Objectives: Migraine is a risk factor for stroke, which might be explained by a higher prevalence in anatomical variants in the circle of Willis (CoW). Here, we compared the presence of CoW variants in patients with stroke with and without migraine.
Materials And Methods: Participants were recruited from the prospective Dutch acute Stroke Study.
Article Synopsis
- Researchers wanted to see if a medicine called valproate could help protect the brain after an injury called subarachnoid hemorrhage (SAH) in rats.
- They tested valproate on rats and found that it reduced the growth of brain damage when they induced something called spreading depolarizations (SDs).
- The study concluded that valproate might help limit brain injury after SAH, but more research is needed to understand how it works.
Article Synopsis
- Delayed cerebral ischemia (DCI) is a condition that affects about one-third of people who have a certain type of brain bleed called aneurysmal subarachnoid hemorrhage (aSAH).
- Researchers wanted to see how certain medications that affect a brain process called spreading depolarization (SD) might influence DCI and patient recovery.
- They found that taking SD-inhibiting drugs might help reduce DCI, but it didn't seem to improve the overall health outcomes of patients after three months.
Article Synopsis
- Scientists wanted to see if spreading depolarizations (a brain issue) make brain damage worse after some people have bleeding in the brain from an aneurysm.
- They did tests on rats where they caused brain bleeding and then checked how much damage occurred after giving them different treatments.
- The results showed that rats with spreading depolarizations had much more brain damage than those without, showing that these brain issues can make injuries worse after bleeding.
Article Synopsis
- New brain imaging techniques using MRI can help doctors understand brain problems like migraines and strokes better!
- Two specific types of MRI scans were tested on rat brains to see how well they detect changes during spreading depolarizations (SDs) in the brain!
- These new scans showed more detailed and clearer results compared to older scanning methods, helping scientists learn about brain activity more effectively!
