Article: Synaptosomal-associated protein 25 gene polymorphisms and antisocial personality disorder: association with temperament and psychopathy.
[show abstract] [hide abstract]
ABSTRACT: The molecular genetic of personality disorders has been investigated in several studies; however, the association of antisocial behaviours with synaptosomal-associated protein 25 (SNAP25) gene polymorphisms has not. This association is of interest as SNAP25 gene polymorphism has been associated with attention-deficit hyperactivity disorder and personality. We compared the distribution of DdeI and MnII polymorphisms in 91 young male offenders and in 38 sex-matched healthy control subjects. We also investigated the association of SNAP25 gene polymorphisms with severity of psychopathy and with temperament traits: novelty seeking, harm avoidance, and reward dependence. The MnII T/T and DdeI T/T genotypes were more frequently present in male subjects with antisocial personality disorder (APD) than in sex-matched healthy control subjects. The association was stronger when the frequency of both DdeI and MnII T/T were taken into account. In the APD group, the genotype was not significantly associated with the Psychopathy Checklist-Revised scores, measuring the severity of psychopathy. However, the APD subjects with the MnII T/T genotype had higher novelty seeking scores; whereas, subjects with the DdeI T/T genotype had lower reward dependence scores. Again, the association between genotype and novelty seeking was stronger when both DdeI and MnII genotypes were taken into account. DdeI and MnII T/T genotypes may be a risk factor for antisocial behaviours. The association of the SNAP25 DdeI T/T and MnII T/T genotypes with lower reward dependence and higher novelty seeking suggested that SNAP25 genotype might influence other personality disorders, as well.Canadian journal of psychiatry.

Article: Temperament traits and psychopathy in a group of patients with antisocial personality disorder.
[show abstract] [hide abstract]
ABSTRACT: The Psychopathy Checklist Revised (PCL-R) and Temperament and Character Inventory (TCI) have been used extensively in research of personality disorders; however, no previous study has investigated the relation between psychopathy factors and temperament and character traits in patients with antisocial personality disorder (ASPD). Our aim was to fill this gap in the literature. The PCL-R Factor scores and the TCI temperament and character scores were evaluated in 68 men with ASPD and 65 healthy male controls. The ASPD cases had significantly higher PCL-R Factor 1, Factor 2, and Total scores, as well as significantly higher TCI Novelty Seeking and Harm Avoidance scores, whereas the control group had higher TCI Reward Dependence, Persistence, Self-Directedness, and Cooperativeness scores. Correlation analysis revealed that, in the whole study group, PCL-R Factor 1, Factor 2, and Total scores were positively correlated with Novelty Seeking and Harm Avoidance scores and negatively correlated with Reward Dependence, Persistence, Self-Directedness, and Cooperativeness scores. When each group was analyzed separately, the correlations were not significant. Regression analysis supported the main findings. Our results showed that both PCL-R Factor 1 score, which is claimed to reflect "core psychopathy," and PCL-R Factor 2 score, which reflects criminal behaviors, were positively correlated with Novelty Seeking and Harm Avoidance and were negatively correlated with Reward Dependence in the whole sample. The reduced variance of PCL-R in each group might lead to nonsignificant associations within groups. Without the subjects with severe psychopathy in the present study, it might not be possible to show the association.Comprehensive psychiatry 03/2011; 52(6):607-12. · 2.08 Impact Factor -

Article: Plasma orexin A, ghrelin, cholecystokinin, visfatin, leptin and agouti-related protein levels during 6-week olanzapine treatment in first-episode male patients with psychosis.
