“There is nothing ‘natural’ about being monolingual” says neuroscientist Thomas Bak
In recent years, research has shown that bilingualism can delay the onset of dementia by 4 to 5 years – including a study with over 600 patients that Thomas Bak co-authored [note] Bilingualism delays age at onset of dementia, independent of education and immigration status

Our brains were originally designed to be multilingual, managing two or more languages easily. Thomas reckons that, like sedentary lifestyles and an unhealthy diet, the monolingualism that’s come with modern society makes our thinking skills decline faster as we age and can actually make us more vulnerable to dementia in later life.
He will present his case against monolingualism at the Cabaret of Dangerous Ideas on Wednesday 23 August as part of the Edinburgh Fringe Festival 2017.
