The National Center for Learning Disabilities, a US advocacy group, released a report entitled “The State of Learning Disabilities” today. The report presents broad-strokes data about Learning Disabilities (LD) across the life span, including (for example) data about not only school environments, but also work situations.
Highlights from the report include:
- The identification rate of school-age students with LD has consistently declined for the past 10 years
- Learning disabilities disproportionately affect people living in poverty
- People of all races are identified with LD at about the same rate (except people of Asian descent), and,
- The cost of educating a student with LD is 1.6 times higher than a regular education student (compared with 1.9 for all students with disabilities).

Chiropractors are likely to complain about the treatment that their methods receive in posts on this blog. I’ve posted recently that I find wanting the bases for the the (currently-on-tour, see-’em-in-your-neighborhood-soon) Brain Balance Music program. This post will be even more alarming to supporters of those sorts of treatments for LD.
The fundamental problem with the therapies for Learning Disabilities recommended by some chiropractors is that those therapies are bogus. They may be advocated by people who honestly believe that they’re recommending helpful stuff. The hypothetical relations among the neurological and behavioral factors may sound sensible, but that is, in large part, because we’re listening to the words rather than the facts. The folks may have seen what they believe are legitimate improvements in children’s academic and social behavior after the children received the therapy. Parents may have told them how much better the children seem.
None of that counts as scientific (i.e., objective, generalizable, refutable) evidence of benefits. The advocates may be as seriously misled as they mislead their potential clients. They just don’t have the data. Their explanations are post hoc and untested, at best.
In addition to the probably benign Brain Balance Music methods, consider one of the other chiropractic therapies: Cranio-sacral therapy: The hypothesis is that something about the connection between the child’s head and tail causes learning problems (even mental retardation and autism!) and it can be corrected by chiropractic manipulations.

Writing in Pediatrics Richard M. Scheffler and colleagues reported that elementary-aged children who took medication for ADHD had higher mathematics and reading scores than their unmedicated peers with ADHD. The research team identified individuals in the Early Childhood Longitudinal Study—Kindergarten Class data set whose parents repeatedly reported that they had been diagnosed with ADHD and compared the achievement data for those children with ADHD whose parents said their child had taken medication to the achievement of those children with ADHD whose parents said their child had not taken medication. The scores of the children who had taken medication were about two or three tenths of a school year higher than those of the children who had not taken medication.
Although these findings extend the scientific understanding of psychopharmacologic treatment of ADHD, it is important to note that they are essentially correlational, not experimental. Although the study is very well done (uses a good data set, sophisitcated statistical analysis, etc.), the children were not randomly assigned to medication and non-medication conditions. It is possible that (a) some other factors explain why some children were or were not medicated, and that other factor may be the cause of the differences in achievement or (b) that children who had higher achievement were simply less likely to be medicated.
Here’s the abstract:
