Cognitive Tests Help Determine who can Drive Safely after a Stroke

by

The same way a brain fit­ness soft­ware pro­gram can help increase dri­ving safe­ty for old­er adults, sim­ple cog­ni­tive tests may help deter­mine whether a per­son can dri­ve safe­ly after a stroke.

A recent study ana­lyzed 30 pre­vi­ous stud­ies in which the par­tic­i­pants’ dri­ving skills after a stroke were test­ed in an on-road eval­u­a­tion. 1,728 indi­vid­u­als with an aver­age age of 61 were involved. On aver­age, 9 months had passed between the stroke and the dri­ving eval­u­a­tion. Note that 54 per­cent of the par­tic­i­pants passed the on-road evaluation.

The authors of the analy­sis looked for tests scores that could pre­dict the actu­al dri­ving eval­u­a­tion out­come. They iden­ti­fied 3 sim­ple cog­ni­tive tests that did quite well: [Read more…] about Cog­ni­tive Tests Help Deter­mine who can Dri­ve Safe­ly after a Stroke

Improving Driving Skills and Brain Functioning- Interview with ACTIVE’s Jerri Edwards

by

Jerri Edwards- Active trialToday we are for­tu­nate to inter­view Dr. Jer­ri Edwards, an Asso­ciate Pro­fes­sor at Uni­ver­si­ty of South Flori­da’s School of Aging Stud­ies and Co-Inves­ti­ga­tor of the influ­en­cial ACTIVE study. Dr. Edwards was trained by Dr. Kar­lene K. Ball, and her research is aimed toward dis­cov­er­ing how cog­ni­tive abil­i­ties can be main­tained and even enhanced with advanc­ing age.

Main focus of research

Alvaro Fer­nan­dez: Please explain to our read­ers your main research areas 

Jer­ri Edwards: I am par­tic­u­lar­ly inter­est­ed in how cog­ni­tive inter­ven­tions may help old­er adults to avoid or at least delay func­tion­al dif­fi­cul­ties and there­by main­tain their inde­pen­dence longer. Much of my work has focused on the func­tion­al abil­i­ty of dri­ving includ­ing assess­ing dri­ving fit­ness among old­er adults and reme­di­a­tion of cog­ni­tive decline that results in dri­ving difficulties.

Some research ques­tions that inter­est me include, how can we main­tain health­i­er lives longer? How can train­ing improve cog­ni­tive abil­i­ties, both to improve those abil­i­ties and also to slow-down, or delay, cog­ni­tive decline? The spe­cif­ic cog­ni­tive abil­i­ty that I have stud­ied the most is pro­cess­ing speed, which is one of the cog­ni­tive skills that decline ear­ly on as we age.

ACTIVE results

Can you explain what cog­ni­tive pro­cess­ing speed is, and why it is rel­e­vant to our dai­ly lives? 

Pro­cess­ing speed is men­tal quick­ness. Just like a com­put­er with a 486 proces­sor can do a lot of the same things as a com­put­er with a Pen­tium 4 proces­sor, but it takes much longer, our minds tend to slow down with age as com­pared to when we were younger. We can do the same tasks, but it takes more time. Quick speed of pro­cess­ing is impor­tant for [Read more…] about Improv­ing Dri­ving Skills and Brain Func­tion­ing- Inter­view with ACTIVE’s Jer­ri Edwards

#14 Brain Teaser: Party For Polyglots

by

We are delight­ed to intro­duce you to Wes Car­roll who has gra­cious­ly cre­at­ed a few new puz­zles to bend all those sharp brains out there! Wes Carroll

Wes is the head of Do The Math pri­vate tutor­ing ser­vices, Puz­zle Mas­ter for the Ask A Sci­en­tist lec­ture series, and an inter­na­tion­al­ly tour­ing per­former and teacher of music. With no fur­ther ado, the first puzzle!

Par­ty For Polyglots

Dif­fi­cul­ty: MEDIUM
Type: LOGIC

QUESTION:
Of the 100 peo­ple at a recent par­ty, 90 spoke Span­ish, 80 spoke Ital­ian, and 75 spoke Man­darin. At least how many spoke all three languages?

Have you solved it yet? If you are work­ing the prob­lem, mak­ing hypothe­ses, test­ing your ideas, and com­ing up with a solu­tion, you are using your frontal lobes. This is great exer­cise because the frontal lobes fol­low the “last hired, first fired” adage. They are they last areas of your brain to devel­op and the first to suf­fer the rav­ages of time and stress. So, keep exer­cis­ing them!

ANSWER:
45

EXPLANATION:
10 could not speak Span­ish, 20 could not speak Ital­ian, and 25 could not speak Man­darin. So there could have been 10 peo­ple who spoke none of those languages.

How­ev­er, that would max­i­mize the num­ber of peo­ple who could speak all three, and the prob­lem asks at least how many speak all three. There­fore, we must assume that these 10, 20, and 25 peo­ple are all sep­a­rate peo­ple. Hav­ing iden­ti­fied 55 each of whom is miss­ing one lan­guage, the remain­ing 45 speak all three.
