Shortage of drugs to treat ADHD

November 21, 2011

NPR reports that a shortage of drugs used to treat attention challenges, including ADHD, has left parents scrambling to fill prescriptions for their kids. In some cases, parents who are also medicated for attention challenges are having to share their medication with a child.

According to the story, affected drugs include Adderall and the active ingredient in Ritalin.

Full article, including a link to audio of a Morning Edition story covering the shortages is on NPR’s Web site.

Developing spatial vocabulary in infants

November 3, 2011

In a recent collection of essays, “Manhood for Amateurs,” one of my favorite writers, Michael Chabon, laments a development in the world of Legos, namely that they now come almost exclusively in kits with detailed instructions, designed to be assembled in a particular way to create a specific space ship or tractor. Gone, says Chabon, are the days of starting with a bin full of Legos of all sizes, shapes and colors, and creating, well, something creative.

Fortunately, some new research indicates that all might not be lost. In fact, “guided play,” in which participants are given blocks along with graphic instructions for creating a particular structure, generates higher levels of “spatial talk” than free play. The research was performed at Temple University’s Infant Lab, and recently highlighted by Science Daily:

The researchers found that when playing with blocks under interactive conditions, children hear the kind of language that helps them think about space, such as “over,” “around” and “through.”

“When parents use spatial language, they draw attention to spatial concepts,” said Nora Newcombe, co-director of Temple’s Infant Lab. “The development of a spatial vocabulary is critical for developing spatial ability and awareness.”

Spatial skills, says the Science Daily article, “are important for success in the STEM (science, technology, engineering and math) disciplines, but they are also involved in many everyday tasks, such as packing the trunk of a car or assembling a crib. They are a central component of intellect and, as those who struggle finding their way around a new city can attest, they show marked individual differences.”

So Chabon’s laments aside, it’s OK, and maybe even good, to pick up that Star Wars Lego kit and build the Death Star just like the picture on the box.

Ruminations of a brain scientist who also likes to party

November 2, 2011

Tuesday’s NY Times has a fascinating profile of Dr. Michael Gazzaniga, a professor of psychology at the University of California, Santa Barbara, who led pioneering research into the interaction of the various systems of the brain. Dr. Gazzaniga’s research focused on patients who had surgery to separate the hemispheres of the brain (used as a treatment for severe epilepsy). The research uncovered the presence of a left-brain-centered brain narrating system that creates a coherent voice from the inputs of many brain systems.

The Times article summarizes Dr. Gazzaniga’s research, but also provides some insight into the man who, among other things, was a member of the fraternity at Dartmouth that inspired the movie “Animal House”, and who says of his fellow researchers at Cal Tech “we weren’t intellectuals, in the sense that we were going out to see people lecturing or cultural events in the evening. That was martini time.” The profile of Dr. Gazzaniga by the Times is part of its series about leaders in science, and includes a video interview.

Dr. Gazzaniga’s new book, which examines the implications of the brain’s narrator for free will is called “Who’s in Charge? Free Will and the Science of the Brain.” It’s scheduled for release later this month.
