👉 A term used in medicine that refers to a condition where there is an imbalance or deficiency of blood flow in the brain, usually due to a blockage or obstruction in the vessels supplying the brain. This can lead to symptoms such as difficulty concentrating, confusion, and even seizures. The exact cause of filibranchia is not fully understood but it may be caused by changes in the blood-brain barrier that allow certain substances to enter the brain instead of being filtered out through the blood vessels.
