RESUMEN
While existing literature suggests that posttraumatic stress disorder (PTSD) is frequently undetected in routine clinical practice, the detection rate of PTSD in patients with a personality disorder (PD) has not been investigated. This study examined the point prevalence of PTSD and frequency of trauma-focused treatment in 204 outpatients with a PD. Data were derived from electronic patient files. Compared to the mean weighted prevalence of PTSD in the literature, the Mini International Neuropsychiatric Interview Plus (MINI-Plus) found lower rates of PTSD for the entire sample (29.2%), but not separately for patients with borderline PD (BPD; 33.3%) and patients with other PDs (26.9%). In addition, PTSD diagnoses following intake were less prevalent for PD patients overall (18.6%), BPD patients (27%), and patients with other PDs (13.8%). The present study provides preliminary evidence that PTSD might be underdiagnosed and consequently unmanaged in PD patients in clinical practice, suggesting that the recognition of PTSD among patients with PD needs improvement.

ABSTRACT: Sexual hallucinations are little known, yet often extremely burdening, phenomena. In this systematic review, we summarize what is known about their phenomenology, prevalence, etiopathology, ensuing distress, and treatment options. Sexual hallucinations can be experienced as genital or orgasmic sensations, although other sensory modalities can also be involved. With the notable exception of orgasmic auras in the context of epilepsy, sexual hallucinations tend to be distressing and embarrassing in nature. Our analysis of 79 studies (together describing 390 patients) indicates that sexual hallucinations are more frequent in women than in men, with a sex ratio of 1.4:1, and that they are most prevalent in schizophrenia spectrum disorders, with rates ranging from 1.4% in recently admitted patients to 44% in chronically hospitalized patients. Other underlying conditions include epilepsy, the incubus phenomenon (possibly the most prevalent cause in the general population, associated with sleep paralysis), narcolepsy, and sedative use. As regards the sedative context, we found more medicolegal than purely medical cases, which sadly underlines that not all sexually explicit sensations experienced in anesthesia practice are indeed hallucinations. In the absence of evidence-based treatment protocols for sexual hallucinations, practice-based guidelines tend to focus on the underlying condition. Further research is needed, especially in the fields of substance abuse, posttraumatic stress disorder, and borderline personality disorder, where only anecdotal information on sexual hallucinations is available. Moreover, awareness of sexual hallucinations among health professionals needs to be improved in order to facilitate counseling, diagnosis, and treatment.

BACKGROUND: Psychotic features have been part of the description of the borderline personality disorder (BPD) ever since the concept "borderline" was introduced. However, there is still much to learn about the presence and characteristics of delusions and about the stability of both hallucinations and delusions in patients with BPD. METHODS: A follow-up study was conducted in 326 BPD outpatients (median time between baseline and follow-up = 3.16 years). Data were collected via telephone (n = 267) and face-to-face interviews (n = 60) including the Comprehensive Assessment of Symptoms and History interview, Positive And Negative Syndrome Scale and the Psychotic Symptom Rating Scale. RESULTS: The point prevalence of delusions was 26%, with a median strong delusion conviction. For the group as a whole, the presence and severity of both hallucinations and delusions was found to be stable at follow-up. Participants with persistent hallucinations experienced more comorbid psychiatric disorders, and they differed from those with intermittent or sporadic hallucinations with their hallucinations being characterized by a higher frequency, causing a higher intensity of distress and more disruption in daytime or social activities. CONCLUSIONS: Delusions in patients with BPD occur frequently and cause distress. Contrary to tenacious beliefs, hallucinations and delusions in participants with BPD are often present in an intermittent or persistent pattern. Persistent hallucinations can be severe, causing disruption of life. Overall, we advise to refrain from terms such as "pseudo", or assume transience when encountering psychotic phenomena in patients with BPD, but rather to carefully assess these experiences and initiate a tailor-made treatment plan.

