Avaliação fonoaudiológica da deglutição na demência frontotemporal

Abstract

The behavioral characteristics that were significant in the comparison between bvFTD and PPA groups were delirium, disinhibition, aberrant motor behavior and sleep disturbances (p <0.05), and hallucinations (p = 0.01). Patients with bvFTD had more swallowing problems than patients with PPA, such as coughing and choking, difficulty with some food consistency and difficulty with specific food. Swallowing problems in bvFTD correlated with functionality, with the cognitive aspects (p <0.05), with executive function and behavior (p <0.01). In PPA, the semantic subtype showed more swallowing problems such as escape of saliva and food in mouth, multiple swallows, delay in initiation of swallowing and choking, these characteristics correlated with anxiety (p <0.01), apathy and aberrant motor behavior (p = 0.01). The problems of feeding behavior were more frequent in logopenic subtype and correlated with communication difficulties. The major predictors of worsening of swallowing function were: functional decline, behavioral changes and impaired communication. Swallowing problems were observed at all stages of dementia. The BAF was the only instrument that had bad internal reliability. Conclusion: Swallowing problems were observed in the two variants from the early stages of dementia. Behavioral, cognitive and functional changes, and difficulties in communication compromised the anticipatory and oral preparatory phase of swallowing. Because of these changes, caregivers had difficulty in managing the feeding situation. Our study developed reduced versions of questionnaires to assess swallowing and functional communication.
