Transcript of ADHD

ADHD is the most commonly studied and diagnosed neurological development disorder.
It is predominatly a childhood disorder that carries over into adulthood.
According to DSM-V, there are 3 subgroups in ADHD classification.
Introduction
13
boys taken in for experiment around 12 to 13 years old that are diagnosed with ADHD by a psychiatrist
Oxygen level for the experiment is
21%
and other half is with
92
%
each run consisted of
3
phases at a total of
5
min
Methods
Method
* "The accuracy rate and response time in 2-back task was calculated for the two different Oxygen concentration conditions (21%and 92%).
* Administration made the response time decreased, SPO2 increased, and HR decreased. the response time of the ADHD children with higher SPO2 was reduced during the 2-back stack phase, showing a negative correlation with SPO2. "

Published in 2012


Clinical research was performed by the Department of Brain and Cognitive Engineering at Korea University in Seoul, South Korea.

Researchers studied the effects that increasing the body's oxygen content had on adolecents with Predominantly Inattentive ADHD. The study was designed to show how concentrated oxygen levels improved cognitive performance.

conclusion
While doing this experiment they found that with a higher concentraion of oxygen which is known as blood oxygen saturation (SP02). The increase in SPO2 has shown to increase the production of ATP which can imporve cognitive tasks and improved information processing.


Subgroups
Predominantly Inattentive Presentation:
It's hard for the individual to organize or finish a task, to pay attention to details, or to follow instructions and conversations. (Previously know as ADD)
Predominantly Hyperactive-Impulsive Presentation:

The individual fidgets and talks a lot. It is hard to sit still for long periods. These individuals feel restless, impulsive , and may interrupt others frequently. It is hard for these individuals to wait their turn or listen to directions.
Combined Presentation:
Symptoms of both manifestations are equally present in the individual.

2-Back testing is commonly used in the clinical dignosis of ADHD. It involves a subject viewing a series of numbers or letters and having to respond to elements that occured 2 series prior, or "2-back".

The subject's response time is then measured in milliseconds (ms) and compared to the national average for the subjects age group.

Accoding to Conners Continuous Performance Test (CPT), response time increases with increased distraction for ADHD subjects.
Clinical Testing
The group of children that were exposed to the higher concentration of oxygen showed better and shorter response times, which in other words a positive correlation between SPO2 and the performance in cognitive tasks. with So far it is not known what % of oxygen concentration is needed for optimal imporvements so more testing is needed.
But with these results it provides that the supply of high oxygen concentration can improve cognitive performance in children with ADHD
