Bacteria in The Gut May Lead to Anxiety, Depression

The researchers are now working to identify specific populations of bacteria involved in these processes and the molecules that the bacteria produce

Gut bacteria plays a key role in infusing negative feelings in the brains of obese people, causing depression and anxiety, researchers say.

The findings showed that mice on a high-fat diet showed significantly more signs of anxiety, depression and obsessive behaviour than animals on standard diets.

In mice with high-fat diets, two areas of the brain, the hypothalamus, which helps to control whole body metabolism, and the nucleus accumbens, important in mood and behaviour, becomes insulin resistant.

“Your diet isn’t always necessarily just making your blood sugar higher or lower; it’s also changing a lot of signals coming from gut microbes and these signals make it all the way to the brain,” said C. Ronald Kahn, from the Joslin Diabetes Centre in the US.

“But all of these behaviours are reversed or improved when antibiotics that will change the gut microbiome were given with the high fat diet,” Kahn added.

In the study, published in the journal Molecular Psychiatry, the team identified the effect of the microbiome by transferring gut bacteria from experimental mice to germ-free mice which did not have any bacteria of their own.

The animals which received bacteria from mice on a high-fat diet began to show increased levels of activity associated with anxiety and obsessive behaviour.

However, those who got microbes from mice on a high-fat diet plus antibiotics did not, even though they did not receive the antibiotics themselves.

“If we could modify those bacteria, either by putting in more beneficial bacteria or reducing the number of harmful bacteria, that might be a way to see improved behaviour,” Kahn noted. (IANS)

40% Parents Struggle to see Depression Signs in Kids: Study

Most parents also believe schools should play a role in identifying potential depression, with seven in 10 supporting depression screening starting in middle school, the study said

Telling the difference between a teen’s normal ups and downs or something bigger is among the top challenges parents face while identifying depression among the youth, says a new study.

Forty per cent of parents struggle to differentiate between normal mood swings and signs of depression, while 30 per cent are tricked as their child hides his/her feelings well, according to a new national poll in the US.

The C.S. Mott Children’s Hospital National Poll on Children’s Health at the University of Michigan, is based on responses from 819 parents with at least one child in middle school, junior high, or high school.

“In many families, the preteen and teen years bring dramatic changes both in youth behaviour and in the dynamic between parents and children,” said poll co-director Sarah Clark.

“These transitions can make it particularly challenging to get a read on children’s emotional state and whether there is possible depression,” Clark added.

According to the researchers, some parents might be overestimating their ability to recognise depression in the mood and behaviour of their own child.

An overconfident parent may fail to pick up on the subtle signals that something is amiss.

The poll also suggests that the topic of depression is all too familiar for middle and high school students.

One in four parents say their child knows a peer or classmate with depression, and one in 10 say their child knows a peer or classmate who has died by suicide.

This level of familiarity with depression and suicide is consistent with recent statistics showing a dramatic increase in suicide among US youth over the past decade.

Rising rates of suicide highlight the importance of recognising depression in youth.

Compared to the ratings of their own ability, parents polled were also less confident that their preteens or teens would recognise depression in themselves.

“Parents should stay vigilant on spotting any signs of potential depression in kids, which may vary from sadness and isolation to anger, irritability and acting out,” said Clark.
