Abstract
BACKGROUND Cerebrovascular disease is a significant cause of morbidity and mortality in Africa, and using neuroimaging techniques has improved the diagnosis and management of this disease. However, there is a lack of comprehensive reviews of the role and effectiveness of neuroimaging techniques in the African context. METHODS We reviewed the literature to evaluate the role of neuroimaging in diagnosing and managing cerebrovascular disease in Africa. Our search included electronic databases such as PubMed, Scopus, and Google Scholar from 2000 to April 2023. We included peer-reviewed studies written in English that reported on the use of neuroimaging in diagnosing and managing cerebrovascular disease in African populations. We excluded non-peer-reviewed articles, letters, editorials, and studies unrelated to cerebrovascular disease, neuroimaging, or Africa. A total of 102 potential articles were identified; after applying our exclusion criteria and removing duplicated articles, 51 articles were reviewed. RESULTS Our findings suggest that neuroimaging techniques such as CT, MRI, and Skull x-ray play a crucial role in diagnosing and managing cerebrovascular disease in Africa. CT and MRI were the most commonly used techniques, with CT being more widely available and less expensive than MRI. However, challenges to using neuroimaging in Africa include the high cost of equipment and maintenance, lack of trained personnel, and inadequate infrastructure. These challenges limit the widespread use of neuroimaging in diagnosing and managing cerebrovascular disease in Africa. CONCLUSION Neuroimaging techniques are essential for diagnosing and managing cerebrovascular disease in Africa, but challenges to their use must be addressed to improve healthcare outcomes. Our policy recommendations can help improve the availability and accessibility of neuroimaging services in Africa.

Abstract
BACKGROUND AND AIMS Cerebral small vessel disease (CSVD) is the main cause of intracerebral hemorrhage (ICH) in older individuals but has not been systematically studied in younger people. We aimed to evaluate the prevalence and characteristics of CSVD in young adults with symptomatic ICH. METHODS We conducted a cohort study of consecutive adults aged 18-50 years with non-traumatic ICH. All patients were evaluated with brain and vascular imaging. Using validated imaging markers (cerebral microbleeds (CMBs), white matter hyperintensities and/or lacunes), patients were categorized as having CSVD-related ICH or non-CSVD-related ICH. Factors associated with CSVD were evaluated using multivariable analyses. CSVD subtypes were characterized using pre-specified criteria. RESULTS Of 146 young adults with ICH (mean age = 37.7), CSVD was present in 41 patients (28.1%; 95% confidence interval (CI) = 21.0-36.1). In multivariable analysis, older age, male sex, and hypertension were independently associated with the presence of CSVD. Deep perforator arteriopathy (48.8%) and mixed CSVD (31.7%) were the most common CSVD subtypes. CONCLUSION Our results suggest that CSVD is a frequent cause of ICH in young adults and provide new insights into the characterization of the disease. These findings may have important implications since the treatment and management differ from other causes of ICH.
