Abuse of opiates such as heroin, methadone and morphine destroy brain cells, reducing attention span and memory. But new research shows there may be a way to regain some lost patience and recall.

Researchers from Uppsala University in Sweden report in Proceedings of the National Academy of Sciences USA that brain cells targeted for early death by continued opiate use may be salvaged by injections of synthetic human growth hormone (HGH). HGH is a chemical naturally secreted by the pituitary gland at the base of the brain that stimulates cell growth and reproduction. The scientists say their findings open the door to new ways to treat and prevent damage from abuse of opiates in addicts as well as patients undergoing chronic pain management.
