While headaches can be a general ailment, it could be because you slept in an uncomfortable position, did not have good food, are stressed, etc. However, not all headaches should be ignored. Some could be signs of dangerous conditions, if left ignored, could cause permanent damage to your body. According to MedlinePlus, emergency causes of headaches could be due to abnormal connections between the arteries and veins in the brain, that form before birth. This is also called arteriovenous malformation, or AVM. They could also be due to blockage of blood flow in one part of the brain, which is a stroke. Another reason could be a blood vessel breaks open and causes internal bleeding in the brain, which is called an aneurysm. Dr Sermed Mezher, a registered general practitioner based in London, takes to social media and explains that these are different kinds of headaches that one must pay attention to. What is Brain Aneurysm? Blood vessels carry our blood to our vital organs. Sometimes, the wall of a blood vessel can become weak. The NHS, a health organization, explains it as a bulge. When blood flows through this weak spot, the pressure makes it push outwards, creating that balloon shape. These weak spots can happen in blood vessels all over your body, but they are most common in the main artery from your heart and in the blood vessels of your brain. Critical Signs of a Brain Aneurysm to Watch For However, if it is a brain aneurysm, then how do we tell them apart from normal headaches? Mezher wants everyone to know the important signs that could mean a brain aneurysm. It's vital to be aware of these because, for about one person out of every 10,000 each year, these aneurysms can burst. When they burst, it can cause a stroke. One key sign is a very sudden and very bad headache, often called a "thunderclap" headache. People often describe it as feeling like they've been hit hard on the head, even when no one is there. This kind of headache is often linked to a specific type of aneurysm in the brain. Sometimes, before an aneurysm breaks open, your body might give you a warning. This warning can come in the form of what doctors call "sentinel headaches." These are new headaches that feel different from your usual ones. They might be more painful and stick around longer. Dr. Mezher says these sentinel headaches can happen a few weeks before a more serious rupture. So, if you suddenly start getting headaches that are much worse or don't go away like your normal headaches, it's a good idea to get them checked out by a doctor. Why Is Early Detection Important For Brain Aneurysm Brain aneurysms might be more common than you think. Dr. Mezher mentioned that they can affect about one in every thirty people at some point in their lives. That's a significant number of people! While the signs he talked about, like bad headaches and vision problems, can also be caused by other health issues, it's still really important to get them checked by a doctor. Finding a brain aneurysm early can make a big difference in how it's managed and treated, potentially preventing serious problems later on. What Are Some Risk Factors? Several things can make it more likely for a brain aneurysm to burst. Dr. Mezher pointed out that the bigger the aneurysm, the higher the risk. Some risk factors include having high blood pressure, smoking cigarettes, or having a family history of aneurysms can increase the chances of a rupture. This is why finding aneurysms early is so important. Sometimes, they are found during scans done for other reasons. When found before they burst, doctors can monitor or treat them to prevent serious outcomes. Being aware of the signs, getting screened if you are at high risk, and taking care of your heart health are all important in dealing with this rare but serious condition.
