How does borderline personality disorder affect management and treatment response of patients with major depressive disorder? A comprehensive review. J Affect Disord 2021; 281:581-589. [PMID: 33250202 DOI: 10.1016/j.jad.2020.11.111] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 11/11/2020] [Accepted: 11/18/2020] [Indexed: 01/05/2023]
Abstract
BACKGROUND Borderline Personality Disorder (BPD) and Major Depressive Disorder (MDD) are two clinical conditions that often co-occur, sharing several neurobiological aspects and clinical features. Depressed patients with BPD frequently report marked dysphoria, anger, emptiness and fear of abandonment. All these elements make the clinical management of MDD in patients with BPD challenging. The purpose of the present manuscript is to summarize the current literature about the effect of BPD on treatment response and management of patients affected by MDD. METHODS A bibliographic research on the main databases (PubMed, Embase, PsycInfo, Isi Web of Knowledge, Medscape, The Cochrane Library) was performed selecting published papers from 1987 until 16th April 2020 and 13 studies were finally included in this review. RESULTS Most of the studies focused on the response to antidepressants, psychotherapeutic treatments or their combinations in patients with both MDD and BPD. In general, the co-occurrence of BPD seems to be associated with a poorer response to MDD treatment. LIMITATIONS The data are not often replicated and most of the studies focus on different treatments, so that it is difficult to compare them. CONCLUSIONS The presence of BPD seems to hamper the achievement of symptom remission in MDD patients, while the combination of selective serotonin reuptake inhibitors (SSRI) and psychotherapy may represent a valid option to treat these patients. Future studies, however, will have to confirm more robustly the findings reported in the present article and to investigate other possible treatment strategies.

Abstract
OBJECTIVE Previous research suggests that electroconvulsive therapy (ECT)-the criterion standard for the treatment of severe depression-is not as effective when the patient has comorbid borderline personality disorder (BPD). The ECT outcomes of patients with and without BPD were compared in a retrospective chart review to test this claim. METHODS We enrolled 137 patients with a diagnosis of major depressive disorder who completed the McLean Screening Instrument for Borderline Personality Disorder. Twenty-nine patients had positive screening scores for BPD. The difference in Patient Health Questionnaire (PHQ-9) scores before and after ECT was compared between patients with and without BPD. Follow-up PHQ-9 scores determined after treatment were collected and analyzed. RESULTS Electroconvulsive therapy equally improved symptoms of depression as measured by PHQ-9 score in both patients who screened positive and patients who screened negative for BPD. No difference in the increase in PHQ-9 scores between these 2 groups was noted 1 month after treatment (P = 0.19). CONCLUSIONS These data showed that a positive BPD screen does not necessarily predict a poorer response to ECT, nor does it predict greater symptom recurrence after ECT. This does not suggest that ECT is necessarily an appropriate treatment for major depressive disorder in patients with a comorbid BPD, given the limitations of screening instruments.

Abstract
Borderline Personality Disorder (BPD) has been associated with altered hypothalamic-pituitary-adrenal (HPA) axis functioning. However, evidence is inconsistent. Therefore, the present series of meta-analyses aimed to quantify HPA axis functioning in BPD patients based on singular and continuous cortisol assessments and measures of reactivity to pharmacological and psychosocial stress. Case-control studies comparing adult BPD patients and healthy and clinical controls were considered for inclusion. The search resulted in 804 publications, of which 37 studies (k = 81; BPD n = 803, controls n = 1092) were included. Analyses were based on random effect models using standardized mean differences. BPD patients displayed elevated continuous cortisol output and blunted cortisol following psychosocial challenges. Singular cortisol assessments and cortisol after pharmacological challenges were not significantly different. Meta-analyses were limited by inconsistent reporting in individual studies and small samples for some comparisons. Due to the debilitating nature of stress-related symptoms in BPD, more research on elevated continuous cortisol output and blunted cortisol responses to psychosocial stress is warranted.

Abstract
BackgroundPrevious studies of borderline personality disorder report neuropsychological impairments in several domains, including memory. No studies have compared memory functioning in high-risk prisoners with borderline personality disorder with similar prisoners with other personality disorders.AimsTo explore mnemonic impairments in prisoners undergoing personality assessment as part of the dangerous and severe personality disorder initiative or detained in a medium secure facility.MethodWe investigated memory function in 18 prisoners with borderline personality disorder and 18 prisoners with other personality disorders.ResultsPrisoners with borderline personality disorder exhibited a pattern of multi-modal impairments in the immediate and delayed recall of verbal and visual information, with some association with affective instability. These deficits were not associated with the severity of personality disturbance.ConclusionsThese data suggest that memory deficits have some specificity in relation to the constituent traits of borderline personality disorder and indicate that neuropsychological assessment may be a source of useful adjunctive information for distinguishing between the cognitive and psychological difficulties of individual prisoners.