Background: Posttraumatic stress disorder (PTSD) is common in patients with personality disorders. This comorbidity is accompanied by a lower quality of life, and a higher risk of suicide attempts than patients with only one of these diagnoses. Objective: The aim of this systematic review and meta-analysis was to evaluate the scientific evidence of the efficacy of PTSD treatments for this population. Method: A literature search was performed from 1946 through June 2020. Standardized mean effect sizes of psychotherapy for PTSD were computed. Results: The literature search revealed that psychotherapy was the only intervention that was systematically explored. Fourteen studies were included. In 12 of these studies solely patients with borderline personality disorder participated. Analysis of the four RCTs showed a significant, moderate to high standardized effect size for reducing PTSD symptom severity (Hedges' g = 0.54), with effects being maintained at least 3 months (Hedges' g = 0.82). Effect sizes for all studies were also significant, with moderate to high standardized values for symptoms of PTSD (Hedges' g = 1.04). PTSD improvements were again maintained at 3-month follow-up and beyond (Hedges' g = 0.98). In addition, a significant decrease in symptoms of depression, anxiety, borderline symptoms, and PTSD in patients with borderline personality disorder could be revealed for all studies (Hedges' g 0.48-1.04). No increase in self-injurious behaviour, suicide attempts, or hospitalization was observed, while the mean weighted dropout rate during PTSD treatment was 17%. Conclusions: Psychotherapy for PTSD is efficacious and safe for patients with borderline personality disorder and should not be withheld from these vulnerable individuals.
Antecedentes: El trastorno de estrés postraumático (TEPT) es común en pacientes con trastornos de la personalidad. Esta comorbilidad se acompaña de una menor calidad de vida y un mayor riesgo de intentos de suicidio que los pacientes con solo uno de estos diagnósticos.Objetivo: El propósito de esta revisión sistemática y metanálisis fue evaluar la evidencia científica de la eficacia de los tratamientos de TEPT para esta población.Método: Se realizó una búsqueda bibliográfica desde 1946 hasta junio de 2020. Se calcularon los tamaños de efecto promedio estandarizados de la psicoterapia para el TEPT.Resultados: La búsqueda de la literatura reveló que la psicoterapia fue la única intervención explorada sistemáticamente. Se incluyeron catorce estudios. En doce de estos estudios participaron únicamente pacientes con trastorno límite de la personalidad. El análisis de los cuatro ECA mostró un tamaño de efecto estandarizado significativo, moderado a alto, para reducir la gravedad de los síntomas de TEPT (Hedges' g = 0.54), con efectos que se se mantenían al menos tres meses (Hedges' g = 0.82). Los tamaños del efecto para todos los estudios también fueron significativos, con valores estandarizados moderados a altos para síntomas de TEPT (Hedges' g = 1.04). Las mejoras del TEPT también se mantuvieron a los 3 meses de seguimiento y más allá (Hedges' g = 0.98). Adicionalmente, en todos los estudios podría ser revelada una disminución significativa de los síntomas de depresión, ansiedad, síntomas límite y trastorno de estrés postraumático en pacientes con trastorno límite de la personalidad (Hedges'g 0.48 1.04). No se observó aumento en el comportamiento autolesivo, intentos de suicidio u hospitalización, mientras que la tasa de abandono ponderada media durante el tratamiento del TEPT fue del 17%.Conclusiones: La psicoterapia para el trastorno de estrés postraumático es eficaz y segura para pacientes con trastorno límite de la personalidad y no debiera ser negada a estos individuos vulnerables.
RESUMEN
Although psychotic experiences are prevalent across many psychiatric, neurological, and medical disorders, investigation of these symptoms has largely been restricted to diagnostic categories. This study aims to examine phenomenological similarities and differences across a range of diagnoses. We assessed frequency, severity and phenomenology of psychotic experiences in 350 outpatients including; participants with schizophrenia spectrum disorders, hearing impairment, Parkinson's disease, Lewy Body Dementia, Alzheimer's disease, visual impairment, posttraumatic stress disorder, borderline personality disorder, and participants with recent major surgery. Psychotic phenomena were explored between these groups using the Questionnaire for Psychotic Experiences (QPE). Participants with major psychiatric disorders reported a combination of several psychotic experiences, and more severe experiences compared to all other disorders. Participants with recent major surgery or visual impairment experienced isolated visual hallucinations. Participants with hearing impairment reported isolated auditory hallucinations, whereas the neurodegenerative disorders reported visual hallucinations, occasionally in combination with hallucinations in another modality or delusions. The phenomenology between neurodegenerative disorders, and within major psychiatric disorders showed many similarities. Our findings indicate that the phenomenology of psychotic experiences is not diagnosis specific, but may rather point to the existence of various subtypes across diagnoses. These subtypes could have a different underlying etiology requiring specific treatment.

