AI reliance may be harming brain function
The gist
Neurosurgeon Nigel Peter Symss says excessive AI reliance may reduce practice at remembering and analysing independently.
He says evidence of permanent brain damage is lacking; long-term effects stay uncertain.
How it unfolded
- Oct 31, 2026A Guardian opinion piece argued that overusing AI affects the brain and learning by bypassing the mental effort needed to build deep neural connections.
- Nov 1, 2026Dr Nigel Peter Symss told News9 Digital that excessive AI reliance may reduce chances to practise remembering and analysing independently, but said there is insufficient evidence that AI use directly causes permanent memory loss or physical brain damage.
- Nov 1, 2026A USNI Proceedings piece cited an MIT study using electroencephalography (a method of recording the brain's electrical activity) that found reduced neural engagement during AI-assisted writing and in a later unaided session.