Abstract
Aggression is a core feature of borderline personality disorder (BPD). Well-replicated results from the general population indicate that men engage in aggression more frequently than women. This article addresses the question of whether gender also influences aggression in BPD, and whether the neurobiological mechanisms underlying aggressive behavior differ between male and female BPD patients. Data show that most self-reports, interviews and behavioral tasks investigating samples of BPD patients do not find enhanced aggressiveness in male patients, suggesting that BPD attenuates rather than aggravates gender differences usually present in the general population. Neurobiological studies comparing BPD patients with gender-matched healthy controls, however, reveal a number of interesting gender differences: On the one hand, there are well-replicated findings of reduced amygdala and hippocampal gray matter volumes in female BPD patients, while these findings are not shared by male patients with BPD. On the other hand, only male BPD patients exhibit reduced gray matter volume of the anterior cingulate cortex, increased gray matter volume of the putamen, reduced striatal activity during an aggression task, and a more pronounced deficit in central serotonergic responsivity. These neurobiological findings point to a particular importance of impulsivity for the aggression of male BPD patients. Limitations include the need to control for confounding influences of comorbidities, particularly as male BPD patients have been consistently found to show higher percentages of aggression-predisposing comorbid disorders, such as antisocial personality disorder, than female BPD patients. In the future, studies which include systematic comparisons between females and males are warranted in order to disentangle gender differences in aggression of BPD patients with the aim of establishing gender-sensitive treatments where needed.

Abstract
Borderline personality disorder (BPD) and major depressive disorder (MDD) commonly co-occur, but the relationship between these disorders remains unclear. While BPD patients often suffer from depression, their subjective experience and treatment response are different from that experienced by MDD patients without BPD. Surveying the current literature on the interface of these two pathologies, we find that depression in BPD has distinct symptoms, treatment responses, remission predictors, and suicide risks. It tends to be subjectively more severe, more interpersonally fueled, and more persistent than MDD without BPD. BPD depression responds less well to biological treatments and may be fueled by the neurobiology of BPD. These findings suggest that clinicians should recognize the unique features of BPD depression and anticipate a clinical trajectory that may be different from MDD without BPD, keeping in mind that BPD depression tends not to improve until BPD improves.

Abstract
Dysfunction in the dopaminergic and serotonergic neurotransmitter systems has been demonstrated to be important in the etiology of borderline personality disorder (BPD). We investigated the relationship of two BPD risk factors, the HTR1A promoter polymorphism -1019C > G (rs6295) and the dopamine transporter (DAT1) repeat allele, with BPD in a major depressive disorder cohort of 367 patients. Out-patients with major depressive disorder were recruited for two treatment trials and assessed for personality disorders, including BPD. DNA samples were collected and the rs6295 polymorphism was detected with a TaqMan(®) assay. The DAT1 repeat allele was genotyped using a modified PCR method. The impact of polymorphisms on BPD was statistically analyzed using uncontrolled logistic and multiple logistic regression models. BPD patients had higher frequencies of the DAT1 9,9 (OR = 2.67) and 9,10 (OR = 3.67) genotypes and also those homozygous HTR1A G allele (OR = 2.03). No significant interactions between HTR1A and DAT1 genotypes, were observed; however, an increased risk of BPD was observed for those patients who were either 9,10; G,G (OR = 6.64) and 9,9; C,G (OR = 5.42). Furthermore, the odds of BPD in patients exhibiting high-risk variants of these two genes differed from those of patients in low-risk groups by up to a factor of 9. Our study provides evidence implicating the importance of the serotonergic and dopaminergic systems in BPD and that the interaction between genes from different neurotransmitters may play a role in the susceptibility to BPD.

Abstract
Several psychiatric disorders, including borderline personality disorder (BPD), are characterized by emotional dysregulation and impulse dyscontrol. More specifically, symptoms in patients with BPD often occur within the context of disruptions in attachment and related distortions in cognitive-affective processing of the self and others. From a neurocircuitry perspective, findings include prefrontal hypoactivity, amygdala hyperreactivity, and alterations in prefrontal-limbic interaction. Molecular pathways relevant to these circuits include the serotonergic, noradrenergic, and dopaminergic systems, and there is some evidence that pharmacotherapy with agents that act on these systems may be useful. Given the disruptions in attachment and schemas of the self and others in BPD, establishing a therapeutic alliance is crucial while psychotherapy remains the cornerstone of an integrated approach to management.

Abstract
Since 2005, increasing numbers of seizures of the designer drug of abuse 1-(3-chlorophenyl)piperazine (mCPP) have been reported. This paper describes the unequivocal proof of a mCPP intake. Differentiation from the intake of its precursor drugs trazodone and nefazodone was performed by a systematic toxicological analysis (STA) procedure using full-scan GC-MS after acid hydrolysis, liquid-liquid extraction and microwave-assisted acetylation. The found mCPP/hydroxy-mCPP ratio indicated altered metabolism of this cytochrome (CYP) 2D6 catalyzed reaction compared to published studies using the same procedure. Although this might be ascribed to a poor metabolizer (PM) phenotype, genotyping revealed no PM genotype but indications for an intermediate metabolizer genotype. However, a PM phenotype could also be caused by drug-drug interactions with CYP2D6 inhibitors or substrates such as the co-consumed cocaine and diltiazem and/or diltiazem metabolites, respectively. In conclusion, the presented data indicate a possible relevance of CYP2D6 polymorphism and/or drug interactions to mCPP toxicokinetics, which is important for risk assessment of this new designer drug of abuse, in particular if it is used as adulterant of CYP2D6 substrates such as cocaine.

