[Reporter Luo Bi/Taipei Report] Young people without high blood pressure, high blood sugar or high blood lipids may also have sudden cerebral hemorrhage. Shi Yizhong, director of the Department of Cardiology at Lian On Clinic, pointed out that if people in their 30s and 40s do not have obvious high blood pressure problems but suffer cerebral hemorrhage, doctors will further clarify whether there are structural abnormalities of cerebral blood vessels, including cerebral aneurysms and cerebral arteriovenous malformations. Both abnormalities may have no obvious symptoms before rupture. If you suddenly have a severe headache that is different from the past, you should seek medical treatment as soon as possible.

Shi Yizhong explained that a cerebral aneurysm is an abnormality caused by the local weakness of the blood vessel wall and its outward bulging. When the pressure on the blood vessel exceeds the load, it may rupture and bleed. Cerebral arteriovenous malformations lack a normal microvascular network between arteries and veins. Blood flows directly from arteries into veins, which increases the load on veins that originally bear lower pressure, and may also expand and rupture.

"Looking healthy at ordinary times" does not necessarily mean that these two vascular abnormalities can be detected from the body. Shi Yizhong said that when a cerebral aneurysm or cerebral arteriovenous malformation ruptures, a severe headache may suddenly occur. Some people describe it as "the most painful headache in their life." It may also be accompanied by vomiting, dizziness or fainting. If the headache comes on suddenly and is severe, you should seek medical treatment immediately; even if there are no typical symptoms mentioned above, as long as you have a headache of unknown origin and that is obviously different from the past, you should also ask a neurologist for evaluation.

No matter your age or whether you have high blood pressure or not, you should measure your blood pressure regularly to understand your daily values. The picture is a situational photo, and the people in the picture have nothing to do with this article. (Picture taken from shutterstock)

Who should consider a cerebrovascular examination? Shi Yizhong pointed out that if two of your parents or siblings have been diagnosed with cerebral aneurysm or subarachnoid hemorrhage; or you have polycystic kidney disease, and someone in your family has progressed to dialysis due to polycystic kidney disease, you can discuss with your doctor whether to undergo cerebral angiography (MRA) to understand whether there are any abnormalities in the vascular structure. This is a recommendation to discuss testing with your doctor for specific risk situations, and you should not rely on a headache to diagnose a brain aneurysm on your own.

Shi Yizhong reminded that no matter your age or whether you have high blood pressure or not, you can measure your blood pressure regularly to understand your daily values. Sickness, staying up late, mood swings, or taking some cold medicines may affect blood pressure. If you have headaches, dizziness, etc., you can also measure it and observe the difference from usual times. People with known cerebral aneurysms or other structural abnormalities of cerebral blood vessels should pay more attention to blood pressure control. However, sudden severe headache cannot be observed by measuring blood pressure alone. You should seek medical treatment as soon as possible to clarify the cause.