[show abstract] [hide abstract]
ABSTRACT: The objective of the study was to investigate the change of body mass index (BMI), waist circumference, lipid profile, leptin, ghrelin, orexin, visfatin, agouti-related protein, and cholecystokinin levels during 6 weeks of olanzapine treatment in newly diagnosed first-episode drug naive, young adult, nonobese male patients with psychosis. Twenty male participants who were all first-episode drug naive psychotic patients without prominent affective signs and symptoms and 22 healthy male controls of similar age were included. BMI, waist circumference, fasting glucose, and lipid profiles were measured, and Positive and Negative Syndrome Scale and Brief Psychiatric Rating Scale scores were obtained at baseline, during the second and sixth week of treatment, and the aforementioned neuropeptide levels were measured at baseline and during the sixth week of treatment. Treatment was associated with significant increases in BMI, waist circumference, serum triglyceride, and low-density lipoprotein levels. BMI levels increased more than 7% in over 75% of the patients. Leptin increased, and ghrelin and orexin decreased significantly with olanzapine treatment, whereas cholecystokinin, visfatin, and agouti-related protein levels did not change significantly. In conclusion, consistent with previous studies, we found increased BMI, leptin and lipids during olanzapine treatment. Association of neuropeptide level changes with symptom improvement might be mediated by the dopaminergic and serotonergic systems.International clinical psychopharmacology 05/2010; 25(3):165-71. · 3.35 Impact Factor -
Article: Clinical characteristics of self-mutilating behavior in Turkish male subjects with antisocial personality disorder: relationship to psychopathy.
[show abstract] [hide abstract]
ABSTRACT: The aims of this study were to determine the characteristics of self-mutilation (SM) and examine the relationship between SM and psychopathy in male subjects with antisocial personality disorder (APD). APD diagnosis was established by the Structured Clinical Interview for DSM-III-R Axis II Disorders. Subjects (N = 116) were assessed using the Psychopathy Checklist-Revised and a semi-structured self-mutilation questionnaire form. In males with APD, the percentages of psychopathy and SM were 48.3% (N =56) and 96.6% (N = 112), respectively. There were positive correlations between severity of psychopathy and severity, number, and frequency of SM. Considerably high rates of SM and psychopathy were found in Turkish males with APD. The features of SM were associated with comorbidity of psychopathy. These results showed the importance of exploring the self-injurious behavior and psychopathy when diagnosed with APD.International Journal of Social Psychiatry 11/2009; 57(3):237-47. · 1.15 Impact Factor -
Article: Accompaniment of Tourette syndrome and neuropsychiatric symptoms.
[show abstract] [hide abstract]
ABSTRACT: Tourette syndrome (TS) is a neuropsychiatric disorder characterized by multiple motor tics and one or more vocal tics. Attention deficit, obsessive-compulsive disorder, personality problems, and impulsivity may be associated with TS. Functional neuro-imaging studies indicate that the ventral striatum is the most affected brain area in TS. We report a case with TS who had cerebellar atrophy, cerebellar arachnoid cyst, bilateral congenital triangular alopecia, bilateral strabismus, and oxycephaly. The association among these symptoms and TS is rare, and the possible relationship of these symptoms should be investigated with further studies.Neurosciences 07/2009; 14(3):287-9. · 0.12 Impact Factor -
Article: Evaluation of general psychopathology, subjective sleep quality, and health-related quality of life in patients with obesity.
[show abstract] [hide abstract]
ABSTRACT: Recently, the increasing rate of obesity has been elucidated as a major public health problem. The aim of this study was to examine the psychological distress, subjective sleep quality, and health-related quality of life (HRQOL) in a group of patients diagnosed with obesity. A total of 124 obese patients (32 of them Class I obesity (BMI: 30-34.9 kg/m2), 92 Class II obesity (BMI: > or = 35kg/m2)) and 106 healthy control subjects were involved in the study. Subjects were evaluated with self-administered questionnaires including the Symptoms Checklist-90-Revised (SCL-90-R), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Short Form 36 (SF-36). Several clinical and socio-demographic data were also recorded. Class II obesity group had a significantly worse psychological status, quality of life, and sleep quality than control group, Although Class I obesity group did not differ from Class II and control groups according to sleep quality and psychological status, they had worse HRQOL than the control group. BMI scores positively correlated with the majority of subscales of psychological distress (SCL-90-R) and sleep quality (PSQI, ESS) and negatively correlated with all dimensions of HRQOL (SF-36). Obesity is associated with psychological distress, poor sleep quality, and reduced quality of life. Thus, obesity should be evaluated in a biopsychosocial manner, including management of patients' psychopathology.The International Journal of Psychiatry in Medicine 01/2009; 39(3):297-312. · 1.03 Impact Factor -
Article: Reduced urinary excretion of homocysteine could be the reason of elevated plasma homocysteine in patients with psychiatric illnesses.