Auditory verbal hallucinations (AVH) are common in patients with borderline personality disorder (BPD). We examined two candidate mechanisms of AVH in patients with BPD, suggested to underlie sensory processing systems that contribute to psychotic symptoms in patients with schizophrenia; sensory gating (P50 ratio and P50 difference) and change detection (mismatch negativity; MMN). Via electroencephalographic recordings P50 amplitude, P50 ratio, P50 difference and MMN amplitude were compared between 23 borderline patients with and 25 without AVH, and 26 healthy controls. Borderline patients with AVH had a significantly lower P50 difference compared with healthy controls, whereas no difference was found between borderline patients without AVH and healthy controls. The groups did not differ on MMN amplitude. The impaired sensory gating in patients with borderline personality disorder who experience AVH implies that P50 sensory gating deficiencies may underlie psychotic vulnerability in this specific patient group. Patients with borderline personality disorder with or without AVH did not have problems with auditory change detection. This may explain why they are spared from the poor outcome associated with negative symptoms and symptoms of disorganization in patients with chronic schizophrenia.

Background: Trauma and posttraumatic stress disorder (PTSD) are prevalent in patients with personality disorders. Despite the established efficacy of eye movement desensitisation and reprocessing (EMDR) for PTSD, EMDR has barely been examined in patients with comorbid PTSD and personality disorders. Objective: The aim of this study was to explore what changes occur in symptom severity of PTSD, dissociative symptoms, insomnia, non-suicidal self-injurious behaviour and auditory verbal hallucinations in patients with personality disorders during treatment with EMDR. Method: This uncontrolled open feasibility study on EMDR for PTSD was an addition to treatment-as-usual for personality disorders. The outcome measures were the severity of PTSD symptoms, dissociation, insomnia, non-suicidal self-injury, and auditory verbal hallucinations. Results: Forty-seven participants (22 with a borderline personality disorder, 25 with other personality disorders) were included. A significant reduction in the severity of symptoms of PTSD, dissociation and insomnia was observed after EMDR treatment (median of four sessions), and 40% of the participants scored below the threshold for PTSD diagnosis. No differences in efficacy were found between patients with borderline personality disorder and other personality disorders. EMDR treatment was completed by 68% of the participants. Conclusions: The addition of EMDR techniques to treatment, as usual, may be beneficial in the treatment of PTSD in patients with personality disorders in order to reduce symptoms of PTSD, dissociation and insomnia. Although one-third of these patients did not complete the additional EMDR treatment, no severe complications (e.g. suicidal behaviour or hospitalisation) occurred. Controlled studies are needed to further investigate the validity of these findings.
Antecedentes: El trauma y el trastorno de estrés postraumático (TEPT) son prevalentes en pacientes con trastornos de personalidad. A pesar de la eficacia establecida de desensibilización y reprocesamiento por movimientos oculares (EMDR) para el trastorno por estrés postraumático, el EMDR apenas se ha examinado en pacientes con trastorno por estrés postraumático comórbido con trastornos de la personalidad.Objetivo: El objetivo de este estudio fue explorar qué cambios se producen en la gravedad de los síntomas del trastorno por estrés postraumático, los síntomas disociativos, el insomnio, las conductas autolesivas no suicidas y las alucinaciones verbales auditivas en pacientes con trastornos de la personalidad durante el tratamiento con EMDR.Método: En este estudio de factibilidad abierto no controlado de EMDR para el trastorno de estrés postraumático, EMDR fue agregado al tratamiento habitual para los trastornos de personalidad. Los resultados evaluados fueron la gravedad de los síntomas de trastorno de estrés postraumático, la disociación, el insomnio, la autolesión no suicida y las alucinaciones verbales auditivas.Resultados: Se incluyeron 47 participantes (22 con trastorno límite de la personalidad, 25 con otros trastornos de personalidad). Se observó una reducción significativa en la gravedad de los síntomas del trastorno de estrés postraumático, la disociación y el insomnio después del tratamiento con EMDR (mediana de cuatro sesiones), y el 40% de los participantes puntuaron por debajo del umbral para el diagnóstico de trastorno de estrés postraumático. No se encontraron diferencias en la eficacia entre los pacientes con trastorno límite de personalidad y otros trastornos de la personalidad. El tratamiento con EMDR fue completado por el 68% de los participantes.Conclusiones: La adición de técnicas EMDR al tratamiento habitual puede ser beneficiosa en el tratamiento del trastorno de estrés postraumático en pacientes con trastornos de personalidad para reducir los síntomas de trastorno de estrés postraumático, disociación e insomnio. Aunque un tercio de estos pacientes no completaron el tratamiento de EMDR adicional, no se presentaron complicaciones graves (por ejemplo, comportamiento suicida u hospitalización). Se requieren estudios controlados para investigar más a fondo la validez de estos hallazgos.
RESUMEN
Psychotic experiences are prevalent across a wide variety of psychiatric, neurological, and medical conditions. Yet current assessments are often designed for one disorder, or are limited in their examination of phenomenological features; this has hindered transdiagnostic research. This article describes an examination of the validity and reliability of the English version of a new assessment, the Questionnaire for Psychotic Experiences (QPE). This study aimed to use the QPE to examine hallucinations and delusions across a number of different conditions, and to ensure that the QPE had acceptable psychometric properties. An International Consortium on Hallucination Research working group, along with consumer groups, developed the 50-item QPE to assess the presence, severity, and phenomenology of hallucinations and delusions. Participants in the study who reported psychotic experiences included those with schizophrenia, schizoaffective disorder, bipolar affective disorder, and major depressive disorder, and those without a need for care (ie, nonclinical participants). There were 173 participants in total. Convergent and discriminant validity were assessed. Reliability was examined in terms of stability, equivalence, and internal consistency. The data confirmed that the QPE had good psychometric properties and could be put forward as an accepted measure of the transdiagnostic evaluation of psychotic experiences. Further validation is recommended with neurological and medical populations. Given its validity and reliability, comprehensive evaluation of psychotic phenomena, and relatively quick administration time, we propose that the QPE is a valuable instrument for both clinical and research settings.

