Aphasia is associated with impairments in written language, including difficulty with sentence formulation, word finding, and editing. While writing aids show promise, artificial intelligence (AI) tools, such as large language models (LLMs), offer new opportunities for individuals with language-based writing challenges.
This case report describes the use of the LLM, ChatGPT, to improve accuracy, complexity, and productivity in an adult with aphasia. The intervention combined self-genrated content with AI-assisted editing, guided by a visual flow char and structured prompts. Writing samples were analyzed for sentence count, complexity, and errors, while the patient's attitudes toward writing were evaluated through surveys.
When using ChatGPT, the patient produced more sentences with fewer errors, while self-written samples showed reduced total errors but decreased sentence production and increased sentence length and syntactic complexity. Although the patient required clinician prompting and modeling to use ChatGPT effectively, he developed greater independence and confidence over time. One year later, he reported continued use of ChatGPT for creative and communicative tasks.
This case highlights how AI tools can enhance written communication and promote participation in meaningful activities for individuals with aphasia, especially those with prior experience using technology.
失语症与书面语言障碍有关，包括句子构建、词汇查找和编辑方面的困难。虽然写作辅助工具显示出前景，但人工智能（AI）工具，如大语言模型（LLMs），为有基于语言的写作挑战的个体提供了新机会。
本病例报告描述了使用大语言模型ChatGPT提高一名成年失语症患者写作的准确性、复杂性和效率的情况。干预措施将自我生成的内容与人工智能辅助编辑相结合，由视觉流程图和结构化提示引导。分析写作样本的句子数量、复杂性和错误，同时通过调查评估患者对写作的态度。
使用ChatGPT时，患者写出的句子更多，错误更少，而自我书写的样本总错误减少，但句子数量减少，句子长度和句法复杂性增加。尽管患者需要临床医生的提示和示范才能有效使用ChatGPT，但随着时间的推移，他变得更加独立和自信。一年后，他报告仍在使用ChatGPT进行创造性和交流性任务。
本病例突出了人工智能工具如何能够增强失语症患者的书面交流能力，并促进他们参与有意义的活动，尤其是那些有使用技术经验的患者。
