C.L., a 55 year old right-handed woman, sought an evaluation for an overall decline in her writing, spelling, arithmetic and reading abilities. These had been present for approximately one year and had led her to resign from her position as a second grade teacher. Lapses of memory occurred occasionally. Despite these deficits, daily living activities remained intact. Her general physical examination and elementary neurological examination showed no deficits. Examination revealed an alert, cooperative and pleasant woman who was appropriately concerned about her predicament. She was fully oriented to time [year, month and day of the week] and place [country, province, city and location of testing] but had only a vague knowledge of current news events [who is the Premier of Ontario?].
