Health Watch -- The Nervous System: Cocaine Addiction
Health Watch is a Public Service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.
This week on Health Watch, we’re talking about the brain and nervous system. We know that cocaine is a dangerous drug, but researchers at UT Southwestern Medical Center at Dallas have discovered how it affects the brain to produce the immediate high from cocaine use and to develop an addiction on a long-term basis.
The researchers found that cocaine alters the biochemical processes in the brain, allowing certain genes to be turned on in the brain’s reward centers to produce the cocaine high and different genes to be affected in long-term use to create addiction. Dr. Eric Nestler, UT Southwestern’s chairman of psychiatry, says that understanding how cocaine affects the brain at the molecular level may lead to new treatments for addiction.
Health Watch is heard Monday through Friday nationwide on ABC Satellite Radio. Call your local radio station and ask if they carry the program.
