Interconnection between biological abnormalities in borderline personality disorder: use of the Bayesian networks model.

There is agreement in that strengthening the sets of neurobiological data would reinforce the diagnostic objectivity of many psychiatric entities. This article attempts to use this approach in borderline personality disorder (BPD). Assuming that most of the biological findings in BPD reflect common underlying pathophysiological processes we hypothesized that most of the data involved in the findings would be statistically interconnected and interdependent, indicating biological consistency for this diagnosis.

Neurologic soft signs in borderline personality disorder.

Objective: Borderline personality disorder is a disabling and dramatic psychiatric condition. To date, its pathophysiology remains unclear. Scientific evidence seems to have found underlying, nonfocal, central nervous system dysfunction in borderline personality disorder.

Is the biological nature of depressive symptoms in borderline patients without concomitant Axis I pathology idiosyncratic? Sleep EEG comparison with recurrent brief, major depression and control subjects.

The relationship between borderline personality disorder (BPD) and the affective disorders is controversial, and we have previously compared BPD and major depression (MD) with endocrinological measures and sleep electroencephalography (S-EEG). We have also compared BPD, MD and recurrent brief depression (RBD) using endocrine tests. We have proposed that depressive symptoms in BPD might have a biological substrate that is distinct from those in depressive illness without comorbid BPD.

Biological nature of depressive symptoms in borderline personality disorder: endocrine comparison to recurrent brief and major depression.

Borderline personality disorder (BPD) often shows depressive symptoms and their biological nature albeit extensively discussed remains controversial. The knowledge of this nature seems essential as it could imply key therapeutic strategies. We have found BPD and major depression (MD) not to share biological abnormalities.

Changes in height and motor performance relative to peak height velocity: A mixed-longitudinal study of Spanish boys and girls.

Longitudinal changes in stature and motor performance were studied in an adolescent sample of 36 boys and 53 girls. Peak height velocity (PHV) was determined in 28 boys and 38 girls using non-smoothed polynomials. The estimations of PHV and the age-at-PHV are, respectively, 11.
