Workouts at the (New Yorker) brain gym

NewYorkerGood article on brain fitness and applied neuroplasticity in the July 29th edition of The New Yorker, featuring many SharpBrains friends. Mentally fit — Workouts at the brain gym:

"As recently as a few decades ago, most biologists thought that the brain was fully formed during childhood and, like a photograph after it's been developed, was doomed to degrade thereafter, with neurons (nerve cells) fading like pigment on paper until you succumbed to senility. Today, we regard Alzheimer's and other dementias as diseases, rather than as a consequence of normal aging. Moreover, we now consider the brain to be as labile as a digital image in the hands of a Photoshop fiend…Not only does the brain have a lifelong ability to create new neurons; like a government with an unlimited highway budget, it has an endless capacity to build new roadways…The ability of the brain to establish new connections is called plasticity, and brain-fitness exercises are predicated on this mechanism…That's enough science for now. Let's get back to me. . . ."

Focused, unfocused, and defocused information in working memory.
The study investigated the effect of selection cues in working memory (WM) on the fate of not-selected contents of WM. Experiments 1A and 1B showed that focusing on 1 cued item in WM does not impair memory for the remaining items. The nonfocused items are maintained in WM even when this is not required by the task. Experiments 2 and 3 showed that items that were once focused in WM remain strengthened after the focus shifts away from them. When defocused items are presented as mismatching recognition probes, they are rejected better than other mismatching probes (Experiments 2 and 3). When a defocused item was later cued again, such that the focus had to shift back to it, that item was recognized better than an item cued for the first time (Experiment 3). The results support the distinction between mechanisms for temporary maintenance and the focus of attention in WM, and they challenge theories that explain maintenance and focusing by the same mechanisms, such as a limited number of slots or a limited resource.

The Importance of Sensory Integration Therapy [feedly]


 
Shared via feedly // published on Special Education Law Blog // visit site
The Importance of Sensory Integration Therapy

Sensory integration therapy (SIT) has been one of the treatment mainstays for thousands of children diagnosed with autism spectrum disorders, ADD/ADHD, or other developmental disorders. According to the American Occupational Therapy Association (AOTA), approximately 5 to 15% of children in the general population have sensory processing issues.School-based and private occupational therapists and parents have brushed, swung, and bounced on balls countless children in an effort to improve their ability to process sensory input. Yet, the effectiveness of this therapy, despite accolades it has received from therapists and parents, has been questioned. Now a new study by Lang et al that assesses the benefits of SIT by reviewing 25 existing studies adds additional fuel to the debate. In a nutshell, the study authors state that SIT is neither effective nor research-based and that agencies (such as schools) that are mandated to provide research-based interventions should not be using SIT. 

Lang et al culled electronic data bases for different studies that purported to measure the effectiveness of SIT. To be included in the Lang review, the study had to meet certain inclusion criteria; namely, at least one participant had to be diagnosed with an ASD and some form of SIT had to be implemented in an effort to ameliorate the symptoms of the ASD. The SIT was then classified as positive, negative, or mixed depending on its effectiveness. Additionally, the methodological rigor of the study was examined to determine if the study had a true experimental design that among other things could be replicated. 

Of the 25 studies included in the review, 3 suggested that SIT was effective, 8 had mixed results, and 14 showed no improvement related to SIT. The study authors went on to state that many of the studies reviewed, including the three with positive results, had serious methodological flaws. 

Not surprisingly, the AOTA has come back pretty hard denouncing this review by Lang et al. SIT, according to the AOTA, needs to be tailored very specifically to the child and offered for prolonged periods of time. The SIT used in all 14 of the studies that Lang et al rated ineffective was neither performed appropriately nor in the recommended time frame to be effective, according to the AOTA. Additionally, in a number of those studies that had positive or mixed results, the SIT was used more appropriately, according to the AOTA. With regards to study methodology, the AOTA argues that just because a study's methodology is weak does not mean the SIT was ineffective. More rigorous study may be needed, but researchers need to recognize that the lack of homogeneity in children with ASDs and the need to individuate SIT treatments make it very difficult to design controlled studies.

The American Academy of Pediatrics had jumped into this argument last spring in a policy statement on sensory integration therapies, which adopts a more middle of the road approach. According to the AAP, "Occupational therapy with the use of sensory-based therapies may be acceptable as one of the components of a comprehensive treatment plan." However, the AAP suggests that pediatricians need to discuss with parents the limitations of the research involving the effectiveness of SIT and work with families on how to determine if the SIT is working for their child or not. 

