"A preliminary but growing body of evidence supports the existence of biological substrates in personality disorders. Based on a review of the literature, the article deals with the major biological markers: genetic, cognitive, biochemical, electrophysiological and organic markers, of schizotypal and borderline personality disorders. In addition, the article compares these findings in these two types of pathological personality. In the field of genetics, we notice several indices in favour of a relationship between schizotypal personality disorder (SPD) and chronic schizophrenia. In contrast, in borderline personality disorder (BPD), indices were lacking for such a relationship between this disorder and one of the axis I diagnosis, or a clear genetic transmission. In the field of cognitive tests, we can note in both SPD and BPD, that the abnormalities which would be at the level of temporal and frontal lobes, may be implicated in the observable cognitive troubles in these two disorders. In the field of neurobiochemistry, the dopaminergic and serotonergic systems seem to be implicated in the etiology of SPD while several data point out the fact that several neurotransmitter systems (dopaminergic, serotonergic, noradrenergic and cholinergic) seem to be involved in the etiology of BPD. Finally, in the field of electrophysiology, we notice that some of these tests observed in SPD (smooth pursuit eye movements, evoked potentials, modification of the electrodermic response) seem reinforcing the relationship between SPD and schizophrenia while those observed in BPD seem reinforcing either a relationship between BPD and depression (sleep studies), or a relationship between BPD and schizophrenia (evoked potentials, smooth pursuit eye movements)."Pharmacological Treatment

"Treatment with divalproex sodium may be more effective than placebo for global symptomatology, level of functioning, aggression, and depression."

"Neuroleptics have a modest, but broad therapeutic effect on symptoms in all domains. Doses are lower than those used for treating schizophrenia. Antidepressants have a more inconsistent effect. Tricyclics have been the least successful, whereas irreversible MAO inhibitors and selective serotonin reuptake inhibitors (SSRIs) have been effective in treating mood symptoms and impulsivity. Lithium has a possible effect in diminishing anger and suicidal symptoms.
As there is no "drug of choice" for the treatment of borderline personality disorder, a more rational clinical approach might be to treat different symptom clusters (cognitive/schizotypal, affective, impulsive) rather than the disorder itself."
Zyprexa

Schulz SC, Camlin KL, Berry SA, Jesberger JA.
Department of Psychiatry, University of Minnesota Medical School, Minneapolis 55454-1495, USA.Open-label pilot study where borderlines treated with Zyprexa "showed statistically significant reduction in self-rated and clinician-rated scales. Symptoms associated with BPD and dysthymia were among those to be substantially reduced. Further studies to explore olanzapine's efficacy versus placebo, as well as comparison to other potential treatments for BPD, are important next steps."
Naltrexone in the treatment of dissociative symptoms in patients with borderline personality disorder: an open-label trial.

Bohus MJ, Landwehrmeyer GB, Stiglmayr CE, Limberger MF, Bohme R, Schmahl CG.
Department of Psychiatry, University of Freiburg, Freiburg im Breisgau, Germany.BPD and PTSD consumers many times experience dissociative symptoms, including flashbacks. Female BPD patients were treated with naltrexone, an opiate antagonist; 25 to 100 mg three times a day., for at least 2 weeks. The "scores reflected a highly significant reduction of the duration and the intensity of dissociative phenomena and tonic immobility as well as a marked reduction in analgesia during treatment with naltrexone. Six of 9 patients reported a decrease in the mean number of flashbacks per day.
CONCLUSION: These observations support the hypothesis that an increased activity of the opioid system contributes to dissociative symptoms, including flashbacks, in borderline personality disorder and suggest that these symptoms may respond to treatment with opiate antagonists."

Replication is needed with larger groups, but these results suggest that partial hospitalization may offer an alternative to inpatient treatment."

"Epilepsy and non-localized brain dysfunction have been invoked, among others, as underlying factors in borderline personality disorder. We have recorded 58 electroencephalograms in 20 borderline patients, first after complete drug washout and then under carbamazepine or placebo double-blind treatment. Taking into account only definite abnormal tracings, we found a 40% incidence of abnormal diffuse slow activity. No patient disclosed focal or epileptiform EEG features. Carbamazepine did not appear to modify the electroencephalogram."- Tegretol

Relatives of borderline outpatients were studied for mood disorders and for personality disorders. There were increased rates of mood disorders and personality disorders in the relatives of borderlines compared with never psychiatrically ill patients. "Familial aggregation of psychiatric disorders was generally similar for borderline personality and the mood disorder comparison group. The results suggest there may be common etiological factors between borderline personality disorder and mood disorders."Genetics of patients with borderline personality disorder.

"An overview of the existing literature suggests that traits similar to BPD are influenced by genes. It is too early to say to what extent BPD is also influenced by genes, but because personality traits generally show a strong genetic influence, this should also be true for BPD. Nonetheless, if the equal-environment assumption were to be violated for MZ and DZ pairs, twin studies may be overestimating genetic effects and hiding the effect of common family environment. The less than-ideal reliability of measurements used in this research may also reduce the effects of genes and common environment while increasing the effects of unique or nonshared environment. The effect of genes on the development of BPD is likely substantial. The effect of common family environment may be close to zero. More studies, large and small, are needed to reach firmer conclusions about the influence of genetics on BPD."

Are children of mothers with the BPD at higher risk for psychopathology? 21 children of BPDs were studied with 23 children of non borderline mothers. Diagnoses were obtained and global assessments were taken using tests. "Physical, sexual, and verbal abuse, as well as family violence and placements, were also assessed.RESULTS: The children of the borderline mothers, as compared with controls, had more psychiatric diagnoses, more impulse control disorders, a higher frequency of child BPD, and lower CGAS scores. There were no differences between the groups for trauma. CONCLUSION: The offspring of borderline mothers are at high risk for psychopathology."
Stay tuned....More will be coming.