Abstract
OBJECTIVE Acute administration of the partial serotonin (5-HT) agonist meta-chlorophenylpiperazine (m-CPP), that is used also as a street drug, has been reported to induce a "high" and craving response in various impulsive and substance addiction disorders. INTRODUCTION To clarify altered 5-HT metabolism in pathological gamblers and to explore the specific role of serotonergic system in non-substance addictions, we assessed behavioral ("high" and "craving") and neuroendocrine (prolactin and cortisol) responses to an oral single dose of m-CPP and placebo in pathological gamblers and matched controls. Moreover, the relationship between neuroendocrine outcome and clinical severity has been assessed. METHOD Twenty-six pathological gamblers and 26 healthy control subjects enter a double-blind, placebo-controlled-crossed administration of orally dose m-CPP 0.5 mg/kg. Outcome measures included prolactin and cortisol levels, gambling severity, mood, craving and "high" scales. RESULTS Pathological gamblers had significantly increased prolactin response compared to controls at 180 minutes and at 210 minutes post-administration. Greater pathological gamblers severity correlated with increased neuroendocrine responsiveness to m-CCP, suggesting greater 5-HT dysregulation. Pathological gambling patients had a significantly increased "high" sensation after m-CPP administration compared with control. CONCLUSION These results provide additional evidence for 5-HT disturbance in pathological gamblers and they support the hypotheses that the role of the 5-HT dysfunction related to the experience of "high" might represent the pathway that leads to dyscontrolled behavior in pathological gamblers. Furthermore, the "high" feeling induced by m-CPP in pathological subjects may represent a marker of vulnerability to both behavioral and substance addictions.

Abstract
Metachlorophenylpiperazine (mCPP) is a psychoactive substance that appeared in 2004 on the black market of illicit substances in Europe and France. It has a strong affinity for serotoninergic receptors and the serotonin transporter. In humans, mCPP induces endocrine, neurological and psychiatric effects. Its subjective effects are similar to those of amphetamines. However, drug-users allot few positive subjective effects. Reported cases of intoxication are generally not serious but the risks of psychiatric disorders and serotoninergic syndrome must be taken into account. Risk factors of the intoxication to mCPP are the existence of predisposing psychiatric pathologies and pharmacodynamic or metabolic interactions. mCPP does not exhibit reinforcing effects. mCPP is not the subject of any international regulation: procedures of medical and social risk assessment were implemented in European and the national levels.

Abstract
Impulsive aggression is associated with central serotonergic dysfunction. Animal models particularly implicate the 5-HT(1A) receptor in this behavior. We tested the hypothesis that central 5-HT(1A) receptor function is impaired in impulsive aggressive personality disorder patients. A total of 52 individuals with DSM-III-R personality disorders, all medically healthy adult outpatients without concurrent psychiatric medication treatment, underwent serial plasma cortisol, prolactin, and temperature measurements before and after ipsapirone 20 mg oral administration. Subjects completed self-report measures of impulsivity, hostility, depression and anxiety, and childhood maltreatment. Stepwise regression analysis revealed impulsivity alone among symptom measures to be associated with significantly decreased peak cortisol and prolactin responses. Diagnoses of borderline personality disorder (BPD) and intermittent explosive disorder-revised (IED-R) were associated with significantly increased and decreased cortisol responses, respectively. However, post hoc analyses indicated that impulsivity was significantly negatively correlated with cortisol responses in the BPD group, and may mediate the association of both BPD and IED-R with altered cortisol responses. Temperature response was associated with neither diagnostic nor symptom measures. Neither diagnostic nor dimensional measures of depression or anxiety, nor severity of childhood maltreatment, were significantly associated with cortisol, prolactin, or temperature responses. Impulsivity is related to impaired function at (or downstream to) postsynaptic 5-HT(1A) receptors, and this relationship may be partly responsible for the association of impaired serotonergic function with diagnoses such as BPD and IED-R. In addition, D(2) receptor dysfunction may play a role in impulsivity, whereas 5-HT(1A) cell-body autoreceptor function may be spared in these disorders.

Abstract
BACKGROUND Both animal and clinical studies have implicated serotonergic dysfunction in the pathogenesis of alcohol abuse and dependence. However the exact mechanisms involved remain unknown. Theoretically, low serotonin promotes alcohol seeking behavior. Sumatriptan is a serotonin1D agonist. It is postulated that sumatriptan's agonism at this terminal autoreceptor increases negative feedback, creating a net effect of decreased serotonergic neurotransmission. Administration of sumatriptan should therefore produce a craving for alcohol and the desire to drink. METHODS Fifteen patients with alcohol dependence who had undergone detoxification were recruited. Sumatriptan (100 mg) and placebo was administered in cross-over fashion on 2 separate days 72 hours apart. Both patients and raters were blind to all treatments. Patients were assessed on the following scales at -30, 0, 30, 90, 150 and 210 minutes: A 6-item scale designed to rate the patient's intention to drink; The Sensation Scale; a 13-item affect analog scale designed to rate the pattern and extent of emotional changes; and an 8-item scale designed to rate the patient's craving for alcohol. RESULTS No significant differences were found between the placebo and sumatriptan groups and no significant cross over effects were found. CONCLUSION The general lack of efficacy of sumatriptan in producing alcohol-like symptoms or a desire to drink alcohol may suggest that the 5HT1D receptor plays little role in the pathophysiology of alcoholism.

