Quality Improvement Intervention for Reducing Acute Treatment Times in Ischemic Stroke: A Cluster Randomized Clinical Trial.

Importance: Efficient care processes are crucial to minimize treatment delays and improve outcome after endovascular thrombectomy (EVT) in patients with ischemic stroke. A potential means to improve care processes is performance feedback.

Objective: To evaluate the effect of performance feedback to hospitals on treatment times for EVT.

Cognition in (pre)symptomatic Dutch-type hereditary and sporadic cerebral amyloid angiopathy.

Introduction: Cerebral amyloid angiopathy (CAA) is a main cause of cognitive dysfunction in the elderly. We investigated specific cognitive profiles, cognitive function in the stage before intracerebral hemorrhage (ICH), and the association between magnetic resonance imaging (MRI) based cerebral small vessel disease (cSVD) burden in CAA because data on these topics are limited.

Methods: We included Dutch-type hereditary CAA (D-CAA) mutation carriers with and without ICH, patients with sporadic CAA (sCAA), and age-matched controls.

One Size Does Not Fit All: Micro-, Meso-, and Macrobleeds in Cerebral Amyloid Angiopathy.

Introduction: MRI rating criteria for small vessel disease markers include definitions for microbleeds and macrobleeds but do not account for small (<10 mm) hemorrhages with a cystic cavity and/or irregular shape. Such hemorrhages, however, are often present in patients with cerebral amyloid angiopathy (CAA). In this study, we aimed to investigate the frequency, diameter, and volume distribution of these hemorrhages (which we called mesobleeds) in patients with CAA.

Parental Influence on Intracerebral Hemorrhage Onset in Hereditary Dutch-Type Cerebral Amyloid Angiopathy.

Introduction: Dutch-type cerebral amyloid angiopathy (D-CAA) is an autosomal dominant hereditary form of CAA causing intracerebral hemorrhage (ICH) and cognitive decline. The age of onset of ICH in D-CAA mutation carriers is strikingly variable and ranges from late thirties up to 70 years. We investigated the presence of genetic anticipation and assessed the influence of parental age at onset and sex on age of ICH onset in offspring.
