Repetitive transcranial magnetic stimulation effects on brain function and cognition among elders with memory dysfunction. A randomized sham-controlled study.

In the present study, we aimed to investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on memory performance and brain activity in elders presenting with subjective memory complaints and a memory performance within the low normal range. Forty participants underwent 2 functional magnetic resonance imaging (fMRI) sessions, in which they were administered 2 equivalent face-name memory tasks. Following each fMRI, subjects were asked to pair faces with their corresponding proper name.

Apolipoprotein E gender effects on cognitive performance in age-associated memory impairment.

Among 100 individuals with age-associated memory impairment (AAMI), APOE E4 carriers performed worse on memory. However, when subjects were considered by gender, this effect was only observed in females. APOE E4 may have a more robust cognitive influence on female than on male individuals with AAMI.
