Stroke may involve diminished salivary output. Which of the following best describes this consideration?

• A. Diminished salivary output
• B. Increased salivary output
• C. Normal salivary output
• D. No salivary flow changes

Answer: (A)

Stroke can disrupt the neural control of the salivary glands, reducing parasympathetic drive that normally stimulates saliva production. This results in hyposalivation, or diminished salivary output, which commonly leads to a dry mouth. Saliva is important for lubricating the mouth, aiding swallowing, and protecting oral surfaces, so reduced flow increases the risk of mucosal irritation, swallowing difficulties, and dental caries. Medications often used after stroke, such as anticholinergics or some antihypertensives, can further lower salivary output, compounding the issue. Therefore, diminished salivary output best describes the consideration in stroke patients, rather than increased, normal, or unchanged saliva flow. In management, address hydration, use saliva substitutes or stimulants as appropriate, maintain good oral hygiene, and review medications that may contribute to dry mouth to help mitigate these effects.
