Justification for separating schizotypal and borderline personality disorders.

Siever and Gunderson (1979) have questioned the decision to separate Schizotypal Personality Disorder from Borderline Personality Disorder in DSM-III. The justification for this separation rests not on genetic evidence, but rather on the relative independence of the behavioral characteristics of two dimensions that up to now have both been referred to with the appellation "borderline." We believe that this separation provides the tools with which investigators may usefully study the interaction of genetic and environmental factors as they relate to personality and the major psychiatric disorders. The benefits of this separation are already apparent in that research investigators are now using two terms to describe different phenomena, when previously they were using the single term borderline. Proposed diagnostic criteria for Schizotypal Personality Disorder and Borderline Personality Disorder are appended.

Genetic Susceptibility to the Environment Moderates the Impact of Childhood Experiences on Psychotic, Depressive, and Anxiety Dimensions.

BACKGROUND AND HYPOTHESIS: Gene-by-environment (GxE) studies in psychosis have exclusively focused on negative exposures. However, evidence supports the resilience-enhancing effect of positive factors on psychosis outcome. The Differential Susceptibility (DS) model proposes that common genetic variants may confer not only disproportionate responsiveness to negative environments, but also greater sensitivity to positive, resilience-enhancing conditions. This study is the first to apply the DS model to the expression of subclinical psychosis, employing polygenic risk scores of environmental sensitivity (PRS-ES). PRS-ES were hypothesized to moderate, in a DS manner, associations between childhood adversity and psychosis, affective, and anxiety dimensions in young adults. An exploratory goal examined whether PRS for psychotic-like experiences (PRS-PLE) also showed DS patterns. STUDY DESIGN: PRS, schizotypy, PLE, depression, anxiety, and childhood adversity ratings were obtained for 197 nonclinical young adults. LEGIT software for testing competitive-confirmatory GxE models was employed. STUDY RESULTS: Results largely supported DS: Individuals high on PRS-ES showed increased subclinical psychosis, depression, and anxiety if they had experienced elevated childhood adversity, and lower symptoms if exposed to low levels of adversity as compared with those with low PRS-ES. Similarly, PRS-PLE moderated the effect of adversity on PLE, positive schizotypy, and depression following the DS model, but only PRS-ES moderation on PLE survived statistical correction. CONCLUSIONS: Our results suggest that genetic DS to the environment is relevant to psychosis, depression, and anxiety. Current debates on reconceptualization of genetic "risk" and resilience may benefit from this insight that support optimistic views on preventative efforts for early detection and intervention.

Behavioral toxicity. Neuroleptic-induced paradoxical behavioral toxicity in young borderline schizoprenics.

9 young borderline schizophrenics who developed an acute paradoxical behavioral toxicity as a reaction to the initiation of antipsychotic medication are described. The dynamics, the psychological issues as well as some possible psychopharmacological interactions are discussed. The risk of behavioral toxicity should not be overlooked or underestimated and the occurrence of this reaction must be carefully differentiated from other drug-induced reactions.

[The borderline syndrome - a sign of our times].

In conclusion, I would like to say until about 30 to 40 years ago, the patients we saw in our clinical practices presented mainly mono-symptomatic disturbances. Now the picture tends to be multi-symptomatic. It is possible that stronger Victorian influences on ego disciplines were responsible for the mono-symptomatic pattern; in any case, at present, the ego-self boundaries seem weakened, more "permissive", yielding and permeable and this may account for the more multi-symptomatic picture.

Borderline schizophrenia: evidence of its validity.

Borderline schizophrenia is held to be a valid entity that should be included in the DSM-III. It is a chronic illness that may be associated with many other symptoms but is best characterized by perceptual-cognitive abnormalities. It has a familial distribution and a genetic relationship with schizophrenia. The term schizotypal personality is an acceptable alternative to borderline schizophrenia, but given the apparent genetic relationship with schizophrenia, and given that we are dealing with a vulnerability to episodic symptoms more than personality traits, we prefer the older term.

Assessing vulnerability to schizophrenia or manic-depression in borderline states.

