ABSTRACT
Purpose
Evaluate oral transit time (OTT) with pudding consistency at the different stages of Alzheimer's disease (AD).
Methods
Descriptive, cross-sectional, observational study conducted with a sample of 34 elderly aged 65-98 years, with AD at different stages. Participants were observed using videofluoroscopy of swallowing while ingesting pudding consistency, using the Kinovea timing program. Data were statistically analyzed at 5% significance level.
Results
Participants with Clinical Dementia Rating - CDR 3 presented longer OTT compared with those with CDR 1, with means of 3.09 s (SD = 0.91) and 1.17 s (SD = 1.10), respectively. Individuals aged 90-100 years presented longer OTT than those aged 60-79 years, means of 3.90 s and 1.28 s, respectively.
Conclusion
Individuals with dementia and advanced aged present longer OTT for pudding consistency and should receive special attention from family members and caregivers.
