A fun fact about the blood-brain barrier is that it protects the brain by blocking 98% of small molecule drugs from entering. This selective permeability is crucial for the brain's protection but presents a significant challenge in treating neurological diseases.

FAQs & Answers

  1. What does the blood-brain barrier do? The blood-brain barrier protects the brain by preventing most small molecule drugs and harmful substances from entering.
  2. Why is the blood-brain barrier important? It is crucial for maintaining the brain's environment and protecting it from toxins and pathogens.
  3. What are the challenges in drug delivery to the brain? The selective permeability of the blood-brain barrier makes it difficult for many medications to effectively reach the brain.
  4. Can medications cross the blood-brain barrier? Only a small percentage of drugs can penetrate the blood-brain barrier, which poses challenges for treating neurological diseases.
