Which is a normal age-related change?
Decreased secretion of saliva
Increased acidity of saliva
Decreased gastric emptying
Increased peristalsis
The Correct Answer is C
A. Decreased secretion of saliva
This is not a normal part of aging; if present, it's often due to medications or illness.
B. Increased acidity of saliva
Salivary composition doesn’t change significantly with age; this is not a recognized normal change.
C. Decreased gastric emptying
Aging can slow down GI motility, leading to delayed gastric emptying, which can contribute to fullness or indigestion.
D. Increased peristalsis
GI peristalsis slows with age, increasing the risk of constipation, not increasing motility.

Correct Answer is C
Explanation
A. Accelerated loss of neurons in the brain
Neuron loss occurs gradually. "Accelerated" implies rapid degeneration, which would be pathological, not normal aging.
B. Increased conduction speed of neurons
This is incorrect; aging is associated with decreased conduction speed due to demyelination and slower synaptic transmission.
C. Decrease of short-term memory
Short-term memory loss is a common age-related change in cognition, even in healthy aging.
D. Gradually declining loss of intellectual capability
While processing speed may decline, intellectual capacity (such as vocabulary and long-term memory) is generally preserved in normal aging.
