Heroin Addiction Warps Brain’s Ability to Change

brain“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, of the Icahn School of Medicine at Mount Sinai Hospital in New York, N.Y., 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 over activity may help temper addiction, Hurd told MedPage Today during an oral presentation at the Society for Neuroscience meeting.”
