<p><b><i>Background/Aims:</i></b> Although some patients with primary
progressive aphasia (PPA) exhibit novel or improved skills after the
onset of dementia, these changes have yet to be quantified. Therefore,
this study systematically explored and identified the emergence of
positive behaviours after dementia onset. <b><i>Methods:</i></b> This
study included 48 carers of patients with PPA: 12 nonfluent/agrammatic
PPA (nfvPPA), 22 semantic variant PPA (svPPA), and 14 logopenic variant
PPA (lvPPA). The presence and frequency of positive behaviour changes
after dementia onset were established using the Hypersensory and
Social/Emotional Scale (HSS). <b><i>Results:</i></b> Scores on
Sensitivity to Details, Visuospatial Activities, and Music Activities
differed significantly among the groups. More specifically, svPPA was
associated with increased visuospatial activity, but only in the mild
stage of the disease; nfvPPA was associated with increased visuospatial
activity and decreased music activity, while lvPPA exhibited the reverse
profile. <b><i>Conclusions:</i></b> The results demonstrate that
subsets of PPA patients show novel or increased positive behaviours
following dementia onset, and differences among subtypes may be helpful
for improving diagnostic accuracy. Additionally, harnessing these skills
may improve the quality of life of both patients and carers.</p>
