I read that they've linked intracranial hypertension to problems with the veins in the brain's membrane. I get headaches from time to time - could that be it? Is it dangerous? How do you treat it?
Magnetic resonance venography is a type of scan where doctors look at how blood flows through the veins in your brain and whether something might be going wrong there. When veins aren't working properly, the pressure inside your skull increases, which causes headaches. But here's the thing: periodic headaches are usually not about that at all. Intracranial hypertension typically causes constant or very frequent headaches, often with nausea, blurred vision, and pain when you move your eyes. If you just get a headache sometimes, there could be tons of reasons: tension in your neck, stress, lack of sleep, even poor diet.
Is all this dangerous? If it really is hypertension from your veins, then yeah, you need to get it treated, because elevated pressure inside your skull can lead to problems. But you can't diagnose this from your phone - you need actual imaging and a neurologist's exam. I've been running in the mornings for years now, and I've noticed that if I slept badly or didn't drink enough water, my head hurts all day. Get a proper night's sleep or drink a liter of water, and it goes away.
You should see a doctor if your headaches start happening more often or getting worse, if nausea shows up or you have vision problems. A neurologist will listen to your symptoms, might send you for an MRI if needed, and then based on the results you'll know what's going on with your veins. Treatment depends on the diagnosis: it might just be preventive stuff, or it could be medication. So don't panic ahead of time, but definitely check in with a doctor if the problem keeps happening.
When did this pain start and how often does it happen - a few times a week or a month?
Brain veins are involved in draining blood and cerebrospinal fluid from the skull cavity. If something goes wrong in this process - for example, due to thrombosis, vessel stenosis, or impaired drainage - the pressure inside increases, and this can cause headaches, vision problems, nausea. This condition is called venous intracranial hypertension. But here's the important thing: periodic headaches are rarely actually related to this. Migraines, tension, fatigue, dehydration cause pain much more often. Without an MRI of the brain with contrast and a neurologist's consultation, you can't say for sure what's causing it.
If it really is a problem with your veins, then yeah, it needs to be treated, because a neglected condition can lead to a stroke or brain swelling. But first you need to get diagnosed - see a neurologist, describe what the pain is like (where it hurts, how long it lasts, what helps), tell them about any other symptoms. The doctor will order the necessary tests. Treatment depends on the cause: they might prescribe diuretics, medications to improve venous drainage, or in rare cases surgery is needed. Don't put off visiting the doctor if the pain gets worse or you develop dizziness, double vision, or weakness in your limbs.
