The Pathology of Borderline Personality Disorder

One of the most challenging psychological disorders for a therapist to treat and among the most resistant to therapy, Borderline Personality Disorder features a number of pathological symptoms including suicidal and parasuicidal ideation, impulsivity, aggression, dysphoria, sensitivity to abandonment, identity disturbance, instability, and angry affect (Grube, 2007). These symptoms present themselves with varying degrees of severity depending upon the patient’s type and level of BPD dysfunction. In a 1968 behavioral study of ego functions, clinical psychologists Roy Grinker, Beatrice Werble, and Robert Drye conducted cluster analysis research to identify four distinct types of patients afflicted with Borderline Personality Disorder. According to their findings, these four subgroups comprising BPD appear to occupy a continuum of decreasing severity on the border between psychotic and neurotic psychopathology. Among all four subgroups, leading features of BPD are “stable instability” (Schmideberg, 1959), “panneurosis”’ “pananxiety”, and “pansexuality” (Knight, 1953). Residing nearest the psychotic border, the BPD Type I subgroup displays features such as quasi-psychotic thought, manipulative suicide efforts, and countertransference difficulties (Zanarini et al., 1990). Type II is characterized by a pervasive pattern of instability within interpersonal relationships. Typically, these Type II patients display several dysfunctional behaviors such as self-mutilation, excessive demands/entitlement, and expressions of concern about abandonment/engulfment and annihilation (Zanarini et al., 1990), in their effort to avoid real or imagined abandonment, separation, loss, or rejection. Type III BPD sufferers show a generalized lack of personal identity, appearing to be immensely challenged at maintaining a stable or consistent sense of themselves as individuals, tending to borrow an identity from others. Chessick (1987) noted a “well-hidden poverty of genuine emotional relationships behind an attractive and personable social façade” (p.532). Type IV Borderline patients – exhibiting various traits indicating countertransference difficulties and treatment regressions (Zanarini et al., 1990) – make up the subgroup closest to the neurotic border (Gabbard, 2005). The borderline patient’s suffering is a relatively stable and enduring condition (Chessick, 1979). Often, a BPD sufferer’s emotional dysregulation leads to an uncontrollable outward volatile affect. Such a sudden shift in affect typically reflects disillusionment with a love object, and indicates the patient’s expectation of impending abandonment. Impulsivity is another characteristic signpost of the disorder. Paul, Schroeter, Dahme, and Nutzinger, 2002 found that typical expressions of impulsivity on the part of the BPD patient include binge eating, self-mutilation, substance abuse, unsafe sex and reckless driving (Zanarini et al., 2007). The patient with BPD often dramatically changes career goals, values, sexual identity, and friends (Gabbard, 2005). While in a crisis of instability a patient may inexplicably quit a job, withdraw socially, and isolate entirely. Such an impulsive and chaotic temperamental display leads to anxiety, guilt, and self-loathing for which the patient may choose to engage in high-risk or self-harming behavior in order to feel relief. These patients are known to have chronic suicidal ideation and often engage in self-harm through acts of cutting or burning (Blatt & Levy, 2003; Clarkin, et al., 2006). The BPD patient who uses cutting, burning, food, drugs, alcohol or other self-injurious behavior may obtain at least temporary pseudo-relief from feelings of self-hatred, lassitude, emptiness, and seemingly intolerable loneliness. All too often impulsive marriages and divorces, unexpected pregnancies and abortions, the perpetual starting and stopping of jobs and academic careers, spoiled successes, and blighted relationships coalesce and contribute to the failure of a promising life and even suicide (Blatt & Levy, 2003; Clarkin, et al., 2006; Lilienfeld, 2012; Linehan, et al., 2006; Wenzel, et al., 2006).
