The blood-brain barrier (BBB) is a really important part of our brain. You can think of it like a special gate that lets certain things in while keeping bad stuff out.
But this protective feature can make it tough to treat brain diseases. Here’s why:
Hard to Get Medicine Through: Many medicines can't pass through the BBB easily, which makes them less helpful for brain problems.
Finding the Right Spot: Even if medications do get through, it can be tricky to get them to the exact part of the brain that needs help.
Risk of Unwanted Effects: Some medicines made for other body parts might not work well in the brain, causing side effects we don’t want.
So, while the BBB is great for protecting our brain, it also makes treating brain illnesses a real challenge.
