If you have two languages and you use them regularly, the way the brain_s networks work is that every time you speak, both languages pop up and the executive control system has to sort through everything and attend to what_s relevant in the moment. Therefore the bilinguals use that system more, and it_s that regular use that makes that system more efficient.

Multitasking is one of the things the executive control system handles that is why bilinguals better at multitasking.

Also normally aging bilinguals have better cognitive functioning than normally aging monolinguals. Bilingual older adults perform better than monolinguals on executive control tasks.

Medical records of 400 Alzheimer_s patients show that, on average, the bilinguals showed Alzheimer_s symptoms five or six years later than those who spoke only one language. This didn_t mean that the bilinguals didn_t have Alzheimer_s. It meant that as the disease took root in their brains, they were able to continue functioning at a higher level. They could cope with the disease for longer.
