702's Gugs Mhlungu spoke to Dr. Patty Francis, President of the Neurological Association of South Africa.
Listen to their conversation in the audio clip below.
Many strokes don't arrive unannounced; your body may be trying to alert you days or even weeks in advance.
Francis says that a stroke is most often caused by a clot that blocks blood flow to the brain, but in some cases, a burst blood vessel is to blame.
She explains that while the latter is more dramatic and sends people to the emergency room, the former (which accounts for 85% of cases) is more likely to be ignored until it’s too late.
Francis notes that signs of a stroke can often appear and then disappear, which is why many people miss them.
These so-called "mini-strokes" or TIAs (transient ischemic attacks) can occur up to seven days before a major stroke.
Symptoms might include temporary speech issues, dizziness, or numbness and changes in vision - all of which demand urgent care.
Francis emphasises that lifestyle factors such as poor sleep, smoking, and lack of exercise continue to drive up stroke risk, especially among younger people.
She adds that chronic conditions like hypertension, diabetes, and high cholesterol also play a significant role, particularly in sub-Saharan Africa.
Francis also highlighted that women on oral contraceptives and people living with untreated infections like HIV or syphilis are increasingly vulnerable.
