Examining alcohol use disorders through gene networks instead of individual genes |
|
| |
Multiple genetic, environmental and behavioral factors contribute to alcohol use disorders (AUDs). A person's level of response (LR) to alcohol can indicate a person's risk for developing AUDs. A new study has looked at "gene networks" instead of individual genes to confirm the influence of glutamate receptor signaling genes on a person's LR. |

|
| |
Recent studies have shown that behaviors such as happiness, obesity, smoking and altruism are "contagious" within adult social networks. In other words, your behavior not only influences your friends, but also their friends and so on. Researchers have taken this a step farther and found that the spread of one behavior in social networks influences the spread of another behavior -- adolescent drug use. |

Brain abnormalities identified that result from prenatal methamphetamine exposure |
|
| |
Children whose mothers abused methamphetamine (meth) during pregnancy show brain abnormalities that may be more severe than that of children exposed to alcohol prenatally, according to a new study. While researchers have long known that drug abuse during pregnancy can alter fetal brain development, this finding shows the potential impact of meth. Identifying vulnerable brain structures may help predict particular learning and behavioral problems in meth-exposed children. |
