**7. Conclusion**

This chapter pinpoints the issue of multilingualism and describes its implication on personal health. With the instant satisfaction and expediency offered by the rising trend for multilingualism due to the social media, YouTube, Facebook, and Twitter. At both the individual and societal levels, multilingualism offers a plethora of benefits and opportunities. Financial services, researchers, translators, interpreters, chemical, IT, and other human involvement (social) services, as well as other worldwide and globalised sectors, largely rely on language skills to operate for commercial activity and service.

Some of the advantages of multilingualism extend to a wide range of sectors of life for both individuals and communities. In a conclusion, the findings of the study presented in this chapter show that multilingual experience are often advantageous to both the individual and the community.

The fact that multilingualism improves cognitive control suggests that lifelong bilingualism may protect against age-related cognitive decline and potentially delay the onset of dementia symptoms. Bilingualism and multilingualism could be one of the ecological factors contributing to cognitive reserve or brain reserve in this scenario [35].

Interestingly, Peal and Lambert [36], concluded in the their study that bilingual children have an advantage in cognitive and linguistic performance: "Intellectually [the bilingual child's] experience with two language systems seems to have left him with a mental flexibility, a superiority in concept formation, a more diversified set of mental abilities" (p. 20).

It should come as no surprise that prolonged and intense experience has an impact on our minds and brains; huge experience obviously changes the functional connections that result from practise, and the anatomical regions that are recruited for specific tasks undoubtedly alter as well [37, 38]. Neuroplasticity refers to these types of responses to experience. However, in the case of bilingualism, it has long been assumed that any such impacts would be disastrous: "This might be considered evidence that the use of a foreign language in the home is one of the primary causes in creating mental retardation based on intelegience tests," one famous educational researcher wrote in 1926.
