abstract = {Primary progressive aphasias (PPAs) are a group of
neurodegenerative diseases mainly characterized by language
impairment, and with variably presence of dysexecutive
syndrome, behavioural disturbances and parkinsonism.
Detailed knowledge of neurotransmitters impairment and its
association with clinical features hold the potential to
develop new tailored therapeutic approaches. In the present
study, we applied JuSpace toolbox, which allowed for
cross-modal correlation of magnetic resonance imaging
(MRI)-based measures with nuclear imaging derived estimates
covering various neurotransmitter systems including
dopaminergic, serotonergic, noradrenergic, GABAergic and
glutamatergic neurotransmission. We included 103 PPA
patients and 80 age-matched healthy controls (HC). We tested
if the spatial patterns of grey matter volume (GMV)
alterations in PPA patients (relative to HC) are correlated
with specific neurotransmitter systems. As compared to HC,
voxel-based brain changes in PPA were significantly
associated with spatial distribution of serotonin, dopamine,
and glutamatergic pathways (p < .05, False Discovery Rate
corrected-corrected). Disease severity was negatively
correlated with the strength of GMV colocalization of D1
receptors (p = .035) and serotonin transporter (p
= .020). Moreover, we observed a significant negative
correlation between positive behavioural symptoms, as
measured with Frontal Behavioural Inventory, and GMV
colocalization of D1 receptors (p = .007) and serotonin
transporter (p < .001). This pilot study suggests that
JuSpace is a helpful tool to indirectly assess
neurotransmitter deficits in neurodegenerative dementias and
may provide novel insight into disease mechanisms and
associated clinical features.},
