Which condition is characterized by slurred speech?

  1. Dysphagia

  2. Dysarthria

  3. Dysphonia

  4. Dysmorphia

The correct answer is: Dysarthria

Dysarthria is a motor speech disorder resulting from neurological injury, which leads to difficulties in articulating words. It is characterized by slurred or slowed speech that can be difficult to understand. This condition occurs due to weakness in the muscles involved in speaking, which can result from various conditions such as stroke, brain injury, or neurological diseases. In contrast, dysphagia refers to difficulty in swallowing, dysphonia involves trouble with voice production, often affecting volume or quality, and dysmorphia typically relates to a distorted body image or appearance. Each of these terms addresses different aspects of communication and physical capability, making dysarthria specifically the correct choice in relation to slurred speech.
