A comprehensive search and review of literature, documents, publications and other material written since 1970, relevant to American Indian mental health research, was completed in order to generate a list of research and of training needs. A content analysis of this literature enabled a synthesis which describes important biopsychosocial issues faced by American Indian communities, gaps in past and current research efforts, specific problems in past research, and recommendations in each of these areas with regards to future research possibilities and needs. The portion of the analysis presented in this paper deals with American Indian infants, preschoolers, children and adolescents. In order of presentation, the specific issue domains dealt with include: otitis media, fetal alcohol syndrome, abuse and neglect, failure-to-thrive/autism/enuresis, which are examined together (early development) in terms of research gaps; and neurosensory disorders/developmental disabilities/handicapping conditions/school-related problems, foster care and adoption, self-concept/identity, conduct disorders/delinquency, drug and alcohol use, and suicide and depression, which are examined (school-age children and adolescents) in relation to research gaps and needs.

The presentation of affective disorders in people with autism and autistic-like disorders is discussed based upon a review of 17 published cases. Half of the patients were female and almost all of the patients had IQs in the mentally retarded range. 35% of the patients had the onset of affective disorder in childhood. Of the cases mentioning family history, 50% had a family history of affective disorder or suicide. Changes in mood, self-attitude, and vital sense were rarely reported by the patients. A change in mood, attitude toward self and others, and vegetative changes were inferred based on the observations of others. Difficulties in diagnosing affective disorders in autistic people are presented and suggestions are made for diagnosis, treatment, and research.

The serotonin system modulates affective, cognitive and behavioral processes. A key molecular structure of this system, the serotonin transporter (SERT) gene, has been associated with many human behaviors, both normal and pathological. This article aim is a comprehensive overview of the human behavioral features influenced by SERT gene variants and to suggest some comprehensive hypotheses. In particular, the SERTPR insertion/deletion polymorphism has been related to hippocampal volume and amygdala response and it has been found to influence anxiety-related personality traits and anxiety disorders; in mood disorders it showed some influences on age at onset, periodicity, illness recurrence, rapid cycling, antidepressants response and depressive reaction to stressful life events. Psychosomatic disorders, suicide, alcoholism, smoking, eating disorders, attention deficit hyperactivity disorders and autism have been also found to be related to SERTPR variants. SERT gene variants seem therefore to modulate a wide range of aspects in both normal and affected individuals, many of which are possibly due to indirect correlations between such human features.

Death by suicide occurs in a disproportionate percentage of individuals with anorexia nervosa (AN), with a standardized mortality ratio indicating a 57-fold greater risk of death from suicide relative to an age-matched cohort. Longitudinal studies indicate impaired social functioning increases risk for fatal outcomes, while social impairment persists following recovery. Study of social cognition in AN may elucidate impaired processes that may influence therapeutic efficacy. Symptoms of autism spectrum disorders (ASD) are overrepresented in those who evidence a chronic course. Relative to that in AN, social information processing in ASD is well characterized and may inform systematic study in AN. This article (a) reviews impaired interpersonal processes in AN, (b) compares the phenotype of AN with that of ASD, (c) highlights deficits of social cognitive disturbance in ASD relative to AN, and (d) proposes a new framework to understand the interaction of individuals with AN with their social context.

According to the Diagnostic and Statistical Manual of Mental Disorders, 4 out of the 10 leading causes of disability in the US and other developed countries are mental disorders. Major depression, bipolar disorder, schizophrenia, and obsessive compulsive disorder (OCD) are among the most common mental disorders that currently plague numerous countries and have varying incidence rates from 26 percent in America to 4 percent in China. Though some of this difference may be attributable to the manner in which individual healthcare providers diagnose mental disorders, this noticeable distribution can be also explained by studies which show that a lack of certain dietary nutrients contribute to the development of mental disorders. Notably, essential vitamins, minerals, and omega-3 fatty acids are often deficient in the general population in America and other developed countries; and are exceptionally deficient in patients suffering from mental disorders. Studies have shown that daily supplements of vital nutrients often effectively reduce patients' symptoms. Supplements that contain amino acids also reduce symptoms, because they are converted to neurotransmitters that alleviate depression and other mental disorders. Based on emerging scientific evidence, this form of nutritional supplement treatment may be appropriate for controlling major depression, bipolar disorder, schizophrenia and anxiety disorders, eating disorders, attention deficit disorder/attention deficit hyperactivity disorder (ADD/ADHD), addiction, and autism. The aim of this manuscript is to emphasize which dietary supplements can aid the treatment of the four most common mental disorders currently affecting America and other developed countries: major depression, bipolar disorder, schizophrenia, and obsessive compulsive disorder (OCD). Most antidepressants and other prescription drugs cause severe side effects, which usually discourage patients from taking their medications. Such noncompliant patients who have mental disorders are at a higher risk for committing suicide or being institutionalized. One way for psychiatrists to overcome this noncompliance is to educate themselves about alternative or complementary nutritional treatments. Although in the cases of certain nutrients, further research needs to be done to determine the best recommended doses of most nutritional supplements, psychiatrists can recommend doses of dietary supplements based on previous and current efficacious studies and then adjust the doses based on the results obtained.

