Digital Dementia? AI Shows Surprising Signs of Cognitive Decline

Almost all leading large language models, or “chatbots,” show signs of mild cognitive impairment when tested using assessments commonly used to detect early dementia, according to a study published in the Christmas issue of The BMJ.

The study also found that older versions of these chatbots, much like aging human patients, performed worse on the tests. The authors suggest that these findings “challenge the assumption that artificial intelligence will soon replace human doctors.”

The instructions given to the LLMs for each task were the same as those given to human patients. Scoring followed official guidelines and was evaluated by a practicing neurologist.

ChatGPT 4o achieved the highest score on the MoCA test (26 out of 30), followed by ChatGPT 4 and Claude (25 out of 30), with Gemini 1.0 scoring lowest (16 out of 30).

Challenges in Visual and Executive Functions

All chatbots showed poor performance in visuospatial skills and executive tasks, such as the trail-making task (connecting encircled numbers and letters in ascending order) and the clock drawing test (drawing a clock face showing a specific time). Gemini models failed at the delayed recall task (remembering a five-word sequence).

Most other tasks, including naming, attention, language, and abstraction were performed well by all chatbots.
