Presbyphagia Flashcards
what is presbyphagia
difficulty swallowing due to aging
what are the main causes of presbyphagia
decreased cognitive function, taste, olfaction
loss of teeth
reduced muscle strength
altered salivary secretion
impaired reflexes
anatomical changes
how does decreased cognitive function impact swallowing
reduces awareness and control over the swallowing process, making it more difficult
how does loss of teeth contribute to presbyphagia
impacts the ability to chew food properly which is crucial for oral prep stage
what roles does muscle strength play in swallowing
affects the ability to move food through the mouth, throat, and esophagus
how do changes in taste and smell affect swallowing in older adults
decreases interest in food and can lead to less preparation for swallowing
what happens in the oral preparatory stage?
human interest to eat
what can impair the oral prep phase?
decreased cognitive function, muscle strength, and loss of teeth
what happens during oral transport stage?
tongue pushes the food bolus toward pharnyx
soft palate prevents food from entering nasopharynx
pharyngeal phase
bolus enters the pharynx and reaches the esophagus
what issues can impact pharyngeal stage?
impaired cough and swallowing reflexes
anatomical changes of hyoid bone and larynx
decreased tongue root retraction
incomplete UES opening
reduced pharyngeal constriction
what occurs during the esophageal stage
bolus passes through esophagus with the help of peristalsis and gravity
lower esophageal sphincter opens allowing food into the stomach
what can impair esophageal stage?
decreased esophageal motility
why is it important to address presbyphagia in older population
awareness and intervention are important for improving swallowing safety and preventing complications
3 main types of function degradation in presbyphagia
primary
anatagonistic
integrative
primary presbyphagia
normal aging processes that directly affect function
antagonistic presbyphagia
changes that counteract other processes
integrative presbyphagia
interactions of multiple factors contributing to swallow decline
treatment options
rehab
screening
assessment
procedures
