Nourishing protein slows brain disease

A protein that promotes neuron growth and blood vessel formation appears to halt brain degeneration in a genetic disease, according to Northwestern University research published in Nature Medicine. The study suggests a link between aging and the development of spinocerebellar ataxia type 1, a disease causing cerebellum degeneration.
