Background And Purpose: Although a lower incidence of stroke has been observed in the Mediterranean area compared to other European countries, this is based on only a few studies. We sought to determine the incidence and 28-day case-fatality of stroke through a population-based stroke register in a rural area in Southern Italy, characterized by a stroke unit in the referral hospital.
Methods: We established a multisource prospective population-based register in a well defined geographic area of 38 735 inhabitants in Puglia, Southern Italy. We identified all subjects in the study area with a first-ever stroke between January 1, 2001 and December 31, 2002.
Results: We identified 127 first-ever strokes (77 males, 50 females) during the two-year study period. Hospitalization was 95%: 92 cases (72.4%) were cerebral infarction, 24 (18.9%) intracerebral hemorrhage, 3 (2.4%) subarachnoid hemorrhage, and 8 (6.3%) were unclassifiable strokes. The overall crude annual incidence was 1.6 per 1000 (95%CI: 1.4 to 1.9), 2.0 for males (95% CI:1.6 to 2.5), and 1.3 for females (95% CI:0.9 to 1.6). The incidence rates standardized to the 2001 European and world populations were respectively 1.5 (2.0 for males and 1.3 for females) and 0.8 (0.9 for males and 0.6 for females). Incidence rates progressively increased with age in both sexes, reaching their peak at 85 years or more (21.4/1000 overall, 35.0 for men and 13.4 for women). The 28-day case-fatality was 18.1%.
Conclusions: Our study supports previous findings of lower incidence of stroke in the Mediterranean area, whereas the case-fatality in our study was lower than in previous studies from Italy. Further studies are needed to determine the role of prompt referral and stroke units on prognosis in population-based setting.

Background: Current guidelines recommend transcatheter aortic valve implantation (TAVI) for patients with aortic stenosis and porcelain aorta (PA). Neurological outcomes of patients with PA undergoing TAVI with modern valves require clarification as most trials examined balloon-expandable valves (BEV) and self-expandable valves in intermediate or high-risk patients, but not specifically in patients with PA. Our aim was to compare outcomes, including stroke and mortality, in well-matched patients with and without PA who received BEV during transfemoral TAVI procedures.

Background: Lifestyle affects the risk of cardiovascular events such as myocardial infarction and stroke. Several lifestyle factors, such as physical activity (PA), are modifiable, and in this study, we examined the association between leisure-time PA habits and the risk of a first-ever stroke.
Methods: This prospective study included residents in Västerbotten, Sweden, who participated in the Västerbotten Intervention Programme at 40, 50, and 60 years of age.
Associations of Traumatic Brain Injury and Mild Behavioral Impairment With Cognitive Function and Dementia.

Objective: Traumatic Brain Injury (TBI) may contribute additional complexity to the clinical picture of mild behavioral impairment (MBI). MBI, a behavioral analog to mild cognitive impairment (MCI), is comprised of five neuropsychiatric domains: decreased motivation, affective dysregulation, impulse dyscontrol, social inappropriateness, and abnormal perception/thought content. We investigated (1) if cross-sectional associations of cognitive status with MBI symptoms differ by TBI status and (2) if prospective associations of MBI domain positivity with incident dementia risk differ by TBI status.

To study the risk of incident dementia after a non-traumatic intracranial hemorrhage in a diverse US population, and evaluate if this risk is different for the subtypes of intracranial hemorrhage. We performed a retrospective cohort study using both inpatient and outpatient claims data on Medicare beneficiaries between January 1, 2008 and December 31, 2018. The exposure was a new diagnosis of non-traumatic intracranial hemorrhage, defined as a composite of intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and subdural hemorrhage (SDH).

We aimed to investigate whether the addition of AF polygenic risk scores (PRS) to existing clinical risk predictors could improve prediction of AF after stroke. Patients diagnosed with ischemic stroke at Massachusetts General Hospital between 2003-2017 were included.
