ADHD manifests itself in a variety of forms that scientists have yet to fully explain

If you have problems concentrating, are uncomfortable or restless, find yourself misplaced, and continue to be distracted, you may want to know why.For children and adults with attention deficit hyperactivity disorder, or ADHD, These are just a few of the symptoms they may face.

Scientists are now digging deeper into ADHD, looking for neurobiological markers in the brain that can explain how developmental disorders occur. Often misunderstoodAffects people’s behavior, emotions and concentration.

In recent years, imaging research has revealed Differences in the size of certain parts of the brain associated with ADHD.. Researchers believe that disruption of connections in the brain may be another neurological symptomatology of the disorder.

“Growth of evidence from [brain imaging] Studies may help better reconcept ADHD by linking brain-based functioning with improved clinical care models and treatment outcomes. ” writing Psychologist Jacqueline Saad and his colleagues wrote in a new treatise, Release To PLOS One..

This latest study, which examined the white matter part of the brain, did not observe any structural differences associated with ADHD. This is not a setback, as the findings represent a sustained effort by researchers to recognize and understand the brain characteristics that underpin ADHD.

ADHD Is a common but complex neurobehavioral disorder that manifests itself as a pattern of attentionless, impulsive, and sometimes hyperactive behavior.Affect Millions of children And adults all over the world.

Currently being diagnosed alone Based on signs of action, Must be present for at least 6 months.Behavior is generally Dismissal As inadequate self-control or lack of discipline.

The exact cause of ADHD remains unknown, but neuroscientists have shown in some studies that ADHD is due to underlying neurological differences.

If you don’t understand these differences, you run the risk of blaming ADHD for bad behavior. Instead of admitting what it is: Another form of neurodiversity in which people’s brains appear to be wired to function differently.

Previous survey from 2017 The brain differences associated with ADHD were small, but were found to be clearly apparent between about 1,700 children with ADHD and 1,500 adults and 1,500 without ADHD. This is the largest dataset at the time.

2018, Another brain imaging study We found evidence that structural changes associated with ADHD symptoms were recognizable in 4-year-old children with less gray matter in areas related to activity and attention than their peers.

However, distinguishing between different subtypes of ADHD with brain scans seems to be more difficult as it is the purpose of this latest study. This may have something to do with the way ADHD is presented from person to person and over time.

“We need a more sophisticated but clinically relevant model that recognizes the consequences of ADHD from a combination of interaction defects that cause a variety of symptoms in everyone who experiences ADHD,” said a child with a disability. Alison Paulton, an Australian pediatrician who specializes in treating our patients, I have written In 2017. (Paulton was not involved in this new study.)

People with inadvertent ADHD, one of the three subtypes of disability, often struggle to focus on their work, make inadvertent mistakes, and are prone to distractions.

ADHD is also combined and people tend to show symptoms of both attention deficit and hyperactivity impulsivity.

In this new study, researchers examined brain scans from 35 children and teens with ADHD (careless or complex ADHD) and compared them to 28 so-called neural controls.

Using state-of-the-art spatial analysis and 3D modeling technology TractographyResearchers looked at the white matter ultrastructure and network connections in the brain to see the difference between what was certainly a small group of children.

At the structural level, researchers cannot observe the fundamental differences in white matter that distinguish subtypes combined with attentionless subtypes from each other or separate children with ADHD from unaffected controls. was.

These results are consistent with some previous studies, researchers writeOnly a handful of studies are looking for differences in white matter structure between ADHD subtypes, but more studies are needed.

“While this study focused on whether hard-wired networks can provide insights that distinguish subtypes, further studies of functional dynamics of brain network tissues can be found in the neurobiology underlying ADHD subtypes. May provide greater insight into writing..

Behavioral expressions in people with ADHD can also change from time to time from teenage to adulthood, and the ADHD subtype is a rather temporary classification.

“This is probably another potential reason for null findings, as the presentation types of ADHD are not stable over time and therefore may be better associated with functional measurements.” , Saad and colleagues’ brain activity Conclusion..

Some ADHD researchers also insist there to add to the already complex puzzles Can be as many as 7 types of ADHD..

Therefore, it seems that there is still a long way to go to truly understand how ADHD is wired in the brain, but all this form of neurodiversity needs to be understood in the same way.

The study was published in PLOS One..
