Review examines a blood-vessel procedure for chronic brain bleeding

This human-focused review examines chronic subdural hematoma, a blood collection around the brain that is more common in older adults. It describes evidence for middle meningeal artery embolization, a procedure intended to reduce blood flow to the membrane that can help sustain the hematoma. The review presents the procedure as a possible addition to, or alternative for, surgery in selected high-risk patients—not as a universal replacement.

Review finds timing of aneurysm repair and recovery remains uncertain

This systematic review examined 20 reports involving 11,096 adult records with aneurysmal subarachnoid hemorrhage, a type of bleeding around the brain caused by a ruptured aneurysm. Earlier aneurysm securement was associated with less bleeding before treatment, but the review found no consistent independent link between treatment timing and later disability or death. The evidence was very uncertain and does not establish a preferred treatment window.

Review links medication-raised blood pressure to better recovery in some stroke patients

A systematic review and meta-analysis examined medication-induced increases in blood pressure during the first 72 hours after certain acute ischemic strokes. Across three studies involving 366 people, those given this treatment were more likely to be functionally independent after 90 days, although the result does not establish that the treatment caused better recovery.
