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

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

Schizophrenia and other schizophrenia-spectrum disorders are neurodevelopmental disorders which may share genetic susceptibility factors and represent differential expressions of an underlying vulnerability. Schizophrenia may have its onset in childhood and can be reliably diagnosed. However, developmental factors modulate disease expression in children. Although the prevalence of schizophrenia in childhood is low, children who develop schizophrenia in adult life may show subtle and non-specific developmental abnormalities, consistent with the neurodevelopmental hypothesis.

Abstract:

AbstractPsychosis is thought to have a strong genetic component, but many efforts to discover the underlying putative schizophrenia genes have yielded disappointing results. In fact, no strong associations emerged in the first genome-wide association studies in psychiatry and weakly observed associations were not related to the candidate genes identified in previous studies. These partially successful findings may be explained by the fact that genetic research in psychiatry suffers from confounding issues related to phenotype definition, the considerable degree of phenotypic variability and di

It is widely assumed that psychopathic behaviour arises from unsatisfactory parenting, but upbringing difficulties are equally apparent in other psychiatric disorders. The poor response to psychological treatments is noteworthy and organic features, of a specific type, have been implicated. The most recent evidence strongly supports earlier findings of a genetic factor. Damage or malfunction of the left temporal lobe of the brain, or of the frontal area, are associated with violent psychopathic behaviour. Dysfunction in these same areas has also been found in schizophrenic patients and there i

Abstract:

T-type channels are low-voltage-activated calcium channels that contribute to a variety of cellular and physiological functions, including neuronal excitability, hormone and neurotransmitter release as well as developmental aspects. Several human conditions including epilepsy, autism spectrum disorders, schizophrenia, motor neuron disorders and aldosteronism have been traced to variations in genes encoding T-type channels. In this short review, we present the genetics of T-type channels with an emphasis on structure-function relationships and associated channelopathies.

Schizophrenia is a psychiatric illness in which disorders of thought content are a prominent feature.

This view has been changed due to increasing evidence that language per se is impaired in schizophrenia, especially its semantic, discursive, and pragmatic aspects. Schizoph

Background and aimRecent evidences of clinical overlap, familial co-aggregation, and shared genetic alterations support a neurodevelopmental deviation to represent a probable common vulnerability factor not only for the psychiatric disorders included in the meta-structure of neurodevelopmental disorders, but also for other major psychiatric disorders, including schizophrenia.The present paper reviews the literature to identify (1) positive and negative implications of the increasing enlargement of the group of neurodevelopmental disorders and (2) most useful clinical aspect for re-defining dia

Abstract:

Abstract Schizophrenia is a common psychiatric disorder, which is characterized by severe distortion of reality; disturbances in thoughts, feelings and behavior; according to DSM V is a disorder form deviations fundamentals and characteristics of thought and perception, and by the innapropriate or blunted affect. The influence of genetics is believed to have a role in psychiatric disorders, especially if the disorder has occurred in young adults or adolescents. The pathophysiology of schizophrenia is closely related to disorders of the biomolecular aspects of the central nervous system.

Abstract:

Schizophrenia (SZ) is a pervasive neurodevelopmental disorder that entails social and cognitive deficits, including marked language problems. Its complex multifactorial etiopathogenesis, including genetic and environmental factors, is still widely uncertain. SZ incidence has always been high and quite stable in human populations, across time and regardless of cultural implications, for unclear reasons. It has been hypothesized that SZ pathophysiology may involve the biological components that changed during the recent human evolutionary history, and led to our distinctive mode of cognition, wh

Abstract:

Although the incidence of the recurrent psychoses (bipolar affective illness and schizophrenia) in the two sexes is approximately equal, gender influences a number of aspects of major psychiatric disease: unipolar depressive illness is twice as common in females, onset of schizophrenia is earlier and outcome is worse in males, and pairs of psychotic first-degree relatives are more often than expected of the same sex. In addition, sex chromosomal aneuploidies (e.g. XXY and XXX) are more frequent in patients with psychosis. Some of these findings can be explained if there is a major locus of pre

Abstract:

Abstract Background Evidence suggests that neurocognitive dysfunction is a transdiagnostic feature of individuals across continuum between schizophrenia and bipolar disorder. However, there is a significant heterogeneity of neuropsychological and social cognitive abilities in schizophrenia, schizoaffective disorder and bipolar disorder. In recent years, several studies have investigated cognitive subgroups in schizophrenia-bipolar disorder continuum using data-driven methods and found that bipolar disorder includes several subgroups including a severely impaired and a neurocognitively intact c

Abstract:

The extreme male brain theory of autism posits that its male bias is mediated by exaggeration of male-biased sex differences in the expression of autism-associated traits found in typical populations. The theory is supported by extensive phenotypic evidence, but no genes have yet been described with properties that fit its predictions. The autophagy-associated gene AMBRA1 represents one of the top genome-wide “hits” in recent GWAS studies of schizophrenia, shows sex-differential expression, and has been linked with autism risk and traits in humans and mice, especially or exclusively among fema

Abstract BACKGROUND The effect of maternal age at conception on various aspects of offspring health is well documented and often discussed. We seldom hear about the paternal age effect on offspring health, although the link is now almost as solid as with maternal age. The causes behind this, however, are drastically different between males and females. CONTENT In this review article, we will first examine documented physiological changes linked to paternal age effect. We will start with all morphological aspects of the testis that have been shown to be altered with aging. We will then move on

Lately there is a growing interest in the negative symptoms in schizophrenia and their mechanisms of action, with special focus on the motivation process. The lack of motivation is increasingly recognized to be a very important impediment to positive management in schizophrenic pathology. In this mini-review, we described the current understanding of the nature and causes of the specific motivational deficits in schizophrenia in order to find better management strategies for this heterogeneous disorder.

Abstract Response to treatment with selective serotonin reuptake inhibitors (SSRIs) varies considerably between patients. The International SSRI Pharmacogenomics Consortium (ISPC) was formed with the primary goal of identifying genetic variation that may contribute to response to SSRI treatment of major depressive disorder. A genome-wide association study of 4-week treatment outcomes, measured using the 17-item Hamilton Rating Scale for Depression (HRSD-17), was performed using data from 865 subjects from seven sites. The primary outcomes were percent change in HRSD-17 score and response, defi
