RT Journal Article SR Electronic T1 United states of amnesia: rescuing memory loss from diverse conditions JF Disease Models & Mechanisms JO Dis Models Mech FD The Company of Biologists Limited SP dmm035055 DO 10.1242/dmm.035055 VO 11 IS 5 A1 Ortega-de San Luis, Clara A1 Ryan, Tomás J. YR 2018 UL http://dmm.biologists.org/content/11/5/dmm035055.abstract AB Amnesia – the loss of memory function – is often the earliest and most persistent symptom of dementia. It occurs as a consequence of a variety of diseases and injuries. These include neurodegenerative, neurological or immune disorders, drug abuse, stroke or head injuries. It has both troubled and fascinated humanity. Philosophers, scientists, physicians and anatomists have all pursued an understanding of how we learn and memorise, and why we forget. In the last few years, the development of memory engram labelling technology has greatly impacted how we can experimentally study memory and its disorders in animals. Here, we present a concise discussion of what we have learned about amnesia through the manipulation of engrams, and how we may use this knowledge to inform novel treatments of amnesia.
