The colour of our hair or the shape of our eyes is linked to our DNA, but the development of Alzheimer’s disease isn’t exclusively linked to genetics, suggest recently published findings[1]. In the first study published about Alzheimer’s disease among identical triplets, researchers found that despite sharing the same DNA, two of the triplets developed… Read more

When a pregnant woman consumes a diet high in polyunsaturated omega-6 fatty acids, her body produces an excess of endogenous cannabinoids (endocannabinoids), which overload the fetal system and impair the development of healthy brain networks, Medical University of Vienna researchers report. Such a mechanism seems relevant to pathologies such as ADHD, schizophrenia and anxiety disorders… Read more

A possible role of the hormone oxytocin in men and women with hypersexual disorder has been revealed in a new study[1]. The finding could potentially open the door to treating the disorder by engineering a way to suppress its activity. Hypersexual disorder, also referred to as sexual addiction[2], or an overactive sex drive, is recognized… Read more

The neurotransmitter serotonin, known for its role in passing signals between neurons in the brain, is also able to regulate expression of genes within neurons in an unexpected way, according to new research conducted by neuroscientists at the Icahn School of Medicine at Mount Sinai. The discovery may help scientists better understand a range of… Read more

Binge and heavy drinking may trigger a long-lasting genetic change, resulting in an even greater craving for alcohol, according to a new study. “We found that people who drink heavily may be changing their DNA in a way that makes them crave alcohol even more. This may help explain why alcoholism is such a powerful… Read more
