....and, apart from maybe something related to proteins and the nervous system, nobody can exactly figure out why.

A British man lost the ability to create new memories after going to the dentist for a routine root canal, according to a recently published study. Notes from this "astonishing" case were recently published in the journal Neurocase.
After undergoing a root canal procedure in March, 2005, the 38-year-old man lost the ability to remember anything beyond 90 minutes, meaning he can't make any new memories, the University of Leicester said in a statement. Each morning, the man wakes up believing it is the same day in 2005 that he went to the dentist.
Gerald Burgess, the study's lead author and lecturer at university, said his team has "never seen anything like it before." The man was referred to Burgess as a patient almost 10 years ago, when Burgess was working as a clinical psychologist. Throughout the study the patient is referred to as WO.
The year of the procedure, WO was a member of the U.K. military and was stationed in Germany. He had joined the army at the age of 17, served in the first Gulf War, and married at the age of 22. He and his wife have two children, the study said.
Eventually WO and his family moved back to his childhood home in the U.K. According to the study, he recognizes his home, places in his hometown and the general geography of the town. However, he still wakes up every day believing that it's the same day of the appointment.
"In general, each morning he is surprised to wake up in his mother's house. He wakes up believing that he should still be in the military, stationed abroad," the study said. "Every day he thinks it is the day of the dental appointment."
According to the study, WO can still recall events that happened in his life up to the day of the root canal. He can even remember receiving the anesthetic and the moment the dentist began drilling. But anything that has happened to him since, he can only retain in his memory for about 90 minutes. Now, WO relies on the help of his wife and an electronic diary to keep track of his daily activities.
While his wife reports "subtle differences" in his personality, including becoming more easily frustrated and intolerant, WO is aware of his own identity and that of his family, the study said. (He expects, however, everyone to still be the age they were in 2005).
The study added that WO is aware that he has a memory problem, but requires his wife to answer questions about events that have happened since March, 2005.
Now, Burgess is appealing for anyone with knowledge of similar cases to contact him so he can further investigate. This is why he published the case notes, he said.
"One of our reasons for writing up this individuals case was that we had never seen anything like this before in our assessment clinics, and we do not know what to make of it, but felt an honest reporting of the facts as we assessed them was warranted, that perhaps there will be other cases, or people who know more than we do about what might have caused the patients amnesia," he said in a statement.
He stressed that at this time it would be "unethical" to blame the anesthetic or root canal for the memory loss.
