Squirming Helps Kids With ADHD Learn, Study Finds

Study overturns long-held belief about how to treat kids with ADHD.

Study overturns long-held belief about how to treat kids with ADHD.

Excessive movement helps the learning of children with Attention-Deficit Hyperactivity Disorder (ADHD), a new study finds.

Kids with ADHD often tap their feet, swing their legs and generally move around a lot.

This has often been considered behaviour that needs to be curbed.

New research finds, though, that excessive movement is key to their memory and helps them work on difficult cognitive tasks.

This suggests that traditional approaches to ADHD may be misguided.

Professor Mark Rapport, head of the Children’s Learning Clinic at the University of Central Florida, and one of the study’s authors, said:

“The typical interventions target reducing hyperactivity.

It’s exactly the opposite of what we should be doing for a majority of children with ADHD.

The message isn’t ‘Let them run around the room,’ but you need to be able to facilitate their movement so they can maintain the level of alertness necessary for cognitive activities.”

The study involved 52 boys, 29 of whom were diagnosed with ADHD.

All were asked to perform a series of tasks to check their working memory.

Working memory is vital to how we reason, learn and understand the world.

For example, the children had to sort out a series of letters and numbers.

While they performed the task, the children were observed and taped.

Professor Rapport explained that children with ADHD performed better when they moved around:

“What we’ve found is that when they’re moving the most, the majority of them perform better.

They have to move to maintain alertness.”

In contrast, children without ADHD performed worse when they moved around more.

The results tie in with a previous study finding that the excessive movement of hyperactive children is linked to their thinking.

When they are not thinking hard, they don’t move around so much.

The new study was published in the Journal of Abnormal Child Psychology (Sarver et al., 2015).

The Environmental Factor Linked to Huge Rise in ADHD

Exposure to environmental factor increased children’s chances of developing attention problems by five times.

Exposure to environmental factor increased children’s chances of developing attention problems by five times.

Rising air pollution in urban areas could be linked to the rapid increase in diagnosis in ADHD (Attention Deficit Hyperactivity Disorder), a new study suggests.

The research, published in the journal PLOS ONE, finds that prenatal exposure to polycyclic aromatic hydrocarbons (PAH), a component of air pollution, increases the chances of children developing ADHD by five times (Perera et al., 2014).

ADHD is thought to affect 1 in 10 children and is often characterised by a distracted nature, a propensity to daydream and an inability to concentrate and complete tasks.

The new study followed 233 pregnant women in New York City over 9 years as their children grew up.

The women were all Dominican and African-American, living in and around the South Bronx, Harlem and Washington Heights areas of New York City.

The results showed that greater exposure to PAH was associated with symptoms of ADHD as the children got older.

PAH is mostly produced by the burning of fossil fuels: so it comes from many sources, including traffic, domestic boilers and some power stations.

Dr. Frederica Perera, the study’s lead author, said:

“This study suggests that exposure to PAH encountered in New York City air may play a role in childhood ADHD.

The findings are concerning because attention problems are known to impact school performance, social relationships, and occupational performance.”

It’s not yet known exactly what the link is between PAH and ADHD, although it may be related to DNA damage or disruption of the endocrine system.

This study is not the first to suggest a link between pollution and mental health problems.

Previous studies by The Centers for Disease Control have found that PAH exposure may cause lower IQ, increased anxiety and depression and even developmental delays.

This is the first study, though, to find a link between air pollution and ADHD.

ADHD and Working Memory: Computer Training Shows Benefit

RitalinA recent study reported in Scientific American points the way towards a possible new treatment for ADHD. Attention Deficit Hyperactivity Disorder or ADHD is a widely misunderstood condition which severely affects as many as one in a 100 children.

Many studies have already shown the benefits of medication – specifically Ritalin – in treating the condition. This is a stimulant that can improve ADHD dramatically, although exactly how it works remains a mystery.

One theory is that the problems associated with ADHD are partly a result of an impairment of working memory. This new research examines the possibility that a computer programme can be used to train working memory.

The outcomes from this study showed a significant benefit after training as rated by the children’s parents. To its detriment though, no benefit was seen by the children’s teachers. As ever, with brand new treatment methods, it remains to be seen whether these results can be replicated, and also whether teacher ratings will show an improvement.
