity as an intermediate step may include, but are not limited to, mobility 

limitations or reduced physical activity as a result of a service-connected physical disability (in 

particular, orthopedic conditions or chronically painful conditions);

6

reduced physical activity or 

inability to follow a course of exercise or diet as a result of service-connected mental disability;

7

side effects of medication (e.g., weight gain), where the medication is prescribed for a serviceconnected disability;

8

treatise evidence suggesting a connection between all or some combination 

of obesity, service-connected disability, and the claimed condition;

9

lay statements by a veteran 

 

6

See, e.g., Davis v. Wilkie, No. 17-1481, 2018 WL 6204582, at *2 (Vet. App. Nov. 29, 2018); Lanham v. 

Shulkin, No. 16-2666, 2018 WL 480539, at *6 (Vet. App. Jan. 19, 2018); Alexander, 2017 WL 2333080, at *2-4.

7

See, e.g.,Milliken v. Wilkie, No. 18-4155, 2019 WL 4584251, at *2-3(Vet. App. Sept. 23, 2019); Simonsen 

v. Wilkie, No. 18-2724, 2018 WL 9669512, at *2-3 (Vet. App. Sept. 25, 2018).

See, e.g., Dodson v. Wilkie, No. 19-0921, 2020 WL 425131, at *4 (Vet. App. Jan. 28, 2020).
9

attributing weight gain or obesity to the service-connected disability;

10 and statements by treating 

physicians or medical examiners attributing weight gain or obesity to the service-connected

disability.11

We do not identify these factors in an attempt to limit any reasonably raised theory of 

obesity as an intermediate step to a circumscribed set of circumstances. Rather, we note that these 

considerations encompass a diverse array of factual situations, but share a critical commonality: 

in each case, there is some evidence in the record which draws an association or suggests a 

relationship between the veteran's obesity, or weight gain resulting in obesity, and a serviceconnected condition. Cf. Robinson, 21 Vet.App. at 553 (noting that the duty to assist is triggered 

when "some evidence . . . 'indicates' that the disability 'may be associated' with . . . service" 

(quoting 38 U.S.C. § 5103A(d)(2)(B))). 

In Mr. Garner's case, no such relationship can be found in the record. Although there is 

evidence demonstrating Mr. Garner has gained weight since service and is now considered obese, 

compare R. at 2676 (1986 service treatment record indicating the veteran's weight of 203 pounds), 

with 3321 (2010 treatment record indicating veteran's weight of 220 pounds and BMI of 31.57), 

and 1649 (2016 orthopedic treatment note indicating veteran's weight of 234.3 pounds and BMI 

of 31), there is no evidence linking his service-connected orthopedic conditions and resulting 

mobility limitations to weight gain, see R. at 3201 (2012 outpatient treatment note reflecting the 

veteran's report that he reduced his physical activity due to his service-connected medical 

conditions, but with no mention of his weight or of weight gain), 1618 (2016 primary care 

treatment note indicating the veteran regularly exercised for 60 minutes twice weekly). 

Similarly, no evidence connects the veteran's service-connected depressive disorder to 

behaviors associated with weight gain (e.g., difficulties following a course of diet or exercise, or 

overeating). There are no lay statements by the veteran associating his service-connected 

conditions specifically with weight gain or obesity. See R. at 914 (June 2017 VA Disability 

Benefits Questionnaire with the veteran's lay statement associating his depressive disorder with a 

general loss of motivation); see also R. at 2328 (October 2014 NOD with the veteran's lay 

statement associating his OSA with a variety of psychiatric symptoms). And in the veteran's 

 

10 See, e.g.,Lanham, supra note 6.

11 See, e.g.,Milliken and Simonsen, both supranote 7.
10

extensive treatment records, none of the medical providers of record note any connection between 

the veteran's service-connected conditions and weight gain or obesity. See, e.g., R. at 1615 (August 

2016 treatment record reflecting the veteran's referral to the MOVE! program). We hold that, 

where, as here, the record reflects only incidental references to the veteran's weight or weight gain, 

the evidence of record is insufficient to reasonably raise the theory of secondary service connection 

via obesity as an intermediate step.

