It’s intended to enable more personalized treatment driven by that data.

Amyloid and tau proteins are both involved in the disease pathology of Alzheimer’s disease.

But tau is becoming better understood, as investigational tau imaging agents offer the ability to visualize its presence in the brain.

Saluda Medical Pty. Ltd., of Artarmon, Australia, made waves in 2019, winning the CE mark for its Evoke closed-loop spinal cord stimulation (SCS) system. The good news kept coming following the publication of results from a pivotal study in The Lancet Neurology.
