    CYNTHIA WINN,                                                                    FILED

    v.
    ON APPEAL FROM THE UNITED
    COMMISSIONER OF SOCIAL                                   STATES DISTRICT COURT FOR THE
    SECURITY,                                                SOUTHERN DISTRICT OF OHIO
    Defendant-Appellee.
    BEFORE:          BOGGS, SILER, and CLAY, Circuit Judges.
    CLAY, Circuit Judge.           Plaintiff Cynthia Winn appeals from the March 31, 2014
    judgment    of    the   district   court   affirming   the   Commissioner   of   Social   Security’s
    (“Commissioner”) finding that Winn was not disabled within the meaning of the Social Security
    Act and was therefore ineligible for disability insurance benefits.         Winn appeals only the
    Commissioner’s denial of disability benefits on the basis of her alleged mental disability.
    For the following reasons, we REVERSE the decision of the district court, VACATE in
    part the decision of the Social Security Administration, and REMAND the case to the Social
    Security Administration for proceedings consistent with this opinion.
    No. 14-3499
    I. BACKGROUND
    A. Procedural History
    On February 19, 2009, Winn filed a Title II application for Social Security disability
    insurance benefits (“DIB”), alleging that she had been disabled since March 3, 2008. The Social
    Security Administration denied Winn’s claim initially and upon reconsideration. Winn requested
    a hearing, which was held on March 22, 2011. Winn testified at the hearing, as did impartial
    vocational expert Brian Womer. Following the hearing, an administrative law judge (“ALJ”)
    determined that Winn was not disabled within the meaning of the Social Security Act.
    Despite finding that Winn suffered from severe physical impairment related to
    degenerative joint disease, the effects of previous ankle surgery, and obesity, the ALJ determined
    that Winn retained the residual functional capacity (“RFC”) to perform sedentary work. With
    regard to Winn’s claimed mental impairment, the ALJ concluded that Winn had failed to meet
    the burden of proving that she suffered from “a mental impairment that has existed at a ‘severe’
    level for a continuous period of at least 12 months.” (R. 6, Certified Administrative Record,
    Page ID # 77.) In reaching this decision, the ALJ determined that the opinion of Winn’s treating
    psychiatrist should not be afforded controlling weight. Since the Appeals Council declined to
    review the ALJ’s decision, this decision represents the Commissioner’s final determination.
    Upon exhausting her administrative remedies, Winn sought judicial review of the
    Commissioner’s decision in the United States District Court for the Southern District of Ohio.
    On January 22, 2014, a magistrate judge issued a report and recommendations, recommending
    that the ALJ’s non-disability finding be vacated. The magistrate judge concluded that the ALJ
    did not adequately consider the opinion of Winn’s treating psychiatrist and failed to recognize
    the “significant amount of evidence indicating Plaintiff has a severe mental impairment.” (R. 14,
    2
    No. 14-3499
    Report and Recommendations, Page ID # 910.) Additionally, the magistrate judge determined
    that “[the ALJ] failed to properly consider any mental limitations in Plaintiff’s RFC.” (Id.) The
    Commissioner filed objections to this report. The district court agreed with the Commissioner,
    and, on March 31, 2014, affirmed the Commissioner’s determination that Winn was not disabled,
    concluding that “the ALJ applied the correct legal criteria and the record as a whole contains
    substantial evidence to support the ALJ’s decision.” (R. 17, Entry and Order, Page ID # 935.)
    Winn timely appealed to this Court.
    B. Factual History
    Winn claims her disability began on March 3, 2008. At that time, she was fifty-three
    years old. She suffers from diagnosed physical and mental impairments. Her physical ailments
    include degenerative joint disease, degenerative disc disease, residual effects of an ankle fracture
    and subsequent corrective surgery, and obesity.           As this appeal challenges the ALJ’s
    determination only as it relates to Winn’s alleged mental disability, her mental health history is
    discussed in greater detail below.
