Young people can also have strokes, but the incidence is still much lower compared to older people. The causes of stroke in young people are different from those in the elderly. Stroke in the elderly is mostly caused by atherosclerotic lesions of the blood vessels, caused by what we often call the three highs (high blood pressure, high blood sugar and high blood lipids). In contrast, most strokes in young people are caused by heart problems, and the more common cause is unclosed foramen ovale. Due to congenital developmental abnormalities, the foramen ovale is not closed in some people, and under certain triggers, blood clots from veins enter the cerebral vessels through the foramen ovale, leading to cerebral vessel blockage and stroke attack. The main treatment is to block the foramen ovale, which effectively prevents the next recurrence. The treatment of patent foramen ovale is completely different from that of atherosclerotic stroke, which is treated with anti-atherosclerotic therapy and requires long-term antiplatelet and lipid-lowering drugs. Of course, the etiology of stroke in young people is very complex and varied, including early onset atherosclerosis, arterial entrapment, and vasculitis, among others. Therefore, the most important thing is to identify the cause of stroke in young people and to treat the cause in order to prevent recurrence. The prognosis for stroke in young people is also better than in older people, as young people recover well and usually have only minor sequelae. Finally, let’s look at an example of a stroke in a young person. This is a 28-year-old male with a design job and an obese body type. He woke up in the morning with a sudden feeling of dizziness, unstable walking, and inflexibility in his right hand. His family rushed him to the hospital, where the examination suggested cerebral infarction. Six months ago, he was found to be hyperglycemic during a physical examination and was taking glucose-lowering medication irregularly. This young man had the typical three highs: hypertension, hyperglycemia, and hyperlipidemia, plus obesity, which are the most common risk factors for cerebrovascular disease. Further high-resolution MRI revealed cerebral atherosclerotic plaques. Of course we also screened for cardiac causes and found no common cardiogenic stroke etiologies such as atrial fibrillation and oval foramen may not be present. Therefore, this patient’s diagnosis was clear: cerebral infarction with cerebral atherosclerosis, risk factors such as three highs and body type obesity. In the future, he must take antiplatelet drugs and lipid-lowering drugs regularly for a long time, and he must control blood pressure, blood sugar and blood lipids very strictly. When he was discharged from the hospital, this young man’s symptoms improved significantly, his dizziness was better and he could walk normally, but he still had some degree of right hand inflexibility left behind, weakness in brushing his teeth in the morning, and crooked writing. Of course, he is still in the acute stage of cerebral infarction, and after he is discharged from the hospital, he can further recover his hand function by strengthening his rehabilitation exercises, and we wish him a speedy recovery.