Background: Auditory verbal hallucinations (AVH) are experienced more frequently by patients with borderline personality disorder (BPD) than previously assumed. However, consensus is lacking on how to treat them. Objective: To provide a systematic review of studies reporting on AVH in patients with BPD, with a focus on the efficacy of treatment of psychotic symptoms. Methods: For this review a systematic search was made in the PubMed and Ovid databases, and mean weighted prevalence rates, adjusted for sample size, were computed. Results: The search yielded 36 studies describing a total of 1,263 patients. Auditory hallucinations (including AVH) were reported in 27% of hospitalized BPD patients; AVH were reported in 25% of all patients and in 24% of outpatients. Of the hallucinating patients, 78% experienced AVH at least once per day, for a duration of several days to many years. On the whole, patients with BPD regarded their voices as malevolent and omnipotent in nature. Compared to patients with schizophrenia, the phenomenological characteristics of AVH were similar and the ensuing distress was equal or even higher, whereas scores for other positive symptoms were lower. The presence of AVH in BPD was associated with an increase of suicide plans and attempts, and more frequent hospitalization. Moreover, AVH in the context of BPD were associated with higher prevalence rates for post-traumatic stress disorder and emotional abuse. The efficacy of antipsychotics was investigated in 21 studies. Based on these studies, we conclude that both typical and atypical antipsychotics tend to have positive effects on AVH experienced in the context of BPD. The efficacy of cognitive-behavioral therapy and non-invasive brain stimulation has not yet been systematically assessed. Conclusions: These findings indicate that AVH experienced in the context of BPD are in need of proper diagnosis and treatment, and that antipsychotics tend to be beneficial in treating these (and other psychotic) symptoms.There is an urgent need for studies assessing the efficacy of cognitive-behavioral therapy and non-invasive brain stimulation in this underdiagnosed and undertreated group.