    1. Mental Health Impairments
    Winn reports a long family history of depression, with multiple family members who
    committed suicide. She testified that she was diagnosed as being manic depressive in her
    twenties, and that she was more recently diagnosed as bipolar. With respect to her symptoms,
    Winn reports having erratic mood swings and bouts of depression that cause her to isolate herself
    from other people and to have difficulty getting out of bed and eating. During these bouts of
    depression, Winn stays in her apartment all day, avoids contact with other people, and stops
    maintaining her hygiene (she has gone nearly two weeks without bathing). She testified that she
    hears voices saying negative statements to her, like that she is going to die.
    3
    No. 14-3499
    Winn’s medical records indicate that she has suffered from symptoms including
    insomnia, irritability, agitation, paranoia, anxiety, loss of interest in activities, episodic mood
    swings, difficulty controlling her anger, and occasional suicidal thoughts. Her medical records
    also indicate that the severity of these symptoms waxes and wanes.
    At an initial diagnostic assessment performed on July 8, 2009, Winn was diagnosed with
    depressive disorder and alcohol abuse. She was assigned a Global Assessment of Functioning
    (“GAF”) score of 55 and was referred for counseling and psychotherapy at Daymont Behavioral
    Health Services (“Daymont”).1 Following this assessment, Winn attended regularly scheduled
    appointments with both a psychologist and psychiatrist.        She was prescribed psychotropic
    medication in mid-2009.     As of December 14, 2010, Winn was taking three psychotropic
    medications: Depakote, Lexapro, and Xanax. Treatment notes from Daymont throughout 2009
    and 2010 indicate that Winn continued to suffer from depression and anxiety during this time
    period, despite making progress and experiencing sporadic improvements.
    i. State Agency Evaluations
    On March 5, 2009, prior to beginning her psychological treatment, Winn was examined
    by psychologist Mary Ann Jones at the request of the Bureau of Disability Determination. State
    agency psychologist Kristen Haskins reviewed the record on March 24, 2009 and evaluated
    Winn’s mental functioning capabilities.
    1
    The GAF scale rates an individual’s “overall psychological functioning” from 0 to 100
    at a given moment in time. This scale is meant to reflect an individual’s “psychological, social,
    and occupational functioning on a hypothetical continuum of mental health-illness.” Diagnostic
    and Statistical Manual of Mental Disorders, 4th ed., Text Revision at 34. An individual with a
    score of 51-60 is classified as having “moderate symptoms . . . or moderate difficulty in social,
    occupational, or school functioning.” 
    Id. 4 No.
    14-3499
    Dr. Jones determined that Winn suffers from dysthymic disorder, generalized anxiety
    disorder, and psychological factors affecting her physical condition. She assigned Winn a GAF
    score of 55 and determined that:
    Ms. Winn’s mental ability to relate to others, including fellow workers and
    supervisors, is moderately impaired by her depression, anxiety, and her
    preoccupation with her medical limitations. She would be unable to relate
    sufficiently to coworkers and supervisors on any sustained basis (for two or more
    hours at a time), even to perform simple, repetitive tasks . . . . Ms. Winn’s mental
    ability to understand, remember, and follow instructions is moderately impaired,
    and this is more so by her overall psychological condition than any cognitive
    limitations . . . . Her mental ability to withstand the stress and pressures
    associated with day-to-day work activity is judged as moderately impaired. Ms.
    Winn shows moderate mental limitations in the areas of relating and
    comprehension because of her depression, anxiety, and preoccupation with her
    medical limitations.
    (R. 6, Certified Administrative Record, Page ID # 477.)
    Dr. Haskins reviewed Winn’s record and completed a mental residual functional capacity
    assessment. Dr. Haskins found that Winn was “markedly limited” in her “ability to interact
    appropriately with the general public.” (Id. at 500.) She determined that Winn was “moderately
    limited” in her “ability to complete a normal workday and workweek without interruptions from
    psychologically based symptoms and to perform at a consistent pace without an unreasonable
    number and length of rest periods.” (Id.) She also found Winn to be “moderately limited” in
    her: (1) “ability to respond appropriately to changes in the work setting,” (2) “ability to
    understand and remember detailed instructions;” (3) “ability to carry out detailed instructions;”
    (4) “ability to maintain attention and concentration for extended periods;” and (5) “ability to
    work in coordination with or proximity to others without being distracted by them.” (Id. at 499-
    500.)
