Slowly progressive aphasia, a left temporal variant of probable Pick's disease: 15 years of follow-up.

It is known that word-finding difficulties or anomia are the first signs observed in Pick's disease. We report a 15 year follow-up of a woman who at the age of 52 suddenly developed a speech impairment and only 6 years later showed other cognitive disturbances compatible with Pick's disease. This case demonstrates that nonfluent aphasia and agrammatic aphasia may constitute the first signs of this disease, stressing the importance of prolonged follow-up in such cases.
