Accuracy of biomarker testing for neuropathologically defined Alzheimer disease in older adults with dementia
This study is a systematic review of biomarker and test accuracy for identification of Alzheimer Disease (AD) in older adults. Studies with low or medium risk of bias were analyzed, and two reviewers rated risk of bias. Fifteen brain imaging studies and 9 cerebrospinal fluid (CSF) studies met analysis criteria and were included. The meta-analysis found that in methodologically heterogeneous studies of uncertain applicability to typical clinical settings, the biomarkers amyloid PET, 18F-FDG proton emission tomography (PET), and magnetic resonance imaging (MRI) were highly sensitive for neuropathologic AD. Single studies suggested that adding amyloid PET, 18F-FDG PET, and CSF test combinations may add accuracy to clinical evaluation.

Benefits and harms of prescription drugs and supplements for treatment of clinical Alzheimer-type dementia
This is a systematic review and meta-analysis of the benefits and harms of prescription drugs and supplements for treatment of clinical Alzheimer-type dementia (CATD). Studies with low or medium risk of bias (ROB) were analyzed and rated. The analysis concluded there was a slight reduction in short-term cognitive decline with cholinesterase inhibitors and memantime, and cholinesterase inhibitors slightly reduced reported functional decline. There was mostly insufficient evidence on drug treatment of behavioral and psychological symptoms of dementia and on supplements for all outcomes.

Brief cognitive tests for distinguishing clinical Alzheimer-type dementia from mild cognitive impairment or normal cognition in older adults with suspected cognitive impairment.
Researchers summarized evidence on accuracy and harms of brief cognitive tests for clinical Alzheimer-type dementia (CATD) in older adults with suspected cognitive impairment. They encountered the following limitations: small studies, few test metrics being evaluated by multiple studies, and few studies directly comparing different tests, scores, cut points, or test combinations. They concluded that many brief, single cognitive tests accurately distinguish CATD from normal cognition in older adults but are less accurate in distinguishing mild CATD from normal cognition or CATD from mild cognitive impairment.

Improving Recovery and Outcomes Every Day after the ICU (IMPROVE): study protocol for a randomized controlled trial.
The Improving Recovery and Outcomes Every Day after the ICU (IMPROVE) trial is an ongoing clinical trial which evaluates the efficacy of a combined physical exercise and cognitive training on cognitive function among ICU survivors 50 years and older who experienced delirium during an ICU stay. This article describes the study protocol for IMPROVE.

Intermediate- and long-term cognitive outcomes after cardiovascular procedures in older adults: a systematic review.
This study summarized evidence about cognitive outcomes in adults aged 65 years or older at least 3 months after coronary or carotid revascularization, cardiac valve procedures, or ablation for atrial fibrillation. It concluded that intermediate- and long-term cognitive impairment in older adults attributable to the studied cardiovascular procedures may be uncommon.

Longitudinal patient-oriented outcomes in neuropathy: importance of early detection and falls.
This study evaluated longitudinal patient-oriented outcomes in peripheral neuropathy over a 14-year time period including time before and after diagnosis. It concluded that, in older persons, differences in falls, pain, and self-rated health can be detected 3–5 years prior to peripheral neuropathy diagnosis, but only falls deteriorate more rapidly over time in neuropathy cases compared to controls.
