This is the first study worldwide with the means to safely, repeatedly and reproductively open the BBB in AD, or more broadly, in any neurodegenerative disease. It is noteworthy to consider that it is only a phase I study aiming to demonstrate the feasibility of the technique in a mild form of AD. If this is the case and even in the absence of a positive effect on the lesions and symptoms it will then be possible to propose new projects aiming to associate these safe BBB opening to anti-AD drugs. In fact, this study could pave the way for further treatment venues of various neurodegenerative disease that share a brain accumulation of proteins that cannot be readily targeted in case of BBB integrity.
