Heroin Addiction Warps Brain's Ability to Change - Cole Petrochko

 – November 14, 2013  –– 

In a study of heroin abusers' post-mortem brains, longer duration of heroin use was associated with changes in the shape and packaging of DNA in the brain in the ventral and dorsal striatum, areas of the brain associated with drug addiction, according to Yasmin Hurd, PhD, Professor of Psychiatry, Neuroscience, Pharmacology and System Therapeutics at the Icahn School of Medicine at Mount Sinai and colleagues. “The DNA of these patients' brains became more "open" to gene expression and overactive, which may mean that a treatment that helps "close" this gap and reduce overactivity may help temper addiction,” said Dr. Hurd.
