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: 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.
Background: Africa has a growing burden of stroke with associated high morbidity and a 3-year fatality rate of 84%. Cardiac disease contributes to stroke occurrence and outcomes, but the precise relationship of abnormalities as noted on a cheap and widely available test, the electrocardiogram (ECG), and acute stroke outcomes have not been previously characterized in Africans.
Objectives: The study assessed the prevalence and prognoses of various ECG abnormalities among African acute stroke patients encountered in a multisite, cross-national epidemiologic study.
