In the present study we report the progressive dissolution of numerical skills in EP, a former teacher of mathematics, suffering from an Alzheimer's- type dementia. The longitudinal examination revealed a pattern of decline different from previous reported cases. An initial impairment in arithmetical procedures was followed by an insidious decay in more basic numerical tasks with a selective preservation of arithmetical facts. The present investigation confirms the functional independence of facts and procedures within the calculation system. Moreover, these findings suggest that in the context of a general cognitive decline, specific numerical skills are more resistant to deterioration.
