Background
Stroke is the second leading cause of death above the age of 60 years, and the fifth leading cause in people aged 15 to 59 years old as reported by the World Health Organization global burden of diseases. Stroke in the young is particularly tragic because of the potential to create long-term disability, burden on the victims, their families, and the community at large. Despite this, there is limited data on stroke in young adults, and its risk factors in Uganda. Therefore, we determined the frequency and risk factors for stroke among young adults at Mulago hospital.
Methods
A case control study was conducted among patients presenting consecutively to the general medical wards with stroke during the study period September 2015 to March 2016. A brain Computerized Tomography scan was performed to confirm stroke and classify the stroke subtype. Controls were patients that presented to the surgical outpatient clinic with minor surgical conditions, matched for age and sex. Social demographic, clinical and laboratory characteristics were assessed for both cases and controls. Descriptive statistics including frequencies, percentages, means, and standard deviation were used to describe the social demographics of case and controls as well as the stroke types for cases. To determine risk factors for stroke, a conditional logistic regression, which accounts for matching (e.g., age and sex), was applied. Odds ratio (with 95% confidence interval) was used as a measure for associations.
Results
Among 51 patients with stroke, 39(76.5%) had ischemic stroke and 12(23.5%) had hemorrhagic stroke. The mean age was 36.8 years (SD 7.4) for stroke patients (cases) and 36.8 years (SD 6.9) for controls. Female patients predominated in both groups 56.9% in cases and 52.9% in controls. Risk factors noted were HIV infection, OR 3.57 (95% CI 1.16–10.96), elevated waist to hip ratio, OR 11.59(95% CI 1.98–68.24) and sickle cell disease, OR 4.68 (95% CI 1.11–19.70). This study found a protective effect of oral contraceptive use for stroke OR 0.27 95% CI 0.08–0.87. There was no association between stroke and hypertension, diabetes, and hyperlipidemia.
Conclusion
Among young adults with stroke, ischemic stroke predominated over hemorrhagic stroke. Risk factors for stroke were HIV infection, elevated waist to hip ratio and sickle cell disease.

Background
Little is known about the characteristics and determinants of post-stroke cognitive impairment in residents of low- and middle-income countries. The objective of this study was to determine the frequencies, patterns, and risk factors for cognitive impairment in a cross-sectional study of consecutive stroke patients cared for at Uganda’s Mulago Hospital, located in sub-Saharan Africa.
Methods
131 patients were enrolled a minimum of 3-months after hospital admission for stroke. A questionnaire, clinical examination findings, and laboratory test results were used to collect demographic information and data on vascular risk factors and clinical characteristics. Independent predictor variables associated with cognitive impairment were ascertained. Stroke impairments, disability, and handicap were assessed using the National Institute of Health Stroke Scale (NIHSS), Barthel Index (BI), and modified Rankin scale (mRS), respectively. The Montreal Cognitive Assessment (MoCA) was used to assess participants’ cognitive function. Stepwise multiple logistic regression was used to identify variables independently associated with cognitive impairment.
Results
The overall mean MoCA score was 11.7-points (range 0.0–28.0-points) for 128 patients with available data of whom 66.4% were categorized as cognitively impaired (MoCA < 19-points). Increasing age (OR 1.04, 95% CI 1.00-1.07; p = 0.026), low level of education (OR 3.23, 95% CI 1.25–8.33; p = 0.016), functional handicap (mRS 3–5; OR 1.84, 95% CI 1.28–2.63; p < 0.001) and high LDL cholesterol (OR 2.74, 95% CI 1.14–6.56; p = 0.024) were independently associated with cognitive impairment.
Conclusions
Our findings highlight the high burden and need for awareness of cognitive impairment in post stroke populations in the sub-Saharan region and serve to emphasize the importance of detailed cognitive assessment as part of routine clinical evaluation of patients who have had a stroke.

A 6-month, prospective randomized controlled trial of the TargetEd MAnageMent (TEAM) intervention vs. enhanced treatment as usual among Ugandans at risk for stroke
2025
Among low and middle-income countries, especially in Sub-Saharan Africa, the stroke burden is severe, with increasing trends in stroke incidence, prevalence, and mortality.
This 6-month, prospective randomized controlled trial (RCT) compared a novel stroke risk reduction approach (TargetEd manAgeMent Intervention (TEAM)) vs. Enhanced Treatment as Usual (ETAU) in 247 Ugandans at risk for stroke.
Participants, enrolled across 3 Ugandan sites, were adults with high stroke risk. The primary outcome was a change in systolic blood pressure (SBP) from baseline to 6-month follow-up. Secondary outcomes included changes from baseline to 6 months on diastolic BP (DBP), serum lipids, glycosylated hemoglobin (HbA1c), self-efficacy and stress.
The mean sample age was 55.4 (±SD = 12.0) with majority being women (n = 168, 68%). In addition to hypertension, the most common risk factors were hyperlipidemia (n = 199, 80.6%) and obesity (n = 98, 39.7%). Overall mean SBP and DBP at baseline were 143.0 (SD = 19.8, range 94.5-206) and 89.3 (SD = 14.0, range 61-136) respectively. In TEAM, SBP significantly improved from 145.7 (±21.5) at baseline to137.4 (±18.1) at 6-months vs. change from 141.9 (±18.4) to 141.1 (±21.9) for ETAU (p = 0.031). There were similar reductions in DBP favoring TEAM (p = .012). Compared to ETAU, TEAM showed improved physical activity (p = .017), self-efficacy (p < .001) and stress (p = .014).
There is a need for effective and practical approaches to reduce stroke burden in Sub-Saharan Africa. Inclusion of the TEAM approach in primary care seems to be a pragmatic and effective way to potentially reduce stroke burden in Uganda.

