If you injure your elbow, surgery can help. If you lose a leg, prostheses are available. But problems within the brain are more difficult to treat, and for stroke victims rehabilitation is largely left to the body’s own repair mechanisms. BrainQ aims to change that with a device that stimulates the damaged part of the brain and promotes self-repair, showing enough improvement in studies to warrant a Breakthrough Device certification from the FDA — and the company has just raised $40M to take it to market.
It should be said at the outset that doubting the efficacy of some brainwave-emitting miracle device is natural. And in fact when I spoke with BrainQ’s founder Yotam Drechsler, he reminded me of the last time we’d talked — back in 2017, at which time I “expressed strong skepticism.”
No hard feelings — the tech was largely notional then, he admitted — but since that time the team has continued its work, raised some money, and what was a promising if not well supported thesis then has turned into one backed by firsthand data and clinical outcomes. The resulting system could be the biggest improvement to stroke therapy in decades or more.
Strokes can result in various obvious impairments, such as grip strength or coordination, but of course the injury is not to the hand or leg itself, it is to the networks in the brain that govern those parts. But medical science has no method for directly rebuilding those networks — the (Read more...)
