Ultrasound Blood-Brain Barrier Opening and Aducanumab in Alzheimer's Disease: A Systematic Review and Meta-Analysis.

The blood-brain barrier (BBB) presents a significant challenge in treating Alzheimer's disease, as it restricts the delivery of therapeutic medications to brain tissue. Reversible breaking of the BBB using low-intensity focused ultrasound guided by magnetic resonance imaging (MRI) may benefit patients with Alzheimer's disease and other neurological illnesses, such as brain tumors, amyotrophic lateral sclerosis, and Parkinson's disease. This systematic study and meta-analysis aimed to assess aducanumab and the ultrasonography of BBB opening in Alzheimer's patients.
