Briton man left with just 90 minute memory

London: A Briton who can only remember up to 90 minutes and bears a striking similarity to the memory loss presented in movies like "Groundhog Day" and "Memento" may be a unique case never seen before, say psychologists from University of Leicester.

The 38-year-old fit and healthy man suffered memory loss after local anaesthetic and root-canal treatment. For the past decade he can only remember up to 90 minutes and awakes every morning thinking it is the same day he went to the dentist. There is no evidence that the treatment at the dentist can be blamed for his condition, the psychologists who described the study in the journal Neurocase said.

The doctors are now appealing for people who know of someone who might have suffered similar symptoms of memory loss, or medical or allied health professionals working with someone like this, to contact them in order to build up knowledge and evidence in this field. He is fully aware of his identity and his personality did not change, but every day the man thinks it is the day of his dental appointment.
