(Editor’s Note: given the growing media attention to three apparently separate worlds -cognitive enhancement via drugs, brain fitness training software, computerized neurocognitive assessments-, I found it refreshing to see our co-founder Elkhonon Goldberg introduce the topic of cognotropic drugs with an integrative perspective in the much updated new edition of his classic book, now titled The New Executive Brain: Frontal Lobes In A Complex World. Below goes an excerpt).

For many neuropsychologists, like myself, science is a labor of love, but seeing patients is bread and butter. Traditionally, the clinical contribution of neuropsychology has been mostly diagnostic, with precious little to offer patients by way of treatment. Neuropsychology is not the only clinical discipline for years consigned to helpless voyeurism. Every discipline concerned with cognition shares this humbling predicament. A psychiatrist treating a schizophrenic patient or a depressed patient finds him- or herself in a similar position. There are ample pharmacological tools to treat the patient’s psychosis or mood, but very few to treat the patient’s cognition. Even though psychiatrists increasingly recognize that cognitive impairment is often more debilitating in their patients than psychosis or mood disorder, traditionally, very little direct effort has been aimed at improving cognition.

A neurologist treating a patient recovering from the effects of head injury does not fare much better. There are adequate means to control the patient’s seizures but not his or her cognitive changes, despite the fact that cognitive impairment is usually far more debilitating than an occasional seizure. Society has been so preoccupied with saving lives, treating hallucinations, controlling seizures, and lifting depression that cognition (memory, attention, planning, problem solving) has been largely ignored. Granted, various neuroleptics, anticonvulsants, antidepressants, sedatives, and stimulants do have an effect on cognition, but it is an ancillary effect of a drug designed to treat something else.

Alzheimer’s disease and other dementias have been society’s wake-up call. Here, in the most affluent country in the most affluent of times, human minds were succumbing to decay before human bodies, a sharp challenge to the tacit popular belief that the “body is frail but soul is forever.” This provided an impetus for the development of an entirely new class of drugs, which can be termed familially as “cognotropic.” Their primary and explicit purpose is to improve cognition.

Since medical and public preoccupation with dementia focuses on memory, most of the pharmacological efforts have been directed at improving memory. At the time of this writing, a handful of drugs known as “Alzheimer’s drugs” or “memory enhancers” have been approved by the U.S. Food and Drug Administration (FDA). In reality, both designations are somewhat misleading. The drugs in question are Read the rest of this entry »

Yes, You Can:

New research suggests we can build our willpower

– By Daniel Goleman

Those of us who struggle to resist junk foods or otherwise suffer a lack of willpower will be heartened by some good news from neuroscience. But there’s some bad news, too.

First, the bad news. A slew of studies suggest that we each have a fixed neural reservoir of willpower, and that if we use it on one thing, we have less for others. Tasks that demand some self-control make it harder for us to do the next thing that takes willpower.

In a typical experiment on this effect, one group of people was made to watch a video of a boring scene; another was not. Then both groups had to circle every “e” in a long passage of writing. The result? The people who had to first sit through the boring video gave up faster. The same loss of persistence has been found when people try to resist tempting foods, suppress emotional reactions, or even make the effort to try to impress someone.

This all suggests we have a fixed willpower budget, one we should be careful in spending. Some neuroscientists suspect that self-control consumes blood sugar, which takes a while to build up again; thus, the depletion effect.

But the good news is that we can grow our willpower; like a muscle, the more we use it, the more it gradually increases over time. But doing this takes, of all things, willpower.

As the muscle of will grows, the larger our reservoir of self-discipline becomes. So people who are able to Read the rest of this entry »

Like all psychiatric disorders, ADHD is diagnosed based on the presence of particular behavioral symptoms that are judged to cause significant impairment in an individual’s functioning, and not on the results of a specific test. In fact, recently published ADHD evaluation guidelines from the American Academy of Pediatrics (AAP) explicitly state that no particular diagnostic test should be routinely used when evaluating a child for ADHD.

While most ADHD experts would agree that no single test could or should be used in isolation to diagnose ADHD, there are several important reasons why the availability of an accurate objective test would be useful.

First, many children do not receive a careful and comprehensive assessment for ADHD but are instead diagnosed with based on evaluation procedures that are far from optimal.

Second, although AAP guidelines indicate that specific diagnostic tests should not be routinely used, many parents are concerned about the lack of objective procedures in their child’s evaluation. In fact, many families do not pursue treatment for ADHD because the the absence of objective evaluation procedures leads them to question the diagnosis. You can read a review of an interesting study on this issue at www.helpforadd.com/2006/january.htm

For these reasons an accurate and objective diagnostic test for ADHD could be of value in many clinical situations. Two important conditions would have to be met for such a test to be useful.

First, it would have to be highly sensitive to Read the rest of this entry »

Great article in the New York Times titled Training Young Brains to Behave. A couple of quotes:

- “But just as biology shapes behavior, so behavior can accelerate biology. And a small group of educational and cognitive scientists now say that mental exercises of a certain kind can teach children to become more self-possessed at earlier ages, reducing stress levels at home and improving their experience in school. Researchers can test this ability, which they call executive function, and they say it is more strongly associated with school success than I.Q.”

- “We know that the prefrontal cortex is not fully developed until the 20s, and some people will ask, Read the rest of this entry »

A recent CNN article explains well why a growing number of companies use brainteasers and logic puzzles of a type called “guesstimations” during job interviews:

- “Seemingly random questions like these have become commonplace in Silicon Valley and other tech outposts, where companies aren’t as interested in the correct answer to a tough question as they are in how a prospective employee might try to solve it. Since businesses today have to be able to react quickly to shifting market dynamics, they want more than engineers with high IQs and good college transcripts. They want people who can think on their feet.”

What are technology companies (Google, Microsoft, Amazon) and consulting companies (McKinsey, Boston Consulting Group, Accenture…) looking for? They want employees with good so-called Executive Functions: problem-solving, cognitive flexibility, planning, working memory, decision-making, even emotional self-regulation (don’t try to solve one of these puzzles while being angry, or stressed out).

Some very interesting brain fitness software market news:

1) Scientific Learning To Buy Out Soliloquy

- “Scientific Learning Corp. has announced that it will acquire Soliloquy Learning from JTT Holdings. Both Scientific Learning and Soliloquy provide technology solutions for education. The acquisition will cost SLC about $11 million and is expected to be completed this month.”

- “Scientific Learning is the developer of Fast ForWord, a family of reading intervention tools targeted toward students who are characterized as struggling learners and designed to develop the required “neurocognitive skills” for reading and learning in general. Soliloquy is also a reading intervention developer.”

Comment: this acquisition consolidates Scientific Learning (NSDQ: SCIL) as the leading company in the education segment of the brain fitness market. It will be interesting to track what research gets done on the neural and cognitive effects of Soliloquy, since Scientific Learning’s Fast Forword is backed by extensive literature.

2) Technomedia Partners With SBT to Accelerate Its International Expansion

- “Technomedia, a Canadian provider of talent management and human capital development solutions, announced its partnership with the SBT (Scientific Brain Training) group, a European provider of training and evaluation of cognitive functions.” Read the rest of this entry »