B. Adequacy of the September 2015 and November 2017 VA Examinations as to the 

Relationship between MDD and OSA

1. The Parties' Arguments

Mr. Garner argues that neither the September 2015 nor the November 2017 VA 

examinations are adequate for adjudication purposes, and that the Board erred when it relied on 

those examinations. Appellant's Br. at 8-15. Mr. Garner specifically contends that the examinations 

are inadequate because each examiner failed to provide sufficient rationale for the conclusion that 

his service-connected MDD did not aggravate his OSA. Appellant's Br. at 8-15. The Secretary 

disputes these contentions and urges the Court to affirm the Board decision. Secretary's Br. at 4-

11.

2. Adequacy of VA Medical Examinations

When the Secretary undertakes to provide a veteran with a VA medical examination or 

obtain an opinion, he must ensure that the examination or opinion provided is adequate. Barr v. 

Nicholson, 21 Vet.App. 303, 311 (2007). A VA medical examination or opinion is adequate "where 

it is based upon consideration of the veteran's prior medical history and examinations," Stefl v. 

Nicholson, 21 Vet.App. 120, 123 (2007), "describes the disability . . . in sufficient detail so that 

the Board's 'evaluation of the claimed disability will be a fully informed one,'" id. (quoting Ardison 

v. Brown, 6 Vet.App. 405, 407 (1994)), and "sufficiently inform[s] the Board of a medical expert's 

judgment on a medical question and the essential rationale for that opinion," Monzingo v. Shinseki, 

26 Vet.App. 97, 105 (2012) (per curiam). See also Acevedo v. Shinseki, 25 Vet.App. 286, 293 

(2012) ("[A]n adequate medical report must rest on correct facts and reasoned medical judgment 

so as [to] inform the Board on a medical question and facilitate the Board's consideration and 

weighing of the report against any contrary reports."); Nieves-Rodriguez v. Peake, 22 Vet.App. 

295, 301 (2008) ("[A] medical examination report must contain not only clear conclusions with 

supporting data, but also a reasoned medical explanation connecting the two."). Of particular 
11

relevance here, a medical examination or opinion that fails to address whether a service-connected 

disability aggravated the claimed disability is inadequate to inform the Board on the issue of

secondary service connection. El-Amin v. Shinseki, 26 Vet.App. 136, 140 (2013).

The Court reviews the Board's determination as to the adequacy of a medical examination 

or opinion under the "clearly erroneous" standard of review set forth in 38 U.S.C. § 7261(a)(4). 

See D'Aries v. Peake, 22 Vet.App. 97, 104 (2008) (per curiam). "A factual finding 'is "clearly 

erroneous" when although there is evidence to support it, the reviewing court on the entire evidence 

is left with the definite and firm conviction that a mistake has been committed.'" Hersey v. 

Derwinski, 2 Vet.App. 91, 94 (1992) (quoting United States v. U.S. Gypsum Co., 333 U.S. 364, 

395 (1948)).

The Board must support its material determinations of fact and law with adequate reasons 

or bases. 38 U.S.C. § 7104(d)(1); Pederson v. McDonald, 27 Vet.App. 276, 286 (2015) (en banc); 

Allday v. Brown, 7 Vet.App. 517, 527 (1995); Gilbert v. Derwinski, 1 Vet.App. 49, 56-57 (1990). 

To comply with this requirement, the Board must analyze the credibility and probative value of 

evidence, account for evidence it finds persuasive or unpersuasive, and provide reasons for its 

rejection of material evidence favorable to the claimant. Caluza v. Brown, 7 Vet.App. 498, 506 

(1995), aff'd per curiam, 78 F.3d 604 (Fed. Cir. 1996) (table).

3. Aggravation and Secondary Service Connection

This Court has explicitly rejected the "permanent worsening" standard in the context of 

claims for secondary service connection of a non-service-connected injury or disease, holding that 

"any additional impairment of earning capacity—in non-service-connected disabilities resulting 

from service-connected conditions, above the degree of disability existing before the increase—

regardless of its permanence" is compensable. Ward v. Wilkie, 31 Vet.App. 233, 239 (2019); see 

38 U.S.C. §§ 1110, 1131; Allen v. Brown, 7 Vet.App. 439, 448 (1995) (en banc). As the Federal 

Circuit noted in Saunders v. Wilkie, 886 F.3d 1356, 1363 (Fed. Cir. 2018), "disability" under 

section 1110 "refers to the functional impairment of earning capacity, not the underlying cause of 

said disability."

