Effect of immunotherapy with bapineuzumab on cerebrospinal fluid biomarker levels in patients with mild to moderate Alzheimer disease

Background: Given the slow and variable clinical course of Alzheimer disease, very large and extended clinical trials are needed to identify a beneficial clinical effect of disease-modifying treatments. Therefore, biomarkers are essential to prove that an anti-β-amyloid (Aβ) drug candidate affects both Aβ metabolism and plaque load as well as downstream pathogenic mechanisms.; Objective: To […]

Subgroup analysis of US and non-US patients in a global study of high-dose donepezil (23 mg) in moderate and severe Alzheimer’s disease

To better understand responses in the large number of US-based patients included in a global trial of donepezil 23 mg/d versus 10 mg/d for moderate-to-severe Alzheimer’s disease (AD), post hoc exploratory analyses were performed to assess the efficacy and safety in US and non-US (rest of the world [RoW]) patient subgroups. In both subgroups, donepezil […]

The NIH stroke scale can establish cognitive function after stroke

Background: Cognitive impairment is an important but underrecognised consequence of stroke. We investigated whether a subset of items from the NIH Stroke Scale (NIHSS) could yield valid information on cognitive status in a group of stroke patients.; Methods: 149 stroke patients from the Göteborg 70+ Stroke Study were investigated after 18 months.
