Patient MR appears to be suffering from psychogenic, retrograde amnesia. Retrograde amnesia describes the condition in which an individual cannot remember past events leading up to the amnesia causing event. Psychogenic amnesia results from a psychologically traumatizing event. The forgetting is motivated by the need to block out the memory from a certain emotional period.

However, it is possible MR was triggered by being back in Europe which brought back intense emotions leading to the desire to block out the
