Description Of ADD vs. ADHD ADD versus ADHD What's the difference?
I came across something interesting tonight while researching.
I found this page:
http://www.ldpride.net/addsub-types.htm
It talks about the difference between ADD, without hyperactivity, and ADHD, which is WITH hyperactivity.
It says that regular ADD, is different than ADHD, in that ADHD is caused by an under-stimulation in the frontal lobe, and ADD is more of a problem of the parietal lobe.
So, this got me thinking...I match most of the descriptions of normal ADD... so I did a Google search for marijuana's effects on the parietal lobe.
I found this page:

If you read it, you'll see this:
Scientists have studied electrical activity in the frontal lobes of the brain in Marijuana users using event-related potential measurements (ERP). [FONT=verdana, arial, helvetica]
You can measure not only patterns of electrical activity in the brain using electrodes placed over the head, but also the speed of brain reactions to - say - a picture or a sound.[/FONT]
[FONT=verdana, arial, helvetica]Research shows that with increased length of use, Marijuana users are less able to focus attention and filter out irrelevant stimuli, (frontal lobe [/FONT][FONT=verdana, arial, helvetica]
activity). However[/FONT][FONT=verdana, arial, helvetica]
with increasing frequency of use there was a growing problem in the parietal area of the brain with slower speed of information processing.[/FONT]
[FONT=verdana, arial, helvetica]Its interesting. AND it makes sense. If ADD people have overactive parietal lobes, then it makes sense, that something that can calm that lobe, like marijuana, would actually help them. In the case of normal people, frequent use would be bad, but for ADD people, frequent use would calm them.[/FONT]
[FONT=verdana, arial, helvetica]So, the next question is, does marijuana help ADHD people, who have problems with their frontal lobes? How much marijuana would these people need? Maybe, the dose of marijuana, that can affectively stimulate the frontal lobes, is higher, than the dose that is needed to calm the parietal lobes.[/FONT]
[FONT=verdana, arial, helvetica]What we really need, is someone to do testing with brain scanning machines. I would be interested to see the effect on the different lobes, with different amounts and strains of marijuana.[/FONT]
that gives an idea of what add is, also what adhd is.. i just copy and pasted what i read.
