Increasing rates of dementia in First Nations populations require culturally grounded approaches to dementia diagnosis and care. To respond to the need for a culturally appropriate cognitive assessment tool, a national team of health services researchers and community partners, guided by a Nakoda Advisory Group, aimed to adapt the Canadian Indigenous Cognitive Assessment tool for a Nakoda First Nation in Carry the Kettle First Nation, Saskatchewan, Canada. The adaptation of the CICA for a Nakoda First Nation community resulted in a slightly modified version of the CICA signalling that the CICA requires minimal adaptation to be used in different First Nations contexts.
