We examined ambulatory clinical training for patients with dementia conducted by residents at a university hospital and instructors at a psychiatric hospital who mainly treat patients with dementia in the General Internal Medicine Department of a regional hospital. Residents experienced dementia treatment in the context of primary care, and performed in-depth learning about dementia with the guidance of psychiatrists. It is hoped that dementia treatment will be provided by family doctors. Moreover, it is expected that doctors who have undergone this training will contribute to dementia treatment.
