Abstract:

AbstractThe relatively high comorbidity of type 2 diabetes and schizophrenia may suggest a shared biological susceptibility to these twoconditions. Family studies have demonstrated an increased risk of diabetes in unaffected relatives of patients with schizophrenia, consistent with a heritable susceptibility trait. Linkage analyses have identified several loci that are associated with schizophrenia and some of these, notably those on chromosomes 2p22.1-p13.2 and 6g21-824.1 have also been observed in linkage studies in type 2 diabetes. In addition, the dopamine D5 receptor on chromosome 5 and t

AbstractThe concept of deficit schizophrenia is regarded as one of the most promising attempts to reduce heterogeneity within schizophrenia. This paper summarizes the clinical, neurocognitive, brain imaging and electrophysiological correlates of this subtype of schizophrenia. Attempts to identify genetic and non-genetic risk factors are reviewed. Methodological limitations of studies supporting the efficacy of atypical antipsychotics in the treatment of the syndrome are highlighted.

Abstract:

ABSTRACT Epidemiological evidence suggests that etiology of schizophrenia may involve both the influence of genetic factors specific for the individual and the impact of the environment. It is quite likely that a crucial role in the disease development is played by molecular mechanisms mediating the interaction between genes and environment. Modern research have shown that epigenetic mechanisms or chemical modifications of deoxyribonucleic acids (DNA) and histone proteins remain unstable throughout life and can be changed by environmental factors. Thus the epigenetic mechanisms outline an attr

Abstract:

A number of factors have been proposed as being linked to schizophrenia: genetic, psychological, endocrinological, metabolic, environmental, virological, and auto-immunological factors, as well as neurotransmitter systems and structural disorders of the brain. All may act as predisposing, triggering, or functionally modulating factors in what is probably a condition composed of several types of disorder with varying aetiology. Neuroanatomical and neuromorphological data have revealed ventricular enlargement and diminished frontal and temporal lobe volume in some patients. These changes are con

Abstract:

Complex diseases, unlike Mendialian diseases, are often characterized by genetic heterogeneity and multifactorial inheritance, involving defects in genes from the same or multiple alternative pathways. Many congenital diseases and psychiatric disorders are complex diseases, and incur heavy health care burden on the society. With the advancement in high-throughput genotyping technologies and the availability of the human single nucleotide polymorphism (SNP) catalogue, genome-wide association study (GWAS) has been widely used to investigate the genetic component of complex diseases.

Abstract:

Although heritability estimates of schizophrenia are high, studies attempting to identify specific genes for schizophrenia have been only modestly successful. Strategies to improve the power of genetic studies include the creation of homogeneous subtypes of schizophrenia based on symptom presentation, and the identification of behavioural abnormalities that reflect the presence of genes for schizophrenia ("behavioural markers of risk") even in the absence of the full clinical disorder. Oculomotor abnormalities are one of the most well-documented markers of risk. It is not known whether

The majority of molecular genetic work done has involved Caucasian populations, with studies in these and Asian populations showing 2-32% of sufferers to have chromosomal aberrations. So far the discovery of a specific susceptibility mechanism or gene still eludes us, but the use of endophenotypes is advocated as a useful tool in this search.

Abstract:

A neurodevelopmental model of schizophrenia postulates that some of the key aspects of brain development that normally occur both pre- and post-natally are not occurring correctly, either in time or space. Complex neural circuitry needs to form and be modulated by experience. Classically, proliferation, migration, arborization and myelination occur prenatally. Elaboration and refining of dendritic trees and synapses as well as myelination of the nervous system continues through the first two-decade of life. There are opportunities for genetic and environmental abnormalities and variation to profoundly influence the trajectories of all of these critical functional processes.

Abstract:

Schizophrenia spectrum disorders are characterized by the presence of delusions, hallucination, disorganized thinking, motor abnormalities, and/or negative symptoms. Behaviourally, schizophrenia patients have profound difficulties in regulating approach and avoidance, causing social withdrawal or aggressive behaviour. Evolutionary hypotheses of schizophrenia abound, but none covers all phenotypic aspects of the syndrome(s). Genetic risk for schizophrenia is partly conferred by genes that have undergone positive selection, whereby the reproductive advantage compensating for the reduced fecundity is as yet unknown. Environmental risk factors for schizophrenia comprise poverty, migration, and urbanicity, which has given rise to the hypothesis that individuals with schizophrenia are particularly sensitive to the exposure of strangers. In a more general vein, many signs and symptoms associated with schizophrenia can be interpreted from an evolutionary point of view. They pertain to diverse aspects of social life, including cooperation and trust (paranoia), mating (delusional jealousy, erotomania), and social rank (catatonic stupor, mutism).

