Young adults who had been maltreated as children differed from others who had not been maltreated in the connectivity of nine cortical regions. The differences could compromise the maltreated group’s basic social perceptual skills, ability to maintain a healthy balance between introversion and extroversion, and ability to self-regulate their emotions and behavior.

NIDA redesigns Easy to Read and Learn the Link websites for mobile devices

Two researchers share their reasons for researching transcranial magnetic stimulation (TMS) for treating cocaine addiction, and describe challenges to moving forward this potentially promising therapy.

In mice, a cocaine-induced imbalance in the activity of two key populations of neurons in the reward system persists for a longer period after repeated exposure to the drug. For long-term users, this change could both weaken the cocaine “high” and strengthen the compulsion to seek the drug.

Grant Awards Mark the Launch of Landmark Adolescent Brain Cognitive Development (ABCD) Study

The teen years are the period of highest risk for substance use and for the development of other behavioral disorders, and they are also a period when the brain is changing dramatically. A study of this scope will yield an unprecedented amount of detailed information.

NIH launches landmark study on substance use and adolescent brain development

The Adolescent Brain Cognitive Development (ABCD) Study will follow approximately 10,000 children beginning at ages 9 to10, before they initiate drug use, through the period of highest risk for substance use and other mental health disorders.

Adolescent monkeys that were exposed to THC fell progressively further behind THC-free monkeys in their ability to recall the location of an object after a brief delay.

A NIDA-supported study has found that a cocaine-addicted person’s chance of managing 1 whole year of abstinence correlates with activity levels in these impaired motivational and decision-making brain areas.

Addiction Science Can Help Us Understand the Bee Crisis

Recent research now suggests that bees may be preferentially drawn to foods laced with pesticides as a result of reward mechanisms. It is a fascinating lesson in how knowledge gleaned from one area of science—in this case addiction science—can inform our understanding of a global ecological crisis.

NIDA and NIAAA commentary strongly supports brain disease model of addiction

These findings, along with ongoing research, are helping to explain how drugs and alcohol affect brain processes associated with loss of control, compulsive drug taking, inflexible behavior, and negative emotional states associated with addiction.
