Amyloid-related imaging abnormalities in patients with Alzheimer's disease treated with bapineuzumab: a retrospective analysis.

Background: Amyloid-related imaging abnormalities (ARIA) have been reported in patients with Alzheimer's disease treated with bapineuzumab, a humanised monoclonal antibody against amyloid β. ARIA include MRI signal abnormalities suggestive of vasogenic oedema and sulcal effusions (ARIA-E) and microhaemorrhages and haemosiderin deposits (ARIA-H). Our aim was to investigate the incidence of ARIA during treatment with bapineuzumab, and evaluate associated risk factors.

Lethality of Alzheimer disease and its impact on nursing home placement.

This analysis evaluates the progression of Alzheimer disease (AD) severity and compares the life expectancy and nursing home placement rates for AD patients with the same measures in the general population. Data from the Consortium to Establish a Registry for Alzheimer Disease were analyzed to estimate expected survival, time spent in each Clinical Dementia Rating stage, and nursing home admission rate for a hypothetical cohort of patients aged 70 years with new-onset AD. Corresponding estimates for the US general population were calculated from the 2004 National Nursing Home Survey and the 2003 life table estimates from the US Census Bureau.
