Emergence of artistic talent in logopenic variant of primary progressive aphasia: a case report.

The case report covers the investigation of a 59-year-old woman, with the diagnosis of logopenic variant of primary progressive aphasia (lvPPA), who presented de novo visual artistic talent after the onset of language deficits. Similar cases have been described in patients with semantic and non-fluent/agrammatic variants of primary progressive aphasia. However, this is the first related case with lvPPA reported in the literature. Upon her initial visit at the Neurology department in 2020, a neurological and neuropsychological assessment were conducted to establish the diagnosis. A neuropsychological reassessment was performed in 2022. Neuroimaging data indicated decreased blood flow of the left hemisphere, while neuropsychological deficits were diffuse with predominant language production disorder. A description of the patient's portraits and suggestions regarding possible neural mechanisms associated with the manifestation of this ability are provided.
