Roy Kirby applied for disability insurance benefits and supplemental security income under the Social Security Act. 42 U.S.C. §§ 423, 1382. An administrative law judge (“ALJ”) of the Social Security Administration denied his application, concluding that he does not suffer from a severe impairment. The district court reversed and remanded for entry of an award of benefits, and the Commissioner of Social Security now appeals. We reverse and remand for entry of judgment for the Commissioner.
I.
Kirby asserts that he is disabled because of hand tremors and psychiatric illness. In 2001, he had a hearing before an ALJ, who found that he was not disabled because his impairments were not severe. Kirby petitioned the Appeals Council for review and submitted a psychiatric evaluation by a consulting physician, Dr. Bruce Harry, as new evidence. The Appeals Council denied review, and Kirby sought judicial review. The district court reversed and remanded to the Commissioner, instructing him to develop and evaluate the record more fully and to give further consideration to Dr. Harry’s report. The Commissioner did not appeal that decision, and it is not before us.
After the remand from the district court, a different ALJ conducted a second hearing. Kirby testified that he experienced tremors in both hands, and that the tremors were more severe on the right side. Kirby stated that his “hand keeps at a steady pace of shaking” that “never stops.” (A.R.465). He also testified that he suffered from at least seven seizures per day, some of which caused him to lose control of his arms, and some of which caused his entire body to convulse.
The ALJ declined to accept Dr. Harry’s opinion, and concluded that Kirby’s case was “full of exaggerations by the claimant, and dubious medical diagnoses.” (Id. at 283). He found that Kirby suffered from a “mild right upper extremity tremor,” but that Kirby’s physical impairments were controlled by medication, and were not severe enough to prevent him from maintaining a normal work schedule. (Id. at 284, 286). The ALJ also found that Kirby’s psychiatric problems, including “possible mild dysth[y]mia,” did not significantly limit his ability “to think, understand, communicate, concentrate, get along with other people, and handle normal work stress.” (Id. at 285-86). The ALJ found that Kirby had only “slight abnormalities” that did not “significantly limit[] the performance of any basic work activities.” (Id. at 283). In terms of “mental functioning,” the ALJ applied 20 C.F.R. § 404.1520a, which describes a “special technique” for evaluating claims of mental impairment, and determined that Kirby had “no more than a minimal limitation in his ability to do basic work activities.” (Id. at 285). For these reasons, the ALJ found that Kirby’s impairments were not severe, and that he was therefore not disabled.
After the Appeals Council denied review, Kirby sought review in the district court. The court concluded that the ALJ gave insufficient weight to Dr. Harry’s report and to Kirby’s testimony about his limitations. The court reversed and remanded for entry of an award of benefits, and the Commissioner appeals that decision.
We review the district court’s decision
de novo. Leckenby v. Astrue,
II.
The Commissioner uses a five-step evaluation to determine if a claimant is disabled.
Id.
at 754; 20 C.F.R. § 416.920(a)(4). Step two of the evaluation states that a claimant is not disabled if his impairments are not “severe.”
Simmons,
We conclude that ample evidence supported the ALJ’s conclusion that Kirby’s hand tremors were not severe. There was substantial evidence that Kirby exaggerated or invented his physical ailments, and that any genuine impairments were slight. Kirby underwent several rounds of diagnostic testing to determine the cause of the tremors, all of which produced normal results. Dr. Ravinder Arora, a consulting physician, submitted a report stating that the tremor “seem[ed] to disappear ... when the patient was not paying any attention.” (A.R.243). Several other doctors also contradicted Kirby’s claim that the tremors “never stop[ped],” and noted that the tremors were absent or diminished when Kirby was distracted or when a doctor first entered the room. (Id. at 168, 241, 307). Based on his examination and the medical records, Dr. Arora concluded that the “tremors are intentional and are wiUful.” (Id. at 248).
The ALJ had additional reasons to doubt Kirby’s credibility about his physical impairments. Kirby testified that he had at least seven seizures a day, and that these either left him without control of his arms, or caused his entire body to convulse. The ALJ noted that “[n]o one has ever actually witnessed one of these alleged seizures.” (Id. at 284). Kirby reported that he experienced seizures when he was hospitalized in 2005, but no member of the hospital staff observed them, and tests indicated that none occurred. (Id. at 304, 366). The ALJ also found it “incre-dibl[e]” that Kirby experienced multiple daily seizures, presumably without warning, but that he still drove a car once a week, as he testified. (Id. at 284, 465).
Whatever Kirby’s actual physical impairments, substantial evidence supported the ALJ’s conclusion that they were not severe. Dr. Arora stated that Kirby’s tremors were “[m]inimal,”
(id.
at 243), which was consistent with the ALJ’s observation that the tremors were not noticeable during the hearing.
See Johnson v. Apfel,
Substantial evidence also supported the ALJ’s finding that Kirby did not suffer a significant impairment because of his psychiatric illness. Kirby’s claims of psychiatric problems have always been vague. His initial disability form did not claim a psychiatric basis for disability, and merely stated that his hand tremors might be caused by “pantic or anxioux” [sic ]. (A.R. at 102, 105). Perhaps his most specific claim is that mental problems affect his memory. The medical evidence for this claim is inconclusive, with memory tests producing opposite results. In 2000, Kirby achieved a perfect score on two memory
Kirby offered little evidence of any other mental impairment. The ALJ observed that Kirby “has never had any formal treatment by a psychiatrist, psychologist, or other mental health professional over any long-term basis, which he presumably would have if he were ... mentally disturbed.” (Id. at 285). At the hearing, Kirby “displayed no obvious signs of depression, anxiety, memory loss, or other mental disturbance.” (Id.). Dr. Arora opined that while Kirby may have suffered from depression, his “[cjalculation, recall, comprehension, repetition, judgment, and behavior were normal,” and that he “could follow commands.” (Id. at 243). This opinion conflicts with Dr. Harry’s view that Kirby could not perform even “simple, repetitive tasks under the stresses inherent to a competitive environment.” (Id. at 423).
It is the function of the ALJ to weigh conflicting evidence and to resolve disagreements among physicians.
See Estes v. Barnhart,
We thus do not agree with the district court that the ALJ gave insufficient weight to Dr. Harry’s report and to Kirby’s testimony about his limitations. Substantial evidence in the record as a whole supports the ALJ’s conclusion that Kirby’s physical and mental impairments were slight, and that they did not significantly limit his ability to perform basic work activities. The ALJ plainly believed that Kirby’s impairments had no more than a minimal effect on his ability to work, and this conclusion is supported by the record.
See Henderson v. Sullivan,
For these reasons, the judgment of the district court is reversed, and the case is remanded with instructions to enter judgment for the Commissioner.