Abstract
Neuroimaging studies of impulsive-aggressive subjects with borderline personality disorder (BPD) demonstrate hypometabolism in areas of prefrontal and frontal cortex, and a blunted cortical metabolic response to challenge with serotonergic agonists. Neuroendocrine responses to serotonergic challenge are known to vary greatly by gender, and may be related to sex differences in expression of impulsive aggression. We conducted single-blind, placebo-controlled fenfluramine-activated positron emission tomography (PET) studies in impulsive male and female subjects with BPD to look for gender differences in cortical response. The sample comprised 22 BPD (15 female, 7 male) and 24 control subjects (10 female, 14 male) who received placebo on Day 1 and d,l-fenfluramine on Day 2 before PET neuroimaging. In response to placebo, female, but not male, controls had areas of increased uptake of fluorodeoxyglucose-F18 in prefrontal cortex compared with BPD subjects, with greatest uptake in the medial orbital frontal cortex, bilaterally. Male, but not female, BPD subjects, showed areas of increased glucose utilization compared with controls in large areas of parietal and occipital cortex, bilaterally. In response to fenfluramine (relative to placebo), significant decreases in glucose uptake were found in male, but not female, BPD subjects, centered in the left temporal lobe. Female, but not male, control subjects showed significantly decreased uptake in areas of right frontal and temporal cortex. Covarying for impulsive-aggression rendered nonsignificant the gender differences in responses to placebo or fenfluramine. Gender differences in serotonergic function may mediate differences in behavioral expression of impulsive aggression in subjects with BPD.

Abstract
After reviewing the literature on the pharmacotherapy of pathological gambling, the author discusses treatment strategies and areas for future research. The clearest indication for medicating the pathological gambler is for the treatment of comorbid disorders, primarily depression, bipolar disorder, and attention deficit hyperactivity disorder. However, there are difficulties in diagnosing the dually disordered gambler. Other current pharmacological approaches involve the use of medication to treat specific symptoms, traits, or symptom clusters; to make negative affects more tolerable; and to reduce cravings. Future approaches will be directed at subgroups of gamblers. This may include genetic profiling, paired with recognition of neurotransmitter deficits, and the identification of clinical syndromes and subtypes. The author also discusses the kindling hypothesis as it may pertain to pathological gambling. The presence of kindling would make a strong case for earlier and more aggressive use of medication and for long-term maintenance to prevent relapse.

Abstract
This article reviews pharmacologic trials conducted between 2000 and 2003 directed at the treatment of borderline personality disorder, antisocial personality disorder, and schizotypal personality disorder. Atypical antipsychotics, antiepileptics, selective serotonin reuptake inhibitors, omega fatty acids, and opioid antagonists have all been studied in the treatment of borderline personality disorder with positive results. Atypical antipsychotics have been studied in both schizotypal personality disorder and antisocial personality disorder, again with encouraging outcome reports. Implications of personality changes in response to pharmacologic treatment are discussed. Based on the prevalence of these disorders and the burden they cause to afflicted individuals and society, further trials are unequivocally indicated.

Abstract
The purpose of the study was to test the hypothesis that borderline personality disorder (BPD) and its underlying traits are associated with abnormalities in neurotransmitter systems. Subjects were 30 women with BPD and 22 normal controls, assessed using the Diagnostic Interview for Borderlines, revised, the Hamilton Depression Scale (HAM-A) and the Hamilton Anxiety Scale (HAM-A), the Diagnostic Assessment of Personality Pathology, the Buss-Durkee Guilt-Hostility Inventory, the Barratt Impulsivity Scale (BIS), and challenge tests to measure serotonergic, cholinergic and noradrenergic activity. Borderline subjects with high HAM-A and HAM-D scores showed a faster time to peak in prolactin response to meta-chlorphenylpiperazine (m-CPP) challenge. Borderline subjects with high BIS scores showed prolactin blunting. There were no differences in cortisol response to m-CPP, or on the cholinergic and noradrenergic challenges. The results suggest that impulsive traits in borderline patients are associated with abnormalities in serotonergic systems.

Abstract
Results from three studies suggest fluctuation in estrogen level may influence the expression of borderline personality disorder (BPD) symptoms. In the first study, 226 women were administered the Personality Assessment Inventory, borderline scales (PAI-BOR; L.C. Morey, The Personality Assessment Inventory, Professional Manual, 1991) and a questionnaire that assessed time in menstrual cycle and use of oral contraceptives, that is synthetic estrogens. BPD symptoms were most common in women using oral contraceptives and during times in the menstrual cycle when estrogen level is rising. In Study 2, 52 women were measured four times across one menstrual cycle and provided salivary samples at each test session. The samples were assayed and estrogen levels were obtained. The principle finding was that variation in estrogen levels predicted the presence of BPD symptoms (r=0.4, p<0.01). This relationship remained significant when a general increase in negative affect was statistically controlled. Study 3 employed a pre-post Oral Contraceptive (OC) design with a control group. It was found that for women with high pre-existing levels of BPD, symptoms became significantly worse after starting pill use (F (3,42)=4.7; p<0.01). Research findings that link the serotonin system and estrogen are reviewed and theoretical and practical implications are discussed.

Abstract
Behavioral impulsivity in borderline personality disorder (BPD) is associated with indices of diminished central serotonergic function, independent of suicidal behavior, depression or alcohol use disorder. Many of these studies have been conducted among males in specialized settings. Studies of BPD females, who constitute the majority of BPD patients, are generally conducted in community settings and report inconsistent findings. We studied gender differences in behavioral impulsivity and the prolactin response to D,L-fenfluramine (FEN) in BPD subjects in a community setting. A FEN challenge study was conducted with 64 BPD subjects (20 male, 44 female), and 57 controls (36 male, 21 female). Axis I and II disorders, including BPD, and suicidal histories were assessed by structured interviews. Controls were free of Axis I and II disorders. Impulsivity and aggression were assessed by the Buss-Durkee Hostility Inventory, Barratt Impulsiveness Scale, Minnesota Multiphasic Personality Inventory-Psychopathic Deviate subscale, and the Brown-Goodwin Lifetime History of Aggression. Male, but not female, BPD subjects had significantly diminished prolactin responses compared to controls. Impulsivity and aggression each predicted prolactin responses. A significant effect of BPD diagnosis on prolactin response was eliminated when impulsivity was co-varied. Impulsivity and aggression were inversely related to delta-prolactin and peak-prolactin responses among male but not female subjects. Gender differences in central serotonergic function may contribute to variations in impulsivity in BPD.