Alternative pre-mRNA splicing is a major mechanism by which the proteomic diversity of eukaryotic genomes is amplified. Much akin to neuropsychiatric disorders themselves, alternative splicing events can be influenced by genetic, developmental, and environmental factors. Here, we review the evidence that abnormalities of splicing may contribute to the liability toward these disorders. First, we introduce the phenomenon of alternative splicing and describe the processes involved in its regulation. We then review the evidence for specific splicing abnormalities in a wide range of neuropsychiatric disorders, including psychotic disorders (schizophrenia), affective disorders (bipolar disorder and major depressive disorder), suicide, substance abuse disorders (cocaine abuse and alcoholism), and neurodevelopmental disorders (autism). Next, we provide a theoretical reworking of the concept of "gene-focused" epidemiologic and neurobiologic investigations. Lastly, we suggest potentially fruitful lines for future research that should illuminate the nature, extent, causes, and consequences of alternative splicing abnormalities in neuropsychiatric disorders.

Suicide is the most important incident in psychiatric disorders. Psychological pain and empathy to pain involves a neural network that involves the anterior cingulate cortex (ACC) and the anterior insula (AI). At the neuronal level, little is known about how complex emotions such as shame, guilt, self-derogation and social isolation, all of which feature suicidal behavior, are represented in the brain. Based on the observation that the ACC and the AI contain a large spindle-shaped cell type, referred to as von Economo neuron (VEN), which has dramatically increased in density during human evolution, and on growing evidence that VENs play a role in the pathophysiology of various neuropsychiatric disorders, including autism, psychosis and dementia, we examined the density of VENs in the ACC of suicide victims. The density of VENs was determined using cresyl violet-stained sections of the ACC of 39 individuals with psychosis (20 cases with schizophrenia, 19 with bipolar disorder). Nine subjects had died from suicide. Twenty specimen were available from the right, 19 from the left ACC. The density of VENs was significantly greater in the ACC of suicide victims with psychotic disorders compared with psychotic individuals who died from other causes. This effect was restricted to the right ACC. VEN density in the ACC seems to be increased in suicide victims with psychosis. This finding may support the assumption that VEN have a special role in emotion processing and self-evaluation, including negative self-appraisal.

Though still in infancy, the field of psychiatric genetics holds great potential to contribute to the development of new diagnostic and therapeutic options to treat these disorders. Among a large number of existing neurotransmitter systems, the serotonin system dysfunction has been implicated in many psychiatric disorders and therapeutic efficacy of many drugs is also thought to be based on modulation of serotonin. Serotonin transporter gene polymorphism is one of the most extensively studied polymorphisms in psychiatric behavioral genetics. In this article, we review the status of evidence for association between the serotonin gene polymorphism and some common mental disorders like affective disorders, post-traumatic stress disorder, obsessive-compulsive disorder, suicide, autism, and other anxiety and personality disorders. Going beyond traditional association studies, gene-environment interaction, currently gaining momentum, is also discussed in the review. While the existing information of psychiatric genetics is inadequate for putting into practice genetic testing in the diagnostic work-up of the psychiatric patient, if consistent in future research attempts, such results can be of great help to improve the clinical care of a vast majority of patients suffering from such disorders.

Filicide-suicide, or murder of a child by a parent followed by suicide, has an unknown incidence in both the general and disabled population. As there is no national database, the authors examined known associated factors and newspaper reports to characterize filicide-suicide victims and perpetrators involving children with disabilities. A newspaper search was conducted using LexisNexis and NewsBank: Access World News databases through the University of California, Irvine Library's Web site. Age, gender of child and parent, method used, and diagnoses of parent and child were recorded. Twenty-two news articles were found describing a total of 26 disabled children as victims of filicide-suicide between 1982 and 2010. Eighty-one percent of children killed were male, and 54% were autistic. Thirty percent of perpetrators had a reported mental illness. Male children or children with autism may be at risk for filicide-suicide, but accurate record keeping is needed to determine the incidence and risk factors and aid in its prevention in the disabled population.

We previously demonstrated that patients with schizophrenia or bipolar disorder and their relatives are overrepresented in creative occupations. Here, we use a new dataset with a considerably larger sample of patients (n = 1,173,763) to survey other psychiatric diagnoses and to validate previous findings. The specific aims of this study were to i) investigate if creativity is associated with all psychiatric disorders or restricted to those with psychotic features, and ii) to specifically investigate authors in relationship to psychopathology. We conducted a nested case-control study using longitudinal Swedish total population registries, where the occurrence of creative occupations in patients and their non-diagnosed relatives was compared to that of matched population controls. Diagnoses included were schizophrenia, schizoaffective disorder, bipolar disorder, unipolar depression, anxiety disorders, alcohol abuse, drug abuse, autism, ADHD, anorexia nervosa, and completed suicide. Creative professions were defined as scientific and artistic occupations. Data were analyzed using conditional logistic regression. Except for bipolar disorder, individuals with overall creative professions were not more likely to suffer from investigated psychiatric disorders than controls. However, being an author was specifically associated with increased likelihood of schizophrenia, bipolar disorder, unipolar depression, anxiety disorders, substance abuse, and suicide. In addition, we found an association between creative professions and first-degree relatives of patients with schizophrenia, bipolar disorder, anorexia nervosa, and for siblings of patients with autism. We discuss the findings in relationship to some of the major components of creativity.
