Communication-related experiences of individuals in the early phase of semantic dementia and their families: an interview study

BackgroundSemantic dementia (SD), a subtype of frontotemporal dementia, manifests as verbal symptoms, including social and behavioural deficits, associated with focal atrophy of the frontotemporal lobes. This study aimed to clarify the experiences of individuals with early-onset SD receiving speech and language rehabilitation (hereafter referred to as 'rehabilitation'), with the intent of making it routine, as well as the experiences of their families. MethodsIndividual interviews were conducted with nine families with members who had adopted rehabilitation. Verbatim transcripts were used as data, and analyzed inductively according to the content analysis process. ResultsThe family members realised the changes in the personality and behaviour of the individual with SD early, to the extent that they thought the individual with SD was different from before and were distressed by the loss of verbal communication. Nevertheless, the family members found a way to communicate by maintaining residual functions through rehabilitation and utilising their unique relationship with the individual with SD. ConclusionsIt is important to carefully explain the characteristics of the disease and the long-term significance of rehabilitation to individuals with SD and their families in the early stages of the disease.
