The new work examines the idea that methamphetamine puts young users at risk of developing deficits later in life that are symptomatic of Parkinson's disease in individuals with depletion of glial derived neurotrophic factor, a protein that protects and repairs dopamine in areas of the brain related to movement control. Loss of nerve cells that produce dopamine is a major factor in the disease.