To establish the point prevalence of hallucinations in borderline personality disorder (BPD), telephone interviews were conducted with 324 outpatients diagnosed with BPD. Then a subgroup (n = 98) was interviewed in person to investigate the co-occurrence of these phenomena with other psychotic symptoms, comorbid psychiatric disorders, prior childhood adversities, and adult life stressors. For hallucinations in general a point prevalence of 43% was found, with rates for hallucinations in separate sensory modalities ranging from 8-21%. Auditory verbal hallucinations consisted mostly of verbal abuse and were generally experienced as distressing. A significant association was found between the severity of hallucinations on the one hand, and delusions and unusual thought content on the other; this association was absent for negative symptoms and disorganization. The presence of hallucinations also correlated with the number of comorbid psychiatric disorders, and with posttraumatic stress disorder (PTSD) specifically. Childhood emotional abuse and adult life stressors were also associated with hallucinations. The latter three associations suggest that patients with BPD might have an etiological mechanism in common with other patient/nonpatient groups who experience hallucinations. Based on these findings, we advise to treat PTSD and hallucinations when found to be present in patients with BPD.

BACKGROUND: Auditory verbal hallucinations (AVH) are experienced by 21-54% of patients diagnosed with a borderline personality disorder (BPD), and ensuing distress is often high. Little is known about the beliefs these patients foster about their voices, and the influence thereof on distress and need for hospitalisation. METHODS: In a convenience sample of 38 BPD outpatients with AVH, data were collected with the aid of the Psychotic Symptom Rating Scales (PSYRATS), Beliefs about Voices Questionnaire (BAVQ), Social Comparison Rating Scale (SCRS), and Voice Power Differential Scale (VPDS). RESULTS: The majority of patients with BPD who experience AVH rate their voices as malevolent and omnipotent, and higher in social rank than themselves. Moreover, their resistance against them tends to be high. These parameters correlate positively and significantly with high levels of distress experienced in relation to these AVH. The need for hospitalisation, in turn, is associated with high scores for omnipotence of the voices and distress due to AVH. However, these findings could not be confirmed in regression analyses. CONCLUSIONS: As negative beliefs can be altered with cognitive-behavioural therapy (CBT), we expect CBT to be beneficial in the treatment of AVH in BPD patients, whether or not in combination with antipsychotic medication.

A group of European experts was commissioned to establish guidelines on the therapeutic use of repetitive transcranial magnetic stimulation (rTMS) from evidence published up until March 2014, regarding pain, movement disorders, stroke, amyotrophic lateral sclerosis, multiple sclerosis, epilepsy, consciousness disorders, tinnitus, depression, anxiety disorders, obsessive-compulsive disorder, schizophrenia, craving/addiction, and conversion. Despite unavoidable inhomogeneities, there is a sufficient body of evidence to accept with level A (definite efficacy) the analgesic effect of high-frequency (HF) rTMS of the primary motor cortex (M1) contralateral to the pain and the antidepressant effect of HF-rTMS of the left dorsolateral prefrontal cortex (DLPFC). A Level B recommendation (probable efficacy) is proposed for the antidepressant effect of low-frequency (LF) rTMS of the right DLPFC, HF-rTMS of the left DLPFC for the negative symptoms of schizophrenia, and LF-rTMS of contralesional M1 in chronic motor stroke. The effects of rTMS in a number of indications reach level C (possible efficacy), including LF-rTMS of the left temporoparietal cortex in tinnitus and auditory hallucinations. It remains to determine how to optimize rTMS protocols and techniques to give them relevance in routine clinical practice. In addition, professionals carrying out rTMS protocols should undergo rigorous training to ensure the quality of the technical realization, guarantee the proper care of patients, and maximize the chances of success. Under these conditions, the therapeutic use of rTMS should be able to develop in the coming years.

With an increase of the number of studies exploring repetitive transcranial magnetic stimulation (rTMS) for the treatment of auditory verbal hallucinations (AVH), an update is provided on the efficacy of different paradigms. A literature search was performed from 1966 through April 2013. Twenty-five randomized controlled trials using the severity of AVH or psychosis as outcome measures were included. Standardized mean weighted effect sizes were computed; a qualitative review of the literature was performed to assess the effects of various rTMS paradigms. rTMS versus sham treatment for AVH yielded a mean weighted effect size of .44. No significant mean weighted effect size was found for the severity of psychosis (i.e., .21). For patients with medication-resistant AVH, the mean weighted effect size was .45. rTMS applied at the left temporoparietal area with a frequency of 1 Hz yielded a moderate mean weighted effect size of .63, indicating superiority of this paradigm. Various other paradigms failed to show superior effects. rTMS applied at the right temporoparietal area was not superior to sham treatment. rTMS, especially when applied at the left temporoparietal area with a frequency of 1 Hz, is effective for the treatment of AVH, including in patients with medication-resistant AVH. The results for other rTMS paradigms are disappointing thus far. A next step should be to explore the effects of rTMS in medication-free individuals, for example, during the initial phases of psychosis, and in patients with diagnoses other than schizophrenia who do not have comorbid psychotic symptoms.