[show abstract] [hide abstract]
ABSTRACT: Although increased plasma total homocysteine (tHcy) concentrations were reported in psychiatric diseases, currently the reasons of elevated tHcy levels were not clearly understood. In this study we aimed to investigate the contribution of renal clearance of homocysteine on plasma tHcy load in patients with depression and first episode psychosis. Thirty depression, 14 first episode psychosis patients and 34 healthy individuals (control group) were involved in the study. In patients and control groups, plasma and urine tHcy levels, urine methylmalonic acid (uMMA), serum vitamin B12 and folate concentrations were measured. Although there was not any difference between depression, psychosis and control groups with respect to mean (SD) values of vitamin B12 (289(131), 230 (72) and 249(79) pg/mL, respectively) and folate (6.4(4.0), 5.3(2.3) and 5.7(2.3) ng/mL, respectively), plasma tHcy levels of depression and psychosis group were higher than the control values (16.3(6.2), 15.5(4.3) and 9.9(2.1) micromol/L, respectively). Urine tHcy values of patient groups were significantly lower than those in the control group (14.5(7.6), 15.8(6.8) and 29.6(16.9) micromol/g creatinine, respectively). There were elevated uMMA levels in depression and psychosis groups compared with control group (4.9(2.4), 6.6(3.2) and 2.8(1.2) mmol/mol creatinine, respectively). There were a significant and negative correlation between urinary tHcy and plasma tHcy levels (r=-0.258 and p=0.011). In conclusion, reduced urinary tHcy levels in psychiatric patients could be one of the reasons of plasma tHcy elevations with normal folate and vitamin B12 levels. Altered renal handling mechanisms of homocysteine may lead to elevated plasma tHcy levels by reduced clearance of homocysteine via glomerular filtration.Clinical biochemistry 08/2008; 41(10-11):831-5. · 2.02 Impact Factor -
Article: Effects of diagnostic comorbidity and dimensional symptoms of attention-deficit-hyperactivity disorder in men with antisocial personality disorder.
[show abstract] [hide abstract]
ABSTRACT: Although children with attention deficit hyperactivity disorder (ADHD) are at increased risk for later onset of antisocial personality disorder (APD) as adults, the utility of ADHD as either a comorbid diagnosis (ADHD(c)) or dimensional symptoms (ADHD(d)) in predicting behaviour and substance use problems in APD subjects has not been examined. A total of 105 adult male offenders with Structured Clinical Interview for Axis II Disorders (SCID-II)-based DSM-III-R APD were studied in terms of: (i) psychopathy scores on the Hare Psychopathy Checklist-Revised (PCL-R); (ii) ADHD(c) diagnostic comorbidity on clinically administered DSM-IV questionnaire; and (iii) ADHD(d) dimensional symptoms by means of Wender Utah Rating Scale (WURS) and Conners Adult ADHD Rating Scale (CAARS) during a 12 month study period (May 2005-May 2006). Sixty five per cent of APD subjects met criteria for ADHD(c) diagnostic comorbidity with significantly increased rates of childhood neglect, parental divorce and suicide attempt, but not of psychopathy. APD subjects with ADHD(d) symptoms were noted to have earlier onset and increased rate of self-injurious behaviour (SIB), suicide attempt, and psychopathy. The psychopathy scores, in turn, were predictive of earlier onset of SIB and behavioural problems. Both ADHD(c) diagnostic comorbidity and ADHD(d) symptoms need to be assessed in APD subjects and the dimensional measures may be better in detecting earlier onset SIB, suicide attempt and other behavioural problems.Australian and New Zealand Journal of Psychiatry 06/2008; 42(5):405-13. · 2.93 Impact Factor -
Article: Lack of association between DRD3 gene polymorphism and response to clozapine in Turkish schizoprenia patients.
