The evidence of cognitive deficit is obvious among the elderly population and needs to be tackled very effectively in keeping the view of maintaining functional independence in their routine activities. Throughout the chapter, different phenomena related to age-associated disorders and comorbidity have highlighted the high frequency of cognitive impairment and we will also be going to know about the role of the COVID-19 pandemic in worsening these symptoms.