Despite a growing interest in auditory verbal hallucinations (AVHs) in different clinical and nonclinical groups, the phenomenological characteristics of such experiences have not yet been reviewed and contrasted, limiting our understanding of these phenomena on multiple empirical, theoretical, and clinical levels. We look at some of the most prominent descriptive features of AVHs in schizophrenia (SZ). These are then examined in clinical conditions including substance abuse, Parkinson's disease, epilepsy, dementia, late-onset SZ, mood disorders, borderline personality disorder, hearing impairment, and dissociative disorders. The phenomenological changes linked to AVHs in prepsychotic stages are also outlined, together with a review of AVHs in healthy persons. A discussion of key issues and future research directions concludes the review.

This article reviews the treatment of hallucinations in schizophrenia. The first treatment option for hallucinations in schizophrenia is antipsychotic medication, which can induce a rapid decrease in severity. Only 8% of first-episode patients still experience mild to moderate hallucinations after continuing medication for 1 year. Olanzapine, amisulpride, ziprasidone, and quetiapine are equally effective against hallucinations, but haloperidol may be slightly inferior. If the drug of first choice provides inadequate improvement, it is probably best to switch medication after 2-4 weeks of treatment. Clozapine is the drug of choice for patients who are resistant to 2 antipsychotic agents. Blood levels should be above 350-450 µg/ml for maximal effect. For relapse prevention, medication should be continued in the same dose. Depot medication should be considered for all patients because nonadherence is high. Cognitive-behavioral therapy (CBT) can be applied as an augmentation to antipsychotic medication. The success of CBT depends on the reduction of catastrophic appraisals, thereby reducing the concurrent anxiety and distress. CBT aims at reducing the emotional distress associated with auditory hallucinations and develops new coping strategies. Transcranial magnetic stimulation (TMS) is capable of reducing the frequency and severity of auditory hallucinations. Several meta-analyses found significantly better symptom reduction for low-frequency repetitive TMS as compared with placebo. Consequently, TMS currently has the status of a potentially useful treatment method for auditory hallucinations, but only in combination with state of the art antipsychotic treatment. Electroconvulsive therapy (ECT) is considered a last resort for treatment-resistant psychosis. Although several studies showed clinical improvement, a specific reduction in hallucination severity has never been demonstrated.

BACKGROUND: Alice in Wonderland syndrome (AIWS) is a rare cluster of CNS symptoms characterized by visual distortions (i.e. metamorphopsias), body image distortions, time distortions, and déjà experiences. Verbal auditory hallucinations (VAHs) are the most prevalent type of hallucination in adults with or without a history of psychiatric illness. Here, we report the case of a woman with AIWS, long-lasting VAHs, and various additional perceptual and mood symptoms. METHODS: Semi-structured interviews were used to assess symptoms, and functional MRI (fMRI) was employed to localize cerebral activity during self-reported VAHs. Treatment consisted of repetitive transcranial magnetic stimulation (rTMS) at a frequency of 1 Hz at T3P3, overlying Brodmann's area 40. RESULTS: Activation during VAHs was observed bilaterally in the basal ganglia, the primary auditory cortex, the association auditory cortex, the temporal poles, and the anterior cingulated gyrus. The left and right inferior frontal gyri (Broca's area and its contralateral homologue) were involved, along with the dorsolateral prefrontal cortex. Interestingly, synchronized activation was observed in the primary visual cortex (areas V1 and V2), and the bilateral dorsal visual cortex. The higher visual association cortex also showed significant, but less prominent, activation. During the second week of rTMS treatment, not only the VAHs, but also the other sensory deceptions/distortions and mood symptoms showed complete remission. The patient remained free of any symptoms during a 4-month follow-up phase. After 8 months, when many of the original symptoms had returned, a second treatment phase with rTMS was again followed by complete remission. CONCLUSIONS: This case indicates that VAHs and metamorphopsias in AIWS are associated with synchronized activation in both auditory and visual cortices. It also indicates that local rTMS treatment may have global therapeutic effects, suggesting an effect on multiple brain regions in a distributed network. Although a placebo effect cannot be ruled out, this case warrants further investigation of the effects of rTMS treatment in AIWS.

