The 2/3rds rule has been around for a good while, but its good theres some supporting scientific evidence.
A 70% chance of ADHD being inherited I believe is a substantial percentage change. I dont recall that the % of expectation has been that high in my prior readings particularly considering just one parent, e.g., What's clear, though, is that ADHD is highly heritable if one parent has or had the condition, their child has about a 70% chance of inheriting it.
I first misread, Though most people outgrow the hyperactivity aspect characterized by having trouble sitting still, moving around when others are seated, or talking while others are talking about a quarter to a third of children and teenagers carry their ADHD into adulthood. I interpreted it as all ADHD symptoms, and kind of dismissed the study blew right through the hyperactivity aspect notation. lol Glad I reread it.
The CNN article states, Dr. Louis J. Kraus, chief of child psychiatry at Rush University Medical Center in Chicago, Illinois, said "what is really important about this study is it shows us there is clearly something biologically driven for children with ADHD." Id like to package it and sent it to all the ignorant people that believe ADHD does not exist.
Delayed in the ADHD children was development of the higher-order functions and areas which coordinate those with the motor areas. And, Slowest to mature in ADHD children were parts of the front and side of the brain that integrate information from the sensory areas with the higher-order functions. One area lagged five years in those with the disorder. More scientific support regarding executive function, motor skill, and sensory issue problems experienced by our ADHD kids?
It is important that parents don't immediately jump out and want to get some type of MRI of their child's brain, or functional study to support a diagnosis," Kraus added in a telephone interview.
Shaw agreed: "Brain imaging is still not ready for use as a diagnostic tool in ADHD. Although the delay in cortex development was marked, it could only be detected when a very large number of children with the disorder were included. It is not yet possible to detect such delay from the brain scans of just one individual. The diagnosis of ADHD remains clinical, based on taking a history from the child, the family and teachers."
Hope they develop this technique very soon. Can you imagine the time and money that could be saved in getting a timely diagnosis and early interventions?
Thanks ladies.
