Essential fatty acids (EFAs) have been shown to benefit patients with depression, schizophrenia and dementia. More recently, their role in disorders characterised by impulsivity has attracted some attention. The psychiatric conditions of attention-deficit hyperactivity disorder and borderline personality disorder as well as the phenomena of deliberate self-harm and violence have been ameliorated by the supplementation of EFAs in a number of recent clinical trials. This paper summarises the burgeoning clinical and basic research indicating the existence of significant deficits of EFAs in impulsivity disorders and the supplementation studies of EFAs in these diverse conditions, all of which remain a major therapeutic challenge.

Magnetic resonance imaging (MRI) has opened a new window to the brain. Measuring hippocampal volume with MRI has provided important information about several neuropsychiatric disorders. We reviewed the literature and selected all English-language, human subject, data-driven papers on hippocampal volumetry, yielding a database of 423 records. Smaller hippocampal volumes have been reported in epilepsy, Alzheimer's disease, dementia, mild cognitive impairment, the aged, traumatic brain injury, cardiac arrest, Parkinson's disease, Huntington's disease, Cushing's disease, herpes simplex encephalitis, Turner's syndrome, Down's syndrome, survivors of low birth weight, schizophrenia, major depression, posttraumatic stress disorder, chronic alcoholism, borderline personality disorder, obsessive-compulsive disorder, and antisocial personality disorder. Significantly larger hippocampal volumes have been correlated with autism and children with fragile X syndrome. Preservation of hippocampal volume has been reported in congenital hyperplasia, children with fetal alcohol syndrome, anorexia nervosa, attention-deficit and hyperactivity disorder, bipolar disorder, and panic disorder. Possible mechanisms of hippocampal volume loss in neuropsychiatric disorders are discussed.

The aim of this study was to investigate the occurrence of dissociative symptoms in patients with a schizophrenic disorder. The pattern of dissociative experiences was examined in a group of patients with a diagnosis of the schizophrenia spectrum disorder (n = 26; mean age 27.9 years), and a group of patients with a diagnosis of borderline personality disorder (n = 26; mean age 24.0 years) was compared with normal controls of the general population (n = 1,056; mean age 18.7 years). The degree of self-reported dissociative symptoms was measured using the German version of the Dissociative Experiences Scales. The dissociation scores were significantly higher among patients with a diagnosis of borderline personality disorder compared to the group of schizophrenic patients and to the control group. There was no difference in the degree of reported dissociative experiences between the group of schizophrenic patients and the normal volunteers. An analysis of the subdimensions (dissociative amnesia, absorption/imaginative involvement, depersonalization/derealization) of the scale revealed the same strong distinctions between the investigated groups. There was no evidence that dissociative symptoms reflect a specific vulnerability in young schizophrenic patients.

Family psychoeducation programs have emerged as a strongly supported evidence-based practice in the treatment of schizophrenia and bipolar disorder. Over 30 randomized clinical trials demonstrated that psychoeducation programs reduce relapse, improve symptomatic recovery, and enhance psychosocial and family outcomes. Recent work supports family psychoeducation strategies for other disorders, including major depression, obsessive-compulsive disorder, and borderline personality disorder. This review summarizes the research evidence supporting prominent models of family psychoeducation. Professional and peer-led family education programs are also reviewed and differentiated from family psychoeducation. Directions for future research studies to enhance the evidence base and inform treatment recommendations are proposed. Finally, strategies for implementation of family psychoeducation in routine clinical practice are discussed.

One of the most serious and difficult-to-treat conditions in child and adolescent psychiatry is self-injurious behavior (SIB). SIB can be associated with a number of psychiatric disorders, including mental retardation, schizophrenia, borderline personality disorder, pervasive developmental disorders, stereotypic movement disorder, and Tourette's Disorder. A variety of neurosurgical procedures have been used to treat both intractable SIB and severe Tourette's Disorder. Understandably, there are few reports concerning psychosurgery in children and adolescents for any condition or disorder. This report describes the use of cingulotomy and subsequent limbic leucotomy in an adolescent boy with Tourette's Disorder for SIB. His repetitive and medically serious SIB and failure of all other treatments prompted this intervention after careful, comprehensive review and discussion. Following the second surgery, the severity and frequency of his SIB were reduced.

This is a report on a 37-patient continuation study of the open ended, Omega-3 Fatty Acid (O-3FA) add-on study. Subjects consisted of the original 19 patients, along with 18 new patients recruited and followed in the same fashion as the first nineteen. Subjects carried a DSM-IV-TR diagnosis of Bipolar Disorder and were visiting a Mood Disorder Clinic regularly through the length of the study. At each visit, patients' clinical status was monitored using the Clinical Monitoring Form. Subjects reported on the frequency and severity of irritability experienced during the preceding ten days; frequency was measured by way of percentage of days in which subjects experienced irritability, while severity of that irritability was rated on a Likert scale of 1-4 (if present). The irritability component of Young Mania Rating Scale (YMRS) was also recorded quarterly on 13 of the 39 patients consistently. Patients had persistent irritability despite their ongoing pharmacologic and psychotherapy. Omega-3 Fatty Acid intake helped with the irritability component of patients suffering from bipolar disorder with a significant presenting sign of irritability. Low dose (1 to 2 grams per day), add-on O-3FA may also help with the irritability component of different clinical conditions, such as schizophrenia, borderline personality disorder and other psychiatric conditions with a common presenting sign of irritability.

