By now, just about everyone acknowledges the historical contribution of Arnold Pick to describe frontotemporal atrophy, but Pick's disease often is restricted to designate the histological variety with Pick bodies. Considerable progress in histochemistry, tau biology, genetics, and clinical description inevitably resulted in the proliferation of new terminology. Various efforts to rationalize terminology and achieve clinicopathological and nosological consensus have been made, 1-3 and the organizers and participants of this meeting felt these efforts should continue incorporating all the disciplines and centers interested in the disease. The conference included substantial participation from behavior and language specialists, motor neuron and movement disorder groups, pathologists, geneticists, biochemists, and epidemiologists. We constructed a survey form, the text of which is reproduced below, and distributed it to all invited core participants. Of the 30 participants, 27 responded by the end of the meeting. All the responders endorsed the statement that rationalizing terminology was a worthwhile effort, and many wrote supportive comments. Arguments in favor and against each term were included in the survey, but are reproduced here only for the major items. We asked participants to circle one choice or suggest another term. Tallies of their responses are indicated in boldface numbers.
