Brain stimulation improves associative memory in an individual with amnestic mild cognitive impairment

In patients with cognitive deficits, brain stimulation has been shown to restore cognition ( Miniussi et al., 2008 , Brain Stimulation, 1, 326). The aim of this study was to assess whether repetitive Transcranial Magnetic Stimulation (rTMS) could improve memory performance in an individual with amnestic Mild Cognitive Impairment (aMCI). Stimulation of the left parietal cortex increased accuracy in an association memory task, and this improvement was still significant 24 weeks after stimulation began. These findings indicate that rTMS to the left parietal cortex improved memory performance in aMCI.
