A prospective sample of 69 healthy adults, age range 18-80 years, was studied with magnetic resonance imaging scans (T2 weighted, 5 mm thick) of the entire cranium. Volumes were obtained by a segmentation algorithm that uses proton density and T2 pixel values to correct field inhomogeneities ("shading"). Average (+/- SD) brain volume, excluding cerebellum,(More)
It is anticipated that the number of people older than 65 years with psychiatric disorders in the United States will increase from about 4 million in 1970 to15 million in 2030. The current health care system serves mentally ill older adults poorly and is unprepared to meet the upcoming crisis in geriatric mental health. We recommend the formulation of a 15-(More)
OBJECTIVES To review progress made during the past decade in late-life mood disorders and to identify areas of unmet need in health care delivery and research. PARTICIPANTS The Consensus Development Panel consisted of experts in late-life mood disorders, geriatrics, primary care, mental health and aging policy research, and advocacy. EVIDENCE (1)(More)
In November 1999, a working group of the American Association for Geriatric Psychiatry (AAGP) convened to consider strategic recommendations for developing geriatric mental health services research as a scientific discipline. The resulting consensus statement summarizes the principles guiding mental health services research on late-life mental disorders,(More)
The purpose of our study was to examine the neuroanatomical correlates of late-onset minor and major depression and to compare them with similar measures obtained from nondepressed controls. Our study groups were comprised of 18 patients with late-onset minor depression, 35 patients diagnosed with late-onset major depression, and 30 nondepressed controls.(More)
OBJECTIVE To examine the neuroanatomical correlates of late-life minor depression using magnetic resonance imaging. DESIGN Cross-sectional quantitative magnetic resonance imaging study of elderly patients with minor depression and age-matched controls. SETTING Patients and controls were recruited from the community through advertisements to the Section(More)
The purpose of the study was to examine global and regional volumetric asymmetries in patients with late-onset mood disorders and non-depressed control subjects. Our sample comprised 34 patients with late-onset major depression, 18 patients diagnosed with late-onset minor depression and 30 control subjects. All subjects were scanned using a 1.5 Tesla GE(More)
The authors examined the individual and relative roles of atrophy, comorbid medical illness, and cerebrovascular risk factors in the pathogenesis of late-life major depressive disorder (MDD). They used magnetic resonance imaging techniques to study 28 subjects with late-life MDD, 29 healthy control subjects, and 34 subjects with probable dementia of the(More)
For 43 patients with probable Alzheimer's disease who were screened for psychiatric disorders, the interrater reliability of the Global Deterioration Scale, BPRS, and Hamilton Rating Scale for Depression was high (intraclass correlation, 0.82-0.998). As expected, the prevalence of psychiatric symptoms in this sample was low. The score on the Zung(More)
