Arterial ischemic stroke (AIS) in young adults is a significant public health concern. This study identified diverse causes, with cardio-embolic and large artery atherosclerosis being most common, highlighting lifestyle changes contributing to early risk factors.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- Ischemic stroke in young adults (18-50 years) presents a significant public health challenge, leading to disability and impacting quality of life.
- Traditional vascular risk factors are increasingly prevalent in younger populations due to lifestyle changes.
Purpose of the Study:
- To determine the risk factors and etiological causes of arterial ischemic stroke (AIS) in young Tunisian adults.
- To analyze the specific patterns of stroke in this demographic within a defined region.
Main Methods:
- A 5-year retrospective study (2015-2020) included 200 young adults diagnosed with AIS.
- Standardized investigations included biological tests, brain imaging, carotid ultrasound, and cardiac assessment.
- Etiology was classified using the TOAST criteria.
Main Results:
- The mean age of patients was 41.37 years.
- Definite causes were identified in 60% of cases, with cardio-embolic (19%) and large artery atherosclerosis (11.5%) being the most frequent.
- Etiology remained undetermined in 40% of patients, including incomplete investigations and multiple potential mechanisms.
Conclusions:
- A diverse range of etiologies contribute to AIS in young Tunisian adults.
- Lifestyle changes are linked to early onset of traditional vascular risk factors.
- Rheumatic heart disease is a notable cause of AIS in the studied population.
