Genetics of Schizophrenia
Genetic etiology in schizophrenia is widely accepted. However, many chromosomal sites were shown to characterize the families of patients with schizophrenia. This is probably due to the high genetic heterogenity of this illness. Thus, it is important to investigate the genetic factor in relatively genetically homogenous populations. Many studies have indicate that Ashkenazy Jews show relative gentic homogenity. Indeed, the genes responsible for most Mendelian disorders of Jewish peoples have been identified. The study will apply genome-wide mutation screening methods to identify candidate allells in subjects of Ashkenazi Jewish ancestry with multiplex schizophrenia.

A chronic form of schizophrenia characterized primarily by the presence of persecutory or grandiose delusions, often associated with hallucination.
A type of schizophrenia characterized by abnormality of motor behavior which may involve particular forms of stupor, rigidity, excitement or inappropriate posture.
An obsolete concept, historically used for childhood mental disorders thought to be a form of schizophrenia.
A type of schizophrenia characterized by frequent incoherence; marked loosening of associations, or grossly disorganized behavior and flat or grossly inappropriate affect that does not meet the criteria for the catatonic type; associated features include extreme social withdrawal, grimacing, mannerisms, mirror gazing, inappropriate giggling, and other odd behavior.

A benzocycloheptapyridoisoquinolinol that has been used as an antipsychotic, especially in schizophrenia.
This study will create a DNA collection with blood samples from families with at least two siblings who have schizophrenia symptoms. This collection will help scientists identify genes tha...
Schizophrenia has long been known to be an illness with significant evidence for a genetic predisposition. The purpose of this study is to determine the genetic abnormalities that cause c...
The proposed study would evaluate the benefits of riluzole add-on treatment to patients with schizophrenia who are already receiving medications, but still experience symptoms. Neuroprotec...
The objective of this study is to evaluate the effectiveness of a marketed drug in the treatment of schizophrenia, as an add-on therapy to antipsychotics over a 12-week period. Subjects wi...
This study will evaluate the effectiveness of switching medications in decreasing schizophrenia symptoms in individuals who are currently taking an antipsychotic medication for the treatme...
Empirical evidence continues to suggest a biologically distinct violent subtype of schizophrenia. The present study examined whether murderers with schizophrenia would demonstrate resting EEG deficits...
Background: In the 20th century, catatonia was usually deemed a subtype of schizophrenia. Recently, the nature and classification of catatonia are being reconsidered. This study is the first to descri...
How will we view schizophrenia in 2030? Schizophrenia today is a chronic, frequently disabling mental disorder that affects about one per cent of the world's population. After a century of studying sc...
The evidence regarding the association between schizophrenia and the fractions of bilirubin is mixed. In a retrospective case-control design we examined the association between total bilirubin, conjug...
The gene encoding d-amino acid oxidase (DAO), which acts as a receptor for the schizophrenia-associated neurotransmitter, N-methyl-D-aspartate (NMDA), is regarded as a potential candidate gene for sch...
