___

Prac­tice Imper­fect: Repeat­ed Cog­ni­tive Test­ing Can Obscure Ear­ly Signs of Demen­tia (UC San Diego Health press release):

Alzheimer’s dis­ease (AD) is a pro­gres­sive, neu­rode­gen­er­a­tive con­di­tion that often begins with mild cog­ni­tive impair­ment or MCI, mak­ing ear­ly and repeat­ed assess­ments of cog­ni­tive change cru­cial to diag­no­sis and treat­ment.

But in a paper pub­lished online in the jour­nal Alzheimer’s & Demen­tia: Diag­no­sis, Assess­ment & Dis­ease Mon­i­tor­ing, a team of researchers led by sci­en­tists at the Uni­ver­si­ty of Cal­i­for­nia San Diego School of Med­i­cine found that repeat­ed test­ing of mid­dle-age men pro­duced a “prac­tice effect” which obscured true cog­ni­tive decline and Read the rest of this entry »

Brain Gain: Com­put­er­ized Train­ing May Boost Cog­ni­tion in MCI (Med­scape):

Com­put­er­ized cog­ni­tive train­ing (CCT) for patients with mild cog­ni­tive impair­ment (MCI) appears to have a ben­e­fi­cial effect on glob­al cog­ni­tion, mem­o­ry, and atten­tion and improves psy­choso­cial func­tion­ing, includ­ing depres­sive symp­toms, Read the rest of this entry »

Status quo is not enough: Common tests for Mild Cognitive Impairment lack both sensitivity and specificity

misdiagnosisCur­rent screen­ing meth­ods miss wor­ri­some num­ber of per­sons with mild cog­ni­tive impair­ment (Sci­enceDai­ly):

Mild cog­ni­tive impair­ment (MCI) is a slight but notice­able and mea­sur­able decline in cog­ni­tive abil­i­ties, such as remem­ber­ing names or a list of items. While changes may not be severe enough to dis­rupt dai­ly life, a clin­i­cal diag­no­sis Read the rest of this entry »
