The Effects Of Anesthesia On Cognitive Functioning

Research The investigation of how anesthesia effects cognitive functioning has had a long history. Overtime, it has been suggested that there is an association between anesthesia, surgery, delirium, dementia and postoperative cognitive dysfunction (Inan Ozkose Satirlar, 2015). The theory of anesthesia’s impact on cognitive functioning was derived in 1887, by Savage, who began to observe the â€Å"insanity† that follows the use of anesthesia. He suggested that â€Å"Any cause which will give rise to delirium may set up a more chronic form of mental disorder quite apart from any febrile disturbance† (Savage, 1887, p. 1199). Delirium can be defined as an altered level of consciousness that may cause a sudden decline in attention and focus perception (Isik, 2015). Postoperative delirium was reevaluated in 1955 when Bedford used a series of case studies collected over a 50 year span to describe a connection between anesthesia and dementia. The results suggest that 1 0% of the patients had postoperative cognitive dysfunction (Bedford, 1955). Since these initial studies, research has persisted using a variety of methods, in an attempt to determine: both long- and short-term effects of anesthesia on cognitive functioning and memory; whether the anesthesia administration technique will change the outcome of postoperative cognitive dysfunction; and other risk factors that may be associated to AD.
