Introduction: Intracranial atherosclerotic disease (ICAD) of the large cerebral arteries, a leading cause of stroke worldwide, is increasingly implicated in cognitive impairment and neurodegeneration among the general population; however, the underlying pathophysiologic mechanisms in this relationship remain unknown.
Methods: In this narrative review, we aim to provide an overview of the epidemiology and pathophysiology of ICAD, the evidence that relates ICAD to neurodegeneration, putative mechanisms, and future research directions. We synthesized available evidence on PubMed up to August 2024.

Purpose Of Review: The overwhelming majority of stroke burden can be prevented through the pillars of lifestyle medicine: diet, exercise, sleep, substance abuse, stress management, and healthy relationships. Among these, diet confers the greatest attributable risk.
Recent Findings: Despite abundant data and integration of lifestyle medicine within major stroke prevention guidelines, several barriers to effective implementation remain.
Although men are at higher risk of stroke throughout most of their lifespan, the incidence of stroke in women climbs with age, increasing after menopause and rising sharply after 85 years. This, combined with women's longer life expectancy, results in most of the stroke deaths occurring in women. In addition to accounting for a larger proportion of strokes, women may also suffer a survival disadvantage, which may be due to several factors.

The association of dietary patterns with Alzheimer disease (AD) pathology has been suggested using neuroimaging biomarkers. This study examined the association of Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) and Mediterranean dietary patterns with β-amyloid load, phosphorylated tau tangles, and global AD pathology in postmortem brain tissue of older adults.

Objective: To quantify the role of lifestyle pre-stroke, post-stroke, and changes in lifestyle before and after stroke with cognitive decline in community-dwelling stroke survivors.
Methods: Utilizing data from the Chicago Health and Aging Project, a population-based cohort study, we studied 1,078 individuals with stroke (662 incident and 416 prevalent) who underwent cognitive testing during the study period.
The present study examines the association of diet with depressive symptoms among stroke survivors from a community cohort of older adults. Depression is common after stroke. A healthy diet has previously been associated with fewer depressive symptoms in older individuals, but it is unknown if this effect is also seen in stroke survivors.

Objective: This study investigated if pelargonidin or berry intake is associated with Alzheimer's disease (AD) neuropathology in human brains.
Methods: The study was conducted among 575 deceased participants (age at death = 91.
We sought to analyze the effect of COVID-19 on telestroke requests and to characterize patients remotely evaluated for acute ischemic stroke (AIS) during this time. This study is a retrospective database review of all telestroke requests at one academic vascular neurology center telestroke network with seven remote sites in the USA between March 15 and April 30, 2020. Data were compared with historical cohort spanning same time frame in 2019 using parametric or nonparametric methods as appropriate.
View Article and Find Full Text PDFBackground: Acute ischemic stroke (AIS) is rare in children, and diagnosis is often delayed. Neurological involvement may occur in multisystem inflammatory syndrome in children (MIS-C), but very few cases of AIS in patients with MIS-C have been reported.
Patient Descriptions: We two patients with AIS presenting with large vessel occlusive disease in previously healthy adolescents recently exposed to SARS-CoV-2 infection.
Background: MIND diet, a hybrid of the Mediterranean diet and the Dietary Approaches to Stop Hypertension diet, is associated with a slower cognitive decline and lower risk of Alzheimer's disease (AD) dementia in older adults.
Objective: We aim to examine whether the association of the MIND diet with cognition is independent of common brain pathologies.
Methods: Utilizing data from the Rush Memory and Aging Project (MAP), a longitudinal clinical-pathologic study, we studied 569 decedents with valid dietary data, cognitive testing proximate to death, and complete autopsy data at the time of these analyses.
Background: Depression is common in older adults and more prevalent in those with cognitive impairment, vascular risk factors, or stroke. Nonpharmacologic strategies to reduce depression, such as diet, may be effective; however, few studies have investigated the relation.
Methods: A total of 709 participants (23.

Introduction: Despite the increasing national adoption of automated computed tomography perfusion (CTP) to select thrombectomy patients 6 hours after last known well, reliability issues have been anecdotally reported. Unreliable diagnostic tests add time and confusion to a process that requires efficiency. Our study aims to critically assess an automated CTP program in a contemporary cohort of patients presenting with large vessel occlusion (LVO) in the extended time window by evaluating the rate of unreliable automated CTP maps and whether this influences clinical outcomes.

Objective: To determine characteristics associated with early chemoprophylaxis (CP) after ICH in the Get With The Guidelines-Stroke registry.
Background: We sought to assess the effects of participation in a tele-stroke program on timeliness of intravenous tissue plasminogen activator (IVtPA) administration.
Methods: Among 259 consecutive acute ischemic stroke patients treated with IVtPA through the Rush tele-stroke program, we compared two cohorts: Period 1 (July 2011 to June 2013) and Period 2 (July 2013 to July 2014). We collected data on demographics, National Institutes of Health Stroke Scale (NIHSS), and times of last known normal (LKN), initiation of tele-stroke consult, and IVtPA administration.
Intravenous thrombolysis is considered to be standard of care for acute ischemic stroke patients arriving within 3-4.5 h of stroke symptom onset. Recently, endovascular therapies have been proposed to extend and enhance stroke outcomes by targeting large vessel occlusions.
