Some patients with frontotemporal lobar degeneration have developed artistic skills after the onset mainly in painting and music. Most of these cases have semantic dementia (SD), one of the frontotemporal lobar degeneration subtypes. In previously reported cases, the paintings made by patients with SD were usually hyper realistic, without a significant symbolic or abstract component. Here, we report on a patient with progressive nonfluent aphasia (PNFA), another frontotemporal lobar degeneration subtype, who started making creative bamboo crafts after PNFA onset. His techniques were completely his original; he devised the shapes of the crafts and made them without samples. His work did not become an obsessive preoccupation. The artistic style expressed by patients with PNFA differs from that expressed by patients with SD. Therefore, the underlying mechanisms for the emergence of artistic talent might differ between SD and PNFA.
一些额颞叶变性患者在发病后主要表现为绘画和音乐等艺术技能的发展。这些病例大多数为额颞叶变性的一个亚型——语义性痴呆（SD）。在之前报道的病例中，SD 患者的画作通常是超写实的，没有明显的象征或抽象成分。在这里，我们报告了一例进行性非流利性失语（PNFA）患者，PNFA 是额颞叶变性的另一个亚型，在发病后开始制作有创意的竹制工艺品。他的技艺完全是原创的；他设计出工艺品的形状，并且在没有样本的情况下制作它们。他的作品并没有成为一种强迫性的痴迷。PNFA 患者所表现出的艺术风格与 SD 患者不同。因此，SD 和 PNFA 患者艺术天赋的出现机制可能不同。
