Randomized Controlled Trial
The dementia antipsychotic withdrawal trial (DART-AD): long-term follow-up of a randomised placebo-controlled trial.
Data from 12-week placebo-controlled trials have led to mounting concerns about increased mortality in patients with Alzheimer's disease (AD) who are prescribed antipsychotics; however, there are no mortality data from long-term placebo-controlled trials. We aimed to assess whether continued treatment with antipsychotics in people with AD is associated with an increased risk of mortality. ⋯ UK Alzheimer's Research Trust.

Randomized Controlled Trial
Intravenous desmoteplase in patients with acute ischaemic stroke selected by MRI perfusion-diffusion weighted imaging or perfusion CT (DIAS-2): a prospective, randomised, double-blind, placebo-controlled study.
Previous studies have suggested that desmoteplase, a novel plasminogen activator, has clinical benefit when given 3-9 h after the onset of the symptoms of stroke in patients with presumptive tissue at risk that is identified by magnetic resonance perfusion imaging (PI) and diffusion-weighted imaging (DWI). ⋯ PAION Deutschland GmbH; Forest Laboratories.

Cerebral microbleeds (CMBs) are increasingly recognised neuroimaging findings in individuals with cerebrovascular disease and dementia, and in normal ageing. There has been substantial progress in the understanding of CMBs in recent years, particularly in the development of newer MRI methods for the detection of CMBs and the application of these techniques to population-based samples of elderly people. ⋯ Recent investigations with sensitive MRI techniques have indicated a high prevalence of CMBs in community-dwelling elderly people. We propose a procedural guide for identification of CMBs and suggest possible future approaches for elucidating the role of these common lesions as markers for, and contributors to, small-vessel brain disease.

Behçet's disease (BD) is a multisystem relapsing inflammatory disorder of unknown cause. In neuro-BD (NBD), the CNS can be involved in one or both of two ways: first, and most commonly, through the development of an immune-mediated meningoencephalitis, which predominantly involves the brainstem, but can also involve the basal ganglia, thalamus, cortex and white matter, spinal cord, or cranial nerves; and second, as a consequence of thrombosis within the dural venous sinuses. Headache is a common symptom in BD and does not necessarily indicate CNS involvement. ⋯ New treatment options have recently become available, which have led to an improvement in morbidity after meningoencephalitis. Most of the reported studies on NBD are retrospective. Collaborative prospective studies of the natural history of the disease, particularly the nature and treatment of progressive neurological disease, and evidence-based studies of treatment are needed.
