abstract = {Background and Objective: Apraxia is a deficit of motor
cognition leading to difficulties in actual tool use,
imitation of gestures, and pantomiming object use. To date,
little data exist regarding the recovery from apraxic
deficits after stroke, and no statistical lesion mapping
study investigated the neural correlate of recovery from
apraxia. Accordingly, we here examined recovery from apraxic
deficits, differential associations of apraxia task
(imitation vs. pantomime) and effector (bucco-facial vs.
limb apraxia) with recovery, and the underlying neural
correlates. Methods: We assessed apraxia in 39 patients with
left hemisphere (LH) stroke both at admission and
approximately 11 days later. Furthermore, we collected
clinical imaging data to identify brain regions associated
with recovery from apraxic deficits using voxel-based
lesion-symptom mapping (VLSM). Results:Between the two
assessments, a significant recovery from apraxic deficits
was observed with a tendency of enhanced recovery of limb
compared to bucco-facial apraxia. VLSM analyses revealed
that within the lesion pattern initially associated with
apraxia, lesions of the left insula were associated with
remission of apraxic deficits, whereas lesions to the
(inferior) parietal lobe (IPL; supramarginal and angular
gyrus) and the superior longitudinal fasciculus (SLF) were
associated with persistent apraxic deficits. Conclusions:
Data suggest that lesions affecting the core regions (and
white matter) of the fronto-parietal network cause more
persistent apraxic deficits than lesions affecting other
regions (here: the left insula) that also contribute to
motor cognition and apraxic deficits.},
