A stroke occurs when blood flow to part of the brain is interrupted, potentially leading to brain damage. According to the World Health Organization (WHO), around 15 million people worldwide suffer a stroke each year. The risk of death depends on the type of stroke.
Patients may experience loss of vision or speech, paralysis on one side or the entire body, and confusion. Those who have had a previous stroke have a higher risk of recurrence. High blood pressure, atrial fibrillation, heart failure, myocardial infarction, and smoking are the most significant risk factors. Some strokes may be preceded by transient ischemic attacks (TIAs), also known as mini-strokes. Stroke can happen to anyone. Recognizing the early signs can help patients receive timely emergency care, reducing mortality and severe sequelae.
Sudden loss of senses. A sudden loss of senses such as vision, hearing, or touch can be an early symptom of a stroke. Stroke occurs when blood flow to the brain is interrupted, depriving brain cells of oxygen and nutrients, which can lead to various neurological deficits.
Confusion or difficulty understanding speech. Confusion is another typical sign of early-stage stroke. Patients may find it difficult to understand speech, express themselves, or put words together. These symptoms should be evaluated early, even if they disappear quickly. This may be due to a transient ischemic attack, which often precedes an actual stroke.
Unexplained headache. While there are many causes of headaches, a sudden, severe headache with no apparent reason may stem from a stroke. This type of headache can occur rapidly, unlike any previous headaches experienced. If the headache is accompanied by nausea or dizziness, it could warn of a stroke.
Changes in sensation. Feeling sleepy or having difficulty staying awake is sometimes an early sign of a stroke. Changes in sensation, such as tingling or numbness in the extremities, can also occur. While these symptoms may seem mild initially, they can worsen, so patients should not ignore them.
Vision problems. Vision problems such as double vision, blurred vision, or complete loss of vision also need attention, as these conditions also indicate an interruption in the blood supply to the brain.
Memory loss. Memory problems can indicate an early stroke, especially when accompanied by other symptoms. Patients sometimes experience temporary memory loss, difficulty remembering basic words, or even suddenly forgetting familiar objects due to abnormal blood flow reduction.
