To consider national policies to support the development of medical services for dementia, we conducted three studies.
 Study 1: We evaluated the dementia management capacity of clinics using a questionnaire on medical services for dementia. Findings: 1) Clinics that employed doctors who had attended a lecture on dementia management had a superior capacity to provide primary care services, make diagnoses, manage behavioral and psychological symptoms of dementia (BPSD), provide home healthcare for dementia, and promote community integration compared to clinics that did not employ such doctors. 2) Clinics that employed "dementia support doctors" had a superior capacity to provide such dementia management as mentioned above compared to clinics employing doctors who had attended a lecture on dementia management. However, 3) the questionnaire data suggested that only some clinics that employed "dementia support doctors" could provide such medical services as diagnosis of dementia, management of BPSD, and promotion of community integration in their regular clinical practice.
 Study 2: We evaluated the current activities of Medical Centers for Dementia (MCDs). Findings: 1) MCDs had more efficient activities in general compared to Dementia Centers for the Elderly (DCEs) established in 1989 and suspended in 2007. However, there was a large disparity among the facilities in terms of their activities. 2) Many MCDs thought that they could not provide adequate services due to the size of their catchment area. 3) Emergency services for dementia patients with concurrent medical conditions were supported by staff of many MCDs located in general hospitals without the designation of a special MCD for providing emergency services. 4) Inpatient stays tended to be longer in psychiatric hospitals where MCDs were located.
 Study 3: We conducted a preliminary investigation on activities in possible "dementia support clinics". Findings: These clinics had an inferior capacity to provide inpatient services but a similar capacity to make diagnoses, provide management of BPSD, and promote community integration compared to MCDs.
 From these findings, we made recommendations as follows: (1) It is necessary to not only increase the number of "dementia support doctors", but also to develop adequate numbers of "dementia support clinics" that provide such medical services as diagnosis of dementia, management of BPSD, and promotion of community integration in cooperation with community general support centers in regular clinical practice. (2) It is necessary to monitor the level of activities and develop adequate numbers of MCDs based on the size of the area and population. MCDs should take part in establishing community-based, integrated care systems in cooperation with the local government. Equipping "dementia support teams" might be indispensable in general hospitals that provide emergency medical services for dementia patients. (3) It would be significant to arrange "dementia support clinics" as a medical resource to make diagnoses, provide management of BPSD, and promote community integration for dementia in local dementia planning by a municipality.
