    A brain chemical tied to narcolepsy may play a role in opioid addiction

    Using opioids gives some brain cells a call to action.

    Opioid addicts’ brains, examined after death, contain about 50 percent more nerve cells that release a molecule called hypocretin, compared with people who didn’t use the drugs, a new study finds. Giving the opiate morphine to mice also induced similar changes in their brains. But the increase didn’t come from new nerve cells, or...

    Depression among new mothers is finally getting some attention

    On the hormonal roller coaster of life, the ups and downs of childbirth are the Tower of Power. For nine long months, a woman’s body and brain absorb a slow upwelling of hormones, notably progesterone and estrogen. The ovaries and placenta produce these two chemicals in a gradual but relentless rise to support the developing fetus.

    With the birth of a baby, and the immediate expulsion of...

    Sounds and glowing screens impair mouse brains

    SAN DIEGO — Mice raised in cages bombarded with glowing lights and sounds have profound brain abnormalities and behavioral trouble. Hours of daily stimulation led to behaviors reminiscent of attention-deficit/hyperactivity disorder, scientists reported November 14 at the annual meeting of the Society for Neuroscience.

    Certain kinds of sensory stimulation, such as sights and sounds, are...

    Fentanyl’s death toll is rising

    For some people, fentanyl can be a life-saver, easing profound pain. But outside of a doctor’s office, the powerful opioid drug is also a covert killer.

    In the last several years, clandestine drugmakers have begun experimenting with this ingredient, baking it into drugs sold on the streets, most notably heroin. Fentanyl and closely related compounds have “literally invaded the entire...

    Vaccines could counter addictive opioids

    By age 25, Patrick Schnur had cycled through a series of treatment programs, trying different medications to kick his heroin habit. But the drugs posed problems too: Vivitrol injections were painful and created intense heroin cravings as the drug wore off. Suboxone left him drowsy, depressed and unable to study or go running like he wanted to. Determined to resume the life he had before his...

    Cocaine addicts can’t kick other habits either

    People hooked on cocaine are more likely to stick to other habits, too. They’re also less sensitive to negative feedback that tends to push nonaddicts away from harmful habitual behaviors, new research published in the June 17 Science suggests.  

    The findings might help explain why cocaine addicts will do nearly anything to keep using the drug, despite awareness of its negative...

    Caffeine gives cocaine an addictive boost

    Many people perceive cocaine as one of the most intense stimulant drugs available: It’s illegal, highly addictive and dangerous. Caffeine, in contrast, is the kinder, cuddlier stimulant. It’s legal, has mild effects and in forms such as coffee, it might even be good for your health.

    But caffeine in combination with cocaine is another story. In South America, drug distributors have...

    No, cheese is not just like crack

    Cheese is a delicious invention. But if you saw the news last week, you might think it’s on its way to being classified as a Schedule II drug. Headlines proclaimed “Say cheese? All the time? Maybe you have an addiction,” “Cheese really is crack” and “Your cheese addiction is real.”  Under the headlines, the stories referred to a study examining the addictive properties of various foods. Pizza...

    Adolescent brains open to change

    Under the carefully styled hair of a teenager, the brain is roiling with change. Some nerve cells are killed off, others are pruned back and still others are locked into place, a restyling that moves the brain closer to its adult form. This dramatic adolescent makeover represents a window of opportunity known as a sensitive period, allowing the brain to be selectively shaped by the outside...
