Aging swallow
| Term | Definition |
|---|---|
| Sarcopenia | progressive and general loss of skeletal muscle mass and strength, and or physical performance Presbyphagia: the degenerative changes in swallowing functions that occur in healthy aging |
| Frailty | loss of strength with accompanying loss of ability to compensate for weakness |
| Presbyphagia | the degenerative changes in swallowing functions that occur in healthy aging |
| Decreased sensitivity to taste, chewing issues due to tooth loss, longer oral transit time, more time chewing, more time to create tongue pressure, oral residue | Oral phase deficits with age |
| delayed swallow trigger (need larger bolus), reduced hyolaryngeal elevation and excursion, increased pharyngeal transit time, decreased pharyngeal constriction, pharyngeal residue | pharyngeal deficits with age |
| less secure closure of upper esophageal sphincter at rest, lower amplitudes of peristaltic movement, reduced sensory perception in esophagus | esophageal deficits with age |
