What common symptom may worsen oral communication in elderly patients?

Xerosis, or dry mouth, is a common symptom that can significantly impact oral communication in elderly patients. This condition can lead to difficulties in speaking clearly and effectively. When the mouth lacks adequate moisture, individuals may experience discomfort, which can make it harder to form words, maintain a comfortable speaking pace, and produce adequate vocalization. Additionally, xerosis can affect the ability to swallow, leading to concerns about choking or coughing while speaking, further impacting communication quality.

While other options like arthritis, fatigue, and breathlessness might influence communication in different ways, they do not directly interfere with the mechanics of speech as severely as xerosis does. Arthritis could affect the ability to hold a communication device or paper, fatigue might lead to reduced engagement in conversations, and breathlessness could impact overall stamina during lengthy discussions. However, xerosis specifically disrupts the very act of speaking.
