The research, published in CMAJ Open, showed that more than one in four adults reported exposure to physical abuse and one in five reported exposure to intimate partner violence and emotional abuse in childhood.

Eating to much sugar can lead to microbiome. Pixabay

Eating too much fat and sugar as a child can alter your microbiome for life, even if you later learn to eat healthier, a new study suggests. The microbiome refers to all the bacteria as well as fungi, parasites, and viruses that live on and inside a human or animal.

Most of these micro-organisms are found in the intestines, and most of them are helpful, stimulating the immune system, breaking down food, and helping synthesize key vitamins, the researchers said in the mice-based study.

The study indicates that greater exposure to air pollution at the very start of life was associated with a detrimental effect on people’s cognitive skills up to 60 years later.

“For the first time we have shown the effect that exposure to air pollution very early in life could have on the brain many decades later,” said co-author Tom Russ from the University of Edinburgh.

Childhood trauma could affect the trajectory of multiple sclerosis development and response to treatment in adulthood, a new study suggests. Multiple sclerosis is a progressive autoimmune disease in which the body attacks and strips away the protective coating around neurons, resulting in a wide range of neurological symptoms.

In a mice-based study, researchers found that mice that had experienced stress when young were more likely to develop the autoimmune disorder and less likely to respond to a common treatment.
