Increasingly bizarre and menacing caricatures by an artist with frontotemporal lobar degeneration during the course of his illness. From left, the first picture drawn many years before his illness; the middle pair in the first 2 years of dementia; and that on the right at least 3 years into the illness. Background: Gouache entitled ‘Unravelling Boléro’, showing de novo transmodal creativity comprising auditory to visual transformation, by a patient with primary progressive aphasia (see Brain 2008; 131: 39–49). Composite images from Schott. Pictures as a neurological tool: lessons from enhanced and emergent artistry in brain disease (pp. 1947–1963).
