Objective To determine how older people with dementia and their family caregivers experience dementia assessment services and preferences for future configuration of diagnostic services. Methods Qualitative, semistructured in‐depth interviews were conducted with nine individuals with dementia. In seven instances, the caregiver also took part in the interview, and on two occasions, the interview was with the person with dementia only. Results An important contact during assessment of dementia was the general practitioner, in particular working in a way or timeframe which provides clarity and comfort to the person with dementia and their family members. A problematic factor in clear diagnosis was when probable dementia was suspected during hospitalisation for another complaint. Participants expressed a wide range of views in terms of preferred settings for diagnostic services. Conclusion These findings highlight some key considerations, which should be included in future research leading to decisions about the design of dementia client services.
