London, February 3, 2017: Ever wondered why the sound of people chewing food, breathing off, a pen clicking repeatedly cause irritation? It may be because of an abnormality in the emotional control mechanism which causes the brain to go into overdrive on hearing such trigger sounds, say researchers led by one of Indian-origin.

The findings showed that the brains of people with such condition — known as misophonia or hatred of trigger sounds — showed a physical difference in the frontal lobe between the cerebral hemispheres — with higher myelination in the grey matter of ventromedial prefrontal cortex (vmPFC).

“For many people with misophonia…for the first time we have demonstrated a difference in brain structure and function in sufferers,” said Sukhbinder Kumar at Newcastle University in Britain.

Further, the study, published in the journal Current Biology, also showed abnormal connections between this frontal-lobe area and an area called the anterior insular cortex (AIC) — known to be involved in processing emotions and integrating signals both from the body and outside world.

In misophonic participants, the trigger sounds increased activity in both brain areas, while in normal participants, the increase was seen only in the AIC, not in the frontal area.

This reflects an abnormality of a control mechanism between the frontal lobe and AIC, the researchers said.

“We now have evidence to establish the basis for the disorder through the differences in brain control mechanism in misophonia. This will suggest therapeutic manipulations and encourage a search for similar mechanisms in other conditions associated with abnormal emotional reactions,” added Tim Griffiths, professor at Newcastle University.

The trigger sound was also found to evoke a heightened physiological response with increased heart rate and sweating in people with misophonia, the researchers noted. (IANS)

ADHD May Be Improved With Support And Self Regulation: Study

While research shows that medication is effective, it does not work for all children, and is not acceptable to some families.

One-to-one support and a focus on self-regulation may improve academic outcomes of children with Attention Deficit Hyperactivity Disorder (ADHD), a new study suggests.

ADHD refers to a chronic condition including attention difficulty, hyperactivity and impulsiveness.

“Children with ADHD are of course all unique. It’s a complex issue and there is no one-size-fits-all approach,” said Tamsin Ford, Professor from the the University of Exeter in the UK.

The results indicate that children with ADHD who received canine assisted intervention (CAI) experienced a reduction in inattention and an improvement in social skills. Pixabay

“However, our research gives the strongest evidence to date that non-drug interventions in schools can support children to meet their potential in terms of academic and other outcomes,” said Ford.

For the study, published in the journal Review of Education, the team found 28 randomised control trials on non-drug measures to support children with ADHD in schools.

They found that important aspects of successful interventions for improving the academic outcomes of children are when they focus on self-regulation and are delivered in one-to-one sessions.

According to the study, self-regulation is hard for children who are very impulsive and struggle to focus attention.

While research shows that medication is effective, it does not work for all children, and is not acceptable to some families.

“More and better quality research is needed but in the mean-time, schools should try daily report cards and to increase children’s ability to regulate their emotions. These approaches may work best for children with ADHD by one-to-one delivery,” Ford noted. (IANS)
