Blood-Brain Barrier Market to Reach USD 3.2 Billion by 2034, Growing at 12.9% CAGR

Introduction
The blood-brain barrier (BBB) is a highly selective membrane that protects the brain from toxins and pathogens while regulating the transport of nutrients. While essential for brain health, this barrier presents a formidable challenge for drug delivery, limiting the effectiveness of therapies for neurological disorders such as Alzheimer's disease, Parkinson's disease, glioblastoma, epilepsy, and multiple sclerosis.

To overcome these challenges, researchers and biopharmaceutical companies are pioneering innovative drug delivery approaches, including nanotechnology, focused ultrasound, receptor-mediated transport, and novel carrier systems. With neurological diseases on the rise worldwide, the blood-brain barrier market is entering a new growth phase, fueled by investments in drug development, precision medicine, and advanced delivery technologies.
