Did you know that being bilingual offers some protection against Alzheimer’s? Ellen Bialystok, a psychology professor at York University in Toronto, studied 450 Alzheimer’s patients (half monolingual and half bilingual). Bilingual patients with Alzheimer's symptoms were diagnosed between four and five years later than the monolingual patients with Alzheimer’s symptoms. Mastering a second language appears to strengthen the brain in ways that seem to delay developing Alzheimer's disease later on. Just as a regular physical exercise program can keep your physical body in good shape well into your senior years, an effective mental exercise program can do the same for your brain. If you’re not bilingual and don’t want to learn another language, stimulate your brain daily with challenging brain aerobic exercises.
