Effect of Propofol, Sevoflurane, and Isoflurane on Postoperative Cognitive Function Following Laparoscopic Cholecystectomy in Elderly Patients
Keywords:cognition, memory, mental, motor function.
Cognition refers to the mental action or process through which an individual acquires knowledge solves
problems and makes decisions for the future. In other words, cognition may be defined as the
mental processes which account for the daily activities carried out by an individual. Deficits in these
mental processes tend to affect the memory, attention, verbal and non-verbal learning, visual and
auditory processing, and motor functioning of an individual, thereby resulting in cognitive impairment.
Memory is classified into two types, that is, explicit memory and implicit memory. Explicit memory
involves the conscious recall of the information received in the past while implicit memory refers to the
information or knowledge which is unconsciously and effortlessly recalled.
