Why have BBB-targeted therapeutic strategies failed to translate into effective AD treatments?

OPEN

The abstract notes that current AD treatments don't change disease course, potentially due to poor brain drug delivery, yet doesn't explain why BBB-focused approaches haven't succeeded. Understanding these failures is essential for developing effective BBB-based therapeutics.
