- Diagnostic accuracy and linkage analysis: how useful are schizophrenia spectrum phenotypes?S V Faraone
Harvard Medical School Department of Psychiatry, Massachusetts Mental Health Center, Boston, USA
Am J Psychiatry 152:1286-90. 1995..However, most of these studies do not address a key measurement question: does the diagnostic accuracy of these spectrum classifications warrant their use in genetic linkage studies of schizophrenia?..
- Impact of genetic vulnerability and hypoxia on overall intelligence by age 7 in offspring at high risk for schizophrenia compared with affective psychosesJ M Goldstein
