How to make food safe and palatable for the very elderly:
Communication Predicament of Aging model:
Communication enhancement model:
How does language change as people become elderly?
What happens with phonology and orthography in aging?
PERCEPTION: 1. Decline in sensory processes: - visual and auditory acuity 2. Decline in cognition/processing: -speech in noise -speech rates PRODUCTION: 1. Decline in word retrieval 2. Decline in spelling
What happens with semantics in aging?
PERCEPTION: **Area of STRENGTH until very old age** -Slower processing of speech -better vocab (education) PRODUCTION: -Decreased density of ideas in discourse - More off-topic speech -maybe communication goals are different -> rich story telling
What happens with syntax in aging?
PERCEPTION:
- declines for text with greater sytactic complexity
- ?working memory declines
PRODUCTION:
-Decline in syntactic complexity in spoken and written language (fewer left-branching sentences)
Some challenges with diagnosing communication/swallowing difficulties in elders:
Factors which impact on speech and swallowing changes in old age:
What imact to respiration changes in aging have on speech, swallowing and voice?
Cognitive Model of aging 1 - Resource theory:
Premise: Human capactiy for processing information is limited
Cognitive Model of aging 2 - General Slowing theory
Cognitive Model of aging 3 - Inhibition deficit theory
Cognitive Model of aging 4 - Working memory theories
Cognitive Model of aging 5 - Transmission deficit theory
Cognitive Model of aging 6 - Degraded signal theory
Some age-related swallowing differences:
Changes in swallowing during aging -> anticipatory (before pre-oral)
¯ sense of smell
¯ sense of taste
¯ perception of thirst (men)
¯ regulation of fluid intake (men)
Changes in swallowing during aging -> pre-oral and oral phases:
¬ number of chewing strokes ¬ time to complete oral phase ¬ retention post swallow ¯ tongue driving force (necessary to propel the bolus into the oropharynx) ¯ suction pressure during straw drinking
Changes in swallowing during aging -> Pharyngeal stage:
-Delay in triggering the swallowing reflex
¬ pharyngeal transit time (women); possibly higher pharyngeal contraction amplitudes
¬ pharyngeal residue post-swallow
¬ penetration no increase in aspiration
more than one swallow needed to clear the bolus
¯ laryngeal excursion reserve (men)
¯ laryngeal and pharyngeal sensation
Changes in swallowing during aging -> Oesophageal phase:
¯ oesophageal transit speed
¯ oesophgeal clearance efficiency
¯ amplitude of the oesophageal pressure wave, but no change to duration (time) and velocity (speed) of the pressure wave.
Evidence based practice (EBP) involves integrating and utilising the best available evidence from empirical research, clinical expertise, client values and preferences, as well as knowledge of context-specific factors to make decisions about the care and management of individual clients.

Family centred practice involves “Helping families to identify concerns, priorities, and resources for their child [or family member] and including them as integral members of the intervention team”
