This chapter presents interdisciplinary and international choreographic and dance movement psychotherapy practice-led research with people living with young-onset dementia, their families, and the artistic team Beatrice Allegranti Dance Theatre with composer Jill Halstead. Established in 2016, the Moving Kinship project 1 comprises overlapping ‘events’ (in the UK, Norway, Netherlands, and Japan), including bespoke participatory dances for families living with young-onset dementia. A touring dance theater production evolved from the bespoke participatory material and was made in collaboration with a professional cast.
