Stroke & Cerebrovascular Disease Dataset

Abstract

This dataset provides 30,000 simulated stroke records (10,000 per scenario) of adults presenting with acute stroke in sub-Saharan Africa. Each record contains 50+ variables including risk factors, stroke type, severity (NIHSS, GCS), imaging, treatment, complications, and outcomes (30-day mortality, mRS). Three settings: tertiary hospital (28% mortality), district hospital (41%), and rural facility (57%).

1. Introduction

Stroke in Africa has an annual incidence up to 316/100K person-years, with 30-day case fatality rates of ~30% (range 18-40%) and 90-day mortality reaching 50% at some centres. Approximately 60% of strokes are ischaemic and 32% haemorrhagic β€” a higher proportion of haemorrhagic stroke than in HICs. Mean age at onset is ~59 years, 10 years younger than Western populations. Hypertension is the dominant risk factor with BP control rates <10% in many SSA populations. CT scanning and thrombolysis are virtually unavailable outside tertiary centres.

This dataset is entirely simulated. It must not be used for clinical decision-making.

4. Validation

Validation Report

Key validation checks:

  • Mortality gradient: 28% β†’ 41% β†’ 57% βœ“
  • Stroke type: 60% ischaemic, 32% ICH βœ“
  • Hypertension: 75% prevalence βœ“
  • CT access: 80% tertiary vs 0% district/rural βœ“
  • ICH mortality > ischaemic βœ“
  • Mean age ~59 βœ“

5. Usage

from datasets import load_dataset
dataset = load_dataset("electricsheepafrica/stroke-cerebrovascular-disease", "district_hospital")
df = dataset["train"].to_pandas()

6. Limitations

  • Simulated: Not from real stroke registries.
  • No neuroimaging: No actual CT/MRI data.
  • No longitudinal: 30-day outcome only, no long-term follow-up.
  • No rehabilitation: Limited rehab outcome data.
  • Simplified: No detailed vascular territory mapping.
