U.S. health care system unprepared to move future Alzheimer's treatment into rapid clinical use

Advanced clinical trials are underway for at least 10 investigational therapies that have shown promise in slowing or blocking development of Alzheimer's disease, creating hope that a preventive strategy may be in reach. But a new study warns that the U.S. health care system lacks the capacity to rapidly move such a treatment into wide clinical use, a shortcoming that could leave millions of people without access to transformative care if such a breakthrough occurs.