Abstract
Dysfunction of central serotonergic activity has been assumed in patients with borderline personality disorder (BPD) characterized by a prominent impulsive behavioral style. Following the high serotonergic innervation of the primary auditory cortex, there is increasing evidence of the intensity dependence of auditory evoked potentials (AEP), especially the N1/P2 component, indicating serotonergic neurotransmission in animals and humans. 15 females who met the IPDE-criteria for BPD and a group of comparative healthy females (controls) completed extensive personality questionnaires which gave special regard to impulsiveness. We obtained event-related AEP through the application of various loudness stimuli. We examined the relevant N1/P2 amplitude of the tangential dipole of the auditory evoked response using dipole source analysis. The augmentation of the N1/P2 amplitude of tangential dipole source activity with rising stimulus intensity was significantly pronounced in BPD as opposed to controls, accompanied by a reduction in N1 and P2 latencies. The strong loudness dependency of AEP correlated with aspects of impulsiveness. These data imply reduced inhibiting control over cortical sensory processing in BPD. Our findings contribute a further argument to the hypothesis of low serotonergic neurotransmission in BDP and may point to a trait character of impulsiveness in this personality disorder.

Abstract
This study has two purposes. The first purpose is to describe the severity of sexual abuse reported by a well-defined sample of borderline inpatients. The second purpose is to determine the relationship between the severity of reported childhood sexual abuse, other forms of childhood abuse, and childhood neglect and the severity of borderline symptoms and psychosocial impairment. Two semistructured interviews of demonstrated reliability were used to assess the severity of adverse childhood experiences reported by 290 borderline inpatients. It was found that more than 50% of sexually abused borderline patients reported being abused both in childhood and in adolescence, on at least a weekly basis, for a minimum of 1 year, by a parent or other person well known to the patient, and by two or more perpetrators. More than 50% also reported that their abuse involved at least one form of penetration and the use of force or violence. Using multiple regression modeling and controlling for age, gender, and race, it was found that the severity of reported childhood sexual abuse was significantly related to the severity of symptoms in all four core sectors of borderline psychopathology (affect, cognition, impulsivity, and disturbed interpersonal relationships), the overall severity of borderline personality disorder, and the overall severity of psychosocial impairment. It was also found that the severity of childhood neglect was significantly related to five of the 10 factors studied, including the overall severity of borderline personality disorder, and that the severity of other forms of childhood abuse was significantly related to two of these factors, including the severity of psychosocial impairment. Taken together, the results of this study suggest that the majority of sexually abused borderline inpatients may have been severely abused. They also suggest that the severity of childhood sexual abuse, other forms of childhood abuse, and childhood neglect may all play a role in the symptomatic severity and psychosocial impairment characteristic of borderline personality disorder.

Abstract
Serotonin is one of the neurotransmitters implicated in normal personality. Many psychobiological models of personality include some dimensions related to serotonin. For instance, the harm avoidance dimension of the biosocial model developed by Cloninger is related to serotonergic activity. Higher scores on the harm avoidance dimension should theoretically reflect increased serotonergic activity. However, correlation studies related serotonin activity to harm avoidance dimension have not yielded consistent findings. These controversial results are probably related to the complexity of the neurotransmitter systems, and the different assessment techniques used in these studies. Finally, recent genetic studies have examined the association between personality dimensions and serotonergic receptor polymorphisms with mixed results. Serotonin is not only related to some dimensions of normal personality. Several psychopathological disorders are associated with serotonergic dysfunction. More particularly, borderline personality disorder (BPD) can be defined by many of the symptoms associated with serotonergic dysregulation, including affective lability, suicidal behaviours, impulsivity and loss of impulse control. Indeed, several reports have demonstrated the efficacy of selective serotonin re-uptake drugs in treating the depressive and impulsive symptoms of patients with BPD. Moreover, some challenge studies have reported a lower serotonergic activity in BPD. Because these challenges are not specific, we have assessed the serotonergic activity in BPD with the flesinoxan challenge. Preliminary results showed that the prolactine responses to flesinoxan were significantly lower in BPD patients compared to those observed in controls.

Abstract
Disorders characterized by impulsivity include disorders of impulse control (intermittent explosive disorder, pyromania, kleptomania, pathological gambling and trichotillomania), paraphilias, sexual impulsions and sexual addictions and impulsive aggression personality disorders (borderline, antisocial, histrionic and narcissistic personality disorders). Impulsivity has a substantial impact on both individuals and society. Impulse control disorders may be conceptualized as a subset of the obsessive-compulsive spectrum. In this article, we examine the genetic and neurobiological aetiology of these disorders and possible treatment options. The link between serotonergic dysfunction and the pathophysiology of impulsivity is discussed, and studies that examine the efficacy of various selective serotonin reuptake inhibitors and other alternatives in the treatment of impulsive disorders such as pathological gambling, sexual addictions and borderline personality disorder are presented.