    5
    No. 14-3499
    Following her review of the record, Dr. Haskins concluded that Winn “would be able to
    perform [simple repetitive tasks and] follow 1-2 step instructions in a static and non-public
    environment and [without] strict production or time demands.” (Id. at 501.) She also found that
    “[Winn] would be able to interact [with] others minimally and superficially.”           (Id.)     On
    September 15, 2009, state agency psychologist Alice Chambly reviewed the record and affirmed
    Dr. Haskins’ findings.
    ii. Opinion of Treating Psychiatrist Amparo Wee
    Winn began seeing psychiatrist Amparo Wee, M.D. in mid-2010, after her previous
    psychiatrist retired.    In her interrogatories, Dr. Wee concluded that it was not “reasonably
    probable” that Winn “has been capable of functioning at a high enough level” to: (1) “respond
    appropriately to supervision, co-workers and customary work pressures;” (2) “withstand the
    pressure of meeting normal standards of work productivity and work accuracy without
    significant risk of physical or psychological decompensation or worsening of her physical and
    mental impairments;” (3) “sustain attention and concentration on her work to meet normal
    standards of work productivity and work accuracy;” (4) “understand, remember and carry out
    simple work instructions without requiring very close supervision;” (5) “behave in an
    emotionally stable manner;” (6) “maintain concentration and attention for extended periods
    (approximately 2 hour segments);” (7) “respond appropriately to changes in a routine work
    setting;” (8) “get along with co-workers or peers without unduly distracting them or exhibiting
    behavior extremes;” (9) “sustain ordinary routine without special supervision;” (10) “work in
    coordination with, or in proximity to, others without being unduly distracted by them;” or (11)
    “accept instructions and respond appropriately to criticism from supervisors.” (Id. at 702-06.)
    6
    No. 14-3499
    Additionally, Dr. Wee opined that Winn had marked restriction in the activities of daily
    living, marked difficulties in maintaining social functioning, and marked “deficiencies of
    concentration, persistence or pace, resulting in failure to complete tasks in a timely manner (in
    work settings or elsewhere).” (Id. at 706-707.) According to Dr. Wee, Winn’s ability to
    “understand, remember and carry out detailed, but not complex, job instructions” was fair and
    her ability to “understand, remember and carry out simple job instructions” was good. (Id. at
    709.)
    2. Employment History
    Winn has previously worked as a receptionist, a parts sequencer, an auto inventory clerk,
    and a storage rental clerk. Her most recent job was as a parts sequencer at General Motors,
    where she worked for five years until the plant closed in 2008. Following the plant closure,
    Winn unsuccessfully sought employment and received unemployment benefits until April 2010.
    At the time of the ALJ hearing, Winn had no income and was being supported by her family.
    II. DISCUSSION
    A. Standard of Review
    We review a district court’s decision regarding social security benefits de novo. Cole v.
    Astrue, 
    661 F.3d 931
    , 937 (6th Cir. 2011). Appellate review “is limited to determining whether
    the Commissioner’s decision is supported by substantial evidence and was made pursuant to
    proper legal standards.” Id.; see 42 U.S.C. § 405(g). The Commissioner’s decision satisfies the
    substantial evidence requirement if the decision is supported by “‘such relevant evidence as a
    reasonable mind might accept as adequate to support a conclusion.’” Gayheart v. Comm’r of
    Soc. Sec., 
    710 F.3d 365
    , 374 (6th Cir. 2013) (quoting Heston v. Comm’r of Soc. Sec., 
    245 F.3d 528
    , 534 (6th Cir. 2001)).
    7
    No. 14-3499
    B. Legal Standards
    Individuals may be eligible to receive disability insurance benefits from the Social
    Security Administration if they meet certain eligibility requirements. 42 U.S.C. § 423. One such
    requirement is that the individual be “under a disability,” which is defined as an “inability to
    engage in any substantial gainful activity by reason of any medically determinable physical or
    mental impairment which can be expected to result in death or which has lasted or can be
    expected to last for a continuous period of not less than 12 months.” 42 U.S.C. §§ 423(a)(1)(D),
    423(d)(1)(A).
    Administrative law judges follow a five-step inquiry laid out in 20 C.F.R. § 404.1520
    when determining whether to approve or deny disability benefits:
    First, plaintiff must demonstrate that she is not currently engaged in substantial
    gainful activity at the time she seeks disability benefits.
