Pathways to diagnosis: exploring the experiences of problem recognition and obtaining a dementia diagnosis among Anglo-Canadians.

Increasing evidence suggests that early diagnosis and management of dementia-related symptoms may improve the quality of life for patients and their families. However, individuals may wait from 1-3 years from the onset of symptoms before receiving a diagnosis. The objective of this qualitative study was to explore the perceptions and experiences of problem recognition, and the process of obtaining a diagnosis among individuals with early-stage dementia and their primary carers. From 2006-2009, six Anglo-Canadians with dementia and seven of their carers were recruited from the Alzheimer's Society of Calgary to participate in semi-structured interviews. Using an inductive, thematic approach to the analysis, five major themes were identified: becoming aware of memory problems, attributing meanings to symptoms, initiating help-seeking, acknowledging the severity of cognitive changes and finally obtaining a definitive diagnosis. Individuals with dementia reported noticing memory difficulties earlier than their carers. However, initial symptoms were perceived as ambiguous, and were normalised and attributed to concurrent health problems. The diagnostic process was typically characterised by multiple visits and interactions with health professionals, and a diagnosis was obtained as more severe cognitive deficits emerged. Throughout the diagnostic pathway, carers played dynamic roles. Carers initially served as a source of encouragement to seek help, but they eventually became actively involved over concerns about alternative diagnoses and illness management. A better understanding of the pre-diagnosis period, and the complex interactions between people's beliefs and attributions about symptoms, may elucidate some of the barriers as well as strategies to promote a timelier dementia diagnosis.
