Brain stimulation technique boosts language ability in Alzheimer's patientsImproved language performance in Alzheimer's disease following brain stimulation online firstA brain stimulation technique, known as repetitive transcranial magnetic stimulation, boosts the language ability of patients with Alzheimer's disease, suggests preliminary research, published online in the Journal of Neurology, Neurosurgery and Psychiatry.Repetitive transcranial magnetic stimulation, or rTMS for short, is a non-invasive technique that involves the delivery of a rapid succession of magnetic pulses in frequencies of up to 100 Hz.Previous research has shown that this can alter neuronal activity, depending on the frequency of the stimulation.The technique, which was applied to the prefrontal lobes for 25 minutes each time at a frequency of 20 Hz, was tested in 10 patients with moderate Alzheimer's disease.Half were randomly assigned to receive four weeks of rTMS (five days a week), and half were given a dummy treatment for two weeks, followed by two weeks of rTMS.Each participant was tested for memory, executive functions, such as planning, and language at the start of the study, then after two and four weeks, and again after eight weeks.Significant differences emerged between the two groups after two weeks in respect of the ability of participants to understand spoken language.The percentage of correct answers after a comprehension test rose from 66% to over 77% among those given rTMS, whereas there was no change in those given the dummy technique.There was no further change after four weeks, but the improvements were still evident at eight weeks.
