Although pharmacy students receive professional education regarding dementia, it is the current state that many pharmacy students cannot learn the countermeasures to treat people with dementia. We conducted the “Otani dementia supporter education lecture” which improved a lecture by Caravan Mate targeting pharmacy students, and subjected the students to a questionnaire survey after the lecture. One hundred and forty-nine students participated and there were most percentages of third grades by 40.9%. After attending the lecture, most of the students opined that one can help a patient with dementia by understanding the patients’ feeling. It was the answer obtained by the lecture for the students to ensure that a pharmacist responds to consultations and requests from their family with a dementia patient. The first information that the students additionally wanted to know about dementia pertained to a method for the early detection of dementia. The results of text mining on the correspondence for patient with dementia showed that categories of “dementia patient,” “correspondence,” “understanding the patients’ feeling,” and “tact,” independently had strong mutual relations. Moreover, the results of text mining on the feedbacks obtained for the lecture showed that categories such as “dementia patient,” “When close person and one were,” “A chance was obtained,” and “correspondence” independently had significant mutual relations. Students who participate in this lecture understand that it is necessary to contact with dementia patients appropriately and feel that there is a need to become a presence that can support dementia patients as a pharmacist in the future. Therefore, this lecture was effective in motivation to correspondence to a person with dementia.
