Aging of the brain can lead to a dangerous disease. Dementia involves memory loss, mental retardation and reduced cognitive function. It is believed that hereditary factors and lifestyle influence the probability of this disease.

Spanish doctors have discovered a new method of preventing dementia. The research was conducted by experts from the Open University of Catalonia in Barcelona.

Inhabitants of this Spanish city use two languages ​​- Catalan and Spanish – in their everyday life. Scientists examined 135 patients with mild cognitive impairment, 68 patients with Alzheimer's disease and 63 healthy residents of Barcelona. Among other things, they measured how actively the study participants used both local languages ​​in their daily lives. The results showed that those patients who spoke both Spanish and Catalan in their daily life had cognitive impairment at a later age than those who mainly used one language for communication.

“Active bilingualism is an important factor in delaying the appearance of symptoms of mild cognitive impairment – the preclinical phase of Alzheimer's disease, because it contributes to the formation of cognitive reserve”, – explained the professor of the medical faculty of the university, Marko Calabaria. Scientists are going to find out whether bilingualism helps in the prevention of Parkinson's and Huntington's diseases.
