Importance Patients with atrial fibrillation (AF) can have an ischemic stroke (IS) despite oral anticoagulant (OAC) treatment. Knowledge regarding the association between OAC discontinuation and the subsequent risk of recurrent IS in patients with AF is limited.Objectives To determine the risk of recurrent IS in patients with AF receiving OAC and to evaluate the association between OAC… Continue reading Recurrent Ischemic #Stroke in Patients With Atrial #Fibrillation While Receiving Oral Anticoagulants

Association of Terazosin, Doxazosin, or Alfuzosin Use and Risk of #Dementia With #Lewy Bodies in Men
Background and ObjectivesTerazosin, doxazosin, and alfuzosin (Tz/Dz/Az) are α-1 adrenergic receptor antagonists that also bind to and activate a key adenosine triphosphate (ATP)–producing enzyme in glycolysis. It is hypothesized that the increase in energy availability in the brain may slow or prevent neurodegeneration, potentially by reducing the accumulation of alpha-synuclein. Recent work has suggested a… Continue reading Association of Terazosin, Doxazosin, or Alfuzosin Use and Risk of #Dementia With #Lewy Bodies in Men
Changes in prevalence and incidence of #dementia and risk factors for dementia: an analysis from cohort studies
BackgroundSome cohort studies have reported a decline in dementia prevalence and incidence over time, although these findings have not been consistent across studies. We reviewed evidence on changes in dementia prevalence and incidence over time using published population-based cohort studies that had used consistent methods with each wave and aimed to quantify associated changes in… Continue reading Changes in prevalence and incidence of #dementia and risk factors for dementia: an analysis from cohort studies

Premenopausal bilateral #oophorectomy and #brain white matter brain integrity in later-life
INTRODUCTIONPremenopausal bilateral oophorectomy (PBO) is associated with later-life cognition, but the underlying brain changes remain unclear. We assessed the impact of PBO and PBO age on white matter integrity.METHODSFemale participants with regional diffusion tensor imaging (DTI) metrics of fractional anisotropy (FA) and mean diffusivity (MD) were included (22 with PBO < 40 years; 43 with PBO 40-45… Continue reading Premenopausal bilateral #oophorectomy and #brain white matter brain integrity in later-life
#Overweight in #Adolescence and Young Adulthood in Association With Adult #Cerebrovascular Disease: The NFBC1966 Study
BACKGROUND:Risk factors for cerebrovascular disease in adulthood are well known. However, research on individuals’ risk factors throughout their life span has been limited. This prospective cohort study aims to determine the effect of body mass index (BMI) and its changes in adolescence and young adulthood on early onset cerebrovascular disease.METHODS:This study includes 10 491 people (5185… Continue reading #Overweight in #Adolescence and Young Adulthood in Association With Adult #Cerebrovascular Disease: The NFBC1966 Study
#Glucagon-like peptide-1 receptor agonists and #stroke: A systematic review and meta-analysis of #cardiovascular outcome trials
Background:In patients surviving stroke, approximately 15% and 60% exhibit concurrent diabetes mellitus and overweight/obesity, respectively, necessitating heightened secondary prevention efforts. Despite glucagon-like peptide-1 receptor agonists (GLP-1 RAs) demonstrating improved outcomes for those with diabetes mellitus or obesity, their underutilization persists among eligible individuals. This systematic review and meta-analysis investigated the impact of GLP-1 RAs on… Continue reading #Glucagon-like peptide-1 receptor agonists and #stroke: A systematic review and meta-analysis of #cardiovascular outcome trials
#Cerebrovascular Effects of #Sildenafil in Small Vessel Disease: The OxHARP Trial
BACKGROUND:Vascular cognitive impairment due to cerebral small vessel disease is associated with cerebral pulsatility, white matter hypoperfusion, and reduced cerebrovascular reactivity (CVR), and is potentially improved by endothelium-targeted drugs such as cilostazol. Whether sildenafil, a phosphodiesterase-5 inhibitor, improves cerebrovascular dysfunction is unknown.METHODS:OxHARP trial (Oxford Haemodynamic Adaptation to Reduce Pulsatility) was a double-blind, randomized, placebo-controlled, 3-way… Continue reading #Cerebrovascular Effects of #Sildenafil in Small Vessel Disease: The OxHARP Trial
Prescribed Drug Use and #Aneurysmal Subarachnoid #Hemorrhage IncidenceA Drug-Wide Association Study
Background and ObjectivesCurrent benefits of invasive intracranial aneurysm treatment to prevent aneurysmal subarachnoid hemorrhage (aSAH) rarely outweigh treatment risks. Most intracranial aneurysms thus remain untreated. Commonly prescribed drugs reducing aSAH incidence may provide leads for drug repurposing. We performed a drug-wide association study (DWAS) to systematically investigate the association between commonly prescribed drugs and aSAH… Continue reading Prescribed Drug Use and #Aneurysmal Subarachnoid #Hemorrhage IncidenceA Drug-Wide Association Study