BACKGROUND: Several studies have applied low-frequency repetitive transcranial magnetic stimulation (rTMS) directed at the left temporoparietal area (TP) for the treatment of auditory verbal hallucinations (AVH), but findings on efficacy are inconsistent. Furthermore, recent functional magnetic resonance imaging (fMRI) studies indicate that the left TP is not a general focus of activation during the experience of AVH. The aims of this study are twofold: to investigate the effects of rTMS on AVH in a double blind, randomized, sham-controlled study; and to investigate whether the efficacy can be improved when rTMS is guided by individual fMRI scans of hallucinatory activation. METHODS: Sixty-two patients with medication-resistant AVH were randomized over three conditions: rTMS targeted at the area of maximal hallucinatory activation calculated from individual fMRI scans during AVH, rTMS directed at the left TP, and sham treatment. Repetitive TMS was applied during 15 sessions of 20 min each, at 1 Hz and 90% of the individual motor threshold. The severity of AVH and other psychotic symptoms were monitored during treatment and 3-month follow-up, with the Auditory Hallucination Rating Scale, the Positive and Negative Syndrome Scale, and the Psychotic Symptom Rating Scales. RESULTS: The effects of fMRI-guided rTMS and left TP rTMS on the severity of AVH were comparable to those of sham treatment. No differences in severity of general psychotic symptoms were found among the three treatment conditions. CONCLUSIONS: Low-frequency rTMS administered to the left TP or to the site of maximal hallucinatory activation is not more effective for medication-resistant AVH than sham treatment.

OBJECTIVE: Repetitive transcranial magnetic stimulation (rTMS) is a safe treatment method with few side effects. However, efficacy for various psychiatric disorders is currently not clear. DATA SOURCES: A literature search was performed from 1966 through October 2008 using PubMed, Ovid Medline, Embase Psychiatry, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, and PsycINFO. The following search terms were used: transcranial magnetic stimulation, TMS, repetitive TMS, psychiatry, mental disorder, psychiatric disorder, anxiety disorder, attention-deficit hyperactivity disorder, bipolar disorder, catatonia, mania, depression, obsessive-compulsive disorder, psychosis, posttraumatic stress disorder, schizophrenia, Tourette's syndrome, bulimia nervosa, and addiction. STUDY SELECTION: Data were obtained from randomized, sham-controlled studies of rTMS treatment for depression (34 studies), auditory verbal hallucinations (AVH, 7 studies), negative symptoms in schizophrenia (7 studies), and obsessive-compulsive disorder (OCD, 3 studies). Studies of rTMS versus electroconvulsive treatment (ECT, 6 studies) for depression were meta-analyzed. DATA EXTRACTION: Standardized mean effect sizes of rTMS versus sham were computed based on pretreatment-posttreatment comparisons. DATA SYNTHESIS: The mean weighted effect size of rTMS versus sham for depression was 0.55 (P < .001). Monotherapy with rTMS was more effective than rTMS as adjunctive to antidepressant medication. ECT was superior to rTMS in the treatment of depression (mean weighted effect size -0.47, P = .004). In the treatment of AVH, rTMS was superior to sham treatment, with a mean weighted effect size of 0.54 (P < .001). The mean weighted effect size for rTMS versus sham in the treatment of negative symptoms in schizophrenia was 0.39 (P = .11) and for OCD, 0.15 (P = .52). Side effects were mild, yet more prevalent with high-frequency rTMS at frontal locations. CONCLUSIONS: It is time to provide rTMS as a clinical treatment method for depression, for auditory verbal hallucinations, and possibly for negative symptoms. We do not recommend rTMS for the treatment of OCD.
