Auditory processing disorder in relation to developmental disorders of language, communication and attention: a review and critique - International Journal of Language & Communication Disorders.

This article describes the vagaries of diagnosis of auditory processing issues and shows how important work is being done to help make proper evaluations and treatment research widely available. It is not definitive but is a useful article for those orienting themselves to CAPD issues.
Background: Auditory Processing Disorder (APD) does not feature in mainstream diagnostic classifications such as the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV), but is frequently diagnosed in the United States, Australia and New Zealand, and is becoming more frequently diagnosed in the United Kingdom.

Aims: To familiarize readers with current controversies surrounding APD, with an emphasis on how APD might be conceptualized in relation to language and reading problems, attentional problems and autistic spectrum disorders.
Methods & Procedures: Different conceptual and diagnostic approaches adopted by audiologists and psychologists can lead to a confusing picture whereby the child who is regarded as having a specific learning disability by one group of experts may be given an APD diagnosis by another. While this could be indicative of co-morbidity, there are concerns that different professional groups are using different labels for the same symptoms.
Conclusions & Implications: APD, as currently diagnosed, is not a coherent category, but that rather than abandoning the construct, we need to develop improved methods for assessment and diagnosis, with a focus on interdisciplinary evaluation.

Use It or Lose It: The Theory and Practice of Brain Exercise and Fitness for Cognitive Health - 1252th Edition | Health Blog.

When we exercise our brains, we put our Neurons and connections between neurons in action.



Given the diversity of functions outlined above, it is clear that different activities are going to activate different brain areas, which scientists now know thanks to neuroimaging techniques. There is no one magic bullet that is best (either crosswords puzzles, or computer-based programs, or physical exercise): we do need a variety of mental stimulation or “brain exercises”.

SPD is a difficult topic/diagnosis for people to get their heads around; parents, teachers, scientists, therapists...lots of people. But the awareness is growing that SPD it is a unique neurological disorder that impacts many people in important cognitive areas. Addressing SPD is an important part of any treatment program for those on the spectrum

A newly published article by the Department of Neurology, Division of Cognitive Neuroscience at Johns Hopkins University School of Medicine outlines another look into the role the cerebellum plays in language development and cognition. There are many researchers investigating this part of the brain that is so deeply involved in movement and a huge variety of "automated" functions. The exact logic of how the brain uses all its various systems to divide and tackle the complex cognitive tasks it performs every day is still in its infancy. However, the efficiency of cerebellar functions and how it can be enhanced through calibrated neuro-motor and vestibular training is constantly being examined as a likely method of improving brain fitness generally and as a way to overcome specific learning challenges.

The entire article is available here: Functional Topography of the Cerebellum in Verbal Working Memory, with the abstract printed below for your convenience.

Abstract :

Speech—both overt and covert—facilitates working memory by creating and refreshing motor memory traces, allowing new information to be received and processed. Neuroimaging studies suggest a functional topography within the sub-regions of the cerebellum that subserve verbal working memory. Medial regions of the anterior cerebellum support overt speech, consistent with other forms of motor execution such as finger tapping, whereas lateral portions of the superior cerebellum support speech planning and preparation (e.g., covert speech). The inferior cerebellum is active when information is maintained across a delay, but activation appears to be independent of speech, lateralized by modality of stimulus presentation, and possibly related to phonological storage processes. Motor (dorsal) and cognitive (ventral) channels of cerebellar output nuclei can be distinguished in working memory. Clinical investigations suggest that hyper-activity of cerebellum and disrupted control of inner speech may contribute to certain psychiatric symptoms.

in ADD/ADHD

If you’re the parent of a child who’s having trouble learning or behaving in school, you quickly find yourself confronted with a series of difficult choices.

You can do nothing — and watch your child flounder while teachers register their disapproval. Or you can get help, which generally means, first, an expensive and time-consuming evaluation, then more visits with more specialists, intensive tutoring, therapies, perhaps, or, as is often the case with attention issues, drugs.

For many parents — particularly the sorts of parents who are skeptical of mainstream medicine and of the intentions of what one mother once described to me as “the learning-disability industrial complex” — this experience is an exercise in frustration and alienation.




The rest of the article describes some areas of similarity with LBP because of the program's substantial amount of vision-related activities. The balance and vestibular issues so critical to LBP are not described, but the hurdles that parents face and the ways that treatments are presented to parents, the pressures, etc. will be very strongly identified with by those who have had to walk that road.

From the upcoming release of A Life In Balance: Discovery of a Learning Breakthrough


The Still-Missing Core


"One of the basic principles of a two-engine airplane is the synchronicity between the two engine systems that are fixed on either side of the plane. If one engine puts out more thrust than the other, it causes problems in flight. If the disparity is sufficiently severe, it can cause the plane to go out of control and crash. Remembering this principle caused an idea to begin to percolate: was the issue these children were experiencing related to the balance between the two sides of their bodies?"



"In the mid-1960s, It was not a popular idea to look for learning ability in the body, but the more I observed the children in my classroom, the more the two problems seemed corollary. And why shouldn’t they be? The movement of the body through space is defined by brain functions, just as the ability to read and do arithmetic are defined by brain functions. If the knee bone’s connected to the thigh bone, wouldn’t it make sense that the various departments in the brain are connected, too? I began to wonder: what if an individual’s body provides a graphic representation of the inner workings of the brain?"

MS Comment: There are so many background insights in this book relating to "basic operating principles" and basic common sense that sensory integration, vestibular remediation and somatosensory become actually exciting to study. A more profound model of human cognition than you would ever expect upon initial reflection.