    Second, plaintiff must show that she suffers from a severe impairment in order to
    warrant a finding of disability. A severe impairment is one which significantly
    limits physical or mental ability to do basic work activities.
    Third, if plaintiff is not performing substantial gainful activity, has a severe
    impairment that is expected to last for at least twelve months, and the impairment
    meets a listed impairment, plaintiff is presumed to be disabled regardless of age,
    education or work experience.
    Fourth, if the plaintiff’s impairment does not prevent her from doing her past
    relevant work, plaintiff is not disabled.
    For the fifth and final step, even if the plaintiff’s impairment does prevent her
    from doing her past relevant work, if other work exists in the national economy
    that plaintiff can perform, plaintiff is not disabled.
    Colvin v. Barnhart, 
    475 F.3d 727
    , 730 (6th Cir. 2007) (internal citations and quotation marks
    omitted) (formatting altered for clarity). The review is terminated if the Commissioner makes a
    dispositive finding at any stage of this inquiry. 
    Id. 8 No.
    14-3499
    C. Analysis
    Winn raises two principal challenges to the ALJ’s disability determination. First, Winn
    argues that the ALJ failed to adhere to the treating physician rule by impermissibly discounting
    the opinion of Winn’s treating psychiatrist. Second, Winn argues that the ALJ erred by failing to
    find that Winn suffered from a severe mental health impairment.
    1. The ALJ’s Assessment of Winn’s Treating Psychiatrist
    The ALJ’s determination that the opinion of Winn’s treating psychiatrist should not be
    accorded controlling weight was not based on substantial evidence.
    Under the treating physician rule, an ALJ must give controlling weight to the opinion of a
    claimant’s treating physician if it “is well-supported by medically acceptable clinical and
    laboratory diagnostic techniques and is not inconsistent with the other substantial evidence in
    [the claimant’s] case record . . . .” 20 C.F.R § 404.1527(c)(2). The term “not inconsistent” is
    meant to convey that “a well-supported treating source medical opinion need not be supported
    directly by all of the other evidence (i.e., it does not have to be consistent with all the other
    evidence) as long as there is no other substantial evidence in the case record that contradicts or
    conflicts with the opinion.” Soc. Sec. Ruling 96-2P, 
    1996 WL 374188
    at *3 (July 2, 1996).
    If an ALJ decides that the opinion of a treating source should not be given controlling
    weight, the ALJ must take certain factors into consideration when determining how much weight
    to give the opinion, including: “the length of the treatment relationship and the frequency of
    examination, the nature and extent of the treatment relationship, supportability of the opinion,
    consistency of the opinion with the record as a whole, and the specialization of the treating
    source . . . .” Wilson v. Comm’r of Soc. Sec., 
    378 F.3d 541
    , 544 (6th Cir. 2004).
    9
    No. 14-3499
    Any decision denying benefits “must contain specific reasons for the weight given to the
    treating source’s medical opinion, supported by the evidence in the case record, and must be
    sufficiently specific to make clear to any subsequent reviewers the weight the adjudicator gave to
    the treating source’s medical opinion and the reasons for that weight.” Soc. Sec. Ruling 96-2P,
    
    1996 WL 374188
    at *5 (July 2, 1996). This Court has explained that, in addition to facilitating
    meaningful review, this rule “exists, in part, to let claimants understand the disposition of their
    cases, particularly in situations where a claimant knows that [her] physician has deemed [her]
    disabled and therefore might be especially bewildered when told by an administrative
    bureaucracy that she is not, unless some reason for the agency’s decision is supplied.” 
    Wilson, 378 F.3d at 544
    (internal quotation marks omitted).
    In this case, the ALJ determined that the opinion of Winn’s treating psychiatrist, Dr.
    Wee, should not be given “controlling, or even deferential, weight.” (R. 6-2, ALJ Decision, Page
    ID # 75.) The ALJ’s decision to discount Dr. Wee’s opinion was based on her conclusion that
    Dr. Wee’s opinions are “not borne out by [Winn’s] mental health treatment records.” (Id. at 75.)
    The ALJ went so far as to say that Dr. Wee’s opinion should be “rejected as being less than
    credible” and that “[i]t is entitled to little weight when viewed within the context of the entire
    record.” (Id. at 76.)
    To support this conclusion, the ALJ referenced excerpts from Winn’s mental health
    treatment notes that suggest Winn was “getting out more,” participating in some events, and
    making progress. (Id. at 75.) Namely, the ALJ’s decision quoted the following statements from
    Winn’s treatment notes:
       October [5], 2009 – claimant planning to attend a singles mixer;
       November [23], 2009 – attended the mixer and had a good time;
    10
    No. 14-3499
       November 30, 2009 – making good progress. Went to Alabama with a friend
    for the holiday and had a great time;
       June 8, 2010 – doing much better. Very involved in her church;
       July 13, 2010 – doing well. Feeling better. Appeared well and happy.
    (Id.)
    These half-sentences and phrases paint a misleading picture of Winn’s mental health.
    The ALJ’s skewed depiction improperly disregards significant portions of the specific medical
    notes from which these phrases were excerpted. Viewed in their entirety, these notes clearly
    indicate that Winn continued to suffer from mental ailments. See Hurst v. Sec’y of Health &
    Human Servs., 
    753 F.2d 517
    , 519 (6th Cir. 1985) (“[F]ailure to consider the record as a whole
    undermines the Secretary’s conclusion.”); see also Allen v. Califano, 
    613 F.2d 139
    , 145 (6th Cir.
    1980) (“Substantiality of the evidence must be based upon the record taken as a whole.”). The
    following statements were made within the same treatment notes on the same dates as the phrases
    relied on by the ALJ:
       October 5, 2009 – “Client continues to present with depression,
    agorophobia (mild), tearfullness daily, fatigued frequently . . . . She needs
    to build up her self-esteem.” (R. 6, Certified Administrative Record, Page
    ID # 677.)
       November 23, 2009 – “Client continues to present with depression,
    evidenced by isolation, fatigue.” (Id. at 670.)
       November 30, 2009 – “Client continues to present with depression as
    evidenced by wanting to isolate, fatigue, feeling unmotivated . . . . She
    agreed to 2 social activities weekly. Assigned 2 social activities weekly,
    one can be church.” (Id. at 665).
       June 8, 2010 – “Client continues to present with [symptoms] of depression
    as evidenced by fatigue, lack of motivation.” (Id. at 770.)
    11
    No. 14-3499
       July 13, 2010 – “The client continues to present with [symptoms] of
    agitation, poor stress tolerance . . . Therapist and client processed her
    current stressors and depression.” (Id. at 767.)
    Beyond these selected comments, Winn’s treatment record is laden with notes made by
    Winn’s therapists classifying Winn as depressed and describing the symptoms of her depression
    and anxiety. (See, e.g., 
    id. at 655
    (note from January 29, 2010, explaining that Winn was having
    problems at her church, “continue[d] to present with depression,” and “was upset”); 
    id. at 652
    (note from March 9, 2010: “Client continues to present with [symptoms] of depression as
    evidenced by fatigue, lack of motivation, some agitation . . . . Therapist helped client challenge
    her cognitive distortions . . . . Client agreed to do her 3 activities per week.”); 
    id. at 648
    (note
    from March 30, 2010: “Client continues to present with [symptoms] of depression as evidenced
    by fatigue, lack of motivation, some anhedonia developing . . . . Client said her interests were
    waning for her books and other things she used to love . . . . She feels down, presented as
    depressed, but stable.”); 
    id. at 641
    (note from May 11, 2010: “Client continues to present with
    [symptoms] of depression as evidenced by not bathing in almost 2 weeks, appeared unkempt, a
    lot of fatigue, lack of motivation.”).)
    Nothing in the notes relied on by the ALJ, or in the notes not cited by the ALJ,
    contradicts or conflicts with Dr. Wee’s opinion that Winn’s mental functioning capabilities were
    markedly limited.     The treatment notes indicate that Winn was consistently classified as
    depressed, that she was subject to mood swings, and that the intensity of her depression shifted
    episodically. (See, e.g., 
    id. at 643
    (“The client presents differently from week to week, either
    very depressed or very happy, rarely in the middle.”).) The ALJ emphasized treatment notes
    indicating that “[Winn’s] mental condition showed improvement with appropriate treatment.” (R.