Stroke burden is rapidly increasing globally. Modifiable risk factors offer an opportunity to intervene, and targeting hypertension is a key actionable target for stroke risk reduction in sub-Saharan Africa. This 3-site planned randomized controlled trial builds on promising preliminary data.
A total of 246 Ugandan adults will be recruited randomized to experimental intervention vs. enhanced treatment control. Intervention participants will receive six weekly group-format stroke risk reduction self-management training sessions, and the controls will receive information on cardiovascular risk. The primary study outcome is systolic B.P. measured at baseline, 13-week, 24 weeks (6 months). Secondary outcomes include other biological and behavioral stroke risk factors.
The curriculum-guided self-management TargetEd MAnageMent Intervention (TEAM) program is anticipated to reduce the stroke burden in Uganda.

Barriers to epilepsy care in Central Uganda, a qualitative interview and focus group study involving PLWE and their caregivers
2019
Background
Epilepsy is a common neurological disease with substantial impact on the subject and their caretakers. This exploratory study identified barriers to care for persons living with epilepsy (PLWE) to develop a culturally acceptable nurse led self-management intervention for PLWE previously developed in the United States.
Methods
The study involving 48 participants (31 PLWE and 17 caregivers) with in depth interviews and focus groups was conducted. We obtained insights into barriers to care in PLWE and their caregivers. Using a thematic analytic procedure emphasizing the dominant themes the qualitative responses were analyzed. Median age of PLWE was 24 years (IQR 19–30), and10 (52.6%) were male. The median age of epilepsy onset was 12 years (IQR 6–18), range of 1–37 years. The median age of caregivers was 50 years (IQR 45–50.5), with a range of 18–78 years. Seventy five percent of caregivers (6/8) were females.
Results
Three major areas of perceived barriers involving individual, family or community and provider and healthcare system barriers to epilepsy care emerged. Individual factors like limited epilepsy knowledge and medication non-adherence were reported to be key barriers to epilepsy care. Caregiver burden and lack of family support as well as poor health care access were identified from the family and health care systems.
Conclusions
The main barrier to epilepsy care is limited epilepsy knowledge in PLWE and their caregivers. Improving epilepsy care awareness and knowledge within communities and appropriate health care provider service for epilepsy would help reduce epilepsy barriers and improve care.

Effects of educational intervention on knowledge of Full Outline of Un-Responsiveness score among health workers in uganda: a quasi -experimental pilot study
2025
Background
The Full Outline of Un-Responsiveness (FOUR) score is a new and better coma grading scale in critically ill patients. However, there is a paucity of data on its knowledge among health workers in sub-Saharan Africa. This study assessed the effects of an educational intervention on knowledge of FOUR Score among healthworkers at a Regional Referral Hospital in Southwestern Uganda.
Methods
This was a one-group quasi-experimental study among conveniently sampled health workers attending to critically ill patients. Using a pretested questionnaire, data was collected pre and post intervention. Participants with low and moderate pre-test knowledge attended a theory session of 45-minutes and hands on sessions using the FOUR Score reference chart for one week, on ward. The post-test data was collected for all trained participants seven days after training. Data was analysed using STATA-17.
Results
Of the 146 health workers (HWs) recruited, 50.7% and 45.2% were nurses and doctors, respectively. Over 113 (77.0%) were degree holders and 114 (78.1%) had no prior FOUR Score training. The median knowledge score was 8 (34.8%) and 19 (82.6%) in the pre- and post-test, respectively. A Wilcoxon Signed-Rank test showed a significant knowledge score difference in the median pre- and post-test (Z = 10.4;
p
< 0.001). Higher level of education (X2 [1] = 10.3,
P
= 0.016), working in ICU (X2 [2] = 13.8,
P
= 0.001), and prior FOUR Score training (Z = 6.3,
P
< 0.001) were significantly associated with high pre-test knowledge score but were not significant in the post-test.
Conclusion
This educational intervention was effective in increasing the knowledge of healthworkers regarding the FOUR score, indicating that it can be easily learned and mastered. When properly done, this intervention could potentially improve the management of critically ill patient in similar (low- and middle-income countries) settings.

