This study evaluated the effects of PAROT for elderly people with dementia in Japan. The patients had mild to severe dementia, and all including two participants with severe dementia completed the study. Research on remi- niscence therapy to date has focused on intervention techniques involving the use of language, and are thus well suited for patients with relatively mild to moderate dementia; yet, this dependence on language rules out this approach for patients with severe dementia. By contrast, our intervention approach involves an everyday activity that the patients performed many times in the past, and does not necessarily require communication skills at all. This suggests the possibility that our intervention tech- nique could potentially help patients with severe demen- tia who have lost much of their ability to communicate verbally.