    6-2, ALJ Decision, Page ID # 72.) However, these notes in no way contradict Dr. Wee’s general
    12
    No. 14-3499
    assessment of Winn’s mental health. The notes indicate progress and improvement from some
    previous baseline; they are not inconsistent with the conclusion that Winn’s overall condition
    was such that she suffered from severe mental impairment. In fact, in the final treatment note on
    record before the ALJ, dated January 26, 2011, a therapist indicated that despite Winn’s progress,
    she still experienced “major bouts of depression and can’t always determine the reason for
    these.” (R. 6, Certified Administrative Record, Page ID # 755.)
    Moreover, given the documented episodic nature of Winn’s mental ailments, it is
    unsurprising that she reported some better days and some worse days. It is notable that even
    during her “better” days, Winn’s treatment notes continued to classify her as presenting as
    depressed, anxious, and agitated. By focusing exclusively on instances in which Winn appeared
    to be doing relatively well and by determining (as no pyschiatrist or psychologist had) that Winn
    has only “mild limitations” in her mental functioning, “the ALJ impermissibly substitut[ed] [her]
    own judgment for that of a physician.” McCain v. Dir., Office of Workers Comp. Programs, 58
    F. App’x 184, 193 (6th Cir. 2003). Such reasoning on the part of an ALJ “appears to be
    grounded in a myopic reading of the record combined with a flawed view of mental illness.”
    Boulis-Gasche v. Comm’r of Soc. Sec., 451 F. App’x 488, 494 (6th Cir. 2011) (vacating an ALJ’s
    decision where the ALJ relied on indications of a claimant’s relative improvement in determining
    that no mental impairment existed).
    The ALJ seems preoccupied with discrete instances in which Winn participated in social
    activities, emphasizing Winn’s church attendance, participation in a singles mixer, and two trips.
    However, the ALJ ignores the fact that Winn’s participation in social activities was a prescribed
    part of her treatment. Moreover, Winn’s participation in these activities does not constitute
    substantial evidence that Winn would be able to participate in work activities. “[An] ALJ’s focus
    13
    No. 14-3499
    on the claimant’s ability to do certain activities in discounting the treating source’s opinion does
    not constitute ‘good reasons’ for doing so when the claimant’s testimony and other record
    evidence contradict the ALJ’s finding.” 
    Cole, 661 F.3d at 939
    ; see also Rogers v. Comm’r of
    Soc. Sec, 
    486 F.3d 234
    , 248 (6th. Cir 2007) (finding that activities such as driving, cleaning an
    apartment, caring for pets, reading, exercising, and watching the news “are not comparable to
    typical work activities”).
    Furthermore, “[t]he functional limitations of mental impairments are to be assessed”
    based on which activities the claimant can do “on a sustained basis.” Gayheart v. Comm’r of
    Soc. Sec., 
    710 F.3d 365
    , 377 (6th Cir. 2013) (finding that a claimant’s ability to “visit his aunt
    and uncle,” “receive occasional visits from his neighbor,” and “his ability to accompany his wife
    on [monthly] grocery-shopping trips” do not suggest that he would be able to “interact
    independently and appropriately with others on a sustained basis” and do not contradict the
    contrary opinion of his treating source). Winn’s treatment records do not indicate that she was
    able to successfully participate in the activities identified by the ALJ on a sustained basis. The
    ALJ neglected to consider treatment notes describing that, despite participating in social
    activities at the instruction of her therapist, Winn continued to encounter difficulties in social
    contexts.
