Alexander disease is a progressive and rare neurological disorder with no cure or standard course of treatment. But a new study led by researchers at the University of Wisconsin–Madison involving a rat model of the disease offers a potential treatment for the typically fatal condition.
It’s a significant step in efforts to help people with the disease, says UW–Madison Waisman Center senior scientist Tracy Hagemann, who led the study alongside Albee Messing, professor emeritus of comparative biosciences and founder of the Alexander Disease Lab. With University of Alabama at Birmingham colleague Michael Brenner, Messing discovered the gene responsible for Alexander disease more than 20 years ago.
People born with Alexander disease may develop an enlarged brain and head, experience seizures or delayed development, have stiffness in their arms and legs, and have intellectual disabilities. The disease, which involves destruction of the white matter of the brain, is often not diagnosed until symptoms are pronounced, says Hagemann. Read more …