Abstract
Several approaches to the spectrum of obsessive-compulsive spectrum disorders have been put forward, each based on a rather different framework. To some extent, overlaps exist among these approaches, indicating that the neurobiology of OCD and related disorders is increasingly consolidated; however, important differences exist between these approaches, and many questions are unanswered, demonstrating that more work is necessary to fully delineate OCD and its subtypes and their relationships to other putative obsessive compulsive spectrum disorders. Despite the need for substantial additional research on the neurobiology of the obsessive-compulsive spectrum, this construct already has heuristic value in the clinical and research setting. It reminds clinicians to ask OCD patients about comorbid spectrum disorders, and it suggests the possible value of anti-OCD agents and behavioral techniques in patients for whom treatments were previously unavailable. It reminds investigators to consider possibly overlapping and differentiating mechanisms in several disorders. Ultimately, the delineation of such mechanisms will allow for a more rigorous approach to the putative obsessive-compulsive spectrum disorders.

Abstract
BACKGROUND Disturbances of affect, impulse regulation, and autoaggressive behavior, which are all said to be related to an altered function of the central serotonergic (5-HT) system, are prominent features of borderline personality disorder (BPD). A high coincidence of childhood physical and sexual abuse is reported in these patients. Animal studies indicate that early, sustained stress correlates with a dysfunctional central 5-HT system. Therefore, we hypothesize that sustained traumatic stress in childhood affects the responsivity of the postsynaptic serotonergic system of traumatized BPD patients. METHODS Following Axis I, Axis II, and trauma assessment, a neuroendocrine challenge test was performed with the postsynaptic serotonergic agonist meta-chlorophenylpiperazine (m-CPP) in 12 impulsive and autoaggressive female patients with BPD and 9 matched healthy volunteers. RESULTS The cortisol and prolactin responses to the m-CPP challenge in BPD patients were significantly lower compared to those in controls. Within the group of patients with BPD, the net prolactin response showed a high inverse correlation with the frequency of the physical (r = -.77) and sexual abuse (r = -.60). CONCLUSIONS Our data suggest that severe and sustained traumatic stress in childhood affects the 5-HT system and especially 5-HT(1A) receptors. This finding confirms the data from animal research. The blunted prolactin response to m-CPP appears to be the result of severe traumatization and independent of the BPD diagnosis.

Abstract
Many studies support a significant relation between low cholesterol levels and poor impulse, aggression and mood control. Evidence exists also for a causal link between low brain serotonin (5-HT) activity and these behaviors. Mechanisms linking cholesterol and hostile or self-destructive behavior are unknown, but it has been suggested that low cholesterol influences 5-HT function. This study was designed to explore the relationship between plasma cholesterol, measures of impulsivity and aggression, and indices of 5-HT function in personality disordered cocaine addicts. Thirty-eight hospitalized male patients (age 36.8+/-7.1) were assessed with the DSM-III-R, the Buss-Durkee Hostility Inventory (BDHI), the Barratt Impulsiveness Scale (BIS) and the Brown-Goodwin Assessment for Life History of Aggression. Fasting basal cholesterol (total, LDL and HDL) was determined 2 weeks after cocaine discontinuation. On the same day 5-HT function was assessed by neuroendocrine (cortisol and prolactin) and psychological (NIMH and 'high' self-rating scales) responses following meta-chlorophenylpiperazine (m-CPP) challenges. Reduced neuroendocrine responses, 'high' feelings and increased 'activation-euphoria' following m-CPP have been interpreted as indicating 5-HT alterations in a variety of psychiatric conditions. Significantly lower levels of HDL cholesterol were found in patients who had a history of aggression (P=0.005). Lower levels of HDL cholesterol were also found to be significantly associated with more intense 'high' and 'activation-euphoria' responses as well as with blunted cortisol responses to m-CPP (P=0.033, P=0.025 and P=0.018, respectively). This study gives further support to existing evidence indicating that in some individuals, the probability of exhibiting impulsive and violent behaviors may be increased when cholesterol is low. It also suggests that low cholesterol and alterations in 5-HT activity may be causally related.

Abstract
In time, mental health professionals will understand the etiology of BPD more fully. Although enormous strides have been made in the past decade, research into the multifactorial basis of BPD is still in its infancy. In particular, studies of children at high risk for developing BPD are needed. For now, the author suggests that one can admire patients with BPD for the integrity with which they have dealt with their pain. After all, not many people remain so loyal to and so respectful of such disheartening childhood experiences.

Abstract
Impulsivity can often be an important clinical problem in psychiatry and neurology. In psychiatry, the manifestation of impulsive behaviour in syndromes such as personality disorders, attention deficit hyperactivity disorder and in substance abuse may be different, and this has led to conflicting definitions. There has also been a tendency to concentrate on the nature of the behavioural manifestation (problems with the law, aggression, drug use, behavioural problems in school) rather than shared psychological processes, and to ignore the fact that impulsivity can also have positive aspects. In a normal population, the personality trait of impulsivity has been analysed using personality inventory questionnaires. Analysis of these data lead to the suggestion that impulsivity as commonly defined and understood may be made up of several independent factors, which may have separate biological bases. These self-rating questionnaires have been complemented by objective tests that are now often computerized, and which have been used in man (e.g. with criminal offenders, children, or patients who have undergone brain surgery). Some of these tests, such as the differential reinforcement of low rates procedure or the delay of reinforcement procedure, have also been used to study impulsivity in animals. Analysis of the behavioural principles of these tests suggests that they too may reflect different aspects of impulsivity. Many different biological systems have been proposed to contribute to the neurobiological basis of impulsivity. The serotonergic neurotransmitter system has recently received the most attention, with evidence of its involvement coming from animal studies as well as from studies in psychiatric patients. The frontal lobes have been proposed to play an important role in regulating impulsivity, although it unclear how specific this is. None of this biological knowledge has yet led to reliable pharmacotherapy for excessive impulsivity and, as yet, there is little understanding of the mechanisms by which those drugs, which have been found empirically to have some efficacy (e.g. the psychomotor stimulants in attention deficit hyperactivity disorder), exert their therapeutic effect. By bringing together knowledge from different areas of research it is hoped that a cross fertilization will be achieved, which will lead to a sharpening of concepts, an improvement in methodology and the stimulation of biological studies.