    Dr. Wee’s opinion was supported by the opinions of three psychologists who evaluated
    Winn or reviewed her records at the request of the Bureau of Disability Determination. Dr. Jones
    examined Winn on March 5, 2009 and Dr. Haskins reviewed the record on March 24, 2009. As
    previously discussed, both Dr. Jones and Dr. Haskins determined that Winn had moderate levels
    of limitations in her ability to understand, remember, follow instructions, relate to others, and
    withstand the stress and pressure of day-to-day work activity. Dr. Jones concluded that Winn
    14
    No. 14-3499
    “would be unable to relate sufficiently to co-workers and supervisors on any sustained basis (for
    two or more hours at a time), even to perform simple, repetitive tasks.”        (R. 6, Certified
    Administrative Record, Page ID # 477.) Dr. Haskins concluded that Winn would only be able
    “to interact [with] others minimally and superficially.” (Id. at 501.) She also determined that
    Winn would be moderately limited in her “ability to complete a normal workday and workweek
    without interruptions from psychologically based symptoms and to perform at a consistent pace
    without an unreasonable number and length of rest periods.” (Id. at 500.) With regard to Winn’s
    ability to interact appropriately with the general public, Dr. Haskin’s found her to be markedly
    limited. Dr. Chambly reviewed the record and affirmed Dr. Haskin’s conclusions on September
    15, 2009.
    The ALJ ultimately rejected the opinions of these state psychologists as non-
    representative of Winn’s condition following treatment. The invalidity of this rejection will be
    discussed below.     However, for the purposes of determining whether the ALJ erred in
    discounting Dr. Wee’s conclusions, it is relevant that Dr. Wee’s opinion is consistent with the
    opinions of the state psychologists insofar as they identified similar functional limitations at
    degrees of seriousness that would qualify as “severe” for the purpose of determining disability.
    See Soc. Sec. Ruling 85-28, 
    1985 WL 56856
    at *3 (1985) (stating that impairment is considered
    “severe” unless “the [claimant’s] impairment(s) has no more than a minimal effect on his or her
    physical or mental ability(ies) to perform basic work activities”).
    In sum, the ALJ’s decision to discount the opinion of Winn’s treating psychiatrist was not
    supported by substantial evidence. Dr. Wee’s opinion is consistent with other treatment notes in
    the record, which, despite acknowledging that Winn experienced improvement and had “good
    days,” continuously indicated that Winn suffered from depression, mood swings, and anxiety.

    (internal quotation marks omitted). Accordingly, this case will be remanded to the Social
    Security Administration.
    2. The ALJ’s Determination about the Severity of Winn’s Mental Impairment
    The ALJ’s conclusion that Winn did not suffer from a severe mental impairment that
    would limit her ability to perform work activity was not based on substantial evidence and
    constitutes reversible error.
    i.   Severity of Winn’s Mental Impairments
    As was mentioned above, an impairment is considered “severe” unless “the [claimant’s]
    impairment(s) has no more than a minimal effect on his or her physical or mental ability(ies) to
    perform basic work activities.” Soc. Sec. Ruling 85-28, 
    1985 WL 56856
    , at *3 (1985). We have
    previously observed that the claimant’s burden of establishing a “severe” impairment during the
    second step of the disability determination process is a “de minimis hurdle.” Higgs v. Bowen,
    
    880 F.2d 860
    , 862 (6th Cir. 1988). “Under [this] prevailing de minimis view, an impairment can
    be considered not severe only if it is a slight abnormality that minimally affects work ability
    regardless of age, education, and experience.” 
    Id. In this
    case, the ALJ concluded that Winn failed to establish that she suffered from a
    disability caused by her mental health impairments because she did not demonstrate that she had
    a “mental impairment that has existed at a ‘severe’ level for a continuous period of at least
    12 months.” (R. 6-2, ALJ Decision, Page ID # 77.) In so determining, the ALJ rejected the
    opinions of three state psychologists as being “non-representative of the claimant’s longitudinal
    mental functioning capabilities” because Winn’s medical records indicate that she “responded
    16
    No. 14-3499
    favorably to psychological counseling and the use of psychotropic medication,” which were
    prescribed only after the state assessments. (Id.)
    First and foremost, as was discussed above, the ALJ’s conclusion is explicitly
    contradicted by the assessment of Dr. Wee, Winn’s treating psychiatrist. Dr. Wee determined
    that Winn suffered from significant functional limitations over a year after she began taking
    psychotropic medications. By concluding that the improvement experienced by Winn rendered
    her no longer “severely” impaired, the ALJ impermissibly substituted her judgment for that of
    Winn’s treating psychiatrist. See McCain, 58 F. App’x at 193 (“[A]n ALJ is not free to set his
    own expertise against that of a physician who presents competent evidence.”) (internal quotation
    marks omitted).
