Researchers used artificial intelligence to analyze speech in Parkinson's disease patients, revealing distinct patterns. The AI found Parkinson's patients used more verbs but fewer nouns and fillers in their speech, even before cognitive decline typically associated with PD was evident. The analysis was capable of identifying Parkinson's patients with over 80% precision, offering a potential new tool for early diagnosis. This study underscores the potential of natural language processing, a branch of AI, in enhancing healthcare diagnostics.
