Public health agencies around the world have spoken out about the dangers of energy drinks and alcohol on human brains, especially underdeveloped brains. Now, a new study published in PLOS ONE has shown that mixing the two can alter adolescent minds, and cause young mice to show the same kinds of addictive behaviors as if they'd been given hard drugs.
When researchers administered high levels of caffeine mixed with alcohol to adolescent mice, they showed physical and neurochemical signs similar to mice that had ingested cocaine, according to a press release.
"It seems the two substances together push them over a limit that causes changes in their behavior and changes the neurochemistry in their brains," researcher Richard van Rijn said in the press release from Purdue University. "We're clearly seeing effects of the combined drinks that we would not see if drinking one or the other."
Testing the effects of alcohol on human adolescents is illegal, so researchers examined the reactions of mice. The team exposed them to caffeinated alcohol during adolescence and wanted to see if these mice would later consume higher amounts of an artificial sweetener called saccharine. According to Purdue, this substance is similarly pleasurable.
The results of this study reflect what researchers expected — adolescent mice exposed to caffeine and alcohol drank significantly more saccharine than those only exposed to water and they also became significantly more active. This suggests that the exposed mice experienced a chemical change in the brain, authors noted.
"Mice that had been exposed to alcohol and caffeine were somewhat numb to the rewarding effects of cocaine as adults," van Rijn said. "Mice that were exposed to highly caffeinated alcoholic drinks later found cocaine wasn't as pleasurable. They may then use more cocaine to get the same effect."
Moving forward, Van Rijn plans to study the reactions of adolescent brains to legal, but potentially harmful, psychostimulatory substances, such as ethylphenidate.

The study also revealed that individuals who quit smoking, regardless of age, can achieve a life expectancy similar to non-smokers within approximately 10 years after quitting, and nearly half of this benefit can be noticed within just three years.
Researchers found that a combination of genetics and environmental factors reduces longevity in dementia patients. The same combination may shorten the lives of their siblings even without dementia.
The suicide rates increase substantially when air pollution rises, and the effect was particularly strong in the elderly, with older women 2.5 times more at risk than other groups.
While mental stress is commonly acknowledged in connection with grief, it is crucial to understand that grief can also present physical symptoms, including illnesses, fatigue, pain, and sleep disturbances.
The use of antidepressants, particularly fluoxetine, could affect the development of the prefrontal cortex of the infant's brain, potentially raising the risk of mental health disorders later in their life.
Researchers have developed smart earrings that could continuously monitor a person's earlobe temperature. The innovation known as Thermal Earring could also be potentially used to track signs of ovulation, stress, eating, and exercise.
The researchers made the interesting finding using a trial involving patients with a rare genetic condition called Alpha-1 antitrypsin deficiency (AATD).
People infected with the flu were more likely to need hospital care in the following year for common neurologic conditions than people who had the SARS-CoV2 infection.
Among women with a history of pregnancy complications, those who achieved or maintained high heart health after pregnancy were at a similar risk for heart disease as women without adverse pregnancy outcomes and good cardiovascular health, the study stated.
The study published in the journal BMJ indicated that individuals with hypermobile joints had a 30% higher chance of not fully recovering from COVID-19 and experiencing persistent fatigue associated with long COVID.
The studies showed that COVID antigens lingered in the blood up to 14 months after infection and more than two years in tissue samples of people who had the infection.
Those individuals who receive a COVID-19 vaccine during the first half of their menstrual cycle are more likely to experience cycle length changes than those receiving a vaccine in the latter half.