People of all ages are affected by epilepsy, a prevalent chronic brain illness that is primarily found in underdeveloped nations. It is very necessary to implement epilepsy self-management techniques to support individuals with epilepsy in order to impact outcomes related to epilepsy. The purpose of this 2-site randomised controlled experiment is to investigate this further, based on encouraging preliminary evidence.
A total of 188 adult people with epilepsy (PWE) attending the neurology clinics at Mulago and Mbarara hospitals and consent to participate in the study will be recruited. They will be randomised into intervention versus enhanced treatment control (eTAU) study groups. The intervention group will receive 12-week \"intensive\" educational sessions and a 12-week remotely accessed telephone follow-up stage. The controls will continue in their usual care supplemented by written materials on epilepsy in their preferred language and tailored to the reading level of most patients at the clinic. SMART-U consists of 2 main components: a 12-week \"intensive\" group format stage and a 12-week remotely accessed telephone follow-up stage. SMART-U will be assessed for acceptability, fidelity, and efficacy compared to eTAU. The primary study outcome is the mean change in cumulative past 24-week seizure frequency (24 weeks prior to the study baseline compared to the 24-week follow-up). Seizure frequency will be via self-report with corroboration by family/support system informants whenever possible. Participants will self-report the seizure frequency (numeric count) that they experienced between baseline and 13 weeks and again between 13 and 24 weeks, and the mean change from baseline to 24 weeks in QOL.
The curriculum-guided Self-Management intervention for Reducing The epilepsy burden among Ugandans (SMART-U) program is anticipated to reduce the epilepsy burden seizure frequency and improve other health outcomes, including depression, functional status and health resource use.

Diagnosing dementia remains challenging in low-income settings due to limited diagnostic options and the absence of definitive biomarkers. The use of brain MRI in the diagnosis of dementia is infrequent in Uganda, and even when it is used, subtle findings like mild regional atrophy are often overlooked, despite being crucial for imaging diagnosis.
The purpose of this study was to explore the perceptions and practices of imaging personnel and physicians regarding the use of brain MRI as a diagnostic approach for dementia in Uganda.
This was an exploratory qualitative study involving radiologists, technologists, senior house officers and psychiatrists. The participants were 25 in total. Data was collected through key informant interviews and focus group discussions and analyzed thematically using an inductive approach.
The study revealed three key themes: Brain MRI Practices for Diagnosing Dementia, Facilitators of Appropriate MRI Use, and Barriers to Appropriate Use of Brain MRI. Sub-themes under these themes included cost considerations, poor and good MRI practices, MRI as a standard operating procedure, positive attitudes towards brain MRI, and barriers such as structural, financial, operational, technical, and patient-related issues. Participants acknowledged the high accuracy and superiority of brain MRI for diagnosing dementia and recognized it as the standard of care. However, its use in Uganda is limited due to high costs, restricted access, mechanical failures, patient claustrophobia, myths and misconceptions, and interpretation difficulties by radiologists and inappropriate protocols by technologists.
The study identifies barriers to effective brain MRI use for dementia diagnosis in Uganda, including limited training, high costs, and uneven equipment distribution. Despite this, providers are positive about MRI adoption. Enhancing training, awareness, and phased rollouts can improve outcomes. Future research should focus on similar low-resource settings for validation.

Background
Malaria during pregnancy leads to many deaths in Africa. COVID-19 contributed to more malaria cases due to interruptions in prevention efforts. Intermittent presumptive treatment (IPTP) is an effective malaria prevention strategy for pregnant women, but adoption barriers still exist. The study aim was to explore barriers to the adoption of IPTP at Kawempe National Referral Hospital (KNRH) Uganda.
Methods
In a qualitative study design, data was collected using focus group discussions. A total of 37 postpartum mothers were interviewed in six focus group discussions. The interviews were conducted using a structured guide to explore barriers to IPTP implementation at KNRH. The data was transcribed, coded, and analysed using NVivo 10.
Results
The study found that mothers lacked adequate knowledge about IPTP, faced socioeconomic and cultural constraints, fear of side effects, a high pill burden, and experience of health system challenges as major themes of barriers to optimal IPTP use.
Conclusions and recommendations
Challenges in the service delivery and inadequate information in regard to importance and expected side effects were identified by the users as the major barriers to IPTP delivery in public health care setting. Improving delivery of focused health education talks and health work attitude and delivery chain for IPTP in the health facilities are recommended to increase its uptake.

Evidence supporting secondary stroke in sub-Saharan Africa is scarce. This study describes the incidence of stroke recurrence and associated risk factors in sub-Saharan Africa.
Scientific databases were systematically searched from January 2000 to December 2022 for population-based observational studies, case-control or cohort studies of recurrent stroke involving adults aged 18 years and above in sub-Saharan Africa (SSA). We assessed the quality of the eligible studies using the Critical Appraisal Skills Program (CASP) checklist for observational studies.
Six studies met the inclusion criteria and were included in this study. Stroke recurrence rates in SSA ranged from 9.4% to 25%. Majority of the studies were conducted from Western Africa and showed that stroke recurrence rates are high within sub-Saharan Africa ranging from 2% to 25%. The known stroke risk factors such as hypertension, chronic alcohol consumption, etc., remained the leading causes of stroke recurrence. The studies reported a higher mortality rate ranging from 20.5 -23% among those with recurrent strokes compared to primary strokes.
This systematic review is an update and summary of the available literature on stroke recurrence within sub-Saharan Africa. Further studies are warranted to assess the outcomes and burden of stroke recurrence in SSA.
