Study: Brain imaging not accurate or sensitive enough (yet) to detect Alzheimer’s disease in primary care settings

dementia_pet_imagingAccu­ra­cy of demen­tia brain imag­ing must improve (Uni­ver­si­ty of East Anglia release):

A report pub­lished today in The Lancet Neu­rol­o­gy eval­u­ates for the first time how well dif­fer­ent types of brain imag­ing tests work to detect Alzheimer’s and pre­dict how the dis­ease will progress.

The results show that the accu­ra­cy of brain imag­ing must be improved before it can be rolled out Read the rest of this entry »

Looking inside the Brain: is my Brain Fit?

MRI scanner neuroimaging

Today we have the plea­sure to have Dr. Pas­cale Mich­e­lon, one of our new Expert Con­trib­u­tors, write her first arti­cle here. Enjoy, and please com­ment so we hear your thoughts and engage in a nice con­ver­sa­tion.

(Btw, if you notice some sim­i­lar­i­ty between the col­ors in the fMRI scan below and the look & feel of this site…well, the rea­son is that those orange-grey fMRI col­ors were our inspi­ra­tion! the orange col­or denotes the most brain acti­va­tion).

You have prob­a­bly heard about CAT and MRI scans (pro­duced thanks to machines like the one to the top right). So you know that these are tech­niques that doc­tors and sci­en­tists use to look inside the brain.

You have prob­a­bly also heard about brain fit­ness and how impor­tant it is to keep a healthy brain to be pro­tect­ed against age-relat­ed and dis­ease-relat­ed brain dam­ages.

The ques­tion we ask here is the fol­low­ing: Can we use brain scans to eval­u­ate how fit the brain is? Before we try to answer this ques­tion let’s start with the basics and try to under­stand how brain scans work.

Brain imag­ing, also called neu­roimag­ing, allows one to Read the rest of this entry »

Discover the Brain

Hot off the press!

We just found on the new­stand an amaz­ing spe­cial issue of Dis­cov­er mag­a­zine on The Brain-An Owner’s Man­u­al (Spring 2007), with fas­ci­nat­ing arti­cles on how the mind changes from infan­cy to old age, female vs. male brains (yes, we men have brains too), videogames as brain train­ing (by Steven John­son), an arti­cle titled “24 hours in the life of the brain”, the “most mag­nif­i­cent neu­rons, and much much more.

A bit tech­ni­cal, but not too much for any­one who reads pop­u­lar sci­ence books. It will prob­a­bly become a clas­sic for brain afi­ciona­dos. We can not find any men­tion of it in www.discover.com, so we will keep our eyes open and link to the index and more info as soon as we find some­where to link to…