Abstract:

Schizophrenia is a devastating illness that usually affects many aspects of a person’s life. The symptoms may be divided into two groups. ‘Positive’ symptoms include a variety of psychotic symptoms such as delusions and hallucinations. Although severe, they are less handicapping than negative symptoms such as avolition or anhedonia. Positive symptoms involve the presence of things that should be absent, while negative symptoms involve the absence of things that should be present. Dimensional approaches for classifying symptoms have also become popular in current nosology, proposing three dimensions: positive, negative, and disorganized. The course of the illness evolves over time; a prodrome is often present, followed by illness onset and a variable outcome. Good outcome predictors include good premorbid adjustment, high intelligence quotient, and good social relationships. The pathophysiology of the illness includes genetic, neuropathological, and neurodevelopmental components. A possible association with creativity may suggest reasons why the illness has persisted over many centuries.

Abstract:

Epidemiological approaches to understanding the frequency, distribution, and determinants of psychotic disorders, such as schizophrenia, have played a vital role in delineating the aetiology and course of these conditions for almost a century. Despite several milestones, reviewed in this chapter, many methodological and clinical aspects of these disorders continue to provide challenges to studying the epidemiology of psychotic disorders, including issues of case definition, case ascertainment, and study design. After summarizing these challenges, we review the current neuropsychiatric epidemiologic knowledge of the incidence, prevalence, and aetiology of psychotic disorders. Here, we also provide a contemporary overview of the role that genetic, neurodevelopmental, demographic and environmental risk factors, including inflammation, traumatic life events, substance abuse, urban living, and minority status have on risk, course, and outcome of psychotic disorder. We conclude with future directions required to elucidate the interplay of these factors in contributing to the global burden of psychotic disorders.

Abstract:

A goal for the treatment of psychotic disorders, such as schizophrenia and bipolar disorder, is to correct the function of neural circuits that have been implicated in the range of symptoms from altered sensory perception to impaired cognition. However, this goal is complicated by the absence of an obvious lesion, genetic mutation, or even a clear disease process. The brains of people with psychotic illness just appear to work differently. Dopamine receptor blocking strategies repress the more florid symptoms of psychosis, but appear to do little to influence the underlying dysfunction of brain circuits, and they do not improve the patient’s cognition. Voltage-gated ion channels (VGICs) are proteins that define neurons: they are required for all aspects of neural processing and signaling. Could modulation of these highly dynamic proteins be useful in the treatment of psychosis? This chapter reviews examples of VGICs that have been linked to psychosis and that may take us toward the goal of better treatments for these devastating disorders. This chapter covers specific examples of chloride, calcium, potassium and VGIC channel pathology associated with psychosis.

Abstract:

This chapter focuses on two disorders in the schizophrenia ‘spectrum’: schizoaffective disorder and schizotypal personality disorder. The emphasis includes the clinical features, classification, diagnosis, epidemiology, aetiology, course, prognosis, and possibilities for prevention for each disorder. Some aspects will be underscored to reflect controversial issues, such as the heterogeneity apparent in each condition. Such issues relate to the accurate classification of the disorders, which is important for at least two reasons. First, it is essential to develop reliable and valid diagnostic criteria in order to study the aetiology of the disorders and then utilize that knowledge to develop rational and testable intervention strategies. Heterogeneity adds variance to the process that reduces both the reliability of diagnosis and also the statistical power of experimental designs to detect intervention/treatment effects. Second, the development of newer generations of psychopharmacological treatments holds the promise of matching more appropriate and efficacious medications with specific syndromes or types of symptoms. This trend underscores the importance of differential diagnosis in determining what treatment a patient will receive. Heterogeneity within a diagnostic category complicates achievement of this goal. Another area to be emphasized involves the goal of early interventions, in addition to palliative treatments for these disorders. In contrast, other areas such as the genetic aetiology of schizoaffective disorder and schizotypal personality disorder, and treatments for schizoaffective disorder, will receive less emphasis here, to avoid redundancies with other chapters in this volume. Each disorder will be considered separately, starting with a review of schizoaffective disorder, the more severe of the two spectrum conditions.

Abstract:

This chapter examines the basic pharmacology of psychotropic drugs. Besides knowing what drugs do to certain chemicals or proteins in the brain, it is important to know where drugs affect those chemicals or proteins. There is some basic knowledge about neuroanatomy that is relevant to the clinical practice of psychopharmacology. It is accepted that neurobiology is an important factor in the etiology and pathophysiology of major psychiatric conditions—like schizophrenia and manic-depressive disease, as well as in other psychiatric clinical pictures. The general summary usually provided is that neurobiology represents a diathesis to psychiatric conditions, which is supplemented by environmental stress to produce observed clinical pictures. This mixture of genetics and environment is oversimplified in the minds of most mental health professionals. In fact, the mix depends on the illness. The biochemical neuroanatomy of the monoamines, glutamate, and GABA in the brain are discussed. Pharmacokinetic aspects of psychopharmacology are reviewed, including hepatic metabolism, drug half-lives, dosing, and tolerance and sensitization.