Some school districts may perhaps use the Lang study as a justification for removing SIT from their special education programs, since Lang declared it was not research-based, as required by IDEA and NCLB. So, where does this leave children with ASD and other disabilities and their parents? In my experience over the last several years more districts are seeing the benefits of sensory integration, althought the effectiveness of the providers is very broad. Hopefully this study will not move things in the wrong direction. Students need all the tools arrayed in their favor including SIT.

Nebraska football team developing 10-minute concussion test

concussion_capNebraska to study concussions (ESPN):

"…the day is coming when a football player who takes a hit to the head will come to the sideline, take off his helmet and slip on an electrode-covered mesh cap…The team's medical staff will analyze the player's brain waves on the spot and determine within minutes whether he can safely return to the game or whether he has sustained a concussion and, if so, how severe.

"There's no question it's going to move the dial forward," NCAA chief medical officer Brian Hainline said. "The big, hoped-for dream would be, let's have a biomarker in brain imaging. If you're to the left of that, you're safe; if you're to the right of it, you're not. That's probably a few years out. But functional brain imaging and blood flow are going to be a very important part of that."

Reading or watching TV tonight?

booksBeing a Lifelong Bookworm May Keep You Sharp in Old Age (Smithsonian.com):

"…findings, published online today in Neurology, suggest that reading books, writing and engaging in other similar brain-stimulating activities slows down cognitive decline in old age, independent of common age-related neurodegenerative diseases. In particular, people who participated in mentally stimulating activities over their lifetimes, both in young, middle and old age, had a slower rate of decline in memory and other mental capacities than those who did not…

Reading gives our brains a workout because comprehending text requires more mental energy than, for example, processing an image on a television screen."

StudyLife-span cognitive activity, neuropathologic burden, and cognitive aging (Neurology). From the Abstract:

  • Objective: To test the hypothesis that cognitive activity across the life span is related to late-life cognitive decline not linked to common neuropathologic disorders.
  • Methods: On enrollment, older participants in a longitudinal clinical-pathologic cohort study rated late-life (i.e., current) and early-life participation in cognitively stimulating activities. After a mean of 5.8 years of annual cognitive function testing, 294 individuals had died and undergone neuropathologic examination. Chronic gross infarcts, chronic microscopic infarcts, and neocortical Lewy bodies were identified, and measures of β-amyloid burden and tau-positive tangle density in multiple brain regions were derived.
  • Conclusions: More frequent cognitive activity across the life span has an association with slower late-life cognitive decline that is independent of common neuropathologic conditions, consistent with the cognitive reserve hypothesis.

Sustaining attention to simple tasks: A meta-analytic review of the neural mechanisms of vigilant attention. [feedly]


 
Shared via feedly // published on Psychological Bulletin - Vol 139, Iss 4 // visit site
Sustaining attention to simple tasks: A meta-analytic review of the neural mechanisms of vigilant attention.
Maintaining attention for more than a few seconds is essential for mastering everyday life. Yet, our ability to stay focused on a particular task is limited, resulting in well-known performance decrements with increasing time on task. Intriguingly, such decrements are even more likely if the task is cognitively simple and repetitive. The attentional function that enables our prolonged engagement in intellectually unchallenging, uninteresting activities has been termed vigilant attention. Here we synthesized what we have learned from functional neuroimaging about the mechanisms of this essential mental faculty. To this end, a quantitative meta-analysis of pertinent neuroimaging studies was performed, including supplementary analyses of moderating factors. Furthermore, we reviewed the available evidence on neural time-on-task effects, additionally considering information obtained from patients with focal brain damage. Integrating the results of both meta-analysis and review, we identified a set of mainly right-lateralized brain regions that may form the core network subserving vigilant attention in humans, including dorsomedial, mid- and ventrolateral prefrontal cortex, anterior insula, parietal areas (intraparietal sulcus, temporoparietal junction), and subcortical structures (cerebellar vermis, thalamus, putamen, midbrain). We discuss the potential functional roles of different nodes of this network as well as implications of our findings for a theoretical account of vigilant attention. It is conjectured that sustaining attention is a multicomponent, nonunitary mental faculty, involving a mixture of (a) sustained/recurrent processes subserving task-set/arousal maintenance and (b) transient processes subserving the target-driven reorienting of attention. Finally, limitations of previous studies are considered and suggestions for future research are provided. (PsycINFO Database Record (c) 2013 APA, all rights reserved)