[show abstract] [hide abstract]
ABSTRACT: It is hypothesized that molecular components of dopaminergic system, especially the dopamine D3 receptor gene (DRD3), may play a crucial role in the pathophysiology of schizophrenia, because it is abundant in the limbic system of the brain and it binds antipsychotic drugs. Several groups attempted to find an association between a serine-to-glycine polymorphism of the DRD3 gene (Ser9Gly) and schizophrenia; however, the results were inconsistent. In this study, we aimed to investigate the relationship of the Serine/Glycine polymorphism of the DRD3 gene with therapeutic response to clozapine treatment between Turkish schizophrenia patients (N = 92) and healthy controls (N = 100). Genotype groups were comparable in BPRS, SAPS, SANS analysis of response to clozapine. Our results suggest that an association between the Ser/Gly polymorphism of DRD3 gene and response to clozapine in Turkish schizophrenia patients is unlikely to exist.American Journal of Medical Genetics Part B Neuropsychiatric Genetics 05/2008; 150B(1):56-60. · 3.70 Impact Factor -
Article: A magnetic resonance spectroscopy study of antisocial behaviour disorder, psychopathy and violent crime among military conscripts
[show abstract] [hide abstract]
ABSTRACT: Background: Prefrontal and/or temporo-limbic abnormalities associated with antisocial personality disorder (APD), high psychopathy scores and violent behaviours can readily be evaluated by neuroimaging methods.Objectives: In this study, we compared the brain metabolites in adult male military conscripts with APD, high psychopathy scores and serious violent crimes (n = 15) with age- and educational-level-matched healthy controls (n = 15) by means of magnetic resonance spectroscopy.Methods: All cases were diagnosed by means of the Diagnostic Statistical Manual-IV APD module of the Structured Clinical Interview for DSM III-R Axis II Disorders (SCID-II) semistructured questionnaire in Turkish. The psychopathy scores were evaluated by means of the Hare Psychopathy Checklist-Revised translated into Turkish (PCL-R). PCL-R is a 20-item, reliable and valid instrument for assessment of psychopathy, both in categorical and dimensional natures. All patients had a total score of 29 (of possible 40) or higher from PCL-R, indicating a high degree of psychopathy.Results: Our results showed no significant differences in ratio of N-acetyl aspartate (NAA), creatine (Cr) and choline-related compounds in the right dorsolateral prefrontal cortex, anterior cingulate cortex (ACC) and amygdala–hippocampus regions of cases compared with controls. ACC NAA/Cr was significantly negatively correlated with both the PCL-R total score and the PCL-R factor I score (interpersonal/affective problems) among the cases.Conclusion: As ACC plays an important role in decision-making and emotional information processing, we postulate that the lower NAA/Cr ratio, suggesting impaired neural integrity, may increase the severity of interpersonal/affective problems of the psychopathy factor in male subjects exhibiting APD, high psychopathy overall scores and violent crimes.Acta Neuropsychiatrica 03/2008; 20(2):72 - 77. · 0.58 Impact Factor -
Article: Nightmare disorder, dream anxiety, and subjective sleep quality in patients with borderline personality disorder.
[show abstract] [hide abstract]
ABSTRACT: The aims of the present study were to examine the rate of nightmare disorder (ND) and to determine the levels of dream anxiety and subjective sleep quality in patients with borderline personality disorder (BPD). Another aim was to determine whether dream anxiety was associated with childhood trauma, dissociative experiences, and subjective sleep disturbance in BPD patients. Finally, the hypothesis as to whether BPD patients with ND exhibited a more severe clinical profile than those without ND, was also tested. A total of 88 borderline patients and 100 age- and sex-matched healthy control subjects were assessed using the Structured Clinical Interview for DSM-III-R Personality Disorders, Structured Clinical Interview for DSM-IV Axis I Disorders, Van Dream Anxiety Scale, Pittsburgh Sleep Quality Index, Dissociative Experiences Scale, and Traumatic Experiences Checklist. Subjects with codiagnoses that could affect sleep were not included. BPD patients suffered a significantly greater rate of nightmares, elevated levels of dream anxiety, and disturbed sleep quality than did controls. In the borderline group, heightened dream anxiety was correlated with higher rates of early traumatic experiences and dissociative symptoms, and impaired sleep quality. Furthermore, borderline patients with ND exhibited greater psychopathology as compared to those without ND in terms of several clinical characteristics. The present study provides support for a strong association between BPD, distressing nightmares, and subjective sleep quality. Recognition and management of dream and sleep disturbances in BPD patients might lead to improvements in their global clinical picture.Psychiatry and Clinical Neurosciences 03/2008; 62(1):48-55. · 2.13 Impact Factor -
Article: Self-mutilating behavior in patients with dissociative disorders: the role of innate hypnotic capacity.
[show abstract] [hide abstract]
ABSTRACT: Despite the fact that the assumption of a relationship between self-mutilation and dissociative disorders (DD) has a long history, there is little empirical evidence to support this premise. The present study examined this relationship and investigated whether this commonality is associated with innate hypnotic capacity. Fifty patients diagnosed with DD and 50 control subjects with major depression were assessed by using a self-mutilation questionnaire, Dissociative Experiences Scale, Traumatic Experiences Checklist, and the Eye-Roll Sign for their self-mutilating behaviors, dissociative symptoms, early trauma, and innate hypnotic capacity, respectively. We have found that 82% of the present sample of patients with DD injured themselves. They had higher scores on trauma, dissociation and eye-roll measurements than controls. In addition, DD patients with self-mutilation were more likely to have high scores of trauma, dissociation and eye-roll than those without self-mutilation. Innate hypnotic capacity was a strong predictor of self-mutilating behavior in DD patients. This study strongly supports the assumption that patients with DD are at high risk for self-mutilating behavior and points to the necessity of routine screening for self-mutilating behavior as well as the hypnotic capacity which may constitute a high risk for self-injury in this patient group.The Israel journal of psychiatry and related sciences 02/2008; 45(1):39-48. · 0.68 Impact Factor -
Article: Childhood trauma history and dissociative experiences among Turkish men diagnosed with antisocial personality disorder.
[show abstract] [hide abstract]
ABSTRACT: This study investigated the association between antisocial personality disorder (APD), childhood trauma history, and dissociative symptoms in a sample of Turkish recruits. A total of 579 male patients diagnosed with APD were examined in a military hospital setting. An age and gender matched control group of 599 normal persons with no known medical or psychiatric disorder were also chosen among military personnel. The subjects were evaluated with an assessment battery using a semi-structured interview for socio-demographic characteristics, APD section of SCID-II, an adapted version of the Structured Trauma Interview, and Dissociative Experiences Scale. Childhood sexual abuse, physical abuse, neglect, and early separation from parents were significantly more common among antisocial subjects than among controls. APD group reported significantly more dissociative symptoms and 50.4% of them reported pathological level of dissociation. Overwhelming childhood experiences of all four types were significant predictor of the APD diagnosis. Analyses also showed that childhood traumatic events and comorbid psychopathological features relevant to antisocial personality were significantly associated with pathological level of dissociation. These results revealed the importance of inquiring about patient's history of childhood traumatization and dissociative experiences when diagnosed with APD.Social Psychiatry and Psychiatric Epidemiology 12/2007; 42(11):865-73. · 2.70 Impact Factor -
Article: Clinical predictors of therapeutic response to clozapine in a sample of Turkish patients with treatment-resistant schizophrenia.
[show abstract] [hide abstract]
ABSTRACT: Several lines of evidence suggest that clozapine is more effective than both first- and second-generation antipsychotic drugs in treatment-resistant schizophrenia (TRS). However, clinicians appear to be hesitant to prescribe this drug. It would therefore be extremely valuable if predictors of response to clozapine could be identified. The aim of this study was to evaluate the predictive factors of clinical responses to clozapine in a group of Turkish patients with TRS. This was a 16-week uncontrolled open study carried out among 97 TRS patients (80 males and 17 females; DSM-IV diagnosis). All patients fulfilled the criteria for refractory schizophrenia according to the UK guidelines for the National Institute of Clinical Excellence (NICE). After all previous antipsychotic medications had run their course, the patients were started on clozapine according to a standardized titration and dosage schedule. Psychopathology was evaluated before the initiation of clozapine therapy and once every 4 weeks using the Brief Psychiatric Rating Scale (BPRS), the Scale for the Assessment for Positive Symptoms, and the Scale for the Assessment of Negative Symptoms. Of the TRS patients on clozapine, 55.7% achieved a clinical response, defined as at least a 20% decrease in BPRS. We observed a favorable effect of clozapine on both positive and negative symptoms. Logistic regression analysis showed that a good clozapine response was more likely when schizophrenia began at a later age, when negative symptoms were severe, and when patients had an early response at 4 weeks. A combination of demographic, baseline clinical, and acute treatment response variables may accurately predict response to clozapine in TRS. Priority should be given to initiating clozapine at the earliest phase of TRS, especially for patients with evident negative symptoms.Progress in Neuro-Psychopharmacology and Biological Psychiatry 09/2007; 31(6):1330-6. · 3.25 Impact Factor -
