Repeated Transcranial Magnetic Stimulation in the Elderly With Cognitive Impairment

Participants in this group receive high-frequency TMS at 40 Hz. The TMS intervention is applied to the bilateral dorsolateral prefrontal cortex (DLPFC). Each patient undergoes this TMS treatment for a course of 10 consecutive working days. The specific parameters for TMS include pulses at 40 Hz with an intensity set at 40% of the maximum intensity. Each pulse lasts for 2 seconds, followed by a 58-second rest period. On each treatment day, patients receive 30 sets of stimulation, with 15 stimulations applied to the left side and 15 to the right side, totaling 2400 pulses.

Participants in this group receive moderately high-frequency TMS at 10 Hz. Similar to the high-frequency group, the TMS intervention targets the bilateral dorsolateral prefrontal cortex (DLPFC) and is administered for a course of 10 consecutive working days. The TMS parameters for this group involve pulses at 10 Hz with an intensity set at 90% of the maximum intensity. Each pulse lasts for 4 seconds, followed by a 56-second rest period. As in the high-frequency group, patients in this group also receive 30 sets of stimulation per treatment day, with 15 stimulations applied to the left side and 15 to the right side, totaling 2400 pulses.
