The performance of patients with multiple sclerosis on selected psychological tests was examined to ascertain the usefulness of such examinations to diagnosis. Cognitive impairment was studied in relationship to disease-related factors, physician's identification of cerebral involvement, and psychological adjustment. The results indicate that half the(More)
Human (Homo sapiens) volunteers (N = 72) received saline, a low dose of oral scopolamine (0.6 mg), a high dose of oral scopolamine (1.2 mg), or a peripheral analogue (glycopyrrolate). They then underwent classical conditioning of the eyeblink response to a tone conditioned stimulus (CS) and a corneal airpuff unconditioned stimulus (UCS) in a delay(More)
OBJECTIVE To assess the safety, tolerability, and efficacy of interferon beta-1a (IFNbeta-1a) combined with methotrexate (MTX), i.v. methylprednisolone (IVMP), or both in patients with relapsing-remitting multiple sclerosis (RRMS) with continued disease activity on IFNbeta-1a monotherapy. METHODS Eligibility criteria included RRMS, Expanded Disability(More)
BACKGROUND AND PURPOSE Aptiganel (CNS 1102) is a selective, noncompetitive antagonist that acts on the ion channel associated with the N-methyl-D-aspartate (NMDA) receptor and is neuroprotective in experimental focal cerebral ischemia models at a plasma concentration of 10 ng/mL. In human volunteers, dose-limiting effects of aptiganel are blood pressure(More)
Most psychological and psychiatric studies of patients with multiple sclerosis (MS) have failed to take into account the varying demographic and disease-related factors that may be expected to play a role in patients' adjustment to this disease. We describe the psychological response of patients to MS as a function of age, sex, educational level, disease(More)
Intracranial hemorrhage occurred in two patients with cerebral arteritis. One patient with methamphetamine-induced necrotizing angitis had a spontaneous subarachnoid hemorrhage without an aneurysm. A second patient with ulcerative colitis developed an intracerebral hematoma. Carotid angiography demonstrated a diffuse arteritis in each patient. The risks of(More)

The first concern is that it may be possible to preserve a unified theory of concepts by distinguishing facts about concept individuation from facts about cognitive structures and processes. The second concern questions the sharpness of the distinction Machery draws(More)
implementation of health-based capitation risk adjustment in Minnesota public health care programs, and identifies key implementation issues. Capitation payments in these programs are risk adjusted using an historical, health plan risk score, based on concurrent risk assessment. Phased implementation of capitation risk adjustment for these programs began(More)