BPD is often associated with cognitive deficits that tend to be present regardless of mood state. Greater impairments tend to be seen in BPD patients who are older, have an early onset of the disease, and suffer a more severe course of illness. The literature also suggests that cognitive deficits are present early in patients with BPD and may be cumulative, showing an association with the number of affective (particularly depressed) episodes over time. Cognitive deficits in BPD may share some common characteristics with those seen in patients with schizophrenia, although the latter tend to show much greater and generalized cognitive impairment. For example, unlike patients with schizophrenia, patients with BPD typically do not score lower than normal persons on measures of global intellectual ability. There also is not overwhelming evidence of laterality or localization of cognitive deficits in BPD, although debate in the literature continues. More visuospatial deficits tend to be found in BPD and UPD than in schizophrenia, thereby raising the possibility of greater involvement of right hemisphere systems in mood disorders. In general, despite variability across investigations, deficits in executive functioning, episodic memory,sustained concentration, and, to a lesser extent, visuospatial skills seem to be the most consistent areas of impairment in BPD. Just as neuroimaging anomalies have been well documented in schizophrenia, structural brain abnormalities have been noted in BPD,most commonly involving the basal ganglia or white matter. Specific comparisons of cerebral atrophy and ventricular size between patients with schizophrenia and BPD have not been definitive, making it difficult to draw conclusions about structural brain abnormalities that might be specific to BPD. Nonetheless, there is enough evidence to suggest that white-matter abnormalities are reported with a greater frequency in BPD patients than in patients with UPD or schizophrenia. Functional neuro-imaging studies of mood disorders have indicated that the frontal cortex,basal ganglia, and temporal lobes are involved. The relationships between neuroimaging and neurocognitive abnormalities in BPD are worthy of additional investigation. Clearly, efforts directed toward phenotyping neuropsychiatric disorders using such measures, in addition to other clinical, neuroimaging, neurophysiologic, and genotypic information, may yield important insights into the development, nature, and course of illness. It is hoped that this understanding will lead to better identification of individuals who may be prone to greater cognitive impairment or decline and those who might be more responsive to specific treatments.

This study evaluates the validity and the reliability of a new instrument developed to assess the psychotic spectrum: the Structured Clinical Interview for the Psychotic Spectrum (SCI-PSY). The instrument is based on a spectrum model that emphasizes soft signs, low-grade symptoms, subthreshold syndromes, as well as temperamental and personality traits comprising the clinical and subsyndromal psychotic manifestations. The items of the interview include, in addition to a subset of the DSM-IV criteria for psychotic syndromes, a number of features derived from clinical experience and from a review of the phenomenological descriptions of psychoses. Study participants were enrolled at 11 Italian Departments of Psychiatry located at 9 sites and included 77 consecutive patients with schizophrenia or schizoaffective disorder, 66 with borderline personality disorder, 59 with psychotic mood disorders, 98 with non-psychotic mood disorders and 57 with panic disorder. A comparison group of 102 unselected controls was enrolled at the same sites. The SCI-PSY significantly discriminated subjects with any psychiatric diagnosis from controls and subjects with from those without psychotic disorders. The hypothesized structure of the instrument was confirmed empirically.

The importance of omega-3 fatty acids for physical health is now well recognised and there is increasing evidence that omega-3 fatty acids may also be important to mental health. The two main omega-3 fatty acids in fish oil, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have important biological functions in the CNS. DHA is a major structural component of neuronal membranes, and changing the fatty acid composition of neuronal membranes leads to functional changes in the activity of receptors and other proteins embedded in the membrane phospholipid. EPA has important physiological functions that can affect neuronal activity. Epidemiological studies indicate an association between depression and low dietary intake of omega-3 fatty acids, and biochemical studies have shown reduced levels of omega-3 fatty acids in red blood cell membranes in both depressive and schizophrenic patients. Five of six double-blind, placebo-controlled trials in schizophrenia, and four of six such trials in depression, have reported therapeutic benefit from omega-3 fatty acids in either the primary or secondary statistical analysis, particularly when EPA is added on to existing psychotropic medication. Individual clinical trials have suggested benefits of EPA treatment in borderline personality disorder and of combined omega-3 and omega-6 fatty acid treatment for attention-deficit hyperactivity disorder. The evidence to date supports the adjunctive use of omega-3 fatty acids in the management of treatment unresponsive depression and schizophrenia. As these conditions are associated with increased risk of coronary heart disease and diabetes mellitus, omega-3 fatty acids should also benefit the physical state of these patients. However, as the clinical research evidence is preliminary, large, and definitive randomised controlled trials similar to those required for the licensing of any new pharmacological treatment are needed.

Personality disorders are usually treated with either psychodynamic or supportive psychotherapy, with psychotropic medication often used as an adjunctive treatment. However, patients with personality disorders pose special treatment issues, because their problems are pervasive and long-standing and they have entrenched deficits in many areas of functioning. In this article, the authors consider the role of skills training in the treatment of personality disorders. They describe a two-pronged approach to the treatment of personality disorders based on a model of deficit compensation. Because skills training has only been investigated in a very limited way in personality disorders, the authors first review research on the use of skills training in Axis I disorders as background for a discussion of ways in which skills training may be applicable to the treatment of Axis II disorders. They describe a number of skills training approaches (social skills training, anger management, and conversational skills) that can be used for a variety of different Axis I disorders. Skills training approaches that are targeted to specific types of disorders (substance use disorders, schizophrenia, anxiety disorders, adolescent problems) are also described. The authors then review what is known about the use of skills training in borderline personality disorder and avoidant personality disorder, and propose skills training approaches that may be useful for patients with paranoid personality disorder and antisocial personality disorder. Case examples are provided to demonstrate how skills training for personality disorders can be applied in clinical practice.