Article: Body dysmorphic disorder in patients with borderline personality disorder: prevalence, clinical characteristics, and role of childhood trauma
[show abstract] [hide abstract]
ABSTRACT: Objective: The prevalence of body dysmorphic disorder (BDD) in patients with borderline personality disorder (BPD) is unidentified. We hypothesised that BDD would be more common than realised in patients with BPD and comorbidity with BDD would result in a more severe clinical profile. Also, childhood trauma may play a predictive role in this association.Methods: The study included 70 BPD in-patients and 70 matched healthy controls. The subjects were evaluated with a comprehensive assessment battery using Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II) diagnostic tool for BDD, Global Assessment of Functioning, Traumatic Experiences Checklist and Hamilton Depression Rating Scale.Results: The prevalence of BDD was 54.3% in the borderline sample. The BPD patients with BDD had significantly lower overall functioning and higher levels of BPD pathology, childhood traumatic experiences, suicide attempts, substance abuse and self-mutilation than those without BDD. Traumatic experiences were significant predictor of comorbid BDD diagnosis in BPD patients.Conclusions: Our results suggest a relatively high prevalence of BDD among patients with BPD, and co-occurrence of BDD and BPD remains to be clarified. The additional diagnosis of BDD in patients with BPD may cause a more severe global illness, and these two disorders may share, at least partly, a common psychopathologic mechanism.Acta Neuropsychiatrica 08/2007; 20(1):33 - 40. · 0.58 Impact Factor -
Article: A case with euprolactinemic galactorrhea induced by escitalopram.
[show abstract] [hide abstract]
ABSTRACT: Endocrine and reproductive side effects of serotonergic antidepressants are uncommon and galactorrhea is only rarely mentioned among SSRI-related side effects. Perhaps through suppression of dopamine neurotransmission releasing prolactin from tonic inhibitor control of dopamine, serotonin-enhancing antidepressants may result in a rise in prolactin levels. However, we here describe a case of euprolactinemic galactorrhea induced by the SSRI escitalopram and discuss potential mechanisms of action.The International Journal of Psychiatry in Medicine 02/2007; 37(3):275-8. · 1.03 Impact Factor -
Article: Identification and posttraumatic stress disorder symptoms in rescue workers in the Marmara, Turkey, earthquake.
[show abstract] [hide abstract]
ABSTRACT: After the 1999 Marmara Turkey earthquake, 434 volunteer rescue workers and 154 soldiers who were control subjects completed the Questionnaire for Identification with Deceased Victims and the Impact of Event Scale-Revised (IES-R). Identification with the Deceased as Oneself, Identification with the Deceased as a Friend, Identification with the Deceased as a Family Member, and IES-R Intrusion, Avoidance, and Hyperarousal subscale scores were significantly higher in rescue workers. Identification-Self, Identification-Friend, and Identification-Family correlated with the IES-R subscale and total scores. The set of identification variables was significantly associated with group membership before, but not after, IES-R scores were controlled. Findings suggest that identification with deceased victims, not rescue work per se, is the risk factor of concern for posttraumatic stress disorder in rescue workers.Journal of Traumatic Stress 11/2005; 18(5):485-9. · 2.72 Impact Factor -
Article: Leptospirosis presenting with mania and psychosis: four consecutive cases seen in a military hospital in Turkey.
[show abstract] [hide abstract]
ABSTRACT: To present the clinical features and the treatment alternatives of manic and psychotic symptoms in patients with leptospirosis. Clinical observation and diagnosis of four cases with leptospirosis presenting with psychiatric symptoms. Leptospirosis diagnoses were established by recovery of the organism from culture, macroagglutination tests, and dark field microscopy in all cases. Leptospira ELISA-Ig M was also positive in all cases. Microagglutination tests were positive in case 1 and case 2. All of the cases were also screened for other possible medical, infectious, and neurological disorders that could account for their clinical symptoms. Patients were treated with a combination of antibiotics, antipsychotics and mood stabilizers. The presence of manic and psychotic symptoms with fever and high transaminase and/or CPK levels in high risk occupational groups during rainy periods should alert the physician to the possibility of leptospirosis. The psychiatric symptoms are sensitive to anti-psychotics and mood stabilizers but not to antimicrobial treatment, suggesting that the psychiatric picture may not be related to direct invasion of the central nervous system by the infectious agent.The International Journal of Psychiatry in Medicine 02/2005; 35(3):299-305. · 1.03 Impact Factor
