Pharmacists’ essential knowledge on cognitive impairment in the elderly population

Abstract

Background: There are various factors which can lead to irreversible, reversible cognitive impairments. The progression of reversible cognitive disorders can be halted by identifying and treating the underlying cause. Aim of the Review: To expand pharmacists’ knowledge on underlying causes of cognitive impairment and investigate the possibility of pharmacist involvement in the identification of and/or protection against cognitive impairment. Method: A search of the literature was conducted through databases to identify studies in the English language of 1975-2016. Peer-reviewed articles and informational websites were included. Results: There are two broad classifications of cognitive impairment, irreversible and reversible cognitive impairment. Pharmacists can play an essential role in early detection of cognitive impairment caused by medications. Conclusion: Pharmacists have the potential to lead early detection of cognitive impairment caused by medications through appropriate management of the underlying problem. This may contribute to patients’ better health outcomes and quality of life.
