Science and ADHD — ADHD Tip O the Day 928

If you know all about the bell shaped curve, please scroll down to ADHD and the Curve.

Many phenomena and most human attributes follow a bell shaped curve distribution. Height, for example. If you have a room of a hundred people, line them up by height; there will be a few very short ones and a few very tall, most in between. If you draw a graph of height versus number of people of that height, you get a bell shaped curve.

Bell Shaped Curve

number of people on left, Y axis. Height on bottom, X axis

This does not fit for discrete features, like eye color for example.

ADHD and the Curve:

One of the ADHD controversies is whether ADHD is part of a spectrum, for example, some people have very good attention and some have very poor and most are in the middle and we ADHDers on on the left –

The Spectrum Theory

Or, whether we are not on the curve, but have a discrete condition. This is what I believe.

The Discrete Condition Theory

More Science: Treatment:

80 percent of ADHDers will respond to either methylphenidate or amphetamine, maybe 5 percent will only respond to one of these and maybe 15 percent will not respond to either. And there’s a small percent that can’t tolerate the meds.

If the child is under six, start with a behavioral program. If six or older, behavioral program plus medication. The progam includes parent training and school intervention.


The ADHD Controversy

Dr. Barkley on ADHD in Adults – i don’t agree with all of his points, but it’s a good discussion.

treatment recommendations

Jokes O the Day:

  1. An ADHDer walk into a bar.

Of course.

2. A dyslexic walks into a rab.

Personal Note O the Day:

My plan is to do a broad survey of science, maybe in intermittent posts. That’s my plan anyway. (But remember that I have ADHD.)

Any thoughts about this?

About doug with ADHD

I am a psychiatric physician. I learned I have ADHD at age 64, and then wrote two ADHD books for adults, focusing on strategies for making your life better. I just published my first novel, Alma Means Soul. Your Life Can Be Better; strategies for adults with ADD/ADHD available at, or (for e books) Living Daily With Adult ADD or ADHD: 365 Tips O the Day ( e-book). This is one tip at a time, one page at a time, at your own pace. It's meant to last a year. As a child, I was a bully. Then there was a transformation. Now I am committed to helping people instead abusing them. The Bully was published in January, 2016. It's in print or e book, on Amazon.

    Good post. My opinion: ADHD is a discrete condition that has it’s own bell curve. Even within ADHDers there are those of us with more severe symptoms than others.
    The bell curve, while a great concept, is one of those things that people, who don’t know statistic and complain they never needed that math and algebra stuff outside the classroom; it’s what those people like to use to sound smart, from my personal experience. I do remeber in Biology class, when we learned about the bell curve, that there were several possible graphs for a bell curve – some of them very simillar to the one you drew with the smaller bell-curve on the side. 😉
