Five pedigrees of bipolar patients with at least two bipolar subjects on two generations have been identified in psychiatric departments of Nantes, Montpellier and Challans for linkage studies. In each pedigree, it was found one or more patients suffering from other conditions, like Borderline personality, Anorexia-bulimia, Mental retardation with dysmorphia, and Panic disorders. Mood disorders spectrum and therapeutic implications are discussed.

This study examines gender and racial differences among Missouri insanity acquittees, which included 42 African American females, 279 African American males, 63 Caucasian females, and 458 Caucasian males. Significant differences across the four groups were not found in age, current marital status, a diagnosis of borderline intellectual functioning/mental retardation, committing crimes of assault and burglary, and whether insanity acquittees ever received conditional releases to reside in the community. Some variations across the four gender/race categories were related to race (diagnoses of schizophrenia, mood disorders, and other Axis I diagnoses), but variations were more frequently related to gender (whether ever married; diagnoses of substance abuse, sexual disorders, antisocial personality disorder, borderline personality disorder, and any personality disorder; committing crimes of murder, sexual offenses, and serious offenses; and current residential status). African American males were identified as being an at-risk population. They were the most likely to have a schizophrenia diagnosis, a substance abuse diagnosis, an antisocial personality disorder diagnosis, and to be hospitalized on the survey date. Implications for treatment and future research are explored.

Neurological and psychiatric illnesses are among the most common and most serious health problems in developed societies. The most promising advances in neurological and psychiatric diseases will require advances in neuroscience for their elucidation, prevention, and treatment. Technical advances have improved methods for identifying brain regions involved during various types of cognitive activity, for tracing connections between parts of the brain, for visualizing individual neurons in living brain preparations, for recording the activities of neurons, and for studying the activity of single-ion channels and the receptors for various neurotransmitters. The most significant advances in the past 20 years have come from the application to the nervous system of molecular genetics and molecular cell biology. Discovery of the monogenic disorder responsible for Huntington disease and understanding its pathogenesis can serve as a paradigm for unraveling the much more complex, polygenic disorders responsible for such psychiatric diseases as schizophrenia, manic depressive illness, and borderline personality disorder. Thus, a new degree of cooperation between neurology and psychiatry is likely to result, especially for the treatment of patients with illnesses such as autism, mental retardation, cognitive disorders associated with Alzheimer and Parkinson disease that overlap between the 2 disciplines.

Differences in assessment and classification procedures of many mixed-handedness studies have made comparison of findings difficult. In the present study, "narrow" and "broad" definitions of mixed-handedness were investigated using the Annett Handedness Questionnaire in patients with schizophrenia (n=68), panic disorder (n=62), borderline personality disorder (n=35), heroin addiction (n=54), and mental retardation (n=33) in comparison with 944 controls. According to the "narrow" definition of mixed-handedness, an excess of mixed-handedness was observed in patients with borderline personality disorder and mental retardation. An excess of nonmixed-handedness was found in patients with panic disorder. According to the "broad" definition of mixed-handedness, an excess of mixed-handedness was observed in patients with mental retardation, in the total sample of psychiatric patients (n=252), and in the schizophrenic patients. Thus, we can conclude that different mixed-handedness definitions can be associated with different results. Furthermore, we suggest that the neurotic part of the present psychopathology spectrum tends to be related to an excess of normal or nonmixed-handedness, and the psychotic as well as the organic portion is associated with an excess of mixed-handedness, regardless of the definition of mixed-handedness used.

Although there is no universally accepted definition of compulsive sexual behaviour (CSB), the term is generally used to indicate excessive sexual behaviour or sexual cognitions that lead to subjective distress, social or occupational impairment, or legal and financial consequences. Similar to impulse control disorders, CSB is characterized by a failure to resist the impulse for sex. Opioid antagonists have been effective in treating urge-driven disorders, such as pathological gambling disorder, alcoholism, borderline personality disorder with self-injurious behaviour, cocaine abuse, mental retardation with self-injurious behaviour and eating disorders. Based upon the efficacy of opioid antagonists in treating disorders associated with urges, we hypothesized that naltrexone would reduce both the urges associated with CSB and therefore reduce the sexual behaviour. We present two case reports of individuals with CSB treated successfully with naltrexone, a novel treatment for CSB. In both cases, symptoms dramatically decreased and psychosocial functioning improved with the use of naltrexone. Although more research is needed to determine the mechanism that leads to the excessive sexual behaviour in individuals with CSB, the present case reports suggest that naltrexone may be effective in treating some cases of CSB.

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.

We report on a 7-year-old girl with severe mental retardation (MR), autism, micro-brachycephaly, generalized muscle hypotonia with distal hypotrophy of lower limbs, scoliosis and facial dysmorphisms. Array-CGH analysis identified a 1.1 Mb deletion of chromosome Xq22.1. Further analysis demonstrated that the deletion was inherited from her mother who showed mild MR, short stature, brachycephaly, epilepsy and a Borderline Personality Disorder. Microsatellite segregation analysis revealed that the rearrangement arose de novo in the mother on the paternal X chromosome. The deleted Xq22.1 region contains part of the NXF gene cluster which is involved in mRNA nuclear export and metabolism. Among them, the NXF5 gene has already been linked to mental retardation whereas NXF2 protein has been recently found to be partner of FMRP in regulating Nxf1 mRNA stability in neuronal cells. The dosage imbalance of NXF5 and NXF2 genes may explain the severe phenotype in our patient.

The authors present the results from a 3-year follow-up among 170 patients who had participated in the original randomized study, which consisted of three treatment conditions: (a) 3-month abandonment psychotherapy (AP) delivered by certified psychotherapists, (b) AP delivered by nurses, and (c) treatment as usual in a psychiatric crisis center. All subjects were recruited at the emergency room after a suicide attempt and met diagnostic criteria for borderline personality disorder and major depression. Psychotic symptoms, bipolar disorder, and mental retardation were exclusion criteria. At 3-year follow-up, 134 (78.8%) subjects had blind, reliable assessment by clinical psychologists. The intent-to-treat analysis indicated that those patients who had received AP during acute treatment had better global functioning, improved work adjustment, and less unemployment/disability at 3-year follow-up. No differences were found as a function of type of therapist delivering AP. The data confirm that short-term AP gains in psychosocial functioning are sustained over the longer term.
