Brief Summary

Primary Progressive Aphasia (PPA) is a neurodegenerative disease in which language function is gradually and progressively impaired. Patients will eventually be disabled in communication and have cognition deficits, which put a heavy burden not only on their families but also on the whole society. However, no effective treatment for PPA has been explored so far. The current clinical randomized trial is to study the safety and efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) for the treatment of PPA. Also, multi-modality of neuroimaging techniques, such as functional MRI and PET will be used to investigate brain network changing in this procedure.

Study Arms (2)

rTMS treatment group

EXPERIMENTAL

The participants will be divided into the rTMS treatment group and the sham treatment group by means of randomized methods.The protocol of the treatment is to use rTMS with high frequency 10/20Hz 120%RMT 20 times for one month. The device is Magtism rTMS made in London, UK

Device: Magstim rTMS

sham treatment group

SHAM COMPARATOR

The control group is to receive sham treatment. The device is the same as the one used in the real treatment group.

Device: Magstim rTMS

Interventions

The device is made in London,UK
