BACKGROUND Little is known about the effect of sex on age-related changes in brain structure. METHODS Quantitative magnetic resonance imaging of the brain was performed in 330 elderly (age range, 66-96 years) volunteers living independently in the community, all of whom were participants in the Cardiovascular Health Study. Blinded measurements of global(More)
We measured initial seizure threshold by means of a structured stimulus dosage titration procedure in a clinical sample of 111 depressed patients undergoing brief-pulse, constant-current electroconvulsive therapy (ECT). Initial seizure threshold was approximately 60 millicoumbs (mc) (10 Joules) on average, but varied widely (6-fold) across patients. Initial(More)
OBJECTIVE To examine the relations between education and age-related changes in brain structure in a nonclinical sample of elderly adults. BACKGROUND Education may protect against cognitive decline in late life--an observation that has led to the "reserve" hypothesis of brain aging. Little is known, however, about the effect of education on age-related(More)
To measure the anticonvulsant effects of a course of electroconvulsive therapy (ECT), we used a flexible stimulus dosage titration procedure to estimate seizure threshold at the first and sixth ECT treatments in 62 patients with depression who were undergoing a course of brief pulse, constant current ECT given at moderately suprathreshold stimulus(More)
The relations between age-related changes in brain structure and neuropsychological test performance in 320 elderly nonclinical volunteers (ages 66-90) were examined by using quantitative MRI data and measures of attention, information processing speed, language, memory, and visuospatial ability. Final path analyses revealed significant brain-behavior(More)
We previously reported a trend toward a higher mean nocturnal serum melatonin (MEL) concentration, based on 30-min blood sampling over 24 h, in 23 female definite endogenous depressive compared to 23 matched normal female control subjects, and no significant difference in 15 male depressives compared to their controls (Rubin et al., 1992). In both groups of(More)
Children with myelomeningocele (MM) are very short and respond to treatment with recombinant human growth hormone (RHGH) with an acceleration in growth. Following primary closure of the MM, a tethered spinal cord may produce neurologic and orthopedic deformities. We compared the short-term growth rate and length standard deviation score (L-SDS) for stature(More)
Far-field somatosensory and auditory evoked potential (EP) interpeak latencies were measured in normal controls, epileptics not receiving medications, and epileptics receiving phenytoin, phenobarbital, or both. Phenytoin, but no phenobarbital, was associated with a prolongation of EP interpeak latencies at serum level concentrations over 20 micrograms/ml.(More)
OBJECTIVES To assess the effects of intrathecal baclofen (ITB) therapy for the treatment of poststroke spastic hemiparesis on quality of life, functional independence, and upper, lower extremity (UE, LE) motor functions. MATERIALS AND METHODS Prospective observational study of adult men and women with a minimum 6-month stroke-related spastic hemiparesis(More)
