Drug reduces brain changes, motor deficits of Huntington's disease

A drug that acts like a growth-promoting protein in the brain reduces degeneration and motor deficits associated with Huntington's disease in two mouse models of the disorder, according to a study. The findings add to a growing body of evidence that protecting or boosting neurotrophins -- the molecules that support the survival and function of nerve cells -- may slow the progression of Huntington's disease and other neurodegenerative disorders.
