Google has been accused of hiding AI search results when users seek information about whether 79-year-old Donald Trump has dementia. There is a notable difference between the AI search results for questions about Donald Trump and Joe Biden's mental health. When switched to AI mode, Google does not provide a generated summary of information. There is also no AI summary if you search for whether Trump shows signs of Alzheimer’s. “Assessing whether Joe Biden shows signs of dementia is a complex question with various perspectives and differing conclusions,” Google’s AI mode states.