    Moreover, the ALJ’s determination that the opinions of the state psychologists should be
    discounted as “non-representative of [Winn’s] longitudinal mental functioning capabilities” is
    inconsistent with Winn’s medical records as a whole. Winn’s treatment records strongly suggest
    a continuous severe mental impairment.         On May 11, 2010, over a year after her first
    assessments by the state psychologists, a treatment note describes that Winn “continue[d] to
    present with [symptoms] of depression as evidenced by not bathing in almost 2 weeks, appeared
    unkempt, a lot of fatigue, lack of motivation.” (R. 6, Certified Administrative Record, Page ID #
    641.) A treatment note from March 30, 2010 reports: “Client said her interests were waning for
    her books and other things she used to love . . . . She feels down, presented as depressed, but
    stable.” (Id. at 648.) Despite stating that Winn was “making definite progress,” an April 13,
    2010 medical note describes the persistence of Winn’s mood swings: “The client presents
    differently from week to week, either very depressed or very happy, rarely in the middle.” (Id. at
    643). On January 26, 2011, nearly two years after the state psychologists’ assessments, Winn’s
    17
    No. 14-3499
    therapist observed that “[Winn] still has major bouts of depression and can’t always determine
    the reason for these.” (Id. at 755.)
    Although Winn’s medical records suggest that her treatment was helping her, the ALJ
    had no basis for the determination that Winn’s mental impairments had subsided to the point that
    they were no longer severe. Most of the comments in Winn’s notes regarding her improvement
    are relative rather than absolute. The ALJ repeated multiple times that Winn’s notes indicated
    she was “getting out more” and had “made a lot of progress.” (R. 6-2, ALJ Decision, Page ID #
    72, 75 and 76.)     However, what matters for the purposes of Winn’s functional limitation
    determination is Winn’s overall state, not the mere fact that treatment was helping. Nothing in
    the notes cited by the ALJ supports the conclusion that Winn’s degree of improvement from her
    previous baseline rendered her only mildly impaired. See Boulis-Gasche, 451 F. App’x at 494.
    (“The ALJ made no inquiry into the degree of improvement, or from what baseline Plaintiff had
    improved. Under the ALJ’s logic, any improvement in one’s mood, regardless of how small and
    from what level the individual improved, would defeat a claim of mental impairment. This
    cannot be so.”)
    The opinions of the three state psychologists in March and September of 2009 and that of
    Dr. Wee in August 2010, as well as a large volume of medical notes in the interim period
    indicating the persistence of Winn’s mental impairments, are uncontradicted by any other
    evidence in the record. The ALJ’s determination that Winn did not suffer from a ‘severe’ mental
    impairment is therefore not based on substantial evidence.
    ii.   Reversible Error
    An ALJ’s failure to find a severe impairment where one exists may not constitute
    reversible error where the ALJ determines that a claimant has at least one other severe
    18
    No. 14-3499
    impairment and continues with the remaining steps of the disability evaluation. Maziarz v. Sec’y
    of Health & Human Servs., 
    837 F.2d 240
    , 244 (6th Cir. 1987). This rule is predicated on the
    notion that the ALJ “properly could consider claimant’s [non-severe impairments] in
    determining whether claimant retained sufficient residual functional capacity to allow [her] to
    perform substantial gainful activity.” 
    Id. In this
    case, despite concluding that Winn did not have
    a severe mental impairment at step-two of the ALJ’s five-step sequential evaluation process, the
    ALJ determined that Winn suffered from a severe physical impairment. Having determined that
    Winn suffered from such an impairment, the ALJ continued to step-four of the evaluation
    process before determining that Winn was not disabled.           However, the ALJ’s step-four
    determination regarding Winn’s RFC did not consider Winn’s mental impairments in a
    meaningful way. Accordingly, as the magistrate judge recommended, we are unable to conclude
    that the ALJ’s error “falls within the parameters of Maziarz.”             (R. 14, Report and
    Recommendations, Page ID # 910.) This error therefore requires reversal.
    III. CONCLUSION
    For the foregoing reasons, we REVERSE the decision of the district court, VACATE in
    part the decision of the Social Security Administration, and REMAND the case to the Social
    Security Administration for proceedings consistent with this opinion.