Here, the Board summarized the examination reports and concluded that the VA opinions 

carried "significant weight" and that the examiners "made it clear" that the veteran's serviceconnected MDD did not aggravate the OSA. R. at 7. The Board did not expressly discuss its 

reasons for finding the VA examinations adequate. Rather, the Board, in relying on these 
12

examinations, implicitly found that they were adequate. In other words, the Court is able to discern 

the Board's reasons from its discussion of the relative probative value. The Court disagrees with 

the Secretary that the Board's reliance on the 2015 and 2017 examinations was appropriate. See

Secretary's Br. at 4-11.

These opinions provide no insight into the relevant inquiry, which is whether serviceconnected MDD aggravated any functional impairment associated with the veteran's OSA. See 

Ward, 31 Vet.App. at 239. Indeed, the Board's summary reveals, and the Secretary concedes, that 

the September 2015 opinion fails to address aggravation at all: "[E]xtensive review of medical 

literature[] revealed that mood disorder is not one of the known risk factors for development of 

[OSA]. In the case of the [v]eteran, his risk factors include[] his age, male gender[,] and obesity." 

R. at 6 (quoting R. at 2034 (emphasis added)); see Secretary's Br. at 11. This language focuses on 

the etiology of the veteran's OSA, rather than any potential relationship between the OSA and the 

service-connected MDD. See El-Amin, 26 Vet.App. at 140. The Board explained that the 

November 2017 examiner acknowledged that there is a relationship between the veteran's MDD 

and insomnia, but the Board's summary reflects that she similarly focused on the etiology of OSA: 

"'[The veteran's] mood disorder [is] contributing to his insomnia[. H]owever, it has no effect on 

the etiology and[/]or progression of sleep apnea which [is] due to [collapse] of the oropharyngeal 

tissue.'" R. at 7 (quoting R. at 575). The focus on the underlying cause of the OSA—in this case, 

the collapse of the oropharyngeal tissue—fails to illuminate whether the veteran's MDD results in 

any additional functional impairment associated with the OSA. See Saunders, 886 F.3d at 1363; 

Ward, 31 Vet.App. at 239.

Therefore, the Court concludes that the Board clearly erred in finding the VA examinations 

adequate to adjudicate the claim. See D'Aries, 22 Vet.App. at 104; Ardison, 6 Vet.App. at 407 

(holding that the Board errs when it relies on an inadequate medical examination). Consequently, 

the Court holds that remand is warranted for a VA examiner to address whether the veteran's 

service-connected MDD caused a functional increase in the severity of his OSA. See Tucker v. 

West, 11 Vet.App. 369, 374 (1998) ("Generally, where the Board has incorrectly applied the law, 

failed to provide an adequate statement of reasons or bases for its determinations, or where the 

record is otherwise inadequate, a remand is the appropriate remedy.").

In accordance with Kutscherousky v. West, 12 Vet.App. 369, 372-73 (1999) (per curiam 

order), the Court will not preclude Mr. Garner on remand from presenting to the Board the theory 
13

of service connection for OSA as secondary to his service-connected conditions, with obesity as 

an intermediate step. That theory of service connection was expressly raised before this Court and 

the Board is therefore obligated to address it. See DeLisio, 25 Vet.App. at 53; Robinson, 

21 Vet.App. at 553. He may also submit any additional arguments and evidence, including any 

additional arguments he made to this Court; the Board must consider any such evidence or 

argument submitted. See Kay v. Principi, 16 Vet.App. 529, 534 (2002). The Court reminds the 

Board that "[a] remand is meant to entail a critical examination of the justification for the [Board's] 

decision," Fletcher v. Derwinski, 1 Vet.App. 394, 397 (1991), and must be performed in an 

expeditious manner in accordance with 38 U.S.C. § 7112.

III. CONCLUSION

Upon consideration of the foregoing, the August 31, 2018, Board decision is SET ASIDE, 

and the matter is REMANDED for further development and readjudication consistent with this 

decision.