Abstract
There is evidence from clinical, epidemiological, and neuroimaging studies that attention-deficit hyperactivity disorder (ADHD) and seasonal affective disorder (SAD) may have several features in common. To assess seasonal affective symptoms in adults with ADHD, 115 individuals attending an adult ADHD clinic in Toronto, Ontario, Canada were asked to complete the Seasonal Pattern Assessment Questionnaire (SPAQ). From this clinic population of 115, a total of 56 completed SPAQs were returned. Assuming that all individuals failing to complete the SPAQ were nonseasonal and depending on which case-finding criteria were used, the rate of SAD in the overall clinic sample was estimated at either 10.4% (Terman criteria) or 19.1% (criteria of Kasper et al.). These prevalence rates are significantly greater than the rates reported in large population surveys at similar latitudes. There was an apparent relationship between female gender, impulsive-subtype ADHD, and seasonality. Future studies to examine whether core symptoms of ADHD fluctuate across the seasons and to assess the efficacy of light therapy in "seasonal" ADHD patients would be of great theoretical and clinical interest.

Abstract
BACKGROUND The aim of the present study was to examine the relationship between suicidal behavior and impulsiveness, and more generally borderline personality disorder on the one hand, and platelet indicators of central serotonergic function on the other. METHODS After a suicide attempt platelet serotonergic measures were obtained from 144 patients with at least one previous attempt. A major DSM-III-R Axis I diagnosis and the use of antidepressants were reasons for exclusion. RESULTS Platelet monoamine oxidase (MAO) activity was negatively correlated with the personality traits "multi-impulsive behavior" and "disinhibition." In accordance, platelet MAO activity was also lower in patients with less-planned suicide attempts. Platelet serotonin (5-HT) and recidivism were positively correlated with borderline personality disorder, in particular chronic feelings of emptiness. Platelet 5-HT was lower in patients with alcohol abuse. The maximum number of binding sites (Bmax) for paroxetine binding was positively correlated with "sensation seeking." CONCLUSIONS These findings support the hypothesis that serotonergic involvement in impulsive suicidal behavior is mediated by the relationship between serotonergic function and impulsiveness as personality trait. Other borderline personality traits relevant to recurrent suicidal behavior, in particular chronic feelings of emptiness, appear also related to serotonergic measures.

Abstract
In North America, there may be no other psychiatric diagnosis more laden with stereotypes and stigma than borderline personality disorder. People who live with this label--the majority being female--are often marginalized or denied access to mental health services. In this article, the author reviews the theoretical underpinnings of the diagnosis, as well as the stigmatizing practices and limited services for seriously ill persons with borderline personality disorder diagnoses. In light of this review, new directions for mental health practice, education, and research are proposed.

Abstract
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.

Abstract
We searched for regional cerebral metabolic disturbances in patients with borderline personality disorder (BPD). Ten inpatients with BPD, no current DSM-IIIR Axis I diagnosis and free of any psychotropic substances, were compared with 15 age-matched control subjects using positron emission tomography with 2-deoxy-2-[18F]fluoro-D-glucose and semiquantitative analysis of regional glucose metabolic activity. We found relative hypometabolism in patients with borderline personality disorder at the level of the premotor and prefrontal cortical areas, the anterior part of the cingulate cortex and the thalamic, caudate and lenticular nuclei. This study shows significant cerebral metabolic disturbances in patients with borderline personality disorder. These metabolic disturbances, which are similar to some of those described in other psychiatric entities, may help to understand the characteristic clinical aspects of this disorder.

Abstract
We report on the neuroendocrine and psychological responsivity of 31 cocaine addicts and 14 controls to the serotonergic agonist, meta-chlorophenylpiperazine (m-CPP) (0.5 mg/kg p.o.). Cocaine addicts were subdivided into subjects with aggressive tendencies and other features similar to those found in type 2 alcoholics and subjects without these features. Following m-CPP, aggressive and nonaggressive patients had a significantly blunted prolactin response compared to controls, but there was no difference between the two patient subgroups. There was no difference between the cortisol responses of nonaggressive patients and controls, but aggressive patients had a significantly blunted cortisol response compared to controls and nonaggressive patients. Both patient subgroups reported more intense "activation-euphoria" and "high" responses following m-CPP than controls. These results could indicate the existence of alterations along serotonergic pathways in cocaine addicts taken as a group. In addition, a subgroup of patients who could be described as type 2 cocaine addicts appear to be biologically different from healthy subjects and from other cocaine addicts as indicated by a greater cortisol blunting following m-CPP.

