Abstract: This review of our research with rTMS to treat aphasia contains four
parts: Part 1 reviews functional brain imaging studies related to recovery of
language in aphasia with emphasis on nonfluent aphasia. Part 2 presents the
rationale for using rTMS to treat nonfluent aphasia patients (based on results
from functional imaging studies). Part 2 also reviews our current rTMS
treatment protocol used with nonfluent aphasia patients, and our functional
imaging results from overt naming fMRI scans, obtained pre- and post- a series
of rTMS treatments. Part 3 presents results from a pilot study where rTMS
treatments were followed immediately by constraint-induced language therapy
(CILT). Part 4 reviews our diffusion tensor imaging (DTI) study that examined
white matter connections between the horizontal, midportion of the arcuate
fasciculus (hAF) to different parts within Broca's area (pars triangularis,
PTr; pars opercularis, POp), and the ventral premotor cortex (vPMC) in the RH
and in the LH. Part 4 also addresses some of the possible mechanisms involved
with improved naming and speech, following rTMS with nonfluent aphasia
patients.
