Although wandering is a common behavioral problem in patients with dementia, information about wandering in patients with severe dementia is scarce. This study analyzed data about the wandering behavior of a 77-year-old woman with severe frontotemporal dementia. Due to severe atrophy of the anterior cortex, she was totally unable to act spontaneously. Nevertheless, she walked with her husband every day. Her walking pattern varied on a daily basis but it appeared to be random. However, a mathematical analysis showed that her walking pattern was not random. Our case suggests that even patients with severe atrophy in the anterior cortex may be able to orient themselves within their neighborhood if their posterior cortex is preserved.
尽管徘徊是痴呆症患者常见的行为问题，但关于重度痴呆症患者徘徊的信息却很少。本研究分析了一名77岁重度额颞叶痴呆女性的徘徊行为数据。由于前额叶皮质严重萎缩，她完全无法自主行动。然而，她每天都和丈夫一起散步。她的行走模式每天都有所不同，但似乎是随机的。然而，数学分析表明她的行走模式并非随机。我们的病例表明，即使前额叶皮质严重萎缩的患者，如果其枕叶皮质保存完好，也可能能够在其周边区域定向。
