The neuropathology could also be a trait marker of vulnerability to selleck kinase inhibitor schizophrenia rather than related directly to symptoms themselves, as is the case for many of the MRI findings. The ability to answer these challenging questions will require a sustained and sophisticated approach to postmortem schizophrenia research over the next, decade.

An understanding of how schizophrenia develops is essential for developing

treatment strategies aimed at preventing the disorder. Before such strategies can be formulated, it will be necessary to identify the liability for schizophrenia. That is, what is the vulnerability Inhibitors,research,lifescience,medical to schizophrenia before the onset of psychosis? Recently, Inhibitors,research,lifescience,medical we addressed this issue in a companion paper to this one by describing “schizotaxia,” a clinically meaningful condition that may reflect liability for schizophrenia.1 In this paper, we describe the model of schizotaxia further by focusing on its etiology and development, and on its clinical,

neuropsychological, and biological bases. We begin with a brief review of the concept, followed by a consideration of its genetic and environmental etiologies, and its likely neurodevelopmental course. Associated clinical and neuropsychological components of schizotaxia are then reviewed, Inhibitors,research,lifescience,medical followed by an update on our attempts to use these symptoms to develop treatment protocols. Finally, prospects for future research center on the need to incorporate biological function into the conceptualization

Inhibitors,research,lifescience,medical and treatment of the syndrome. Schizotaxia Paul Meehl introduced the term “schizotaxia” in 1962 to describe the genetic predisposition to schizophrenia,2 which he Inhibitors,research,lifescience,medical believed resulted in a subtle, neural integrative defect. He proposed that schizotaxic individuals would eventually develop either schizotypy or schizophrenia, depending on environmental circumstances. Although schizotypy (in the form of schizotypal personality disorder) eventually entered the psychiatric nomenclature, schizotaxia did not. Instead, it became associated with the premorbid, neurobiological substrate of schizophrenia, but not with a clinically found meaningful syndrome. Now, after more than three decades of research, the accumulated evidence suggests that schizotaxia is, in fact, a clinically consequential condition and a risk factor or marker for subsequent psychosis. As such, it encompasses aspects of both vulnerability and disease. In our reformulation of the concept, differences emerged from Mcehl’s original view. While our use of the term remains consistent with Meehl’s view of it as the underlying defect among people genetically predisposed to schizophrenia, it differs from his theory in at least four significant ways.
