Editor's note: An earlier version of this article incorrectly stated that Eli Lilly purchased two companies from Siemens. The actual transaction was for two tracers used in detecting tau tangles. The video also misidentifies a collaboration between Eli Lilly and General Electric for similar diagnostic products. GE Healthcare is developing a tau tangle imaging test that is independent of Eli Lilly. The Fool regrets the error.
In this video, health care analyst David Williamson discusses Eli Lilly's (LLY 1.19%) recent purchase of two imaging tracers from German conglomerate Siemens. The big pharma currently has Amyvid approved, which detects amyloid brain plaques. Like Amyvid, Eli Lilly is hoping that these tau tangle diagnostics will help both with detection and potentially serve as markers for treatment. Watch and find out how the treatment for Alzheimer's disease is evolving and some potentially groundbreaking drugs in the pipeline.