In a discussion of the article on genetic determinants of borderline conditions by Siever and Gunderson, a phenotypic continuum between pure schizotypal and pure affective conditions is postulated. Many "borderline" cases are seen as attenuated forms of schizophrenia, schizoaffective psychosis, or manic-depression. A Venn diagram illustrates differences among syndromes described by Gunderson, Kernberg, Spitzer, and Klein ("hysteroid dysphoria"). Evidence is presented suggesting that Gunderson's borderline syndrome contains more schizotypal individuals than Kernberg's, whereas hysteroid dysphoria is nearer the affective pole of the continuum. A second diagram illustrates how the strength and nature of the genetic factors vary according to the syndrome.

Is borderline a distinct entity?

There is no agreement in American psychiatry as to whether borderline should be regarded as a distinct entity. A review of the major viewpoints in the field reveals that borderline is variously used to designate: (1) a clinical disorder distinguishable by behavioral criteria; (2) a milder form of schizophrenia; (3) a nonspecific term encompassing several atypical affective disorders; (4) a psychostructural distinction. When the St. Louis approach to diagnostic validity is used as a guideline, the conclusion reached is that available data do not weigh conclusively for or against borderline's status as an independent entity. In particular, borderline, as defined by several investigators, appears distinct from schizophrenia, but requires further delimitation from the affective disorders.

Genetic determinants of borderline conditions.

Evidence about the genetic determinants for borderline conditions is reviewed. The research data are too limited and the diagnostic practices followed in existing studies are too varied to allow firm conclusions to be drawn. Thus, the need for new studies starting with well-defined samples of borderline patients is clear. Previous work implicates genetic factors in the etiology of at least some borderlines, but it is unclear that borderlines by any definition will, as a group, have uniformly strong and specific genetic determinants. With further research, partially overlapping subgroups might be defined on the basis of careful examination of borderline patients' clinical characteristics and family histories. Such characterization could have potential clinical value since there may be subgroups of borderlines who respond differently to various psychopharmacologic treatments (Klein 1975) or to exploratory versus ego supportive psychotherapy (Stone 1977). Characterizations based on genetic considerations may have their limitations, since the genetics of these disorders probably involve complex interactions of a variety of factors that may be more or less specifically related to other major diagnostic groups.

Correlations between psychiatric diagnosis and some quantitative EEG variables.

Several methods of quantitative analysis were applied to the left parietal 'resting' EEGs of 48 nonpatient controls and 90 undrugged psychiatric inpatients. Patient and control groups, matched for age and sex, differed as follows: (a) Mean frequency was lower and frequency variability was greater in the total patient group than in controls. (b) Mean amplitude was higher and mean frequency lower in chronic schizophrenics than in controls; the amplitude differences were contributed mainly by female patients. (c) Amplitude and frequency means of nonpsychotic patients were intermediate between those of chronic schizophrenics and controls. (d) Mean amplitudes were greater and frequency variability was less in neurotics than in controls.

The borderline syndrome: evolution of the term, genetic aspects, and prognosis.

"Borderline" has been used to designate conditions intermediate between psychosis and neurosis, analyzability and nonanalyzability; also, for dilute or questionable schizophrenia. Contemporary usage inclines toward patients with manic-depressive heredity, although borderlines are still etiologically heterogeneous. Various subtypes are outlined, each responsive to a particular method of psychotherapy or pharmacotherapy. If drug-abuse or antisocial tendencies are absent, prognosis is ofter favorable.

A follow-up study of 29 borderline psychotic children 5 to 20 years after discharge.

Twenty-nine children who during 1956 through 1970 were hospitalized for borderline psychosis were followed up in 1975. Twelve of them had received inpatient psychiatric treatment for 1-3 years. Seventeen were sent home for local, nonspecific help. At follow-up 67% of the treated group were no longer considered psychotic, compared with 70% of the untreated group. The two groups differ somewhat in a series of parameters, the treated group showing more severe psychopathological symptoms. The differences do not reach significant levels. No useful prognostic criteria were obtained from the study. The prognosis seems to be much better than for other types of psychosis in children.

Two reviews of the literature on borderlines: an assessment.

The author discusses Liebowitz's (1979) and Rieder's (1979) reviews of current issues regarding the diagnosis of borderline patients. He cites the need for further research examining the basic characteristics of the borderline syndrome. He also recommends that greater attention be directed toward defining subtypes of the syndrome. The author believes that a combination of the descriptive approach of Gunderson and Kolb (1978) and his own psychostructural approach (Kernberg 1977) would prove fruitful.
