Bilingualism can counteract dementia because it stimulates the alternation between languages.

Bilingualism, i.e. the ability to understand and speak two languages at the same time, can act to combat dementia according to a study conducted by researchers at Universitat Pompeu Fabra, Barcelona together with colleagues from other Spanish institutions.
The researchers analysed more than 100 bilingual or monolingual patients with mild cognitive deficits with an average age of 73 years. The subjects spoke both Spanish and Catalan.

According to César Ávila, one of the authors of the study, the alternative use of these two languages simultaneously on a cognitive level is complex precisely because there are many similarities between them and therefore one needs to be more vigilant and more attentive in order not to get confused.
After following the evolution of the patients during seven months, the researchers found that the bilingual ones showed a lower loss of brain volume while maintaining generally better cognitive abilities.

According to the researchers “there is a cognitive reserve of bilingualism” and this mechanism exists thanks to the cognitive stimulation that is fostered by the alternation of use between languages.
These are interesting results, according to the authors themselves, because it is one of the first studies that shows the possibility that there is in fact a kind of protection by bilingualism against dementia and that explains its mechanism.
The possibilities of therapies to stimulate patients suffering from dementia on a cognitive level through practical exercises in the use of different languages are now becoming more concrete.
