Article Synopsis
- The study investigates the role of cerebrovascular disease in HIV-associated neurocognitive disorder (HAND) among a specific black population in Nigeria, comparing participants with and without cognitive impairments using CT perfusion imaging.
- It involved 27 HIV+ adults divided into impaired (18) and unimpaired (9) groups, measuring brain blood flow and volume across key regions, and found significant differences in regional blood flow variability between the two groups.
- The findings suggest that CT perfusion imaging can effectively show cerebral perfusion changes linked to HAND, highlighting its potential as a resource for addressing HIV impacts in Africa, where the epidemic is most severe.
Background: Stroke is a leading cause of disability and mortality worldwide, but little is known about the contribution of secondhand smoke exposure (SHSE) to stroke epidemiology among indigenous Africans.
Objective: To evaluate the association of SHSE with stroke among indigenous Africans.
Methods: We analyzed the relationship of SHSE with stroke among 2990 case-control pairs of adults who had never smoked (identified in the SIREN study) using conditional logistic regression at a two-sided P < 0.
Background: We evaluated the characteristics of carotid and vertebral atherosclerosis in indigenous West Africans with stroke.
Methodology: Of the 3778stroke patients recruited between 01/2014 and 08/2017, 1070 (28.3%) received carotid and vertebral artery evaluation with B-mode Ultrasound.
Background And Purpose: To identify the qualitative and quantitative contributions of conventional risk factors for occurrence of ischemic stroke and its key pathophysiologic subtypes among West Africans.
Methods: The SIREN (Stroke Investigative Research and Educational Network) is a multicenter, case-control study involving 15 sites in Ghana and Nigeria. Cases include adults aged ≥18 years with ischemic stroke who were etiologically subtyped using the A-S-C-O-D classification into atherosclerosis, small-vessel occlusion, cardiac pathology, other causes, and dissection.
Article Synopsis
- Stroke is a leading cause of death and disability in sub-Saharan Africa, prompting a research initiative aimed at understanding its risk factors in Ghana and Nigeria.
- The study involved focus groups with stroke survivors, caregivers, healthcare professionals, and community leaders to explore attitudes and beliefs about stroke.
- Key findings reveal community fears and misconceptions about stroke, leading to recommendations for improving treatment and supporting community engagement in stroke awareness and education.
Background: It is crucial to assess genomic literacy related to stroke among Africans in preparation for the ethical, legal and societal implications of the genetic revolution which has begun in Africa.
Objective: To assess the knowledge, attitudes and practices (KAP) of West Africans about stroke genetic studies.
Methods: A comparative cross-sectional study was conducted among stroke patients and stroke-free controls recruited across 15 sites in Ghana and Nigeria.
Background: Low-field (LF) magnetic resonance imaging (MRI) is a technology that is widely used in resource-limited settings for clinical imaging. The images produced, even though of low resolution with noise and artefacts, provide valuable information and guidance for patient assessment and treatment. This study shows a spectrum of MRI artefacts that affect image quality during routine clinical neuroradiology practice using LF MRI in a Nigerian hospital and suggests ways to avoid them.

We developed the ACCESS application and determined its inter-rater and intra-rater reliability in the Stroke Investigative Research and Educational Network (SIREN) study to assess its suitability for multicenter studies.
Methods: One hundred randomly selected stroke imaging reports from 5 SIREN sites were re-evaluated by 4 trained independent raters to determine the inter-rater reliability of the ACCESS (version 12.