Abstract
As noted previously, it is likely that the tendency to lash out verbally or physically at others is influenced by an interaction among multiple complex biologic factors. We need to investigate how these systems interact with each other to develop a more thorough understanding of the brain's influence over aggressive behavior. We are at a very early stage in our understanding of the neurobiology of aggression. There are no simple tools for studying the complex neurophysiology of the human brain. The studies cited in this article include techniques limited in their utility. As our technologies improve, discovering a more thorough picture of the brain's influence over aggressive behavior may be possible. For example, functional neuroimaging may help to localize abnormal neurotransmitter functioning in the brains of individuals with impulsive aggressive behavior. Our technologies are beginning to reveal the differential effects of subsystems of neurotransmitter regulation. Subtypes of serotonin receptors may differentially mediate impulsive aggressive behaviors. Animal studies suggest that 5-HT 1A receptor stimulation results in a decrease in aggressive behavior. As noted previously, aggressive personality-disordered patients show a blunted prolactin response to the 5-HT1A agonist buspirone. Antagonism of 5-HT 2 receptors appears to decrease aggression, and this effect may explain the ability of newer antipsychotic agents (which, unlike older antipsychotic medications, block 5-HT 2 receptors) to produce a dramatic reduction in aggression and agitation independent of effects on psychotic symptoms. Neglecting psychosocial factors in the causes of aggressive behavior would also be naive. Although environmental factors account for much of the predisposition to aggression, there have been few systematic studies to explore the relationship between life experiences and aggression. In addition, there have been no well-designed studies of the interaction between biology and an individual's environment in the genesis of aggressive behavior. There is some evidence of an association between childhood abuse and neglect and adult antisocial personality disorder, but this relationship might be merely an artifact of the genetic relationship between parental and offspring antisocial personality disorder. As we discussed in the introduction, one of the biggest hurdles in the study of the neurobiology of aggression is the lack of a consensus on definitions. "Intermittent Explosive Disorder" is the only category in DSM-IV that directly addresses individuals with problems with aggression, but the criteria are vague and only focus on a handful of the many patients who exhibit problems with aggressive behavior. It is our hope that investigators in this field can work together toward developing more precise and encompassing diagnostic criteria to study effectively both the neurobiology and treatment of these disorders.

Abstract
The serotonergic system has been linked to the etiology of several, albeit disparate, psychiatric disorders. The accumulation of many lines of evidence support the view that there are gender differences in the serotonergic system in humans. It is further proposed that a gender differentiated serotonergic system acts as the nidus for the development of gender-specific psychiatric disorders. Depression, anxiety and eating disorders are largely seen in females, whereas alcoholism, aggressivity and suicide predominate in males. Evidence from both animal and human studies suggesting that the serotonergic system mediates between social-environmental experience and biological states is presented and reviewed. A reconceptualization of the serotonergic system as a gender-specific psychobiological interface is proposed. (Int J Psych Clin Prac 1997; 1: 3-13).

Abstract
I examined the relationships among childhood abuse, alexithymia, and personality disorder. Participants were 60 adults who were receiving outpatient psychotherapy. Both the participants and their therapists used the Toronto Alexithymia Scale to provide independently information concerning the client's level of alexithymia. The therapists provided information concerning DSM-III-R personality disorder diagnoses, and participants completed portions of the Personality Diagnostic Questionnaire-Revised. Information concerning childhood abuse history was obtained from the therapists. As expected, childhood abuse, alexithymia, and personality disorder were all associated with each other. The abilities to identify and communicate emotions were differentially associated with childhood abuse and personality disorder.

Abstract
We have previously found that a subgroup of patients with impulsive personality disorders respond to m-chlorophenylpiperazine (m-CPP) administration with a distinctive spacy/high behavioral reaction and with increased cortisol responses. In this report we analyzed the relationship between behavioral and neuroendocrine responses to m-CPP in an enlarged sample of patients with borderline personality disorder (BPD). We also assessed the association of behavioral and neuroendocrine responses with clinical symptoms and with m-CPP blood levels. We found that in BPD patients the presence of a spacy/high behavioral response was significantly associated with increased prolactin and cortisol responses to m-CPP. In BPD patients increased m-CPP levels were significantly associated with neuroendocrine hypersensitivity and with a spacy/high behavioral response, while in controls increased m-CPP levels were not significantly associated with neuroendocrine hypersensitivity but were significantly associated with dysphoric behavioral responses. Taken together with previous work on m-CPP in obsessive-compulsive disorder, these results are partially consistent with the hypothesis that compulsive and impulsive symptoms fall at opposite ends of a phenomenologic and neurobiologic spectrum.

Abstract
Since the introduction of international psychiatric classification systems, systematic diagnostic methods have become available for personality disorders. Recent developments in the dimensional diagnostic approach of personality disorders have yielded relationships between this type of disorders and neurobiological processes including both monoaminergic and stress-hormonal systems. It is hypothesized that the pathogenesis of borderline personality disorders is related to an enhanced serotonergic tone in septo-hippocampal structures. Preliminary clinical data are suggestive for potential therapeutic effects of serotonin-modulating compounds in borderline personality disorders.

Abstract
Nosological orientation in psychiatry has severely hampered the progress of research in biological psychiatry, especially in the case of personality disorders. Dimensional approaches have redefined the characteristics of these disorders and their possible pathogenetic factors. The significance of arousal and stress, so far relatively neglected in clinical research, and its important function in adaptive and coping strategies has to be included in the study of the behavioral pharmacology of personality disorders. Some preliminary clinical data are available suggesting the potential therapeutic use of serotonin modulating agents in the key symptomatology of certain personality disorders such as disturbed impulsive regulation and increased stress reactivity.
