Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study will ask relatives of deceased individuals to donate the brains of their deceased relatives to allow further study of neurological and psychiatric disorders. We do not accept prospective donations.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Dissected brain tissue from selected brain regions, including but not limited to the dorsolateral prefrontal cortex and hippocampal formation, will be assembled from large cohorts of normal controls and schizophrenic subjects. The expression of mRNA and protein for selected molecules, chosen on the basis of their genetic association with schizophrenia, will be measured with a variety of assays including but not limited to qPCR and Western blots.
Outcome measures are the statistical comparison within normal controls of mRNA and/or protein levels in groups segmented by genotype. Similar comparisons will be made between schizophrenic cohorts and normal controls, in a diagnosis by genotype analysis with an ANOVA, or when appropriate an ANCOVA (controlling for variables such as age, race, gender, and postmortem interval).
