    Debra SPARKS, Plaintiff-Appellant, v. Carolyn W. COLVIN, Acting Commissioner of Social Security, Defendant-Appellee.
    No. 14-2325.
    United States Court of Appeals, Eighth Circuit.
    Submitted: Feb. 20, 2015.
    Filed: March 5, 2015.
    Frederick S. Spencer, Mountain Home, AR, for Plaintiff-Appellant.
    Michael McGaughran, Kendall Morrison Rees, Assistant Regional Counsel, Social Security Administration Office of General Counsel Region VI, Dallas, TX, for Defendant-Appellee.
    
      Before LOKEN, COLLOTON, and KELLY, Circuit Judges.
   PER CURIAM.

Debra Sparks appeals the district court’s order affirming the denial of disability insurance benefits and supplemental security income. For reversal, Sparks argues that the Administrative Law Judge (ALJ) erred in his determination, because he failed to find that (1) her severe impairments included borderline intellectual functioning and (2) her mental impairment met Listing 12.05C. Following careful review of the parties’ submissions and the record before us, we conclude that the doctrine of collateral estoppel precludes Sparks from relitigating whether her mental impairment met Listing 12.05C. See Hardy v. Chater, 64 F.3d 405, 407 (8th Cir.1995). We further conclude that substantial evidence in the record as a whole supports the ALJ’s findings regarding the credibility of Sparks’s subjective complaints, and the severity of her impairments. Accordingly, we affirm the district court’s judgment. See 8th Cir. R. 47B. 
      
      . . The Honorable Erin L. Setser, United States Magistrate Judge for the Western District of Arkansas, to whom the case was referred for final disposition by consent of the parties pursuant to 28 U.S.C. § 636(c).
