We also are very interested in this. Margaret, when asked what she was thinking during an apparently catonic episode, can only reply "nothing". The kind of episode that concerns us is a period of inattention such that her electric scooter can veer off the footpath. Not so much 'revving the motor in neutral' as failing to have the mind in the right gear. Indeed, with hindsight, we can see that it was this kind of inattention rather than simple motor problems (if you will pardon the pun), that led to her relinquishing her driving license perhaps 12 years ago. To us, the term fugue, with its repetitive musical connotations, well describes the condition which seems to impede the transition from automacity to conscious action.
