Accurate clinical staging of dementia in older subjects has not previously been achieved despite the use of such methods as psychometric testing, behavioural rating, and various combinations of simpler psychometric and behavioural evaluations. The Clinical Dementia Rating (CRD), a global rating device, was developed for a prospective study of mild senile(More)
Clinical investigations of senile dementia of the Alzheimer type require establishment of explicit clinical diagnostic criteria before histological confirmation is possible. Criteria for selection of mildly impaired subjects with senile dementia of Alzheimer type, free of other major disease, are proposed. Problems of recruitment of this select population(More)
A third species of peccary, discovered in the Chaco of Paraguay, is added to the living members of family Tayassuidae. It is assigned to the genus Catagonus Ameghino, heretofore considered confined to the Pleistocene. The new peccary is conspecific with Catagonus wagneri (Rusconi), a species placed in the related extinct genus Platygonus LeConte when it was(More)
The frequency, differential diagnosis, and implications of depression occurring in the course of schizophrenia are considered in light of recently reported findings from a follow-up and family study of 500 psychiatric outpatients (the St. Louis 500 Study). Problems in diagnosis are illustrated in an interview of a schizophrenic patient with a history of(More)
OBJECTIVE The purpose of this study was to evaluate for APA a proposed strategy to diagnose somatization disorder for possible inclusion in DSM-IV. METHOD Five sites--Washington University, University of Kansas, University of Iowa, University of Arkansas, and Mount Sinai Medical Center in New York--participated in a collaborative field trial. Female(More)
We showed that schizophrenia was a discrete disorder by using a quantitative clinical scale that discriminated schizophrenics from other subjects in a prospective follow-up and family study of 500 psychiatric outpatients. Four symptoms tended to occur together as a stable syndrome throughout the six- to 12-year follow-up: persecutory delusions, delusions of(More)
In a six- to 12-year follow-up study of 500 psychiatric outpatients, death from natural causes occurred 11/2 times the expected rate, although the excess was not significant. Death from unnatural causes occurred 31/2 times the expected rate, a significant elevation. Suicide and homicide rates were particularly excessive. Unnatural mortality was excessive(More)
We describe the results of a follow-up study on patients with hysteria using the Minnesota Multiphasic Personality Inventory (MMPI) to evaluate the multiple complaints of these patients. MMPIs were obtained from 29 women with primary affective disorder and 37 women with Briquet's syndrome as part of a follow-up study of the St. Louis clinic 500. Patients(More)
The authors evaluated alternative criteria for somatization disorder in 277 female and 129 male psychiatric outpatients. In women, the diagnosis of somatization disorder based on DSM-III criteria was highly concordant with the diagnosis of Briquet's syndrome based on Guze's original criteria. There was familial aggregation for Briquet's syndrome in women(More)
Total or all-cause mortality data were determined from a prospective study of 500 randomly selected psychiatric outpatients during a mean follow-up period of seven years. With the use of age-, sex-, and race-adjusted methods, a mortality nearly twice that expected from reference population rates was observed. Mortality was excessive among younger, but not(More)
